Current Projects:
The Water Emergency Team
Exposure to raw sewage from failing infrastructure can lead to negative health outcomes, distress, and feelings of disenfranchisement, particularly in marginalized urban communities. Sanitary sewer overflows (SSOs), the release of untreated sewage from a municipal sewer system, affect several cities around the world, with as many as 75,000 occurring each year in the U.S. Baltimore experiences frequent SSOs and household basement backups due to aging and failing sewer and stormwater infrastructure. As a result, communities are persistently exposed to raw sewage, likely containing waterborne pathogens and possibly antibiotic-resistant (AR) bacteria. While AR bacteria have been identified in wastewater at wastewater treatment plants, no studies have comprehensively evaluated exposure to these pathogens from SSOs or backups, nor the impact of physical damage to the home and infrastructure on communities. This project addresses these knowledge gaps by proposing to develop a community-driven rapid response Water Emergency Team (WET) to respond to SSOs and backups in underserved African American communities in Baltimore and the surrounding region. WET will complete visual household inspections, conduct residential surveys and interviews about impacts and experiences with these events, collect water and surface swab samples from impacted indoor areas, and analyze samples for AR bacteria, reporting results back to the community. WET will work directly with community organizations and neighborhood associations throughout the project, including translating our research findings into an outreach program with the goal of empowering affected communities and informing local policymakers. Climate change will only continue to stress the U.S.’s crumbling infrastructure, disproportionately impacting marginalized communities exposed to raw sewage. Our team has the expertise, experience, and community partnerships to address these issues, bringing national attention and visibility for the university and communities alike.

Global FEWture Alliance
Climate change, population growth, and urbanization are crippling global food, energy, and water (FEW) systems and harming public health, with low-income communities and people of color bearing the heaviest burdens. There are 1.3 billion people worldwide who are food insecure, 2 billion people who lack access to safe drinking water, and 770 million people who lack access to electricity. These challenges will only grow worse over the next 30 years. To date, solutions addressing these pervasive challenges have often been siloed and inequitable. Initiatives tend to focus on food production, access to water or access to energy technologies, but often fail to take into consideration all three vital resources along with the required capacity building and educational programs necessary to sustain interventions. The Global FEWture Alliance—a UMD-based international alliance—will scale technology-based solutions, community-driven capacity building, and experiential education focused at the food-energy-water-climate-health nexus. Through our holistic, interdisciplinary, systems-based approach, we will alleviate food and water insecurity, protect environmental and global public health, and bolster community resilience in a changing climate. Our integrated, multi-sectoral approach will result in solutions, from local to global scales, that address at least 13 of the 17 United Nations Sustainable Development Goals. Here at UMD, the Global FEWture Alliance will advance all four strategic commitments of the new Strategic Plan: taking on humanity’s grand challenges, investing in people and communities, partnering to advance the common good, and reimagining learning.

Septic to Sewer?: Justice-focused strategies for addressing coastal septic failures under sea-level rise and increased flooding
As rising sea levels increasingly strain septic tank systems used by tens of thousands of Maryland households, a new $1.35 million grant from the U.S. Environmental Protection Agency (EPA) will fund a University of Maryland-led team’s investigation of ways to head off a looming sanitation crisis that could disproportionately harm the state’s Black residents. The multi-institutional project headed by civil and environmental engineering Assistant Professor Allison Reilly includes several other UMD researchers in addition to partners at George Mason University and nonprofits focused on natural resources and environmental justice. UMD team members include biofilms expert Birthe Kjellerup, associate professor of environmental engineering and the A. James Clark School of Engineering’s diversity, equity and inclusion committee chair; Rachel Goldstein, assistant professor in the School of Public Health’s Maryland Institute for Applied Environmental Health; and Andrew Lazur, a water quality specialist with the College of Agriculture and Natural Resources. George Mason coastal hydrologist Celso Ferreira and economists Yanjun “Penny” Liao and Margaret Walls from Resources for the Future, a D.C.-based research institution, round out the team. Each will apply their specific domain of expertise to the interdisciplinary problem; Ferreira, for instance, will examine flooding patterns and how they are likely to evolve over time, while Goldstein will study the particular health risks posed by failing septic systems. The team is also partnering with Southeast Rural Community Assistance Project (SERCAP), which works with lower-income local homeowners to address problems with their homes, including repairing failing septic systems. Jean Holloway, Maryland and Delaware state manager, will represent SERCAP on the project.

