CHAPTER ONE INTRODUCTION 1.0 BACKGROUND OF THE STUDY This chapter introduces what solid waste is all about including its quality and effects on underground water. Solid waste commonly known as trashes or garbage are wastes consisting of every of day items we consume and discard. It predominantly includes food waste, yard wastes, containers, product packaging and over miscellaneous inorganic waste from residential, commercial, institutional and industrial resources. Underground water is the water found from beneath soil underground. Underground water occurs as a result of rainfall entering the soil surface. It may also occur as a result of percolation from the surface into the soil. When rain falls to the ground, the water does not stop, some flow along the surface to the stream or lakes, while some are used by plants, some evaporates and return to the atmosphere, while some sink into 1 the ground.when pouring a glass of water into a pile of sand, it is obvious that the water will move space between particles of sand. Scientifically, groundwater is found in the cracks and spaces in the soil, sand and rocks. It moves slowly through layers of soil, sand and rock called aquifers typically consist of gravel, sand, stone or fractured rock, like limestone. These particles are permeable because the large connected space that allow water to flow through the speed at which groundwater flows depends on the size of the spaces in the soil or rock and how well the spaces are connected. The area where water fall aquifer is called the saturated zone (or saturation zone). The top of the zone is called the water table. The water table may be leaked either a meter below the ground surface or it consist of thirty metre down. Groundwater can be found almost everywhere. The table water may be deep or swallow and may rise or fall depending on many factors. Heavy rains or melting snow can cause the water table to rise or heavy fumbling groundwater supplies may cause the water table to fall. 2 Water in aquifers is brought to the surface naturally through spring can or be discharged into lakes or streams. Groundwater can also be extracted well drive into aquifers. A well is a pipe in the ground that fuse with groundwater. The water can be brought to the surface by a pump. Some wells call artesian wells, do not need a pump because of natural pressure that forces water up and out of the well. Groundwater supply are replenished or recharged by rain and snow melt. In some areas of the world, people face serious shortages of water because groundwater is used faster than it is naturally replenished or recharged. If ground becomes polluted it will not be safe to drink. Ground water is used for drinking water by more than 50% of the people. In the united states including almost everyone who lives in rural areas. It is important for all of us to learn how to protect our groundwater because of it’s important as a source of water for drinking and irrigation. In other areas groundwater is polluted by human activities in area where material above the aquifer is permeable pollutant can be easily sink into the groundwater. Groundwater can be polluted by landfills, septic tanks, leaking 3 underground gas tank and from over use of residual single and multi-dwellings, food wastes, wood, papers cardboard, textile leather, yard wastes, glass metals, ashes spell waste (bulky, items, tyres) and household are hazardous wastes. Industrial light and heavy manufacturing, fabrications power and chemicals and plants, housekeeping waste, packaging, food wastes, construction and demolition materials ashes are special waste. In other words, waste from hotels, resturants, markets, office building (paper, cardboard, food plastic, glass metals). Institutional schools, hospitals, prisons, government centres, heavy and light manufacturing refineries, chemical plant material extraction, industrial scrape materials, municipal services, street cleaning, land scraping, parks, bleaching, recreational areas, water and waste water management plants contribute immensely to the contamination of groundwater and they are the most common sources of waste generation. It is noted that solid wastes have a great effect on the quality of underground water as 4 a result of percolation, infiltration, leachate and disintegration of waste materials by the action or rainfall into the ground. 1.2 PROBLEM OF THE STUDY The problem of solid wastes and its effect on the quality of underground water is now the focus of attention all over the world. The problem of waste generation in the country in the recent past has been quite tremendous necessitating the need for this project. In fact, the presence of waste scattered all over cities and towns and even in institutions of higher learning is a threat to health and embarrassment to the pleasant standard expected of those areas. The menace of solid waste generation is most prominent in develop and industrialized countries; this is because complexity of generated waste is directly proportional to development operation of in science landfilling and technology. material, Construction recovering system and and incineration system has become very costly. It is noteworthy that the urban populace generates more waste than the rural areas. 5 this is because of the various form of commercial and industrial activities going on in cities and which has brought an increase in the volume and diversity of waste generated daily in the country. These have some great effects on the underground water consumption (borehole and well). It is therefore believed that in consumption of underground watersuch as borehole and well water certain tests needed to be carried out before consumption in regulation with the principles of World Health organization. These tests are; PH test Total coliform test Test for nitrate [No 3-N] Aerobic and sulphate reducing bacteria. These tests are most important test carried out to know the physical, chemical and biological effect of solid waste on underground water before it could be suitable for consumption. 