When evaluating water quality concerns for your household in Berlin, Cheshire, Meriden, Southington, Wallingford, or nearby areas in New Haven County, it is important to recognize what public water system data does and does not say about your specific water. Data from the Meriden Water Division covers a large service area and many connections, but individual household water quality should be confirmed by a personal well or tap water test, especially if existing equipment has ceased to perform as expected.
How a soil fumigant impurity from the 1950s-1980s reached deep groundwater decades later
TCP is a legacy chlorinated solvent once used as a soil fumigant
Persistence in groundwater is due to slow natural degradation over decades
Its movement into surface water sources reflects historical agricultural practices in the region
How California's 5 ng/L state limit compares with the absence of a federal MCL
California’s 5 nanograms per liter (ng/L) limit translates to 0.005 micrograms per liter (µg/L)
The EPA sets no federal maximum contaminant level (MCL) for 1,2,3-trichloropropane
Sampling detects concentrations but does not determine health-based violations under federal rules
What questions a commercial or industrial operator adds that a household does not
Operators must evaluate TCP levels for regulatory compliance and process impact
Households focus on water quality for health, taste, and equipment longevity
Commercial testing often involves more frequent and expansive sampling
How seasonal or multi-year variation shows in the record (dates and ranges given)
Monitoring from January 2013 to December 2014 shows no detection above 0.03 µg/L reporting level
Data reflects surface water source quality supplying tens of thousands of residents
Variations in TCP readings over time are minimal within the public water system data
What 'detected', 'median' and 'range' mean in the sampling record on this page
'Detected' means the chemical was measured above laboratory reporting limits, not a violation
Median represents the middle value of detected readings when results exist
Range reflects the span from the lowest to highest detected concentration recorded
Why 1,2,3-trichloropropane resists air stripping and what that means for treatment choice
TCP has low volatility, making air stripping ineffective for reduction
Targeted filtration technologies are required to address TCP presence at residential points
Certain carbon-based filtration systems are demonstrated to effectively reduce TCP
For households in New Haven County where existing equipment has failed to address 1,2,3-trichloropropane concerns, the C-Series 1,2,3-TCP Filter ships ready to configure. This product is designed to meet the specific challenge of removing this chlorinated solvent, providing an approach aligned with the demand your own water tests indicate.
