<P><FONT SIZE=+2><B>FORT ORD</B></FONT><P>CALIFORNIA</P><P>EPA ID# CA7210020676</P><P>EPA REGION 9</P><P>Monterey County</P><P>2 miles north of Monterey</P><P><B>Site Description </B><B><U> </U></B></P><P>The 29,440-acre Fort Ord site was established in 1917 by the U.S. Army as a maneuver area and field artillery target range. Prior to closing in September 1994, the base's primary mission was training infantry military personnel. Several areas of contamination exist on site. The facility contained leaking waste tanks, containers of waste oil and various automotive chemicals, chemical storage areas, oil-waste separators, target ranges, and landfills. One on-site area is a 150-acre landfill that was primarily used to dispose of residential waste, as well as small amounts of commercial waste. Other areas include a former fire drill pit, motor pool maintenance areas, small dump sites, and small arms target ranges. An 8,000-acre firing range, and other limited areas on-site, pose threats from unexploded ordnance. Approximately 40,000 people obtain drinking water from wells located within 3 miles of the site. The Salinas River alluvial basin, El Toro Creek, and Monterey Bay border the site. </P><P><B>Site Responsibility:</B></P><P>This site is being addressed through Federal actions.</P><P>NPL LISTING HISTORY</P><P>Proposed Date: 07/14/89</P><P>Final Date: 02/21/90</P><P><B>Threats and Contaminants </B><B><U> </U></B></P><P><A HREF="grndwtr.icn"><!IMG SRC="" ALT="Undisplayed Graphic"></A></P><P><A HREF="soil.icn"><!IMG SRC="" ALT="Undisplayed Graphic"></A></P><P>On-site groundwater and soil are contaminated with heavy metals, fuel hydrocarbons, and volatile organic compounds (VOCs). Contaminants have been detected in groundwater samples collected from Fort Ord and Monterey County Water District water supply wells. On-site soils in several vehicle maintenance and motor pool areas, and minor dump sites, have been contaminated with chemicals that spilled onto the ground. In addition, soils at the beach target ranges are contaminated with lead. Coming into direct contact with contaminated soils may pose a potential health threat to on-site workers, as well as employees of the Fort Ord Army base. Unexploded ordnances on an 8,000-acre firing range and limited on-site areas also pose health threats. Should site-related contaminants migrate off site through the soils or groundwater, the Salinas River, El Toro Creek, and Monterey Bay could be affected.</P><P><B>Cleanup Approach </B><B><U> </U></B></P><P>This site is being addressed in four stages: interim actions and three long-term remedial phases focusing on cleanup of the entire site, the Fritzsche Army Airfield practice fire pit, and the Fort Ord Landfill.</P><P><B>Response Action Status</B><B> </B><B><U> </U></B></P><P><A HREF="initial.icn"><!IMG SRC="" ALT="Undisplayed Graphic"></A><B>Interim Actions:</B> The Army initiated an investigation into the nature and extent of groundwater contamination. Preliminary findings showed an area of contamination known as the Fritzsche Army Airfield practice fire pit. As an interim action, the Army installed a groundwater and soil treatment system that has been operational since 1988. The contaminated groundwater is treated through carbon adsorption. A mixture of treated groundwater and necessary nutrients was sprayed on the contaminated soil adjacent to the groundwater treatment plant to facilitate the treatment of the soil. Soil treatment is nearing completion. The interim actions are focused on addressing primarily surface soils contaminated with fuels and waste oils from motor pools. Soils will be excavated and then treated at a treatment area using bioremediation or soil vapor extraction. In addition, in 1994, contaminated soil and debris, buried drums, and buried unexploded ordnance were removed.</P><P><A HREF="sitestdy.icn"><!IMG SRC="" ALT="Undisplayed Graphic"></A><B>Entire Site:</B> In 1990, the Army began further investigations into the nature and extent of on- and off-site soil and groundwater contamination, as well as any ecological or health threats that may be present. The investigation has identified two dump sites, firing ranges, and a vehicle maintenance area that require cleanup actions. The Army expects to complete the investigation and make final cleanup decisions in the fall of 1997.</P><P><A HREF="sitestdy.icn"><!IMG SRC="" ALT="Undisplayed Graphic"></A><B>Fritzsche Army Airfield Practice Fire Pit:</B> An investigation into the nature and extent of contamination in the Fritzsche Army Airfield practice fire pit began in 1990. A remedy is expected to be completed in mid-1995 that will establish groundwater cleanup standards for the area which must be met through the existing pump and treatment system. </P><P>Fort Ord Landfill: In 1994, the Army completed an investigation focusing on groundwater and soil contamination originating from the landfill. Monitoring wells were installed, surface soil samples collected, and soil gas samples taken. The EPA selected a remedy in the fall of 1994 that includes capping the landfill and installing a groundwater pump and treatment system. Design of the remedy is underway and expected to be completed in 1997.</P><P><B>Site Facts:</B> Fort Ord is participating in the Installation Restoration Program, a specially funded program established by the Department of Defense (DOD) in 1978 to identify, investigate, and control the migration of hazardous contaminants at military and other DOD facilities. In 1990, Fort Ord signed an Interagency Agreement with the EPA and the State of California to address on- and off-site contamination. Fort Ord was officially closed in 1994. The Army is considering proposals for re-use of the land, but intends to retain a portion of the base for a reserve enclave. Several parcels have already been transferred to the State University system. Cleanup activities are not affected by base closure activities, except to the extent that they are being accelerated to facilitate more rapid land transfers.</P><P><B>Environmental Progress </B></P><P><A HREF="progress.icn"><!IMG SRC="" ALT="Undisplayed Graphic"></A> <U> </U></P><P>The groundwater treatment system at the former fire pit and the removal of soil and debris have reduced the potential of exposure to contaminants while studies leading to the selection of final cleanup remedies are taking place at the Fort Ord site. </P><P><B>Site Repository </B></P><P><A HREF="filecab.cgm"><!IMG SRC="" ALT="Undisplayed Graphic"></A></P><P>Monterey County Free Libraries, Seaside Branch, 550 Harcourt Avenue, Seaside, CA 93955</P><ADDRESS>This page is maintained by the U.S. Environmental Protection Agency, Office of Emergency and Remedial Response.<BR>Web Page Revised on Aug 7, 1996</ADDRESS><P><A HREF="MAILTO:"></a>Content Comments: <i><a href="mailto:[email protected]">[email protected]</a></i><br>Design Comments: <i><a href="mailto:[email protected]">[email protected]</a></i></A></P><P><A HREF="0902778n.htm"><IMG SRC="bluppage.gif" WIDTH = 32 HEIGHT = 32 BORDER = 0 ALT="Previous Page"></A><A HREF="0902785n.htm"><IMG SRC="blunpage.gif" WIDTH = 32 HEIGHT = 32 BORDER = 0 ALT="Next Page"></A><A HREF="../usmap.htm"><IMG SRC="usmap2.gif" WIDTH = 32 HEIGHT = 32 BORDER = 0 ALT="See File"></A><P> |
