This week, you need to decide how to respond after your home’s current water treatment has stopped working for 1,2,3-trichloropropane (1,2,3-TCP) concerns.

Understanding Measurement Terms in 1,2,3-TCP Water Sampling Records

Detected vs. Not Detected

In the Truckee Meadows Water Authority system, which serves Reno, Sparks, and Washoe County, no 1,2,3-TCP was detected above the 0.03 µg/L reporting level during 2013 to 2015 federal monitoring. 'Detected' means the chemical was measurable; 'not detected' means levels were below that threshold.

Median and Range

Since all 41 samples showed no detection above the reporting level, the median and range values effectively report no measurable presence according to this dataset.

Distinguishing 1,2,3-TCP from Other Water Concerns

1,2,3-TCP Is a Specific Organic Compound

This contaminant differs from common water issues like hardness or chlorine taste. It is typically addressed by specialized filtration rather than general conditioning methods.

Regulatory Status Does Not Imply Unsafe Water

There is currently no federal maximum contaminant level (MCL) for 1,2,3-TCP in the public system record, and no violations were found in the Truckee Meadows system. This means the water is not classified as unsafe under current federal standards.

Additional Household vs. Commercial Questions

Household Focus Is on Daily Consumption and Appliance Longevity

Residential users prioritize water quality for drinking, cooking, and appliances. Commercial operators also consider volumes, process requirements, and regulatory compliance beyond household needs.

Testing Specific Wells May Be Necessary at the Household Level

Each home’s water quality can differ, so direct testing of your own water source is the only way to confirm 1,2,3-TCP levels specifically at your location.

Sample Size and Data Confidence

Samples from 41 Testing Events Across the System

The Truckee Meadows Water Authority conducted 41 samples over the monitoring period, representing a broad system overview rather than any individual property’s water.

Small Sample Numbers May Miss Rare Variations

While no detections were found, sporadic or localized changes at individual homes cannot be ruled out without private testing.

Potential Effects of Untreated 1,2,3-TCP Presence

Extended Exposure May Affect Water Taste and Appliance Condition

Though the system record shows no exceedance, if 1,2,3-TCP were present and untreated, it might impact the taste of water and possibly lead to wear on sensitive appliances over many years.

No Immediate Health-Based Violations Recorded

Federal records confirm zero health-based violations for the public water system serving your area during the monitored timeframe.

Maintenance Requirements of the Documented Filtration Technology

C-Series 1,2,3-TCP Filter Requires Periodic Filter Replacement

This filtration technology ships ready to configure and needs regular filter changes to maintain effectiveness against 1,2,3-TCP and related compounds.

Simple Care to Sustain Protection

Routine filter maintenance helps preserve water quality benefits without complicated procedures.

The government sampling data presented here reflect the public water system of Truckee Meadows Water Authority serving 442,000 people in Reno, Sparks, and Washoe County, NV. This summary is based on EPA's unregulated contaminant monitoring rule results accessible via the EPA website.
