Real‐time detection of intentional chemical contamination in the distribution system
The first casualties after an intentional contamination event are currently identified by physicians or other health care providers because the onset of symptoms occurs well after exposure. One approach to mitigating this potential disaster includes online monitoring of drinking water distribution systems. Four credible‐threat drinking water contaminants (aldicarb, sodium arsenate, sodium cyanide, and sodium fluoroacetate) were added to tap water and analyzed at different concentrations to determine their detectability in a distribution system. Bench‐top analysis and online monitoring equipment were used to measure pH, chlorine residual, turbidity, and total organic carbon values before and after introduction of these contaminants. Results indicate that all four contaminants can be detected at relatively low concentrations. Three of the four contaminants were detected below a concentration that would cause significant health effects.
