Public Works Memorandum <br /> NO. 2011-09 <br /> DATE: January 24, 2011 <br /> TO: Honorable Mayor McElroy and City Council <br /> FROM: Ryan P. McCrady, City Manager <br /> Richard G. Marley, P.E., Director of Public Works <br /> SUBJECT: Ground Water Ordinance for the Former One Hour Cleaners <br /> Located at 1133 West Grand Avenue <br /> SUMMARY RECOMMENDATION: <br /> It is recommended that the City Council approve the attached Ground Water Ordinance <br /> prohibiting the use of groundwater as a potable water supply for the former One Hour Cleaners <br /> located at 1133 West Grand Avenue. <br /> PRIOR COUNCIL ACTION: <br /> There have been no prior Council actions regarding ground water contamination at 1133 West <br /> Grand Avenue. <br /> Prior Council Action on Ground Water Ordinances: <br /> Since 2002, the City Council has authorized 16 ground water ordinances at various locations in <br /> the City. <br /> BACKGROUND: <br /> Ground Water Ordinance: <br /> City staff was contacted by Bonestroo, Inc. who represents the owner of the former One Hour <br /> Cleaners located at 1133 West Grand Avenue regarding their remediation efforts resulting from <br /> chemicals infiltrating into the ground from leaking tanks and machines due to the operation of a <br /> dry cleaning establishment at the site for many years. Records indicate that various owners have <br /> conducted dry cleaning businesses at 1133 West Grand since 1961. <br /> A Ground Water Ordinance is a tool used by the Illinois Environmental Protection Agency <br /> (IEPA)to remediate properties where soil and ground water under the site have been <br /> contaminated by chemicals. The ordinance prohibits the use of groundwater as a potable water <br /> supply within the area identified on Exhibit A as having the maximum potential for ground water <br /> contamination from chemicals used in the dry cleaning process that were released from the site <br /> over the years. <br /> The major benefit of a ground water ordinance is that it serves to keep contaminated water <br /> isolated underground and not allow it to be used for human consumption. The ground water use <br /> prohibition area identified on Exhibit A is served by the City's public water supply so the <br /> prohibition will not create a hardship on area residents or businesses. <br /> Page I 1 <br />
