Operation of the new <br /> system will begin Thursday, May 19, 1994. (; cf' ~ ." .' r <br /> .A..lfLr:"~"- 'f,"r, <br /> . As you know, the purpose of the groundwater extraction system is to prevent <br /> movement of contaminated groundwater off of TCAAP. The extraction system consists of <br /> eight wells which remove contaminated water from the ground and pump the water to a <br /> central control house which allows the water flow and concentrations to be monitored. From <br /> the control house on TCAAP, the water is discharged to a sanitary sewer line. The water <br /> then is discharged into and treated by the Metropolitan Waste Control Commission Treatment <br /> Plant in St. Paul, Minnesota. <br /> We wish to thank all the parties that were involved in seeing this project through. <br /> Your participation was greatly appreciated. <br /> Sincerely, <br /> ~?~ <br /> Michael R. Fix <br /> Commander's Representative <br /> - <br /> . <br />
