Update 4: Water Quality Incident - Union Ave Apts

Published:

The following information was provided today to residents at The Club at Oak Creek, Meadowland Villas, and Villas at Union Square:  

 Update (11/21/19) on water quality concern at apartment complex south of Union Avenue

Utility staff has continued to work with the property management companies to investigate the water quality concern reported by one resident late at night on 11/17/19.

Utility staff has continued to flush water from adjacent fire hydrants as a precaution every day.  Utility staff has continued to take chlorine and samples for bacterial analysis.  These have all been normal.  After the night of 11/17/19, there have been no customer complaints regarding unusual water quality concerns. 

A water sample taken on the night of 11/17/19 from the initial complainant’s apartment was tested for a 78 compound volatile organic test sequence by an offsite certified drinking water analysis lab.  The result was normal.  There were no unusual volatile organic compounds detected in the water.

Additional water samples (7) were taken on 11/19/19 and analyzed by the same offsite lab.  The results from all of these samples were normal. 

What does this mean to me?

Is the water safe to drink?  Public water supply entering the apartment complex property from Union Avenue is normal and safe.  Chlorine samples and bacterial samples have all been normal.  There have been no water quality concerns reported in the area.  No unusual volatile organic compounds have been detected in the water samples.  The Water Utility has provided bottled water to the property management companies as a precaution.  The Water Utility will continue flushing on site as a further precaution.

Is the water safe for bathing?  The information above applies here as well.  The Water Utility will continue flushing on site as a further precaution.

Was there a hydrocarbon or volatile organic compound in the water?   A water sample taken at 3:00 am on 11/18/19 from the initial complainant’s apartment was analyzed for 78 volatile organic compounds by an offsite lab.  The result was normal, with no contaminant detected.  7 additional water samples taken on 11/19/19 were analyzed for 78 volatile organic compounds by an offsite lab.  The results were normal, with no contaminant detected.  Additional samples were gathered on 11/20/19 but the results are pending.

What was the source of the combustible gas measurements at low levels?  The detector used by Sheboygan Fire Department measures the presence of various gases including methane, propane, natural gas, and others.  The detector is not intended for water sampling.  In the buildings on Skyline Drive and Hillshire Drive, the results were due to natural gas leakage.  In the buildings on S. Promenade Circle, Diamond Lane, and Gazebo Lane, no apparent source has been discovered.

When will we receive further updates?  Any new information will be available at the following locations:  SheboyganWater.org, NextDoor, and Facebook.com/SheboyganWaterUtility
