CITY OF PHILADELPHIA PERSONNEL DEPARTMENT
AQUATIC BIOLOGIST II
This is aquatic biology work at the full performance level identifying, monitoring, studying, and analyzing biological life in water, wastewater, sludge products and industrial waste.
Work includes field research at watershed and stormwater overflow sites as well as in plant and delivery systems. Work is performed under the supervision of an Aquatic Biologist Supervisor, and includes
some disagreeable aspects.
ALLOCATING FACTORS: (The following conditions must be met for a position to be approved for this class.)
- Positions in this class must be responsible for performing aquatic biology work at the full performance level, identifying, monitoring, studying, and analyzing biological life in water, wastewater, biosolids products and industrial waste.
- Positions in this class must be located in the Water Department.
TYPICAL EXAMPLES OF WORK (ILLUSTRATIVE ONLY)
- Conducts bacteriological examinations such as heterotrophic bacterial plate count, total and fecal coliform presence by accepted procedures; takes field samples at local and remote watershed and storm overflow sites; analyzes and identifies aquatic organisms including protozoa and bacteria, plankton, periphyton, macrophyton, and macroinvertebrates; establishes test statistics and quality assurance.
- Investigates the distribution and interrelations of aquatic organisms in rivers and at various points in processing systems including sludge receptacles, digestors, reservoirs, and distribution
networks; conducts chemical and biological tests to determine means of improving water quality, or pollution control processing.
- Provides information for the conduct of detailed field investigations; devises tests to demonstrate the effects of waste discharges on the ecology of the watershed; prepares detailed reports of findings including statistical analyses; reviews current scientific literature related to work assignments.
- Interacts with chemists and engineers from other sections to interpret laboratory data, design biological studies and establish needs for services.
- Calibrates and maintains laboratory equipment; prepares reports and maintains records of tests performed.
- Instructs work-study interns in practices, procedures and theory of aquatic biology; assigns biological tests, reviews the work by checking results and observing techniques; corrects students using improper methods and aids in the solution of any problems encountered.
- May assign standard biological determinations to a small group of laboratory personnel; reviews work by checking results, assigning retests and duplicating tests.
- Performs related work as required.
