qr Minnesota Pollution Control Agency <br /> August 21, 2002 <br /> Mr. Michael J. Pudil <br /> President and CEO <br /> Washington Scientific Industries, Inc. <br /> 18151 Territorial Rd <br /> Osseo, MN 55369 <br /> RE: Washington Scientific Site II, 2605 West Wayzata Boulevard,Orono <br /> MPCA Project Number VP 10021 <br /> Monitoring Report Approval Letter <br /> Dear Mr. Pudil: <br /> The Minnesota Pollution Control Agency(MPCA) staff in the Voluntary Investigation <br /> and Cleanup (VIC)Unit are working cooperatively with you to address concerns <br /> associated with contaminated ground water at the Washington Scientific facility located <br /> at the above referenced address in Orono (the Site). This Site is being administered <br /> through the VIC Unit as the Washington Scientific H Site with project number VP10021. <br /> The MPCA staff have reviewed the "Ground Water Sampling Results, June 2002 Event," <br /> (the Report)prepared by Peer Environmental &Engineering Resources, Inc. (PEER), <br /> dated June 20, 2002. <br /> The Report summarizes results from sampling of the two sentinel wells MW-13 and <br /> MW-14; and wells MW-4D, MW-10, MW-11, and MW-15. No volatile organic <br /> compounds (VOCs) were detected in MW-10, MW-11, MW-12, MW-13, or MW-14. <br /> The VOC 1,1-dichloroethane was detected in MW-15 at 2.6 micrograms per liter(ug/1) <br /> and the total VOCs for MW-4D screened adjacent to the receptor trench was <br /> approximately 1,000 ug/L. The overall results support that the VOC concentrations are <br /> relatively consistent and stable. The next ground water monitoring event is scheduled for <br /> June 2003. <br /> The Report proposes that dismantling and abandonment of the ground water remediation <br /> system be considered if ground water concentration trends remain stable after the next <br /> monitoring event in 2003. The Report is hereby approved. <br /> 520 Lafayette Rd.
