Another common source of groundwater pollution is sewage, which includes drainage from septic tanks and inadequate or broken sewer lines. Animal sewage, especially from factory-style animal farms, is also a source of groundwater (and river water) pollution. Sewage water contains bacteria, which if untreated can cause waterborne diseases such as typhoid, cholera, and infectious hepatitis. If the contaminated groundwater travels relatively quickly... 

POLLUTION ABSTRACTS 102,000 1970-present CAMBRIDGE SCIENTIFIC ABSTRACTS Covers foreign and domestic reports, journals, contracts, and symposia in the areas of pollution, its sources, and its control. Includes air, water, and land pollution, sewage and water treatment, and legal developments...

Environmental Uses. Next to steel fluxing, environmental uses of lime are the biggest market, accounting for 24% of total lime consumption. These uses include air pollution control, water, sewage, and industrial wastewater treatment, hazardous waste treatment, etc. 

Surface-active substances (SAS) are the most widespread contaminants of sewage and natural waters. They translate in small dispertion condition liquid and firm polluting substances - chlororganic, mineral oils, pesticides. Therefore, the SAS contents determination in water solutions is now one of actual tasks of analytical chemistry. 

Non-ionic surfactants used in detergents, paints, herbicides, pesticides and plastics. Breakdown products, such as nonylphenol and octylphenol, are found in sewage and industrial efffuents Products of combustion of many materials Widely used as plasticisers for PVC. Common environmental pollutants... 

As indicated above, national policies and international conventions have been invoked to curb known, and usually obvious, sources of marine pollution. National legislation is used to control coastal discharges of contaminants. A major problem remains owing to the inadequate treatment of sewage prior to emission from land-based sources. The most important deleterious effects in this case are with respect to microbial water quality. This can have a direct influence on bathing criteria and result in beach closures during contamination episodes. An additional problem from land-based sources pertains to transboundary effects, whereby pollution may inadvertently be exported from one country to another. 

Effluent containing methyl parathion may not be discharged into lakes, streams, ponds, estuaries, oceans, or public waters unless the compound is specifically identified in a National Pollutant Discharge Elimination System (NPDES) permit. Moreover, discharge of effluent that contains methyl parathion is forbidden without prior notice to the sewage treatment plant authority (NPIRS 1986). 

Sewage and organic industrial wastes This type of pollution adversely affects the oxygen content of water (BOD, biological oxygen demand). 

The quantity of materials required to sustain the lifestyle of the developed world is large and increasing. In the 1990s, Germans discovered that they consume about 76 tonnes of solid materials and 60 tonnes of domestic water per capita per annum to support their lifestyle. Only a small fraction of this is retained for any length of time. Most of it results in sewage, solid waste and atmospheric pollution.
