Brayton Point Power Station

Download Data

Brayton Point Power Station has 6 groundwater monitoring wells, 4 of which have been polluted above federal advisory levels based on samples collected between November 23, 2015 and February 25, 2019. Groundwater at this site contains unsafe levels of arsenic, lithium and molybdenum.

Site description

Dynegy’s Brayton Power Station was a 1,600-MW coal plant in Somerset, Massachusetts on the south coast in Bristol County. Brayton opened in 1963 and retired its three coal-fired units in 2017. Commercial Development Co. (CDC) purchased the property at the start of 2018 with the intention of using it as a logistics, manufacturing, and support center for offshore wind and other industries. The plant has three ash polishing basins (Basins A, B, and C) that are regulated under CCR rule and were closed in 2017 following the facility’s closure. Brayton Point Power Station is among the U.S. Environmental Protection Agency's list of potential damage cases, indicating that coal ash disposal at the site has potentially polluted groundwater or surface water at levels which threaten human health and the environment.
