Environmental Services is the branch of engineering that is concerned with protecting people from the effects of adverse environmental effects, such as pollution, as well as improving environmental quality. GSG provides the information needed to create usable assets as well as safely managing materials for industrial clients, developers, municipalities, and governmental agencies. Environmental engineers use core engineering skills and a deep understanding of the physical, chemical and biological principles of the local, regional and global environment to help change the world. GSG has evaluated and implemented remedial actions at hundreds of sites throughout the country including those with a long history of varied uses. Our team of scientists and engineers are experienced in assessing and managing environmental impacts at commercial and manufacturing facilities, rail and transit facilities, military installations, manufactured gas plant sites, and abandoned and licensed waste disposal sites. This has led to our expense with numerous sources of contamination and a range of contaminants. Understanding that there may be many potential solutions toward remediation and/or site closure, we develop strategic solutions that are the most cost-effective way to meet your objectives and ensure regulatory compliance with applicable regulations.
