The NPL guides the EPA in "determining which sites warrant further investigation" for environmental remediation. [2] As of June 6, 2024 [update] , there were 1,340 Superfund sites in the National Priorities List in the United States. [ 2 ]
A 1,300,000-square-foot (120,000 m 2) complex of mixed residential, office, retail and commercial space is being built on 15 acres (61,000 m 2) of former industrial land in downtown Victoria that was contaminated by lead. 10 tonnes of soil was treated with cement, which was mixed into the soil on site simply by using an excavator bucket. The ...
Superfund is a United States federal environmental remediation program established by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). [1] The program is administered by the Environmental Protection Agency (EPA) and is designed to pay for investigating and cleaning up sites contaminated with hazardous ...
These locations are known as Superfund sites, and are placed on the National Priorities List (NPL). The NPL guides the EPA in "determining which sites warrant further investigation" for environmental remediation. [2] As of May 1, 2010, there were eighteen Superfund sites on the National Priorities List in Colorado. [2]
Deep soil mixing requires specialized auger mixing equipment. In order to apply this method in-situ and in deep soil, the oxidant must be pumped to the point of mixing using a kelly bar (a piece of earth drilling equipment), or appropriate piping to the place where the soil needs to be oxidized. The soil then has to be mixed by using mixing blades.
Environmental remediation is the cleanup of hazardous substances dealing with the removal, treatment and containment of pollution or contaminants from environmental media such as soil, groundwater, sediment. [1] Remediation may be required by regulations before development of land revitalization projects.
Landfarming is an ex situ waste treatment process that is performed in the upper soil zone or in biotreatment cells. Contaminated soils , sediments , or sludges are transported to the landfarming site, mixed into the soil surface and periodically turned over ( tilled ) to aerate the mixture. [ 1 ]
In situ is a term utilized within a variety of fields meaning "on site" and refers to the location of an event. [2] Within the context of bioremediation, in situ indicates that the location of the bioremediation has occurred at the site of contamination without the translocation of the polluted materials.
