ANSWER✅ Atmosphere
Why is acceptable quality water vital? - ANSWER✅ No resource in Texas or elsewhere is
more valuable than water. Acceptable quality water is not only vital in sustaining human life,
but is also vital in sustaining the natural environment and the economic life of Texas.
Ground water that is obtained via a well can be used for - ANSWER✅ Drinking, industrial,
or agricultural
Water table aquifer vs artesian - ANSWER✅ Water table aquifer - direct contact with
either soil or the intermediate belt
evaporation where it comes in contact - ANSWER✅
Ground Water - ANSWER✅ The term refers to water that collects beneath the surface of
the earth in porous, permeable, water-bearing geologic formations or aquifers.
,Surface water - ANSWER✅ refers to water that is found above ground in containment
areas, such as lakes, rivers, streams, creeks, and reservoirs.
Water table aquifers are recharged by - ANSWER✅ Local percolation
Sepage pits - ANSWER✅
sepage pits - ANSWER✅ Rock-filled or lined pits dug at least 4 feet deep at the end of a
septic tank absorption field system are called
Cess pools - ANSWER✅ Pits constructed in permeable soil with open-jointed material
along the sides to the bottom of the pit that receive a direct discharge of raw wastewater
are called
How are waterborne diseases transmitted? - ANSWER✅ Microorganisms (pathogens) that
live in the intestine are passed in the feces and get into the water supply
What are the three primary routes of contamination for pathogenic microorganisms and
harmful chemicals from on-site sewage systems to our environment? - ANSWER✅
Neighborhood pollution
Groundwater contamination
Surface water pollution
