A Chemist performs difficult organic, inorganic, and physical chemical analyses and research studies in connection with water quality, wastewater, storm water, solid resources, and industrial wastes. The Chemist I will operate the instrumentation used for chemical analysis, e.g., Gas Chromatograph with different kinds of detectors such as electron capture detector (ECD), Mass Spectrometer (MS), segmented flow analyzers, TOC instrumentation and other laboratory instruments. The Chemist I will perform chemical tests, which include testing for pesticides, PCBs, herbicides, volatile organic compounds (VOC), lipids, BOD, COD, TOC, nutrient analysis, and other environmental chemistry analyses.

Major duties are to perform sample preparation and analysis of water, wastewater, biosolids, tissue, sediment, industrial waste, and other environmental samples. Duties of this Chemist I may involve substantial use of organic solvents; set up of continuous liquid extraction, prepare organic and inorganic standards and reagents, and work standing in front of a ventilation hood for a substantial amount of work hours during a normal workday. The Chemist I may collect samples in the field. The Chemist I must be able to troubleshoot the problems of instruments and methodologies; maintain the instruments, and be familiar with the quality control requirements in chemical analysis. The Chemist I will support special studies with scientific expertise, and help the lab maintain compliance with standardized testing methods. The Chemist I will also help with data collection and data troubleshooting.


The Division is interested in candidates who possess the following skills, knowledge, and abilities including, but not limited to the following:
