The mission of this unique program is to provide a quality graduate education with core environmental engineering curricula supported by electives that focus on water reuse. The mastery of both principles and practices is emphasized, which prepares students for a dynamic career path in the water sustainability arena
Our Environmental Engineering (EVEN) Program has always had a water reuse component and we have recently formalized our approach to water reuse in response to this growing and evolving field. Our last four faculty hires have a water reuse focus and they complement existing faculty in our research and teaching efforts. The program curriculum has been developed and is taught by EVEN faculty and senior professionals with water reuse experience and expertise. All courses are currently offered in person, as well as online in a synchronous environment. Specialization in either advanced treatment technology or water reuse management is available through elective courses.The Water Reuse Program offers several options for enrollment:
Water Reuse Program Short Course
We are pleased to also announce a Spring Short Course in Water Reuse which will be held virtually on March 30, 2021. This 5 hour event is designed to educate young professionals and practicing engineers in the fundamentals of water reuse treatment with a focus on potable reuse. It is recommended that attendees have a basic understanding of drinking water and wastewater treatment. The course is taught by CU Boulder professors and nationally-recognized experts, Dr. Mark LeChevallier and Doug Owen, and covers regulations, pathogens, chemicals of concern, and treatment technologies. It looks beyond the typical approach to water reuse and covers planning and implementation.

Dr. Becker has conducted pilot studies, evaluated treatment systems, performed conceptual design for the development and optimization of water treatment systems, and trained employees, operators, and graduate students in various water treatment plant processes. He has consulted for some of the largest utilities in the country including Denver Water, New York City, Philadelphia, Washington Suburban Sanitary Commission, Baltimore, DC Water, Tampa, and Fairfax Water.
R. Scott Summers, Professor
Dr. Summers began working with reuse while at the US EPA in 1977-79 evaluating physical chemical treatment of wastewater with coagulation and granular activated carbon (GAC) adsorption. In 1980 he was part of a team that assessed the use of ozone and GAC for treating wastewater effluent prior to groundwater injection at a 1.0 MGD demonstration reclamation facility in California, and presented these results at the AWWARF Water Reuse Symposium in 1981, with additional presentations at AIChE and ACS meetings in 1982. In the past four years he has had three PhD students and one MS student evaluating the biochar and GAC adsorption and biofitration of greywater, stormwater, wastewater effluents and CSOs for the removal of specific organic compounds. In that same time he has had three graduate students and a postdoc evaluating the coagulation, ozonation, biofiltration and GAC adsorption of disinfection byproduct (DBP) precursors (both regulated and unregulated) from the effluent of treated municipal wastewater. Currently, three of his graduate students are evaluating the control of preformed DBPs in several reuse scenarios. He has over 30 reuse publications and presentations.
Dr. Linden is an expert in water quality and treatment, specifically related to beneficial reuse of impaired waters including analysis of water quality constituents and design of tailored treatment systems to meet reuse needs that are fit for purpose. His work and expertise on electrified water treatment processes such as UV, advanced oxidation and ozonation for both remediation of organic contaminants and disinfection of pathogens is known internationally. Most recently he has been working in reclamation of water from conventional and unconventional oil and gas development and has a long history of municipal wastewater reuse research. In 2014 he was the WateReuse Association’s Person of the Year and has won numerous awards for his research accomplishments.
Dr. Hernandez maintains an active sanitary engineering consulting practice focused on troubleshooting biological wastewater treatment processes. Dr. Hernandez holds several University of Colorado materials and methods patents that are licensed to companies for the treatment of mining and industrial wastes. Dr. Hernandez also has several industrial innovation and partnership grants which focus on energy recovery and sustainability aspects of wastewater treatment, both industrial and domestic.
Dr. Ryan is an environmental chemist whose research has focused on characterizing wastewater from mine drainage and mining activities, contaminated groundwater, biogeochemistry of metals transformations and contaminants from hydraulic fracturing fluids. Most recently he was the PI on a $12M NSF funded AirWaterGas network evaluating sustainability of the oil and gas operations in the Rocky Mountains.
The research conducted at the Rosario group deals primarily with environmental chemistry and oxidative processes (e.g., ozone) during water, wastewater and reuse treatment. The characterization of organic matter in the environment, natural and treated wastewater effluents, especially with optical properties is a focus. Ongoing research topics include environmental photochemistry of algal toxins and impact of wildfires on water quality and treatment.
The Cook Research Group specializes in the design and development of sustainable water treatment and resource recovery technologies. My group uses experimentation, process modeling, field work, and life cycle analyses to investigate three main research areas: sustainable water system design, water treatment and reuse, and material and energy recovery from waste. Her current research projects include sanitation in developing communities, drinking water system sustainability, water reuse and resource recovery, biochar as adsorbent and energy source and living hybrid materials.
Dr. Kasprzyk focuses on multi-objective decision making and model diagnostics for engineering problems in the areas of water resources planning and management, environmental engineering applications, and advancing methodological contributions to decision making and optimization under uncertainty. Current and recent projects include robust decision making for the Colorado River Basin; improving understanding of the relationship between water allocations and thermoelectric power generation; decision support for water treatment under climate extremes and multi-objective optimization for Front Range Colorado water planning.

Dr. Straub has experience developing materials, processes, and theoretical frameworks to improve the efficiency and cost of seawater desalination. He has specifically worked on analyzing the energy efficiency of membrane-based and thermal seawater desalination processes and has extensive experience developing novel membrane materials that can remove contaminants present in seawater. He has also been developing and analyzing high recovery membrane-based processes for inland desalination. These processes can reduce brine waste associated with brackish groundwater desalination. Specific projects have involved theoretical energy analysis and process testing for reverse osmosis and nanofiltration systems.
Dr. Mansfeldt’s research focuses on microbiologically mediated material biotransformations in municipal, agricultural, and natural environments. Within agricultural systems, his research focuses on the fate and recapture of aqueous nitrogen and phosphorus compounds, the origin, biotransformation, and legacy of polar trace organic contaminants such as pesticides, and the resiliency of the associated microbial communities to determine the appropriate treatment and application of the runoff. Concerning livestock applications, he also investigates bioindicators of pathogenic or waste-associated bacteria to track the quality of the water in receiving stream network.
Dr. Pellegrino's research revolves around fundamental membrane development, characterization, and applications. We study how the properties of both the membrane, the streams, and the choice of operating conditions control the separations and productivity results. Illustrative examples include: development of membrane-based devices as part of renewable energy-based heating and cooling systems; the use of membranes for product recovery and recycling water in algae and lignocellulosic biomass processes; and devising models for optimizing particle fractionation using membranes. Recent work includes the study and scale-up of membranes containing regular surface patterns produced with nanoscale dimensions. Currently we are incorporating these materials in studies of crystallization related to water desalination and making nanoparticles.
