Choosing Household Water Equipment for 1,2,3-TCP in Salt Lake County

Are you wondering how to address 1,2,3-TCP in your household water in Salt Lake County? This checklist breaks down key considerations for choosing between water-treatment equipment classes tailored to local conditions in the Salt Lake City Water System.

Why the Reporting Level for 1,2,3-TCP Is Extremely Low Compared to Metals

The reporting level for 1,2,3-trichloropropane is 0.03 micrograms per liter (µg/L)

This level is thousands of times lower than typical detection limits for common metals, reflecting the sensitivity needed for chlorinated solvents. It is a federally set threshold that defines the minimum concentration to be reliably detected in monitoring, not a health-based limit.

Detection above this level is a measured occurrence, not a health violation

No results for 1,2,3-TCP in the Salt Lake City Water System were detected above 0.03 µg/L during the 2013-2015 EPA monitoring. Detection means measurement, not unsafe or illegal levels.

How a Mid-20th Century Soil Fumigant Impurity Reached Deep Groundwater Decades Later

1,2,3-TCP originated as an impurity in soil fumigants used in the 1950s-1980s

This chlorinated solvent was not intentionally added but appeared as a contaminant. Over decades, it migrated from agricultural soils into deep groundwater reservoirs, which can affect surface water sources such as those supplying Salt Lake City.

Salt Lake City Water System relies on surface water, influenced by regional groundwater pathways

Regional monitoring of this system includes assessment for 1,2,3-trichloropropane to track the presence of legacy contaminants linked to historical land use.

How the Treated Water Differs at the Tap Once the Documented Technology Is in Place

Treated water aims to minimize 1,2,3-TCP regardless of initial detected levels

Water treatment with targeted technology reduces the chlorinated solvent's concentration, improving aesthetic qualities and providing peace of mind without implying previous water safety issues established by government data.

Household water equipment designed for 1,2,3-trichloropropane addresses this constituent specifically

Such equipment operates to neutralize or remove TCP, serving households that seek additional protection beyond municipal treatment.

How Documented Treatment Technology Removes or Neutralizes 1,2,3-Trichloropropane

The Autotrol 1,2,3-TCP Filter uses an engineered process compatible with residential demand

This system applies specialized filtration principles to target and reduce the chlorinated solvent in household water. It ships ready to configure for direct purchase and use.

The technology’s function is to adsorb or chemically alter the 1,2,3-TCP molecules

Through this mechanism, the treated water at the tap delivers a reduction in 1,2,3-trichloropropane concentration without relying on broad municipal interventions.

What a Certified Laboratory Test Reports for 1,2,3-TCP and How to Read It

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

Results below 0.03 µg/L indicate non-detection for 1,2,3-TCP according to EPA monitoring levels. Any number above is a detection, not an exceedance of a health standard.

Interpreting results requires understanding the difference between detection level and safety limits

Since there is no federal maximum contaminant level (MCL) for 1,2,3-TCP, detection simply documents presence and concentration. Safety determinations require health-based guidelines beyond occurrence data.

The Salt Lake City Water System, serving over 380,000 people, had 33 samples analyzed from 2013 to 2015 with no detection of 1,2,3-TCP above 0.03 µg/L according to EPA records. This information, sourced from the EPA's Unregulated Contaminant Monitoring Rule database, describes system-wide monitoring results, not individual household water quality. For your own water, a certified laboratory test is necessary to determine 1,2,3-trichloropropane levels precisely.
