North Wasco County School District 21 says recent testing at five school sites showed no actionable levels of lead in drinking water.  Testing was performed in mid-June at Dry Hollow, Colonel Wright, and Chenowith elementary schools, The Dalles High School, and the Wahtonka campus, which are D-21’s oldest buildings.  Of the 72 individual samples taken, none was above the U.S. Environmental Protection Agency’s action levels for either public water drinking systems or school water supplies.  Mosier Community School had a test performed separately and showed no actionable levels of lead in their drinking water.  Testing will be conducted at The Dalles Middle School before the start of school.  Oregon schools are not currently required to test drinking water for lead, but in early June state school and health authorities recommended taking such action.  Of the 72 individual samples taken, none was above the U.S. Environmental Protection Agency’s (EPA) action levels for either public water drinking systems or school water supplies.
