Ms. Linda Tanner • <br /> Delta No. 10-89-190 <br /> Page 2 <br /> August 31, 1989 <br /> Laboratories for analysis of Minnesota Department of Health Method 465B, methyl <br /> tertiary butyl ether, and total hdyrocarbons as gasoline. <br /> If the bedrock aquifer is found to be uncontaminated, the monitoring well will be <br /> abandoned and no further monitoring wells will be installed at the site. The <br /> horizontal extent of soil contamination will be defined based on data derived from <br /> soil borings. <br /> If the ground water is found to be only marginally contaminated, a survey will be <br /> conducted to determine potential receptors. Additional monitoring wells will not be <br /> installed at the site unless warranted. Soil borings will be used to evaluate the <br /> extent of soil contamination. <br /> All soil and ground water sampling will be performed in accordance with the <br /> specifications outlined in the Minnesota Pollution Control Agency letter of June 9, <br /> 1989. <br /> If you have any questions, please do not hesitate to contact me at 636-2427. <br /> Sincerely, <br /> DELTA ENVIRONMENTAL CONSULTANTS, INC. • <br /> Mary T.
