Summers interviewed on Colorado biochar facilty Jeff Zehnder Mon, 02/09/2026 - 13:53

Scott Summers was interviewed for a new article about biochar in the Canon City Daily Record.

The piece is centered on the economics of a new publicly-run biochar facility in Douglas County.

Summers is a professor emeritus in the Environmental Engineering Program and expert on water reuse and sustainability. He has been experimenting with biochar production for more than two decades.

Biochar is a carbon-rich, charcoal-like material that can used to purify water. It is made from dead trees and plant material, the removal of which can potentially reduce wildfire risk, a major attraction for Douglas County.

Karl Linden recognized as Distinguished Professor at campus ceremony Jeff Zehnder Mon, 02/09/2026 - 09:08

Karl Linden, chair of �鶹��Ѱ��Boulder’s Department of Civil, Environmental and Architectural Engineering and the Mortenson Professor in Sustainable Development, has been named a Distinguished Professor, the highest faculty honor awarded on the �鶹��Ѱ��system’s four campuses. The recognition was presented to Linden and five others by Chancellor Justin Schwartz at the University of Colorado Board of Regents meeting on Feb. 6.

“When I came to �鶹��Ѱ��Boulder 20 years ago, I was attracted by the collaborative spirit, focus on environmental sustainability and the amazing students this university was able to attract,” Linden said. “The colleagues I have been able to work with, the support from administrators and the creative and aspirational students that I have been able to mentor, have all enabled my successes. Being named a Distinguished Professor is a direct result of the incredible people I have been able to work with in Colorado.”

�鶹��Ѱ��Distinguished Professors are tenured faculty members who demonstrate exemplary performance in research or creative work; a record of excellence in promoting learning and student attainment of knowledge and skills; and outstanding service to the profession, the university and its affiliates. Including this year’s seven honorees, only 160 Distinguished Professors have been named since the title’s establishment in 1977.

Advancing the field

Linden’s career has focused on innovative ways to improve water quality and water treatment. He’s known as an expert in ultraviolet light disinfection systems, now used by many municipal water systems.

He currently serves on the World Health Organization (WHO) Water Quality Technical Advisory Group. As a faculty member, he has taught hundreds of students in water and wastewater treatment, water and sanitation in developing communities, and graduate courses in water reuse and advanced treatment. He has authored more than 260 technical papers and has been honored with many high profile awards, too numerous to mention them all.

In 2023, Linden was honored with the Lifetime Achievement Award at the International UV Association (IUVA) World Congress, hosted in Dubai. During the event, the IUVA president called upon those who have worked with Linden, been his student or read his papers to stand.

"It was one of the sweetest moments of my career," Linden said at the time. “Almost the whole room was standing. It was overwhelming and humbling."

Most recently, he received the American Water Works Association’s 2025 A.P. Black Research Award, which honors outstanding contributions to water science and supply, and appeared on the cover of the organization’s journal.

Linden has also been recognized as an elected Fellow of the American Association for the Advancement of Science (AAAS) “for distinguished contributions to the field of water treatment engineering, particularly for using ultraviolet light for pathogen disinfection and abatement of organic contaminants in water reuse.” During a Fulbright fellowship, he researched solutions to water pollution in rural and First Nations communities in Nova Scotia, focusing on the water quality challenges faced by those living in remote areas, including those without reliable access to safe running water or conventional sanitation.

During the COVID-19 pandemic, Linden and his researchers identified a specific wavelength of ultraviolet light that is effective at killing the virus and is safe for use in public places like concert halls and airports.

In 2020, he won the Borchardt-Glysson Water Treatment Innovation Prize and was named the Clarke Prize Laureate for outstanding achievement in water science and technology. In 2014, he was named the Water Reuse Foundation Person of the Year.

Early inspiration and education

Linden grew up in New York City. After being exposed to the environmental sciences in middle school, he decided to pursue a degree through Cornell University’s environmental engineering program in the College of Agriculture and Biological Engineering. While there, he learned how to drive a tractor and spread manure, which he said was “quite unique for a New York City kid.”