6 In addition, waste is such item which people are required to discard. It can be defined as unavoidable material resulting from the activities which has no immediate economic demand and must be disposed of. Items such as household rubbish, sewage sludge waste from manufacturing can give to a large variety of different waste from different sources. Waste are generated every day in all part of the world (Oluwamde, 1973). This is mainly made up of waste coming from household, commercial activities (e.g. shops, restaurants, hospitals) industry (e.g. pharmaceutical companies, cloth manufacturers etc.) agriculture (slurry) construction and demolition projects, mining and quarrying activities and from the generation of energy. With such vast quantities of waste being produced. It is of vital importance that it is managed in such a way that does not cause any harm to either human health or the environment. 7 1.3 PURPOSE OF THE STUDY. 1. To know the physical, chemical and biological effects of solid wastes on underground water and to dermine the amout of waste within the study area. 2. To determine whether the water pollution have dangerous effect on the people and animals in the area of study or environment. 1.4 OBJECTIVE OF THE STUDY 1. To prevent all individuals, relevant organizations, researchers from drinking underground water that is very close to dumping areas in order to avoid deadly diseases. 2. To inform the people on the hazard and result of waste to their health from drinking underground water especially those that are very close to dumping areas in order to prevent untimely death. 3. To educate people on the population to health, 8 negative effects of water 1.5 SCOPE OF THE STUDY The study covers the town of Ikirun in Ifeiodun Local Government in Osun State, South-West of Nigeria with thirty local governments, only one town was explored by the researcher. Ikirun is centrally located in Osun North-East division of Osun State with latitude 7 degrees, 50 feet north of Equator and longitude 4 degrees, 40 feet east of Green w” meridian. It is bounded on the north by Inisia town in Ado-oti Local Government Area, on the south by Osogbo, the Osun state capital, to the east by Iragbiji town in Boripe Local Government and to the west by Eko Ende town also in Ifelodun Local government. In these towns, different wells are examined both in dry season and rainy season especially those that are very close to the dumping area. The difficulty encountered during the course of this project was my inability to perform some tests which are very expensive. This was due to the fact that required initial fund to carry them out. Example of such tests are aerobic and sulphate reducing bacteria tests etc. 9 1.6 DEFINITION OF TERMS 1. Percolation: this can be defined as the slow passage of liquid through a filtrating medium. It is also known as the process of water seepage through the soil. 2. Leachate: This is any liquid that in passing through matter extracts, slows, suspends solid or over components of the material through which it passed. 3. Infiltration: the process by which water on the ground surface enters the soil. 4. Hazardous substantial Wastes: or these potential are threats wastes to public that poses health or environment. 5. Aquifers: These are underground layers of porous rocks or sand that allow the movement of water between layers of non-porous rocks (sand stone, gravel or fractured lime stones or granule). 10 6. Waste Prevention: It is the method of eliminating waste at source and reducing the demand on natural or origin resources. 7. Waste Re-use: It is the method of using a waste product from one process as a raw material to form another. 8. Waste Recycles: This is the process of breaking down the waste. 11 CHAPTER TWO 2.1 LITERATURE REVIEW After examining some of the literature in this area, it became readily apparent certain groups or states had conducted and are still conducting research on waste products. Since early 1950’s, there has been more activity in the state of California in this regard than any other states in the United State of America. One of the first study was an in depth investigation on the leaching of soluble salts and alkaline from incinerator ash dumps (state of California 1952). Following this study, the city of Riverside solid waste dump was used as the site for investigating of the leaching properties of typical municipal refuse (State of California1956) reports. Conclusion from the carried out respectively regarding the effect of solid waste on groundwater quality are; 1. Solid waste if so located that no portion of it intercepts groundwater will not cause impairment of the ground water for either domestic or irrigational uses. 12 2. Solid waste if so located as to be intermittent or continuous contact with groundwater in the vicinity of the solid waste to become grossly polluted and unfit for domestic or irrigational uses. 2.2 DEFINITION OF WASTE According to U.K’s Environmental Protection Act 1990, waste are substance which constitute of scraped materials, efficient or other unwanted surplus arising from application of any process of any substance or article which requires to be disposed of which has broken, worn-out, contaminated or otherwise spoiled. In relation to Waste Management Licensing Regulations of 1994, waste is any substance which the producer or the person in possession of it discards or intends or required to discard but with exception or anything exclude from the scope of waste directive. 