The Puget Sound Basin is a demographically complex region that supports a diversity of economic activities. A diverse group of opportunistic organisms is also associated with the development of the basin and are often controlled or eradicated with pesticides. These diverse chemicals exhibit a wide range of effects on the environment and many are toxic to organisms other than the intended targets. Pesticides that have the potential to migrate to the waters of Puget Sound or rivers within the basin are of major concern for their potential to cause harm to aquatic organisms. The report addresses the amount and distribution of contemporary pesticides used in the basin and then assesses the potential for these pesticides to migrate to the aquatic environment and induce toxic effects on aquatic organisms. This task is accomplished by defining pesticide uses, locating sources of available information, and surveying these sources to determine quantities used on a country-wide basis. Collated information characterizes the environmental fate and toxicity of pesticides. A tiered scoring method is used to rank pesticides and to determine the level of concern for individual pesticides.
