Environmental, Hydrogeology and Archaeological

Environmental Geophysics

Assessment of site environmental hazards such as:

• Location and delineation of uncontrolled fill such as buried waste drums - Magnetometer, FDEM and GPR
• Location of remnant subsurface infrastructure - FDEM and GPR
• Location of unexploded ordnance (UXOs) - Magnetometer and FDEM
• Delineation of inorganic contaminant plumes - FDEM and ERI
• Detection of abandoned mine workings including shafts and adits - GPR, FDEM and ERI
• Tree root mapping - GPR
• Delineation of landfill extents, fill base and capping thickness - MASW, GPR, ERI and FDEM

Hydrogeology

Assessment of subsurface hydrogeological conditions including:

• Mapping of geological sequences for groundwater including identification of potential aquifer/aquitard units - ERI, FDEM and TDEM
• Determination of water table depth - ERI
• Targeting geological sequences with high groundwater yields - TDEM and ERI
• Defining fresh / saltwater interface - ERI and TDEM
• Assessment of dryland salinity - FDEM

Archaeological

Assessment of sites of archaeological significance including:

• Buried remnant structures including walls, slabs and footings - GPR, FDEM and Magnetometer
• Unmarked grave site locations at cemeteries, private burial sites, forensics as well as aboriginal sites and interments - GPR
• Marine archaeological sites including wreck location - Marine Magnetometer and Side Scan Sonar.
