Abstract : A geophysical investigation was conducted at the Mustard Gas Burial Ground (MGBG) at the Naval Surface Warfare Center, Crane Division, Crane, IN. The MGBG, an approximately 2-acre area, is a former Solid Waste Management Unit. The objective of the investigation was to detect and delineate anomalies indicating the locations of buried structures, objects, or disturbed zones associated with past hazardous waste burial at the MGBG. The locations of these objects are needed so they can be excavated for removal to a permanent treatment or disposal site. Frequency and time domain electromagnetic (EM) along with magnetic survey methods were used at the MGBG. All the surveys performed at the MGBG indicated an anomalous area approximately 10 ft in diameter centered on Station 255 on Line 130. The estimated depth of the anomaly, based on results of the transient EM surveys, is 1 to 2 ft. The anomaly is presumed to be ferrous in nature since it was detected by the magnetometer. An additional, 2- to 3-ft diameter anomaly, caused by a small metallic object was detected by the transient EM surveys.
