USDA-ARS Monitoring Water Quality Using Drones

USDA scientists are conducting research near Chesapeake Bay, Maryland, to test for E. coli in irrigation water using drones equipped with multispectral cameras. This technology helps identify potential crop contamination areas, aiming to provide farmers with a simple and affordable method to ensure water quality. The research, led by Yakov Pachepsky, involves sampling at various depths and locations. Future advancements may allow drones to collect water samples, saving time and money while enhancing food safety. The goal is to make compliance easier for farmers without adding strain.
