CRISIS is the toxic waste cleanup advocacy group of
Bridgewater Township, New Jersey. CRISIS has been providing critical
and technical oversight on behalf of the public (regarding the American
Cyanamid/Pfizer Superfund site) since 1992.
Cyanamid Toxic Waste Site in Bridgewater, NJ, south of train station and west of 287. Raritan River lower right
Impoundments 1+2 south of Conrail and west of 287 (Impoundment 2 is the darker square pool on the left)
Impoundment 2 (pre Flexifloat)
January 2015 highlights
Remediation issues concerning impoundments 1+2
Worst contaminated area (tars with 6% benzene)
Lab + pilot tests completed Q2/14
80 degrees C heating drives off benzene/VOC's for capture
Solidification in a cement possible, but some leaching of VOC's will occur over time
How to scale up this treatment to 4-acres?
Study and approval can take 2 more years
Where to remove treated materials to?
Refused by off-site landfills
Maybe to off-site kilns?
Draft FFS study on OU8 - 2H/2015 possible
Impoundment 2 Flexifloat installed for pilot test. Fall 2013
Impoundment 2 pilot test system. The treatment cell is a customized 7' diameter caisson driven through an opening in the Flexifloat platform (see above) to a depth of about 15'. The contaminated layer (including heavy metals and VOC's) are contained and heated within. The Vapors are treated on site (see below). The results from these test will help inform us how to best proceed. This test will treat just a tiny portion of only impoundment 2. This test was underway the early months of 2014. We are awaiting the results.
This equipment is responsible for removing VOC's and other harmful chemicals from the vapor extracted from Impoundment 2 during the pilot test. It is the part of the system illustrated above.
