Getting the Lead Out of School Drinking Water Results

June 15, 2023

Lead in Water Testing Initial Test Results

On June 9^th we received the results from the first round of lead testing. In accordance with statute, these results are being communicated to parents and staff via written notification within seven business days.

• Total test points sampled—75
• Total samples with lead detected—26 (34.7%)
• Total samples with lead levels above the action level of 5ppb—20 (26.7%)
• All drinking fountains tested below 5ppb. All other actionable sample results are from hand sinks and showers.

Immediate actions:

In accordance with guidance from the EPA, the affected faucets or outlets have signage placed to indicate it is non-potable, not for drinking, or washing dishes. This signage can be temporary since testing is still in progress to localize the source of lead contaminants.

Next steps:

Follow up flush samples will be collected per EPA and DHSS testing guidelines. Scheduled for 26 June, 2023.

Lab report and flush sampling plan are available here.

Testing criteria:

Each sample was tested for total lead content which includes dissolved and particulate. The elevated level is defined as a level of lead ≥ 5pbb. Sampling was conducted per EPA test guidelines by initial draw after stagnation (periods of non-use that exceed eight hours).  This manner of testing is the first step in localization and is paired with follow-up flush testing to further localize the source of any elevated levels. 

Explanation of results:

75 test samples were submitted for testing.  26 were returned with detectable levels.

20 initial draw samples tested ≥ 5pbb total lead. See the follow-up flush plan below for required testing.

Remediation:

These are efforts to mitigate and correct the levels of lead to which children and staff are exposed: The remediation plan will be posted when follow-up flush testing results are received and fiduciary constraints as well as maintenance availability have been considered.
