Techni-Comp, located at 4152 Dove Road, has been utilized as a composting site for over 20 years. For an unknown number of years, the site accepted solid wastepaper sludge from E.B. Eddy Paper/Domtar Paper Company that contained PFAS.
Groundwater flow is unknown. Historical surface water sampling on and near the property exceeded water quality standards for PFOS and PFOA.
- On March 15 and 16, 2022 DHHS collected drinking water samples from two of the six identified wells. The results were non-detect for PFAS for both residents.
- EGLE will continue to reach out to drinking water well owners to check if they want their water tested for PFAS.
- EGLE will continue to engage with Techni-Comp about their environmental obligations.
Residential Well/Alternate Water
- The St. Clair County Health Department identified six possible drinking water wells nearby. EGLE went door to door, left letters on doors, and called the owners. On March 15 and 16, 2022 DHHS collected drinking water samples from two of the six identified wells. The results were non-detect for PFAS for both residents. Based on the two drinking water results, EGLE and DHHS will not be pursuing any further drinking water sampling.
Upcoming Community Engagement
- None scheduled at this time.
