Report contents—Information on Cryptosporidium, radon, and other contaminants.

(1) If the system has performed any monitoring for Cryptosporidium, and the results indicate that Cryptosporidium may be present in the source water or the finished water, the report must include:
(a) A summary of the results of the monitoring; and
(b) An explanation of the significance of the results.
(2) If the system has performed any monitoring for radon which indicates that radon may be present in the finished water, the report must include:
(a) The results of the monitoring; and
(b) An explanation of the significance of the results.
(3) If the system has performed additional monitoring which indicates the presence of other contaminants in the finished water, the department strongly encourages systems to report any results which may indicate a health concern. To determine if results may indicate a health concern, the department recommends that systems find out if EPA has proposed a National Primary Drinking Water Regulation or issued a health advisory for that contaminant by calling the Safe Drinking Water Hotline ( 800-426-4791). EPA considers detects above a proposed MCL or health advisory level to indicate possible health concerns. For the contaminants, the department recommends that the report include:
(a) The results of the monitoring; and
(b) An explanation of the significance of the results noting the existence of a health advisory or a proposed regulation.