13 2.3 SOURCES OF SOLID WASTE Waste are produced and the sources, the quality and composition of refuse are determined by the features or the source. These sources are domestic/residential solid waste. 2.3.1 DOMESTIC RESIDENTIAL SOLID WASTES: This category includes rejected solid materials that emanated from shop residential owners units. and It household contains unit organic consumption materials. It from usually produces a very bad odour. Rubbish/Trash: This category consists of paper and product plastic cans, bottles, glass metals, ceramic dirt, dust and garden waste. They are mainly non-putrescible. Ashes: This type of waste is the residual from any combustion process, e.g. firewood etc. resulting from household activities. 14 2.3.2 COMMERCIAL AND INSTITUTIONAL WASTE They are mainly from banks, office, retail stores, restaurants schools, hospital etc. apartfrom garbage rubbish and ashes. Other types of waste which also fall under this category are: Construction and Demolition Waste: These includes planks, blocks, concrete, muds, plumbing and electrical wiring. Some of them depends on the economy or their use. Special Waste: They are usually solid and solid material generated by special equipment in places like hospitals and research laboratories. They include explosives, pathogenic materials etc. they are specially collected and incinerated because of their hazardous nature. Municipal Solid Waste: These category includes the solid residue that results from the municipality function services. Others include; 15 Street refuse Dead animals Abandoned vehicles 2.3.3 Industrial Solid Waste These are of two categories; commercial and institutional components and processed solid waste. The separation is due to the difference in the quality and characteristics of the refuse. Commercial/Institutional Waste: Are produced by the office staff, the cafeteria and personnel related activities. Process Waste: are the residuals from manufacturing process due to the fact that no plant is 100% efficient. as a result, there will be raw materials and products that will form waste. Agricultural Residue: They are more prominent in the rural areas majorly because of the problem they contribute. 16 Crop residue; such as corn, wheat and soybeans are left and they can serve as manure for soil. 2.4 PHYSICAL AND CHEMICAL HAZARD OF SOLID WASTE: A problem frequently overlooked is that of physical and chemical hazard that can result from certain components for examples; 1. Explosion hazard of solvent gasoline etc. 2. Toxic chemicals used as pesticides solvents etc. 3. Direct contact infected cuts, abrasions resulting from contacts with broken glasses and sharp objects heavily contaminated with bacteria. 2.4 WATER POLLUTION FROM SOLID WASTE: Sanitary landfills are recent technology that has been gaining ground. In the past, disposal sites were better definedas dumps although there still exists many dumps all over the 17 country. Little attention was given to the manner in which the refuse was placed and soil cover was used occasionally. The population density and the cost of having therefuselong distances requiring many of this disposal sites to be located close to the populated areas. In the large urban areas of the country like USA, the refuse was generally incinerated. In the smaller communities, the lower population density made it possible to find land areas relatively close by that could be used for refuse disposal. Unfortunately, there was no local pressure that require the design and operation of engineered disposal sites. Consequently, most of the refuse were simply dumped at allocation or sites. No efforts were made to control the access to water to the site. In fact, it was uncommon to dump refuse into excavated land or gravel pit that was full of water. 18 2.5 SOURCES OF WATER: Water is a liquid material that comprises of two different elements. Hydrogen and oxygen. It is the most important component in the universe and it is required in all chemical reactions. Surface water: this occurs as the result of the precipitation that is absorbed by the ground or evaporated back into the atmosphere. Surface water becomes surface runoff as it flows into the stream, lakes and wet land reservoir etc. Groundwater: this results from the precipitation that infiltrates into the ground and sip downward through fractures, pores and other spaces in the soils and rocks. According to Matida Campbell, 2001. Sources of water includes rain water, spring, river and lakes, surface well, deep or artesian wells and tap water. Rainwater: this takes up dusts and gasses from the air and organic matters from the roofs over which it is collected. The long 19 storing cistern gives bacteria opportunity to grow in large numbers causing the water to be unsafe for drinking. Spring water: this water is a source of pure water supply, if is not contaminated by passing through soil which is polluted. Rivers and lakes: these are common sources of water supply but they may be made unfit for drinking. If the surface water and sewage from towns and cities are allowed to drain into rivers. Surface well: these are unsafe sources of drinking water supply and the water should never be used when there are cesspools, drains, barnyards or any other sources of contamination with a radius of 60m of them. Deep Artesian well: these furnish pure water as a rule unless the piping is well tightly joined. When impure water from a subsoil stream near the surface may enter the pipes. Tap water: this is drinking water which comes from an indoor tap or spigot. It is part of a larger indoor pumping system which reverse a complex supportive infrastructure including stable water. Source piping and filtration to keep due water safe .it is 20 the safest source of drinking. The germs present in the water are being killed through test (e.g. biological, chemical and physical test), before it is consumed by an individual. 