Details: SUMMARY: Contact Tracer Study DETAILS: The City owns and operates surface water system that provides treated water for domestic purposes to a full time population of 1,680 people through 800 connections. The source for the City’s water is an intake on Panther Creek. The treatment plant is a pressure filtration system. HBH received an assistance request from Mr Burham for the completion of a contact tracer study. I visited the water treatment plant to determine the methodology for the contact tracer testing. I preformed preliminary data collection at the determined flow rate. It was determined that the data collection did not produce a definitive result. Additional control measures were discussed for the next testing date. ACTION NEEDED: Perform additional data collection and complete tracer study.
