Bench-Scale Methods to Investigate Release of Legionella in Biocorrosive Environments

The purpose of the proposed research project is to develop a bench-scale method to investigate the release of opportunistic pathogens such as Legionella pneumophila, in drinking water distribution systems. Legionella pneumophila can cause serious health effects in humans and causes one of the largest water related diseases. To complete this research, two bench-scale experiments have been designed to simulate a drinking water distribution system. Small flow-through reactors containing copper, lead and cast iron coupons will be used to investigate the affects that different chemical disinfectants and corrosion inhibitors have on the growth and release of Legionella. The expected outcomes of this project are to provide water utilities with recommendations of disinfectants and corrosion inhibitors to use based on their piping materials, and to create opportunity for more research in this field to prevent the release of Legionella into drinking water systems.
