Staff contacted residents to ask if they would participate, delivered <br /> sample bottles with instructions to those who agreed, picked up the water samples, and <br /> sent them into a lab to be tested.The results will be sent to the Minnesota Department <br /> of Health (MDH) and each resident that participated. <br /> • Repairs needed resulting from the backwash flooding at the Well 6 Water Filter Plant <br /> have been completed. That well is back in operation. <br /> • Short Elliott Hendrickson Inc. performed an inspection of the paint inside of the tank of <br /> Gary Street Water Tower; the report will be used for obtaining bids for repainting the <br /> tank interior. <br /> • On June 23, at Well 4 Water Filter Plant, a pipe elbow cracked close to the chlorine <br /> injection point and started leaking chlorine-rich water. The water did not contact <br /> anything but chlorine gas levels were elevated inside the plant. Contractors came out <br /> the following week to look at issues with the alarm system and well controller; they <br /> found that the issues were probably not due to corrosion from the short exposure to <br /> increased levels of chlorine gas. <br /> • The water operators have been performing hydrant flow tests to collect water flow data <br /> across the water system. <br /> ATTACHMENTS: <br /> • June 2019 Pumping by Well <br /> Page 1 of 1 <br /> 124 <br />
