� <br />EN HILLS <br />MEMORANDUM <br />DATE: February 13, 2012 <br />TO: Honorable Mayor and City Councilmembers <br />FROM: Jill Hutmacher, Community Development Director ��f <br />SUBJECT: Round Lake Update <br />At the May 16, 2011, City Council work session, representatives of the U.S. <br />Army and MPCA stated that the next draft of a feasibility study is expected to be completed in <br />fa112011 at the very earliest. Staff contacted Mike Fix, U.S. Army, for an update. <br />More than 130 samples were collected in January and February 2011, which provided much <br />more data than was previously available. The samples confirm contamination in the lake and <br />appear to indicate that backgraund or naturally occurring levels of inetals in the lake sediment <br />are higher than previously thought. Because the remediation goal was previously set at a level <br />that is below what now appears to be natural background conditions, the appropriate agencies <br />will need to consider these higher background levels of inetals when proposing a new <br />preliminary remediation goal. These decisions must be made prior to any redrafting of the <br />feasibility study. <br />Public meetings regarding the feasibility study are not likely to occur prior to slunmer 2012. <br />City of Arden Hills <br />February 13, 2012, City Council Meeting <br />Page 1 of 1 <br />
