Sec. 46.
(a) Reporting requirements for tap water monitoring for lead and copper and for water quality parameter monitoring shall be as follows: (1) A water system shall report the following information for all tap water samples within the first ten (10) days following the end of each applicable monitoring period specified in sections 37 and 38 of this rule, that is, every six (6) months, annually, every three (3) years, or every nine (9) years: (A) The results of all tap samples for lead and copper, including: (i) the location of each site; and(ii) the criteria under: (AA) section 37(a)(3) through 37(a)(7) of this rule; or(BB) which the site was selected for the system's sampling pool.
