Superfund sites are polluted locations in the United States requiring a long-term response to clean up hazardous material contaminations. Sites include landfills, mines, manufacturing facilities, processing plants where toxic waste has either been improperly managed or dumped.
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 ...
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.
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless".

Soil stabilization is a general term for any physical, chemical, mechanical, biological, or combined method of changing a natural soil to meet an engineering purpose. [1] Improvements include increasing the weight-bearing capabilities, tensile strength, and overall performance of unstable subsoils , sands, and waste materials in order to ...
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 ]
Air pollution is trapped in Louisville's Ohio River Valley location. The city is ranked by Environmental Defense as America's 38th-worst city for air quality. [9] Louisville's lowest solar noon is 28.4 degrees with the shortest daylength being 9 hours and 30 seconds, both occurring from December 17–26.
Groundwater remediation is the process that is used to treat polluted groundwater by removing the pollutants or converting them into harmless products. Groundwater is water present below the ground surface that saturates the pore space in the subsurface.
