What Regional PFAS Data Can and Cannot Tell You

Government sampling for the CTWC Shoreline Region-Guilford System covers public water serving parts of Clinton, Guilford, Madison, Old Saybrook, Westbrook, and New Haven County. These results reflect system-wide monitoring of surface water sources, not specific household water quality. To confirm your home's water PFAS levels, specific testing on your tap or well is necessary.

Understanding the PFAS Mixture Hazard Index

Measurement Includes Multiple Fluorinated Compounds

Samples show several per- and polyfluoroalkyl substances (PFAS), often called "forever chemicals," including PFOA, PFOS, PFHxS, PFBS, PFHxA, PFPeA, and PFBA. These compounds coexist in varying amounts in tested water.

Hazard Index Indicates Combined Presence, Not Safety Status

The hazard index for mixtures is a method to account for combined exposures. It does not indicate water safety or health risk directly but helps regulatory and scientific bodies assess cumulative potential effects.

Which Fluorinated Compounds Have 2024 Federal MCLs

PFOA and PFOS Carry Federal Maximum Contaminant Levels

• PFOA: MCL set at 4.0 ng/L (nanograms per liter, parts per trillion)
• PFOS: MCL set at 4.0 ng/L

Other Detected Compounds Do Not Currently Have Federal MCLs

• PFHxS, PFNA, HFPO-DA, PFBS, PFHxA, PFPeA, PFBA, and PFHpA do not have federal MCLs (2024)

Detected Levels in Shoreline Region-Guilford System

• PFOA and PFOS were detected above reporting levels but mostly below federal MCLs
• No compounds other than PFOA and PFOS exceeded their respective federal MCLs in this system

Maintenance Rhythm for the Pentair PFAS Forever Chemicals Filter

Ships Ready to Configure for Home Use

The Pentair PFAS Forever Chemicals Filter is designed to be added to a home water treatment setup without needing professional support. It arrives ready to configure and operate.

Regular Filter Replacement Keeps Performance Effective

Replacing filter cartridges periodically according to product guidance is essential to maintain PFAS reduction. Exact timelines depend on usage and water quality but following recommended rhythms ensures continued performance.

What to Record Before Seeking Treatment Advice

Identify Your Water Source Type

Know whether your home uses municipal surface water, well water, or a different supply as regional PFAS presence varies accordingly.

Gather Your Water Test Data

Have recent PFAS testing results or schedule testing to understand your specific concentrations. Local data alone cannot confirm your home's water quality.

Note Any Local Environmental Factors

Firefighting foam use, landfills, or textile industry activities nearby can influence PFAS presence and may warrant additional considerations.

Sample Size and Data Meaning in This Region

22 Samples Spanning 2024-2025 Monitoring Period

The data includes 22 distinct samples from the system over approximately 18 months, reflecting temporal and spatial variability at the system level.

Sample Size Provides Regional Insight, Not Individual Confirmation

Sampling reflects water delivered to many households but can't substitute for testing individual household taps or private wells.

Detection Above Reporting Levels Only Indicates Presence

Detecting a compound means it was measured above a threshold, never that it violates legal limits or causes health concerns on its own.

Summary

The EPA data for the CTWC Shoreline Region-Guilford System in New Haven County documents traces of various PFAS compounds, including those with federal MCLs. This information clarifies regional water exposure conditions but does not specify any individual home's water quality. Using a Pentair PFAS Forever Chemicals Filter offers a documented method to address per- and polyfluoroalkyl substances at the household level when combined with accurate testing and informed decisions.
