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 .
Approximately 20,000 cubic yards of highly acidic oily sludge containing lead, PCBs and PAHs and 22,000 cubic yards of contaminated soil have been neutralized. Other soil in the landfill is contaminated by PCBs and pesticides. Groundwater contamination by lead, arsenic and manganese has been cleaned up. [33] [34] 02/07/1992: 10/14/1992
Soil and water contamination by metals and other contaminants have become a major environmental problem after the industrialization across many parts of the world. [4] As a result, environmental agencies are placed in charge in remediating, monitoring, and mitigating the soil contamination sites. GIS is used to monitor the sites for metal ...
S/S technologies were used to treat a contaminated former wood treating facility in Port Newark, New Jersey. Approximately 8 acres (32,000 m 2) of soil was contaminated by wood with arsenic, chromium, and polycyclic aromatic hydrocarbons. 8% of Portland cement was used by wet weight of contaminated soil. Both in situ and ex situ processes were ...
Soils contaminated by radiological and chemical waste from plutonium manufacture for the Manhattan Project and subsequent activities. Groundwater contaminated by strontium-90, carbon-14, tritium and hexavalent chromium and discharges into the Columbia River, which is the water supply for over 170,000 people. [33] June 24, 1988
Soil acidification is beneficial in the case of alkaline soils, but it degrades land when it lowers crop productivity, soil biological activity and increases soil vulnerability to contamination and erosion. Soils are initially acid and remain such when their parent materials are low in basic cations (calcium, magnesium, potassium and sodium).
Arsenic contamination of soil, sediments, surface water and ground water, including several private wells and one municipal well. Arsenic and lead contamination of soil in residential yards. [14] 03/19/2008: 09/03/2008 – – –
The Contaminated Land Report (CLR) series of documents have been produced by the Department for Environment, Food and Rural Affairs (DEFRA) and the Environment Agency, to provide regulators with "relevant, appropriate, authoritative and scientifically based information and advice on the assessment of risk from contamination in soils".
