Lines of Evidence (LOEs) for Decision ID 12557 |
LOE ID: | 22950 |
Pollutant: | Toxicity |
LOE Subgroup: | Toxicity |
Matrix: | Water |
Fraction: | Total |
Beneficial Use: | Warm Freshwater Habitat |
Aquatic Life Use: | Warm Freshwater Habitat |
Number of Samples: | 16 |
Number of Exceedances: | 0 |
Data and Information Type: | TOXICITY TESTING |
Data Used to Assess Water Quality: | None of the 16 samples tested with Ceriodaphnia dubia were toxic (survival endpoint) and violated the narrative toxicity objective. |
Data Reference: | Oroville Facilities Relicensing-FERC Project No. 2100. Contaminant accumulation in fish, sediments, and the aquatic food chain. Sacramento, CA: State of CA Department of Water Resources |
Water Quality Objective/Criterion: | All waters shall be maintained free of toxic substances in concentrations that produce detrimental physiological responses in human, plant, animal, or aquatic life. This objective applies regardless of whether the toxicity is caused by a single substance or the interactive effect of multiple substances (CVRWQCB, 2007). |
