How Pure is Our Rainwater?  Project Harvest Results Postponed

Webinar Overview: In a great example of ‘citizen science’, Dr Ramirez-Andreotta and her team  conducted a three-year research project to learn about and practice rainwater harvesting to irrigate home and community gardens in Arizona, called Project Harvest. While the benefits of harvesting rainwater are recognized, there is a lack of information regarding the quality of harvested water and there are no monitoring programs. Citizen scientists collected environmental samples from residential, school, and/or community gardens irrigated by harvested rainwater to monitor the quality of harvested rainwater, soil, and plants between 2017-2020. Together, Dr Ramirez and citizen scientists generated a dataset to inform guidelines and recommendations for safe, harvested rainwater use on gardens and support communities to safely and sustainably produce their own foods using harvested rainwater.  
Speakers:. Mónica Ramírez-Andreotta is a community-engaged environmental health scientist and assistant professor of Environmental Science at the University of Arizona. Ramírez-Andreotta’s laboratory uses an environmental justice framework to investigate the fate and transport of pollutants in environmental systems, exposure pathways, cultural models of communication, and methods to improve environmental health literacy. As such, she is often found listening to and training communities and hosting community gatherings and data sharing events. Miriam Jones is a community health worker and is trained as an English-Spanish interpreter. She engaged with organizations, families, and individuals interested in becoming Citizen scientists through the Project Harvest in the Globe-Miami area.
