The City of Edina has 200 miles of water mains, 360 miles of sanitary and storm sewer mains, 18 deep water wells and 5 water treatment plants delivering up to 22 million gallons of water per day.
Not every city well is filtered for the removal of iron and manganese. Iron and manganese can result in discolored water that can result in taste or odor complaints. The City does have a long-term goal to eventually filter all of its wells.
The Morningside area is serviced by Minneapolis which gets its water from the Mississippi River. Seasonal low river levels and algae blooms can cause a fishy, musty odor, and brown discoloration. There is also a long term plan to resolve this.
The EPA has established two standards for additional contaminants in tap water:
MCL: Maximum Contaminant Level - The maximum allowable level of a certain contaminant
MCLG: Maximum Contaminant Level GOAL - The level where studies have found ZERO HEALTH RISKS, aka the "Health Limit"
Certain contaminants that absorb easily through your skin have been highlighted in orange. For those items, a Point of Entry (POE) system is recommended to treat all the water for your home/business.

Vinyl Chloride is a known carcinogen that was first detected in Edina city water back in 2003.
According to the Minnesota Pollution Control Agency, long-term exposure to Vinyl Chloride can lead to liver damage and liver cancer.
By summer 2012, Edina plans to have completed a water treatment system to address contamination that has now been found in other Edina wells.