2.6 PHYSICAL PROPERTIES OF WATER Water covers more than 70% of the earth surface, scientist estimate that the atmosphere contains about 1.3 billion cubic kilometers of this substances, mostly in form of liquid (water) that occupies the topographic depression on the earth (pid Wire.M.. 2006) the second most common from the water molecule on the planets is ice, if all our planet is ice method, sealevel would rise about 70-meter water is also essential for life. Water is the major constant of almost all life forms most animal and plant contain more than 60% of water by volume. The molecular polarity causes water to be a powerful savantand is responsible for its strong surface tension. Water has a high specific heat that can be define as the amount of energy required to change the temperature of a substance. Because water has a 21 highspecific heat. It can absorb large amount of heat energy before it begins to get hot. Water conduct heat more easily than any other bodiesliquid except mercury. this fact causes large bodies of liquid water like Lakes and Oceans to have essentially a uniform vertical temperature profile. Water molecules exist in liquid from over an important range of temperature from 00c to 1000c. this range allows water molecule to exist as a liquid in most places in our planet. Water is a universal solvent. It is able to dissolve a large number of different chemical compounds. This feature also enables water to carry solvents nutrients in run-off infiltration and underground flow. Water is adhesive and elastic and tends to aggregate in drops rather than spread out over surfaces as a thin firm. This phenomenon also causes water to stick to the sides or vertical structure despite gravity’s downward pull. Water’s high surfaces tension allows plant to move (and dissolved nutrient) from their 22 leaves and movement of blood through tiny vessels in the bodies of some animals. 2.7 EFFECT OF RAIN WATER ON UNDERGROUND WATER Rainwater is known as the purest form of water. but it is being contaminated by some particles. In the atmosphere an important measure of water quality is its PH. The letter (PH)describes the acid of basic nature of a substance. Scientifically, a liquid PH is a measure of the concentration of the hydrogen ions (Hi) it contains. The Danish S.P.L Sorenson Originally proposed the concept of the PH scale in 1909 as a method to describe the acidity of beer. The PH scale ranges from 0 to 14 with a value of 7 indicating a natural PH (neither acidic nor base) distilled water has a PH of 7 bases or alkaline solutions (i.e. bleach ammonia) have values greater than 7, acidic solution (i.e. battery acid, lemon and juice.) each unit change in PH of rain and snow. The principal source of ground water has PH values near 5.6 if it is relatively free of 23 pollution. However, in many areas of the united State, acid rain is now the norm pollution because of pollution emission from sources such as coal fired power plants and car exhaust. Acid rain can have PH value near 14. These are concerns that acid rain is having effect on vegetation and aquatic creation. Once on the ground, it affect ground water PH. PH of groundwater will vary depending on the composition of rocks and sediments that surround tower path of the recharge water in filtrating to the groundwater. Groundwater chemistry varies depending on how long the existing groundwater is in contact with particular rock. 2.7 COLOUR DETERMINATION Well water users can sometimes experience odour or staining problems on appliance and laundry. If the odour is a rotten egg associated with the well water, it shows that a hydrogen sulphate and methane should be analyzed. If there is a musty or muddy odour with well water, an iron bacterium should be analyzed. If there is a problem with black staining of white laundry, the well must be checked for magnesium. Then the analysis of the test 24 must be compared against (EPA) or state drinking regulations to see if any contamination are exceeding recommending level. 2.8 TOTAL SUSPENDED SOLID WASTE (TSS)/TOTAL DISSOLVED SOLID WASTE (TDS) Total dissolved solid waste (TDS) is the portion of solid waste in water that can pass through a micron filter. The more minerals dissolved into the water, the higher the total dissolved solid are generally of inferior portability. In drinking water, a limited of 500mg is desirable. Total suspended solid (TSS). This is suspended collard particles in water which will not settle out by gravity. The volume of sludge produced in a treatment plant is directly related to the total suspended solid.(TSS) present in the sewage industrial and storm sewage may contain higher concentration than the domestic sewage. The extent to which treatment plants removes solids, as well as biology oxygen demand determines (MLA STYLE)”suspended solid encyclopedia Britannia 2011 web is June 2011. 25 2.10 TOTAL DISSOLVED SOLID WASTE (TDS) Total dissolved solid waste (TDS) comprises inorganic salts (principally, calcium, magnesium, potassium, sodium, b1, carbonate, chloride and sulphate) and some small amount s of organic matters that are dissolved in water. 