<br />r.: "'''\ <br />~ I.. <br /> <br />SAN JUAN RIVER CONTAMINANT STUDIES <br />1997 WORK PLAN <br />U.S. Fish and Wildlife Service, Regions 2 and 6 <br /> <br />Background: <br /> <br />Field work for a synoptic survey of trace metals and inorganic constituents in the San Juan River was <br />completed in 1994 and the analytical chemistry results were completed 1995. A progress report was <br />completed in 1995 but did not include detailed analysis pending receipt of all data for the samples <br />collected and determination of potential needs for integration with other studies being completed <br />under this program. <br /> <br />During 1997 we intend to complete reporting of the synoptic study results, and assist in the <br />integration process. We also plan to have a few archived samples analyzed to complete the data set <br />as needed, based on recaptures of endangered fish in 1996 and 1997, and to opportunistically obtain <br />trace element data on salvaged fish as available. Funding requested is to partially offset the direct <br />undetermined costs of analytical needs, final summary report and integration activities, and <br />associated travel. <br /> <br />Objectives: <br /> <br />1. Incorporate data received since last progress report, interpret and prepare final report on the <br />synoptic studies. <br /> <br />2. Analyze a small quantity, as yet undetermined, of samples for trace metals as determined by <br />recaptures of marked endangered fish, and opportunistic sampling of wild endangered fish. <br /> <br />3. Assist in integration activities to assure that issues raised due to contaminant data are evaluated <br />across all studies. <br /> <br />Methods: <br /> <br />1. A final report will be prepared as per our milestone. <br /> <br />2. Coordinate with researchers on adult monitoring and razorback release studies to capture <br />opportunities and complete data sets, acquire samples, contract analysis and report results. <br /> <br />3. Provide evaluation of possible issues/areas where contaminants may be impacting endangered <br />fish and attend meetings or provide further assessments as required to assure integration of <br />contaminant issues with other program studies. <br /> <br />32 <br />
