A laboratory test report for 1,2,3-trichloropropane (1,2,3-TCP) typically shows numerical results indicating the concentration of this chemical in micrograms per liter (µg/L). For public water systems, these results reflect a snapshot from federal occurrence monitoring rather than a compliance test or health violation.
What Changes at Your Tap After Using the C-Series 1,2,3-TCP Filter
The C-Series 1,2,3-TCP Filter is designed to reduce 1,2,3-TCP presence if confirmed in your household water. While Mesa’s public water system monitoring from 2013 to 2015 found zero detections above the reporting level of 0.03 µg/L, household water quality can differ. Using this filtration system can lower any trace amounts of 1,2,3-TCP or similar organic compounds that standard treatment might not address.
Consequences of Leaving 1,2,3-TCP Untreated Over Time
1,2,3-TCP is a synthetic chemical historically used in industrial applications and is not naturally occurring. Prolonged exposure to this compound, if present at measurable levels, could raise questions about long-term ingestion. However, Mesa’s system monitoring shows no detected levels, meaning routine exposure via this public supply is not indicated by the data. Untreated household water with unknown sources or private wells may warrant testing to understand any potential exposure.
How Sample Depth and Water Source Affect 1,2,3-TCP Expectations
Mesa’s water comes from surface water sources serving a large population through a centralized system. Surface water and groundwater typically vary in how they carry industrial chemicals. The federal monitoring results reflect system-wide averages and do not capture private wells, where depth and geology could influence 1,2,3-TCP presence differently. Sample depth in well water can be critical, but this data set focuses on the municipal supply from surface sources.
Interpreting the Median and Range in Mesa’s 1,2,3-TCP Monitoring Record
From the EPA’s UCMR3 monitoring of the City of Mesa’s system, 61 samples were analyzed, with none detecting 1,2,3-TCP above the 0.03 µg/L reporting level. The median concentration is effectively below detection, and the range shows no measurable spikes in those years. This means that the public water system’s 1,2,3-TCP levels have consistently been at or below the minimum detection threshold used in federal occurrence monitoring.
Key Details to Record When Seeking Treatment Advice
- Confirm whether your water comes from the City of Mesa public system or a private well.
- If from a private source, note sample depth, well type, and history of industrial or agricultural activity nearby.
- Have a certified laboratory water test report for 1,2,3-TCP and other chemicals handy to guide treatment solutions.
- Understand the specific concentration of 1,2,3-TCP measured, if any, to assess whether filtration is beneficial.
The federal data discussed here comes from the City of Mesa public water system and covers a broad monitoring campaign conducted between 2013 and 2015. This information is sourced from EPA records and reflects the system as a whole, not individual household water quality. For details, consult the EPA’s Unregulated Contaminant Monitoring Rule (UCMR3) public water system records.
