Abstract
The paper reviews the work ?A Civil Action? by Jonathan Harr as a basis for exploring violation of E.P.A. regarding water contamination. It uses the incident of water contamination that took place at Woburn, Massachusetts in the 1960s and 70s as one that serves as a lesson in the prevention of water contamination. It lists the deficiencies responsible for the contamination, such as the lack of laboratory checks, lack of inspections of the land and water, lack of compliance evaluation and inhibited civil action.
From the Paper
""A Civil Action? by Jonathan Harr is a book that brings awareness to communities that might be unaware of the EPA standards against water contamination, and the neglect of concerned authorities allowing industries to carry out their illegal dumping of chemicals in certain areas. The incident of water contamination that took place at Woburn, Massachusetts is one that serves as a lesson in history that should not be repeated. This case of water contamination was believed to be responsible for claiming many lives through leukemia because of a chemical substance (Trichloroethylene) present in the water."

Abstract
This paper discusses the hazardous effects of inadequate methods of solid waste disposal on the environment. The paper emphasizes the urgency of the need to deal with this issue, and describes fecal contamination as the major culprit. The writer illustrates how the lack of modern sanitation facilities and adequate health care in certain areas, are the main cause of fecal contamination.
From the Paper
"Fecal waste may contain an undetermined number of bacteria, viruses, and parasites capable of causing disease in humans and animals. Studies have focused on numbers of indicator bacteria (total coliforms, fecal coliforms, and fecal streptococci) or enteroviruses in feces and leachates, but have not estimated the total pathogen load or identified the major sources of these pathogens. This may be due to lack of detection methods for many of the pathogens in solid waste or leachate as well as potentially low numbers of viable but non-culturable organisms. Fecal waste is a breeding ground for diseases and even the smallest of contaminations can cause a great deal of problems."

From the Paper
"The Deloro Mine, in eastern Ontario, is a significant player whose activities has resulted in both surface and subsurface arsenic contamination of both soil and water, at the mine site, and off-site as well. Gold mining and smelting, with arsenic removal, was established in 1886, at Deloro. The health and safety of Deloro workers was compromised due to high levels of metal in their bodies, specifically lead and arsenic. Environmental problems were also an issue, including the air deposition of arsenic dust. This air deposition contamination was so detrimental that residents were unable to hang out their laundry during smelter operation, for years, because of the stack soot high in metals. In the 1960s, the Ministry of the Environment (MOE) Water Resources Commission found water samples to be high in arsenic. "

Abstract
This paper discusses the problems of the residents of Badger, Wisconsin, who are battling to drink contaminant-free water, trying to avoid poisoned fish in Ballistics Pond, and holding their breath while old ammunition sites are burning dinitrotuluene; and yet the government continues to both push and ignore the very destruction that ails them. The author continues that the Department of Defense is spending money on additional armed submarines to continue polluting the oceans. The paper states that, if the United States government wants more money for defense, it should consider taking up effective listening in regards to what might matter to the people in the world.
From the Paper
"The budget proposal mentioned becomes even more sickening when you explore what has happened in Badger further. Badger citizens cannot even drink their own water. According to The Citizens for Safe Water around Badger, "Late on Wednesday, March 3, the Army received results from monitoring wells sampled during the December 2003 round. Several monitoring wells located along the south boundary of Badger detected DNT in groundwater near the intersection of Keller Road and Highway 78 in Sumpter township. DNT levels were detected at 0.02 and 0.05 ppb (parts per billion). The safe drinking water standard for DNTs is 0.05 ppb." The detection of this cancer - causing agent in the Badger water prompted the military to hurry up and wait. Time has elapsed, dollars have been spent, and there is still no cure."

Abstract
This paper describes undisclosed bottled water contamination in America. The paper reports that most of the bottled water is not frequently checked, and that a small percent of it is unsafe for the public. It illustrates how the American public has been advertised into perceiving that bottled water is pure and clean. The author calls for the labeling of bottled water to disclosing the water source, treatments and other key information.
From the Paper
"According to a four-year scientific study made recently public by Natural Resources Defense Council (NRDC) stated that the sales of bottled water in the United States have been blown up in recent years, mainly as a result of a public awareness of purity driven by advertisements and packaging labels featuring unspoiled glaciers and crystal-clear mountain springs. However, bottled water sold in the United States does not necessarily cleaner or safer than most tap water (NRDC)."

Abstract
This paper examines how a study of Southern California coastal waters in 1999 showed that the waters rarely contain enough bacteria during the summer to make swimmers sick, except at creeks and storm drains that are releasing urban runoff. It looks at how significant portion of coastal water contamination comes from non-point source pollution such as agriculture and urban runoff, faulty septic systems, marinas and recreational boating and habitat degradation. It proposes a study to determine the coliform count in water samples from New Port Beach, California which is considered to be one of the best urban beaches in the United States and provides an analysis of the results.
From the Paper
"Newport Beach is the fifth best urban beach in the United States, according to the Surfrider Foundation report issued in May, 2000 (Mehta, 2000). The city was one of three California communities to make the list as a place where healthy shorelines and urban development coexist. However, Newport Bay suffers from extreme pollution from the Santa Ana River. In January, 2000 Gumbel (2000) reported that all 8 miles of Huntington Beach, a few miles north of Newport Beach, had been closed since the previous summer because the water had shown exceptionally high levels of enterococcus bacteria, indicating fecal contamination. Surfrider Beach in Malibu was plagued at the same time by E. coli bacteria and viruses. The contamination in both cases was attributed to urban runoff."

