Details:	Robert Tilton notified the Circuit Rider that the City of Riddle needed a tracer study. 10-30-2018 – Jared Sylvester conducted a site visit and collected the information needed to put together the methodology for the tracer study. Through contact with OHA representative Jay Macpherson and the WD, it was determined the lack of separate chlorine dosing could present an issue during testing. Due to required use of perchlorinating during the rainy season and lack of separate dosing for perchlorinating and disinfection, either modifications would need to be made to allow for separate dosing capability, or the WD would wait until summer when perchlorinating would not be needed. The water district chose to wait for better water quality and reschedule. Follow-up this summer once water quality has improved been to perform CT study.
