PFAS Vulnerability Assessment Forms were completed to identify risk activities and their degree of risk. Municipal land use activities of high-risk potential and moderate-risk potential were identified on a GIS base map. Locations such as fire departments, a wastewater treatment plant, airports, and landfills were identified. Non-municipal properties’ activities were reviewed for PFAS sources using the Water Division’s watershed inspection logs, EPA’s database, assessors mapping, and aerial imagery. A drive-by was also conducted to confirm exterior site activities.
The results of the investigation were compiled into an amendment for the City’s Water Supply Plan.
PFAS above certain levels may pose risks to human health.
Potential PFAS source investigations are important to identify in order to protect water resources. Protections can be implemented by managing PFAS sources and treating water for PFAS level reductions.
