EPA Superfund Program: UPJOHN FACILITY, BARCELONETA, PR

Superfund Site Profile

The Upjohn Facility site is located in Barceloneta, Puerto Rico. A pharmaceutical manufacturing plant operated at the 2-acre area. A leak in an underground storage tank contaminated wells on site. Soil and groundwater are contaminated with carbon tetrachloride, which is a colorless, nonflammable, vaporous toxic liquid used mainly as a refrigerant, fire extinguisher, cleaning fluid, solvent or insecticide. Metals in the groundwater are believed to have come from nearby industrial activity and from the construction of the stainless steel monitoring wells. The company installed groundwater monitoring wells and covered the area of the site with underground tanks to prevent rainwater from entering the soil. A vacuum extraction well was used to remove contamination from the soil. The population affected by the contamination was provided with alternative water supplies. Under current conditions at the site, potential or actual human exposures are under control.
