<p>Environmental Engineering is easy to get into. In the US, all you really need to get your foot in the door is a degree in any kind of engineering, chemical or biological science, a 40 hour HAZWOPER class, and an 8 hour HM-181 class. So, there is a lot of competition for jobs. Knowing the EPA, DOT, and OSHA legal regulations is as important as knowing the science,. Also, make sure you know the regulations for the local job market, air pollution, wastewater, stormwater, hazardous waste and hazardous materials management is typically delegated to local counties, cities, and state agencies, each with its own set of regulations. Most of these rules and regulations can be found online. Study up, and you can talk your way into a job. :)</p>
