This slide presentation outlines a study on the relative human health risks associated with using chlorite ion to control nitrification. The presentation begins by outlining background information on nitrification, nitrate production, water quality problems from nitrification, chlorite ion control of nitrification, and studies of nitrification control using chlorite ion across the United States. Risk definitions are given along with risks associated with the use of chlorite, risks associated with nitrification and other control methods, risks associated with HPC and opportunistic pathogens, risks associated with pH depression, and relative risk comparison. Includes tables, figures.
