VOC and Hexavalent Chromium Site Successfully Treated With Combined Remedies

Presenter:
Mr. Bruce Bruso, CBA Environmental Services, Inc.

Summary:

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.
