Acute Toxicity-Rainbow Trout-survival Single Sample Maximum limit is 70 % survival and reported value was 0.0 % survival. |
The exact cause of the failure of the acute toxicity test is unknown, but it is believed to be related to the High Rate Clarifiers (HRCs) sludge not being thoroughly flushed out in the last cleaning cycle. One of the plant¿s sludge holding tank was out of service for 3 months. recurring cleaning of the HRCs have been added to the plant maintenance schedule which will include thorough flushing and disposal of sludge accumulated in the HRCs. |

ATOX |
Acute Toxicity-Rainbow Trout-survival Single Sample Maximum limit is 70 % survival and reported value was 40 % survival. |
The exact cause of the failure of the acute toxicity tests is not known, but it is believed to be related to dosing of cationic polymer for the High Rate Clarifier (HRC) system. To date, the SFPUC Water Supply and Treatment (WST) Operations Staff has invested significant time and resources into optimizing the HRC system for suspended solids removal, including startup testing and adjustments of dosing of polymers. The SFPUC will continue to conduct tests and investigate the cause until compliance is achieved. |
