Data collection in a groundwater remedial investigation can begin with minimally intrusive techniques, called initial field screening techniques. These techniques are less expensive than the more intrusive techniques such as soil borings, test pits, and well monitoring. In addition, field screening techniques provide information which streamlines data collection and optimizes the use of intrusive techniques. The principal categories of initial field screening techniques include surface and downhole geophysical surveys and onsite chemical screening, such as a soil-gas survey.
