March 13, 2019, NJDEP announced interim specific ground water quality standards, effective immediately, for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). Information regarding these interim specific ground water quality standards is available through the Division of Water Monitoring and Standards website https://nj.gov/dep/wms/bears/gwqs.htm. The interim specific ground water quality standards became effective upon posting to the "Table of Interim Specific Ground Water Quality Criteria (ISGWQC), Interim PQLs (IPQLs), and Interim Specific Ground Water Quality Standards (ISGWQS) for Constituents in Class II-A Ground Water" located on this website. The interim specific ground water quality standard for both of these contaminants is 0.01 micrograms per liter (ug/L) or 10 parts per trillion (ppt). The Site Remediation and Waste Management Program is implementing these new interim specific ground water quality standards as described on its web page available at http://tinyurl.com/y3u3mc56 At a minimum, the person responsible for conducting the remediation is required to evaluate whether there is the potential that PFOA and/or PFOS may have been manufactured, used, handled, stored, disposed or discharged at the site or area of concern. If the scope of the remediation is for the entire site, then an entire site preliminary assessment is required to be conducted pursuant to the Technical Requirements for Site Remediation at N.J.A.C. 7:26E-3.1. If the scope of the remediation is for one or more specific areas of concern, then the licensed site remediation professional (LSRP) shall use his or her professional judgement to determine what evaluation is necessary. |
