<strong>Dames</strong> & <strong>Moore</strong> Job #I 7693-005-01 9<br />

he standard data quality review of 17 surface water samples and 3 equipment blanks collected<br />

from April 30 to May 5, 1998 has been completed. The samples were analyzed at the Analytical<br />

Resources, Incorporated (ARI) laboratory in Seattle, Washington for total recoverable and dissolved<br />

metals by EPA Methods 6010A and 200.8 modified (including the following metals: aluminum, arsenic,<br />

barium, beryllium, cadmium, calcium, chromium, copper, iron, lead, magnesium, manganese,<br />

molybdenum, nickel, potassium, silver, sodium, zinc) and hardness by EPA Method 6010A calculation. In<br />

addition, samples were also analyzed for the following: alkalinity by Standard Method 2320, total dissolved<br />

solids (TDS) by EPA Method 160.1, total suspended solids (TSS) by EPA Method 160.2, and sulfate by<br />

EPA Method 375.2. Select samples were analyzed for total petroleum hydrocarbons (diesel and gasoline<br />

range) by Washington State Department of Ecology TPH methods. Samples were analyzed for low-level<br />

lead by Frontier Geosciences in Seattle, Washington. The low-level lead results are not included in this<br />

report as they were provided separately and validated under separate cover memo. The analyses were<br />

performed in accordance with the methods specified in EPA Test Methods for Evaluating Solid Waste,<br />

January 1995, EPA Methods for Chemical Analysis of Water and Wastes, March 1983. Standard<br />

Methods for the Examination of Water and Wastewater, 18th edition, 1992, and Washington State<br />

Department of Ecology Total Petroleum Hydrocarbons Methods, April 1992. A validation package<br />

containing method associated QAIQC data and summarized sample data was provided by the laboratory.<br />

The following samples are associated with laboratory work orders ARI# W219 and W221:<br />
