Washington, District of Columbia requires operators of public pools and spas to follow local health rules and maintain proper chlorination and testing records. This guide summarizes where to find official requirements, how tests should be recorded, who enforces standards, and practical compliance steps for pool owners, managers and operators in Washington, District of Columbia.

Chlorination Standards & Testing

Operators must maintain disinfectant residuals and test water regularly, keep records of test results, and ensure treatment systems function correctly.

Follow DC Health directions and keep daily written logs of chlorine and pH tests.

Recordkeeping & Testing Frequency

Records should be available for inspection by inspectors and retained for the period required by the enforcing agency; the DC Health page does not list a specific retention period and it is not specified on the cited page.
