Environmental Technician/ Technologist

Environmental technicians/technologists work on projects to assess, clean up, and protect the environment. They require broad scientific knowledge and technical skills and can be involved in a variety of projects. For example, environmental technicians/technologists can be responsible for collecting and analyzing air, water, and soil samples; conducting field inspections and investigations of contamination; operating and monitoring pollution control or treatment equipment; monitoring compliance with federal and provincial regulations; or participating in environmental assessments and cleanup efforts. Environmental technicians/technologists often work as part of a team of professionals and play a key role in conservation and protection efforts.

At a glance

Imagine you are working beside a busy highway interchange, carefully collecting and replacing air quality sampling tubes from a small monitoring station. You are an environmental technician/technologist working for a small environmental consulting firm that has been recruited by the City to coordinate its new air quality monitoring program. The program is designed to measure levels of air pollutants in different areas of the city and compare them to national air quality standards. Months ago, you and your team mapped and built a number of monitoring stations to effectively test problem areas. Now it is your responsibility to collect samples from these stations each week and make certain they are functioning properly. As an environmental technician/technologist, you are often responsible for collecting and processing a variety of air, water, and soil samples. For this project, you collect air quality samples using diffusion tubes placed at each monitoring station: air enters the tubes and a chemical absorbent traps any pollutants present. Each week, you collect the old tubes for analysis and replace them with new ones. Some monitoring stations are also outfitted with more advanced sampling equipment that uses filters to collect pollutants. Regulated volumes of air are pumped through specialized filters that trap pollutants for detection and analysis. As with the diffusion tubes, you must regularly collect the old filters and replace them with new ones. Once you have collected the samples, you take them to the lab for analysis. You and your team of environmental professionals will evaluate the results and compare them to national standards, which will tell you if you the city’s air quality levels are above or below legal limits. Finally, you will contribute to the preparation of a report summarizing your firm’s findings that will be presented to the City.

Role Model

Brad Wynne

"I'm the kind of person who likes to feel he's helping out, getting things cleaned up a bit," says Brad Wynne of his job as an environmental engineering technician working for an environmental consulting firm based in Richmond, B.C. "I've always been interested in environmental issues. The more I looked at possible careers, the more this interested me. Now, after a couple of years in the field, I know I've made a great choice." Brad is also the kind of person who likes variety. "I like to do a lot of different things," he says. "My main thing is field work with water sampling, soil sampling, and compliance monitoring for our client companies. Then I write reports that go to the company or to the provincial government. Right now, I'm segregating soils and monitoring air contamination for workers at a particular site to make sure their working conditions are safe. " Much of Brad's work takes place out-of-doors where his sampling skills are the most important. When he returns to the office, another set of skills comes into play. "I use computer programs to record and tabulate data. Modelling programs are particularly important. They give you a picture of what is happening - for instance, with groundwater - over a large geographical area." "The great thing is that I'm never stuck in one thing for too long," Brad says. "It's just so variable. I could be doing something completely different next week."
