🎯 Role Definition

A Hydro Geologist is a specialized earth scientist focused on the study of groundwater. You are the expert on how water moves through the earth's subsurface, its quality, and its interaction with the surrounding rock and soil. This role is crucial for a wide range of industries, including environmental consulting, water resource management, mining, and civil engineering. As a Hydro Geologist, you'll be responsible for assessing water availability, investigating contamination, designing remediation systems, and ensuring that projects comply with environmental regulations. You are part scientist, part engineer, and part environmental steward, blending field work with sophisticated data analysis and modeling to solve complex water-related challenges.

Core Responsibilities

Primary Functions

  • Design, implement, and manage comprehensive hydrogeological field investigations to characterize groundwater conditions, including flow direction, gradient, and quality.
  • Develop and execute groundwater monitoring plans and sampling programs to assess long-term trends and ensure regulatory compliance for industrial sites, landfills, and remediation projects.
  • Plan, oversee, and interpret aquifer performance tests, such as pumping tests, slug tests, and packer tests, to determine aquifer properties like transmissivity, hydraulic conductivity, and storativity.
  • Construct and refine Conceptual Site Models (CSMs) that integrate geological, hydrological, and chemical data to create a holistic understanding of groundwater systems and contaminant behavior.
  • Develop, calibrate, and run numerical groundwater flow and contaminant transport models using industry-standard software (e.g., MODFLOW, FEFLOW) to predict future conditions and evaluate various management scenarios.
  • Oversee drilling operations for the installation of monitoring wells, piezometers, and water supply wells, including soil logging, well design, and development.
  • Author and peer-review in-depth technical reports, hydrogeological assessments, and sections of Environmental Impact Assessments (EIAs) for submission to clients and regulatory agencies.
  • Evaluate the potential impacts of proposed projects, such as mining operations, infrastructure development, or land use changes, on local and regional groundwater resources.
  • Conduct sophisticated contaminant fate and transport analyses to delineate plume boundaries, predict migration pathways, and assess risks to human health and the environment.
  • Perform detailed water balance and resource evaluation studies to support water supply planning, mine dewatering designs, and managed aquifer recharge (MAR) initiatives.
  • Characterize and quantify groundwater-surface water interactions to understand baseflow contributions to rivers and wetlands and assess the ecological implications of changing water levels.
  • Develop and evaluate remedial action plans for contaminated groundwater sites, ranging from monitored natural attenuation to active treatment technologies like pump-and-treat or in-situ chemical oxidation.
  • Serve as a key technical liaison, effectively communicating complex hydrogeological findings and their implications to a diverse audience of clients, project managers, regulators, and legal counsel.
  • Utilize Geographic Information Systems (GIS) software to manage, analyze, and visualize spatial hydrogeological data, creating compelling maps and figures for reports and presentations.
  • Ensure all project activities adhere strictly to health and safety protocols as well as local, state, and federal environmental regulations (e.g., CERCLA, RCRA).
  • Provide mentorship, technical guidance, and field training to junior-level geologists, scientists, and technicians, fostering their professional development.
  • Manage project scope, budgets, and schedules for hydrogeology-related tasks, ensuring projects are completed on time and within budget while meeting technical objectives.

Secondary Functions

  • Support ad-hoc data requests and conduct exploratory data analysis to uncover new insights from historical or newly collected hydrogeological datasets.
  • Contribute to the development of internal best practices, technical standards, and standard operating procedures (SOPs) for hydrogeological investigations.
  • Collaborate with cross-functional teams, including geotechnical engineers, environmental scientists, and civil engineers, to integrate hydrogeological considerations into broader project designs.
  • Participate in project planning meetings, providing expert technical input and estimating resource requirements and timelines for hydrogeological tasks.
  • Assist in business development efforts by contributing technical expertise to proposals, preparing cost estimates, and representing the company's hydrogeological capabilities to potential clients.
