Data and Information Type: |
Fixed station physical/chemical (conventional plus toxic pollutants) |
Data Used to Assess Water Quality: |
A toxicity test was conducted using the upper water column sample on the mussel Mytilus galloprovincialis at one location for the Extent and Magnitude of Copper Contamination Study. Toxicity was not observed. |
Data Reference: |
Extent and Magnitude of Copper Contamination in Marinas of the San Diego Region, California. Technical Report 483. |
|
Water Quality Objective/Criterion: |
From the Basin Plan on toxicity, all waters shall be free of toxic substances that are toxic to, or that produce detrimental physiological responses in human, plant, animal, or aquatic life.
No individual pesticide or combination of pesticides shall be present in the water column, sediments or biota at concentration(s) that adversely affect beneficial uses. Pesticides shall not be present at levels which will bioaccumulate in aquatic organisms to levels which are harmful to human health, wildlife or aquatic organisms
(RWQCB, 2007). |
Objective/Criterion Reference: |
Water Quality Control Plan for the San Diego Basin (9). |
|
Evaluation Guideline: |
The threshold for toxicity was less than 80% development relative to the control test species (Schiff et al, 2006) |
Guideline Reference: |
Water Quality Standards; Establishment of Numeric Criteria for Priority Toxic Pollutants for the State of California; Rule. 40 CFR Part 131. U.S. Environmental Protection Agency, Region IX, Water Division, San Francisco, CA. |

|
Spatial Representation: |
One station was sampled in Santa Barbara Cove (M3) in Mission Bay. Water samples were collected at upper, middle and lower levels within the water column at each station however toxicity was only conducted on the upper samples. |
Temporal Representation: |
Samples were collected on August 15, 2005. |
Environmental Conditions: |

QAPP Information: |
Quality assurance conducted according to the Quality Assurance Project Plan for Marina Copper Monitoring Study. |
