Data Used to Assess Water Quality: | Seventeen water samples were collected from Mokelumne River from August 2004 through September 2006, representing fifteen calculated 4-day average chlorpyrifos concentrations and five 1-hour average chlorpyrifos concentrations. Zero of the fifteen available calculated 4-day average chlorpyrifos concentrations exceeded the 4-day average chlorpyrifos criterion of 0.015 ug/L. Zero of the fifteen available 1-hour average chlorpyrifos concentrations exceeded the 1-hour average chlorpyrifos criterion of 0.025 ug/L. Two samples had concentrations less than quantitation limit (0.0254 ug/L), which is greater than the chlorpyrifos water quality criteria concentrations. Therefore, in accordance with Section 6.1.5.5 of the Listing Policy, the results for these samples were not used in this analysis. |
