System and method for controlling remediation cycles for the treatment of aquatic facility water

A system for controlling, confirming and documenting remediation of pathogens resistant to chlorine in water in an aquatic facility, the system comprising:

• a programmable controller;
• a chlorine dioxide sensor in fluid communication with the water and connected to the programmable controller;
• a chemical feed system in fluid contact with the water and connected to the programmable controller, wherein the chemical feed system is configured to supply chlorine dioxide to the water;
• the programmable controller is programmed to implement a remediation cycle and configured to calculate a chlorine dioxide Ct value of the water based on a concentration of the chlorine dioxide in the water;
• the programmable controller is programmed to sustain the concentration of the chlorine dioxide in the water until a targeted chlorine dioxide Ct value of the water is reached to achieve remediation of the water, wherein the remediation is at least a 3-log reduction of at least one pathogen resistant to the chlorine in the water;
• and
• the programmable controller is programmed to record and store the calculated chlorine dioxide Ct value to confirm that the remediation has been achieved or failed, when the calculated chlorine dioxide Ct value reaches the targeted chlorine dioxide Ct value remediation is achieved and when the targeted chlorine dioxide Ct value is not reached remediation has failed.
