| Abstract | Long Description |
A Quality Assurance Project Plan is provided for a one-year monitoring program to evaluate chlorinated pesticide, polychlorinated biphenyl (PCB), total suspended solids (TSS), and turbidity concentrations in the Yakima River. This is the next step in an ongoing cleanup initiated through the Total Maximum Daily Load (TMDL) process required by the Clean Water Act for waterbodies that do not meet standards. The results will be used to: 1) assess the effectiveness of the 1997 lower Yakima River Suspended Sediment and DDT TMDL; 2) identify sources and quantify loadings of chlorinated pesticides, PCBs, TSS, and turbidity; 3) recommend numerical targets that will result in the river and its tributaries meeting water quality standards; and 4) propose wasteload and load allocations for sources, as appropriate. |
