August 9, 2010 - DuPont expects to remove up to 80,000 cubic yards of mercury-laced sediment and soil from Pompton Lake and its shoreline in a project that will take more than four years.
The mercury was deposited into the lake over many decades by the Acid Brook, which runs through DuPont's former munitions factory in Pompton Lakes.
State and federal agencies want DuPont to remove the mercury because it is a toxic metal that can harm humans who eat contaminated fish from the lake. The lake is a popular fishing spot known for its pike, bass and carp.
Pompton Lake, which is ringed by homes, also serves as a backup water supply to reservoirs that provide drinking water to many North Jersey towns. Many residents recall swimming in the lake as children.
