Hydrogeology

Hydrogeology, the study of groundwater, is one of the most important areas of environmental science.  Groundwater commonly controls the baseflow of river systems and determines the presence and extent of wetland habitats.  Its interaction with soil and rock can greatly affect geotechnical properties and it is a common pathway (and receptor) for pollutants.  Most importantly, groundwater makes a huge contribution (often the only contribution) to water supplies.

What is the benefit?

Hydrogeological investigations are generally targeted to obtain specific information.  Small, site-based studies may provide, for example, site baseline groundwater quality data to determine compliance with regulatory criteria.  The nature and extent of contaminant plumes may be identified through a combination of site works and computer modelling, which may facilitate the definition of remedial measures.  Drilling and subsequent pumping tests can be undertaken to define potential abstraction rates for the sustainable use of local groundwater resources.  Whatever the requirement, appropriately scoped hydrogeological studies add value to many projects in which groundwater plays a part.

Why CRA?

CRA has decades of experience in hydrogeology.  Our hydrogeologists have worked on some of the most challenging groundwater pollution studies and we are recognised globally as a leader in groundwater remediation.  We work with our clients and subcontractors fostering a one-team approach whereby all team members work towards the project objective.

CRA’s groundwater experience includes: compliance monitoring, contaminant plume delineation, physical and chemical modelling, design and implementation of insitu and exsitu remediation measures, and water resource evaluation.  In addition, our staff are commonly asked to provide university lectures on groundwater issues.
