ENVIRONMENTAL GEOPHYSICS

Earth Systems can design and implement a detailed geophysical program, process and interpret the data and provide professional reports.

Geophysical methods that Earth Systems can utilise include ground magnetics, ground penetrating radar (GPR), electromagnetic techniques, resistivity, self potential and seismic methods.

Some of the key applications in this sector include:
Ground water levels and water leakage determinations
Subsurface characterisation to assist geotechnical programs
Polluted ground water plume and contaminated site mapping
Buried artefacts location identification (such as old fuel drums, storage tanks, metal waste etc.)
Pipeline, conduit, buried infrastructure and wiring mapping
Cavity detection
Radioactive waste location identification
Hazardous waste disposal site assessment
Assistance in acid drainage risk assessment and management at mines

	Geophysical methods will often provide a useful and inexpensive adjunct to other methods in assessing environmental issues. They may not always define the precise dimensions of a target object but are part of ensuring that the larger program is effective, quick and cost efficient.

Some of the benefits of utilising geophysics in environmental applications are: Accurate mapping of solid waste, contaminant plumes or existing ground problems in two or three dimensions Reduced bore hole drilling and sampling requirements (geophysics will define the optimum areas for sampling) Reduced requirements for fixed monitoring stations Non-invasive geophysical methods lead to decreased post investigation site clean up costs Lowering costs for environmental investigations
