DNREC Public Information Meeting on Nov. 17, 2016
State officials from DNREC and DPH, along with representatives of the City of Newark, with support from the EPA, held a public information meeting on Nov. 17.

A brief presentation on the site was given by DNREC’s Site Investigation & Restoration Section, while Newark officials discussed the ongoing, successful treatment of the public water supply at the city’s South Well Field Treatment Plant, which ensures Newark’s drinking water meets all primary and secondary maximum contaminant levels specified by the Safe Drinking Water Act and DPH’s Office of Drinking Water. DNREC's presentation and handouts from the meeting, as well as additional related information, are available below:
