1,2,3-Trichloropropane (1,2,3-TCP) is a concerning contaminant often found in water supplies affected by past fumigant use. Classified as a probable carcinogen, this chemical poses serious health risks even at extremely low concentrations. Because of its persistence and strict regulatory limits, removing 1,2,3-TCP from your water requires a specialized filtration approach designed to meet these tough standards.

The system that solves it

Our 1,2,3-TCP reduction system is built around a robust, heavy-duty Big Blue whole-house cartridge housing that stands up to demanding water conditions. This system accommodates targeted cartridge media specifically formulated to capture and reduce 1,2,3-TCP, ensuring the filtration media is precisely matched to the contaminant. The design is straightforward and reliable: it operates without the need for electricity or a drain, eliminating complexity and minimizing maintenance requirements. Changing the cartridge is quick and easy, accomplished in minutes using a simple spanner wrench. Additionally, the system supports stackable stages, allowing for flexible configurations tailored to your water treatment needs.

• Heavy-duty Big Blue cartridge housing for whole-house protection
• Cartridge media engineered for 1,2,3-TCP reduction
• No electricity or drain required for operation
• Fast cartridge changes with included spanner wrench
• Stackable stages enable customizable treatment setups

What it does for your home

• Effectively reduces 1,2,3-TCP levels to meet stringent safety standards
• Protects your household from exposure to a probable carcinogen
• Treats water at the whole-house level or as a point-of-use solution
• Employs deep-bed carbon contact for thorough contaminant capture
• Delivers peace of mind for homes with wells impacted by past fumigants
• Simple maintenance supports ongoing reliable performance

This filtration system not only safeguards your family’s health by addressing a challenging contaminant but also integrates seamlessly into your home’s water treatment setup. Whether installed at the point of entry or for specific faucets, it ensures clean, safer water throughout your property.

Why it works

The key to removing 1,2,3-TCP lies in the media inside the cartridge: a deep bed of coconut-shell activated carbon. This type of carbon provides a large surface area and is particularly effective at adsorbing trace organic contaminants like 1,2,3-TCP. The critical factor is contact time—1,2,3-TCP requires extended exposure to the carbon to be reliably captured. The deep-bed design ensures water flows through enough carbon material, maximizing the time the contaminant is in contact with the media. As a result, the system achieves consistent, effective reduction of this difficult compound, far beyond what standard carbon filters can deliver.

Sizing it right

Correctly sizing your 1,2,3-TCP reduction system depends on your household water usage, flow rate, and concentration of the contaminant in your source water. Whole-house systems typically need cartridges rated for the total volume your home uses daily, while point-of-use systems require a capacity aligned with faucet flow rates. Selecting the right configuration ensures efficient removal without unnecessary replacement frequency. We offer free, expert sizing assistance to help you determine the optimal system based on your well water test results and household demands.
