Chapter 0400-45-01 - Public Water Systems
Section 0400-45-01-.15 - MONITORING OF CONSECUTIVE PUBLIC WATER SYSTEMS

(1) Each public water system is required to provide monitoring data to the Department as required by Rules 0400-45-01-.07 through 0400-45-01-.12, 0400-45-01-.21, 0400-45-01-.24, 0400-45-01-.26 and unregulated contaminant monitoring and reporting as required by the Environmental Protection Agency. Those public water systems which do not practice disinfection and which purchase all of their water from one or more public water systems that treats water may utilize the monitoring results obtained under Rules 0400-45-01-.08 through 0400-45-01-.12, 0400-45-01-.24, 0400-45-01-.26 and unregulated contaminant monitoring and reporting as required by the Environmental Protection Agency to demonstrate compliance if the public water system that treats water is subject to the referenced monitoring requirements. Consecutive systems that do not disinfect will be required to collect and analyze all samples that must be collected at the tap including asbestos. Those systems purchasing water and which practice disinfection shall not use the monitoring results obtained by another system for contaminants to be monitored in unregulated contaminant monitoring and reporting as required by the Environmental Protection Agency.

(2) Those public water systems which purchase all of their water and elect to perform the monitoring required by Rules 0400-45-01-.08 through 0400-45-01-.12, 0400-45-01-.21, 0400-45-01-.24, 0400-45-01-.26 and unregulated contaminant monitoring and reporting as required by the Environmental Protection Agency will have compliance with the MCL determined on the analytical results of its sampling.

(3) Those public water systems which purchase all their water and elect to use the analytical results of the system from which it purchases water shall be deemed to be in compliance with the monitoring and MCL requirements provided the seller of water is in compliance. Any violation of an MCL or monitoring requirement by the seller of water will constitute a violation for all systems which purchase water unless samples are taken as described in paragraph (2) of this rule.

(4) All public notification requirements as contained in Rule 0400-45-01-.19 are the responsibility of the individual public water system regardless of which public water system conducts the analysis.

(5) All public water systems must maintain records as required by Rule 0400-45-01-.20 of all analytical results which pertain to the system regardless of which system actually did the analysis.
