Bacterial Findings in the FKAA Public Water System Serving Key West
The Florida Keys Aqueduct Authority (FKAA) operates the FLORIDA KEYS R.O. PLANTS public water system, serving about 30,000 people in Key West through a single system connection. This water system relies on groundwater as its source and has a recorded EPA health-based violation related to bacterial contamination, among a total of four recorded violations. This indicates that bacterial presence has been documented by government monitoring in the area’s public water supply system.
It is important to note that this record reflects the water system’s conditions, not the water at any specific household. Individual well or home plumbing systems can differ substantially and require specific water testing to determine actual bacterial levels. Homeowners in Key West should consider obtaining comprehensive bacteriological testing for their own water to accurately evaluate their household’s water quality status.
Why Bacterial Control Matters for a Household
Bacterial presence in water can potentially affect water safety and quality. While public water systems like FKAA employ treatment processes to manage microbial contaminants, the detection of bacterial violations suggests that risk factors exist. For private households, untreated bacterial contamination can cause unpleasant tastes, odors, system biofilms, or health concerns depending on the microorganism involved.
Controlling bacteria effectively requires a reliable treatment approach that functions continuously, especially where groundwater sources and distribution conditions may allow bacterial regrowth or infiltration. For Key West homeowners, ensuring whole-home bacterial control helps protect plumbing, appliances, and family health.
What Homeowners Should Test and Consider
- Comprehensive Bacteriological Tests: Including total coliform, E. coli, and other indicator organisms to understand bacterial presence and levels specific to the residence.
- Water Source and Plumbing Inspection: To identify potential contamination pathways or biofilm hotspots.
- Monitoring After Treatment: To verify treatment effectiveness over time.
Sizing a Chemical Feed Chlorination System for Key West Homes
Given the bacterial challenges indicated in the FKAA system record for Key West, a chemical feed chlorination approach provides a documented solution for continuous bacterial control. The Total Well — Complete Chlorination Whole-Home System employs chemical feed technology tailored to manage bacterial presence effectively.
This system ships ready to configure and delivers continuous chlorination with specifications suitable for residential use: a grain capacity of 48,000, daily throughput of 17 gallons per day, and a flow rate capacity of 9 gallons per minute, using a tank measuring 10 by 54 inches. These metrics help ensure adequate contact time and chlorine residual for whole-home bacterial control.
Sizing the system correctly depends on household water usage, flow rates, and specific bacterial testing results. Homeowners in Key West should assess their average peak flow needs and water consumption patterns along with laboratory test data to select a system that maintains effective chlorination without excess chemical use.
Summary
Government records from EPA SDWIS confirm that the FKAA public water system serving Key West has documented bacterial issues, highlighting a potential need for bacterial control solutions for households. However, actual bacterial presence in a specific home’s water can only be established through targeted testing. The Total Well chemical feed chlorination system offers a documented, whole-home approach to managing bacteria continuously, with sizing guided by household water demand and test results. Taking informed steps ensures that residents maintain bacterially controlled water for health and comfort.
