“Elevated levels of copper in the water of several Langley homes could have the city treating its water with ozone in the future.Personnel from the state Department of Health found the copper while re-testing water from several homes where the water tested high for lead in June.During a presentation to Langley City Council earlier this month, Rick Hill, the city’s director of public works, reported that lead levels in the homes are now at an acceptable level, but copper levels are higher than the maximum set by the health department. That maximum is 1.3 milligrams of copper per liter of water.Homes in which the water was sampled were chosen at random. Hill said there could be about 30 homes in the city that have similar copper levels to those found failing the random test. Hill said the source of the copper contamination is not the city’s water supply. Water from the city’s wells tested normal for copper. He said the most likely culprit is the service pipes leading into the affected homes, which contain copper. Langley Mayor Lloyd Furman said there are several water treatments the city could use at its wells to reduce the copper levels in individual homes.If there’s something we can do, we’re going to look at it, Furman said.Hill said the city will look most seriously at using ozone to treat the city’s water.Since the city will not test the water in every home within the city limits, homeowners concerned about the levels of heavy metals in their water need to do their own testing. Homeowners can get their water tested through the state Department of Health. To do so, pick up a water sample bottle at Langley City Hall, fill it with tap water at home, then return the bottle to City Hall. The state will test the water and give homeowners the results. The test costs $22.”
