  • Total dissolved solids
    Total dissolved solids (TDS) is a measure of the combined content of all inorganic and organic substances contained in a liquid in molecular, ionized or micro-granular (colloidal sol) suspended form.
  • Aquatic ecosystem
    An aquatic ecosystem is an ecosystem in a body of water.
  • Drop (liquid)
    A drop or droplet is a small column of liquid, bounded completely or almost completely by free surfaces.
  • Fountain
    A fountain (from the Latin "fons" (genitive "fontis"), a source or spring) is a piece of architecture which pours water into a basin or jets it into the air to supply drinking water and/or for a decorative or dramatic effect.
  • Fresh water
    Fresh water is naturally occurring water on Earth's surface in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers and streams, and underground as groundwater in aquifers and underground streams.
  • Heavy water
    Heavy water (deuterium oxide, 2H2O) is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium (2H or D, also known as heavy hydrogen), rather than the common hydrogen-1 isotope (1H or H, also called protium) that makes up most of the hydrogen in normal water.
  • Seawater
    Seawater, or salt water, is water from a sea or ocean.
  • Tap water
    Tap water (running water, city water, municipal water, etc.) is water supplied to a tap (valve).
  • Water resources
    Water resources are sources of water that are useful or potentially useful.
  • Aqueduct (bridge)
    Bridges for conveying water, called aqueducts or water bridges are constructed to convey watercourses across gaps such as valleys or ravines.
  • Seiche
    A seiche (/ˈseɪʃ/ SAYSH) is a standing wave in an enclosed or partially enclosed body of water.
  • Hydromancy
    Hydromancy (Ancient Greek ὑδρομαντεία, water-divination, from ὕδωρ, water, and μαντεία, devination ) is a method of divination by means of water, including the color, ebb and flow, or ripples produced by pebbles dropped in a pool.
  • Water activity
    Water activity or aw is the partial vapor pressure of water in a substance divided by the standard state partial vapor pressure of water.
  • Water purification
    Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water.
  • Ion-exchange resin
    An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange.
  • Tritiated water
    Tritiated water is a radioactive form of water where the usual hydrogen atoms are replaced with tritium.
  • Aquaphobia
    Aquaphobia or waterfright is a persistent and abnormal fear of water.
  • Man overboard
    "Man overboard!" is an exclamation given aboard a vessel to indicate that someone (not necessarily a "man" but historically one of the crewmen "manning" the vessel) has fallen off of the ship into the water and is in need of immediate rescue.
  • Malvern water
    Malvern water is a natural spring water from the Malvern Hills on the border of the counties of Herefordshire and Worcestershire in England.
  • Soakage (source of water)
    A soakage, or soak, is a source of water in Australian deserts.
  • Hard water
    Hard water is water that has high mineral content (in contrast with "soft water").
  • Soft water
    Soft water is surface water that contains low concentrations of ions and in particular is low in ions of calcium and magnesium.
  • Electrolysed water
    Electrolysed water (electrolyzed water, EOW, ECA, electrolyzed oxidizing water, electro-activated water or electro-chemically activated water solution) is produced by the electrolysis of ordinary tap water containing dissolved sodium chloride.
  • Water quality
    Water quality refers to the chemical, physical, biological, and radiological characteristics of water.
  • Water efficiency
    Water efficiency is reducing water wastage by measuring the amount of water required for a particular purpose and the amount of water used or delivered.
  • Water content
    Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, fruit, or wood.
  • Extraterrestrial liquid water
    Extraterrestrial liquid water (from the Latin words: extra ["outside of, beyond"] and terrestris ["of or belonging to Earth"]) is water in its liquid state that is found beyond Earth.
  • Roman aqueduct
    The Romans constructed numerous aqueducts in order to bring water from often distant sources into cities and towns, supplying public baths, latrines, fountains and private households.
  • Water use
    Water use can mean the amount of water used by a household or a country, or the amount used for a given task or for the production of a given quantity of some product or crop, or the amount allocated for a particular purpose.
  • TOMA (vehicle)
    TOMA (Turkish: Toplumsal Olaylara Müdahale Aracı, English: Intervention Vehicle to Social Incidents), is an armored water cannon designed for riot control, from a Turkish company, Nurol Makina.
  • Aerated water
    Aerated water is, correctly speaking, water to which air is added.
  • Origin of water on Earth
    The origin of water on Earth, or the reason that there is clearly more liquid water on Earth than on the other rocky planets of the Solar System, is not completely understood.
  • De aquaeductu
    De aquaeductu (English: On aqueducts) is a two-book official report given to the emperor Nerva or Trajan on the state of the aqueducts of Rome, and was written by Julius Sextus Frontinus at the end of the 1st century AD.
