CITY OF PHILADELPHIA PERSONNEL DEPARTMENT
AQUATIC BIOLOGIST I
This is aquatic biology work of limited scope and difficulty identifying and studying biota and bio-systems associated with water purification and/or pollution control to determine the causes and effects
of contaminants and the means of their control.
Work includes field sampling research at watershed and stormwater overflow sites as well as in plant and delivery systems. The employee is given progressively more difficult assignments and is expected to use progressively more independence of judgement in conducting biological tests. Work is performed under the supervision of an Aquatic Biologist Supervisor.
Work 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 perform aquatic biology work of limited scope and difficulty, identifying and studying biota and bio-systems associated with water purification and/or pollution control.
- The 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 such as sludge receptacles, digestors, reservoirs, and distribution networks; based on such findings, 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.
- Performs related work as required.
