EDWARDSVILLE • Benzene and other dangerous chemicals from the Wood River Refinery have contaminated properties and lowered property values in Roxana, according to a proposed class-action lawsuit filed this week on behalf of private property owners in the village against Shell Oil Co., WRB Refining LP and ConocoPhillips.

Filed by the Simmons Firm of Alton, the complaint follows a lawsuit with similar allegations that the firm filed in March of behalf of the Roxana village government. ConocoPhillips operates the refinery, which is located in Roxana and Hartford and owned by WRB Refining. Shell Oil Co. formerly owned and operated the refinery.
