Most of the water taken from these wells are either treated or blended to decrease densities below MCLs, though forty percent of the pollutants are still unregulated for their benchmark transcendences. Densities of naturally occurring pollutants surpass benchmarks three times more often than inorganic pollutants. These high densities were found in both confined and unconfined aquifers. The common finding of man made pollutants in groundwater indicate the susceptibility of water supply aquifers to pollution from human activity. The majority of benchmark transcendences for man made pollutants were in unconfined aquifers.
In 2006, total 1,064 water quality test is done within 146 different river basins. As the result, 619 (58%) were clean from the pollutant, 359 (34%) moderately polluted and the rest 86 (8%) were polluted. The river that located at the upstream were resulted clean, while the river located at the downstream were resulted polluted. As the conclusion, the river at the downstream is not suitable for the human consumption as it harmful. FACTORS OF RIVER POLLUTION The water pollution is believed come from the industrial and domestic sewage, waste from the livestock farm, agro-based and manufacturing industries, road and housing construcrion, logging and deforestration, waste product from the mining activities and the heavy metal from the factories.

Several suggestions mentioned above are inseparable from the monitoring, which suggests that dioxin analysis is the basic link of dioxin pollution prevention. Works Cited Andersen, M. E., Mills, J.

Summerville and Charleston area, South Carolina is unfortunately an area that neglects their water quality. The issue here I am speaking of is water quality in an area with high agricultural needs. 1 According to the Journal of Environmental Research and Public Health (2010), “safe drinking water for all is one of the major challenges of the 21st century. microbiological control of drinking water should be the norm everywhere”. Water quality is also important because many dangerous and deadly diseases are traveled through bodies of water like rivers and streams which I found were 93% affected by pathogens.
One of the major concerns in today’s Agricultural system is the use of water, and the short supply of water. A more immediate problem is nitrate contamination in millions of private well around the country. As one can imagine most of these wells are found on private farms around the United States. Nationally 1.4 million households drink water from private wells with nitrate levels that exceed the federal drinking water standard of 10 parts per million (ppm)( Ready, R., & Henken, K.). There is an estimated damage to a household from drinking water from a nitrate contaminated well to be $635 per year, with a total damage of almost $900 million per year to private well owners (Ready, R., & Henken, K.).
These wastewaters are generated by the equipment cleaning, surface preparation, and the rinsing of a surface after paint removal. Paint-related wastewaters can contain organic solvents, heavy metals, and other toxic materials used in paint formulations, surface preparation, and equipment cleaning. These are just a few of the many types of waste produced during the paint lifecycle (figure 1-2). Because of the Clean Water Act of 1972, most point sources of wastewater that have the potential to be discharged to a waterway require a National Pollutant Discharge Elimination System (NPDES) federal or similar state issued of permit (EPA, 2012). Even with this permit, pretreatment of wastewater, prior to discharge, is generally necessary to keep waste at a legal exposure limit.
The isolation of these bacteria from these rivers may be due to discharging of human and animal wastes to the river. The widespread emergence of antibiotic resistance, particularly multidrug resistance, among bacteria has become one of the most serious challenges in clinical therapy (Baker et al., 2009; Jose, 2012). Environments containing antibiotic residues exert selection pressure and contribute to the appearance of resistant bacteria. In light of the potential health risk, many studies have focused on antibiotic-resistant bacteria from various ecosystems (Reinthaler et al., 2003; Osman et al., 2007; Mesa et al., 2006). In the present study, the isolated bacteria were checked for their antibiotic susceptibility and pattern of resistance to antibiotics such as: Amp, Cip, Te, CRO, Van, Amc, Rd, E, Pen, Oxc and Gen.
About 97% of the water is consumed from the River Nile, and the rest from ground water aquifers (Hopkins and Sohair). The major source of water for the people of Egypt is the Nile River is subject to unsustainably high levels of industrial, domestic and agricultural wastewater pollution. Drinking water should be clear and free from odors and micro organisms. However, the drinking water of Egypt is the opposite of the above mentioned qualities. There are several reasons that are accountable for the pollution of water in Egypt.
Also, recovery leads to discolored local creeks and rivers because of the acidic run-off of these waters (Lecture 3/11/02). Next, these resources must be transported all over the world, where they will go into the preparation and refining stage. During this stage, there is a risk that refuse or sludge will result from coal cleaning parts (Lecture 3/11/02). Also, air and water pollution may result from the process of petroleum refining, which involves the change of the chemical composition of petroleum to produce desirable chemicals and fuels. However, that means that the undesirable results are released to pollute the atmosphere.
