The process will proceed over a couple of months this summer and will greatly increase our effectiveness during filtration. • The Minnesota Department of Health(MDH) completed their routine sanitary survey on May 21, 2015. There were a few recommendations for improvement noted by the MDH Engineer. The recommendations noted have already been rectified by the water operators and will not be an issue in the future.

Our wells have been tested in the past for radium-226,radium-228, and gross alpha in water and are under the maximum contaminant level of 5.4 pc/1 total for radium-226 and radium-228 and under 15 pc/1 for gross alpha. • We applied for a fluoride variance to Minnesota Rule 4720.0030 and it was approved.
