Groundwater Resource Services

CRA provides a complete range of groundwater resource services. Our staff of geologists, hydrogeologists and geotechnical engineers are highly experienced in the drilling and installation of wells, and in field and laboratory testing necessary to determine subsurface conditions, aquifer properties, groundwater flow characteristics, groundwater quality, and fate/transport of contaminants. CRA utilises visualisation techniques to aid in the understanding and presentation of hydrogeologic information. Our groundwater services include:
