Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental ...
Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
The EPA started a short-term cleanup in fall of 2011, removing 233 drums of industrial waste and 6,100 gallons of chromium-contaminated water from the site. From 2012 through 2014, the EPA demolished the E.C Electroplating building, and contaminated soils and concrete from the site were excavated and removed.
The EPA's RI report is the most recent and extensive investigation to date, and the site characteristics are based primarily on its findings. The Final RI report of November 1989 contains a detailed description and analysis of contaminants found at the site. [5] The contamination on-site at WDI exists in the soil, groundwater, and subsurface gases.
An ‘Action Plan on Prevention and Control of Soil Pollution’ was created in 2016 detailing requirements, work plan, and goals of the national soil contamination prevention priorities. [ 5 ] In the United States , CERCLA was criticized for lengthy legal proceedings, burdens on small businesses, and lack of involvement from state and local ...
A proportion of contaminated sites are "brownfield sites." In severe cases, brownfield sites may be added to the National Priorities List where they will be subject to the U.S. Environmental Protection Agency's Superfund program. The actual sampling of soil, air, groundwater and/or building materials is typically not conducted during a Phase I ESA.
Alongside municipal and hazardous waste the EPA is in charge of soil conservation. The EPA, often with the help of state partners, manages soil contamination through contaminant sites and facilities. An annual report on the Environment and a Toxics Release Inventory is produced as a result of these efforts.
Point source water pollution is largely regulated through the Clean Water Act, which gives the EPA the authority to set limits on the acceptable amount of pollutants that can be discharged into waters of the United States. The 1972 law also created federal authority for a permit system—NPDES—to enforce the pollution standards.
