EWG's Tap Water Database

Donate

Mercer County Correctional Center

 

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the New Jersey Department of Environmental Protection, as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the EPA (January to March 2017), tap water provided by this water utility was in violation of federal health-based drinking water standards.

  • Bromodichloromethane

    cancer

    Bromodichloromethane, one of the total trihalomethanes (TTHMs), is formed when chlorine or other disinfectants are used to treat drinking water. Bromodichloromethane and other disinfection byproducts increase the risk of cancer and may cause problems during pregnancy. Click here to read more about disinfection byproducts.

  • Radiological contaminants

    cancer

    This utility detected Radium, combined (-226 & -228), Radium-226 & Radium-228.

    Radiological contaminants leach into water from certain minerals and from mining. Drinking water contamination with radioactive substances increases the risk of cancer and may harm fetal development.

  • Total trihalomethanes (TTHMs)

    cancer

    Trihalomethanes are cancer-causing contaminants that form during water treatment with chlorine and other disinfectants. The total trihalomethanes group includes four chemicals: chloroform, bromodichloromethane, dibromochloromethane and bromoform.
