Definition

Perform a variety of specialized chemical, biochemical, bacteriological, microbiological, and toxicity analyses of water, receiving waters, wastewater, and related solids and by-products relevant to wastewater collection, treatment, and disposal; collect samples; perform and/or assist in the conduct of complex research projects.

Chemist I

This is the entry-level class in the Chemist series and is distinguished from the II level by a more limited ability to perform the full range of duties as assigned without immediate supervision.  While positions in this class may have relevant work experience, they are generally less familiar with the specific policies and procedures unique to the District and the District’s laboratory operation.

Chemist II

This is the journey level class in the Chemist series and is distinguished from the I level by the ability to perform the full range of duties as assigned including the conduct of complex research projects which positions in the I level usually assist in.  Positions in this class are distinguished from the Senior level in that responsibilities do not include administrative or managerial duties relevant to the daily operation of the laboratory.
