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, an 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.

Gardening & Health Survey 

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 are 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.

• Our survey on gardening and outdoor activities as stress management techniques was highlighted in the Maryland Today article "Digging Into Gardening Trends" on September 3, 2020.
• An article exploring farmers' preferences for education and outreach related to nontraditional water use was published in JEMA.
• On December 4, 2019 we held the first in a series of Maryland grower water reuse workshops.  The Maryland Independent news outlet published an article about the successful workshop titled "Farmers, ag experts explore opportunities for reclaimed water."
• The RRIPER project was selected as a recipient of the Interdisciplinary Projects for Community Resilience in Urban and Peri-urban Environments Seed Grant from the College of Agriculture and Natural Resources Strategic Initiative  Implementation Team: Optimize Urban Environments Through Design, Green Technology and Community Engagement.
