Pool Water Purity
AUTHORITY: Implementing and authorized by the Radiation Protection Act of 1990 [420 ILCS 40/10].ILLINOIS EMERGENCY MANAGEMENT AGENCY AND OFFICE OF HOMELAND SECURITY
a) Pool water purification system shall be run sufficiently to maintain the conductivity of the pool water below 20 microsiemens per centimeter under normal circumstances. If pool water conductivity rises above 20 microsiemens per centimeter, the licensee shall take prompt actions to lower the pool water conductivity and shall take corrective actions to prevent future recurrences.
b) The licensee shall measure the pool water conductivity frequently enough, but no less than weekly, to assure that the conductivity remains below 20 microsiemens per centimeter. Conductivity meters shall be calibrated at least annually.
