Having recently published an article in AWWA Water Science, Giridhar Upadhyaya answered questions from the publication's editor-in-chief, Kenneth L. Mercer, about the research. Resilient Biological Hexavalent Chromium Removal With a Two-Stage, Fixed-Bed Biotreatment System Giridhar Upadhyaya, Brandon Dunagan, Chris Mattingly, and Jess Brown I am from Nepal, which I believe is the most beautiful country in the world. Though the country is rich in water resources, it has challenges typically faced in underdeveloped countries, the most critical of which is limited public access to safe and reliable drinking water sources. Contamination of local surface and groundwater sources by pollutants, such as nitrate and arsenic, further aggravates the situation. While working as an engineer for the government of Nepal, I had opportunities to experience and understand the difficulties rural communities face just to get a bucket of drinking water. I was devastated that so many people contracted diseases from chronic exposure to arsenic and other contaminants. Even worse, they had no alternatives.

I am a fortunate member of the Carollo Research Group, which consists of world-class scientists, engineers, and technologists. As a consulting firm that focuses solely on water, Carollo's research includes water and wastewater treatment, potable reuse, stormwater and graywater management, and industrial water. In the past 10 years, we've completed 270 bench-, pilot-, and full-scale research and development projects that have investigated a wide variety of topics, including potable reuse, biological treatment, distribution system corrosion and water quality, intelligent water systems, nutrient removal, desalination and concentrate management, and emerging contaminants, such as per- and polyfluoroalkyl substances, algal toxins, endocrine-disrupting chemicals, and pharmaceuticals. We are one of the pioneers of the “One Water” concept, which has been central to our recent research efforts. We were recently awarded and are now working on The Water Research Foundation's Project 5049, Public Health Benefits and Challenges for Blending of Advanced Treated Water With Raw Water Upstream of a Surface Water Treatment Plant, the latest addition to Carollo's efforts in pursuing One Water. Through this important project, we are collaborating with multiple utility partners who lead the water reuse sector. It's time for a rest while hiking among boulders at Chautauqua Park in Boulder, Colo. Groundwater contamination with pollutants such as nitrate, arsenic, and hexavalent chromium is a widespread problem across the globe. However, water scarcity, climate change, and ever-increasing populations have forced policymakers, water resource managers, and utilities to find ways to safely use contaminated water sources. While physical–chemical technologies are available to treat these various contaminants, they generate concentrated waste streams and are often chemical- and energy-intensive. Biological processes provide alternative treatment approaches that minimize chemical and energy use without generating concentrated wastes. In many cases, biological treatment removes multiple contaminants—for example, nitrate and arsenic—in a single unit process, generating innocuous, less toxic, and easily separable end products, which, in this example, are N2 and arsenic containing iron hydroxide or iron sulfide solids. Fond of spending time in nature, Giridhar finds the view of a dormant volcano in Oregon captivating. I'm an avid fan of Mother Nature—I often go on hikes and am a frequent visitor to Nepal's many beautiful national parks. I'm particularly amazed by nature's ability to adapt; for example, this is reflected in how bacteria indigenous to certain water sources adjust to changing water quality conditions. Despite the unfortunate anthropogenic contamination of natural sources, local microorganisms have the ability to gradually adapt to new conditions, consuming contaminants as their food source and in turn cleaning the environment. While we must avoid damaging ecosystems by actively limiting and controlling contaminant release, I believe we can benefit greatly from continuously exploring opportunities that leverage environment-cleaning microorganisms in combination with physical–chemical processes. Engineering translates intensive research work into practical and efficient technological solutions that ultimately minimize health risks. However, a disconnect is often observed between scientific innovation and its implementation when the target beneficiaries’ specific economic status, objectives, needs, and limitations are not adequately assessed. The focus of future scientific and technological advancements must be placed on understanding and meeting end users’ requirements during all phases of technological development and implementation. Our article reported the effectiveness and efficiency of two-stage, fixed-bed biological treatment in removing hexavalent chromium from contaminated groundwater. This work helps expand the menu of hexavalent chromium treatment options that regulators may consider when establishing contaminant limits and utilities may consider when developing management and treatment strategies. I grew up in a musically rich society, watching my relatives and friends enjoy and play musical instruments in our homes. Despite my sincere desire to learn instruments of my Eastern culture, I did not get opportunities to extensively explore them during my childhood. In the past couple of years, I've returned to this interest and have begun exploring various instruments, including the drums and the harmonica. Teaching myself to play these instruments has been challenging but also incredibly mentally relaxing. Music provides a much-needed creative outlet, which I can share with my family and friends. By using song and music to stay connected with myself and my community, I maintain that much-desired work–life balance.
