SWMU 07 Quebrada Disposal Site

The Quebrada Disposal Site encompasses an area of approximately 1 acre. The landfill site was used between the early 1960s and late 1970s. An estimated 1,500 cubic yards (500 feet x 20 feet x 4 feet) of material was disposed at the site, including tires, sheet metal, drums, cans, bottles, batteries, and construction rubble. No known hazardous waste disposal occurred at this site. The site is currently covered by dense vegetation. A visual site survey was conducted by an unexploded ordnance (UXO) avoidance team, and a magnetometer survey was conducted within the proposed sampling area, as a safety measure prior to intrusive sampling during the 2000 expanded PA/SI. No live ordnance and explosives were identified at SWMU 7.  The Navy and the regulatory agencies agreed that the waste at SWMU 7 poses an unacceptable uncertainty regarding a potential future source of contamination and, therefore, should be removed. The wastes were removed and properly disposed of by the end of 2008. Confirmatory sampling was performed after the removal actions were completed, to ensure that the site is left in a manner that is protective of human health and the environment. Past Investigations and Actions Environmental Baseline Survey (2000) Expanded Preliminary Assessment/Site Investigation (2000) Remedial Investigation (2003) Engineering Evaluation/Cost Assessment for public comment (2005-2006) Removal Actions (2008 thru 2009) Current Site Status Confirmatory sample data are being used in post-removal human health and ecological risk assessments.
