LABORATORY TECHNICIAN I
LABORATORY TECHNICIAN II
Class specifications are intended to present a descriptive list of the range of duties performed by employees in the class. Specifications are not intended to reflect all duties performed within the job.
Under general supervision, performs a variety of the physical, chemical, and bacteriological tests and analyses on a variety of environmental samples including but not limited to drinking water, raw water, wastewater, sludge, industrial wastewater, reclaimed water, and stormwater as necessary for process control and regulatory permit parameter compliance; collects samples; follows established practices and procedures to protect and assure the authenticity and reliability of data; and alerts appropriate personnel of any results outside of normal parameters in order for appropriate and timely actions to be taken to correct any problems in the treatment processes.
Laboratory Technician I – This is the entry level class in the Laboratory Technician series. Positions at this level have limited prior laboratory experience performing basic physical, chemical, and bacteriological tests and analyses and are not expected to function with the same amount of program knowledge or skill level as positions allocated to the Laboratory Technician II level and exercise less independent discretion and judgment in matters related to work procedures and methods. Individuals at this level are expected to become fully knowledgeable of the assigned area and to learn the full range of technical laboratory processes, procedures, and functions. As a condition of employment, incumbents must obtain a Grade I Laboratory Analyst Certificate issued by the California Water Environment Federation within 18 months of employment.
Laboratory Technician II – This is the journey level class in the Laboratory Technician series. Positions at this level require demonstrated ability to perform a variety of routine physical, chemical, and bacteriological tests and analyses and may assist in performing the more complex analyses. Positions in this class series are flexibly staffed and positions at the Laboratory Technician II level are normally filled by advancement from the Laboratory Technician I level. Positions at this level require two years of experience comparable to a Laboratory Technician I with the City of Escondido and must possess a Grade I Laboratory Analyst Certificate issued by the California Water Environment Federation.
