Characterizing the subsurface groundwater and soil conditions is an important component in environmental site assessment and remediation projects. We have utilized geophysical methods in environmental projects to help map site hydrogeology, preferential contaminant pathways, extent of contamination, and the location of buried debris and objects of concern. Collier’s suite of geophysical solutions provides environmental and engineering companies with rapid, cost-effective, and detailed near-surface information. When incorporated in the early stages of your site characterization project, geophysical investigations can significantly increase your site understanding and help maximize the overall site monitoring and or remediation approach.
