 The landfill was originally intended for biodegradable lawn waste such as tree limbs, but later it was reportedly used for other trash including construction and automobile waste and ash from the city incinerator on the east side of the park.In September 2005, the city made an agreement with WRS Infrastructure & Environment to clean up the site for $7.8 million.The plan was to excavate over 70,000 tons of contaminated soil and transport it to an EPA-approved landfill in Valdosta, Georgia, to remove three inches (76 mm) of sediment from of the stream and install a protective liner, and to place a clay cap over 5,750 square yards of the landfill.
