Ethylene dibromide

Wernersville Muni Water Authority

NOTE: Wernersville Muni Water Authority purchases water from Western Berks Water Authority which is required to test for ethylene dibromide. Sample information shown below was taken by Western Berks Water Authority.

Ethylene dibromide, a likely human carcinogen, was used until 1984 as a gasoline additive and a pesticide. It affects the hormone, reproductive and nervous systems; causes testicular atrophy; and damages the heart, liver and kidneys.

State, National, and Health Guidelines for Drinking Water

EWG Health Guideline: 0.01 ppb

The EWG Health Guideline of 0.01 ppb for ethylene dibromide 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.

EPA Maximum Contaminant
Level (MCL): 0.05 ppb

The legal limit for ethylene dibromide, established in 1991, was based on analytical detection limits at the time that the standard was set. This limit may not fully protect against the risk of cancer due to ethylene dibromide exposure.
