This is professional geo-hydrological work in the conservation and management of water resources in an environmental resource management program.

Employees in this class are responsible for the conduct of hydrologic investigations and participation in technical studies related to water resources management. Duties include the qualitative and quantitative analysis of water samples, identification of pollutants constituting present or potential hazards to water resources and preparation of analytical reports of field surveys and laboratory findings. Incumbents apply advanced knowledge of scientific and analytical principles and exercise some independent judgment in completing assigned tasks. Supervision is received from a professional superior who assigns work, reviews field and laboratory data and assists with unusual or difficult analyses.

ILLUSTRATIVE TASKS

Performs chemical and physical analyses of water samples using qualitative and quantitative procedures; determines water quality characteristics including source of nutrients and presence of pollutants; prepares laboratory reports of results and findings.

Perticipates in qualitative and quantitative investigations in specialized fields such as mathematical modeling, geophysics, water quality, marine geology and sedimentology to identify present or potential effluents, pollutants and toxins harmful to water resources.

Conducts field and laboratory analyses to determine geohydrologic factors related to land and subsurface disposal and storage of liquid and solid waste; studies animal and plant life as they affect and are affected by sediment and dissolved materials in natural water.

Participates in studies concerning chemical and physical interactions between the surface and groundwater, the relationship between water quality characteristics and environmental factors, and the effects of natural and induced phenomena on groundwater systems.

Prepares chemical reagents for field studies and laboratory analyses, maintains inventory of laboratory equipment and supplies; maintains sample logs and compiles statistical data.

Assists in the preparation of technical reports concerning comprehensive evaluation studies and field surveys.

Performs related work as required.
