Superfund investigation at a DOD site: Focus on remediation over investigation saves time and money

Marine Corps Air Station Yuma, Arizona, placed on the NPL in 1990, was faced in 1993 with a two year slippage in the FFA investigation schedule. An aggressive and innovative program was developed to achieve schedule recovery and focus on remediation over investigation. The remedial investigation was designed to rapidly evaluate the environmental condition of 18 sites and identify those sites that warrant remediation. The Navy, in partnership with the US EPA and Arizona Department of Environmental Quality, developed a strategy that eliminated the phased sampling approach and integrated CPT soil sample collection techniques, on-site mobile laboratory analysis, and geostatistical modeling to accelerate decision making during the field investigation. Soil samples were collected and rapidly analyzed by the on-site laboratory to determine the concentrations of selected classes of chemicals. The on-site laboratory analytical results were constantly monitored to coordinate the collection of additional samples as necessary to complete a generalized definition of contaminant plumes. Results were modeled geostatistically to predict the location of contaminant ``hot spots``. Evaluation of the ``hot spot`` data was conducted to determine if the concentrations represent an unacceptable level of risk that warrants remediation. The successful implementation of this investigation program resulted in: (1) recovery of over 20 months of schedule slippage; (2) a savings of an estimated $5 million in investigation funds; and (3) the ability to accelerate planning and implementation of remedial actions.
