Words can’t hide the truth: PFAS contamination has hit Forest Hills, turning a familiar water source into a source of fear and anger for residents. But here’s the full story, expanded and clarified for newcomers who want to understand what’s happening and what it means for their health and homes.
PFAS: what it is and why it matters
PFAS are synthetic chemicals sometimes called “forever chemicals” because they persist in the environment and human bodies. In Forest Hills, recent tests show elevated PFAS levels in drinking water, prompting state investigators to act. The Michigan Department of Environment, Great Lakes and Energy (EGLE) confirmed Aspenwood Drive as the latest area under active investigation, joining the Hillsboro and Irene zones identified earlier in Cascade Township. The state’s PFAS Action Response Team flagged Aspenwood as an Area of Interest on December 2.
How the issue surfaced
The investigation began when a property transaction prompted independent water testing in June 2025, revealing a PFAS exceedance: PFOA measured at 16 parts per trillion, above the state limit of 8 ppt. What started as a single high reading during a sale quickly expanded into a neighborhood-wide pattern. According to a Forest Hills neighbor and local realtor, Ashley Schaefer, nearly all homes tested high for PFAS, with only about two of thirteen homes testing below the concern threshold. This prompted EGLE to broaden its assessment.
Impact on residents and early responses
Neighbors report a mix of fear and frustration. Schaefer described the sentiment as “terrified and really angry” upon learning that a daily resource—water—could carry health risks. PFAS exposure has been linked to a range of health effects over time, including potential impacts on pregnancy, thyroid function, cholesterol, immune response, and certain cancers, according to state health analyses.
Residents also wrestle with practical questions: Should they boil water or install whole-house systems? How should they inform neighbors? Some families have already installed reverse osmosis units, which reduce PFAS levels but do not eliminate them entirely. Schaefer notes that, while not perfect, such systems offer a viable mitigation path while longer-term solutions are pursued.
Health, housing, and community concerns
From a homeowner perspective, many worry about the value and safety of long-term residence. Schaefer, a realtor by trade, explains that PFAS contamination is not unique to one street or block—it’s a broader issue that, while serious, is technically remediable. The state emphasizes that the issue may involve multiple sources across the broader area and that groundwater flow is not fully understood, complicating pinpointed fixes.
What the state is doing now
EGLE has conducted multiple rounds of sampling—over 50 properties approached and 36 locations tested so far. Results show PFAS exceedances at 17 sites and detections below the threshold at 16 more. Investigations continue to identify potential sources, with the understanding that various consumer, commercial, and industrial products have contributed to PFAS presence in the environment over time.
To expand protection, the state is widening the sampling footprint and has sent access letters to dozens more properties. In the meantime, Michigan is offering facilitated testing for private wells and providing point-of-use filters certified to remove PFAS at no cost to eligible residents through the Michigan Department of Health and Human Services.
What residents can do now
If you live in or near Irene, Hillsboro, Aspenwood, or any PFAS-sampling zone, you’re eligible for state-supported PFAS testing. For private wells outside these areas, testing guidance is available via the Michigan PFAS Action Response Team. In all cases, testing is encouraged, even if your area hasn’t been officially identified yet—the sooner you know, the sooner you can take protective steps.
Long-term solutions on the horizon
EGLE is funding a municipal water extension project in the Irene area, with design complete and construction anticipated to begin in spring 2026. For the broader Hillsboro area, plans involve partnering with Grand Rapids’ Water Department to explore and secure funding for extending municipal water access. Residents like Schaefer hope connecting to a stable, safe municipal water supply will become the preferred long-term outcome, especially for homes relying on private wells.
A path forward and a call for dialogue
The investigation is ongoing, and while a single source hasn’t been identified, the community must stay engaged. Residents should remain informed, get tested, and consider practical mitigation steps to protect families while authorities work toward a definitive solution.
