This research evaluates hydroponic farming as a sustainable food production strategy. By combining interviews, environmental modeling, and economic simulations, it compares hydroponic and conventional agriculture, finding reduced water use but higher energy demands. The work identifies conditions under which hydroponics can support farmers, communities, and environmental goals.

Urban farms in Baltimore need reliable irrigation water. This research tested harvested rainwater for E. coli, Listeria, and Salmonella, and evaluated two treatments: sand–iron filtration and peracetic acid sanitizing. Both reduced E. coli, and sanitizing eliminated Listeria. Produce remained contamination-free, suggesting treated rainwater is a viable supplemental irrigation source.
