ZAPATA conducted surface geophysical surveys for groundwater investigations at the South Platte Wellfield Development Project near Brighton, Colorado. The main objectives were to map subsurface geologic formations and features (i.e. channels) that are important in controlling the occurrence of groundwater, particularly the depth to bedrock shale, and the potential of overlying alluvial sediments for groundwater resources. Both Frequency Domain Electromagnetic profiling and Time Domain EM sounding methods were employed.
An electromagnetic survey was conducted over 288 acres by ZAPATA at the Oklahoma Salt Plains National Wildlife Refuge, in Cherokee, Oklahoma. The objective of the work, completed for the United States Geological Survey, was to identify the presence of potential disposal pits containing metallic debris. All the electromagnetic geophysical surveys were conducted using Dual Coil and Triple Coil Geonics EM61-MK2 systems, and real-time kinematic (RTK) GPS navigation.
ZAPATA performed several mine subsidence investigations for DRMS in support of its Inactive Mine Reclamation Program (IMRP). These projects provided invaluable information for DRMS to design and implement a mitigation program. ZAPATA employed a suite of surface and downhole geophysical mapping methods delineating old mine workings beneath the residential area of the CCC.
On the site of a former landfill, ZAPATA conducted electrical (DC) resistivity imaging to determine the bedrock/overburden contact in order to identify possible buried stream channels. The geophysical data were very effective in mapping subsurface geologic formations and delineating sand and gravel channels incised into the bedrock.
