• The EPA standard for acceptable lead levels in drinking water prior to legislative approval of RSMo 160.077 was less than 15 ppb (parts per billion).

• The Get the Lead Out of School Drinking Water Act now requires that school building water sources contain a lead content of less than 5 ppb.

• If all tested water sources in a building test less than 5 ppb, that building will not be required to test again for a five year period.

• If a water source is identified to be producing lead levels greater than 5 ppb, annual testing will be required for that building until remediation efforts are proven successful.

• The district is only responsible for testing water sources that are defined as drinking water sources or water sources utilized for food preparation; however, Lindbergh Schools tested all water sources in order to better understand each facility and keep students and staff safe.

• All non-applicable water sources will require signage to be installed in an effort to indicate the water is non-potable and not intended to be a source of drinking water.

Drinking Fountains

Through the testing process, three drinking fountains were identified as having a lead count of more than 5 ppb. These drinking fountains were immediately turned off, and replacement filters were ordered and installed on each. Each fixture will be retested to ensure successful remediation before the start of the 2024-25 school year.

Kitchen Sinks

Replacement faucets are being sourced for all kitchen sinks testing higher than 5 ppb. The new faucets will be installed before the start of the 2024-25 school year, and each fixture will be retested to ensure successful remediation.

Labeling Non-Potable Water Sources

All other fixtures that are not sources of drinking water will be labeled “Non-Potable Water: Do Not Drink,” in order to ensure safety and awareness for our community.
