The senior design section (CEE 4905) advised by Dr. David Hand and Dr. Eric Seagren traveled on February 1, 2019, to visit the Plainfield Township Water Department’s treatment plant outside of Grand Rapids, Michigan. The plant is operating a pilot-scale study examining the removal of per- and poly-fluoralkyl substances (PFAS) from their water supply using granular activated carbon (GAC). PFAS compounds were invented in the 1930s and since then have been manufactured for a variety of uses including: nonstick coatings, stain and water-resistant products, protective coatings, and firefighting foam. These compounds are very stable in water, are persistent, bioaccumulative, and not known to degrade in the environment. In 2017, Michigan was one of first states in the country to begin to establish a clean-up standard for PFAS in groundwater when used as a drinking water source. The Michigan PFAS Action Response Team, made up of several state agencies, has worked to identify PFAS contamination in the state.
The purpose of this senior design project is to develop design guidance for the use of GAC for the removal of PFAS chemicals from water supplies. GAC is a Best Available Technology (BAT) as designated by the USEPA for removal of organic chemicals from water. In fact, GAC is presently being used in several of the sites identified in Michigan for removal of PFAS compounds. Design guidance for using GAC for the removal of these compounds is needed as it can provide regulatory agencies, consulting engineers, and water utilities with the tools necessary to effectively and economically evaluate the use of GAC for treatment of these chemicals. Therefore, the main objectives of this project are to: (1) evaluate the design of the pilot-scale GAC system that has been implemented at the Plainfield Township Water Department’s treatment plant, and (2) to develop a general design guidance for the application of GAC fixed-bed adsorption processes for the removal of PFAS from drinking water.
Jiaqing Wang attended the Transportation Research Board (TRB) 98th Annual Meeting at the Walter E. Washington Convention Center, January 13–17, 2019, in Washington, D.C. He presented his recent research work under Dr. Qingli Dai’s supervision. The presentation title was “Effectively Recycling Scrap Tire Rubbers into Epoxy Polymer Concrete as Overlays or Repair Materials.”
To reduce environmental landfill problems with the accumulation of tire rubbers, scrap tire rubbers were added to epoxy polymer concrete. The solid rubber particles (with mesh size #50) were introduced into epoxy concrete with two different contents of 5% and 10% based on the epoxy monomer weight. The test results indicated that the use of solid waste tires could not only enhance the performance of neat epoxy concrete, but also contribute to environmental protection while extending the service life of existing concrete structures. His presentation and the research work that was conducted in the Department of Civil and Environmental Engineering at Michigan Tech attracted the audience’s attention and interest.
Wang also attended the 9th International Association of Chinese Infrastructure Professionals (IACIP) Annual Workshop “Innovations of Transportation Infrastructure In an Era of Climate Change.” He received 2nd prize in the student poster competition.
Barkell Elementary School hosted Family Science and Engineering Night Wednesday evening, February 6, 2019, giving children grades K-5 opportunities to think outside of the box in the fields of science and engineering, with educational yet fun activities.
Brian Doughty of the Michigan Tech Center for Science and Environmental Outreach, led an activity in which fourth- and fifth-grade students explored generating electricity with a lemon.
Jennifer G. Becker (CEE) is one of the lead authors on a paper that defines the sustainability metrics that should be used to assess water resource recovery facilities of the future. The paper, which was just published in Water Environment Research, was a follow-up to a National Science Foundation-sponsored workshop to which Becker and other leaders in the field of water and wastewater treatment and reuse were invited.
The workshop focused on developing evaluation metrics to advance the Facilities Accelerating Science & Technology (FAST) Water Network. FAST includes over 90 test bed facilities dedicated to accelerating innovation and adoption of water energy, and nutrient recovery systems.

The recovery of water, energy, and nutrients from water resource recovery facilities (WRRFs) is needed to address significant global challenges, such as increasing water demand and decreasing availability of nonrenewable resources. To meet these challenges, innovative technological developments must lead to increased adoption of water and resource recovery processes, while addressing stakeholder needs (e.g., innovators, practitioners, regulators).
Sarah Washko, an environmental engineering MS student, participated in the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) Snow Measurement Field School on January 6-11, 2019, in Bozeman Montana. The NASA-funded course provided training for performing high-quality snow measurements in the field, as well as in the fundamentals of snow hydrology analysis. In addition to traditional field methods, remote sensing techniques were also explored.
Each day in the field concluded with a presentation of the day’s findings. The final day culminated in a student designed field campaign at the Bridger Bowl Ski area. The workshop was designed to cultivate snow measurement and research design skills.
At an awards program in the Memorial Union Ballroom Wednesday (Jan. 9, 2018), staff members were honored with the Staff Council Making a Difference Award.
Julie Ross, academic advisor, Civil and Environmental Engineering, was a recipient of the Unsung Hero Award. Julie’s nominator states “When the faculty member who established the CEE Student Success Center left the University, Julie picked up the role of advisor for this group because she knew the services provided by the student success coaches were essential to the Department’s teaching mission. Without her stepping up and taking the advisor reigns, this group would not exist today.
