Thomas J Mack

Biography

Tom Mack has been a hydrologist with the USGS since 1983. He has conducted numerous hydrologic investigations from site-specific contaminant studies to regional-scale resource assessments in the Northeastern U.S., Afghanistan, Africa, Emirates, and Madagascar. He specializes in regional ground-water resource assessments in valley-fill and fractured bedrock settings. Other areas of expertise include: use of remotely-sensed data in regional water-availability investigations, analysis of GIS data for use in regional water-resource evaluation, surface and borehole geophysical techniques, various drilling techniques, and use of groundwater flow models for regional water availability investigations.
