ABSTRACT: One of the most significant threats to the health and safety of man is the quantity and quality of the water consumed; and in especially the developing world, inadequate sanitation facilities and shortage of clean water sources is the cause of waterborne diseases and death to millions of people. This study was therefore geared towards understanding the sources and threats to domestic water supply in the city of Owerri and peoples’ preference for different water sources and possible health implications of such choices. A combination of field observation, interview techniques and questionnaire survey was applied in the study. The study concludes that groundwater sources remain the most preferred water source for domestic use in Owerri town while majority of city dwellers prefer satchet or bottled water for drinking purposes. Major threats to water quality included improper waste disposal and management and unsafe water storage/handling processes. It was also realized that, there is little or no treatment of all water sources in Owerri before usage both for drinking and other domestic uses. Recommendations include proper implementation of environmental/water protection laws and edicts, proper monitoring of packaged water production factories and processes by public health officials. Key Words: Water quality; water and sanitation, urban water, Owerri, African cities 1.0: INTRODUCTION: Of the over one billion people living in Africa, about 40 per cent live in urban areas, and by 2050, it is expected that this will triple to 1.23 billion; and 60% of this urban population live in slum conditions [1]. Although there is some improvement in global access to “improved water sources, defined as one that is protected from outside contamination”, runaway urban growth in African cities has equally increased the number of people without adequate access to potable water thereby jeopardizing the struggle to ensure the greater health of African urban dwellers [2]. One of the most significant threats to the health and safety of man is the quantity and quality of the water consumed; and in especially the developing world, including Nigeria, inadequate sanitation facilities and shortage of clean water sources is TLEP Journal Of Multi Discipline in – Science Research Issues 1 IJETR-www.tlepub.org TLEP International Journal Of Environmental Technology Research ISSN 2488-9324(Paper) E-ISSN 2488-9334(Online) Vol. 2. Issue. 1. 2016 the cause of waterborne diseases and death to millions of people. Agglomerations of human populations and activities place a lot of demand and stress on natural space and resources, leading to scarcity, overuse, depletion and or degradation of the quality of the natural environment. The World Health Organization stated that 2.5 billion men, women and children around the world lack access to basic sanitation services. About 1 billion people continue to practice open defecation, while an additional 748 million people do not have ready access to an improved source of drinking-water. Hundreds of millions of people also live without clean water, facilitating the spread of diarrhoeal disease, the second leading cause of death among children less than five years of age. Many other water-borne diseases, such as cholera, typhoid and hepatitis, are prone to explosive outbreaks in third world cities like Owerri with inadequate disease surveillance and health emergency response. Poor sanitation and hygiene also lead to debilitating diseases affecting scores of people, like intestinal worms, blinding trachoma and schistosomiasis ]3]. Rising populations and the effects of climate change will most likely be the major threats to the provision of safe water and adequate sanitation in African cities, and access to clean drinking water and sanitation is very important as it is directly linked to human health and therefore peoples productive capacity; gender and the nutrition of women and as well as their role in collecting water for families and communities [4]. According to Mafuna et al, [5], African governments and public institutions have not been able to match service delivery with rising urban populations leading to net deficits in water and sanitation supplies leading to concomitant rise in disease burden and disaffection among city dwellers. Demand for clean water supply and adequate sanitation is growing due to the increasing population, and in response to the international commitment to meet the Millennium Development Goals. However, access to improved water supply in most African cities range from as low as 17% in Equator town in the Democratic Republic of Congo to 28 per cent in Ibadan Nigeria and 30% in cities in Chad and Burundi [6]. Increasing rates of urbanization and urban population dynamics in Nigeria coupled with high levels of corruption and decaying public institutions has made Nigeria a country with one of the lowest Water and Sanitation coverage rates in the world. Between 1990 and 2006, access to improved water sources stagnated countrywide at 47% but increased to about 54% in 2010; while access to adequate sanitation decreased from 39% in 1990 to 35% in 2010, with a particularly marked decrease in urban areas, as about 47% of Nigerians use shared and other inadequate sanitation facilities. Another 22% out rightly defecated in the open as they have no access to sanitation facilities at all [1]. In the city of Makurdi, the capital of Benue State, Nigeria, only about 25-30% of the population are served by a crumbling network of water facilities and inhabitants fetch raw water in buckets from the polluted Benue River. In 2008, construction of a water treatment plant sponsored by foreingn aid was started but was left unfinished and government officials were unable to account for about 6 million U.S dollars meant for the project [7]. Global threats to water quality especially in urban areas like Owerri may range from over-exploitation from population explosion (population-natural resource