Vinyl chloride

Warminster Municipal Authority

Vinyl chloride is a known human carcinogen used for production of polyvinyl chloride (PVC) plastics. Discharges from plastics manufacturing can contaminate drinking water with vinyl chloride. Read More.

Exposure to vinyl chloride increases the risk of cancer and can damage the liver and nervous system. The California public health goal of 0.05 parts per billion, set to protect against cancer, is 40 times lower than the amount allowed by the federal government, which is a Maximum Contaminant Level of 2 parts per billion.

Plastic pipes made of polyvinyl chloride (PVC) and chlorinated PVC (CPVC) are widely used for drinking water distribution lines and internal plumbing, raising concern about vinyl chloride contamination of drinking water. A study published in 2011 by Ryan Walter of Cornell University School of Civil and Environmental Engineering suggested that small amounts of vinyl chloride can leach from PVC pipes. Vinyl chloride can also form in the pipes as a result of water disinfection with chlorine.

In an assessment completed in 2000, California Office of Environmental Health Hazard Assessment stated that drinking water is not a significant source of exposure to vinyl chloride for the general population.

State and national drinking water standards and health guidelines

Health Guideline 0.05 ppb

The health guideline of 0.05 ppb for vinyl chloride 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) 2 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.
