Before and after photos of a remediated propertyNEW! DNREC's Division of Waste & Hazardous Substances' Site Investigation and Restoration Section (SIRS) and the Division of Watershed Stewardship's Watershed Assessment and Management Section (WAMS) have recently completed the Phase II regional environmental study of polychlorinated biphenyls (PCBs) across the State of Delaware.  PCBs are hazardous manmade industrial chemicals that are no longer manufactured in the U.S., but are nevertheless widespread in the environment as a result of past usage, poor disposal practices, and their slow breakdown. This study compiled information on the presence and levels of PCBs at hazardous substances sites across Delaware and then estimated how PCBs at these sites continue to be released to nearby surface waters. More information and the Phase II Report are available here.
