EPA released revised Health Advisories on four PFAS compounds based on information on lifetime exposure. These advisories are non-enforceable and non-regulatory.
Connecticut Department of Public Health (DPH) also released updated guidance with Action Levels for four individual compounds. These new Action Levels replace the previous Action Level of 70 parts per trillion (ppt).
New Action Levels
Groton Utilities no longer conducts well water testing.
February 2022 Update
As part of the Safe Drinking Water Act, the EPA coordinates the Unregulated Contaminant Monitoring Rule (UCMR) program. Every five years drinking water companies are required to collect samples of the drinking water that are analyzed for priority unregulated contaminants.
Analysis of these samples provides the EPA with scientifically-valid data on these contaminants that are currently unregulated in drinking water. The data improves the EPA's understanding of the frequency at which they are found and at what levels and helps ensure science-based decision-making.
Samples will be collected from 2023 to 2025.
Once we have collected samples for UCMR 5, GU will share that data in our Water Quality Report and on GU's website detailing Perfluorinated Chemical testing.
