NATURE OF WORK
This is scientific work in performing laboratory analysis for air and water pollution control or at 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 wastewater, and water sampling. 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 analyses are indicated.
Supervises and participates in a wide variety of professional chemical and bacteriological tests and analysis in connection with the operation of water and wastewater treatment plants.
Performs chemical and microbiological analyses of water and wastewater for various pollutants harmful to humans, plants, fish and animals.
Performs metals analyses by atomic absorption spectrophotometry, nutrient analyses by automated analyzer and purgable organics by gas chromatography.
Conducts particle identifications including dust, pollen, and algae.
Furnishes technical information regarding water supply purification program to various officials and the general public; advises water and wastewater treatment personnel regarding chemical problems.
Performs physical and chemical tests and analysis of unknown substances by qualitative and quantitative procedures; identifies present or potential pollutant elements and submits findings in laboratory report.
Prepares standards and reagents.
Examines air samples to determine presence of toxic vapors, collects particulate samples to ascertain concentration levels.
Performs chemical and bacteriological analysis of water samples to determine presence of effluents, pollutants and various toxins harmful to plants, animals and humans.
Conducts gravimetric and colorimetric analyses.
Determines chemical and physical composition and properties of compounds utilizing and spectrophotometry; identifies unknown elements by observing and recording characteristic spectra.
Ascertains relationships between molecular structures and chemical and physical properties to aid in analysis of unknown compounds.
Prepares chemical reagents for field studies and laboratory analysis; maintains inventory of laboratory equipment and supplies; maintains sample logs and compiles statistical data.
Records and tabulates test data and prepares reports.
Prepares and submits written analytical reports of laboratory findings and recommends repetition of testing and corrective action in abnormal findings.
Performs related work as required.
