WaterOne, Johnson County’s water utility, released its annual report late last week showing that the water coming out from the taps here is “meeting and exceeding state and federal quality standards for purity and taste.”

WaterOne says it conducts more than 120,000 tests on more than 18,000 water samples each year to get its measurements of potential contaminants, including elements like lead and barium. This year’s report showed that contaminant levels remained largely constant from 2013 to 2014 in most categories, and well below the goal levels set by federal and state standards.

The 2014 report did show an increase in the level of fluoride from .81 parts per million in 2013 to 1.48 parts per million in 2014. The goal level for fluoride is below 4 parts per million. There was also an increase in the selenium level from 2.6 parts per billion in 2013 to 3.4 parts per billion in 2014. The goal level for selenium is below 50 parts per billion.

WaterOne serves more than 400,000 people in the Johnson County area, and treated more than 10.7 billion gallons of water from the Kansas River and 12.1 billion gallons from other sources last year. The utility reports that tap water delivered to people’s homes costs less than a penny per gallon.
