Chloramine in Key West’s Public Water Supply
The public water system serving Key West, Monroe County, FL, is managed by the Florida Keys Aqueduct Authority (FKAA) through the Florida Keys R.O. Plants system, which relies on groundwater as its source. This system supplies water to approximately 30,000 residents across the region.
Government sampling data from the EPA’s Safe Drinking Water Information System (SDWIS) public water system record (FL5444047) confirms the ongoing use of water treatment involving process code 640, which corresponds to chloramine disinfection. Chloramine is a combination of chlorine and ammonia used to maintain disinfectant residuals in the distribution system and control microbial growth.
What Chloramine Means for Residential Water Users
Chloramine contributes to water safety by helping prevent bacterial contamination. However, it can also cause certain aesthetic and practical issues for households. These may include altered taste and odor, potential staining, and challenges for some fish tanks or sensitive users who rely on chloramine-free water.
Importantly, the EPA record for FKAA’s water system shows one health-based violation on file, but there is no specification that this violation relates directly to chloramine levels. Public system data does not provide individual household water concentrations or conditions, so the presence of chloramine detected by the authority does not imply any specific circumstance in any single home.
Testing Your Household Water Quality
To understand the quality of your water regarding chloramine or other treatment residuals, professional testing of your household water is necessary. Testing can determine chloramine concentration, chemical composition, and other parameters that influence water quality and suitability for your household use.
Such information helps identify whether chloramine causes specific concerns like taste, odor, or equipment wear.
Mitigating Chloramine Effects with Carbon Filtration
One well-documented technology for reducing chloramine in household water is catalytic carbon filtration. The Fleck City Whole-Home Protection System employs this method, featuring a 32,000-grain capacity carbon filter designed to treat the water delivered to the entire household.
This system ships ready to configure, enabling homeowners to incorporate carbon filtration that reduces chloramine concentration, improving water aesthetics and usability. While it does not change the source or municipal treatment, it addresses water quality on the point where it enters the residential plumbing system.
Carbon filtration works by adsorbing chloramine molecules, which improves taste and odor and can protect plumbing fixtures and appliances sensitive to chloramine’s chemical effects.
Summary
- The FKAA system serving Key West uses chloramine as a disinfectant, based on EPA records.
- Chloramine supports water safety but can affect water taste, odor, and suitability for sensitive uses.
- EPA data shows one health-based violation for FKAA, unrelated to chloramine specifically.
- Individual water quality, including chloramine levels, requires direct testing of household water.
- The Fleck City Whole-Home Protection System offers carbon filtration designed to reduce chloramine, configured for whole-house treatment.
