Full Description

This article discusses a project which was jointly funded by the American Water Works Association Research Foundation (AWWARF) and the Electric Power Research Institute/Community Environmental Center. The goal of this project was to assess whether a particular electrotechnology device was capable of inactivating Cryptosporidium parvum oocysts. Inactivation was measured by a variety of in vitro techniques and animal infectivity using the neonatal mouse assay. The in vitro techniques were used initially to determine if reduction in viability occurred; animal studies were done only on those electrotechnologies that were capable of reducing viability of Cryptosporidium to establish oocyst inactivation. The research demonstrated that nonconventional applications of UV light are capable of inactivating C. parvum in water treatment systems. Further results are discussed. Includes 25 references, tables, figures.
