Beverly has a former Nike missile site on L. P. Henderson Road, immediately east of the Beverly Municipal Airport. This site was in operation from March 1957 until August 1959, when the Army handed it over to the National Guard. It is now used by Beverly as a storage site and is under the scrutiny of many environmental organizations, as it and the surrounding areas—such as Casco Chemical—have polluted the groundwater, which could be potentially hazardous to the nearby Wenham Lake water supply.
