Government Sampling Records for Moore County Public Utilities - Pinehurst

According to the EPA's Safe Drinking Water Information System (SDWIS) data, the Moore County Public Utilities system serving Pinehurst, North Carolina, which sources water from surface supplies, conducted monitoring for 1,2,3-trichloropropane (TCP) from February to November 2013. During 41 samples, none detected TCP above the reporting level of 0.03 micrograms per liter (µg/L or parts per billion). This data reflects conditions across the public water system, not any particular residence.

How California's 5 ng/L Standard Differs from Federal Regulations on 1,2,3-TCP

While there is no federal maximum contaminant level (MCL) established for 1,2,3-trichloropropane, California has set a state notification level at 5 nanograms per liter (ng/L), equal to 0.005 micrograms per liter. This lower threshold is used for early awareness and consumer information rather than enforcement. The absence of a federal MCL means public water systems like Pinehurst are not subject to a national regulatory limit for TCP. The EPA records no health-based violations for this system related to 1,2,3-TCP.

Persistence of 1,2,3-Trichloropropane as a Legacy Soil Fumigant Impurity

1,2,3-TCP was historically present as an impurity in soil fumigants widely used from the 1950s through the 1980s. Over decades, this chlorinated solvent has slowly migrated downward, reaching deep groundwater aquifers. Its persistence and mobility account for its occasional detection in regionally monitored water supplies, including surface-supplied systems in Moore County.

Understanding Terms: 'Detected,' 'Median,' and 'Range' in Monitoring Data

In the EPA's unregulated contaminant monitoring reports, 'detected' indicates a chemical measured above the reporting level — here, 0.03 µg/L for TCP. The 'median' refers to the middle value among all samples, describing central tendency. 'Range' presents the spread from lowest to highest concentrations found. For Pinehurst, TCP was not detected above the reporting level in any sample, so statistics like median or range for detected levels do not apply.

Influence of Sample Depth, Well Depth, and Water Source on 1,2,3-TCP Presence

Variations in 1,2,3-trichloropropane concentration depend on factors such as the depth of water wells and whether water is drawn from surface or groundwater sources. Pinehurst's system uses surface water, which typically differs in contaminant profiles compared to deep wells. These differences mean household water quality for TCP can vary and should be confirmed by testing specific to the home water source.

Role of Plumbing Materials and Age in 1,2,3-TCP Measurement

Materials and age of household plumbing influence water quality aspects such as taste and color but have limited impact on 1,2,3-TCP concentrations. This chlorinated solvent is more likely to originate from source water contamination than from plumbing. Nonetheless, aged or corroded pipes can complicate testing accuracy or leach other substances that interact with treatment methods.

Interpreting Certified Laboratory Test Results for 1,2,3-Trichloropropane

When homeowners seek to understand 1,2,3-TCP levels, a certified laboratory test reports concentrations in micrograms per liter (µg/L). Results below the quantification limit indicate non-detection at the lab's sensitivity. Reading these reports requires noting the detection limit, distinguishing between non-detects and trace amounts, and comparing findings to relevant benchmarks—recognizing that no federal MCL exists for TCP.

For households in Pinehurst needing to manage 1,2,3-trichloropropane levels exceeding their treatment capacity, the Autotrol 1,2,3-TCP Filter ships ready to configure for point-of-entry water treatment tailored to this chlorinated solvent's removal demand.
