Reconnaissance Investigation of Water Quality, Bottom Sediment, and BiotaAssociated with Irrigation Drainage in the Columbia Basin Project, Washington, 1991-92

摘要

The purpose of this report is to describe the results of a reconnaissanceinvestigation of the CBP too determine if irrigation drainage has affected or has the potential to adversely affect human health, fish, and wildlife populations, or other beneficial water uses. Water, bottom-sediment, and biological samples were collected from several sites within the CBP from November 1991 to July 1992, and analyzed for concentrations of selected inorganic and organic compounds. These concentrations were then compared with various water-quality criteria or standards, published literature values, and baseline values for the study area or for other locations.
