Louisville Food Service Water Testing Compliance Checklist

Louisville Water Quality Testing Requirements

The Louisville-Jefferson County Health Department requires food service establishments to test water used in food preparation, ice-making, and cooking. Establishments must obtain water from an approved public water system or maintain a private well with annual bacteriological testing (E. coli and total coliform analysis) conducted by a certified laboratory. Public water system users should document monthly residual chlorine testing at 0.5-2.0 mg/L using test strips or digital meters. All testing records must be maintained for a minimum of one year and provided to inspectors upon request during routine or complaint-based inspections.

Critical Inspection Focus Areas & Common Violations

Louisville inspectors prioritize water source documentation, chlorine residual levels, and temperature control for hot water systems (120°F minimum at hand-wash stations). Common violations include missing or outdated test records, chlorine levels outside acceptable ranges, water system cross-connections that pose backflow contamination risks, and failure to maintain backflow prevention devices with annual certification. Inspectors also verify that water used for sanitizing equipment meets coliform standards and that establishments using private wells conduct annual testing. Non-compliance can result in citations, operational restrictions, or closure orders depending on violation severity.

Documentation & Corrective Action Protocols

Maintain a dedicated water testing log with dates, test results, testing method, person performing the test, and corrective actions taken if standards are exceeded. If coliform bacteria or E. coli is detected in well water, the establishment must immediately cease food operations until a certified lab confirms safe water and a corrective treatment plan is implemented. For chlorine deficiencies, test more frequently and adjust chemical dosing; document all adjustments. Keep all laboratory reports, certification records for backflow prevention devices, and correspondence with the health department centralized and accessible during inspections. This documentation demonstrates due diligence and protects your establishment during regulatory review.
