UWIN Citizen Science Project

Off the Roof

What’s in Your Rain Barrel?

Sybil Sharvelle, PhD

Colorado State University

 

Given the recent, tragic events such as the lead poisoning of Flint residents or Cape Town running out of water many homeowners have begun using rain barrels to collect rainwater falling on their property.  This harvested rainwater, also known as “roof runoff”, is commonly used for irrigation of lawns, landscaping, garden beds or indoor plants, decreasing the demand from local drinking water supplies.

However, little is known about the microbial quality of the water or potential pathogens capturRain barreled in roof runoff.  UWIN is undertaking a new citizen science project to understand more about harvested rainwater.

Off the Roof is a citizen science project developed to provide data to UWIN researchers to better understand what pathogens may reside in roof runoff collected in rain barrels. “We’ve realized a real limitation in the use of roof runoff as an alternative water source in urban areas is the lack of data on the microbial quality of the water,” says Dr. Sybil Sharvelle, the project’s primary investigator and lead of UWIN Project B1-1b which examines use of alternative water sources. “This results in ambiguous regulatory guidelines for how the water needs to be treated for various end uses.”

Participants in Off the Roof will install rain barrels to their downspouts to collect water from precipitation events at three different times of year and submit samples to the EPA for microbial examination.

Dr. Sharvelle has nine years of experience working on graywater projects. Her graduate studies were funded by NASA to optimize biological waste processing systems that would treat graywater with the end goal of potable reuse. The waste treatment concept employed entailed separate source collection and treatment of graywater, urine, and fecal material. Dr. Sharvelle’s experience in closed loop recycling of resources is very valuable for implementation of sustainable development concepts for urban water management. Dr. Sharvelle is currently working on sustainable urban water management including graywater reuse, reclaimed water reuse, development of models to estimate water savings associated with urban water conservation practices. Dr. Sharvelle also has several years of experience working on waste conversion to methane through anaerobic digestion.

Jay Garland

Division Director, National Exposure Research Laboratory

Area of Expertise: Dr. Garland worked for over 20 years on NASA’s efforts to develop regenerative, closed-loop life support systems, including testing of recycling systems based on plants and microorganisms, before joining EPA’s Office of Research and Development in 2011. He has authored over 100 scientific papers on various topics, including methods for microbial community analysis, the ecology of plant-associated microorganisms and the recycling of solid and liquid wastes in plant growth systems. His work is committed to the development of sustainable systems using sound ecological principles and innovative technology

 

Nichole Brinkman

Biologist, National Exposure Research Laboratory

Area of Expertise: My current research focuses on two major topic areas. The first research area involves describing and evaluating the microbial communities in our aquatic resources through EPA’s nationwide surveys. This research will facilitate understanding of the microbial processes in our watersheds and could aid in assessing water quality, aquatic condition and watershed integrity. My other research area is centered on the practice of decentralized, on-site water reuse for non-potable purposes. This work aims to evaluate pathogen densities in a variety of operational systems to provide data to better inform quantitative microbial risk assessment models and allow policy makers to institute practical, but safe treatment requirements for on-site systems. In addition, fast and reliable monitoring of recycled water is being investigated through the use of real-time, online water quality sensors and by investigating the microbial communities in on-site systems to identify abundant members that could be used as

Rutgers University

Dr. Rebecca Jordan received her M.Sc. and Ph.D. in Organismic and Evolutionary Biology at the University of Massachusetts Amherst under the advisement of Francis Juanes. Her dissertation research investigated the visually guided mating behavior of Lake Malawi cichlid fish. Rebecca took a post-doctoral position as a Science and Technology Council Fellow with James Gould at Princeton University. There she expanded her interests to animal learning in general and incorporated work with undergraduate science learning. After two years at Princeton, Rebecca took a Visiting Assistant Professor position at Elizabeth City State University as part of a partnership with the University of North Carolina at Chapel Hill. In Elizabeth City, Rebecca continued her work with fishes in the capacity of providing undergraduates with research experience. She focused mainly on poeciliids. Also in Elizabeth City, Rebecca broadened her study of science learning to incorporate informal audiences. Rebecca is currently an Associate Professor of Environmental Education and Citizen Science in the Departments of Ecology, Evolution, and Natural Resources and Human Ecology at Rutgers University New Brunswick.

Robert Dunn

North Carolina State University

Most of the living world remains poorly or totally unknown. In my lab we study the species around us in our everyday lives, species we tend to think of us as well known. Most of those species are not well known and so there are many things to discover in your backyard, in your bedroom, or even on your roommate. Some days I work to study these species myself, bending down to figure out whether the fungus on my neighbor’s foot is a new species. More often I spent my time working with students and other researchers to help along their own discoveries. I also write about the world around us, which is a chance to share the stories of the scientists who have devoted their lives to understanding species, organs, cells, genes or ecosystems that influence us every day. In my building alone I am surrounded by biologists who study prairie voles, rare butterflies, fish ovaries, dinosaurs with long, long, claws, the decisions we make when threatened with death, alcoholic fruitflies, fungus farming beetles, and much, much more. It is a good job, this thing called science, silly at times, serious at others, but nearly always good.
