Environmental Engineer

What is an environmental engineer? Environmental engineers devise effective solutions to issues involving pollution, public health, and sustainability. At the same time, you also research how human decisions can impact different environments, leading to issues like drinking water contamination and acid rain.

As an environmental engineer, your mission is to use a combination of engineering, soil science, biology, and chemistry to develop solutions to environmental problems and improve the quality of the world around us.

At a Glance

Imagine you’re standing in a field looking towards a mill. You’re being briefed on the project to upgrade the mill, which is nearly 40 years old and in need of another retrofit.

You are an environmental engineer, and you have been brought into this project to look at how the mill disposes of its effluent.

One of the by-products of the mill’s manufacturing process is effluent water that is too contaminated to be put into the municipal sewer system or discharged into local rivers. Your job is to examine this effluent and design a system to treat and disinfect the water before it can be discharged to the receiving body.

Your first task will be to test the mill’s effluent to determine exactly what is in the water. You look for chemical contaminants that are used in processing pulp and manufacturing paper, such as bleach. You will also test for biological oxygen demand (BOD), total suspended solids (TSS), and turbidity.

Once you know the types and concentrations of contaminants in the effluent, you can begin to design a treatment system. You will incorporate several methods, for example, filtration and ozone disinfection, to remove these toxic contaminants. Your goal is to design a system that will treat the mill’s effluent water so that it is clean enough to flow straight into the local river without any harmful effects.
