| Details: | SUMMARY: Contact Tracer Study – Peak Flow Estimation DETAILS: The Hopewell Water Company owns and operates a groundwater system which is located just north of Salem. The water company has 45 connections and an approximate population of 100. The system is a rural system with significant lengths of small diameter pipe. The primary source for the system is Nelson Spring. The Circuit Rider was contacted by the water system because they are on a boil notice due to e. Coli positives in the spring water. It is a requirement that the system show adequate inactivation through disinfection. An attempt was made to determine contact time in the pipe to the first user, which would allow for the boil notice to be lifted. Following input from DWS staff, performed additional analysis of peak flows. Met with water system staff to test peak possible flow at first user, based on hydraulic limitations. ACTION NEEDED: Complete methodology and perform tracer testing on the system. | ||
