  2. Surface water - Wikipedia

    en.wikipedia.org/wiki/Surface_water

    By reducing ground water pumping, the surface water supplies will be able to maintain their levels, as they recharge from direct precipitation, surface runoff, etc. It is recorded by the Environmental Protection Agency (EPA), that approximately 68 percent of water provided to communities in the United States comes from surface water.

  3. Water positive - Wikipedia

    en.wikipedia.org/wiki/Water_positive

    Water positive is the concept of water conservation by a company, community, or individual that actively contributes to the sustainable management and restoration of water resources. This involves implementing practices and technologies that reduce water consumption , improve water quality , and enhance water availability .

  4. Water resources - Wikipedia

    en.wikipedia.org/wiki/Water_resources

    Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. These resources can be either freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water or desalinated water (). 97% of the water on Earth is salt water and only three percent is fresh ...

  5. Water quality - Wikipedia

    en.wikipedia.org/wiki/Water_quality

    Environmental water quality, also called ambient water quality, relates to water bodies such as lakes, rivers, and oceans. [16] Water quality standards for surface waters vary significantly due to different environmental conditions, ecosystems, and intended human uses.

  6. Drinking water - Wikipedia

    en.wikipedia.org/wiki/Drinking_water

    Sources where drinking water is commonly obtained include springs, hyporheic zones and aquifers (groundwater), from rainwater harvesting, surface water (from rivers, streams, glaciers), or desalinated seawater. For these water sources to be consumed safely, they must receive adequate water treatment and meet drinking water quality standards. [5]

  7. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Surface tension prevents the clip from submerging and the water from overflowing the glass edges. Temperature dependence of the surface tension of pure water. Water has an unusually high surface tension of 71.99 mN/m at 25 °C [64] which is caused by the strength of the hydrogen bonding between water molecules. [65] This allows insects to walk ...

  8. Aquifer storage and recovery - Wikipedia

    en.wikipedia.org/wiki/Aquifer_storage_and_recovery

    The first agriculture ASR wells were put into service in Oregon in the autumn of 2006 and have injected well over 3,000 acre-feet (3,700,000 m 3) of water during the winter and spring flood flow times using artificial recharge (AR) of flood water as their water source. This shallow recharged water is then recovered as potable water and injected ...

  9. Groundwater banking - Wikipedia

    en.wikipedia.org/wiki/Groundwater_banking

    In-lieu recharge is the renewable surface water used to irrigate the farmland in place of using regular groundwater. [3] This is helping to save more groundwater because the water stays in the aquifer to be used later. [3] Direct recharge is storing water by allowing it to percolate directly to storage in the groundwater basin. [1]
