Lines of Evidence (LOEs) for Decision ID 13590 |
LOE ID: | 22975 |
Pollutant: | PCBs (Polychlorinated biphenyls) |
LOE Subgroup: | Pollutant-Tissue |
Matrix: | Tissue |
Fraction: | Fish fillet |
Beneficial Use: | Commercial or recreational collection of fish, shellfish, or organisms |
Number of Samples: | 1 |
Number of Exceedances: | 1 |
Data and Information Type: | PHYSICAL/CHEMICAL MONITORING |
Data Used to Assess Water Quality: | Samples were analyzed for the presence of 48 individual PCB congeners and Aroclors 1254 and 1260. Data evaluated were the sum of PCB congeners (total PCBs), reported as ng/g, wet weight. OEHHA and SWAMP recommend use of total PCBs for evaluating contamination.Total PCBs in the composite of channel catfish was 48.9 ng/L. The composite included 5 fish, with fork lengths 505-614 mm. |

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. The objective applies regardless of whether the toxicity is caused by a single substance or the interactive effect of multiple substances. |
Objective/Criterion Reference: | Central Valley Regional Water Quality Control Board. Water Quality Control Plan (Basin Plan) for the California Regional Water Quality Control Board - Central Valley Region |
Evaluation Guideline: | The California Office of Environmental Health Hazard Assessment (OEHHA) Fish Contaminant Goal for total PCBs in fish is 3.6 ng/g (3.6 ppb), wet weight, to protect human health. This concentration in fish tissue should not be exceeded, based on a total fish and shellfish consumption rate of 8 ounces (prior to cooking) per week (32 g fish/day) (OEHHA, 2008). This fish contaminant goal incorporates a maximum cancer risk level of one in a million (no more than one additional cancer in a population of one million people consuming these fish). |
Guideline Reference: | Development of Fish Contaminant Goals and Advisory Tissue Levels for Common Contaminants in California Sport Fish: Chlordane, DDTs, Dieldrin, Methylmercury, PCBs, Selenium, and Toxaphene |
Spatial Representation: | Samples were collected in the pond. |
Temporal Representation: | Samples were collected on August 29 and 31, 2002. |
Environmental Conditions: | PCBs have been used in the Feather River watershed in electric power generation and in other activities (CVRWQCB, 1987). |
QAPP Information: | Data quality: Acceptable.. Quality Control for all of the elements described in section 6.1.4 of the Policy was conducted in accordance with the Laboratory QAPP developed by the State of California Resources Agency Department of Water Resources (DWR, 2005).
