Surface Water Contaminants

Although drinking water is not yet known to have been affected, the groundwater was contaminated with volatile organic compounds and heavy metals (5). Both of these types of contaminants have been linked with one or several of the following: cancer, liver, kidney, and nervous system problems (4). In July 1979, the State Court required that all material be removed from the site by July 1980 (5). The state has spent over $300,000 cleaning this site (5). According to EPA standards, this site is in the "construction completed" stage of clean up. This does not mean, however that actual cleanup is complete because groundwater may need to be treated more than 30 years before contaminants are at accepted levels (5).

The local area is City of Lake County is acceptable to many Floridians the state’s with fourth largest lake known for bass fishery with many lake beaches for recreational interests such as swimming, boating, and water skiing. The government established the Safe Drinking Water Act of 1986. Environmental Protection Agency (EPA) is required to set standards for drinking water quality as well of oversee all states, localities, and water suppliers who implement these standards. Lake County Florida there is many homes that rely on city ground water while others may have a well system in place. Contamination have impacted to the lakes over many decades led the lake to be

My hypothesis was supported because there were some contaminants that were visible and there were some that were not visible. One of the contaminants that was visible with sample c was copper which was orange. Copper is an orange/red metal and it can be found in small amounts (less than 1 parts per million) in natural, ground, and surface water. However, elevated amounts may occur if corrosive water completely gets dissolved with copper water. This will only happen if corrosive water stays unmoving with copper water for six or more hours which will likely make the water more unsafe for drinking. It will be more unsafe for drinking because it can give a bitter taste and can cause discoloration in the water. Copper is also a contaminant that

These contaminations of the areas were discovered in 1981. The public wells draws water from Olean creek, and they were constructed in the 1970s to relieve the situation of water shortage for a surface water treatment plant. However, excessive leaves of trichloroethylene (TCE) were discovered in public wells in late 1980, and so the use of the wells was discontinued. Some suspected contaminations have been identified. After a supplemental RI/FS study to investigated thirteen properties for the presence of contamination at four of the properties as the main sources of VOC and TCE contamination to the former Loohn’s Dry cleans.

In 1979, Paul and John Reardon purchased 16 acres of land located next to a manufacturing plant in Massachusetts. In 1983, a state environmental agency, responding to a citizen's report, tested soil samples from both properties and discovered extremely high levels of polychlorinated biphenyls (PCBs) on the plant site and on the Reardons' property where it bordered the site. Shortly thereafter, the Environmental Protection Agency (EPA) cleaned up the contaminated areas. In 1985, the EPA notified the Reardons that they might be liable for clean-up costs. An EPA investigation of the property in 1987 revealed that some

In this experiment we tested ground water contaminants. The materials that were used was eight 250mL beakers, three wooden stir sticks, 100mL graduated cylinder, 10mL of vegetable oil, 10mL of vinegar, 10mL of liquid laundry detergent, 100mL beaker, 240mL of soil, funnel, cheesecloth, and water.

“Eighty-six percent of water bottles end up in landfills or in the ocean” (Sexton & Morley). The National Resource Defense Council (NRDC) tested over 1,000 bottles of water to find out what kind of water was really in the bottle (Jemmott). They found out that an estimated 25% or more of bottled water is really just tap water in a bottle (Olson). It is sometimes treated more, sometimes not. Also the NRDC tested water for contaminants. Most didn’t have any but 22% of the brands contained chemical contaminants (Olson). Most of these chemicals were strict above the state health limits. If the water inside the bottle becomes contaminated the producers don’t have to let the consumers know. Although many people believe plastic bottles are convenient, nevertheless they can extremely harm you because of the chemicals in the plastic and is also causing harm to the earth.

Experiments were done on the water quality and the contamination of groundwater. First, I observed the effects that different pollutants had on groundwater. I predicted that the experiments with the oil and vinegar would create the most contaminations to the water. When the laundry detergent were mixed with the groundwater, it created a light green color with a pleasant smell. The second water treatment experiment were about filtering techniques to remove contaminants from water. I predicted to drain the water by removing all the contaminants

The clean up phase of the railroad avenue site has used solvent flushing for enhanced in-situ bioremediation in hot spot PCE zones and dissolved-phase plume. The site is also monitored at least

To develop a better understanding of water contamination, a field comparison between two separate water sources was conducted. The first water sample was gathered from the Simmons Park Pond and the second from a NES water fountain. The data gathered from this experiment was used to answer several questions regarding the prevalence of contamination in nearby water sources. The field analysis ultimately concluded what contaminants had the greatest prevalence, thereby exemplifying the defining differences between the two water sources.

Water pollution has been a growing concern in the United States, from the BP oil spill to the Flint water crisis, because of the adverse effects it can have on the environment and the health effects in humans and animals. Polychlorinated biphenyls, or PCBs, were used widely as coolants and lubricants in transformers, capacitors, and other electrical equipment. The manufacture of PCBs stopped in the United States in October 1977 because of evidence that PCBs accumulate in the environment and may cause health hazards for humans. This research paper will attempt to discuss the dumping of PCBs into the Hudson River by General Electric, the health effects, and the NYS Department of Health and the US EPA’s involvement for the cleanup and restoration.

Salmon populations have been declining for years, especially very drastically in the last few years. This issue has been going on for years with very little awareness of the public living in the Northwest, especially around the Puget Sound area in Washington State. From Seattle Times I quote, “There used to be coho salmon runs all through Puget Sound and creeks. There haven’t been for decades,” said Julann Spromberg, a toxicologist working for NOAA Fisheries. “They’re coming back, and they’re dying. We need to figure out what’s going on.”

Domestic wells are usually shallower than public wells and are more susceptible to contamination from surface waters (Kumar et al., 2010). From 1971-2008, private wells were responsible for 67 percent (n=40) of reported outbreaks from groundwater (Wallender et al., 2013). Contamination of the groundwater that feeds drinking water wells results from infiltration from rivers, septic tank leach fields, and leaking sewer lines (all sewer lines leak). Cross contamination with septic system wastes due to poor design, maintenance or improper spacing is listed as the primary cause. Contamination of groundwater is reportedly widespread (Auld et al., 2004; Curriero et al., 2001; Fong et al., 2007; Thomas et al., 2006; Tornevi et al., 2015) and

“Without water, life would not exist.” This is a quote taken from Water.org. However, it needs a little clarification, Without clean water, life will not exist for long. There are many countries today that do not have access to clean water. This necessity we the people of the United States of America take for granted is not a normal occurrence in every country. With this paper we will look at five different countries with the most polluted water in the world. We will see what is being done to help reduce the water pollution and how the water pollution is effecting the economy is these countries.

Few people give much thought to what’s in the water that comes out of their faucets until a funny smell or color alerts them that more than just water is coming from the tap.
