Utility mapping	Depth to water table
Underground storage tank locating	Fault zone mapping
Unexploded ordnance (UXO)	Sinkholes
Voids/tunnels	Soil properties
Landfill delineation	Dam/lagoon leakage
Dissolved contaminant plume mapping	Saltwater intrusion
Soil salinity	Buried drum delineation
Landfill boundary mapping	Septic tank/system locating
Landfill bottom evaluation	Abandoned well locating
Archaeological investigations	Trench boundary mapping
Bedrock rippability	Grave locating
Light (Non-aqueous) Phase Liquid Contaminant (LNAPL) Plume Mapping	Electromagnetic field (EMF) mapping
Pile integrity testing	Crosshole surveys
Power system grounding	Engineering Properties
Seismic Hazard Assessment	Pavement Analysis
