Government Sampling Record for 1,2,3-TCP in Kent County Water

EPA public water system data shows no 1,2,3-trichloropropane detected above 0.03 µg/L

The Kent County Water Authority, serving Coventry, Cranston, East Greenwich, North Kingstown, Scituate, Warwick, West Greenwich, West Warwick, and surrounding areas, reported no detections of 1,2,3-TCP above the EPA reporting level from 2013 to 2015. This federal dataset comes from the Unregulated Contaminant Monitoring Rule and documents the public water system's sample results, not individual home water tests.

How 1,2,3-Trichloropropane Originated and Entered Groundwater

Historical soil fumigation with chlorinated solvents during mid-20th century

1,2,3-TCP is a chlorinated solvent once used as a soil fumigant between the 1950s and 1980s. Over time, this chemical has penetrated deep groundwater layers due to its persistence and mobility, decades after original application ceased.

The Sensitivity of 1,2,3-TCP Reporting Levels Compared to Other Contaminants

The reporting level of 0.03 micrograms per liter (µg/L) is notably low

This reporting threshold for 1,2,3-TCP, equivalent to 0.03 parts per billion (ppb), is thousands of times lower than levels used for common metals and other contaminants, reflecting the focus on detecting even trace amounts rather than setting a health violation limit.

Potential Effects if 1,2,3-TCP Is Present Over Time

Long-term presence without treatment may affect water quality aesthetics

While no health-based violations have been recorded, untreated 1,2,3-TCP can contribute to water taste or odor changes in some circumstances. It does not indicate contamination levels that require regulatory action under current EPA standards.

Changes in Tap Water After Implementing the Pentair 1,2,3-TCP Filter

Reduction of trace levels of chlorinated solvent compounds

Using the Pentair 1,2,3-TCP Filter, water in the home shows reduced presence of 1,2,3-trichloropropane at the tap. This device ships ready to configure and uses documented filtration technology to address this specific chlorinated solvent.

Understanding Certified Laboratory Testing for 1,2,3-TCP

Laboratory reports show concentrations in micrograms per liter (µg/L) or parts per billion (ppb)

A certified test for TCP will measure trace amounts using sensitive instruments. Results below 0.03 µg/L indicate levels under the EPA reporting threshold, while any detection above this level is a documented measurement not a violation or safety finding. Homeowners should interpret lab values accordingly and consider retesting if concern persists.

How 1,2,3-TCP Enters Kent County Groundwater and Distribution Systems

Legacy pesticides and chlorinated solvents leach from historical use sites

This chlorinated solvent enters groundwater primarily through soil infiltration in areas historically used for soil fumigation or industrial chemical applications. The Kent County Water Authority’s surface water source may also be influenced by regional watershed runoff carrying trace levels of 1,2,3-trichloropropane.

Conclusion: Addressing Your 1,2,3-TCP Concern with the Pentair 1,2,3-TCP Filter

If your certified laboratory tests detect 1,2,3-trichloropropane near or above the EPA reporting level, the Pentair 1,2,3-TCP Filter offers a direct-purchase solution that ships ready to configure for home use. It reduces this chlorinated solvent in your tap water to support your household’s water quality goals.