2.11 DISSOLVED OXYGEN (DO) Oxygen is more easily dissolved into water with low levels of dissolved or suspended solid. Water with higher amounts of salts such as the ocean (which contains 35 grams of salts for each 1000 grams of water) have low concentration of DO, fresh water lakes, stream and tap water generally contains much less salt, so DO concentrations are higher. As the amount of salt in anybody of water increases the amount of dissolve oxygen decreases. An increase in salt concentration due to evaporation of water from ecosystem tends to reduce the dissolved oxygen available to the ecosystem inhabitants. The amount of groundwater entering a river can influence oxygen levels. Groundwater usually have low 26 concentration of DO. But it is often colder than stream water. Therefore, groundwater mayat first lower the dissolved oxygen concentration. But as groundwater cools the stream or river, the ability of the water to hold oxygen improves. Therefore, water to be used for domestic water supply should not have dissolve oxygen below 3 milligrams per litre (Colorado Department of public Health and Environment Water Quality Control Division, CD PHE-WQCD). 2.12 SOLID WASTE EFFECTS AND CONTROL ON UNDER GROUND WATER Soluble components of solid waste in contact with water change the groundwater quality or indirectly by infiltration contaminated surface water. Solid waste pollutes groundwater thereby affect the hygienic conditions of human beings. According to Noring, 1951, Legrand 1965, the extent of intensely contamination depends on the following factors. 1. Chemical and physical properties of the waste materials. 27 2. Man’s variable pattern of waste disposal and of accidental release contaminants in the ground. 3. Duration and surface size of contact between waste materials and in the saturated and unsaturated zone of the ground varying in time. 4. Behaviour of the contaminants in the surface water and the saturated zone of the ground. 5. Chemical and physical properties of rock environments varying in space. 6. Influences of microorganism in the saturated and unsaturated zone varying in time. 7. Quality of water percolating from surface or from other aquifers of specific character varying in time. 8. Climatic condition varying in time. 9. Hydrological conditions varying in time and space 10. Man’s variable pattern of water development from wells. 28 Besides the chemical and physical properties of waste materials, the position of the water site as to the groundwater table is of greatest importance for the intensity if contamination. The waste is leached to the greatest extent when deposited in the ground water to the least in the case of waste dump above water table. However, the proper sanitary work must be done before the consumption of underground water. It is obvious that leachate infiltration and percolation are the fundamental occurrence of pollution of underground water. In spite of this, refuse should be dumped in accordance with Environmental Protection agency’ rule and regulations. 2.13 TREATMENTS AND MANAGEMENT OF WASTES Treatment and management of waste including prevention, minimization, recycling, energy recovery and disposal, managing, monitoring of waste materials. The term usually relates to materials produced by human activity and the process is generally undertaken to reduce their effect on health, the environment or the aesthetic. Waste is distinct particles from 29 resources recovery which focuses on delaying the rate of consumption of natural resources. The management of waste treats all materials as single class, whether solid, liquid or radioactive substances tried to reduce the harmful environmental effect/impact of each through different method. (Hughes G.M.R.A. London and R.N. Farvolden 1969). Waste management practices differs from developed and under-developed nations for urban and rural areas and for residential and industrial producers. Management for nonhazardous waste, residential and institutional waste in metropolitan areas is usually the responsibility of local government authorities’ management for nonhazardous commercial and industrial waste is usually the responsibility of the generator(P.F Effer 1992, functional element of solid waste management system). Resource recovery is the selective extraction of disposed material for a specific next use such as recycling, composting of energy generation. The aim of resource recovery is to extract the maximum practical benefit from product, delay the consumption of virgin natural resources and to generate the maximum use of waste by using life cycle analysis 30 (LCA) to offer alternative to landfill disposal of discard materials (Har 1-,S.A. 1967)have indicated that administration source, separation andcollection followed re-use and recycling of nonenergy compost fertilizer production of waste fraction via anaerobic digestion to be favoured alternatives to land fill disposal. However, recycling is a source recovery practice that refers to the collection and re-use of the dispose materials as empty beverages containers. The materials from which the items are made can be reprocessed into new product for recycling may be collected separately from general waste using dedicated bins and collection vehicles or sorted directly from mixed waste stream. The most common consumer’s product recycled include aluminum such as beverages cans copper such as wire, old steel, polythene etc. 31 CHAPTER THREE TYPES OF SOLID WASTE AND THEIR EFFECT 3.1 MUNICIPAL SOLID WASTE Municipal waste also called municipality consist of everyday items we use and then throw away(dispose) such as product packaging, grass, clippings, furniture etc. the term municipality solid waste is generally used to describe most of the non-hazardous solid waste from a city, town or village that requires routine collection and transport to a processing or disposal sites. Sources of MSW includes private homes, commercial activities/establishments and institutions as well as industrial facilities. The types and effect that fall under this are; 3.1.1 FOOD WASTE Food waste such as vegetables and meat materials leftover food, eggshell etc. also known as wet garbage is the discharging and potentially usable foods. Both edible and inedible foods may consider garbage and therefore 32 wasted. Edible foods are considered inedible and when their quality deteriorate until they become unhealthy or obnoxious food deterioration occurs from microbial contamination of from rotting, as a consequence of over production storage problems or improper preparations. Food waste also occurs through food use that returns little nutritional value, like over processing and over consumption. 