I worked for several different consulting firms while I was doing environmental engineering, from a 200 person company to a 20,000 person company. At first I worked on small parts of big projects related to developing oil and gas from coal. Later I worked on the design of municipal water and wastewater treatment plants, then investigating old hazardous waste disposal sites and evaluating the damage they caused to human health and the environment. After I completed my master's degree and obtained my professional engineering license, I moved into a project management role, planning work and directing teams of engineers and scientists to complete the project. I've spent a lot of time writing plans and reports and making presentations to clients and regulatory agencies. Now I organize and manage different types of projects.
