Lead Testing Results for McKinney Elementary School
To the staff and parents of McKinney Elementary School,
Over the summer, we conducted water testing at all District facilities and have been awaiting the results, which are coming in one-by-one. We just received the report for McKinney Elementary School, where 50 possible sources of drinking water were tested. Results are that the first-draw samples from five outlets indicated an elevated level of lead (see locations below). However, upon testing the flush samples from each of these outlets we learned that four of the five had results below the EPA’s recommended action level of 20 parts per billion (ppb), while one had a result just above the action level. Therefore, we will be replacing the fixtures at the four locations where the flush test was below the action level and returning the outlets to service as potential sources of drinking water at the school. At the location where the flush test was above the action level, we will be capping the water source until such time as Facilities can investigate and mitigate the source of the lead. The fixture will then be replaced and additional testing will be conducted. Only when further testing reveals that the water source has a lead concentration below the action level will that water source be returned to service as a possible source of drinking water.
Please visit the Environmental Testing page on the District website for additional information.