3.1.3 PLASTIC Plastic is a material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are movable and so can be molded into solid objects. Plastic are typically organic polymers of high molecular mass and often contains other substances. They are usually synthetic most commonly derived from petrochemicals. Plastic waste comes about by littering of plastic materials. When littered rain carries plastic waste (because of its light nature) into streams and rivers and through drains. Drains leads to oceans. 33 Careless and improper waste disposal is also a big contribution – illegal dumping of waste adds greatly to the plastic surge in our seas. EFFECTS Plastic pollution from discarded water bathes, polysthene coffee cups grocery bags, synthetic clothing, fiber and other waste, break down into tiny bits or plastic. No bigger than the period at the end of the sentence. Micro plastics have been detected in water around the world including our streams, lake and oceans. Plastic also leached into the water. Degrading the water quality with toxic compounds and end up harming human and animal health. 3.1.4 Tetra TETRA PACK pack is the name of the company which created hygienically, lightweight packaging for liquids. The first became famous with their tetra-hadron shape packaging which was then used for milk to replace grass bottles. Tetra pack is a packaging 34 material used in packaging foods, drinks and is easily identified by the fact that it looks like cardboard packaging but it has a silver inside lining and certain liquid. It is a terrible waste because it is composite. Tetra pack waste is gotten from/when water carries this waste into streams, rivers or lakes. EFFECTS It can expose people to chemical and radioactive hazards. It can also obstruct storm water runoff, resulting into information of stagnant water bodies that become the breeding ground for diseases. It also attracts flies which in turn brings about disease and sickness thereby bringing rise to health problems. 3.2 HAZARDOUS WASTES Hazardous wastes are wastes generated from wide range of activities including manufacturing, forming, water treatment systems, construction, automotive, garages, laboratories, hospitals and other industries. These waste may be liquid, solid, 35 or sludge and contain chemicals, heavy metals radiation and pathogens or other materials. Even households generate hazardous waste from items such as batteries used computers equipment and leftover paints or pesticides. Hazardous wastes are waste that has substantial or potential threats to public health or the environment. Characteristics of hazardous wastes are materials that are known or tested to exhibit one or more of the following hazardous threat. Ignitability Reactivity Corrosiveness Toxicity 3.2.1 ignitable waste These are waste that are burn at relatively low temperature (60 0 c) and are capable of spontaneous combustionduring storage, transport or disposal. 36 Examples and effect of these include 1. Gasoline: Gasoline is a pale brown or pink liquid made from processed crude oil. It evaporates easily. It is very flammable and can form explosive mixtures in the air. Effects When exposed to water, it contaminates groundwater and the air. Breathing small amount of gasoline vapour can lead to nose and throat irritation, headache, dizziness, nausea, vomiting, confusion and headache. When water is contaminated with gasoline end it makes physical contact with the skin, it could lead to rashes, redness and swelling. 2 Alcohol: Alcohols (ethanol or ethyl alcohol) is the ingredient found in beer, wine and spirit that causes drunkenness. Alcohol is found when 37 yeast ferments (breaks down without oxygen) the sugar in grapes beer from the sugar in malted barley (a type of grain). Alcohol has effect on every organ of the body. When water is contaminated with alcohol the oxygen level is being reduced. Effect The oxygen level of water is reduced when water is contaminated, water can have serious effect on the health of an individual. Diseases such as dysentery, hepatitis or other long term effect such as certain types of cancer may also result exposure to polluted water. 3.2.2 REACTIVE WASTE These are waste that have a tendency to react vigorously with air and water and are unstable to shock or heat, generate toxic gases or explode during routine management examples and effects of reactive waste include 38 GUN POWER: This is black powder (explosives) which consist of a mixture of saltpeter (potassium nitrates) sulfur and charcoal. When prepared in roughly the correct proportions (75 percent saltpetre, 15 percent charcoal and 10 percent sulfur). Effect It contains potassium nitrate which when in excess interfere with the ability of the blood to carry oxygen causing headache, fatigue, dizziness and a blue color to the skin and lips. (Methemoglobinemia) higher level can cause trouble in breathing, collapse and even death. Potassium Nitrate may also affect the kidney and cause anemia. It also contains Sulphur which when in excess can lead to diarrhea and dehydration. The charcoal is made up of also leads to colour in waste whereas we know what qualifies water is that it has no colour, odour or taste. 