This is advanced professional geo-hydrological work with some supervisory responsibility in the conservation and management of water resources in an environmental resources management program.

Employees in this class are responsible for supervision of technical and professional employees engaged in the conduct of qualitative and quantitative hydrologic investigations and analyses. Emphasis of the work is on supervision of geologic, hydrologic and other technical studies, quantitative determination of interrelations between water quality characteristics and environmental factors, scheduling of laboratory procedures and interpretation of findings. Supervision is exercised through assignment of work, control of field and laboratory procedures and responsibility for reporting field and laboratory findings. General supervision is received from a professional superior who reviews work through conferences, written reports and occasional observation of field and laboratory activities.

ILLUSTRATIVE TASKS

Supervises the chemical and physical analyses of water samples to determine water quality characteristics including source of nutrients and presence of pollutants; prepares and reviews detailed technical reports of field surveys and laboratory findings.

Supervises and participates in comprehensive studies 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 research, experiments and studies concerning the location of freshwater/saltwater interface, effects of canals on groundwater systems, development of aquatic communities, effects of stormwater runoff on water quality, attenuation capabilities of aquifiers, preparation of surface and groundwater monitoring networks and related geo-hydrological matters.

Interprets findings of qualitative and quantitative hydrologic studies to determine the long range effects of potential and existing water contamination.

Assists with the implementation of new field and laboratory procedures; devises quality control techniques and calculates standard deviations on sampling and testing procedures.

Compiles various types of water resources data concerning water quality and water levels; requisitions materials and equipment.

Performs related work as required.
