John Sciacca , PG

John Sciacca is a California Professional Geologist with over 35 years of professional experience. He holds an M.S. in Geology from the University of California, Davis and is a principal hydrogeologist for AECOM in northern Nevada. John previously served as the Director of the Nevada Water Science Center for the U.S. Geological Survey. He currently provides technical consulting and oversight for hydrogeologic investigation and remediation projects; and, data collection for water resources and environmental applications. Throughout his career, Mr. Sciacca has used and interpreted direct push technology (DPT) for project applications. Some examples include: hydrostratigraphic analysis of cone penetrometer test (CPT) logs to support monitoring network design and model refinement; use of DPT to define dissolved phase and non-aqueous phase liquid (NAPL) plumes; and, DPT to support design of in-situ chemical oxidation and electrical resistance heating remedial actions. Mr. Sciacca’s experience with borehole geophysical logging began 34 years ago. Throughout his professional career John has successfully designed borehole geophysical logging programs and applied log interpretation to design and complete production and injection wells, conduct hydrostratigraphic analysis in depositional basins, map aquifer units, and evaluate aquifer and formation parameters. John has provided consulting services for the workover/rehabilitation and abandonment of municipal and private domestic water production wells. He has also conducted workshops on geophysical log quality control and presented papers on log quality and log interpretation for hydrogeologic applications.
