EPA added the Fibers Public Supply Wells site in Guayama Puerto Rico to the Superfund National Priorities List on September 1, 1983 because hazardous chemicals were found in the soil and ground water.  The superfund site located in Jobos contained a stand-by water supply for the Municipality of Guayama.  A synthetic fiber manufacturing plant operated near the site.  Contaminated water from the manufacturing plant was emptied into two ponds, resulting in the contamination of four of the five water supply wells in the area.  Samples taken from on-site wells showed that they were contaminated with volatile organic compounds (VOCs), which are potentially harmful contaminants that can easily evaporate into the air.  The soil was also contaminated with asbestos.  The site is located in an industrial and agricultural area with a population of approximately 41,000. 

As an immediate response, water supply wells were closed in 1982.  A total of 7,950 tons of asbestos containing materials were transported and disposed of in an authorized landfill in Puerto Rico.  A system that pumps out contaminated water and purifies it was installed in 1998.  A pipe was installed to drain the treated water.  A process called bioremediation, which uses organisms to return a contaminated environment to its original conditions, is being used to treat groundwater contaminants on-site premises.  Under current conditions at this site, potential or actual human exposures are under control.
