Concentrations and Loads of Cadmium, Lead, Zinc, and Nutrients Measured the During the 1999 Water Year Within Spokane River Basin, Idaho and Washington

by Paul F. Woods
Abstract

The EPA recently initiated a Remedial Investigation/Feasibility Study (RI/FS) of the Spokane River Basin in northern Idaho to evaluate contaminant realease, fate, and transport. In March 1998, the EPA asked the USGS to identify hydologic and water-quality studies the USGS might perform in support of the RI/FS. The study described in this report was conducted as Task 2, part of a multi-task program of data-collection activities to determine the nature and extent of trace-element contamination in the basin. The objective of Task 2 was to collect discharge and water-quality data during the 1999 water year in the Spokane River Basin in order to quantify trace-element and nutrient loads from multiple contributing source areas.
