A mass tort is a civil action involving numerous plaintiffs against one or a few corporate defendants. The tort may involve, for example, personal injuries suffered by numerous plaintiffs as a result of a defective product, or a mass disaster in which there were many injured persons, such as an airplane crash, or exposure of a large group of people to toxic chemicals or pharmaceuticals.
West Valley is a hamlet located within the town of Ashford in Cattaraugus County, New York, United States. Located at the intersection of Cattaraugus County Route 53 and State Route 240, the hamlet is home to West Valley Central School and the West Valley Demonstration Project, a nuclear cleanup facility. Because of the presence of a school district, a telephone exchange (716-942), and a post office located in (and named after) the hamlet, many people mistake West Valley to be the name of an actual town or village. However, it is not recognized by the U.S. Census Bureau, nor does it have any autonomous government separate from the town of Ashford.
