Background

The former Holloway Sand and Gravel site is located at 50500 8 Mile Road and owned by the city of Novi. Before acquiring the property, Novi conducted a Baseline Environmental Assessment (BEA), which protects the city from being liable for existing contamination. EGLE received the BEA from the city in May 2024 which didn’t include PFAS sampling. Due to PFAS being discovered above criteria immediately to the west at the former Anderson Landfill MPART site, in mid-2024, EGLE sampled three existing monitoring wells for PFAS. Groundwater exceeded groundwater criteria for PFOA in one monitoring well, MW-12, located in the northeast corner of the former quarry. The result was 8.6 ppt PFOA (compared to 8 ppt). In early 2025, EGLE conducted additional groundwater sampling for PFAS. Groundwater exceeds PFOA and PFOS criteria in MW-3 and MW-12. MW-12 (northeast corner) had detections of 10 ppt PFOA and 18 ppt PFOS (compared to 16 ppt). MW-3, located in the southwest portion of the site, had detections of 29 ppt PFOA and 28 ppt PFOS.

Drinking water information

In 2021 and 2022, EGLE sampled drinking water wells in the vicinity of the former Anderson Landfill due to a large dewatering operation occurring nearby and the potential at the time of the landfill containing PFAS. All drinking water well tests were non-detect except for the Oak Trail drinking water well at Maybury State Park, which was taken off-line by the DNR. In addition, in January 2025 EGLE sampled one well at the Maybury Farm that is on land leased from the DNR; that result was non-detect. Two other drinking water wells at the farm that had been taken offline in the winter will be sampled by EGLE in the spring of 2025.
