McLane Environmental offers a wide range of geologic services including logging, mapping, geophysical surveys, research and evaluation of historical geologic information for a site, and preparation of cross sections and other depictions of geologic information beneath a site or property. These analyses can be used by an engineering project team, as part of a resource evaluation or site suitability study, or for submittal to a regulatory agency to meet permitting or compliance requirements.

The array of geologic services offered by McLane Environmental includes:

• Borehole Logging
• Monitoring Well Design
• Geophysical Survey and Analysis
• Geologic & Hydrostratigraphic Mapping
• Geologic Cross Sections
• 3-D Geologic Data Visualization
• Interpretation of Geologic Environments
• Geologic Reports

Our geophysicists have experience with various geophysical survey methods including seismic refraction and reflection, electromagnetic, DC resistivity, gravity, magnetic, and ground penetrating radar. These methods are applied to map clay layers, buried streambeds, depth to groundwater, depth to bedrock, saltwater interface elevation, disturbed soils, UST or buried drum locations, and unexploded ordinance (UXO).

Representative Experience

McLane Environmental geologists have provided a wide range of advisory, oversight, and consulting services including:

• Performed geologic interpretation and prepared technical geologic reports to support site conceptual models, groundwater models, and related analyses for water supply, site remediation, and litigation support projects.
• Planned and oversaw the location, design and construction of monitoring wells for numerous projects including remedial site investigations and water supply projects.
• Provided geologic services including borehole logging using reverse mud rotary, air rotary, auger, and roto-sonic techniques for the installation of monitoring wells at a Superfund site in California.
• Researched, collected, and interpreted existing lithologic log and monitoring well data for the development of geologic conceptual models, cross sections, and 3-D diagrams and for the construction of detailed groundwater flow and transport models in Ohio, California, Idaho, and Massachusetts.
• Evaluated southwestern alluvial basin lithofacies data to identify groundwater flow pathways and assess contaminant contribution from two chlorinated solvent sites located in the vicinity of a public water supply well field.
• Performed groundwater flow analyses for a karst limestone aquifer to identify likely sources of chlorinated solvent contamination observed at numerous wells and groundwater discharge locations in the vicinity of a former manufacturing facility.
• Analyzed lithologic log and monitoring well data in conjunction with geophysical surveys (seismic, radar, and EM) to develop a conceptual model and numerical model used to simulate a tracer test at a site in Idaho.
• Conducted seismic surveys for geologic mapping of several hydrogeologic units in Idaho to determine water bearing units.
• Conducted gravity survey to verify the location of the Golden Fault in Golden Colorado.
• Applied geophysical techniques for unexploded ordinance (UXO) detection at Department of Defense installations in South Dakota and New York State as part of land restoration and reuse projects.

Geology is a key component of many environmental and engineering projects. McLane’s highly trained geoscientists apply state-of-the-art techniques to ensure that all geologic data for our subsurface projects are properly collected and accurately interpreted.
