Groundwater Hydrology Projects
Hydrologic Impact Aggregate Mine
La Plata County, Colorado Western Water & Land performed a hydrologic impact assessment for an aggregate mining company in western Colorado. The assessment was required to support an application for an amendment to an existing mine permit. The study focused on the potential impacts to private well owners as a result of dewatering operations at the mine. The evaluation was first completed by defining the local geology and hydrogeology using published geologic maps, well information data obtained from Division of Water Resources (DWR’s) well construction reports, and previous hydrologic and subsurface studies completed for the mine.

Groundwater Source Assessment
Sinbad Valley, Mesa and Montrose Counties, Colorado Western Water & Land performed a groundwater source assessment to investigate the tributary status of groundwater flowing from two horizontal wells constructed within a ridge above Sinbad Valley in Mesa and Montrose Counties, Colorado. The assessment was conducted in response to opposition raised in a water rights diligence case for which Western Water & Land was providing technical support. Read more... |
Hydrologic Impact Assessment: Municipal Spring Protection
Garfield County, Colorado Western Water & Land was retained by a natural gas exploration and production company to conduct a source assessment and baseline characterization of a municipal spring located downgradient of a proposed drilling operation. The study is currently underway and is being conducted to support an application for a watershed permit as required by the town. Read more... |
Hydrologic Characterization & Monitoring: Oil Shale Research, Development, and Demonstration Project
Rio Blanco County, Colorado Western Water & Land provides ongoing hydrologic services to one of the leading oil shale research organizations conducting research, development, and demonstration (RD&D) operations in the Piceance Creek Basin in northwestern Colorado. Read more... |
Mine Hydrology: Former Oil Shale Mine
Garfield County, Colorado Western Water & Land is conducting closure activities for a former oil shale mine in western Colorado. As part of closure operations, Western Water & Land conducted a comprehensive underground hydrologic reconnaissance and groundwater sampling program from underground wells. Read more... |
Hydrologic Characterization: Oil Shale Research, Development, and Demonstration Project
Rio Blanco County, Colorado Western Water & Land was the hydrologic consultant to a large oil and gas company for its former oil shale research, development, and demonstration (RD&D) project in northwestern Colorado. Our firm was responsible for complete characterization of the hydrostratigraphy at the research site. The work included preparation of hydrologic sections for the Colorado Division of Reclamation, Mining, and Safety Notice of Intent permit, including conceptual design of groundwater monitoring wells and surface-water baseline sampling programs.

Mine Hydrology: Coal Mine
Northern Arizona Western Water & Land provides ongoing hydrologic services to a large coal mine operating in northern Arizona. Our services have included assessments of water quality of mine water drainage and hydrologic impact of refuse disposal. Assessment of refuse disposal impacts involved delineating the optimum refuse disposal area at the mine and investigating the potential hydrologic impact of the coal-wash refuse material.

Mine Hydrology: Uranium Mine
Mesa County, Colorado Western Water & Land was retained by a uranium mining company to perform a mine hydrology assessment for a uranium mine that the company is reopening in western Colorado. The project involved conducting a field investigation and interpreting surface and underground hydrologic data collected at the mine. The surface work included field mapping of hydrogeologic features and sampling and analysis of key water features. Read more... |
Numerical Groundwater Modeling
Tuba City, Arizona Western Water & Land developed and constructed a numerical groundwater model for over 65 square miles of terrain near Tuba City, Arizona. The work was conducted for MACTEC-ERS, the prime contractor for the U.S. Department of Energy Grand Junction Projects Office. The project involved the development of a local-scale model (Phase II) from a previously completed site-scale model (Phase I). Read more... |
