WATER SYSTEMS CHEMIST II 22160
(Competitive)
DISTINGUISHING FEATURES OF THE CLASS
The work involves responsibility for analyzing water of a potable water treatment facility and transmission system to control processes, which make water suitable for drinking. An employee in this class is responsible for maintaining required quality standards in the treatment of water for the Metropolitan Water Board of Onondaga County (MWB). Considerable leeway for the exercise of independent judgment is allowed in carrying out technical aspects of the work. The employee supervises and participates in the conduct of analytical and laboratory procedures in the examination of water samples for purposes of determining and maintaining water quality. Procedures typically include bacteriological and biological tests as well as chemical tests. The employee operates a variety of scientific equipment in performing chemical analyses. An employee in this class is responsible for conclusions and findings. General supervision is exercised over a small number of laboratory personnel. Supervision is received from an administrative superior responsible for water plant operations. Does related work as required.
