GFL Environmental commissioned a soil remediation evaluation of Pond 2 at Arbor Hills Landfill following removal of contaminated soil containing PFAS (per- and polyfluoroalkyl substances). Six soil samples collected in November 2022 from six locations around the pond bed were analyzed for PFAS and fractional organic carbon (FOC). The analysis found only one sample (Pond 2-East) with detectable PFOS at 180 ng/kg, which remains below the EGLE Part 201 protective criterion of 1,400 ng/kg for drinking water.
Key data point: Pond 2-East soil sample contained PFOS at 180 ng/kg (below EGLE Part 201 limit of 1,400 ng/kg); five other samples showed no detectable PFOA or PFOS.

The facility failed to fully comply with the approved test protocol: turbines shut down unexpectedly on day one with a switchover to diesel fuel (visible black smoke for ~30 minutes), ductburners were not tested despite permit requirement, and only maximum-load testing was performed instead of the federally mandated variable-load testing for NOx.
Key data point: Turbine 1 & 2 abruptly shut down on 10/17/2023 and defaulted to diesel fuel with visible black smoke (approximately 30 minutes duration); potential violation of permit conditions where diesel use is permitted for start-up only. Testing on 10/18–10/19 not fully conducted in accordance with approved protocol (ductburners not tested, variable-load testing for NOx deferred).
