[ARCHIVED] Water Quality

*UPDATE 08/31/2018.  Water tests have passed!

Staff has been very concerned about the failing water tests for the Maywood/Deerwood Drive neighborhood related to water main work in this area.  Failed tests associated with construction activities are not uncommon, but this situation had gone on longer than one would expect.  Because of our concerns, we have been conducting sampling outside the project area the week of August 20th.  The tests revealed that we have total coliform in a portion of our active water distribution system.  (See map for affected area).  As a point of reference, we completed a city-wide sampling of the water for routine water monitoring as required by the Minnesota Department of Health (MDH) for the on-going operation of our water system on August 15th.  All eleven of those random samplings passed MDH requirements and standards.  Therefore, our issue is of recent origin. 

Citing the MDH, total coliform bacteria is common in the environment (usually found in soil) and is generally not harmful.  The source of total coliform is most likely from contamination from the environment, introduced during construction or while repairs to plumbing or a water main were underway (See MDH Consumer Notice for additional information).   The City currently has two construction projects in this area that could be possible sources of our problem.  It should be noted that E. coli bacteria, a group of potentially harmful bacteria, has also been tested for and was not detected in our water supply. 

While our failed tests do not imply an imminent health threat, the City wants to have this issue resolved as soon as possible.  To address the problem, we are flushing the water mains in the affected area, temporarily adding chlorine to the water system in the affected area, and continuing to sample around the community to ensure the limits of the problem are confined and dealt with appropriately.   We are working with the MDH to correct this issue as quickly as possible.  

As users of the water system, what should you do?  According to MDH’s Consumer Notice, you may drink the water.  However, if you have specific health concerns, you may want to consider an alternate source of water for consumption such as bottled water or boiling of water for one minute.  

While the MDH has not required the City to provide this notice, we do want transparency and accountability as we work through this issue.  We also want to ensure that accurate information is available to the community.  To help answer further comments and questions, we have created a INFORMATIONAL LINE.  That number is 651-554-3291 and will be staffed from 8:00 a.m. to 4:30 p.m. on regular business days. Once this issue is resolved, we will place a notice on the City’s website and Facebook page.  

Your patience and understanding is appreciated as we deal with this matter.
