GROUNDWATER MONITORING / SITE 1 LANDFILL COVER AND CLOSED / UST LONG TERM MONITORING  - NAVAL FACILITIES ENGINEERING COMMAND, SOUTHWEST, FORMER NAVAL FUEL DEPOT 

 

PROJECT DESCRIPTION

From the fall of 2007 to 2009, Citadel conducted four wet and dry season groundwater monitoring activities to support the Environmental Restoration Program at former Naval Fuel Depot at Point Molate, Richmond, California. 

Approximately 80 groundwater wells, two piezometers, surface water seeps, and oil/water separator effluent were sampled. Analyses included: TPH, TPH with silica gel preparation, PAHs, VOCs, SVOCs, dissolved metals, total metals, natural attenuation parameters, TDS, and soil gas was also sampled for methane. Data collected during these sampling events was integrated with previous year’s data to help delineate trends and support compliance and closure in accordance with regulatory requirements. 

Monthly and quarterly inspections of the Site 1 Landfill were conducted with a report being submitted every quarter. Recommendations for Site 1 landfill maintenance were implemented in 2008. USTs were inspected on a quarterly and bi-annual basis, the results of which were summarized in an annual UST monitoring report. Comprehensive groundwater elevation data was collected during every monitoring event, a new Work Plan and Sampling and Analysis Plan were developed in accordance with the Uniform Federal Policy for Quality Assurance Project Plan to optimize the monitoring program. A separate Work Plan was prepared and executed for a new well installed at the landfill with a shallower screened interval to detect possible free-product migration. In addition, landscape maintenance was conducted periodically to prevent vegetation over growth. 

The following activities were undertaken: 

  • Preparation of Health and Safety, Accident Prevention, Work, and Sampling and Analysis Plans;
  • Collection of water level measurements and parameters such as temperature, pH, and turbidity;
  • Clearing the well of free product using absorbent sock if necessary;
  • Collection of water samples using low flow technique and or a bailer;
  • Recording field data;
  • Handling, packing, and shipping of samples to the laboratory;
  • Managing chain-of-custody;
  • Validating laboratory data through a third party;
  • Management and disposal of industrial-derived waste;
  • Data analysis, report preparation, and GIS mapping;
  • Report submittal to regulatory agencies as per client requirement and instruction. 

In October of 2011, Citadel Environmental Services, Inc. acquired the environmental division of Barajas & Associates, Inc., which included the acquisition of key employees, as well as a multitude of experience in the public sector, including a recent seven (7) year, 20 Million dollar IDIQ contract with the Naval Facilities Engineering Command Southwest.
