Alta Equipment, located at 3725 Old Highway 27 South, is a commercial property that has been used for light equipment maintenance since 1998 by various companies. In February 2023, a Baseline Environmental Assessment (BEA), was submitted by the current owner where one groundwater sample from a shallow temporary well located in the property’s septic drain field, had concentrations of PFBS above criteria. The highest detection of PFBS was 485 ppt (compared to 420 ppt) and concentrations decrease to 141 ppt at the western, downgradient side of the property. The onsite private drinking water well was non-detect for PFAS. Groundwater was found at 23-28 feet below ground surface. Shallow groundwater (less than 50’) is expected to flow to the west towards Otsego Lake. Otsego Lake is located approximately 550 west of the site. Deeper groundwater (greater than 100’) is expected to flow regionally to the southeast.

The surrounding area is serviced by private drinking water wells. There is currently no municipal water available in the area.
Many of the downgradient private drinking water wells are less than 50 feet deep with a few private drinking water wells deeper than 100 feet. Directly north of the site, is a church with a drinking water well depth of 170 feet.
EGLE, MDHHS, and local health identified 12 properties that are directly downgradient for drinking water sampling. Many of the wells have unknown well depths or are shallow wells. Shallow drinking water wells to the west were sampled out of an abundance of caution. In September 2024, nine drinking water wells directly downgradient of the site were sampled for PFAS. Five results were non-detect for PFAS and four had detections of PFAS below criteria.
MDHHS will continue to evaluate if the drinking water wells need to be resampled. Based on initial drinking water well results that were all below criteria, EGLE did not expand the sampling area.
