Per <br />American Water Works Association standards, water towers should be washed out and <br />inspected at least once every three years. This process involves draining the tank, <br />removing debris and sediment, and scrubbing the interior. The tower has been <br />disinfected, refilled, bacteria tested and returned to service. The tower’s exterior was <br />completely pressure-washed as well (see attached photos). <br />• Road repairs have been completed for the water main break repair on Polk Street and <br />the water service leak repair on Business Center Drive. <br />• Water Quality Report clarification regarding the “Range” column in the regulated <br />substances chart in the report. The range column reflects the results of testing <br />performed, not a range of allowable limits. ERMU’s results fall well below the EPA limits <br />shown in the MCL (Maximum Contaminant Level) and MCLG (Maximum Contaminant <br />Level Goal) columns. MCLGs are non-enforceable public health goals, while MCLs are <br />legally enforceable limits for contaminants in drinking water. <br />• Eric Plude started on June 12 as a water department seasonal employee and will assist <br />with fire hydrant maintenance, water main valve exercising, and GIS mapping of water <br />system infrastructure. <br />88
