Full Description

Through the assessment of vulnerabilities to drinking water systems, water security experts haveidentified the distribution system as one of the most vulnerable components in a drinking water utilitywith respect to contamination; thus, the distribution system is the primary focus of contamination warningsystems. To address the risk of drinking water contamination, the Homeland Security Presidential Directive 9 requires the U.S. Environmental Protection Agency (USEPA) to develop and implement acontamination warning system for drinking water (US Office of the President, 2004). This directive gaverise to the USEPA's Water Security initiative (WSi), (formerly known as WaterSentinel).In order to demonstrate the WSi contamination warning system design, the USEPA is partnering with drinkingwater utilities to deploy pilots. The first of these pilots was launched in Cincinnati, in partnership withthe Greater Cincinnati Water Works (GCWW) and other local agencies. This pilot was launched in early2006, and achieved operational status at the start of 2008. As part of the contamination warning system pilot, two early detection sensor (EDS) tools were deployed at GCWW. Theobjective of this paper was to summarize the first year of experience with water quality event detection atthe Cincinnati contamination warning system pilot. This paper describes the water quality monitoringsystem deployed at GCWW, discusses the performance of water quality EDS tools, and shares lessonslearned from alarm investigations. Includes 9 references, table, figures.
