Community Update #17 Pompton Lakes Study Area Pompton Lakes, New Jersey Upland Soil Areas Excavation/Dredging Community Update September 2016 EPA CLEANUP ACTIVITIES Basic Site Information The Upland Soil Areas excavation is complete with the exception of one small area (Area Al) totaling ap- proximately 20 cubic yards (CY). Mechanical dredging of approxi- mately 19,300 CY of impacted sedi- ment (containing mercury/lead/other metals) in Area A and the Island Area will begin once an access chan- nel is dredged between the Uplands Soil Areas and Area A/Island Area. Work is being performed by Seven- son Environmental Services, Inc., a contractor for The Chemours Com- pany FC, LLC (Chemours) with EPA/NJDEP oversight.

The shallow depth of the Acid Brook Delta between the Upland Soil Areas and Area A/Island Area necessitated mechanically dredging an access channel to those two areas. Dredging the access channel is underway. The project continues to be on schedule.
