Styrene

Status: National drinking water standard exists

 

Styrene is a volatile cancer-causing chemical used for manufacturing Styrofoam (polystyrene) and other plastics. Releases from industrial production sites and hazardous waste landfills cause styrene contamination in drinking water. Read More.

In addition to increasing the risk of cancer, styrene can also damage the liver and the nervous system. California set a public health goal for styrene in drinking water at 0.5 parts per billion. The federal Maximum Contaminant Level (MCL) allows up to 100 parts per billion of styrene in water, which is 200 times more than the California recommended level.

ppb = parts per billion.

EPA Maximum Contaminant
Level (MCL) 100 ppb

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