Description
The focus of this paper is on mitigating the potential risks posed by the recycling of Cryptosporidium and other disinfection resistant pathogens for the following reasons: recycle flows can contain high concentrations of Cryptosporidium and may degrade finished water quality; standard disinfection practice, an important component of the multibarrier protection provided by treatment plants, might not be effective against Cryptosporidium and the other disinfection resistant pathogens; and, recycle practice may contribute to the occurrence of cryptosporidiosis and other microbial diseases. This paper discusses the following activities in developing regulatory requirements to govern recycle practice: develop a baseline of current national recycle practice and use it to assess the costs and benefits of regulatory options; characterize the occurrence of pathogens in recycle water and the potential risk these contaminants pose to finished water quality under various recycle schemes; evaluate regulatory options for minimizing potential risks posed by recycle; and identify additional information needed to develop the regulation.
