He earned his BS (High Honors) and MS in Civil Engineering and his PhD in Environmental Engineering at the University of Wisconsin where he conducted research within the Small Scale Waste Management Project. Prof. Siegrist is an internationally recognized expert in decentralized water reclamation and in situ remediation of contami- nated land. During his 40-year career he has published over 300 technical papers and 3 books and was awarded 2 patents. His new textbook, Decentralized Water Reclamation Engineering, was just published by Springer (www.springer.com/us/book/9783319404714). He has given invited keynote

nature of the teams were such that each student neededto provide specific skills in order to complete the project. After completion of the course,the authors noted that a key concern was that the civil engineering students did notparticipate as much as the students from the other disciplines.Another potential issue with multidisciplinary capstone design involving civil andenvironmental engineers is the scale of the infrastructure design projects that arecommon in these disciplines. Frank et al.5 described a multidisciplinary capstone seniordesign project program at Florida State University. Their multidisciplinary programincludes mechanical, electrical and computer, and industrial and manufacturingengineering. The authors report that the program

effects of unconsidered energyconsumption, a knowledge of the physical laws governing and technologies behind conventionaland alternative energy production, and an array of tools to evaluate and implement energyconservation strategies on personal and corporate levels.To achieve these objectives, several projects were implemented calculating heat usage and heatloss during a winter month for a campus building, performing energy audits for the residences ina neighbouring community and calculating estimated energy savings. In addition, a term paperresearching atmospheric pollution and its sources and effects was required. This activity helpedstudents gain a deeper appreciation of the impact of energy-related choices, behavioral actions,and human

Each team wasasked to adopt a basic CDI reactor and were provided with basic material, equipment andsupplies and guidelines for the project. A salt solution was pumped through the reactors in acontinuously re-cycled (multi-pass) mode. The conductivity was measured in a reservoir.Students were asked to do mass-balance calculations on total quantity of the salt removedusing initial and final concentrations, and the volumes of the solutions used in theirexperiments. Students explored the effects of various operating conditions on desalination.The hands-on experience focused on design-build-operate approach starting from preparationof solutions of

Based on the Australian model, the Challenge, at RWTHAachen university, follows six phases (cf. fig. 1): 1. Engineers Without Borders (EWB) and the project team identifies relevant topics 2. EWB and the project team composes info material for students and lecturers 3. Lecturers integrate the topics into their lectures 4. In teamwork, students develop ideas and create solution concepts and afterwards write reports 5. Students present their concepts in front of a jury 6. EWB and the

One optionalterm project completes a Diplomacy Lab offering provided by the United States Department ofState [9]. And the other optional term project designs and executes a local community health fairevent as part of interprofessional education (IPE) in environmental health practice [24].

“report a lowersense of belonging” [34] in comparison to their white and male counterparts [35] – [37].Belonging to STEM fields is dependent on self-efficacy, which is the “confidence in one’sability to successfully perform a given task” [34]. For a mentee to feel positive about their field,the mentee’s perception of the relationship with the mentor is significant. Prunuske et. al. [30]determined that mentees’ confidence improved when they actively participated in researchprojects and acquired “the skills necessary for professional socialization.” They also determinedthat the personality of the mentor was more significant than the research project. In addition, thementees wanted mentors who would communicate and engage with them. When studying

to use tool for computing small site hydrology for any location within the US. It estimates the amount of stormwater runoff generated from a site under different development and control scenarios over a long term period of historical rainfall. The analysis takes into account local soil conditions, slope, land cover and meteorology. Different types of low impact development (LID) practices (also known as green infrastructure) can be employed to help capture and retain rainfall on-site. Future climate change scenarios taken from internationally recognized climate change projections can also be considered.The in-class activities lead students to a better understanding of green infrastructure, and

better matched their strengths and/or interests. Someof the students with the “biggest ideas” around advancing novel, environmentally-friendlydesigns were disappointed that the engineering courses seemed to be focused on teaching currentpractice rather than creative solutions. Given these findings, it might be impactful on retention tohave EnvE students take a course specific to environmental engineering and/or one that allowsthem to be innovative in envisioning solutions to problems of their interest (such as a project-based course that allows students to select a project of interest, and significant latitude increatively exploring solutions).Students who felt that their education should be more balanced between technical and societalissues

By the finalexam, however, the majority of the class remembered other methods, particularly, ion exchange.One possible reason for this is that students presented projects as a method of reviewing for thefinal exam. 80 70 Percentage of Students 60 50 40 30 20 10 0 Midterm Exam Final Exam

the matter is theEarth’s capacity to sustain a burgeoning global population which makes increasing demands onlimited resources [5]. Projections of resource exhaustion continually change based onimprovements in technology and consumer behavior. In 2017, global resource consumptionovershot the sustainable rate of use of a year’s worth of the Earth’s resources by early August.This day, observed as Earth Overshoot Day, occurs earlier each year [6]. At the present rate, thehuman population will consume two years’ worth of the Earth’s resources that can be sustainablyreplenished each year by 2034. Thus, ensuring a healthy environment in the future requiresembracing environmental sustainability. We define environmental sustainability as the ability
