Horsley Witten Group has provided on-call Licensed Site Professional (LSP) services for the airport since 1998. These services have included environmental assessment, subsurface investigation, remediation, and risk assessment to address localized soil, groundwater, surface water, and sediment contamination.
HW is currently investigating the extent of per and polyfluoroalkyl substances (PFAS) in soil, groundwater, and/or surface water at the airport. The Phase II Comprehensive Site Assessment and Phase IV Remedy Implementation Plan have been completed, which utilized environmental forensics to document multiple comingled PFAS plumes relating to both airport and non-airport related PFAS sources. HW installed two caps to prevent further migration of PFAS to groundwater, and has conducted public outreach including facilitating public meetings, and engaging the public for comments on various regulatory reports.
