Status: Unregulated - EPA has not established a maximum legal limit in tapwater for this contaminant. Carbon disulfide is an intermediate in production of rubber, resins, cellophane, adhesives in food packaging, and numerous other chemicals; it was formerly used as fumigant; is a solvent in metal industries; and is used to remove metals from waste water; a natural product of anaerobic biodegradation. Potential health impacts associated with Carbon disulfide include cardiovascular or blood toxicity, developmental toxicity, endocrine toxicity, gastrointestinal or liver toxicity, neurotoxicity, reproductive toxicity, and skin sensitivity. Sources of Carbon disulfide:  | Industry |
An Environmental Working Group analysis of Carbon disulfide tests reported by 4,333 public water suppliers in 11 states shows that between 1998 and 2003, 82 thousand people in 28 communities drank water contaminated with Carbon disulfide. No health-based limit has been established by the federal government.Carbon disulfide remains unregulated in tap water, without a maximum legal limit. Exposure Summary 82,484 | People drinking water contaminated with Carbon disulfide | 28 | Communities served water contaminated with Carbon disulfide |

Next --> Testing Summary for Carbon disulfide Water suppliers report an average of 0.7 Carbon disulfide tests per year. 35,418 water suppliers failed to report
any Carbon disulfide tests at all. | Are tests routinely required for Carbon disulfide by federal law? | No | | Water suppliers reporting tests for Carbon disulfide (1998-2003): | 4,333 of 39,751 | | Average testing rate for water supplier reporting tests (1998-2003): | 0.7 per year |
|
Carbon disulfide Violations Because Carbon disulfide is unregulated in tap water, no violations are
recorded in EPA's violations database, the Safe Drinking Water Information
System. Under the federal tap water law, water suppliers are not required
to routinely test for Carbon disulfide, and any level is legal in tap water.
