The Hagen Farm Superfund Site is Used for Agricultural Needs

The EPA agreed to clean up Nahant Marsh in 1999. It was estimated that the clean up would cost $2,000,000. The water level had to be lowered to remove lead pellets so a pipe was used to drain the marsh until a pump was required. Once the water level was low enough they brought in an excavator and excavated and hauled the soil to a stockpile area where it dried out and was hauled to the landfill. In order to render the metal insoluble found in the soil a phosphate-based stabilization chemical was mixed into the soil. After the soil was treated it was removed and then the ground was graded and smoothed so grasses could be

The water and soil contamination is a result of Green Monster, Inc. was a result of gross mismanagement. Of the 551 barrels of benzene waste taken in by Green Monster, 549 were unaccounted for leaving uncertainty of disposal. In 1973 10,000 gallons of benzene containing soil was improperly disposed of by moving to a nearby unlined lagoon. Before closing workers noted repeated spills in the closed loop benzene processing line due to inadequate maintenance.

The southern portion is being cleaned up by the Air Force under Superfund. The reason the northern portion of the base is being clean up under the Safe Drinking Water Act is because it is currently still being used for training by the Army. The Air Force no longer uses the southern portion for training purposes. There are 10 major plumes of concern. Each site has been contaminated by chemical/fuel spills, fire training activities, landfills, and drainage structures.

The Tar Creek Superfund Site is part of Oklahoma, Kansas, and Missouri. The Tar Creek area is where lead and zinc were mined from 1900’s to the 1960’s. When the mining came to a halt over 500 million pounds of toxic waste was left over. This waste, called chat, has caused elevated blood lead concentrations in as high as 43% in some children. When the mines were abandoned they soon flooded. This resulted in contaminated ground water, surface water, and soil. In 1983, the site was put on the National Priorities List Sites. The Tar Creek area has been on the National Priorities List for 20 years and has a rating of 58.15. Cleanup of the site has occurred since the 1980’s and is still in progress today as various organizations such as the DEQ and

The Tar Creek Superfund site was once a large mining operation. The mine started in the early 1900s and was still in use until as late as the 1970s. The area was mostly minded for zinc ore and lead (Wilson). Many of the mines at this site had their own mills for the mineral separation process. Milling the lead and zinc ore created a large amount of waste. This wasted was in the form of gravel, dust, and debris. The milling process also created another type of waste know as mine tailings. Mine tailings also known as “chat”, are huge piles of pulverized rock that are left over after the target metals have been extracted from the mineral rocks that they are located in (Wilson). This separation was largely inefficient, especially in older mining operations. The result after this process left some of the metal-containing mineral left behind creating large above ground piles or being filled in pits are tailings ponds. A few of these above ground piles reached a height of 200 feet, containing high levels of lead and other dangerous substances. When mining came to an end, these huge piles of

Throughout the operation and dismantling of the refinery, various types of wastes including cloth filters, fuller 's earth, oil sludge, contaminated soil, pesticides, heavy metals, and fly ash were generated and disposed of in two on-site landfills adjacent to the Genesee River over a 30-year period. The landfill area of the site consisted of a 9-acre Central Elevated Landfill Area, a 2-acre South Landfill Area, and a 1-acre sand and gravel area between the two landfills. The landfill area was located at the very southern end of

The purpose of the landfill was to bury the large amount of contaminated the soil with toxic Polychlorinated biphenyl (PCB), a class of chemicals so toxic that Congress banned production later. The whole story began in 1973 when Ward PCB Transformers Company dumped more than 30,000 gallons of PCB-contaminated oil on the side of state roads in 14 North Carolina counties. The trucker, who was responsible for taking the oil to a facility to be recycled, disposed of it discreetly and illegally. The person in charge of the company and the trucker was sent to jail for a short time for their negligence on the matter. Contaminants left in the truck and factory was detoxified. However, the area around the factory as well as the lakes and rivers close to the road had been polluted. As a result, more than 60,000 tons of oils were polluted with toxic PCB.

The Tar Creek Superfund Project is located in northeastern Oklahoma. It covers parts of Picher, Cardin, Quapaw, North Miami, and Commerce (4). Picher was a small town with a population of around 20,000 people (6). Tar Creek is slowly bringing the town of Picher to its knees. During the 1990’s a study found that the

In order to understand the goals of the Landfill to Landscape competition, it is necessary to explore how Fresh Kills became known worldwide as the World’s Largest Landfill in the first place. For millennia, Fresh Kills was as salt marsh bordered by the Arthur Kill, the waterway separating Staten Island from New Jersey. Though the

On the shores of Lake Union opposite downtown Seattle, Gas Works Park was built on the location of a former coal gasification plant. The 19-acre site was acquired by the City for parkland in 1965. Opened to the public ten years later, the park, with its Great Earth Mound summit (constructed from on-site excavated material), was designed for passive uses such as strolling or flying a kite, and community gatherings at various scales. The site offers unrivaled panoramic views of the lake and downtown skyline. The park’s designer, landscape architect Richard Haag, has described his work there as “thinning the forest,” a reflection of how he edited the conglomeration of industrial towers, stacks, pipes, and sheds. A central feature, the boiler house,

In the 1920’s, the city bought the land at public auction, which became the municipal and chemical disposal site. (Beck) The city of Niagara Falls and The United States also participated in dumping garbage, military warfare material, and Manhattan Project. This was a disposal site for more than twenty years, until Hooker Chemical Company purchased the site for their chemical disposal. (Beck) In 1953, the Hooker Chemical Company filled the canal with twenty-two thousand tons of waste in barrels, which leaked, broke apart when being dump, and poured into the soil. (Gibbs) In addition, to avoid contaminants leaked to the top layer soil they would cover them up with cinders, ash, clay or loom to decrease the spill. (Gibbs)

The Environmental Protection Agency defines contaminated lands as sites polluted by hazardous wastes and materials that have been unwarrantedly handled, sites containing toxic materials that may have been deposited due to terrorist acts or natural disasters, or sites that contain hazardous materials that are the result of accidents or incorrect handling (EPA).

Transport of contaminated sediments from major regional Superfund projects in the NY/NJ harbor corridor has been the preferred back-end alternative after the dredging remedy is performed in order to clean these areas without generating higher costs. However, after dewatering, these sediments are shipped at great distances (to UT, OK, TX, ID) for final disposition at C landfills or for incineration. Corporate risk management in mishandling the Superfund sediment in transport such as a derailment can lead to long-term corporate liability as well as environmental hazards from a spill from both the ecological and human health perspectives. As such, a new localized remediation method involving superheating sediments on-site within a rotary kiln have recently been implemented in other areas, and, because of its beneficial use product generation, reduction of risk and gaseous contaminants, and removal of transport costs, it is now being considered as a viable alternative to traditional post-dredge remediation procedures.

Developing means of farming agriculture is the reasons humans live in the world they do today. Modern agricultural practices have started the process of agriculture pollution. This process causes the degradation of the eco-system, land, and environment due to the day by-products of agriculture. Agriculture pollution in the United States is a serious problem which affects the health and sustainability of our great nation.
