What groundwater sampling has been performed offsite?
In 1991, we installed four offsite groundwater monitoring wells and have been conducting monitoring annually as directed by the NJDEP. Two of these wells showed no evidence of contamination during a three-year period of sampling and were closed in coordination with the NJDEP. The third well, which we continue to monitor, has never shown the presence of TCE or related compounds. The fourth well has shown steady decreasing levels of TCE (160 parts per billion in 1991 to 8.7 parts per billion in August 2008. We continue to monitor these two wells.
