Right now, you need to decide if your household’s current water treatment can keep up with the 1,2,3-trichloropropane (1,2,3-TCP) situation in Silver Bow County’s water supply, or if additional filtration is necessary.

If you notice no new taste, smell, or staining problems but your existing equipment seems less effective

1,2,3-TCP is a chemical compound that can be detected in surface water sources. This constituent does not produce odors or visible changes, so it often goes unnoticed without testing. If your current treatment equipment no longer meets your household’s water quality expectations or throughput, it could be time to consider a dedicated filter designed to address 1,2,3-TCP.

Note that the Butte Silverbow Water Department's public system records from 2013-2015 found no detections of 1,2,3-TCP above the established reporting level, indicating the source water measured very low or no presence at those times. This record covers over 12,900 service connections throughout Butte and Silver Bow County and is based on surface water supply.

If you have a certified lab test for your home's water showing 1,2,3-TCP data

A certified laboratory test report will specify 1,2,3-TCP concentrations in micrograms per liter (µg/L). Because the public system record shows no detections above 0.03 µg/L during the survey period, values near or below this level are consistent with the broader water supply. The absence of federal maximum contaminant levels (MCLs) for 1,2,3-TCP means such numbers are for information and monitoring, not regulatory limits.

Interpreting a lab report involves checking if the 1,2,3-TCP concentration is above the lab’s reporting level and comparing it to your system’s past measurements. If results indicate the chemical is present in amounts that existing equipment cannot handle, additional filtration solutions may help improve water quality.

If your household is large, a second home, or used seasonally

Water treatment capacity needs increase with household size, additional residences, or seasonal usage patterns. Equipment that worked well for a single-family home with moderate demand might struggle to maintain performance for multiple occupants or intermittent usage. This can affect flow rates, filter lifespan, and overall effectiveness against 1,2,3-TCP.

Considering these factors helps in selecting equipment capable of meeting your household’s real-world consumption and water quality management needs without overburdening components.

If you are trying to distinguish 1,2,3-TCP issues from other water quality concerns like taste or staining

Unlike minerals or secondary compounds that cause taste, discoloration, or stains, 1,2,3-TCP is a synthetic organic chemical not typically linked to such aesthetic effects. Presence or absence cannot be judged visually or by odor. This difference makes laboratory testing and targeted filtration the key approaches to managing 1,2,3-TCP.

If you want to understand terms like 'detected', 'median', and 'range' in the regional sampling record

In the Butte Silverbow Water Department’s public water system record, 'detected' means the lab instrument measured the substance above its method reporting level, not that any limit was exceeded or water is unsafe. The median and range describe the middle and spread of measured values across samples during the survey period, helping to characterize typical conditions and variability.

This data is about the public water system as a whole, not a specific household, and serves as a baseline context, not a definitive statement about any individual tap.

In sum, the Butte Silverbow Water Department serves a population of about 33,000 people via over 12,900 connections using surface water sources. Its 2013-2015 monitoring for 1,2,3-TCP found no detections above the reporting level. For more detailed information, you can consult the EPA’s official public water system records.

If you conclude that your household’s water treatment is no longer keeping pace, the Pentair 1,2,3-TCP Filter ships ready to configure and can support removal of this constituent at the point of use, complementing your existing equipment to maintain the water quality your household expects.