Linden left Cornell midway, not seeing the connection between his math and physics classes and his desire to protect the environment. Several years later, a serendipitous reading of a New York Times article about a Cornell professor, Bill Jewell, who purified water by growing plants in a constructed wetland, brought him back to Cornell. Inspired by Jewell’s class in biological waste management and a research position in his lab, Linden went on to work for one of the lab’s spinoff companies before pursuing a master’s degree and a PhD on UV disinfection at the University of California Davis. Before coming to Colorado, he was a professor at University of North Carolina Charlotte and Duke University.

“I think a lot about the people and places that have influenced my career and set me up for success and greatly honor my past mentors,” Linden said. “The greatest testament to my successes is not how many publications or projects I have been a part of but the extent to which I have enabled the success of others–my colleagues and students–and to set them up to do great things for protecting public health and the environment. “

�鶹��Ѱ��Boulder Online welcomes new leadership as visioning process begins

Jeff Zehnder — Wed, 29 Oct 2025 15:35:51 +0000

�鶹��Ѱ��Boulder Online welcomes new leadership as visioning process begins Jeff Zehnder Wed, 10/29/2025 - 09:35

Following the departure of Robert McDonald, former dean of libraries and senior vice provost for online and extended education, Fernando Rosario-Ortiz, interim vice chancellor for academic resource management, announced in July that McDonald’s online education responsibilities would be restructured. This leadership transition marks a formal separation between University Libraries and �鶹��Ѱ��Boulder Online, paving the way for a renewed strategic direction.

Effective July 1, Randall Fullington temporarily assumed some of the tasks held by former Dean McDonald and continues to lead the Office of Academic and Learning Innovation (ALI) within the Division of Academic Affairs. Scott Battle, vice provost and dean of Continuing Education (CE), will partner with Fullington to ensure strategic alignment in serving �鶹��Ѱ��students and global learners in the online space. Rosario-Ortiz will serve as the administrative lead for �鶹��Ѱ��Boulder Online, reporting to and collaborating with Provost Ann Stevens.

Together, Battle, Fullington, Rosario-Ortiz, and Stevens are embarking on a visioning process to reimagine and strengthen �鶹��Ѱ��Boulder’s online programs, as the university continues to focus on the success of all students, faculty and staff. This visioning process will focus on developing strategies and processes designed to serve both campus-based students and broader national and global learners.

The following interview with Fernando Rosario-Ortiz addresses the background of online education and the goals for the visioning process for �鶹��Ѱ��Boulder Online.

The campus historically has had a scattered online presence throughout the university—CE, ALI, the graduate school, the colleges and schools and undergraduate microcredentials. What was the catalyst for a holistic review of our online offerings?

We’ve built a strong foundation in online education—including the formation of �鶹��Ѱ��Boulder Online—and I am thankful to those who led the way and have gotten us to where we are today. Now the provost has directed us to evolve our online model to be more scalable and sustainable, with the interest of supporting learners across different stages in their careers. Our goal is to create an online learning environment where students at all levels can more easily navigate campus resources while being intellectually challenged and supported throughout their journey, and where faculty can create rigorous and innovative coursework based on their research, scholarship and creative work. Ultimately, we seek to continue to expand the overall impact of �鶹��Ѱ��Boulder beyond our residential population, bringing our history of excellence in academics and research to other communities.

By undertaking a more holistic approach, what opportunities do you see for students, faculty, staff?

Our goal is to create an online learning environment where students at all levels can more easily navigate campus resources while being intellectually challenged and supported throughout their journey, and where faculty can create rigorous and innovative coursework based on their research, scholarship and creative work.

For students, to provide clearer opportunities to use online programming to complete their degrees, or to add skills and knowledge via microcredentials and industry certificates to enhance their degrees. For faculty, to provide the chance to innovate in their teaching and course development and reach new audiences in a more collaborative way. For staff, to be able to constantly upgrade their skills and knowledge, making their work and collaboration more enriching.

How does this vision process align with �鶹��Ѱ��Boulder’s institutional priorities?

