Acid—a substance that has a pH of less than 7, (7 being neutral); can lower the pH value of water or soils to be harmful to growth or crops.
Acre-foot—volume of water required to cover 1 acre of land (43,560 square feet-208' x 208') to a depth of l foot. Equals 325,851 gallons/1,233 cubic meters.
Alkaline—a strongly basic substance (above the pH value of 7.0), can raise the pH value of water or soils to be harmful to growth of crops.
Aquaculture-farming of plants and animals that live in water.
Aquifer
Aqueduct-a pipe, conduit, channel or canal used to transport water, generally by gravity.
Aquifer—a naturally occurring underground layer that contains water, usually occurring in the pore spaces between sands or gravels.
Artesian water-groundwater that is under pressure and rises to the land surface when tapped by a well.
Artificial recharge-water is put back into ground water storage from surface water through man made means.
Coagulate-to gather together or form into a mass or group.
Coliform-type of bacteria whose presence in water may indicate contamination by disease-causing microorganisms; removed by disinfection at treatment plants.
Compliance-meeting all applicable drinking water regulations.
Contaminant-anything present in the environment that could be harmful to human health (including microorganisms, minerals, chemicals).
Condensation-the process of water vapor in the air turning into liquid water, the opposite of evaporation; the water that is condensed.
Flowing Water in Canal
Cubic feet per second (cfs)-rate of the flow (in stream and rivers). Equal to a volume of water one foot high, one foot wide, one foot deep flowing past a point a distance of one foot in one second. (One cfs = 7.48 gallons of water flowing each second) The great floods that took out the Salt River bridge in Tempe (early 1980s) were 100,000 cfs! The every day flow of the Colorado River is about 12,000 cfs. http://water.usgs.gov