39 GLYCERIN This is a simple polyol compound. It is a colourless, odourless viscous liquid that is sweet testing and non-toxic. Effect When groundwater contain glycerin consumption may cause headache, dizziness, nausea, vomiting and excessive thirst in some individuals. 3.2.3 CORROSIVE WASTE These are waste that comprises of different chemical and toxic substance. These are waste that destroys materials and living tissues by chemical reactions. Examples and effect include. ACID An acid is a chemical substance usually a liquid which contains hydrogen and can react with other substance to form salt. Some 40 acid burn or dissolved over substance that they came into contact with. Acid is a compound having a sour taste and capable of neutralizing alkalis and reddening blue litmus paper, containing hydrogen that can be replaced by a metal and or electropositive group to form a salt, or containing an atom that can accept a pair of electron from a base. Effects When water is contaminated with acid the PH of water can indirectly affects one’s health. Water with acidic PH can corrode, plumbing and leach metal iron, manganese, copper, lead and zinc are commonly found in acidic water. It places adults at risk for health problems, such as cancer, stroke, kidney disease, memorial problem and high blood pressure. Drinking acidic water exposes one’s body to heavy metals and minerals presents in the water. 41 BASE Base is a substance that aqueous solution releases hydrogen (OH.) ions, are slippery to the touch and taste bitter if an alkali changes the colour of indicators e.g. reacts with acid to form salt, promote certain chemical reactions, accept protons from any proton donor etc. Effects The phenomenon of acid precipitation detrimentally affects aquatic ecosystems to a presently unknown degree. Complex geo-chemical processes in soils are important factors determining the quality of percolates which infiltrates down to ground water systems. Elevated base cation and trace metal concentration in ground water may result in corrosive or toxic water quality conditions. Consequent discharge of effected groundwater to surface water bodies result in detrimental effect to water quality and ambient aquatic life. 42 3.2.4 TOXIC WASTE Toxic wastes are waste that result from industrial, chemical and biological processes. Toxins are found in household, office and commercial wastes. These are wastes containing dangerous pathogens such as used syringes. Examples of common products are routinely part of toxic wastes, streams of industrial countries include batteries for electronic devices, pesticides and heavy metals etc. Groundwater are contaminated with uranium and over toxic chemicals and more than 63.5 million metric tons of radioactive waste. These waste are poisonous in small or trace amount. PESTICIDE Pesticides are substance that is meant to control weeds, pests. These pesticides include herbicide, insecticides (which may include insects group regulation termites etc.) 43 In general, pesticides are a chemical or biological agent such as virus, bacterium or fungus that deters, incapacitates, kills or otherwise discourage pests. Effect Poisoning occurs when toxic waste is injected, inhaled or absorbed by the skin. The health effect of the pesticide depends on the chemical characteristic before the 1940’s, most pesticides were compounds of arsenic, mercury, copper or lead. Although, these compounds may have made their way into drinking water, they are not highly soluble and the residue ingested in food were of far greater concern studies of the health effect of pesticides on human focus on two aspects, the acute toxicity or immediate effect resulting from short term exposure and the chronic toxicity/effects exposures. 44 resulting from long term When these toxic acids are found in water it leads to kidney damage or death at higher doses. It is hazardous to human health and also lead to cancer. HEAVY METALS Heavy metals are naturally occurring elements that have a high atomic weight and a density of at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological application have led to their wide distribution in the environment raising concerns about their potential effect on human health and environment. Effect The biological system heavy metals have been reported to affect cellular organelles and components such as cell membrane mitochondrial, lysome, endoplasmic reticulum. It also affects nuclei and some plasmic reticulum. It also affects nuclei and some enzymes involved in metabolism and detoxification. 45 Metal ions have been found to interact with call components such as DNA and nuclear protein causing DNA damage and conformational changes that may lead to cycle modulation. 3.3 INDUSTRIAL WASTE Industrial solid waste is defined as waste that is generated by businesses from an industrial or manufacturing process or waste generated from non-manufacturing activities that are managed as a separate waste stream. Business that utilize manufacturing or industrial processes or that service or commercial establishment are likely producing industrial solidwaste. This is a special classification of nonhazardous waste that requires by state law special evaluation to determine the proper disposal method. These are waste produced by industrial activities which includes any materials that is rendered useless during a manufacturing process such as that of factories industries, mills and mining operations. Examples and effect of these waste include. 