Water System Improvements

City of New Germany, Minnesota

The City of New Germany's wells had levels of radium in excess of the Maximum Contaminant Level (MCL) in addition to iron and manganese concentrations above the Secondary Drinking Water Standards. The city also had no treatment other than chemical addition of fluoride, phosphate, and chlorine.

Bolton & Menk performed a water study to review options for removing radium from the city's drinking water. The proposed project consisted of a new aluminum gravity filter to remove the radium, iron, and manganese. A pilot study was conducted to confirm that the radium would be removed by filtration as part of the pre-design. A new masonry building was constructed to house the filter and equipment. Backwash holding tanks were included to allow slow release of backwash waste to the sanitary sewer system. The facility has a treatment capacity of 125 gpm. The facility is now providing safe drinking water for the city to use.
