Download file to see previous pages In 1981, it was discovered by the New York State Department of Environmental Conservation, that the company was disposing its waste inappropriately, through pouring the waste sludge on the parking lot, while also disposing the solvents into an a drain leading to an abandoned septic system (NPL, 2013). The health department of the state then tested the wells in the vicinity of the company and found them to be contaminated with Trichloroethylene (TCE). The company then installed carbon filters on its well system and those of some neighboring homes, but later closed down in 1985, without fulfilling the requirement for the waste and toxic contaminant cleanup (NPL, 2013). b. How it was contaminated The sludge dumped by this company on the drainage system and parking lot was found to contain a hazardous contaminant called Trichloroethylene (NPL, 2013). The company found its way on the Superfund Site List in December 1982, after having dumped waste products in the form of sludge and solvents on its site, since 1968 to 1981 (NPL, 2013). c. The contaminants of concern Trichloroethylene (TCE) is a colorless liquid that is used as a solvent to remove grease from any metallic components, and is also used as a component in spot removers, paint removers and also adhesives (NPL, 2013). This colorless liquid has a sweet scented smell and is inflammable, and the sweet scent is even projected when the substance is burning. Trichloroethylene as a contaminant dissolves in little water, but remains longer in ground water, especially in the water wells (NPL, 2013). However, considering that it is vaporizable, whenever it comes into the surface of soils or water, the chemical components vaporizes into the air, but it vaporizes slowly from the soil than surface waters, considering that it attaches to particles and can remain there for long. Despite the fact that it does not build-up easily in plants and animals, trichloroethylene sticks to water and soil particles, which eventually causes it to settle down at the lower sediment levels in a water body or a water wells (NPL, 2013). The trichloroethylene exposure can occur through breathing in air that contains the vapors of the chemical, or even through drinking or swimming in the water that is already contaminated by the chemical (NPL, 2013). It can also be contacted through using showering water that is already contaminated with the trichloroethylene chemical component, this time through breathing in the vapors and also through skin contact. The health effects of trichloroethylene on humans depends on the amount that is ether ingested or breathed in. when small amounts of trichloroethylene are breathed in, they may cause the individual to suffer from headaches, dizziness and lung irritations (NPL, 2013). However, when the amount of the trichloroethylene breathed increases, it may cause more fatal health conditions, such as unconsciousness and impaired heart functions and to the extreme, death (NPL, 2013). Additionally, whenever trichloroethylene is breathed for long, notwithstanding that it could be in small amounts, it can easily result to the damage of the nerves, as well as the damage and impairment of the kidney and the liver (NPL, 2013). The same effects of breathing large amounts of trichloroethylene are also felt whenever large amounts of the same chemical compound is ingested through drinking, where impaired heart ...Download file to see next pagesRead More

This is because the firm will enjoy the economies of scale. Secondly, since the products are termed as hazardous and it will be unwise for each site to have its dumping site since this will lead to its distribution all over. I would propose that all waste products to be put together and then disposed into main landfill thus reducing the risk of people to get into contact (Woodard 2001). Bearing in mind that each site will have to pay taxes for waste products and more so the cost and damage to environment the...

Hazardous waste management

...Hazardous Waste Management Hazardous Waste Management The United s’ Environmental Protection Agency [EPA] identifies the process of using, reusing, or reclaiming industrial waste as hazardous waste recycling. It is important to distinguish the process of reclamation from the processes of reusing and using hazardous waste material. In this case, the process of reclamation involves processing of the waste from industries in order to recover a product, from the waste, which can be used in other functions. Simply, reclaiming products from hazardous waste products from industrial facilities is equivalent to regeneration of the waste products. In line with this, it is common place for industries to reclaim, or recover spent solvents... such as...

Contamination and Risk Assessment in Environmental Law

...Contamination and Risk Assessment in Environmental Law There are four basic steps involved in heath risk assessment. They are discussed as follows. Hazard identification is the process of determining the level of harm of a stressor to human health. The analysis involves Toxicokinetics, which refers to how the body absorbs and eliminates a substance, and Toxicodynamics that describes how the body is affected by the chemical substance. The second step is the dose response assessment that is meant to analyze the relationship between the exposure and effect. The potential risk in terms of the likelihood of disease or mortality is accessed. At the third level, the duration and levels of contact with the stressor are examined. Exposure... ...

... the asbestos menace at the Ambler Asbestos Piles site. Burke reports that Asbestos has accumulated at Ambler Asbestos Piles site, especially the Wissahickon Creek towards the end of the 19th century. The accumulation of asbestos was as a result of disposal of asbestos-contaminated wastes by Keasbey and Mattison Co. Later on, Nicolet Inc acquired a part of Keasbey and Mattison Co and continues using the dump site to dispose of asbestos products. The company dealt in manufacturing asbestos building materials, for example, millboard and insulating boilers. Burke asserts that the federal Environmental Protection Company gave orders to the Nicolet Company to stop disposing of the wastes on the site, but the orders had little impact... in...