imbalance) and/or degradation from anthropogenic pollution emanating from industrial and technological expansion and rabid urbanization. Continuos and indirect discharge of industrial urban sewerage are major sources of pollutants to water resources. According to Kanu and Achi [8], these industrial discharges or wastes include “heavy metals, pesticides, polychlorinated biphenyls (PCBs), dioxins, poly-aromatic hydrocarbons (PAHs), petrochemicals, phernolic compounds and microorganisms”. These wastes are usually discharged into water bodies from untreated effluents and have been found to be carcinogenic while other chemicals constituents have various debilitating effects on the environment and man depending on duration and levels of exposure. Domestic water sources in cities of Nigeria, is faced with a lot of problems, ranging from shortage of supply, pollution, contamination and improper management of its sources due to increase in population, urbanization and industrialization. The need to identify water sources and address the issues that threaten their existence and utility is of urgent importance and this must involve legislations, policies and action in terms of water management plans and programs. A comprehensive water management program must combine a variety of social, treatment and distribution technologies.

Issue. 1. 2016 Social issues involves the acceptability of particular programs such as the Millennium Development Goals; while water treatment is a means to manage water quality. 1.1: Objective of Study: This study was geared towards understanding the sources of domestic water in Owerri Municipal and peoples’ preference of the different water sources and possible threats to water quality in the metropolis. This study is also an attempt to shed light on the ways and means of managing city water supply in Nigeria, including performance of public utilities and challenges to their operations. 2.0: STUDY AREA: Owerri metropolis a rapidly growing urban centre consequent to its designation as the capital of Imo State in 1976 is located on the south Eastern part of Nigeria. Owerri metropolis has an area of about Figure 1: location of study area in the Gulf of Guinea, West Africa 58 square kilometres and is located on latitudes, 50 25’’ 50 23’’ N and 50 32’ 24.42’’ N and longitudes, 60 58’ 50 23’’ E and 70 04’ 07.51’’ E (Fig.1). The topography is fairly low, with comparatively few undulations. The area is well drained by rivers Otamiri, Nworie and the seasonal Okitankwo, an offshoot of the Imo River. These surface water sources also serve as sources of domestic and industrial water supply to the metropolis. Owerri has a mean annual rainfall (also a source of domestic water) of about 2250 -2500mm; mean temperature is 25-270c, relative humidity of about 80%. Owerri has a population of less than 500,000 persons. According to the 2006 National census, Owerri metropolis had a population of 127, 213 inhabitants and from 17, 000 households, including shops and offices [9]. There are various water sources for domestic uses in Owerri. The Otamiri River is the major drainage channel in the metropolis, originating from a forest north of Owerri city and flows southwards through the Owerri metropolis. Its watershed covers about 10,000 km 2 and mostly covered by depleted rainforest vegetation [10]. The Otamiri River is assaulted on different fronts by industrial and commercial activities such as landfills, motor mechanic villages and untreated urban run-off, yet it is used by several TLEP Journal Of Multi Discipline in – Science Research Issues 3 IJETR-www.tlepub.org TLEP International Journal Of Environmental Technology Research ISSN 2488-9324(Paper) E-ISSN 2488-9334(Online) Vol. 2. Issue. 1. 2016 residents of Owerri metropolis for domestic or industrial purposes including laundry and car wash services and also serves recreational and bathing purposes to especially a younger population in the city. Rainwater is also a domestic water source in Owerri metropolis. Its provision is during the raining seasons. Rainwater is collected via house roofs and stored in metal and plastic tanks for immediate and future domestic uses (washing, cooking and sometime drinking). Borehole water is also one of the domestic water sources in Owerri metropolis. The water is sourced from underground aquifers and may be distributed to residents even up to two kilometers from public utility sources. In general terms, boreholes are drilled to a minimum depth of 50 meters or to a depth where there is an adequate supply to meet the users demands and at which point there is perceived lesser risk of contamination. Borehole water can be contaminated when stored/preserved in the tanks through photocatalytic reactions between the stored water and materials used in manufacturing the storage tanks. 3.0: MATERIALS AND METHODS: A combination of interview, field observation and interview-cum-questionnaire techniques were used in data gathering between June 2013 and May 2014. Stratified random sampling was used in selecting the nth house in nth street (using numbers 1-9) for the questionnaire survey for the study. Also, countless interview sessions where held formally and informally with city administrators, dwellers and travellers using on-the spot techniques. One hundred and fifty (150) households were covered in the questionnaire study segment covering thirty (30) households in each of the five sections of the municipality. The entire questionnaires were fully returned. 4.0: RESULTS AND DISCUSSIONS: Respondents were of varied characteristics consisting of about 48% male; 30.1% civil/public servants; 30% businessmen/traders and artisans and 93% literate/semi-literate adult (25years and above) population. Over 36% lived in rented flats, 50% in public yards, and 13% in owner-occupier houses, while less than 1% lived in makeshift or Batcha houses. These findings are similar to the results on housing for the Owerri metropolis from a 2010 study by Ezekwe et al, [11]. 