Data Used to Assess Water Quality: |
Data are dissolved nickel measurements of grab samples collected through two monitoring programs. The first is the ongoing Regional Monitoring Program (RMP) in San Francisco Bay. The second set of data was from a special discharger-funded study to develop copper and nickel site-specific objectives (SSOs) that began in 2001. These data were taken throughout San Francisco Bay, but the bulk of the data are from the deepwater portion of the Bay. There were 107 individual dissolved nickel measurements from water samples taken in San Pablo Bay, and none of these measurements exceeded the objective. |

One of the 53 samples exceeded the guideline. All composite samples were comprised of Crassostrea gigas or 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 chlordane was calculated as the sum of the following chlordane isomers: cis- and trans-chlordane, cis- and trans-nonachlor, and oxychlordane. |

Data Used to Assess Water Quality: |
Water Board staff assessed Regional Monitoring Program data for San Pablo Bay to determine beneficial use support and results are as follows: 36 of 36 samples exceed the criterion for dieldrin. Thirty samples were discarded for being non-detect, unquantifiable or the reporting limit exceeding the water quality objective. |

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. |
Objective/Criterion Reference: |

|
Evaluation Guideline: |
The modified OEHHA Fish Contaminant Goal for dieldrin in fish tissue is 0.32 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: |
Thirty-six of the 50 samples exceeded the guideline. All composite samples were comprised of Crassostrea gigas or 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. Three samples were not used in the assessment because the laboratory data reporting limit(s) were above the objective and therefore the results could not be quantified with the level of certainty required by the Listing Policy. Laboratory replicates were averaged. |

None of the 35 samples exceeded the guideline. Composite samples were comprised of Crassostrea gigas or 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. 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. Laboratory replicates were averaged. |

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) |

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) |

Fourty-eight of the 52 samples exceeded the guideline. Composite samples were comprised of Corbicula fluminea, Crassostrea gigas, or 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 result for Station BD40 collected on 9/1/1998 was not a valid sample and so was not used 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 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. 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. Laboratory replicates were averaged. |

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): 206SNPBLO (San Pablo Bay (5)-206SNPBLO). |
Temporal Representation: |
Data for this line of evidence were collected between 2014-06-04 and 2014-07-03. 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. |

Data Used to Assess Water Quality: |
Water Board staff assessed Regional Monitoring Program - Status and Trends data for San Pablo Bay to determine beneficial use support and results are as follows: 0 of 1 samples exceeded the water quality threshold for Arsenic. |
Data Reference: |
Field, Tissue, Toxicity, WQ data from the California Environmental Data Exchange Network assembled for the 2024 Integrated Report in Region 2. |
|
SWAMP Data: |
Non-SWAMP |
|
Water Quality Objective/Criterion: |
The dissolved arsenic criterion continuous concentration (expressed as a 4-day average) to protect aquatic life in saline water is 36 ug/L. The conversion factor used to convert the total fraction criterion for arsenic to dissolved fraction criterion is 1. Therefore all data was considered to be representative of the dissolved fraction.