46 GRAVEL A gravel is a loose aggregation of rock fragment. Gravel is classified by particle size range and includes size classes from granule to boulder-size fragments. When gravel is disposed in groundwater, it affects the quality of the water. The effect is as follow. Effects Pits and quarries disturb the existing movement of water i.e. surface water and groundwater. They interrupt natural water discharge and can lead to reduced quantity and quality of ground water like drinking water for residents i.e. wide life near or downstream from a quarry site, potential impairment of water quality on the site including harm to the aquifer. The water quality of residential wells close by could be harm. The water level of onsite lakes could reduce detrimentally affecting provincially specific wet lands. It could also lead to loss of habitats 47 CHEMICAL/OIL/SOLVENT When groundwater contains chemicals oil or solvent and it is being dumped in the stream or carried to the stream by movement of water. This chemical also causes reproductive failure in birds and mammals. It could lead to ingestion (inhalation and skin contact resulting in Acute or ionic poisoning). These chemicals include lead which can affect red blood cells by reducing their ability to carry oxygen and shortening their life span. 3.4 AGRICULTURAL WASTE These are waste produced as a result of various agricultural operations. It includes; manure and other waste from farms, poultry houses and slaughter houses, harvest waste, fertilizers run off from fields, pesticides that enter into water, air or soils and salt and silt drained from fields. 48 Examples of these waste includes groundnut shell also known as hemicellulose A1 has been shown to contain residues of xylose and D- give conic acid. Paddy husk This is also known as the rice husk. It is theouter most layer of the paddy grain that is separated from the rice grain during the milling process. Straw of cereals Straw is an agricultural bye product consisting of the dry stalks of cereal plants after the grain and chaff has been removed. It makes up about half of the yield of cereal crop such as barley, oats, rice, rye and wheat. Effect Agricultural waste may expose workers to harmful biological material (biohazards). Storing agricultural waste can lead to 49 multiply the hazard associated with it since stored waste can release harm full gases. Groundnut shell arrests metal ions by forming meta complexes from the water. If more C.N ratio like paddy husk or straw husk it may cause immobilization of nutrients if applied on the field, it effects to ground occupies a large area if not properly disposed. It contaminates groundwater by putting aquatic habitat lives at risk. These little straws are mistaken for food by sea creatures especially whales and cannot be digested. It also causes bloating which is related to gas and it has another side effect that everyone would love to avoid. The same gases cause farting which makes or causes bloating. 50 CHAPTER FOUR RECOMMENDATIONANDCONCLUSION 4.1 RECOMMENDATION From the above findings,the following recommendations are suggested. 1. Appropriate place should be located at the outskirt of the town for refuse disposal. 2. The water supply around the vicinity should be treated at least three times in a year. 3. The regulatory agency should employ a geologist on its staff list. Preferably one trained in the area of hydrology to assist in solid waste site selection within the states. 4. future effect of a particular solid wastes operation. 5. The regulatory agency should not discourage novel method of collecting and treating refuse leachate for certain installations where proper monitoring can be exercised. 51 6. The regulatory agency should encourage the practice of regional or district approaches to solid wastes collection and disposal. Economic incentives should be available to provide funds to make area wide feasibility studies. This approach will reap great benefits in the control of soil waste disposal practice. 52 4.2 CONCLUSION The focus of the study was on the impact of solid waste on the quality of underground water. It is found that with the increase in the population and the rising demands for food and other essentials. There is rise in the amount of waste generated daily by each household and community and these waste are sometimes dumped in water bodies such as streams etc. these wastes are serious hazards and lead to the spread of infectious diseases. The establishment and closure of landfills could pose a potential hazard to ground water, due to leachate, seepage and air quality due to gases released. Unless proper maintenance and management is sustained for a fairly long time, public health maybe compromised as a result. Dumping of solid waste on landfill/underground water could bring above grave consequences by 20 years’ time or before. Clear and decisive actions may be taken to avert costly and environmentally comprising means for disposing of our waste in the future. 53 The chapter three of this study shows the different types of solid waste. What are the alternative for the disposal of these human waste safely? In order to reduce the amount of solid wastes generated and dumped in the water bodies. The recycling of waste should be planned and reinforced. The heterogeneity of the waste makes it even harder for it to be reused as a raw material. To improve this, the separation of wastes in its sources and its’ sorting would be the first step in waste management strategy. 54 CHAPTER FIVE REFERENCES WASTE MANAGEMENT LICENSING REGULATION 1994 UK’S ENVIRONMENT PROTECTION ACT 1990 LEACHING PROPERTIES OF TYPICAL MUNICIPAL REFUSE STATE OF CALIFORNIA LEACHING OF SOLUBLE SALTS AND ALKALIES FROM INCINERATOR ASH DUMPS STATE OF CALIFORNIA (1952) (MLA STYLE) SUSPENDED SOLID ENCYCLOPEDIA BRITANNICA 2011 WEB 13 JUNE 2011 COLORADO DEPARTMENT OF PUBLIC HEALTH ANDENVIRONMENT WATER QUALITY CONTROL DIVISION, CD PHE – WQCD.
