It is a soil fumigant formerly used in American agriculture. In mammals, it causes male sterility at high levels of exposure. After discovery of its deleterious health effects on humans, the compound was banned from use in 1979 by the United States Environmental Protection Agency (EPA). The continuing presence of the chemical as a contaminant in ground water remains a problem for many communities for years after end of use.
