Collects basic surface water field data by making tests and measurements such as stage-discharge, dissolved oxygen, sediment load, and specific conductance to determine watershed characteristics and water quality, and establish relationships for forecasting availability of water supplies.

Collects basic groundwater field data by making tests and measurements such as pH, alkalinity, specific conductance, groundwater levels, and pump tests data to determine aquifer properties and quality of water contained therein.

Conducts routine investigations and solves simple hydrologic problems.

Performs well inventories, including on-site measurements of hydrologic parameters.

Installs, monitors, and maintains continuous recording and related equipment.

Analyzes, interprets, adjusts, and correlates geophysical, hydrologic, geologic, and related data.

Prepares, enters, and retrieves related computerized data.
