Stage of Clean-up: Construction Completed

Conditions at listing (September 1983): The Fibers Public Supply Wells serve 4,300 residents of Jobos, Puerto Rico. Two of the five wells in the field have been closed due to contamination from chlorinated solvents. One additional well with low-level contamination is still open. The U.S. Geological Survey detected the contamination in l977 during a survey of public water wells. The source has not yet been established. Status (June 1984): EPA is conducting a search for parties potentially responsible for wastes associated with the site.

Sources of Contamination:

• Inadvertent spill
• Lagoon disposal
• Other

Onsite monitoring well sampling results identified various VOLATILE ORGANIC COMPOUNDS (VOCS) believed to have originated from a nearby fiber manufacturer. The soil also is contaminated with various VOCS. Individuals may be at risk if direct contact is made with contaminated groundwater or soil. Closing the contaminated wells has reduced the potential for drinking contaminated groundwater.
