PFAS (Per- and Polyfluoroalkyl Substances) Resources

GMCG is committed to protecting water resources in the Ossipee Watershed. PFAS are an emerging contaminant, meaning their full impacts on human health are not yet known. While GMCG is not equipped to sample for PFAS, we will continue to stay informed with the latest PFAS information and keep the community updated on how PFAS are affecting our area.

Brandon Kernan:

NHDES sampling is focused on those areas most susceptible to contamination. They primarily target wells that are in close proximity to other wells where exceedances of drinking water standards have already been identified. NHDES will occasionally conduct more general sampling for screening purposes, but do not presently have anything to offer due to time and budget constraints.

Residents are able to request sampling at the link below. NHDES reviews this information and try to incorporate as many requests as possible into our work.

NHDES does recommend private well owners sample for PFAS but acknowledges the cost is prohibitive relative to the traditional contaminants that we recommend be tested. Labs could charge $250-$550 per sample. Many subcontract the work and mark the cost up quite a bit. The cost would be lower if you were to seek bids and deliver the bottles in batches. Analytical has a lot of couriers in the state so shipping could be cheaper with them.


Maine Department of Environmental Protection contacts for PFAS:

Chris Evans:

Amy Lachance:

Maine does not recommend private well owners sample for PFAS due to complexities. Maine does offer reimbursement for sampling of wells near lands that where sludge was spread. Watch “Ask the I-Team: Is there an at-home test to detect PFAS in Maine water?here.
