Andrew Manning is a Research Geologist with the Geology, Geophysics, and Geochemistry Science Center.
Andrew Manning has been a Research Geologist with the U.S. Geological Survey since 2002. His research is largely focused on using noble gases and other environmental tracers to study mountain groundwater flow systems. His recent work focuses more specifically on the transport of metals in groundwater in mineralized mountain areas, and has expanded to include studying the source and migration of ore fluids responsible for the formation of mineral deposits.

Screening Techniques for Legacy Mine Land (LML) Sites Using Data Mining and Site-specific Studies in the Western U.S.
The main goal of this project is to provide a science-based approach for screening legacy mine land (LML) sites for remediation and identifying watersheds where relatively low-cost restoration efforts may yield substantial improvements to stream water quality. We are combing analysis of multiple existing regional data coverages with focused field studies to develop a protocol that land managers...
Metal Transport in Mineralized Mountain Watersheds
The central objective of this project is to develop a greater understanding of deep bedrock groundwater circulation and its contribution to surface water metal loads in mineralized mountain blocks composed of sedimentary rocks. This work is being performed in cooperation with Lawrence Berkeley National Laboratory as part of a broader research program aimed at understanding processes controlling...
Geochemical Signatures of Covered Mineral Deposits in the Northern Midcontinent
We are evaluating the potential of geochemical prospecting techniques that have shown promise in other covered terranes for mineral exploration in the northern midcontinent of the U.S. Novel components will be added to these methods with the objective of method advancement and improving our understanding of processes controlling the transmission of unique geochemical signatures from buried mineral...
Potential Impacts of Prospective Climate Change on Groundwater Recharge in the Western United States
Groundwater withdrawals in the western US are a critical component of the water resources strategy for the region. Climate change already may be substantially altering recharge into groundwater systems; however, the quantity and direction (increase or decrease) of changes are relatively unknown as most climate change assessments have focused on surface water systems. We propose to conduct a broad
