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 east at the former Anderson Landfill MPART site, in mid-2024, EGLE sampled three existing monitoring wells for PFAS. Groundwater exceeded criteria for PFOA in one monitoring well, located in the northeast corner of the former quarry. The result was 8.6 ppt PFOA (compared to 8 ppt).
EGLE conducted additional PFAS groundwater investigations from fall 2024 through spring 2026. Groundwater exceeded PFOA and PFOS criteria in three monitoring wells. Results indicate that the northeast corner of the site is now delineated. Monitoring wells in the southwest portion of the site detected PFOS at 18 ppt. These exceedances are delineated by adjacent monitoring wells with PFAS concentrations below criteria.
Based on nearly two years of investigation activities, PFAS concentrations have been delineated across the majority of the site, and all required sampling activities are complete.

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 has been shut off by the DNR. In addition, in 2025 EGLE sampled three drinking water wells at the Maybury Farm that is on land leased from the DNR. The analytical results were non-detect.
