CLASSIFICATION NO. 786
Under direction, to perform complex chemical analyses on water, wastewater, industrial waste, and biosolids samples; to perform sample preparation and analysis; and to do other work as required.
The Water Quality Laboratory section within Water Environment Services provides physical, chemical, and biological analyses of industrial wastes, storm water, surface water, soils, bio-solid samples, septage wastes and wastewater. This classification may be used by other departments with laboratories.
The Laboratory Analyst is a professional journey level classification which performs varied and complex analyses including conducting the most complex metals analysis and toxic analysis of unknown substances. Incumbents report the results of testing to plant operations staff for plant management and process control to ensure compliance with federal and state regulations regarding effluent, biosolids handling, and surface water management. The Laboratory Analyst may train other plant personnel in specific laboratory operations.
The Laboratory Analyst differs from the entry level Laboratory Technician who assists in collecting samples and performing routine process control tests. It differs from the Laboratory Supervisor who has full supervisory responsibilities for all of the laboratories and lab employees.
Duties may include but are not limited to the following:
- Analyzes water, wastewater, industrial waste, and biosolids samples for oxygen demand, suspended solids, alkalinity, coliform bacteria, pH, nutrient levels, metals content, and other counts in accordance with standards of federal, state and local agencies; prepares chemical and bacteriological media, stains, reagents and test solutions routinely used in the laboratory.
- Prepares samples for testing using digestion and/or chemical reagents; conducts complex laboratory tests using a wide variety of equipment to determine concentrations of metals or other hazardous materials.
- Follows permits, federal, state, and local regulations and laws to develop testing procedures to meet those requirements; records results of analyses for compilation into test reports which are subsequently filed with state and federal water quality agencies; uses test results to calculate complex statistical reports and trending for process control.
- Maintains and calibrates laboratory testing equipment; operates and maintains analytic instrumentation.
- Ensures that safety regulations in the laboratory are followed.
REQUIRED KNOWLEDGE AND SKILLS
Thorough knowledge of: Principles of standard chemical, biological, microscopic and microbiological examination techniques; operation and maintenance of analytic instrumentation and other laboratory equipment; statistical methodologies to collect, analyze and evaluate data and perform short term studies on industrial waste, surface water, wastewater, and biosolids; principles of quality control; principles and concepts of work teams; sampling and sample preparation techniques; mathematics, algebra and geometry; English grammar, spelling and punctuation; microcomputer applications in wastewater treatment.
Skill to: Communicate effectively, both orally and in writing; read and interpret federal and state water quality regulations; comply with established laboratory testing programs; read, analyze and use complex formulas, charts, and directions; prepare comprehensive technical written reports; plan improvements in standard laboratory methods; prepare and maintain accurate records; establish and maintain effective working relationships with work team members, customers, contractors, vendors, County employees, and the public.
Within WES Department, duties require frequent standing, squatting, bending, reaching, fine motor control, accurate color perception, and the ability to lift up to 45 pounds, and carry, push and pull objects.
Duties involve exposure to bacteria, viruses and toxic material in wastewater, and handling chemicals and bacteriological waste matter.
Employment is contingent upon passing a post-offer physical assessment. Accommodation requests will be reviewed on an individual basis in compliance with State and Federal legislation.
Driving may be necessary for County business. For position(s) with occasional/incidental driving, incumbents must possess a valid driver's license. Accommodation requests for an acceptable alternative method of transportation will be reviewed on an individual basis in compliance with State and Federal legislation. For position(s) with regular driving, incumbent(s) must also possess and maintain an acceptable driving record throughout the course of employment.
MINIMUM RECRUITING STANDARDS
Any satisfactory combination of experience and training that demonstrates possession of the required knowledge and skills.
