What are the typical responsibilities and collaboration opportunities for an assistant hydrogeologist within a project team?

As an Assistant Hydrogeologist, you will often support senior hydrogeologists and environmental scientists by conducting fieldwork such as groundwater sampling, well installation, and data collection. Your daily tasks may also include analyzing hydrogeological data, preparing reports, and using modeling software under supervision. Collaboration is key in this role, as you’ll work closely with engineers, geologists, and regulatory agencies to ensure projects meet environmental and safety standards. This environment offers excellent learning opportunities and helps you build a strong foundation for advancing to more senior positions.

What is the difference between Assistant Hydrogeologist vs Hydrogeologist?

AspectAssistant HydrogeologistHydrogeologist
Required CredentialsBachelor's degree in geology, hydrogeology, or related field; some certificationsBachelor's or master's degree; professional licensure or certification often preferred
Work EnvironmentFieldwork, data collection, assisting senior staffFieldwork, data analysis, project management, client interaction
Employer & Industry UsageEntry-level roles in environmental consulting, government agencies, water resource companiesMid-level to senior roles in similar sectors, often with more project responsibility

The main difference between an Assistant Hydrogeologist and a Hydrogeologist lies in experience and responsibilities. An Assistant Hydrogeologist typically supports senior staff with data collection and fieldwork, while a Hydrogeologist takes on more independent analysis, project management, and client interaction. Both roles require similar educational backgrounds, but the Hydrogeologist usually has more experience and possibly licensure, enabling greater responsibility in projects.

What is an assistant hydrogeologist?

Assistant Hydrogeologists are entry-level professionals who support senior hydrogeologists in studying the distribution, movement, and quality of groundwater. They assist with fieldwork, data collection, analysis, and report preparation related to water resources and environmental projects. Their work is essential for understanding groundwater systems, managing water supplies, and addressing environmental concerns such as contamination or drought. Assistant Hydrogeologists often work for consulting firms, government agencies, or environmental organizations, and their role provides valuable hands-on experience in the field of hydrogeology.

What are the key skills and qualifications needed to thrive as an assistant hydrogeologist, and why are they important?

To thrive as an Assistant Hydrogeologist, you need a solid background in geology or environmental science, typically with a relevant bachelor's degree, and foundational knowledge of hydrogeological principles. Familiarity with groundwater modeling software (e.g., MODFLOW), GIS tools, and data collection instruments is often required. Strong analytical thinking, attention to detail, and effective communication are vital soft skills for fieldwork and reporting findings. These competencies ensure accurate data analysis, effective project support, and compliance with environmental regulations in water resource management.

Job description

Title: Groundwater Modeler/Hydrogeologist
Department: MBMG - Ground Water Investigation Program
Job Type: Professional Full-Time
Montana Technological University provides a comprehensive benefits package for all eligible positions that includes health, dental and vision insurance, mandatory retirement plan with employer contribution, partial tuition waiver, and a wellness program.
Applications received by 9/8/2026 will be guaranteed full review and consideration. Applications received after that date may be considered until an adequate applicant pool has been established.
Duties:
The Butte office of the Montana Bureau of Mines and Geology (Montana's state geologic survey) seeks a highly motivated quantitative hydrogeologist trained in groundwater modeling techniques to develop and apply groundwater models for water resources evaluation. The MBMG's Ground Water Investigation Program studies local- to regional-scale hydrogeologic systems, with projects that encompass groundwater/surface-water interactions and groundwater quantity and quality. A primary focus of the position will be to use groundwater modeling, scripting/programming, parameter estimation, GIS, and visualization software to develop and apply groundwater flow models for water resources evaluations. Responsibilities also include aiding in project design, collecting and interpreting geologic and hydrogeologic data, and writing reports.
The successful candidate will join a vibrant group of geoscientists committed to providing high-quality data and interpretations to support the orderly and responsible development of Montana's natural resources. The MBMG is a department of the Montana Technological University, but this is a non-tenurable, non-teaching position.
Required Qualifications:
  • Minimum requirements for hiring levels: Assistant Hydrogeologist: Master's Degree and 3 years relevant experience or Doctoral Degree, in geology, hydrology, hydrogeology, or closely related field. Associate Hydrogeologist: Master's Degree and 8 years relevant experience in geology, hydrology, hydrogeology, or closely related field or Doctoral Degree and 5 years' experience.
  • Course work in geology, hydrogeology, and numerical groundwater flow modeling listed in your resume.
  • Applicable hydrogeologic/geologic field experience.
  • Demonstrated experience developing conceptual groundwater models, including water-budget estimates.
  • Demonstrated experience implementing conceptual models as numerical models using modern versions of MODFLOW (e.g., MODFLOW-NWT, MODFLOW-USG, or MODFLOW 6) and associated pre- and post-processing software.
  • Strong technical writing and communications skills demonstrated through a record of reports and presentations listed in your résumé.
  • Proficiency with common word-processing and spreadsheet software (e.g., Microsoft Office).
  • A valid Montana driver's license (or ability to acquire one).
  • Applicants must be legally authorized to work in the United States at the time of application. The employer is not able to sponsor employment visas for this position.
Preferred Qualifications:
  • Groundwater project experience from design and data collection through interpretation and publication.
  • GIS skills, including project creation, geospatial data analysis, and interpretation.
  • Experience with developing code for efficient pre- and post-processing of model inputs and outputs, particularly using Python, R, or similar languages; familiarity with Fortran is also desirable.
  • Experience with techniques for model calibration through parameter estimation and uncertainty analysis of model predictions, such as through PEST.
  • Experience using MODFLOW models with unstructured grids.
  • Familiarity with traditional aquifer test analysis methods and simulation of aquifer tests in numerical models.
  • Familiarity with variably saturated groundwater flow modeling (e.g., HYDRUS) or coupled groundwater-surface water flow (e.g., GSFLOW).
  • Familiarity with surface water (e.g., RiverWare), watershed (e.g., PRMS or HSPF), hydraulic (HEC-RAS), and geochemical (e.g., PHREEQC, Geochemist's Workbench, or MINTEQ) modeling.

For full consideration application materials must be complete.
Please include:
  • Cover letter addressing qualifications,
  • Resume
  • Contact information for 3 professional references.

Application Requirements
For full consideration application materials must be complete.
Any offer of employment is contingent upon a satisfactory criminal background check.
