Screening for Mercury at Suspected Contaminated Land Sites

Contaminated land. Land contaminated by previous industrial activities, past military uses and mining operations continue to be a source of concern to communities looking to redevelop brownfield sites, as local authorities struggle to evaluate the risk to health posed from these sites and formulate appropriate remediation plans. In addition to a long list of organic contaminates, such as chlorinated solvents, polyaromatic hydrocarbons (PAHs) and oil residues, soil at many former manufacturing sites have high levels of metals such as arsenic, lead, antimony, chromium, nickel and mercury, which impact drinking water quality.