"Removal of Arsenic Compounds From Waste Water
Land disposal of arsenic containing waste, use of arsenic containing pesticides and ore smelting have resulted in increased environmental levels of arsenic containing compounds. (15, 13) A significant amount of these arsenic containing compounds contaminates waste water. An examination of any process for reducing increased levels of arsenic containing compounds in waste water involves an understanding of the chemistry of dissolved arsenic containing compounds, an effective method for measuring dissolved arsenic compounds, and an efficient system for removal of arsenic containing compounds from waste water. Removal of arsenic containing compounds should be addressed in the context of an integrated waste water management program.
Anderson and Bruland (1) examined the forms that arsenic ..."

From the Paper
"Home may be where the heart is, but it is also where the bacteria are. An American?s home is the most likely place where that person will suffer the effects of food contamination ? although restaurants generate more headlines and more concern for most people. This paper provides a brief overview of the food-borne illnesses that are present in the United States today and how each of these has come to be a threat to the American population.
There are between 20 million and 40 million reported cases of food poisoning annually in this country with the cost in medical bills, lost wages and product recalls as high as $10 billion, according to federal estimates caused by the microbial contamination of such foods as poultry, eggs, dairy and seafood (Puzo, 198, p. 8/2)."

From the Paper
"The purpose of this research is to briefly examine the problem of groundwater contamination. The types (origins) of groundwater contamination are identified; economic and political implications are discussed; and solutions proposed.
TYPES (ORIGINS) OF GROUNDWATER CONTAMINATION
The three primary origins of groundwater contamination are (1) urban living, (2) industrial operations, and (3) agricultural activities. Urban living creates groundwater contamination primarily through the use of water as a medium for carrying sewage effluent, and the subsequent return of the water to the supply pool. Urban living also creates groundwater contamination through automobile and household lawn wastes carried to the supply pool through surface runoff. As urbanization increases,(...)"

Abstract
This paper relates that the negative health effects of lead-contaminated drinking water are significant and occur at very low concentrations. The author points out that the primary source for contamination has been identified as corroding plumbing, which means that almost the whole of the developed world is faced with this danger. The paper urges that samples of real-world concentrations of lead in the drinking water supplies in the developed world should be taken from residential, commercial, industrial, and public buildings. The author suggests that this information should be used to develop public health policies.

From the Paper
"Even at very low levels of lead exposure, individuals can experience measurable and permanent neurological damage. This is especially true for the young. Bryant (2004) contends that children are most susceptible to lead exposure from birth until the age of six. This is consistent with remarks by Watt et al. (1996), who outline the effects of minimal lead exposure to infants via drinking water--from bottle feeding, breast, or directly from the mother's blood before birth. Watt et al. (1996) points out that exposure to low levels of lead in infants has been positively correlated to decreases in intelligence over the course of an individual's life."

Snow Scavenging of Atmospheric Organic Contaminants, 1998.
Analysis of a lab experiment atmospheric organic contaminants.
1,449 words (approx. 5.8 pages), 1 source, $ 48.95
»

Abstract
The purpose of this experiment was to investigate the scavenging of atmospheric organic contaminants from precipitation, specifically snow and rain. The paper also determined and quantified, from scavenging, the amount of polychlorinated biphenyls and polycyclic aromatic hydrocarbons present in snow and rain. Snow scavenging of organic contaminants was being studied because little is known about this phenomenon and a large amount of precipitation, which occurs in North America, occurs in the form of snow. By studying the various precipitation the researchers were able to observe snow scavenging, the gas scavenging abilities of rain and the particle scavenging abilities of both rain and snow.

Abstract
The paper explains that Hudson River has been characterized as one of the country's worst cases of PCB contamination. The author points out that community residents have advanced two primary issues of concerns about the Environmental Protection Agency's (EPA) announced plan to remediate the high concentrations of PCBs in the Hudson by dredging the material from the river: (1) the possible re-suspension of contaminants during dredging and (2) the disposition of dredged PCB-contaminated soil. The paper relates that, despite the glaring need for more research to identify better ways of remediating the affected parts of the Hudson River, the fact remains that the industries, which are primarily responsible for the problem in the first place, continue to stonewall by introducing spurious studies they have funded in an effort to delay or avoid any responsibility. The paper includes a table.

Summary and Conclusion
From the Paper
"Other metals such as barium, chromium, aluminum, lead, and manganese are also being released into the Hudson from runoff and discharges points, and are sometimes found at discernible levels in ambient water quality testing in the lower Hudson. During a 14-year period in the late 20th century, researchers found that (a) lead represented 58.5 percent of violations of Department of Environmental Conservation (DEC) water quality standards for the protection of human and aquatic life, (b) cadmium for 6.1 percent, and mercury for 4.7 percent, out of a total 2,123 water quality violations in the Hudson River."

Abstract
This paper focuses on the damage caused to young children by lead contamination. The paper looks at where and how lead contamination most commonly occurs, which groups are the most vulnerable, and the physiological damage caused by lead poisoning. The paper also outlines what can be done, and, in particular, what parents can do to prevent lead contamination, and the actions government must take to help protect children from lead poisoning.
From the Paper
"Lead is a serious environmental contaminant that puts our most vulnerable citizens -- small children -- at risk. Fortunately it is preventable if parents are diligent about managing potential risks. Lead contamination can also occur in workplaces, but children experience more damage from lead ingestion than adults do. At work led may be in the air or dust. Children sometimes eat paint chips from lead-based paint because the lead makes them taste sweet. They can also breathe dust or get it on their hands and then into their mouths if the soil is contaminated. Lead poisoning can damage the kidneys, the nervous system and even reproductive systems (ATSDR). The EPA, in charge of cleaning up environmentally contaminated sites, reports that over 1,000 of their approximately 1,500 targeted sites have lead as one of the contaminants (ATSDR). In children, some effects of lead poisoning may be permanent, making it vitally important that they be protected."
