| On October 15th, 2024, during quarterly monitoring of previously installed monitoring wells at remediation project # 10268, Wesco field staff discovered a floating layer that appears to be hydrocarbons on top of the groundwater at monitoring well MW-1. The layer was approximately 1.75 feet thick consisting of a clearish light brown apparently hydrocarbon liquid. Wesco bailed the product from the well. Approximately 1.5 gallons of the liquid was bailed from the well until all of the liquid had been removed. The product is stored on site for later disposal. The following day, the well was rechecked and about 2 inches were present in the same well. The product was again removed, about 12 ounces. This product was not present at any of the other site monitoring wells. Wesco collected a sample of for finger print analysis and specific gravity. The discovery was reported on the same day discovered via email to ECMC staff Kris Neidel and Alex Fischer. |
