Public Works Memorandum <br /> NO. 2012-60 <br /> DATE: September 5, 2012 <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: Ordinance Prohibiting The Use Of Groundwater As A Potable Water Supply <br /> By The Installation Or Use Of Potable Water Supply Wells Or By Any Other <br /> Method Within A Certain Area In The City Of Decatur <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 Classic Cleaners site located <br /> at 2474 North Main Street. <br /> PRIOR COUNCIL ACTION: <br /> There have been no prior Council actions regarding ground water contamination at 2474 North <br /> Main Street. <br /> Prior Council Action on Ground Water Ordinances: <br /> Since 2002, the City Council has authorized 18 ground water ordinances at various locations in <br /> the City. <br /> BACKGROUND: <br /> Ground Water Ordinance: <br /> City staff was contacted by Stantec Consulting Services, Inc. (letter attached), who represents the <br /> owner of Classic Cleaners located at 2474 North Main Street regarding their remediation efforts <br /> resulting from chemicals that have infiltrated into the ground from leaking tanks and machines <br /> due to the operation of a dry cleaning establishment at the site for many years. <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 for the properties identified on Exhibit A as having the maximum potential for ground <br /> water contamination from petroleum that was released from the site 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 depicted on Exhibit B 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 11 <br />
