Understanding PFAS Regulations in Connecticut
Connecticut has proactively addressed per- and polyfluoroalkyl substances (PFAS) contamination, recognizing the potential health risks associated with these persistent chemicals. While there are currently no enforceable federal or state Maximum Contaminant Levels (MCLs) for PFAS in drinking water, the Connecticut Department of Public Health (CT DPH) has established an advisory limit of 70 parts per trillion (ppt) for the sum of six PFAS compounds.

Public water systems (PWSs) in Connecticut have conducted multiple rounds of testing since 2013, with most sources showing no detectable levels of PFAS. Source: CT.gov However, the state continues to monitor and assess potential contamination sources to ensure the safety of its drinking water.
Recent Legislative and Regulatory Updates
In 2019, Connecticut established an Interagency PFAS Task Force, which developed a comprehensive PFAS Action Plan. Key recommendations included testing drinking water for PFAS and setting advisory limits. Source: bethel-ct.gov
Furthermore, starting October 1, 2024, Connecticut will prohibit the use or sale of PFAS-containing biosolids or wastewater sludge, aiming to prevent environmental contamination from these sources.
Here are additional Connecticut PFAS Regulatory compliance deadlines and milestones:
- April 1, 2029: Connecticut expected to align with federal MCLs for PFAS compounds
- October 1, 2024: Prohibition on use or sale of PFAS-containing biosolids or wastewater sludge takes effect
- March 1, 2024: Implementation of public notification requirements for detected PFAS in water systems
- June 5, 2023: Legislation was passed prohibiting PFAS-containing biosolids or wastewater sludge
- January 1, 2023: Connecticut initiated expanded monitoring of PFAS in groundwater near potential contamination sources
- March 15, 2021: Public water systems began conducting mandatory PFAS testing
- January 1, 2020: CT DPH established an advisory limit of 70 parts per trillion (ppt) for the sum of six PFAS compounds
- November 1, 2019: The Task Force developed a comprehensive PFAS Action Plan
- July 8, 2019: Connecticut established an Interagency PFAS Task Force

Frequently Asked Questions
What are the health risks associated with PFAS exposure?
PFAS exposure has been linked to various health concerns, including developmental issues, liver damage, immune system effects, and increased risk of certain cancers. Due to their persistence, PFAS can accumulate in the human body over time, leading to potential long-term health effects.
How can residents ensure their drinking water is safe?
Residents can review water quality reports provided by their local water utilities, which include PFAS testing results. For private well owners, it’s advisable to conduct regular water testing and consider treatment options like activated carbon filters if PFAS are detected.
Connecticut’s Unique Approach to PFAS Management
Connecticut’s proactive stance includes not only setting advisory limits but also implementing bans on PFAS-containing products. The state’s comprehensive approach addresses PFAS contamination at multiple levels, aiming to mitigate exposure risks and safeguard environmental and public health.
