Chloraminated Distribution System Field Event

During the week of May 12th, members of the Optimization Team, in partnership with Pennsylvania Department of Environmental Protection’s (DEP) and Allegheny County Health Department (ACHD), conducted the first field event to support the development of a Distribution System Comprehensive Performance Evaluation (DS CPE) for chloraminated water systems. The DS CPE protocol was originally developed for water systems that use free chlorine as a secondary disinfectant. As a result, the existing DS CPE is in the process of being adapted to apply to chloraminated water systems. The field event provided an opportunity to field test aspects of the
DS CPE that were recently modified (e.g., additional monitoring parameters) or added (e.g., evaluation of chlorine and ammonia practices) to apply to chloraminated water systems. The event also provided an opportunity to assess the system’s performance relative to the proposed goals for chloraminated water systems. The host system, Oakmont Water Authority, welcomed the feedback from the team during the exit meeting and TSC will request updates on their pursuit of optimization from DEP and the ACHD staff.
