AES-PR Wellfield, Guayama, Puerto Rico

The AES-PR coal-fired co-generation plant required approximately 2 mgd of standby ground water supply from the Guayama area of Puerto Rico, area characterized by limited water supplies, intensive pumping by other industrial users and irrigators, seawater intrusion, and an adjacent EPA Superfund site. The firm oversaw the development and testing of 7 production and 5 monitoring wells, and performed aquifer analysis to determine the allowable yield. This ground water analysis was part of a larger project in which the firm prepared an analysis of all water sources to be used by the power plant, including a surface water reservoir, recycled wastewater and stormwater runoff.
