| Details: | SUMMARY: Contact Time Tracer Study DETAILS: System owns and operates a ground water system that provides water to 125 people through 125 connections. The water source for the system is a single well. Water is treated by an ion exchange system prior to disinfection with sodium hypochlorite. Due to the need for the water system to provide 4-log inactivation of viruses (Groundwater Rule-GWR), it was requested that HBH assist the system by performing a Contact Tracer Study. I visited system to set up tracer study. ACTION NEEDED: Determine proper methodology for the Ct Study and perform the study. | ||
