Section 335-7-11-.09 - Invalidation Of Lead Or Copper Tap Water Samples

A sample invalidated under this rule does not count toward 90th percentile levels or toward meeting minimum monitoring requirements.

(a) A sample may be invalidated for one of the following reasons.

1. The laboratory establishes that improper sample analysis caused erroneous results.

2. The State determines that the sample was taken from a site that did not meet the site selection criteria of this rule.

3. The sample container was damaged in transit.

4 There is substantial reason to believe that the sample was subject to tampering.

(b) The system must report the results of all samples to the State and all supporting documentation for samples the system believes should be invalidated.

(c) The water system must collect replacement samples for any samples invalidated under this rule if, after the invalidation of one or more samples, the system has not collected the minimum number of samples. Any such replacement samples must be taken as soon as possible, but no later than 20 days after the date the State invalidates the sample or by the end of the applicable monitoring period, whichever occurs later. Replacement samples taken after the end of the applicable monitoring period shall not also be used to meet the monitoring requirements of a subsequent monitoring period. The replacement samples shall be taken at the same locations as the invalidated samples or, if that is not possible, at locations other than those already used for monitoring during the monitoring period.
