EGLE conducted a compliance sampling inspection at Arbor Hills Remediation Area (NPDES Permit MI0045713) on March 6–7, 2024. Composite and grab samples were collected from monitoring point 001A (manhole near the facility compositor inlet) and analyzed for suspended solids, nutrients, metals, volatile organic compounds, and semi-volatile organics. Nearly all analytes were non-detect or below regulated limits; PFOS (3.2–3.4 ng/L), PFOA (9.4–15 ng/L), and PFBS (4.3–4.6 ng/L) were detected at low levels, with no permit violations noted.
Key data point: PFOA detected at 15 ng/L and PFOS at 3.4 ng/L in grab samples collected 3/6/2024, both below federal drinking-water standards but present in landfill effluent.
