CHEMIST I

NATURE OF WORK

This is scientific work in performing laboratory analysis for air and water pollution control or overseeing activities of a treatment plant laboratory.

Work involves conducting technical laboratory tests and examinations of substances obtained through various sampling techniques, as well as performing chemical analyses using automated and computer controlled spectroscopic and chromatographic instrumentation. Work is performed in accordance with systematized theory, scientific principles, laboratory techniques and controls to insure accurate and verifiable results. Work includes making scientific identifications of suspected pollutant substances gathered by air and water sampling equipment and water quality control. Duties occasionally require contact with contaminated, corrosive or toxic materials. Supervision may be exercised over subordinate laboratory technicians who assist with the basic laboratory tests and analytical procedures. A professional superior reviews test results for qualitative findings and assists in procedures where abnormal or difficult analysis are indicated.
