New Jersey Department of Environmental Protection (NJDEP) has added a web page dedicated to information on contaminants of emerging concern to its website. The Department defines contaminants of emerging concern as “those chemicals that recently have been shown to occur in water resources and identified as being a potential environmental or public health risk.” More and more such contaminants are being identified as scientists have employed new analytical capabilities that are able to detect chemicals present in the environment in very low concentrations. The definition of “contaminants of emerging concern” will need to be watched closely by LSRPs and remediating parties because NJDEP’s new webpage also provides that “Contaminants of emerging concern, if discharged to the waters or onto lands of the State, are pollutants that must be remediated using a [LSRP]. When the remedial objective for a site is an entire site final remediation document and the site is currently or was formerly occupied by facilities that stored, handled, and used contaminants of emerging concern, LSRPs must consider these contaminants of concern during the investigation and remedial action. LSRPs must evaluate the site for potential spills and releases through air, water, and waste discharges.” To visit the web page, click here.
The New Jersey Department of Environmental Protection (NJDEP) will set formal Maximum Contaminant Levels (MCLs) for perfluoroctoanic acid (PFOA) and perfluorononanoic acid (PFNA). The move, which requires statewide testing of public drinking water systems, is based on the New Jersey Drinking Water Quality Institute’s recommended drinking water standards of 14 parts per trillion for PFOA and 13 parts per trillion for PFNA. Previously, PFOA was subject to a non-binding “guidance level” level of 40 ppt. New Jersey becomes the first state to set MCLs for these contaminants, which, according to a growing body of evidence, may impact liver and immune system function. For the press release, click here.
