| Details: | SUMMARY: Contact Tracer Study DETAILS: The City owns and operates a Surface Water system, which supplies approximately 5800 people through 2000 connections. The city treats water from multiple creek sources. In addition, water is provided through 2 wells. HBH was contacted by the city to provide assistance with a contact tracer study. When discussing the study, it was determined that a hydraulic connection at the surface water treatment plant would potentially interfere with the testing. I discussed causes and a remedy for the hydraulic problem, which appears to be an air lock in an artificial high point in the WTP piping. ACTION NEEDED: I performed CT testing and the city also has requested assistance with filter optimization. | ||
