i. If the tank is isolated: A negative bacteriological analysis (coliform absent) from a certified drinking water lab; and after-entry chlorine residual and turbidity measurements that show no degradation when compared to the before-entry measurements.

ii. If the tank is not isolated: After-entry chlorine residual and turbidity measurements that show no degradation when compared to the before-entry measurements, as determined by the contracting officer’s representative. The contractor shall also collect and submit a sample from the tank for coliform analysis to a certified drinking water laboratory, the results of which (24-48 hrs later) must be negative (coliform absent).

Degradation is defined as a reduction in the chlorine residual by 0.2 mg/l or more, or a turbidity increase of 2 NTU or more.

b. If after the tank entry the water fails to meet these criteria, the contractor shall immediately:

i. Isolate the tank, reestablish the chlorine residual in the water in the tank, and collect subsequent bacteriological samples until the results are negative

(coliform absent); or,
