(b) The approved surface water quality shall
				  be monitored downstream of all surface water and groundwater under the
				  influence of surface water contributions and upstream of the first or only
				  point of disinfectant application, as follows:
(1) For fecal or total coliform density at
				  the following minimum frequency each week:
System size (persons

Samples/week
[LESS THAN EQUAL TO]
							 500

501-3,300

* Shall be taken on separate days.
(2) For fecal or total coliform density, once
				  every day the turbidity of the source water exceeds 1 NTU unless the State
				  Board determines that the system, for logistical reasons outside the system's
				  control, is unable to have the sample analyzed within 30 hours of collection.
				  If collected, these samples count toward the weekly coliform sampling
				  requirement; and
(3) For turbidity
				  at a minimum frequency of once every four hours. A supplier may substitute
				  continuous turbidity monitoring for grab sample monitoring if, at regular
				  intervals, it validates the accuracy of the continuous measurement using a
				  protocol approved by the State Board.