This visioning process for our online education is a critical and timely undertaking for �鶹��Ѱ��Boulder and aligns seamlessly with two of our institutional priorities: fostering the success of all students, faculty and staff and aligning our resources and infrastructure to our mission to empower learners to thrive, innovate and lead in a rapidly evolving world.

Would you describe the timeline of this effort?

The provost and I have had conversations to clarify goals and expectations for the process, and I have started conversations with past and current leadership around online programs. Beginning in January 2026, I plan to engage with subject matter experts across campus—those who are envisioning the future, those who bring it to life and those who sustain it.

My aim is to have a well-defined, holistic vision in place by the end of spring 2026, with value-added changes beginning thereafter. We want the end result to make it easier for the campus community to engage in online teaching and learning, to have a clear sense of opportunities in this space and to add to the overall value of the academic experience �鶹��Ѱ��Boulder offers.

�鶹��Ѱ��Boulder professor joins global commission on indoor air quality Jeff Zehnder Mon, 09/29/2025 - 10:13

At the United Nations with Mark Hernandez and former student Patricia Fabian, now an associate professor at Boston University.

New Commission announced at the United Nations unites more than 170 leaders from over 30 countries to drive global action on healthy indoor air

Mark Hernandez is serving as a commissioner of the newly launched Global Commission on Healthy Indoor Air to elevate indoor air as a critical public health priority and drive coordinated global action and solutions.

Announced at the United Nations during Climate Week, the Commission brings together more than 170 global leaders from over 30 countries, including a former U.S. Surgeon General, global health authorities, senior scientists and researchers from leading universities as well as executives and sustainability leaders across design, real estate, technology and manufacturing.

Hernandez, a �鶹��Ѱ�� professor, is an expert on the characterization and control of microbiological air pollution.

He joins colleagues from around the world in developing a Global Framework for Action and catalyzing the creation of national Blueprints to strengthen indoor air quality efforts across regions.

“This commission is about reaching consensus on indoor air quality regulations and ensuring any regulations that emerge are based in sound science and are sustainable,” Hernandez said.

Indoor air pollution is associated with nearly 3.2 million premature deaths annually and contributes to a wide range of chronic and acute health conditions including respiratory illness, cardiovascular disease and cognitive decline. Despite the risks and the fact that people spend 90% of their lives indoors, indoor air quality has historically lagged behind other public health and environmental priorities.

“After generations of failures to attain indoor environment regulations, it appears there is enough political momentum to finally do so. Unfortunately, it took the consequences of a modern pandemic, catalyzed by airborne disease transmission, to get us here,” Hernandez said.

The Commission will:

Elevate a global call to action that places healthy indoor air at the forefront of public health and policy priorities
Build global awareness by highlighting the urgent human and economic costs of unhealthy indoor air
Establish a Global Framework for Action with clear prescriptions across key pillars of market transformation
Catalyze country-specific National Blueprints in collaboration with local stakeholders
Spur multi-sector investment to scale affordable, effective and equitable solutions

The Commission’s Global Framework for Action will be released by the end of 2026, alongside national Blueprints published on a rolling basis.

Supporting the academic enterprise Jeff Zehnder Tue, 06/24/2025 - 08:43

Interim Vice Chancellor for Academic Resource Management Fernando Rosario-Ortiz reflects on new role and areas of focus for upcoming year

Interim Vice Chancellor for Academic Resource Management (VC ARM) Fernando Rosario-Ortiz took over the position on April 1, 2025 after former VC ARM Ann Schmiesing moved to become interim vice chancellor for strategic initiatives under Chancellor Justin Schwartz in March, and then was named to the permanent post on June 9. The Provost’s Post talked with him to learn more about the position, what made him want it, and areas of focus for the upcoming year.

Question: How do you see the role of the vice chancellor for academic resource management serving the university?

Answer: The VC ARM principal focus is to determine, enhance and align the financial and physical resources available to support the academic mission of �鶹��Ѱ��Boulder. As such, I get to work with different academic units and other constituent groups on campus with the ultimate goal of supporting a successful academic enterprise. Specifically, I support efforts around usage of academic space, budget model, compensation and online and graduate education.

