The 8-acre parcel on the Housatonic River has sat for more than 20 years, scraggly and undeveloped, and is still loaded with chlorinated organic compounds like dioxins and PCPs. The site’s owner, Community Development Corporation of South Berkshire (CDC), will hold a public information meeting at the Mason Librarytoday (Wednesday, Jan. 4), at 5:30 p.m. to provide current plans for the site and gather public input.
