Geological and Hydrologic Technicians

Geological and Hydrologic Technicians are applied science professionals who support geologists, hydrologists, and environmental scientists by collecting, analyzing, and managing earth science and water-related data. They work in the field and laboratory to monitor natural resources, study geological formations, and track water quality and availability. Their work provides the hands-on data that informs decisions about environmental protection, construction, resource management, and hazard mitigation.

This career is well suited for individuals who enjoy outdoor fieldwork, scientific measurement, and applying technical skills to understand Earth systems.

What Do Geological and Hydrologic Technicians Do?

Geological and hydrologic technicians gather data and assist with research related to soil, rock, groundwater, and surface water. Their responsibilities combine field sampling, laboratory testing, and data documentation.

Common responsibilities include:

• Collecting soil, rock, sediment, and water samples
• Measuring stream flow, groundwater levels, and water quality
• Installing and maintaining monitoring equipment
• Conducting laboratory tests on geological or water samples
• Recording, organizing, and validating field data
• Assisting scientists with environmental studies and surveys
• Preparing maps, charts, and technical reports

Types of Geological and Hydrologic Technicians

Technicians may specialize based on the type of data or environment they work with:

• Geological Technicians: Support studies of rocks, minerals, and earth formations.
• Hydrologic Technicians: Focus on surface water, groundwater, and water quality monitoring.
• Environmental Field Technicians: Assist with environmental impact and remediation projects.
• Mining and Resource Technicians: Support exploration and resource assessment efforts.
• Engineering Support Technicians: Collect subsurface and site data for construction projects.
