Okla. Admin. Code § 252:624-5-2

Current through Vol. 41, No. 19, June 17, 2024
Section 252:624-5-2 - Testing prior to placing minor public water supply systems into operation
(a)Water samples. Following the disinfection and flushing procedure outlined in OAC 252:624-5-1, water samples shall be collected from the distribution system at the tap located the farthest distance from the wellhead on two (2) consecutive days and submitted to a laboratory for bacteriological analysis.
(b)Testing results.
(1)Total coliform positive test results. If either of the sample results required in (a) of this Section come back positive for coliform bacteria, then the disinfection and flushing procedure outlined in OAC 252:624-5-1 shall be repeated. When two (2) consecutive days of coliform negative samples cannot be obtained despite repeated disinfection efforts, then full-time disinfection will be mandatory.
(2)Fecal coliform positive. If any of the sample results required in (a) of this Section come back positive for fecal coliform, then a retake sample must be submitted for analysis at a laboratory. If the results of a retake sample come back positive for fecal coliform, then the source water cannot be used for a minor public water supply well. If additional cleaning and disinfection of the well results in safe bacteriological samples, DEQ may evaluate the sampling history to determine if the well is approvable as a minor public water supply well .
(3)Total coliform negative test results. If the sample results required in (a) of this Section come back negative for coliform bacteria for two (2) consecutive days, then the minor public water supply system may be put into operation after receiving approval from DEQ following the required final inspection [see OAC 252:624-1-4(h) (relating to final inspections)].
