Public Works Memorandum <br /> NO. 2011-48 <br /> DATE: July 8, 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 Decatur Ambulance Service Site Located <br /> at 461 West Wood Street <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 Decatur Ambulance Service <br /> site located at 461 West Wood Street. <br /> PRIOR COUNCIL ACTION: <br /> There have been no prior Council actions regarding ground water contamination at 461 West <br /> Wood Street. <br /> Prior Council Action on Ground Water Ordinances: <br /> Since 2002, the City Council has authorized 17 ground water ordinances at various locations in <br /> the City. <br /> BACKGROUND: <br /> Ground Water Ordinance: <br /> City staff was contacted by Bodine Environmental Services, Inc. who represents the owner of the <br /> Decatur Ambulance Service located at 461 West Wood Street regarding their remediation efforts <br /> resulting from petroleum releases infiltrating into the ground from a leaking underground fuel <br /> storage tank located at the site for many years. The leaking tank was owned by the Decatur <br /> Ambulance Service and used to fuel the company vehicles until it was removed in 1994 by order <br /> of the Illinois State Fire Marshall. Recent soil borings at the site have found contaminated soil <br /> with the potential for ground water contamination. <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.
