RANDOLPH, NJ- Recently, several news sources have published results of Hexavalent Chromium (Chromium-6) testing, which include results from the Township of Randolph’s Water System.

Chromium-6 levels in drinking water are not currently regulated by the Environmental Protection Agency (EPA), or by the New Jersey Department of Environmental Protection (NJDEP), and regular testing for Chromium-6 is not required. These levels were determined through Unregulated Contaminant Monitoring Rule Testing (UCMR3), which included results from Randolph’s water system.

Randolph’s average level of Chromium-6 is 0.46 parts per billion (ppb).

UCMR3 monitoring was conducted in order to provide a basis for future regulatory actions for public water systems. We anticipate the EPA and NJDEP will evaluate the data from the UCMR3 monitoring to establish new mandatory monitoring requirements for some contaminants, which may include Chromium-6.

In July 2014, the State of California became the first state in the nation to monitor Chromium-6 in drinking water, with a Maximum Contaminant Level (MCL) of 10ppb. California has also established a Public Health Goal of 0.02ppb for Chromium-6.

The average results for Chromium-6 in Randolph’s water are well below the MCL established by the State of California, and slightly above California’s Public Health Goal. A Public Health Goal is not a regulatory requirement, but is instead a non-mandatory level established by a particular agency.

The Township of Randolph purchases all water from the Morris County Municipal Utilities Authority well fields located on Pleasant Hill Road in Randolph Township. As a public water system, Randolph continuously monitors drinking water for the following contaminants to ensure safe drinking water:

  • Total Coliform Bacteria
  • Iron
  • Maganese
  • HAA5 ( Haloacetic Acids)
  • TTHM ( Thrihalomethanes)
  • Lead
  • Copper
  • Asbestos

The Township of Randolph is dedicated to delivering drinking water that meets or exceeds all required State and Federal drinking water standards. The township is committed to providing all residents with the highest quality drinking water.
