Overview of Chlorination Standards

Public pools in Durham generally must maintain adequate free chlorine and combined chlorine levels and keep pH and turnover standards to meet state public health rules and local enforcement. The primary enforcement and inspection information for pools and spas in Durham is published by Durham County Environmental Health; operators should consult that office for inspection schedules, permit requirements, and local procedures [1]. State technical standards and minimum disinfectant requirements are set out by North Carolina Division of Public Health; operators should follow the state rules adopted for pool design, disinfectant residuals, testing frequency, and treatment systems [2].

Routine Testing & Recordkeeping

Routine testing expectations typically include measuring free chlorine, combined chlorine, cyanuric acid where used, pH, and temperature at prescribed intervals and retaining logs for inspection. The exact testing frequency, log format, and retention period are documented in the controlling statutes and local inspection guidance.

  • Keep written test logs for every operational day and retain as required by the inspecting authority.
  • Test frequency: follow the state and county instructions for hourly, daily, or weekly checks as applicable.
  • Post posted signage and required notices near the pool entrance per guidance.
Accurate, timestamped records are the primary evidence during inspections.
