City starts planning for new well
Rosemount’s population is growing and so is its need for water. The city council on Tuesday approved the development of a new well.
City engineer Andy Brotzler said based on the number of additional units approved since Well 15 came online, it’s time for the city to start planning for another. The development of a well takes about two years and Brotzler estimated will cost about $1.5 million.
Plans call for Well 16 to be located on property within the Bella Vista development. Brotzler said the location is consistent with the city’s water supply plan and well field study.
As part of the process the city will design and construct a third monitoring well in the Jordan formation, in which the city draws its water as well. The monitoring wells are a requirement of the Minnesota Department of Natural Resources.
Brotzler said the city has applied for a Minnesota Department of Health grant to help pay for the costs of the monitoring well.
The city plans to investigate the sites of Wells 1 and 2. Brotzler said the abandoned wells were capped but it is not known if they were sealed. If either was not sealed there is a possibility it could be turned into the third monitoring well. Brotzler said when the city’s first two wells were abandoned the practices were different.
The two monitoring wells online are Test Well 14 which was converted and one that was added last year on the UMore Park property along with the installation of an irrigation well. The third monitoring well will be installed this fall or winter near the center of the city as requested by the DNR.
After the creation of a third monitoring well, the city will design and construct a test well at the site of Well 16 to confirm geology and water quality. Assuming there is no contamination, Brotzler said the well would be constructed.
Council member Vanessa Demuth asked what the city’s policy is regarding elevated levels of radium.
Brotlzer said generally that has not been an issue for the city but that if radium contamination was found at the site of the new well, the city council would have to decide what to do with that information.
The council passed a resolution to begin the development of the well with 4-0 vote. Councilmember Mark DeBettignies was absent from the meeting.
