Lexington Manor was the original name of a subdivision in Liberty Twp., north of Millikin Road and east of Liberty-Fairfield Road. It was renamed Liberty Estates in 2004. Lexington Manor was built on a former skeet shooting range that closed in 1969. Residential building started in September 2001 by Ryland Homes on 26 acres bought in February 2000 by Lexington Manor Inc. In December 2002, the Ohio Environmental Protection Agency began investigating the 26-acre site for contamination from lead shot from shotgun shells. Elevated levels of lead and arsenic were found in the soil on 32 of the 46 lots in the subdivision. It was declared a U. S. EPA Superfund site in April 2003. In April 2004, the United States Environmental Protection Agency began removing land around 32 homes, totaling up to 23,000 tons of contaminated soil from the development. Appropriate cost was $2.5 million. Sept. 18, 2004 -- after the area was renamed Liberty Estates -- 29 of the 32 houses went on the market for an average price of $250,000.
A similar problem developed nearby in Fairfield Twp in the Brentwood Estates subdivision. A news report said "investigators believe arsenic-coated lead shot found on several lots was fired by patrons of a trap shooting business that had occupied the site before the subdivision was built in the 1970s."
