- (a) Compliance with Env-Dw 705.01 shall be determined based on the analytical results obtained at each sampling point identified in the sampling schedule established pursuant to Env-Dw 708.01.
(b) For a PWS at which monitoring is conducted at a frequency greater than annually, the following shall apply:
- (1) The department shall determine compliance based on a running annual average, as defined in Env-Dw 100, of all samples collected at each sampling point;
- (2) If the running annual average of any sampling point is greater than the MCL, the PWS shall be out of compliance; and
- (3) If any sample result is more than 4 times the MCL at any sample point, the PWS shall be out of compliance.
- (c) For purposes of determining the running annual average, any sample below the detection limit shall be calculated as zero.
- (d) If monitoring is conducted annually or less frequently, the PWS shall be out of compliance if the level of a VOC contaminant at any sampling point is greater than the MCL. If confirmation samples are required by Env-Dw 712.04, the determination of compliance shall be based on the average of the initial and confirmation samples.
