AES Puerto Rico has 5 groundwater monitoring wells, 3 of which have been polluted above federal advisory levels based on samples collected between August 08, 2017 and October 17, 2017. Groundwater at this site contains unsafe levels of sulfate, molybdenum, boron, lithium and selenium.Site description AES Puerto Rico LP operates a 454 MW coal-fired power plant located in the municipality of Guayama in the south coast of Puerto Rico. The Site has an approximate total area of 101 acres. The power plant uses bituminous coal for energy production, and generates coal combustion residuals in the form of coal ash. The CCR is converted to a manufactured aggregate known as Agremax that is stored in a temporary Agremax stockpile storage area that is located near the southern property boundary. The Agremax Storage Area is regulated under the CCR rule. You can find the industry-reported data here. For more information on the AES Puerto Rico, see EIP’s 2019 National Coal Ash Report.
