Publication Summary

This is the study plan for measuring perfluorinated compounds in Washington rivers and lakes.

This Quality Assurance (QA) Project Plan is provided for analyzing perfluorinated compounds (PFCs) in selected rivers and lakes in Washington State. PFCs are an emerging contaminant used as a processing aid in the manufacture of fluoropolymers which have many useful properties such as the ability to repel oil, water, and grease.

The goal of the study is to evaluate the spatial distribution of PFCs in Washington State and to determine concentrations at which these contaminants are found. The data will be used in the preparation of a future Chemical Action Plan that will identify steps the state may take to further reduce the threat of PFCs in the environment.

During the spring and fall, PFC concentrations in water will be determined at 14 freshwater locations and from effluent at 4 wastewater treatment plants. Fish muscle, livers, and eggs will be analyzed at 8 of the freshwater locations. Additionally, PFC concentrations in osprey eggs will be determined from nests along the lower Columbia River. Sampling will be conducted from May - November 2008.

Each study conducted by the Washington State Department of Ecology must have an approved QA Project Plan. The plan describes the objectives of the study and the procedures to be followed to achieve those objectives. After completion of the study, a final report describing the study results will be posted to the Internet.
