Rosemount released its water quality report last week and while in years past they have mailed it to residents, this year they have simply put the results on the city's website.
The Minnesota Department of Health, which regulates water quality, changed their policy, allowing the city to publish the report electronically.
The 2011 Water Quality Report states that no contaminants were detected at levels that violated federal drinking water standards. Some contaminants were detected in trace amount in 2011, though. According to the report drinking water, including bottled water, may reasonably be expected to contain at least small amounts of contaminants. The report covers the monitoring done on drinking water from Jan. 1 to Dec. 31 2011.
"We are fortunate in Rosemount to have a good quality ground water source," said public works director Andy Brotzler.
Rosemount draws water from the Jordan aquifer through eight wells. According to the water quality report the water is chemically treated with chlorine to disinfect, fluoride for improved dental health and polyphosphates to prevent naturally occurring iron.
Water is tested for a variety of contaminants including microbial, inorganic, pesticides and herbicides, organic chemicals and radioactive contaminants. The U.S. Environmental Protection Agency sets the limits for the amount of contaminants in water provided by public water systems.
The department of health requires the city release an annual drinking water report. However, Brotzler said the city monitors water quality constantly.
"If issues come up we know about them right away," said Brotzler.
The report is technical but provides some valuable information. Brotzler said they follow the department of health's standards when creating it. The purpose of the report is to advance residents' understanding of drinking water and to raise awareness to protect water resources.
The Water Quality Report is available on the city's website at ci.rosemount.mn.us. Residents who would like to obtain the entire water assessment can call 651-201-4700 or view it online at www.health.state.mn.us.
