All taps, hydrants, and other outlets shall be opened and left open until chlorine is noticeable by odor or testing in the water coming from each. Immediately close taps, hydrants, and other outlets. An effort shall be made to limit the amount of chlorinated

02510 - 8 water discharged from the taps, hydrants and other outlets. Heavily chlorinated water shall not be drained into streams, rivers, or lakes; rather open first those drains and hydrants that permit the longest travel time for the solution to reach surface waters.

D. Test Period:

1. Chlorinated water shall remain in the system a minimum of 24 hours, after which the system shall be examined by the CO for residual chlorine. Chlorine residual at the end of the 24-hour period shall be a minimum of 2 mg/1.

2. If the minimum residual is not found present, the system shall be drained and the disinfection testing shall be repeated. When disinfection is complete and approved by the CO, the system shall be flushed with potable water and the water leaving the lines shall have a free residual chlorine concentration no higher than 1 mg/l.

E. Bacteriological Examination: After the system has been disinfected as specified, the CO shall test the water for bacteriological contamination from representative points in the system. The coliform organisms shall be tested for presence/absence in accordance with State drinking water regulations. If coliform bacteria are present, testing shall be repeated in accordance with State drinking water regulations. If the report of this examination is unsatisfactory, the system shall be flushed and the disinfection procedure repeated until the results of bacteriological examinations are satisfactory.

F. The satisfactory quality of water delivered by the waterline should continue for a period of at least two full days, as demonstrated by laboratory examination of samples taken from taps along the system.

G. Bacteriological testing of the water system will be the responsibility of the Forest Service.

H. Where bacteriological water test indicates the presence of total coloform bacterial the

Contractor shall repeat the water system disinfection at no cost to the Government.

This work is incidental to other items in this contract and payment will be made under other items of the contract.
