Wauleco has worked closely with the Wisconsin Department of Natural Resources (WDNR) to investigate and clean up the site since the mid-1980s. Over that time, Wauleco has collected nearly 500 soil samples from about 150 soil borings at the site, drilled and sampled more than 70 groundwater monitoring wells, and installed more than 30 groundwater extraction wells to remove groundwater from beneath the site and clean it up.
Though more work remains to be done, the remediation system Wauleco installed at the site has been very successful at recovering contamination.
Wauleco prepares frequent remediation system performance reports for WDNR. We also:
Wauleco constantly explores the latest scientific developments to bring to bear. We use state-of-the-art techniques to evaluate site conditions and how our remediation is progressing. For example, to better understand conditions below the ground—and potential contamination we’ve yet to address—we intentionally froze soil samples as we collected them from below the surface. This freezing technique better preserves the sample for laboratory analysis. We believe this is the first time this freezing technique has been used in Wisconsin.

In addition to our remediation results, Mother Nature demonstrates a remarkable ability to degrade human-made chemicals naturally. PCP also naturally degrades in the environment. More information is provided here.
We’ve completed a study to ensure such degradation is happening at our site, and that the conditions are right for continued natural PCP reduction by microorganisms that naturally live in the soil. The WDNR oversaw this study which consisted of a Work Plan report and a Results report. Read more about the Work Plan report here. Read more about the Results report here. Read the DNR’s letter in response to the Results here.
