January 2, 2020

Gresham Smith is pleased to announce that Mark Liner, P.E., has joined the firm’s Water + Environment group. The Senior Environmental Engineer brings more than 25 years of government, technology and consulting engineering experience both in the U.S. and internationally in wastewater and airport deicer systems. He will serve as a project executive, leading stormwater and deicer projects.

“Known for his expertise in deicer management and an ability to build strong client relationships, we are proud that Mark has chosen to join our team of environmental expert at Gresham Smith,” said Jeff Nash, executive vice president, Gresham Smith. “His deep understanding of how to work with regulatory agencies and partners complements our existing staff, while adding value for our clients—ultimately supporting their environmental stewardship.”

“Having worked in the industry for many years, including teaming with Gresham Smith on several projects, I consider the team’s deicer management capabilities second-to-none,” commented Mark Liner, P.E., senior environmental engineer, Gresham Smith. “I knew that by joining the team I would have the opportunity to work not only with leading experts, but on larger-scale, multi-disciplinary projects. Through this work, I look forward to addressing our client’s complex issues and regulations.”

After serving in the Peace Corps in Nepal, Liner began his engineering career at the EPA where he contributed to industrial effluent guidelines and evaluated treatment technologies. Over the years, he has worked as a sales engineer and technology supplier, a project manager and a consulting engineer, including as a sole proprietor. During that time Liner worked on industrial and municipal wastewater treatment, waste management, remediation and stormwater and deicer management projects. However, his particular focus has been on stormwater and deicer systems at airports including Cincinnati/Northern Kentucky International Airport, Dublin International Airport, Nashville International Airport and Heathrow Airport.

As a subject matter expert, Liner has contributed to research for the Airport Cooperative Research Program (ACRP), a program managed by the Transportation Research Board (TRB) of the National Academies of Sciences, Engineering, and Medicine and sponsored by the Federal Aviation Administration. He has presented at industry conferences such as WEFTEC and contributed to publications including Airport Business and CE News.

Liner earned his Bachelor of Science degree in Civil Engineering from Lehigh University and his Masters of Engineering in Environmental Systems Engineering from Clemson University. When he’s not working on water quality projects at airports, you’ll find Liner putting his engineering skills to good use on his old house or canoeing the Boundary Waters in Minnesota.
