### water:

Surface water
* All surface water is disinfected, usually with chlorine.
* Most surface water gets evaporation
  - is used to assimilate municipal and industrial waste
* Some surface water absorbs oxygen.
* Some surface water becomes bottoms
  - depth bottoms
  - flows in surfaces
* Some surface water has hollows
  - large hollows
  - waters come from ground water that has leached through soils highly laden with arsenic
* are also critical for recreational and navigational purposes
  - highly alkaline
  - more susceptible to contamination with pathogens than ground waters
  - moved away from the equator and replaced by upwelling waters
  - rare in deserts
  - the most common source where oocysts can be detected
* becomes groundwater when it seeps downward to the saturated zone.
* can contain a number of different bacteria, viruses and parasites
  - take on many forms including rivers, streams, wetlands and lakes
  - vary greatly in the amount of salts that it carries in solution
* comes from streams, rivers, lakes, ponds, and oceans.
* consists of lakes, reservoirs, and rivers.
* contain abundant life.
* contains low concentrations of VOCs
  - sulphates, chlorides, calcium bicarbonate and magnesium bicarbonate
* has an excessive load of faecal coliform bacteria and is costly to treat
  - effluent limitations for temperature, salinity, pH and appearance
* includes both marine and fresh waters, but exempts ground waters
  - lakes, rivers, streams, and ponds
* includes rivers, lakes, and reservoirs
  - ponds, lakes, streams or creeks
* is almost non-existent, and groundwater is often too deep and polluted
  - channeled to the pit floor where it percolates downward
  - classified into five different classes depending on the cleanliness of the water
  - cleaned of particulate matter and purified before it is considered safe to drink
  - consistently a calcium bicarbonate type
* is contaminated with PCBs
  - phenols, VOCs, and heavy metals including cadmium and lead
  - distributed unevenly across Kansas mainly because of the state's climate
  - evaporated from the earth by the energy of the sun
  - exposed to many contaminants
  - in lakes, streams, reservoirs, and surface depressions that capture and hold water
  - limited to potholes in intermittent streams and stock ponds
  - one of many sources for becoming sick from microbiological contamination
  - open to the environment and more susceptible to contamination
  - persistent even in the dry season
  - polluted due to the lack of waste treatment facilities
  - present throughout the year except in years of extreme drought
  - scarce, but there are underground streams and rivers draining into the sea
  - slowed by wind, while deep currents are slowed by friction with the riverbed
  - slowly, but steadily dwindling
* is the main source of supply of drinking water
  - primary source of water, and irrigation is the largest user
  - residue of precipitation and melted snow, called runoff
  - state's major renewable water source
* is the water above ground
  - in streams, lakes, ponds, and rivers
* is the water that is found on the surface of the Earth
  - lies directly on the earth's surface, such as streams and lakes
  - treated by disinfection to remove bacteria
  - used for about half of Alaska's domestic water supply
  - variable across the region depending on storm rainfalls
  - warmed by sunlight
  - warmer than deeper water
  - water from lakes, rivers, streams, ponds and reservoirs
* leaves the Great Basin only by evaporation.
* major source of drinking water for the coastal edges of Michigan.
* make up a significant portion of the water resources of the Chagrin River
  - the majority of the water used for public supply and irrigation
* moves in to replace the sinking water, thus creating a current.
* persists throughout the growing season in most years.
* scarce resource especially in desert environments.
* seeps downward through soil and porous rock until it reaches impermeable rock or clay.
* tend to move from the equator to the poles, warming the air above.
* trickles two kilometers under the earth where it is heated by the earth' s core.
* turns over and mixes with deeper, usually less-oxygenated, water.
