“…However, when using microorganisms as a tool for the measurement of the presence of toxics in water, those in biofilm (extracellular polymeric substance [EPS]) react to toxic compounds as the detached biofilm particles can be as equivalent as the measurement of turbidity in the water. The quality assurance (QA) of the collected data is utterly critical to the justification on the data analysis (Cho, 2013). When it comes to establishing an online monitoring methodology, eliminating a noise or background data is the key point to avoiding possible false positive results for the determined statistical analysis.…”

“…Studies and news stories have shown that current water distribution systems are vulnerable and overdue for a terror-type attack (Cho et al, 2013;Greenfield et al, 2002;Kroll and King, 2007). The threat of impending water system is real.…”

“…Because South Korea was the host of G20 (The Group of Twenty Finance Ministers and Central Bank Governors) for 2010 International Meeting in Seoul. Like mentioned in real-time cases, water terrorism through drinking water systems can undermine public health and environment, which will damage on societal functioning that may result in an economic collapse (Cho et al, 2013).…”

“…Some can be delivered in a microcapsule. For the chemical threats such as chemical warfare agents and industrial chemical poisons, chemical warfare agents can be hydrogen cyanide, tabun, sarin, soman, VX, lewisite, sulfur mustard, 3-quinucli dinyl bensilate, and lysergic acid diethylamide, while industrial chemicals can be arsenic, fluoride, cadmium, mercury, dieldrin, sodium fluoroacetate, parathion, aldicarb, cycloheximide, dicrotophos, nicotine, sodium arsenate, sodium cyanide, and sodium fluoroacetate (Mays, 2004;Cho, 2013). In this study, a group of major chemical contaminants were experimented, not including biological pathogens.…”

Since the tragic event on September 11, 2001 (9/11), homeland security has been the center of major attention not only in the United States but also around the world. Among homeland security agenda, more concerns on drinking water system have been drawn into the forefront attention from the public and water industry. Governmental agencies have been called upon to strongly protect the water resources from becoming a possible terror target. The online monitoring of a water system offers the potential to reduce the possible danger from a terrorist contamination as well as from unintentional chemical spills. As potential terrorist contaminants, seven chemical compounds (aldicarb, cycloheximide, dicrotophos, nicotine, sodium arsenate, sodium cyanide, and sodium fluoroacetate) were studied at different doses, in order to determine their detectability when they are present in a water system, including intake, treatment, and distribution. These contaminants were monitored by measuring simple water quality parameters such as conductivity, pH, chlorine residual, turbidity, total organic carbon (TOC), and UV254. Results indicated that the contaminants used for the study were detected at certain toxicity concentrations through the online water quality monitoring method. This method provides a useful tool for watching water resources against possible terror attacks, and also keeping safe water quality.

“…Protection of water distribution systems may include installation of early warning detectors, biosensors, security cameras, monitoring of pipe deterioration levels, etc. (Ostfeld and Salomons, ; Raciti et al., ; Amin et al., ; Cho et al., ). Mitigation policies focus on minimizing the consequences of disruptions.…”
