RFI investigative activities began in January 2002 to determine if any impacts exist at the Facility. Supplemental investigations were completed, as required, based upon the results of the initial sampling activities.

On-Site RFI investigation activities include the following:
• Soil sampling at the surface and below ground
• Groundwater sampling
• Sediment sampling
• Surface water and spring sampling
• Evaluation of on-Site geology
