 Laboratory Technologist Microbiologist   Trace Analyst Compliance Inspector  Environmental Sampler Industrial Monitoring Erosion &Sediment Control


Laboratory Technologist – performs a variety of analyses on samples for process control, routine monitoring, and licensing compliance. Data from laboratory analyses is used by operators to make adjustments within the plant to ensure high quality effluent. Analyses can range from simple pH readings to more technical Total Phosphorous determination. Routine tasks may include:

  • Sample collection and preparation
  • Performs all tests required on each sample
  • Prepare reagents and standards needed for analysis
  • Reports results to operators, stake holders, and governing organization
  • Perform Quality Control checks on equipment and for each test as required


Microbiologist – performs critical analysis for the presence or absence, and counts of pathological bacteria, viruses, parasites and other biological organisms. The data is required for compliance with regulations and for process control. The rivers, watersheds, water and wastewater treatment plants, and the distribution system are regularly monitored. Genotyping work, microscopic examination are used to examine groups and species such as Fecal Coliforms, E. Coli, Cryptosporidium, Giardia. They also maintain active knowledge of new trends, regulations, and methodologies. They provide technical expertise to customers as well as the public. Similar to the laboratory technologist, tasks include:

  • Sample collection and preparation
  • Performs all tests required on each sample
  • Prepare reagents and standards needed for analysis
  • Reports results to operators, stake holders, and governing organization
  • Perform Quality Control checks on equipment and for each test as required


Trace Analyst – perform low-level instrument analyses of trace organic compounds. Knowledge, maintenance and utilization of sophisticated instruments such as gas chromatography-mass spectrometres (GC-MS), liquid chromatography-mass spectrometry (LC-MS), inductively coupled plasma mass spectrometry (ICP-MS) is common. Their work helps allay concerns about metals, pesticides, herbicides, disinfection by-products, pharmaceuticals and other trace contaminants in the drinking water as well as for river health. Tasks include:

  • Sample collection and preparation
  • Performs all tests required on each sample
  • Prepare reagents and standards needed for analysis
  • Reports results to operators, stake holders, and governing organization
  • Perform Quality Control checks on equipment and for each test as required


Compliance Inspector – performs field work to ensure compliance with bylaw and regulations. If bylaws are contravened, then samples are taken to assist in the litigation process. They work closely with the Wastewater Treatment Plants to investigate and help trace potential sources of plant process alerts and upsets. They also work closely with Bylaw Officers on sources of non-compliance with respect to Sewer Service Bylaws.



Environmental Sampler (Watershed, Stormwater) – perform field sampling to help monitor changes up and downstream of treatment plants as well as help assess impacts of treatment technologies. They support the environmental and watershed monitoring programs, in conjunction with various stakeholders to support great quality drinking water and to maintain and preserve the riparian habitats. Some of this work is carried out to meet regulatory requirements tied into total loadings management, as well as to monitor levels of dissolved oxygen that is imperative to river health.



Industrial Monitoring – monitor numerous sources of discharge to the sanitary system from industry, commerce, and large institutions such as hospitals and universities (ICI). They may help administer and support groundwater disposal programs, Fats, Oils and Grease (FOG) Management Programs, and a toxicity evaluation program to screen industrial wastewater. Regular communication with citizens, the business community and other associations is necessary in this job.



Erosion and Sediment Control – plan and implement programs to reduce sediment loading and other pollutants. One may be called out to subdivisions, private developments, construction sites, stripping and grading sites for inspection prior to evaluating and issuing permits. Issuing drainage and dewatering permits usually demands a close review of the water quality, and effective systems in place to treat the water.
