Carbon tetrachloride

Talbotton

Carbon tetrachloride, a volatile carcinogenic solvent, has been used in industrial chemical production and as a dry cleaning ingredient. Read More.

Carbon tetrachloride is no longer permitted in products intended for home use in the U.S. In the past, it was widely used as a dry cleaning ingredient, fire extinguishing chemical, pesticide and chemical intermediate for manufacturing refrigerants. Carbon tetrachloride does not break down easily and can remain in groundwater for years. In addition to increasing cancer risk, carbon tetrachloride harms the liver and causes central nervous system depression, irregular heart rate, and kidney damage. Maternal exposure to carbon tetrachloride in drinking water has been associated with a risk of birth defects.

ppb = parts per billion.

State and national drinking water standards and health guidelines

Health Guideline 0.1 ppb

The health guideline of 0.1 ppb for carbon tetrachloride was defined by the California Office of Environmental Health Hazard Assessment as a public health goal, the level of a drinking water contaminant that does not pose a significant health risk. This health guideline protects against cancer.

ppb = parts per billion.

EPA Maximum Contaminant
Level (MCL) 5 ppb

The enforceable federal standard that defines the highest level of a contaminant allowed in drinking water.

ppb = parts per billion.

EPA Maximum Contaminant
Level Goal (MCLG)0 ppb

A non-enforceable federal health guideline. For cancer-causing chemicals, these health goals are typically set to zero.

ppb = parts per billion.