What made you want to do the job?

During the past eight years I have served in different leadership positions at �鶹��Ѱ��Boulder, starting with leadership positions at the environmental engineering program, then as associate dean for faculty at the College of Engineering and Applied Science, and most recently as interim dean for the School of Education. In these roles, I have had an opportunity to learn about what makes �鶹��Ѱ��and its programs thrive and be impactful.

Serving in a leadership position at the School of Education gave me the opportunity to appreciate how different units function and how ultimately the different parts of the university work together toward achieving the overall mission and goals at CU. As a result, I was interested in continuing to serve in leadership, but at a campus level, where I would have the opportunity to support all units and the broader mission of CU. Provost Moore supported my interest and felt I was right for the interim role, so here I am.

Do you have a basic philosophy, approach or set of guiding principles that guide your work in this role?

I strongly believe in the benefit of working collaboratively towards achieving goals. Ultimately, I see myself as a problem-solver and a strategic thinker, but with a clear understanding that problems are better solved with a strong sense of direction, clarity and vision that is informed by opening spaces for ideas from stakeholder groups and by supporting people. In my new role, I look forward to addressing challenging opportunities by working together with different groups as �鶹��Ѱ��continues to grow in impact both locally and globally.

How does the job interface with other academic units and leaders on campus?

Given that my portfolio is centered in resources—money, physical infrastructure and other assets I get to work with different unit leads and other stakeholders on campus. For example, I get to be part of discussions about space utilization and development of new academic spaces, as well as thinking through how to best support units as they grow and continue to adapt to a changing environment. I have enjoyed these interactions so far and look forward to continued conversations with folks around campus.

What are you seeing as the top three to five areas you’ll be focusing on in the 2025-26 academic year?

During the next academic year, I will be working to support efforts around the continued evolution of the budget model, compensation strategy and online education, among other areas of emphasis both ongoing and yet to emerge.

The end of lead pipes: An engineer’s take on the historic national effort to eliminate them

Jeff Zehnder — Wed, 30 Oct 2024 20:04:25 +0000

The end of lead pipes: An engineer’s take on the historic national effort to eliminate them Jeff Zehnder Wed, 10/30/2024 - 14:04

The U.S. Environmental Protection Agency (EPA) announced this month that it will require utilities to replace all lead drinking water pipes serving customers in the country within the next decade, marking the most aggressive regulation on lead in drinking water to date.

“This new rule is part of a progression of not just trying to treat a symptom but going back to the source and removing that material from our everyday use,” said Julie Korak, assistant professor in the Department of Civil, Environmental and Architectural Engineering.

The rule comes a decade after the water crisis in Flint, Michigan, when the city’s failure in water treatment exposed nearly 30,000 schoolchildren to lead, a neurotoxin that can impact children’s brains and nervous systems.

The EPA estimates that there are more than 9.2 million lead service lines—underground water pipes that serve water from public pipes into properties—in communities across the country. If a structure was built before 1986, there's a higher chance it has a lead service line, Korak said. To support this effort, the EPA has announced $2.6 billion in new funding. While replacing all these pipes will be a huge undertaking, it needs to be done, she added.

“We have to recognize that there are disparities where the presence of lead service lines disproportionately impacts disadvantaged communities. To promote equity across our country in terms of what kind of environmental hazards we're exposed to, it's important to address this disparity.”

The municipal government of Boulder recently announced that the city has no lead service lines after conducting a two-year inventory. Denver Water, the utility serving the city, has replaced 24,000 lead service lines, about a third of the estimated total, by July 2024.

As water utilities around the country race to identify and replace lead service lines, �鶹��Ѱ��Boulder today sat down with Korak to chat about the new rule and how individuals can protect themselves from lead in water.

Why is lead in water such a concern?

Lead is a toxic element. Unlike some other contaminants of concern, there is no safe level of lead, which means that there's no concentration or dose below which we don't experience adverse effects.

