"ity of <br /> <br />iver <br /> <br />MEMORANDUM <br /> <br />TO: <br /> <br />Pat Klaers, Mayor and <br />City Council <br /> <br />FROM: <br /> <br />Steve Rohlf- Building and <br />Zoning Administrator <br /> <br />DATE: October 23, 1995 ~'/~ <br /> <br />SUBJECT: Phase I and II Environmental Audit <br /> of the Cass Property <br /> <br />The city staff in cooperation with the city's environmental consultants, B.A. <br />Leasch and Associates, have completed a Phase I and a partial Phase II <br />environmental audit on the Cass property. The Phase I showed no signs or <br />history of any past structures being located on the property. The Phase I also <br />did not reveal any pipelines, transformers or obvious signs of dumping. <br />However, the Phase I did raise enough concern to warrant a partial Phase II <br />environmental audit. <br /> <br />The following Phase II work was completed on the Cass property: <br /> <br />1. The inspection of J & J Machine facility, which came back OK. <br /> <br />The sampling of one of the city sludge site monitoring wells <br />for RCRA Metal, which came back OK. <br /> <br />The installation of three monitoring wells on the Cass property <br />to determine the direction of ground water flow, document the <br />pre-existing nitrate level and to monitor the T.J. Hopkins site <br />for contamin ation. <br /> <br />Sampling of the monitoring wells mstMled showed the ground <br />water flow, to be to the southeast instead of the southwest as <br />expected. This actually is a good situation because Burlington <br />Northern Rnilroad and the T.J. Hopkins facility lie to the south <br />and southeast of the Cass property, therefore, they are not a <br />concern. Ssmpling of these wells a/so indicated existing <br />nitrates on the Cass property; probably from farming. <br />However, they are at low levels. <br /> <br />13065 Orono Parkway · P.O.
