Park City water meets almost all standards
July 24, 2012
The contaminants found in Park City’s drinking water are below the maximum allowed by regulation in all but one category, the Park City Water Department says in a flier that was recently delivered to Parkites.
The level of antimony, something that occurs naturally, continues to exceed regulations at some points. The flier indicates the antimony level ranges from not being detectable to 7.1 parts per million. Regulations limit the amount to six parts per million.
People who drink water for many years with antimony well above six parts per million are at risk of an increase in cholesterol and a decrease in blood sugar.
Clint McAffee, City Hall’s water manager, said the municipal government and state drinking water officials earlier reached an agreement giving the city until mid-2014 to address the antimony levels.
He said the solution will involve piping water from the Judge Tunnel source to the new treatment plant at Quinn’s Junction. The water will be treated and blended with other municipal water sources, reducing the antimony level, he said.
McAffee anticipates starting to build a pipeline from the Judge Tunnel to the treatment plant in spring 2013.

The level of other contaminants sometimes approaches the maximum allowed but does not exceed standards, according to the flier. Arsenic has been found at up to seven parts per billion, under the 10 parts per billion allowed. Cadmium has been found at levels up to 4.9 parts per billion, just below the 5 parts per billion standard.
"I think it’s absolutely safe. I drink it straight out of the tap," McAffee said about the municipal water system.
The flier — the annual water quality report for 2012 — was recently mailed to all postal addresses in Park City. The state requires the report be published every year.
The flier also provides an outline of City Hall’s waterworks system, which Park City leaders have for years have said is highly complex given the various sources and pumping systems needed to serve the different elevations.
It mentions that Park City’s water comes from well, spring and tunnel sources. It also briefly touches on the treatment plant at Quinn’s Junction.
Meanwhile, the amount of water Parkites have been using has dropped since early July. McAffee said more water was used on Independence Day than any other day in Park City’s history. He said 15 million gallons of water were used on the 4th of July.
The number later dropped to approximately 12.5 million gallons per day.
City Hall since early July has had the source capacity to produce approximately 17.2 million gallons in a day.
