The MEI lagoon spilled into the Wickecheoke Creek when a contractor was installing electrical conduit pipe and de-watered a lagoon, causing an unpermitted discharge of waste materials that were in the lagoon. Sampling of the Creek is being done, upstream and downstream, and at the D&R canal and the Delaware River. The discharge started Tuesday and was stopped Thursday (verified as contained by NJDEP Thurs., Dec, 21). A notice of violation was issued by NJDEP. The NJWSA and D&R Canal Commission have also been involved. MEI handles radioactive substances so radiological testing is being done in the creek, along with metals and other regulated substances. NJDEP says the water cloudiness has cleared.
