Site Description

The Pemaco Superfund site, located in a light industrial area in Maywood, CA, was used as a chemical blending facility and chemical distributor from the late 1940's until June 1991. Large quantities of chemicals were stored in aboveground storage tanks, underground storage tanks and 55- gallon drums. Spills from the tanks and drums resulted in the release of over 50 chemicals, including trichlorethene (TCE), tetrachloroethene (PCE), benzene, toluene, hexane, ethyl benzene, methylene chloride, and vinyl chloride, into the soil and groundwater.

Current Site Status and Cleanup Actions to Date

  • In August 1997, EPA dug up 31 underground storage tanks, and sent those plus several to a recycling center.
  • In August 1997, EPA also installed a soil vapor extraction system (PDF) (80 K, 2 pp) which treated 144,412 pounds of contaminated soil.
  • In February 2004, EPA completed the Remedial Investigation/Feasibility Study (RI/FS) for the site.
  • In April 2004, EPA requested public comment on its proposed cleanup plan.
  • EPA is developing its ROD based on comments received by the public. Presently, EPA plans to replace contaminated soil, plant vegetation, and treat contaminated groundwater.

Current Funding Status

  • To date, EPA has spent approximately $3,186,569.49 for investigation work at this site.
  • EPA has determined that this site does not pose an immediate threat to human health. Design work was not completed in Fiscal Year 2004; therefore, the site did not need construction funding. EPA expects that the site will be ready for construction funding in fiscal year 2005.
  • Once the ROD is signed, EPA has planned an expedited design schedule for the Pemaco site to prepare for remedy construction by the end of Fiscal Year 2005.
