Water quality.

CFR · 2024-01-01 · US · Title 9

(a) (b) (2) When the water is chemically treated, the chemicals shall be added so as not to cause harm or discomfort to the marine mammals. (3) Water samples shall be taken and tested at least weekly for coliform count and at least daily for pH and any chemical additives (e.g. chlorine and copper) that are added to the water to maintain water quality standards. Facilities using natural seawater shall be exempt from pH and chemical testing unless chemicals are added to maintain water quality. However, they are required to test for coliforms. Records must be kept documenting the time when all such samples were taken and the results of the sampling. Records of all such test results shall be maintained by management for a 1-year period and must be made available for inspection purposes on request. (c) (d)
