Groundwater Modeler / Hydrogeologist

Brown and Caldwell has an exciting opportunity for a Sr Staff Groundwater Modeler 6-10 years’ experience to join our Private Sector Enterprise. The position focuses on the development and application of digital solutions related to quantitative hydrogeology with specific experience in performing and directing groundwater flow and contaminant transport studies. The successful candidate will be able to perform complex groundwater flow and transport modelling assignments under the direction of our nationally recognized, senior technical staff working on a variety of exciting environmental remediation, permitting, and water resources projects located throughout the United States. BC is a leader in the application of digital solutions for groundwater water supply and remediation challenges and we are looking for someone who can focus on building robust, repeatable, and scalable solutions for building and running complex groundwater models. The ability and desire to use and develop program code to incorporate computer software applications as part of the solutions is a desirable skill for this role. A basic understanding of handling incomplete hydrologic data sets and evaluating impacts of poorly understood parameters on model performance is a primary goal for this position. Target areas for the application of numerical modeling as decision support tools include: Mine Permitting and Reclamation, Site and Basin-Scale Industrial Remediation; Groundwater Recharge, Storage, and Recovery; Source Water and Aquifer Hydrologic Characterization; and, Water Resources Management and Planning.

This role has the potential to work virtually and can be filled near any BC office, with a preference of Denver, Boise, Phoenix, Boston, Houston, Philadelphia, Atlanta, Portland, Seattle, Reno, Carson City, or Sacramento.

Detailed Description:

• Serve as a technical resource within the BC Groundwater Modeling practice.
• Work may include the reduction of field data, construction of boring logs and geologic cross sections, development of geospatial models of geologic and/hydrogeologic features, analyses of pumping test data, preparation of model input data files, groundwater flow and contaminant fate and transport modeling, preparation of maps using GIS tools, and report preparation.
• Work closely with senior hydrogeology/modelling staff throughout the BC organization
• Participate in development of digital solutions for coupling hydrologic models from integrated domains (e.g. surface water and groundwater).
• Participate in development of model testing protocol designed to evaluate and quantify inherent model uncertainty and therefore increase value of model results.
• Support development of conceptual and numerical groundwater flow and transport models for a variety of projects.
• Perform technical report writing and provide support for presentations to clients, regulators, and other stakeholders.
• Execute diverse quantitative assignments for BC clients in a manner that exceeds client expectations related to work product, deadlines and budgets.
• Manage tasks and assignments to meet critical deadlines and budgets.
• Communicate findings to senior staff and make recommendations as appropriate.
• Draft technical memoranda, reports, and design documents
• Work independently and with multi-disciplined teams to meet project objectives.
• Participate in the development of business opportunities with new and existing clients.

Desired Skills and Experience:

• Master’s Degree in hydrogeology or a hydrology related field including formal training in quantitative hydrogeology and numerical modeling is required.
• 6-10 years’ experience in application of quantitative techniques, including groundwater flow and chemical transport modeling, and hydrologic data organization and analysis.
• Experience supporting groundwater modeling projects that may include, but are not limited to, legacy mine remediation and mine permitting, regional water resources evaluations, and site contaminant fate and transport studies.
• Strong quantitative and computer skills, including a familiarity with hydrogeologic analysis and related software such as the various current versions of MODFLOW, MODFLOW-based pre-/post-processing software (i.e., Groundwater Vistas, Flex, GMS) is required.
• Experience with MT3DMS/MT3D-USGS and or/ MODFLOW6 – GWT is required.
• Experience with aquifer test analysis software (e.g., AQTESOLV, AquiferWin32) is required.
• Experience with geographic information systems (GIS), specifically ArcGIS is required.
• Computer programming skills using Fortran, Python, R, Visual Basic for Applications (VBA), or other programming language is required.
• Experience with geospatial modeling tools such as Leapfrog, EVS or EarthVision is desirable.
• Ability to work and collaborate effectively in a virtual environment with other BC offices and staff.
• Experience with databases including MS Access.
• Experience with parameter estimation and uncertainty analysis, especially use of PEST and PEST ++ is preferred.
• 40-Hour HAZWOPER certification and MSHA Part 48 training a plus.
• Highly organized, reliable, and able to work well with others.
