Subchapter 7 - Water Monitoring
Section 310:225-7-2 - Possible source contamination

(a) Where a bottled water plant operator, water dealer or regulatory agency knows or has reason to believe that a contaminant not otherwise monitored is present in the source water because of a spill, release of a hazardous substance or otherwise, and its presence would create a potential health hazard to consumers, the plant operator or water dealer upon receipt of such information shall monitor the source water for said contamination.

(b) Detection of contaminant(s) in source monitoring required pursuant to this Subchapter shall be followed immediately by a program of periodic monitoring to confirm the presence in the source water of said contaminant(s). If such listed unregulated contaminant(s) is confirmed to be present in the source water at a concentration that exceeds a published U.S. EPA Health Advisory, or a U.S. EPA or Department Action Level for drinking water, the plant operator or water dealer shall employ appropriate treatment techniques to remove or to reduce said contaminant in the product water below said concentration and shall employ a program of periodic monitoring for said contaminant in the source water until such time as said contaminant is not detectable in the source water.
