Water Source The seal around the pump base at Well No. 1 should be repaired. The static and drawdown should be checked and recorded monthly. Pumps/Pump Facilities and Controls A new sample tap should be installed at Well No. 2. Treatment All containers holding hydrofluosilicic acid should be sealed as air-tight as possible and vented to the outside atmosphere to minimize the effects of the acid fumes. AR chemical vents must be equipped with non-corrodible insect screens. All threaded hose bibbs must be equipped with approved vacuum breakers. Since chlorine has not been fed for several years, the chlorine cylinders should either be removed from the chemical room at Well No. 1 or the following repairs must be made: a. The air intake shall be moved to the ceiling and away from the exhaust vent. b. An inspection window between the pump room and chemical room shall be installed. Switches for the lights and fan should be located at the inspection window. c. The exhaust fan must be able provide one air exchange per minute. Water Storage No deficiencies reported.

Surveyor: CerirairTh System Contact:Tom Ozzello Surveyor Signature: ti The findings below identify sanitary risks that may impact water quality, inform the water supply owner of applicable responsibilities, and/or provide guidance related to water system operation and maintenance. Water System Management/Operation The City should consider useing the permanent chlorination equipment and maintaining a free chlorine residual of at least 0.2 to 0.5 milligrams per liter on all points of the distribution system. A daily check of critical system components should be conducted to enhance security and ensure that an unauthorized entry has not taken place. Operator Compliance with State Requirements The opportunity for additional training in water supply work should be made available to the operator(s). Attendance at the annual waterworks operators seminar, held in the area, is a valuable experience for anyone engaged in this field.
