The Blackburn & Union Privileges Superfund Site includes 22 acres of contaminated land and water in Walpole, Massachusetts. The contamination resulted from the operations of various industrial facilities dating back to the 19th century that exposed the site to asbestos, arsenic, lead and other hazardous substances. From about 1915 to 1936, a predecessor of W.R. Grace manufactured asbestos brake linings and clutch linings on a large portion of the property. From 1946 to about 1983, a predecessor of Tyco Healthcare operated a cotton fabric manufacturing business, which used caustic solutions, on a portion of the property.
