| Description | This report compares two independent water quality data sets from the Palouse and Yakima rivers. One set was collected by USGS using integrated sampling techniques and the other by Ecology using a grab sample method. In general, single point grab samples provided results similar to the more intensive and expensive integrated sampling when comparing concentrations. However, for sediment and total phosphorus, loads calculated from grab sample results were much lower than loads calculated from integrated sampling. If grab sample data are used to determine loads, the analyst should fully understand the potential limitations of this sampling method. |