RRIPER (Rooftop Runoff Irrigation Produce Eaten Raw)
The RRIPER (Rooftop Runoff Irrigation Produce Eaten Raw) program led by Dr. Rachel E. Rosenberg Goldstein in the Maryland Institute of Applied Environmental Health, School of Public Health, University of Maryland seeks to evaluate the quality of harvested rainwater and rooftop runoff used to irrigate produce. Using alternative water sources is increasingly important as we face a global water crisis. It is crucial that every drop of water be used wisely, including water that falls as rain or runs off our roofs. Despite the abundance of rainwater barrels in use in Maryland, gardeners have previously been advised against using harvested rainwater or rooftop runoff to irrigate gardens because of water quality and food safety concerns. However, studies on the microbial and chemical quality of harvested rainwater or rooftop runoff are limited and contradictory.
During the summers of 2018 and 2019, the RRIPER program analyzed rooftop runoff, soil, and produce grown with rooftop runoff for bacterial indicators (total coliforms and E. coli), pathogens (Salmonella and Listeria monocytogenes), and heavy metals (aluminum, cadmium, copper, lead, and zinc) in vegetable raised garden beds using a subsurface irrigation system supplied by rooftop runoff in Frederick, Maryland. While the water quality data of the garden beds at the coalition is still being analyzed, prior research has shown that community gardens with stormwater management systems can increase community wellbeing and protect environmental resources (Tom et al., 2013). The Frederick garden site has shown social benefits of harvesting stormwater runoff, including community engagement and improved access to fresh produce. More detailed information on the Frederick raised vegetable garden beds can be found in the University of Maryland Extension fact sheet “Watering Seeds of Change with Rainwater”. We plan to continue our work to evaluate multiple types of rainwater and rooftop runoff harvesting systems to assess their safety for irrigating fresh produce.

CONSERVE
CONSERVE (COordinating NontraditionalSustainable watER Use in Variable climatEs): A Center of Excellence at the Nexus of Sustainable Water Reuse, Food, and Health’s mission is to facilitate the adoption of transformative on‐farm treatment solutions that enable the safe use of nontraditional irrigation water on food crops. Climate change and population growth are stressing our freshwater resources, requiring the exploration of alternative water sources, including reclaimed water (highly treated municipal wastewater). Finding reliable, safe irrigation water is especially important for farmers as agriculture is the largest water user worldwide and in the US. For water reuse in agriculture to be a viable option, buy-in from farmers is crucial.
As the co-Project Director of Extension for CONSERVE, Dr. Goldstein led a multi-region needs assessment survey among farmers on nontraditional water use opinions and communicated research results to growers, local and state regulators, and other interested parties through multimedia outreach and educational materials as well as through in-person workshops and community events. The CONSERVE Extension team is increasing understanding and acceptance of water reuse in agriculture among non-agricultural communities through outreach and education activities.

Moving Beyond the “Yuck Factor”: Measuring brain responses to water reuse terms and determining if natural environmental images change responses
Water reuse (the beneficial use of reclaimed water) is becoming increasingly necessary as climate change and population growth stress freshwater resources. While government agencies, scientists, and the water industry have recognized the importance of water reuse, a commonly cited barrier is consumers’ negative perceptions - the ‘yuck factor’. There is an urgent need to determine how to increase public acceptance of water reuse. Education could be instrumental for changing perceptions, but to date there has been a lack of outcome studies on the effectiveness of water reuse education.
This study’s goal is to improve acceptability of water reuse by determining if educational videos modulate perceptions of water reuse terms. We are measuring changes in neural activity in response to multiple categories of water reuse terms pre- and post-exposure to water reuse education videos using electroencephalogram (EEG). The results from this study can validate and increase the effectiveness of water reuse education materials using objective neurocognitive measures. The integration of psychology into water resource educational efforts will aid targeted education campaigns which will impact communication, acceptance, and policy.

RANG (Reducing Anxiety with Nature and Gardening)
The COVID-19 (coronavirus) pandemic and resulting stay-at-home orders have resulted in increased levels of anxiety and stress. There have been several news articles written about the increase in seed sales and the benefits of gardening, however there have been limited scientific studies about if gardening and reduced anxiety are significantly associated. We have developed a survey to determine the increase in gardening during the COVID-19 pandemic and if gardening is associated with reduced stress and anxiety. The results of this survey will be used by University of Maryland Extension (UME) educators in addressing and directing future educational programming and resource development for existing and beginning gardeners.
This survey is open to all individuals who are at least 18 years old and located in the United States. It is estimated that the survey will take 10 minutes or less to complete. The survey is anonymous and does not contain questions that may personally identify you. Please complete the survey only once. The survey will be open until June 1, 2021. Thank you for helping us identify ways to reduce stress and provide gardening information.

Healthy Garden, Healthy You
Mental health and food insecurity are two of the greatest public health challenges facing our nation. Gardening is a means to provide nutritious food, and a growing body of literature has identified the mental health benefits of gardening, including mood improvement, reduced anxiety, and trauma recovery. Racial and ethnic minority communities, including those in local Prince George's County and Baltimore City, MD are disproportionately impacted by poverty, mental health problems, and limited access to healthy food. Through this project we will create virtual toolkits, host a webinar, and develop fact sheets to share information with local, underserved urban communities about the mental and physical health benefits of gardening. Urban gardening will be further promoted by teaching community members how to start their own urban gardens and equipping them with garden starter kits.
