BEAVERTON, Ore. (Portland Tribune) — The city of Beaverton released its 2016 water quality report and it finds that the drinking water supply “meets or exceeds state and federal standards.”

The so-called Consumer Confidence Report found Beaverton’s water showed no dangerous levels of lead, copper, fluoride or nitrates, the latter of which comes from runoff into the city’s water supply from fertilizer use and natural deposit erosion, according to the report.

“The city is committed to providing safe drinking water to its water consumers,” the study says. “To ensure that the city’s drinking water meets state and federal drinking water standards the city collects an average of 140 water samples per month, (or about) 1,680 samples per year, for testing by a state-certified laboratory.”

The primary source of filtered drinking water for Beaverton’s service area comes from the Joint Water Commission (JWC) water treatment plant, of which the city owns a 25-percent share. The plant pumps and filters surface water from the upper Tualatin River and supplements its supply during peak demand periods with water stored in city-owned wells and aquifers.

The JWC plant is able to produce as much as 75 million gallons of potable, drinkable water per day. About 2.55 billion gallons of drinking water were transported by pipeline from the JWC treatment plant through 286 miles of piping into people’s homes, businesses and to help the fire department, the study says.

Three other water districts — West Slope Water District, Raleigh Water District and Tualatin Valley Water District — included in the report passed tests as well. They supply water to about 24,000 residents inside Beaverton’s city limits. The city of Beaverton provides water to the remaining 70,000 people inside its service area.

The annual water quality report, based on monitoring data from 2015, is required annually by the Oregon Health Authority and the U.S. Environmental Protection Agency (EPA).
