Understanding Data and Limits for 1,2,3-TCP in Your Area

Area-wide sampling does not reflect individual household water quality

The available government data describes water quality from the Meriden Water Division, covering Berlin, Cheshire, Meriden, Southington, Wallingford, and nearby parts of New Haven County. This means readings for 1,2,3-trichloropropane (TCP) represent the source water treated for the public system, not the specific water from your residential tap or well.

Data shows no 1,2,3-TCP detection above 0.03 micrograms per liter (µg/L)

Between 2013 and 2015, 24 samples for 1,2,3-TCP in this public water system showed no measurements exceeding the reporting level of 0.03 µg/L (0.03 parts per billion). This reflects the detection limits of the federal monitoring but is not a safety or violation threshold, as no federal maximum contaminant level (MCL) exists for TCP.

Checklist for Assessing Technical Factors Affecting Treatment Choice

1,2,3-Trichloropropane's resistance to air stripping influences equipment selection

TCP is a chlorinated solvent that does not readily volatilize, making air stripping ineffective as a treatment approach. This chemical property means homeowners considering treatment equipment should focus on filtration or adsorption technologies specifically capable of addressing TCP.

Reporting levels for TCP are far lower than typical metal contaminant limits

The detection threshold of 0.03 µg/L for TCP is orders of magnitude lower than reporting levels for common metals in water monitoring. This low measurement level reflects TCP’s potential persistence and the desire to closely track it, despite no established federal MCL.

Seasonal and multi-year variation is documented from early 2013 through late 2014

The federal monitoring record spans samples from January 2013 to December 2014. Consistent non-detection of TCP during this period indicates stable water quality concerning this solvent at the public system level, though year-to-year changes can occur and warrant periodic testing.

Match treatment capacity to your daily household water use

When choosing equipment to address TCP, consider your residence's water demand to ensure adequate capacity. Product specifications for Pentair 1,2,3-TCP Filter outline flow rates and capacity aligned with typical household consumption, offering a reliable method to configure treatment without waste or undersizing.

Additional Considerations for Water Quality Management

Aesthetic secondary standards differ from health-based limits for TCP

While federal law has no maximum contaminant level for TCP, secondary standards exist for related water quality parameters affecting taste, color, and staining potential. These are separate from health-based indicators and should not be confused when evaluating water quality concerns.

Plumbing materials and age impact water quality separately from source water

Even with stable water from the public system, household plumbing—including pipe material and age—can influence the presence or concentration of certain substances. Testing your home's water specifically is the only way to determine its individual profile regarding 1,2,3-TCP or other constituents.

Summary and Next Steps

The documented water-quality record for the Meriden Water Division, serving multiple New Haven County communities, shows no 1,2,3-trichloropropane detected above the 0.03 µg/L reporting level during federal monitoring from 2013 to 2015. This data pertains to system-wide source water and is not an individual household assessment.

For households seeking additional protection against 1,2,3-TCP or similar chlorinated solvents, technology such as the Pentair 1,2,3-TCP Filter, which ships ready to configure for residential demand, offers a targeted solution. To understand your home's specific water quality, direct testing for 1,2,3-trichloropropane and related compounds is necessary.