4.1: Sources of Domestic Water in Owerri Munincipality: Table 1, describes responses as to the various sources of domestic water in the study area. From the table, we see that over 99% of inhabitants in the inner city of Owerri depend on groundwater sources from boreholes as a source of domestic water supply. This preference for borehole water stems from the assumed superiority of groundwater quality over other sources of water, as 90% of the population sees borehole water as unpolluted and 72% take same without treatment (Table 2). This thinking is also common among water professionals. According to a famous hydrogeologist in Nigeria, “groundwater has many advantages over surface water in that it is not exposed to contaminants dumped into the latter. It is filtered naturally. Bacteria do not usually thrive deep down in the groundwater environment. The temperature is constant and the density is less subject to changes than that of surface water” [12]. The table also reveals the relatively high performance of the water Board or public utilities in Owerri as over 66% of the populace depends directly or indirectly on them for water supply. However, out of this percentage, only about 11% depend on the utilities fully for domestic water supply while 89% remain uncartered for. The table also reveals the growing importance of sachet water (31%) and push-cart water vendors or Aboki (18%) as sources of water supply to inner city dwellers. This is a common trend in the cities of the developing world especially Nigerian urban centres. In the city of Lagos, Nigeria, households are turning to private shallow hand-dug wells that provide water of dubious quality usually coloured and with a strong smell. Some of these wells dry up especially in the dry season, thereby exacerbating water hunger in the city. Households mostly rely on street water vendors, locally called Mai Ruwa (Aboki in Owerri) who sell water from tanks and plastic containers on push-carts; and also from a thriving market for “sachet water” or “pure water” packaged in polyethylene pouches [13;14]. In Owerri, only 4% of sampled population claimed to be having water supplied regularly from public utilities, while over 19% are not covered at all, more than 76% receive water less than 2 hours in an average day. Also about 44% described TLEP Journal Of Multi Discipline in – Science Research Issues 4 IJETR-www.tlepub.org TLEP International Journal Of Environmental Technology Research ISSN 2488-9324(Paper) E-ISSN 2488-9334(Online) Vol. 2. Issue. 1. 2016 the water supplied as unwholesome in terms of colour, taste or ordour and almost 87% think that the utilities are inefficient. This situation is also similar to what is obtainable in most African cities. Many public utilities in developing countries find themselves locked in a vicious cycle entrenched by poor performance, poor public support and official corruption. Also, in Latin America, the situation is similar where provision of water services is at a low level of equilibrium where low public trust and confidence leads to poor support causing low prices, low quality service, limited service expansion, operational inefficiency and corruption [15]. In most African countries, failure to provide water for 24 hours is common, and as noted by Kimey [16] in his study on Tanzania’s water utilities. On average, most city dwellers received water for 4 to 10 hours per day and the hours of service varied greatly from one residential area to the other. This haphazard service was caused by water demand management problems, power cuts, main pipe bursts and low pumping pressure. Also, a recent study [15] carried out in the city of Harare in Zimbabwe showed similar trends as 54.8% of the resident’s perceived water to be of poor quality and have resorted to household level disinfection methods, drinking water from private boreholes and bottled water. It was also revealed from the data collected in Owerri that about 33.3% and about 2% of the studied population depend on river/stream water for bathing, cooking and washing and for drinking respectively. Inaccessibility to utilities and poverty were cited as reasons for depending on these unwholesome sources of water supply. It is also noteworthy that only about 30% of city dwellers bother to treat their water before consumption (Table 2, 3 and 4). This carries a high risk burden for water borne diseases. The World Health Organization (WHO) had estimated in 2004 that 2.1 millions people die annually from diarrhea and 10% of the population in less developed countries suffer from parasitic worm infections and 80% of all sickness and diseases in less developed countries can be attributed to water borne infection agents and unsafe water and sanitation conditions [17]. It must also be stated that contrary to the belief of the city dwellers of Owerri, groundwater is not immune to contamination and pollution, more so in an environment where there is no proper management of human and animal wastes. The most serious ground water contaminations in terms of human health implications worldwide are pathogenic organisms. Among the most significant water borne disease caused by these pathogenic agents are typhoid, cholera, bacterial and amebic dysentery, polio infections, hepatitis and schistosomiasis [18]. Improper treatment of faecal waste before disposal is a major avenue through which micro-organisms like faecal coliform and other pathogenic micro-organism can be transmitted to ground water system. Other means include leaky soak-away pits and septic tanks and run off from animal feed lot; faeces of warm blooded animal and birds [19; 11]. Another way in which harmful and pollution indicator micro-organisms enter ground water sources is through slime, formed by naturally occurring ground water micro-organisms. The slime or (biofilm) cling to well screens, casings, pipes and pumps. Disturbance during pumping or well maintenance can cause the slime to dislodge, releasing bacteria. Insects also can carry coliform bacteria into a borehole due to improper casing or poor well seal or caps. Unplugged or abandon wells can also allow coliforms access into deeper aquifers [20; 21]. 