There are many different paths that you can take as an "environmental engineer". Science is directly involved in all of these paths. My main focus is water resources and science definitely plays a huge role in that field. We have to understand a great deal of chemistry, to identify pollutants to water and soils and the subsequential environmental impacts. We also have to understand fish, wildlife and plant habitats when working in the water resources field of environmental engineering, a few examples where this is important are designing stormwater management structures, rehabilitation of dams, and wetlands creation or restoration. The best part of environmental engineering for me is being able to see, explore and create first hand in the field. I get to travel to locally to many different places.
