Household Symptoms Related to 1,2,3-TCP
1. Absence of Specific Taste or Odor
1,2,3-trichloropropane (1,2,3-TCP) does not produce identifiable taste or smell in water. If you notice odd tastes or odors, other causes should be considered.
2. No Visible Water Appearance Changes
This constituent is colorless and does not alter water clarity or color.
3. Symptoms Not Exclusive to 1,2,3-TCP
Water issues like staining or cloudiness point to other compounds, not 1,2,3-TCP.
Reading the Public Water System Record Example
1. Median and Range from Security WSD
For the Security Water System serving El Paso County, 38 monitoring results showed no detections of 1,2,3-TCP above the reporting level (0.03 micrograms per liter).
2. Implication for Homeowners
This means the system’s sampled water typically has 1,2,3-TCP levels below instrument detection limits, though individual home water can differ and requires direct testing.
Interpreting a Certified Laboratory Test for 1,2,3-TCP
1. Reporting Levels and Units
Certified labs report 1,2,3-TCP concentration in micrograms per liter (µg/L or ppb). Results below 0.03 µg/L are reported as nondetect.
2. What a Detection Means
A detection is a measurement, not a violation or safety determination. Confirm your specific household water by testing.
3. Using Results to Choose Treatment
Testing informs the need and scale for appropriate treatment equipment for your household demand.
How Water Source and Sample Depth Affect Expectations
1. Surface Water Source in El Paso County
Security WSD relies on surface water; 1,2,3-TCP tends not to accumulate in these sources at detectable levels per EPA records.
2. Variability by Sample Point
Results can vary with sample depth and local plumbing. Testing your tap water directly is necessary for household decisions.
Long-Term Effects of Untreated 1,2,3-TCP Presence
1. Lack of Immediate Sensory Indicators
Because 1,2,3-TCP has no color, smell, or taste, long-term presence can go unnoticed without testing.
2. Importance of Consistent Monitoring
While no violations have been recorded, ongoing testing is advisable to confirm water quality over time.
What Not to Conclude from Area Data
1. Area Measurements Are Not Individual Home Tests
EPA data reflect system averages and monitoring points, not singular household water conditions.
2. No Safety Violations Found in System Records
Security WSD has zero health-based violations for 1,2,3-TCP, indicating regulatory standards are currently met.
3. Detection Absence Does Not Guarantee Zero Presence
Only direct testing of your home water can confirm your specific levels.
For households evaluating treatment options amid concerns about 1,2,3-TCP, the Autotrol 1,2,3-TCP Filter ships ready to configure and provides a documented means to reduce this constituent effectively. Selecting treatment tailored to your household demand is an important step after verifying your water’s composition through certified lab analysis.
