Superfund Site Profile
The Vega Alta Public Supply Wells site is a public water supply well field in Vega Alta, Puerto Rico. The 50-acre area consists of six inactive and 15 active wells. The Puerto Rico Aqueduct and Sewer Authority (PRASA) has been responsible for operating and maintaining the public water supply system. The U.S. Geological Survey sampled the wells and surrounding areas and found volatile organic compounds (VOCs), potentially harmful contaminants that can easily evaporate into the air, in the groundwater and soil. PRASA shut down contaminated wells. Affected residences were hooked up to a new distribution system. In 1984, groundwater treatment equipment was installed at one of the contaminated wells.
The site’s long-term remedy is now in place. Groundwater treatment is ongoing. Under current conditions at the site, potential or actual human exposures are under control.
