North Penn Water Authority

Ethylbenzene, a component of petroleum, is a volatile cancer-causing chemical primarily used for production of plastics and rubber. Ethylbenzene is also released from gasoline fuel emissions. Read More.

In animal studies, exposure to ethylbenzene causes tumors. Ethylbenzene can also damage lungs, liver, kidneys and the nervous system. The International Agency for Research on Cancer classifies ethylbenzene as “possibly carcinogenic to humans.”

State and national drinking water standards and health guidelines

EWG Health Guideline 300 ppb

The EWG Health Guideline of 300 ppb for ethylbenzene 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 harm to internal organs.

EPA Maximum Contaminant
Level (MCL) 700 ppb

The legal limit for ethylbenzene, established in 1991, was based on a toxicity study in laboratory animals conducted in the 1950s.
