Petroleum contamination assessment, risk evaluation, monitoring and reporting
AKT Peerless has been working on this leaking underground storage tank (LUST) project since the release was originally discovered on December 26, 2019 until the present. AKT Peerless conducted the following remedial investigation activities in a primarily residential/ agricultural area adjacent to The North Country Store: (1) Determine the nature and extent (both horizontal and vertical) of an unleaded gasoline release in soil and groundwater using soil borings and permanent monitoring wells, (2) Determine the nature and extent of soil gas contamination using interior and exterior soil gas sampling points at the Site property, (3) Determine the extent of residual light non-aqueous phase liquid (LNAPL) in the soil and groundwater, (4) Sampled an on-site and a nearby residential drinking water well to confirm that the release had not impacted these potential receptors, (5) Requested/obtained site-specific target levels (SSTLs) from EGLE, (6) Following the preparation and submittal of the Initial Assessment Report (IAR) and Final Assessment Report (FAR) instituted quarterly groundwater and soil gas monitoring, (7) Conducted soil gas and ongoing groundwater monitoring in the affected areas and outside the plume to confirm delineation, and (8) Reporting monitoring results to EGLE and off-site property owners.
AKT Peerless conducted remedial investigation activities to define the horizontal and vertical extent of the soil and groundwater contamination related to the leaking underground storage tanks.
AKT Peerless also conducted soil gas and groundwater natural attenuation monitoring to demonstrate plume stability, reported monitoring results to the Michigan Department of Environment, Great Lakes and Energy (EGLE) and prepared/submitted reports as required under Leaking Underground Storage Tanks, of the Natural Resources and Environmental Protection Act, 1994 of PA 451, as amended (NREPA).
