The NSPF is also funding work to understand and define the chemistry of disinfection byproduct (DBP) formation in chlorinated, indoor pools. Ernest Blatchley III, Ph.D., P.E., BCEE, Purdue University, was awarded a grant of $75,000 as the first step in a three-year program to research combined UV and chlorine swimming pool water disinfection methods. The research will examine the effects of combined treatment on water and air chemistry in chlorinated, indoor pool settings. The grant, managed and administered under the NSPF industrial research grants category, includes donations from the Research Foundation for Health and Environmental Effects and one leading UV manufacturer, Engineered Treatment Systems LLC. The goal of this work is to give industry, regulators, facility operators and management a better understanding of swimming pool disinfection byproduct chemistry and technology options for their control, including Cryptosporidium inactivation. In turn this information will be helpful in reducing human exposure to DBPs in recreational water facilities. Questions about this project should be directed to Professor Blatchley (blatch@purdue.edu).
