All Sources To Do Public Notice Yes No N/A List We discussed the requirement for immediate public notice of an E. coli-present source sample result with our water system’s governing body (board of directors or commissioners) and received direction from them on our response plan. We discussed the requirement for immediate public notice of an E. coli-present source sample result with our wholesale customers and encouraged them to develop a response plan. We have prepared templates and a communications plan that will help us quickly distribute our messages. E. coli-Present Triggered Source Sample Response Checklist Source S01 – To Do Alternate Sources Yes No N/A List We can stop using this source and still provide reliable water service to our customers. We have an emergency intertie with a neighboring water system that we can use until corrective action is complete (perhaps for several months). We can provide bottled water to all or part of our distribution system for an indefinite period. We can quickly replace our existing source of supply with a more protected new source of supply. To Do Temporary Treatment Yes No N/A List This source is continuously chlorinated, and our existing facilities can provide 4-log virus treatment (CT = 6) before the first customer. If yes, at what concentration? ___ mg/L We can quickly introduce chlorine into the water system and take advantage of the existing contact time to provide 4-log virus treatment to a large portion of the distribution system. We can reduce the production capacity of our or alter the configuration of our storage quantities (Operational Storage) to increase the amount of time the water stays in the system before the first customer to achieve CT = 6. We can alter the demand for drinking water (Maximum Day or Peak Hour) through conservation messages to increase the time the water is in the system prior to the first customer in order to achieve 4-log virus treatment with chlorine.
