The public water system Edmond PWA - Arcadia in Oklahoma County, serving nearly 80,000 people, shows no detectable levels of 1,2,3-trichloropropane (1,2,3-TCP) in federal monitoring data from 2013 to 2015, according to EPA’s UCMR3 survey.
Agricultural Land-Use History and Its Relation to 1,2,3-TCP Detections
Historical use of soil fumigants containing 1,2,3-TCP has been documented regionally as a source of groundwater contamination.
Current surface water sources for Edmond PWA - Arcadia reduce direct impact from historic agricultural leaching compared to groundwater systems.
Regional agricultural activity patterns influence where 1,2,3-trichloropropane is more likely to be detected in nearby water sources.
Changes in Household Water Use Affecting 1,2,3-TCP Treatment Needs
Larger households consume more water, increasing the volume needing treatment if 1,2,3-TCP were present.
Seasonal or second homes may experience variable water use, affecting the timing and demand on filtration equipment for 1,2,3-TCP.
Low daily water use requires consideration of equipment sizing and flow requirements to maintain effective contact time with filter media.
Interpreting Median and Range Data for Homeowners
The Edmond PWA - Arcadia record shows 44 instances tested with zero detections above 0.03 micrograms per liter (µg/L) or 0.03 parts per billion (ppb) for TCP.
Median values reflect non-detect levels, indicating the chlorinated solvent was not measurable at the federal reporting threshold during sampling.
Sampling range confirms consistent absence rather than isolated incident detection, helpful for household water quality context.
Differences Between Public System Records and Private Well Testing
Public water records represent averaged or aggregate data for entire distribution systems, not singular household water quality.
Private wells require individual testing to determine actual 1,2,3-TCP concentration, as public records do not cover private sources.
Public system compliance with health-based standards may not reflect localized variation encountered in private groundwater wells.
Comparing California’s 5 ng/L State Limit With No Federal MCL for 1,2,3-TCP
California enforces a state limit of 5 nanograms per liter (5 ng/L or 0.005 µg/L) for 1,2,3-trichloropropane, stricter than any federal standard.
No federal maximum contaminant level (MCL) exists for 1,2,3-TCP, making federal data a detection benchmark but not regulatory compliance.
Households seeking to meet California’s limit must consider filtration technologies proven to reduce chlorinated solvents below this level.
Distinguishing 1,2,3-TCP From Frequently Confused Water Constituents
1,2,3-TCP is a chlorinated solvent distinct from other volatile organic compounds and pesticides commonly monitored in water.
It differs chemically and in treatment requirements from substances causing taste or odor issues or aesthetic concerns such as chloride or total dissolved solids.
Proper identification through testing is essential before selecting targeted filtration like that provided by the Pentair 1,2,3-TCP Filter.
In summary, the Edmond PWA - Arcadia public water system’s EPA record from 2013 to 2015 shows no detectable 1,2,3-TCP above the reporting level of 0.03 µg/L (0.03 ppb). This data covers all 32,937 connections in the system, serving Oklahoma County residents. For individual households, particularly those on private wells, testing is necessary to establish specific water quality. The Pentair 1,2,3-TCP Filter ships ready to configure and can address chlorinated solvent concerns where indicated. More information is available through the EPA’s public water system database.
