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.
The Laboratory Technician / Senior Laboratory Technicians are responsible for the analysis of selected inorganic, organic, and microbiological targets using strict EPA and Standard Methods guidelines and procedures. They perform wet chemistry analysis and perform both inorganic and organic extraction procedures using EPA method 300 and 500 series and Standard Methods criteria. They are responsible for proper preservation of method sample bottles, performing sanitizing protocols, receiving, and distributing samples throughout the laboratory, ensuring proper chain of custody data and information, meshing of field and sample site information, and maintaining and utilization of LIMS databases. Lab Techs represent the first line of QA/QC support and techniques, which will impact the overall reliability of water quality data – from pharmaceuticals to pH. Senior level technicians are required to work more independently. They are responsible for student intern support and assisting in prioritizing their work functions.