When lead from water pipes leaches into the water that we consume, it can have harmful toxicological effects, especially on children, such as low birth weight and adverse cognitive impacts. Exposure to lead during their developmental stages can be particularly adverse to their health. While it will be costly to replace all the lead service lines, the EPA analysis shows that benefits outweigh the cost in this case.

How does lead get into the water?

Lead has been used as pipe material for centuries, dating back to Roman times. It’s a soft, easy-to-mold material, which makes it ideal for shaping into durable pipes. But over time, the pipes can corrode, dissolving lead into the water. In addition, as water flows through the pipes, it can dislodge small particles of lead, which are then carried by the flowing water to consumers.

What is being done currently to minimize the impact of lead pipes?

Under the Safe Drinking Water Act, the Lead and Copper Rule has been in effect since the early 1990s. The EPA requires utilities to take steps to test for lead in drinking water, identify homes with lead service lines, and adjust water treatment methods to decrease lead release if the lead levels are above a certain threshold.

However, there is a recognition that as long as these lead service lines are present, they pose a potential risk, and a long-term plan to remove this potential risk is in the best interest of public health.

This new regulation is not to say that the previous methods have not worked. Tests have shown a decrease in blood lead levels across the country over the last 50 years. This decrease comes from a combination of different regulations to remove lead from not only water pipes, but also gasoline and paint.

How are lead pipes being replaced?

Replacing service lines will be a continuous effort with dedicated teams for impacted communities. If you start doing some of the math for average-sized communities, utilities need to be replacing a line every other day, for the better part of a decade, to make it happen. Larger metropolitan areas would likely need a more aggressive schedule.

One of the first challenges is determining how many pipes need to be replaced and where those pipes are located. Some communities may have good records of what pipes were used during construction. Some may have almost no records at all. In those cases, utilities will look at when buildings were constructed and what materials would have most likely been used at that time. They may visit sites and dig up a portion of the front yard to inspect materials, or request to go into a basement to see what kind of material is coming into the home.

Most utilities will replace lead service lines with copper pipes. Although also a metal, copper does not have the same adverse health impacts. From a regulatory perspective, the concentrations at which we become concerned are orders of magnitude different between lead and copper. For lead, concentrations above 10 micrograms per liter will trigger action. The action level for copper is just over one milligram per liter.

What can individuals do in the meantime to protect themselves from lead?

If someone is concerned that they might be exposed to lead from service line, there are filters that are certified to remove lead, both the dissolved lead and the small particles. It's important to purchase the filters from a reputable vendor and make sure that it's certified by NSF for lead removal. Larger utility companies will likely have a resource page on their website that recommends types of filters that are effective against lead.

Research shows air filters in classrooms improves overall ventilation and air quality Anonymous (not verified) Mon, 08/19/2024 - 14:17

Mark Hernandez's air quality research is being highlight by Denver 9 News.

The work which initially focused on reducing the spread of COVID-19 in Denver Schools during pandemic is now expanding beyond concerns of just infectious diseases and helping to improve air quality in schools across the state.

Hernandez is a professor in the Environmental Engineering Program and air quality expert.

"We now have data from ventilation performance for buildings all over the state. The good news was, we found out a lot of our buildings and classrooms are high performing. They have really good air quality and they really didn’t need the air cleaners," Dr. Hernandez said. "Others are less performing and when we put those in, we found out they helped ventilation systems do their job."

Ryan interviewed on mine wastewater research Anonymous (not verified) Thu, 07/25/2024 - 15:56

Joe Ryan spoke to the Colorado Sun about the use of viruses to kill bacteria in mining wastewater.

This wastewater, which can come with radioactive, cancer-causing materials, and yes, bacteria, often gets shoved back underground for storage. But increasingly, Colorado and other states are looking at ways to clean the wastewater enough that it can be used in other mining operations instead of fresh water. It’s an intriguing idea in Colorado, where fresh water supplies have been strained by a two-decade megadrought.

However, Ryan, an expert on contaminant fate and transport in waterways who was not involved in the research, has significant doubts about the utility of the development.

“It’s a questionable solution to a problem that just doesn’t seem at the top of the list of importance if you’re trying to do something with produced water,” Ryan said.
