Opening: What does it mean if I find 1,2,3-TCP in my water in De Soto Parish?

If your household water comes from the Keatchie Water System in De Soto Parish, EPA monitoring from 2013-2015 found no 1,2,3-trichloropropane above the reporting level of 0.03 micrograms per liter (µg/L, also parts per billion). This means no federal standard was exceeded in that area’s public groundwater supply, but individual water quality can only be confirmed by specific testing of your own source.

1. Granular activated carbon contact time: why bed depth matters more for TCP than for taste

1,2,3-TCP is a chlorinated solvent that resists removal by simple filtration or taste-based treatment methods. Effective filtration relies on granular activated carbon (GAC), where depth of the carbon bed influences contact time and adsorption efficiency. Longer contact time from a deeper bed enhances the carbon’s ability to adsorb TCP molecules, which are more challenging to capture than substances affecting taste or odor.

2. How the treated water differs at the tap once the documented technology is in place

After water passes through the Fleck 1,2,3-TCP Filter, which uses a specialized carbon filtration system, tap water is expected to have reduced levels of chlorinated solvents like TCP, resulting in improved water quality with respect to this constituent. This treatment does not typically affect other water characteristics such as minerals or pH, focusing specifically on compounds like 1,2,3-trichloropropane.

3. Why 1,2,3-trichloropropane resists air stripping and what that means for treatment choice

Unlike some volatile contaminants, 1,2,3-TCP does not readily volatilize, meaning air stripping is generally ineffective. This chemical property directs treatment toward adsorption technologies rather than aeration methods, guiding households to solutions designed specifically for chlorinated solvents such as the Fleck technology highlighted here.

4. What changes for a large household, a second home, or a seasonal property

Household size and usage patterns influence the capacity and frequency of filter replacement needed. Larger families or properties with intermittent use require consideration of higher flow rates and potential periods of inactivity, which can impact the performance and maintenance cycle of the filtration technology designed to address TCP.

5. The role of plumbing material and age, separate from the source water

Plumbing materials within a home and their condition do not affect the presence of 1,2,3-trichloropropane, which originates from the groundwater source. However, older plumbing materials might interact differently with treated water and influence taste or aesthetic qualities, though this is separate from TCP concerns.

6. How a soil fumigant impurity from the 1950s-1980s reached deep groundwater decades later

1,2,3-trichloropropane was historically an impurity in certain soil fumigants used in agriculture during the mid-20th century. This chlorinated solvent has migrated slowly through soil layers to reach deep groundwater sources supplying systems like Keatchie Water System. The EPA’s detection record reflects this long-term environmental legacy rather than recent contamination events.

Closing

The EPA’s public water system record for Keatchie Water System in De Soto Parish covers measurements of 1,2,3-TCP from 2013 to 2015, showing no detections above the reporting level of 0.03 µg/L (parts per billion). Individual households seeking to know their specific water quality should perform testing on their own tap water. For targeted reduction of 1,2,3-trichloropropane, the Fleck 1,2,3-TCP Filter ships ready to configure and uses granular activated carbon technology suited to removing this persistent chlorinated solvent.
