SUBJECT: Results from Analyzing Metals in 1999 Spokane River
                 Fish and Crayfish Samples

Manchester Laboratory has completed their analyses for zinc, lead, and cadmium in the Spokane River fish and crayfish samples collected in July, August, and October of last year. Their data reports and quality assurance reviews are attached. These results, without the benefit of interpretation, are being promptly delivered to support the US Environmental Protection Agency Ecological Risk Assessement for the Spokane River.

Three tables are attached that summarize the information:

Table 1. Plan of Analysis (in Adobe pdf format)
Table 2. Location Information and Biological Data (in Adobe pdf format)
Table 3. Metals Concentrations (in Adobe pdf format)

A quality assurance project plan (Johnson, 1999) describes how the tissues were prepared. The ages of the fish are being determined from scales and other parts provided to John Sneva of the Department of Fish and Wildlife. The age data will not be available until sometime this spring.

Only enough crayfish were collected to analyze three whole body samples. Some data already exist on lead in crayfish muscle from samples collected in 1994 (Johnson, 1994).

If there are questions about these data, please call me at (360) 407-6766 or send email to arjo461@ecy.wa.gov.
