Data and Information Type: | PHYSICAL/CHEMICAL MONITORING |
Data Used to Assess Water Quality: | None of the 1 samples collected by the Surface Water Ambient Monitoring Program exceeded the evaluation objective for Zinc. |
Data Reference: | San Joaquin River SWAMP Monitoring Data - Northeast Basin |
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. This objective applies regardless of whether the toxicity is caused by a single substance or the interactive effect of multiple substances. (CRWQCB, 2006) Dissolved Zinc levels should not exceed the calculated limit based on the formula: Criteria Maximum Concentration=EXP((0.8473*LN(hardness))+0.884)*(0.978) (CTR) |

Beneficial Use: | Cold Freshwater Habitat |
Number of Samples: | 13 |
Number of Exceedances: | 0 |
Data and Information Type: | PHYSICAL/CHEMICAL MONITORING |
Data Used to Assess Water Quality: | The Central Valley Regional Water Quality Control Board Surface Water Ambient Monitoring Program collected 24 samples from January 2002 to December 2002. None of the 13 samples had pH values outside the acceptable range. |
Data Reference: | Monitoring Data from the Surface Water Ambient Monitoring Program (SWAMP), San Joaquin River Basin - 2007 Data Review |
Water Quality Objective/Criterion: | The pH of water shall not be depressed below 6.5,raised above 8.5, or changed at any time more than 0.5 units from normal ambient pH. Measurement of pH within the range of 6.5 and 8.5. A low pH has a value less than 6.5. |
