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.

Potential climate change effects on water tables and pyrite oxidation in headwater catchments in Colorado
A water, energy, and biogeochemical model (WEBMOD) was constructed to simulate hydrology and pyrite oxidation for the period October 1992 through September 1997. The hydrologic model simulates processes in Loch Vale, a 6.6-km² granitic watershed that drains the east side of the Continental Divide. Parameters describing pyrite oxidation were...
Medley, C. Nicholas; Patterson, Glenn; Parker, Melanie J.; Webb, Richard M.; Mast, Alisa; Manning, Andrew H.; Clow, David W.; Campbell, Donald H. Using dissolved gases to observe the evolution of groundwater age in a mountain watershed over a period of thirteen years
Baseflows in snowmelt-dominated mountain streams are critical for sustaining ecosystems and water resources during periods of greatest demand. Future climate predictions for mountainous areas throughout much of the western U.S. include increasing temperatures, declining snowpacks, and earlier snowmelt periods. The degree to and rate at which these...
Manning, Andrew H. Mapping permeability over the surface of the Earth
Permeability, the ease of fluid flow through porous rocks and soils, is a fundamental but often poorly quantified component in the analysis of regional‐scale water fluxes. Permeability is difficult to quantify because it varies over more than 13 orders of magnitude and is heterogeneous and dependent on flow direction. Indeed, at the regional scale...

Spring runoff water-chemistry data from the Standard Mine and Elk Creek, Gunnison County, Colorado, 2010
Water samples were collected approximately every two weeks during the spring of 2010 from the Level 1 portal of the Standard Mine and from two locations on Elk Creek. The objective of the sampling was to: (1) better define the expected range and timing of variations in pH and metal concentrations in Level 1 discharge and Elk Creek during spring...
Manning, Andrew H.; Verplanck, Philip L.; Mast, Alisa; Marsik, Joseph; McCleskey, R. Blaine Classifying the water table at regional to continental scales
Water tables at regional to continental scales can be classified into two distinct types: recharge-controlled water tables that are largely disconnected from topography and topography-controlled water tables that are closely tied to topography. We use geomatic synthesis of hydrologic, geologic and topographic data sets to quantify and map water-...

Noble gas recharge temperatures (NGTs) and radiocarbon ages were determined for 43 groundwater samples collected in the eastern Española Basin, New Mexico (USA), to identify mountain-block recharge in waters <10 thousand years (ka) old and to evaluate possible changes in mountain-block recharge over the past ∼35 ka. For Holocene samples...

Characterization of Geologic Structures and Host Rock Properties Relevant to the Hydrogeology of the Standard Mine in Elk Basin, Gunnison County, Colorado
The Standard Mine Superfund Site is a source of mine drainage and associated heavy metal contamination of surface and groundwaters. The site contains Tertiary polymetallic quartz veins and fault zones that host precious and base metal sulfide mineralization common in Colorado. To assist the U.S. Environmental Protection Agency in its effort to...

Geophysical Characterization of Subsurface Properties Relevant to the Hydrology of the Standard Mine in Elk Basin, Colorado
Geophysical data were collected at the Standard Mine in Elk Basin near Crested Butte, Colorado, to help improve the U.S. Environmental Protection Agency's understanding of the hydrogeologic controls in the basin and how they affect surface and groundwater interactions with nearby mine workings. These data are discussed in the context of geologic...

Geochemistry of standard mine waters, Gunnison County, Colorado, July 2009
In many hard-rock-mining districts water flowing from abandoned mine adits is a primary source of metals to receiving streams. Understanding the generation of adit discharge is an important step in developing remediation plans. In 2006, the U.S. Environmental Protection Agency listed the Standard Mine in the Elk Creek drainage basin near Crested...

Ground-Water Temperature, Noble Gas, and Carbon Isotope Data from the Espanola Basin, New Mexico
Ground-water samples were collected from 56 locations throughout the Espanola Basin and analyzed for general chemistry (major ions and trace elements), carbon isotopes (delta 13C and 14C activity) in dissolved inorganic carbon, noble gases (He, Ne, Ar, Kr, Xe, and 3He/4He ratio), and tritium. Temperature profiles were measured at six locations in...
