Watson Township Dump (Watson Township, Allegan County)
EGLE Site Lead: Ray Spaulding, SpauldingR1@Michigan.gov or 517-290-2401. Webpage last updated: February 24, 2020
Background
Recent Accomplishments
- In June 2019, a consultant on behalf of Watson Township, collected four groundwater samples from on-site temporary monitoring wells. The highest PFOS + PFOA groundwater result was 474 ppt.
- In August 2019, EGLE received the results from the June sampling event.
- On September 26, 2019, EGLE, DHHS and Allegan County Health Department held a town hall meeting in Watson Township.
- Based on the elevated PFAS concentrations in the on-site monitoring wells and groundwater flow, EGLE established a circular study area with a radius of one-half mile from the northern end of the property. As of October 8, 2019, a total of 18 drinking water wells had been tested for PFAS. PFAS was not detected in any of the drinking water wells tested to date.
- On November 20, 2019, EGLE sent a compliance communication to Watson Township requesting the township determine the extent of contamination as well as groundwater flow direction.
Next Steps
- EGLE will evaluate the investigation results when they are received from Watson Township.
Residential Well Testing/Alternate Water Information
- EGLE identified approximately 20 drinking water wells within a half mile radius of the former dump. As of October 8, 2019, 18 of the drinking water wells have been tested. No PFAS compounds were detected in 18 drinking wells that were tested.
- The dragstrip has 3 Type II wells, which were sampled on October 4, 2019. No PFAS compounds were detected in the Type II wells.
Upcoming Community Engagement
- None scheduled at this time.

*Groundwater results are compared to EGLE Part 201 Criteria of 70 ppt PFOS+PFOA.
*Surface water samples are compared to Rule 57 non-drinking water values of 12 ppt for PFOS and 12,000 ppt for PFOA.
*Residential well results are compared to the EPA LHA of 70 ppt PFOS+PFOA.
