Perchlorate contamination refers to the presence of perchlorate ions in the environment, primarily in soil and water. Perchlorate is a chemical compound that is a component of many industrial chemicals, including rocket fuel, fireworks, and certain fertilizers. It can also occur naturally in some desert soils.

The primary source of perchlorate contamination in the United States has been linked to the production and testing of solid rocket fuel at military installations and aerospace facilities. Historical practices of disposing of perchlorate-containing waste led to its widespread release into groundwater and surface water. Additionally, agricultural use of perchlorate-containing fertilizers has contributed to contamination in some areas.

Perchlorates are highly soluble in water, which facilitates their movement through soil and into groundwater aquifers. Once in drinking water sources, they can be difficult to remove with conventional water treatment methods.

Exposure to perchlorate can interfere with the thyroid gland's ability to absorb iodine, a crucial element for thyroid hormone production. Thyroid hormones are essential for regulating metabolism, growth, and development, particularly in infants and fetuses. While human health effects from typical environmental exposure levels are still being researched, regulatory bodies have established drinking water guidelines to protect public health. Efforts to remediate perchlorate-contaminated sites are ongoing, involving various treatment technologies to remove or reduce perchlorate concentrations in water and soil.