4.2: Major threats to water Quality: From Table 4, we conclude that the major threats to water quality in the city of Owerri include poor waste management and water storage/handling. These include untreated urban sewage discharges, refuse dumping and oil spillages from machine and mechanic shops. Discharge of untreated waste from drainages into water bodies which may in turn not only pollute the surface water sources but may become sources of polluted recharge to groundwater sources. Water is also contaminated in the process of storage in exposed overhead tanks as stored water may react with PVC materials used in manufacturing the tanks. Also overhead storage tanks when not properly covered and regularly treated poses a major health challenge as they may become breeding grounds for micro-organisms and mosquitoes especially in disused wells or in boreholes with automatic pumps that do not allow for total drainage of tanks. Unhygienic conditions during water bagging processes or possible contamination during collection, transportation and delivery of water by pushcart vendors is also a veritable water quality challenge. A major threat to public health from water sources in Owerri may be the erosion of unwholesome chemicals from plastic containers used in bottled and sachet storage. According to Linebarger [22], Bisphenol-A (BPA) is a common chemical found in plastic water bottles, plastic containers and food storage containers. BPA leaches from the plastics that hold many TLEP Journal Of Multi Discipline in – Science Research Issues 5 IJETR-www.tlepub.org TLEP International Journal Of Environmental Technology Research ISSN 2488-9324(Paper) E-ISSN 2488-9334(Online) Vol. 2. Issue. 1. 2016 of the foods and liquids consumed and in the United States of America, a 2004 study by the America Centre for Disease Control and Prevention confirmed that about ninety-five percent of Americans have BPA in their urine. Once in the bloodstream, BPAs (and other Bisphenols, B-Z) interferes with developmental and sexual hormone systems through estrogenic activity (EA) by mimicking or antagonizing the actions of naturally occurring estrogens. Scientific studies have also linked BPA and BPS to hyperactivity in children, birth defects; low sperm count in males, early onset puberty in females, obesity, breast cancer and diabetes. It seems to be particularly dangerous during pregnancy and child development. It has been noted [23] that there are over a 100 dangerous chemicals having EA which “can leach from plastic products at very low (e.g., nano molar to pico molar) concentrations that individually or in combination can produce adverse effects, especially in foetal to juvenile mammals. This leaching of monomers and additives from a plastic item into its contents is often accelerated if the product is exposed to common-use stresses such as ultraviolet (UV) radiation in sunlight, micro wave radiation, and/or moist heat via boiling or dishwashing. Chemicals having EA typically interact with one or more of the classical nuclear estrogen receptor (ER) sub-types” and “can produce many health-related problems, such as early puberty in females, reduced sperm counts, altered functions of reproductive organs, obesity, altered sex-specific behaviours, and increased rates of some breast, ovarian, testicular, and prostate cancers” [24] Also a study of fifteen brands of bottled water from Canada and forty-eight from Europe revealed that the toxin antimony in bottles made from polyethylene terephthalate leach into the water they contain, and the concentration of this contaminant increased with storage time [25]. Long-term exposures to antimony have been confirmed to potentiate pneumoconiosis and caused altered electrocardiograms, stomach pain, diarrhea, vomiting, and stomach ulcers including an increase in hepatic malfunction and blood changes [26]. 5.0: CONCLUSION AND RECOMMENDATION Groundwater sources remain the most preferred water source in Owerri town just like in cities in most developing countries and major threats to water quality include improper waste disposal and management and water storage/handling processes. This study concludes that the major domestic water source in Owerri Municipal is private boreholes, and public utility sources. Despite the abundant stream/river water and rainfall sources around the city, the inhabitants do not use much of them, because of fear pollution and contamination. While water from rainfall is mainly used for washing purposes and rarely for drinking and cooking, the major drinking water source is sachet and borehole water. It was realized that, there is little or no treatment of all water sources in Owerri before usage both for drinking and other domestic uses. Finally, it is encouraging that only about 3% of the sampled populace think that the problem of water quality protection is to be left to the government alone, although over 60% think that water pollution is not related to disease burden in the city. The following suggestions are hereby forwarded in line with findings of the study: There should be proper monitoring of packaged water production factories and processes by public health officials as this is currently a major source of drinking water in the city. A task force on implementation of environmental/water protection laws and edicts should be set up to regulate the use of water bodies for sinks of urban waste. Adequate funding and rationalization of staffing in the water board is recommended so that savings from this process can be channelled into new and effective technologies for water treatment and adequate safe water delivery system in the city. It is also very pertinent to engage the general masses on the dangers of using untreated water and on the need for the protection of water resources as a common good.
