Project Grant 2550355

Federal Grant Award Summary

The University of Florida received a $200,000 Project Grant from the National Science Foundation's Division of Chemical, Bioengineering, Environmental, and Transport Systems (Engineering program, CFDA 47.041) effective May 1, 2026, through April 30, 2029. This collaborative research initiative will develop a mechanistic and predictive framework that links microscale biofilm-pipe interface processes to disinfectant decay rates and localized corrosion in drinking water distribution systems. The primary deliverables include high-resolution experimental data from controlled biofilm reactors containing ductile iron, copper, galvanic joints, and inert control materials, combined with artificial intelligence (AI) tools to create predictive models. These products will enable water utilities to estimate chlorine demand more accurately, optimize disinfectant contact time, and improve corrosion control in compliance with regulatory standards such as the Lead and Copper Rule Improvements.

The project will also generate mechanistic understanding of how disinfectants, corrosion inhibitors, and microorganisms interact at the pipe-water surface on a microscopic level—knowledge that bulk water property measurements cannot currently provide. Complementary deliverables include workforce development through training of students in environmental engineering, biotechnology, electrochemistry, and artificial intelligence, as well as strengthened collaboration frameworks between research institutions and water utility partners. These outputs will support water quality management practices and contribute to protecting public health through safer, more reliable drinking water supplies.
