Recommended: Effects of groundwater pollution

1. What is a Superfund site? A superfund site is a piece of land that has been determined by the United States as a space that has been contaminated by hazardous waste and recognized by the EPA as a candidate for cleanup because it puts the environment and human’s health at risk. 2. What is the nature of the industry being operated at Koppers? The nature of the industry being operated at Koppers is a superfund site that once was a property where a wood-treating facility operated between 1916 and 2009. It is known as a superfund site due to contamination with wood treating chemicals in site soils and groundwater. 3. Identify the contaminants that are being generated at the site? Some of the contaminants that are being generated at the site …show more content…

What types of approaches are being considered for the cleanup? In 1990 and 2011 there have been numerous approaches considered for cleanup. Some of the approaches that are being considered for the cleanup are digging up contaminated soil from the Koppers area of the site, treating the dug-up contaminated soil, placing institutional controls on the Cabot area of the site, treating groundwater, and sampling groundwater and surface water. 5. Would you consider this to be a point or non-point source of pollution? Why? I would consider this to be a point source because of the groundwater contamination. 6. In 2001 it was assumed that soil contamination at the site would be prevented from leaching into the Floridan Aquifer due to the assumed impenetrable nature of thick clay formations (Miocene clays) located between the soil contamination sources and the deeper Floridan Aquifer. Has this turned out to be true? No, this has not turned out to be true because significant levels of dissolved contaminants moved to the deeper zones of the intermediate Hawthorn Group formation and the Floridan Aquifer. 7. The Floridan Aquifer, serves as the source of drinking water for how many people in Alachua County? The Floridan Aquifer, serves as the source of drinking water for over 175,000 people in Alachua

  • The Lowry Landfill Superfund Site

    2979 Words  | 6 Pages

    The Lowry Landfill Superfund Site is located in Arapahoe County, Colorado, approximately 2 miles east of Aurora. It consists of approximately 507 acres of waste disposal area and is operated by Waste Management of Colorado, Inc. The land surrounding the site consists of native prairie grass and a wetland located along a local creek. Sections around the site are zoned for agricultural use including cattle grazing and non-irrigated wheat farms. 1 The area is home to numerous endangered species including the bald eagle and peregrine falcon. Due to the large amounts of wastes disposed on the site between 1965 and 1980, it became extremely contaminated with a variety of inorganic and organic contaminants. From 1984 to 1993, the EPA oversaw remedial investigation and feasibility studies that were performed by all responsible parties. Since its listing as a superfund site in 1984, multiple remedial actions have been performed in order to rehabilitate the site. These include clay barrier walls around the site, a groundwater collection system, a soil cover for the main landfill, as well as a landfill gas collection system. Groundwater that is collected on the site is treated at an onsite water treatment facility. In 2007, construction began on an onsite gas to energy plant that utilizes the methane produced by the landfill site. The electricity produced by the plant is enough to power 3000 households. 1 Today, use of land and groundwater on and near the site is still restricted by the state of Colorado.1

  • The Florida Everglades

    3829 Words  | 8 Pages

    Maintaining ecological diversity is necessary for the survival of a biological community. In the United States, American citizens are on the verge of irrevocably damaging one of the country's most unique and diverse treasures - the Florida Everglades. This national park is now the only remaining patch of a river that used to span 120 miles from Lake Okeechobee to the Florida Bay. Dikes and levees created by the Army Corps of Engineers in the late 1940's drained this river to reduce flooding and increase useable water for the development of the region. This major diversion of water lead to a trickle down effect causing the continual decline of the environmental state of the Everglades. Since then, debates over the Everglades' future have silently raged on for years about how, why, and when the restoration will begin. This ongoing, but virtually unproductive effort has cost taxpayers a great deal without any apparent benefits. Recently, this debate has been amplified by the voices of the sugar industry in Florida, which was attacked for its major contribution to pollution of the Everglades. Now debates rage on with a new effort called the Restudy. Backed by the Army Corps of Engineers, this effort would change the flow of the Everglades, potentially restoring it into the viable community of life that it used to be. The question now is, will this latest attempt to restore the Everglades ever be realized (thus ending the cyclic Everglades debate) or will it simply add up to one more notch on the bedpost of inadequate and failed attempts to save this national treasure. The world is watching to see how the United States will handle this unprecedented cleanup.

    And last but not least, the water that we use to drink is also being affected. According to the text “Water quality nearly halts Everglades restorations” on page 117 it states, “The concern about the water quality stems from the amount of phosphorous present in the water. Phosphorous is found in fertilizer, decaying soil, and animal waste.” That means the fertilizer from the sugarcane crops is causing toxic water quality. It has an effect on animals because the water they drink can have phosphorous present in the water.

  • The Florida Everglades

    1335 Words  | 3 Pages

    The Everglades, also known as the River of Grass, is one of South Florida's most treasured areas. It is an area still full of wonder and mystery. The Everglades is lined with a specific type of limestone bedrock formed by tiny organisms called byrozoans. These animals, though not related to coral, act like coral by extracting dissolved limestone from the sea water around them and using it to construct protective chambers in which to live. They then attach to various kinds of sea grasses on the ocean floor and coat them as well. Individual chambers combine together to form rock-like structures. Over thousands of years, when South Florida was completely submerged, a vast amount of this limestone combined with other ocean sediments and was laid down over the area now covered by the Everglades. Prior to the draining activities of humans and its use as an agricultural area, the Everglades was flooded about nine to eleven months of the year. It also lost only about 0.03 inches of soil per year. After the drainage the Everglades began losing soil at approximately 1 inch per year. Now, however, it is only losing 0.56 inches per year.

    Florida became a state in 1845 and almost immediately people began proposing to drain the Everglades. In 1848, a government report said that draining the Everglades would be easy, and there would be no bad effect. Canals and dams were dug to control seasonal flooding. Farmers grew vegetables in the rich soil of the drained land, Ranchers had their cattle graze on the dry land, and new railways lines were constructed to connect communities throughout south Florida; but the ecosystem of the Everglades was not suited for either farming or ranching. The natural cycle of dry and wet seasons brought a devastating series of droughts and floods. These had always been a p...

  • The Effects of Global Warming on Wetlands

    Analysis of sites in five coastal states indicate that many marshes and mangrove ecosystems receive adequate mineral sediments to produce enough organic sediment and root material to remain above sea level at the present rate of sea-level rise (1-2 mm per year globally). However, three of the twelve wetlands studied were not keeping pace with the current rate of sea-level rise. If sea-level rise accelerates, some additional sites would also begin to slowly deteriorate and submerge.
