Superfund Site Report: CIDRA GROUND WATER CONTAMINATION
 
 
  • Site Description
    Stage of Clean-up: Remedial Assessment Not Begun

    The Cidra Ground Water Contamination site consists of a ground water plume with no identified source(s) of contamination. Puerto Rico Department of Health (PRDOH) ordered the following four public supply wells in Cidra to be closed due to contamination by tetrachloroethylene (PCE): Cidra Well 4 (Calle Padilla Final) in March 1996; Cidra Well 8 (Frente Cementerio) in October 1996; Cidra Well 3 (Planta Alcantarillado) in February 1999; and Cidra Well 6 (Calle Baldorioty) in August 2000. Other chlorinated volatile organic compounds (VOCs), including 1,1-dichloroethylene (1,1-DCE) and trichloroethylene (TCE), were also detected in the wells before they were closed. Cidra Ground Water Contamination site is located in Cidra, Puerto Rico. In June 2002, the U.S. Environmental Protection Agency (EPA) Region 2 Site Assessment Team (SAT) began an Expanded Site Inspection (ESI) of the Cidra Ground Water Contamination site. Confirmatory ground water samples were collected from the closed wells and 20 other active and inactive wells in Cidra. PCE was detected in the closed wells at concentrations ranging from 0.64 to 12 micrograms per liter (ug/L), and was also detected in two nearby industrial supply wells at the Zenith Laboratories site at concentrations as high as 4.1 ug/L.  More...
