Philip Gardner
Philip Gardner is a Hydrologist and the Groundwater Specialist for the Nevada Water Science Center.
Phil has worked as a hydrologist with the US Geological Survey since 2001 and is currently the Groundwater Specialist at the Nevada Water Science Center in Carson City, NV. Much of his work has focused on the development of conceptual and numerical models of hydrologic systems and groundwater-surface water interaction throughout the eastern Great Basin and Colorado Plateau.

Hydrogeologic and geochemical characterization of groundwater resources in Rush Valley, Tooele County, Utah
The water resources of Rush Valley were assessed during 2008–2010 with an emphasis on refining the understanding of the groundwater-flow system and updating the groundwater budget. Surface-water resources within Rush Valley are limited and are generally used for agriculture. Groundwater is the principal water source for most other uses including supplementing irrigation. Most groundwater withdrawaAuthorsPhilip M. Gardner, Stefan KirbyEvaluation of the effects of precipitation on ground-water levels from wells in selected alluvial aquifers in Utah and Arizona, 1936-2005
Increased withdrawals from alluvial aquifers of the southwestern United States during the last half-century have intensified the effects of drought on ground-water levels in valleys where withdrawal for irrigation is greatest. Furthermore, during wet periods, reduced withdrawals coupled with increased natural recharge cause rising ground-water levels. In order to manage water resources more effectAuthorsPhilip M. Gardner, Victor M. HeilweilThree-dimensional numerical model of ground-water flow in northern Utah Valley, Utah County, Utah
A three-dimensional, finite-difference, numerical model was developed to simulate ground-water flow in northern Utah Valley, Utah. The model includes expanded areal boundaries as compared to a previous ground-water flow model of the valley and incorporates more than 20 years of additional hydrologic data. The model boundary was generally expanded to include the bedrock in the surrounding mountainAuthorsPhilip M. GardnerHydrology of Northern Utah Valley, Utah County, Utah, 1975-2005
The ground-water resources of northern Utah Valley, Utah, were assessed during 2003-05 to describe and quantify components of the hydrologic system, determine a hydrologic budget for the basin-fill aquifer, and evaluate changes to the system relative to previous studies. Northern Utah Valley is a horst and graben structure with ground water occurring in both the mountain-block uplands surroundingAuthorsJay R. Cederberg, Philip M. Gardner, Susan A. ThirosInfiltration and recharge at Sand Hollow, an upland bedrock basin in southwestern Utah: Chapter I in Ground-water recharge in the arid and semiarid southwestern United States (Professional Paper 1703)
Permeable bedrock aquifers in arid regions of the southwestern United States are being used increasingly as a source of water for rapidly growing populations, yet in many areas little is known about recharge processes and amounts available for sustainable development. Environmental tracers were used in this study to investigate infiltration and recharge to the Navajo Sandstone at Sand Hollow in thAuthorsVictor M. Heilweil, D. Kip Solomon, Philip M. GardnerBorehole environmental tracers for evaluating net infiltration and recharge through desert bedrock
Permeable bedrock aquifers in arid regions are being increasingly developed as water supplies, yet little is generally known about recharge processes and spatial and temporal variability. Environmental tracers from boreholes were used in this study to investigate net infiltration and recharge to the fractured Navajo Sandstone aquifer.

GardnerPre- and post-reservoir ground-water conditions and assessment of artificial recharge at Sand Hollow, Washington County, Utah, 1995-2005
Sand Hollow, Utah, is the site of a surface-water reservoir completed in March 2002, which is being operated by the Washington County Water Conservancy District primarily as an aquifer storage and recovery project. The reservoir is an off-channel facility receiving water from the Virgin River, diverted near the town of Virgin, Utah. It is being operated conjunctively, providing both surface-waterAuthorsVictor M. Heilweil, David D. Susong, Philip M. Gardner, Dennis E. WattNon-USGS Publications**
