VOC and Hexavalent Chromium Site Successfully Treated With Combined Remedies

Mr. Bruce Bruso, CBA Environmental Services, Inc.


In the 1950s and 60s, the property at 3033 West Walnut Street was being utilized as plating operation for Electro-coatings.  Following shut down of operations, the soils within the area of the operation were found to be contaminated with Hexavalent Chrome and chlorinated VOCs (e.g., PCE, TCE, etc.).  Results of a site characterization indicated approximately 14,400 tons of impacted soil to a depth of 40 feet.  VOC contaminated soils were expected to be less than 7,700 ppm.

The Wisconsin Department of Natural Resources (WDNR) elected to remediate the site under a publicly funded approach.  Two separate bid options were evaluated: 1) Treat metals in-place, Excavate and remove VOC soils as hazardous and incinerate; 2) Treat metals soils in-place and perform in situ hot-air treatment on VOC soils to lower/ eliminate contamination levels to meet a non-hazardous classification for off-site disposal.  In order to meet the State’s treatment level, site soils had to be treated to less than 5 mg/l TCLP, Leachable Chrome, 14 ppm for PCE and 5 ppm for TCE.  Bid option 2 was selected due to cost savings.
