Sewage groundwater pollution

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... 

Water is an essential resource for all living species, including man, and it is necessary to analyze a range of natural waters (e.g., seawater, rainwater, surface water, and groundwater), polluted waters (e.g., industrial water and sewage water), and purified waters (e.g., potable water and distilled water). This article presents an overview of sampling and sample treatment procedures and discusses a range of analytical techniques used for the quantification of major, minor, and trace constituents. 

The presence of some surfactants or their by-products in the aquatic environment has been considered as a potential marker of pollution [45, 325]. Thus, the presence of alkylbenzene sulfonates in groundwater has been used as an indicator of the age of the groundwater [358]. Linear alkylbenzenes can act as tracers of domestic waste in the marine environment [34,35,359,360] and trial-kylamines as indicators of urban sewage in sludge, coastal waters, and sediments [17,33,45,325, 327, 346,361]. Analysis, identification, and characterization of surfactants are extensively reviewed and discussed by Aboul-Kassim and Simoneit [314], while pollution problems associated with these compounds are reviewed by Aboul-Kassim and Simoneit [356]. 

Despite the strengthening of environmental policies, problems in relation to cadmium and cyanide, dioxin, organic pollution, lake eutrophication, residential sewage, pesticide runoff, industrial discharges, and groundwater contamination by toxics and nitrates also need to be tackled. 

At the consumer end of the food chain, approximately 3 kg N, 0.5 kg P and 2 kg K per capita and year are consumed by humans. Most of this is converted into human excreta that pollute surface and groundwater due to lack of sanitary and sewage treatment infrastructure. Associated problems of human and ecosystem health are most severe in urban areas, whose population is projected to increase from 285 mio. to 440 mio. until 2020 (UN, 1999).

A freshwater stream may look sparkling and clean, but it s probably not safe for drinking. Many rivers and lakes in the United States are polluted. Bacteria and viruses enter water supplies through contamination by sewage and industrial wastes. Wastes from landfills and mines leak into groundwater reservoirs. Pesticides, herbicides, and fertilizers are picked up by rainwater and carried into streams. Streams flow into rivers, and rivers empty into oceans. In addition, coastal cities pump waste directly into the oceans. For this reason, much of the oceans pollution is found along the coasts of continents. 

Carbonate mineral saturation can limit metal and carbonate concentrations even in sewage and landfill leachate polluted groundwaters. What would you expect the apparent CO2 pressure to be in such waters and why What about the solubility of carbonates under such conditions ... 

Factories have contaminated streams since the dawn of the industrial revolution, and governments have long taken notice. As early as 1901, a survey article could report that the only jurisdictions in the United States that lacked statutes to control water pollution—which was understood to include both industrial waste and sewage—were Louisiana, Arkansas, Texas, South Carolina, and Indian Territory (the future Oklahoma). By 1924, all 48 states had laws that covered industrial waste. Both surface water and groundwater were always understood to be vulnerable to contamination by the mid-nineteenth century, lawsuits over pollution of groundwater were numerous.16...
