<br />. <br /> <br />583 <br /> <br />POLYNUCLEAR AROMATIC HYDROCARBON STUDY <br />1997 Work Plan <br />U.S. Bureau of Land Management <br /> <br />Objectives: <br /> <br />1. Continue river water and sediment sampling. <br /> <br />2. Continue well water sampling. <br /> <br />3. GPS identification. <br /> <br />4. Reporting. <br /> <br />Methods: <br /> <br />Samples will be collected on the San Juan, Animas and La Plata rivers at 30 locations in the spring and fall. <br />These samples will be collected in spring in order to try to determine if there has been contaminant <br />deposition during the winter months and during late fall after irrigation is terminated. <br /> <br />Well water will be tested to determine presence of contaminants and will be based upon 1996 results and <br />will include wells that have not been remediated and now have lined disposal pits. <br /> <br />BLM has purchased a GPS that will be used to accurately determine the exact location of each location <br />sampled. This information will be provided for the Biology Committee for input into the GIS data file. <br /> <br />The annual report will be prepared and submitted for review by the Biology Committee by March 15,1998. <br /> <br />Budget: <br /> <br />Personnel <br /> <br />$15,000 <br /> <br />Sample analyses <br /> <br />30.000 <br /> <br />TOTAL <br /> <br />$45,000 <br /> <br />43 <br />
