The results did not exceed the guideline. Data were reported on a dry weight basis and were converted to a wet weight basis by multiplying the dry-weight concentration by a factor of 1 minus the percentage of moisture content expressed as a decimal. Chlordane result was calculated by summing the results for chlordane isomers: cis- and trans-nonachlor, alpha- and gamma-chlordane, and oxychlordane. |

QAPP Information: |
Samples were collected as part of the State Water Board's Mussel Watch Program which is a part of the National Oceanic Administration's (NOAAs) National Status and Trends (NS&T). Mussels are shipped to NOAAs contract labs for analysis of trace constituents and mussel condition. Analytical protocols follow those approved by NOAAs NS&T Program Additional background information can be found at:

Data and Information Type: |

Data Used to Assess Water Quality: |
None of the 51 samples exceeded the guideline. All composite samples were comprised of Mytilus californianus. Data were reported on a dry weight basis and were converted to a wet weight basis by multiplying the dry-weight concentration by a factor of 1 minus the percentage of moisture content expressed as a decimal. Laboratory replicates were averaged. Total DDT was calculated as the sum of 4,4'- and 2,4'- isomers of DDT, DDE, and DDD. |

Evaluation Guideline: |
The modified OEHHA Fish Contaminant Goal for total DDT in shellfish tissue is 23 ppb. This screening level assumes an average body weight of 70 kg and a consumption rate of 21 g/day for a 30 year exposure over a 70-year lifetime. This constituent is a carcinogen therefore the risk level is set to one in a million. (Brodberg, R.K., and G.A. Pollock, 1999; Klasing, S., and R. Brodberg, 2008) |

Data Used to Assess Water Quality: |
None of the 34 samples exceeded the guideline. All composite samples were comprised of Mytilus californianus. Data were reported on a dry weight basis and were converted to a wet weight basis by multiplying the dry-weight concentration by a factor of 1 minus the percentage of moisture content expressed as a decimal. Laboratory replicates were averaged. If a dry weight result did not have a corresponding moisture result for conversion to wet weight, the sample was not included in the assessment. |

Evaluation Guideline: |
The modified OEHHA Fish Contaminant Goal for polychlorinated biphenyls in fish tissue is 2.6 ppb. This screening level assumes an average body weight of 70 kg and a consumption rate of 32 g/day for a 30 year exposure over a 70-year lifetime. This constituent is a carcinogen therefore the risk level is set to one in a million. A cooking reduction factor of 1 is applied for skin-off fillets. (Klasing, S., and R. Brodberg, 2008) |

Data Used to Assess Water Quality: |
Fourty-nine of the 51 samples exceeded the guideline. Composite samples were comprised of Mytilus californianus. Data were reported on a dry weight basis and were converted to a wet weight basis by multiplying the dry-weight concentration by a factor of 1 minus the percentage of moisture content expressed as a decimal. Laboratory replicates were averaged. Total PCB was assessed for as follows: PCB aroclors and congeners were summed separately and the sum that yielded the highest value was used for the assessment. The results for Station BC61 collected on 5/8/1997 were not valid samples and so were not used in the assessment. |

Evaluation Guideline: |
The modified OEHHA Fish Contaminant Goal for polychlorinated biphenyls in shellfish tissue is 3.9 ppb. This screening level assumes an average body weight of 70 kg and a consumption rate of 21 g/day for a 30 year exposure over a 70-year lifetime. This constituent is a carcinogen therefore the risk level is set to one in a million. (Brodberg, R.K., and G.A. Pollock, 1999; Klasing, S., and R. Brodberg, 2008) |

Although a total of 1 samples were collected, 1 of these samples were not included in the assessment because the laboratory data reporting limit(s) was above the water quality threshold and therefore the results could not be quantified with the level of certainty required by the Listing Policy Section 6.1.5.5. |

This constituent is a carcinogen therefore the risk level is set to one in a million. A cooking reduction factor of 1 is applied for skin-off fillets. (Klasing, S., and R. Brodberg, 2008) |

Evaluation Guideline: |
The modified OEHHA Fish Contaminant Goal for polychlorinated biphenyls in fish tissue is 2.6 ppb. This screening level assumes an average body weight of 70 kg and a consumption rate of 32 g/day for a 30 year exposure over a 70-year lifetime. This constituent is a carcinogen therefore the risk level is set to one in a million. A cooking reduction factor of 1 is applied for skin-off fillets. (Klasing, S., and R. Brodberg, 2008) |

Data Used to Assess Water Quality: |
Water Board staff assessed Regional Monitoring Program - FISH data for San Francisco Bay, Central to determine beneficial use support and the results are as follows 0 of the 2 samples exceeded the water quality threshold for Selenium. Data were collected for 3 fish species (1 composite(s) of Shiner Surfperch each composed of 19 fish per composite, 2 composite(s) of Shiner Surfperch each composed of 20 fish per composite, 10 composite(s) of White Croaker each composed of 5 fish per composite). |
Data Reference: |
Tissue data from the California Environmental Data Exchange Network assembled for the 2024 Integrated Report in Region 2. |

Water Quality Objective/Criterion: |
Water Quality Control Plan for the San Francisco Bay Basin: Controllable water quality factors shall not cause a detrimental increase in concentrations of toxic substances found in bottom sediments or aquatic life. Effects on aquatic organisms, wildlife, and human health will be considered. |

Evaluation Guideline: |
The OEHHA Fish Contaminant Goal for selenium in fish tissue is 7.4 ppm. This screening level assumes an average body weight of 70 kg and a consumption rate of 32 g/day. A background dietary consumption rate of 0.114 mg/day is applied for this micronutrient. (Klasing, S., and R. Brodberg, 2008) |
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: |
Data were collected from 1 station(s). Station Code(s): 203OAKLND (Oakland (2)-203OAKLND). |
Temporal Representation: |
Data for this line of evidence were collected between 2014-05-05 and 2014-05-08. When composited fish were collected over multiple days, the first day of fish collection was used as the sample date in the LOE, both for LOE writing, and for averaging period purposes. |
