    Stage of Clean-up: Remedy Selected

    Conditions at Proposal (February 7, 1992): The Jet Propulsion Laboratory (JPL) covers 176 acres at 4800 Oak Grove Drive in Pasadena, Los Angeles County, California. The area is primarily residential with some light commercial operations. It is bordered on the east by the Arroyo Seco Dry Wash, on the west by a residential neighborhood, on the north by the San Gabriel Mountains, and on the south by an equestrian club and a Los Angeles County Fire Station. Approximately 120,800 people live within 4 miles of the site. The Army developed and operated JPL between 1945 and 1957; jurisdiction was transferred to the National Aeronautics and Space Administration (NASA) in 1958. The California Institute of Technology is under contract to NASA to conduct research and development at JPL in aeronautics, space technology, and space transportation. JPL's primary activities include exploration of the earth and solar system with automated spacecraft, and the design and operation of the Global Deep Space Tracking Network. Among the sources of hazardous substances at the site are numerous seepage pits, where liquid and solid wastes were reportedly disposed of; a "settling" chamber in the JPL storm drain system; contaminated soil excavated from part of the system; and an area where waste solvents were dumped into three holes.  More...

    Sources of Contamination:
    • Discharge to sewer/surface water
    • Inadvertent spill
    • Lagoon disposal
    • Other
    • Waste tank - below ground

  • Threats and Contaminants
    The groundwater contamination from the JPL has traveled off site and has affected several drinking water wells, including four municipal drinking wells belonging to the city of Pasadena and two drinking water wells belonging to the Lincoln Avenue Water Company. Thecontaminants are primarily VOCS including TRICHLOROETHYLENE and CARBON TETRACHLORIDE. People who ingest contaminated groundwater could be at risk.
