Lavale Sanitary Commission
NOTE: Lavale Sanitary Commission purchases water from City of Cumberland which is required to test for p-dichlorobenzene. Sample information shown below was taken by City of Cumberland.
p-Dichlorobenzene is a carcinogenic insecticide used in mothballs, and added to deodorant blocks made for trash cans and toilets. Long-term exposure can cause liver damage and kidney problems.

ppb = parts per billion
State, National, and Health Guidelines for Drinking Water
EWG Health Guideline: 6 ppb
The EWG Health Guideline of 6 ppb for p-dichlorobenzene 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): 75 ppb
The legal limit for p-dichlorobenzene, established in 1987, was based on toxicity studies conducted in laboratory animals in the 1980s. This limit may not fully protect against the risk of cancer due to p-dichlorobenzene exposure.
