In the hydrologic cycle, water moves by evaporation and transpiration into the Atmosphere evaporation where it comes in contact-ans Ground Water The term refers to water that collects beneath the surface of the earth in porous, permeable, water-bearing geologic formations or aquifers. Surface water 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 Local percolation Sepage pits sepage pits
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 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? 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? Neighborhood pollution Groundwater contamination Surface water pollution What problems are a result of neighborhood pollution? Diseases that can be spread by direct or indirect contact with the standing wastewater.
Ground water that is obtained via a well can be used for Drinking, industrial, or agricultural Water table aquifer vs artesian Water table aquifer - direct contact with either soil or the intermediate belt Artesian aquifer - overlaid by a layer of impervious material that recieves little or no recharge throigh this confining layer Static water level Level at which water stands in a well Two categories of sources of pollutants in surface water Point source pollution Nonpoint source pollution Point source vs non point pollution Point source comes from specific locations through discharge structures (pipes or ditches). Can be monitored, controlled, and inspected
Nonpoint source is intermittent, dispersed flow that escapes from pollution sources with little or no control Groundwater quality is recognized as a minor problem in Texas. False Cesspools and seepage pits are legal systems in Texas and may be installed. False Bore holes and injection wells are legal in Texas and may be installed. False Artesian aquifers can be contaminated by bore holes and injection wells. True In America, laws can be successfully enforced only when the majority of citizens voluntarily comply.
