Andrew H Manning
Biography
B.A. Earth Science, Wesleyan University, Middletown, CT
M.S. Geology, with focus in structural geology, University of Utah, Salt Lake City
Ph.D. Geology, with focus in hydrogeology, University of Utah, Salt Lake City
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.

U.S. Geological Survey research in Handcart Gulch, Colorado—An alpine watershed with natural acid-rock drainage
Handcart Gulch is an alpine watershed along the Continental Divide in the Colorado Rocky Mountain Front Range. It contains an unmined mineral deposit typical of many hydrothermal mineral deposits in the intermountain west, composed primarily of pyrite with trace metals including copper and molybdenum. Springs and the trunk stream have a natural pH...

Hydrogeochemical investigation of the Standard Mine Vicinity, Upper Elk Creek Basin, Colorado
Ground- and surface-water samples were collected in the vicinity of the Standard Mine in west-central Colorado in order to characterize the local ground-water flow system, determine metal concentrations in local ground water, and better understand factors controlling the discharge of metal-rich waters from the mine. The sampling program included a...
Manning, Andrew H.; Verplanck, Philip L.; Mast, Alisa; Wanty, Richard B. Ground- and surface-water chemistry of Handcart Gulch, Park County, Colorado, 2003-2006
As part of a multidisciplinary project to determine the processes that control ground-water chemistry and flow in mineralized alpine environments, ground- and surface-water samples from Handcart Gulch, Colorado were collected for analysis of inorganic solutes and water and dissolved sulfate stable isotopes in selected samples. The primary aim of...

Presentation Showing Results of a Hydrogeochemical Investigation of the Standard Mine Vicinity, Upper Elk Creek Basin, Colorado
PREFACE This Open-File Report consists of a presentation given in Crested Butte, Colorado on December 13, 2007 to the Standard Mine Advisory Group. The presentation was paired with another presentation given by the Colorado Division of Reclamation, Mining, and Safety on the physical features and geology of the Standard Mine. The presentation in...
Manning, Andrew H.; Verplanck, Philip L.; Mast, Alisa; Wanty, Richard B. Regional groundwater flow in mountainous terrain: Three‐dimensional simulations of topographic and hydrogeologic controls
This study uses numerical simulations to define the salient controls on regional groundwater flow in 3‐D mountainous terrain by systematically varying topographic and hydrogeologic variables. Topography for idealized multiple‐basin mountainous terrain is derived from geomatic data and literature values. Water table elevation, controlled by the...
Gleeson, Tom; Manning, Andrew H. Selected water-quality data for the Standard Mine, Gunnison County, Colorado, 2006-2007
Mine drainage and underground water samples were collected for analysis of inorganic solutes as part of a 1-year, hydrogeologic investigation of the Standard Mine and vicinity. The U.S. Environmental Protection Agency has listed the Standard Mine in the Elk Creek drainage near Crested Butte, Colorado, as a Superfund Site because discharge from the...

In San Juan County, Colo., the effects of historical mining continue to contribute metals to ground water and surface water. Previous research by the U.S. Geological Survey identified ground-water discharge as a significant pathway for the loading of metals to surface water in the upper Animas River watershed from both acid-mine drainage and acid-...
Johnson, Raymond H.; Wirt, Laurie; Manning, Andrew H.; Leib, Kenneth J.; Fey, David L.; Yager, Douglas B. Groundwater noble gas, age, and temperature signatures in an Alpine watershed: Valuable tools in conceptual model development
Bedrock groundwater in alpine watersheds is poorly understood, mainly because of a scarcity of wells in alpine settings. Groundwater noble gas, age, and temperature data were collected from springs and wells with depths of 3–342 m in Handcart Gulch, an alpine watershed in Colorado. Temperature profiles indicate active groundwater circulation to a...
Manning, Andrew H.; Caine, Jonathan S. Well construction information, lithologic logs, water level data, and overview of research in Handcart Gulch, Colorado: an alpine watershed affected by metalliferous hydrothermal alteration
Integrated, multidisciplinary studies of the Handcart Gulch alpine watershed provide a unique opportunity to study and characterize the geology and hydrology of an alpine watershed along the Continental Divide. The study area arose out of the donation of four abandoned, deep mineral exploration boreholes to the U.S. Geological Survey for research...
Caine, Jonathan S.; Manning, Andrew H.; Verplanck, Philip L.; Bove, Dana J.; Kahn, Katherine Gurley; Ge, Shemin 3H/3He age data in assessing the susceptibility of wells to contamination
Regulatory agencies are becoming increasingly interested in using young–ground water dating techniques, such as the 3H/3He method, in assessing the susceptibility of public supply wells (PSWs) to contamination. However, recent studies emphasize that ground water samples of mixed age may be the norm, particularly from long-screened PSWs, and...
Manning, Andrew H.; Solomon, D. Kip; Thiros, Susan A. An integrated environmental tracer approach to characterizing groundwater circulation in a mountain block
The subsurface transfer of water from a mountain block to an adjacent basin (mountain block recharge (MBR)) is a commonly invoked mechanism of recharge to intermountain basins. However, MBR estimates are highly uncertain. We present an approach to characterize bulk fluid circulation in a mountain block and thus MBR that utilizes environmental...
Manning, Andrew H.; Solomon, D. Kip Quality and sources of ground water used for public supply in Salt Lake Valley, Salt Lake County, Utah, 2001
Ground water supplies about one-third of the water used by the public in Salt Lake Valley, Utah. The occurrence and distribution of natural and anthropogenic compounds in ground water used for public supply in the valley were evaluated. Water samples were collected from 31 public-supply wells in 2001 and analyzed for major ions, trace elements,...
