All waters shall be maintained free of toxic substances in concentrations that are lethal to or that produce significant alterations in population or community ecology or receiving water biota.

Objective/Criterion Reference: |
Water Quality Control Plan (Basin Plan) San Francisco Bay Basin (Region 2) |
|
Evaluation Guideline: |
The California Stream Condition Index (CSCI) is a biological scoring tool that helps aquatic resource managers translate complex data about benthic macroinvertebrates found living in a stream into an overall measure of stream health. The CSCI score is calculated by comparing the expected condition with actual (observed) results (Rehn, A.C. et al., 2015). CSCI scores range from 0 (highly degraded) to greater than 1 (equivalent to reference). CSCI scoring of biological condition are as follows (per the scientific paper supporting the development of the CSCI scoring tool): greater than or equal to 0.92 = likely intact condition, 0.91 to 0.80 = possibly altered condition, 0.79 to 0.63 = likely altered condition, less than or equal to 0.62 = very likely altered condition. Sites with scores below 0.79 are considered to have exceeded the water quality objective for the aquatic life beneficial use. |

Evaluation Guideline: |
The California Stream Condition Index (CSCI) is a biological scoring tool that helps aquatic resource managers translate complex data about benthic macroinvertebrates found living in a stream into an overall measure of stream health. The CSCI score is calculated by comparing the expected condition with actual (observed) results (Rehn, A.C. et al., 2015). CSCI scores range from 0 (highly degraded) to greater than 1 (equivalent to reference). CSCI scoring of biological condition are as follows (per the scientific paper supporting the development of the CSCI scoring tool): greater than or equal to 0.92 = likely intact condition, 0.91 to 0.80 = possibly altered condition, 0.79 to 0.63 = likely altered condition, less than or equal to 0.62 = very likely altered condition. Sites with scores below 0.79 are considered to have exceeded the water quality objective for the aquatic life beneficial use. |

TOXICITY TESTING |
Data Used to Assess Water Quality: |
0 of the 1 samples collected by BASMAA RMC Monitoring in WY2017 for Ward Creek subwatershed (Alameda County, tributary to Old Alameda Creek) exhibited toxicity. A sample may have multiple toxicity test results, but will only be counted once. A sample is defined as being collected on the same day and the same location. The following organisms and parameters were utilized for the toxicity tests: Chironomus dilutus for Survival, Pimephales promelas for Survival. |

Water Quality Objective/Criterion: |
All waters shall be maintained free of toxic substances in concentrations that are lethal to or that produce other detrimental responses in aquatic organisms. Detrimental responses include, but are not limited to, decreased growth rate and decreased reproductive success of resident or indicator species. There shall be no acute toxicity in ambient waters. Acute toxicity is defined as a median of less than 90 percent survival, or less than 70 percent survival, 10 percent of the time, of test organisms in a 96-hour static or continuous flow test. There shall be no chronic toxicity in ambient waters. Chronic toxicity is a detrimental biological effect on growth rate, reproduction, fertilization success, larval development, population abundance, community composition, or any other relevant measure of the health of an organism, population, or community. Attainment of this objective will be determined by analyses of indicator organisms, species diversity, population density, growth anomalies, or toxicity tests (including those described in Chapter 4), or other methods selected by the Water Board. The Water Board will also consider other relevant information and numeric criteria and guidelines for toxic substances developed by other agencies as appropriate. |
Objective/Criterion Reference: |
Water Quality Control Plan (Basin Plan) San Francisco Bay Basin (Region 2) |
|
Evaluation Guideline: |
The sample is toxic when the response of the organisms exposed to the sample is significantly different (worse) than the response of the organisms exposed to the laboratory control based on statistical hypothesis testing. An exceedance is counted when the significant effect code is “Significant; Less Similarity,” which means that the sample result is significantly different than the control result, and the percent effect is greater than the evaluation threshold. The default evaluation threshold is 20% unless otherwise stated. |

0 of the 1 samples collected by BASMAA RMC Monitoring in WY2017 for Ward Creek subwatershed (Alameda County, tributary to Old Alameda Creek) exhibited toxicity. All samples met the requirements of the State Policy for Water Quality Control: Toxicity Provisions. This includes utilizing the Test of Significant Toxicity (TST) and using toxicity testing methods provided in the Provisions to assess water column toxicity. A sample may have multiple toxicity test results, but will only be counted once. A sample is defined as being collected on the same day and the same location. The following organisms and parameters were utilized for the toxicity tests: Hyalella azteca for Survival, Selenastrum capricornutum for Total Cell Count, Ceriodaphnia dubia for Young/female, Pimephales promelas for Biomass (wt/orig indiv). |

Objective/Criterion Reference: |
Water Quality Control Plan (Basin Plan) San Francisco Bay Basin (Region 2) |
|
Evaluation Guideline: |
Attainment of the water quality objective is demonstrated by conducting aquatic toxicity testing, analyzing the data using the TST statistical approach, and rejecting the null hypothesis. The null hypothesis is the following general statement: the ambient water is toxic because the response (e.g., survival, reproduction, growth) of the test organisms in the ambient water sample is less than or equal to 75 percent (chronic) or 80 percent (acute) of the test organisms’ response in the control water sample. The alternative hypothesis is the following general statement: the ambient water is not toxic because the of the test organisms in the ambient water sample is greater than 75 percent (chronic) or 80 percent (acute) of the test organisms’ response in the control water sample. |
