The table below contains all results to date for the Lead Testing in School and Child Care Program. Use the filter option to search results by facility name, city, and more. Results are updated as they are received from the laboratory. Information on how to interpret the results is below.
Outlet ID: This is a unique number used to identify each drinking water outlet (e.g., drinking fountain, classroom sink, or kitchen faucet) where sample(s) are collected.
Outlet Location: The unique location (floor number and room number) where the drinking water outlet is located.
Initial First Draw Result (ppb): A first draw sample is collected immediately after turning on the faucet or fixture. Water was previously unused for a period between 8 to 18 hours. Parts per billion (or “ppb”) is a measure of the concentration of lead in water.
Initial Flush Result (ppb): A flush sample is a sample collected after the first draw sample and after water has run for 30 seconds. Parts per billion (or “ppb”) is a measure of the concentration of lead in water.
Follow Up First Draw Result (ppb): Follow up samples are also collected after initial results have been returned and are used to help understand possible sources of lead. A first draw sample is collected immediately after turning on the faucet or fixture. Water was previously unused for a period between 8 to 18 hours. Parts per billion (or “ppb”) is a measure of the concentration of lead in water.
Follow Up Flush Result (ppb): Follow up samples are also collected after initial results have been returned and are used to help understand possible sources of lead. A flush sample is a sample collected after the first draw sample and after water has run for 30 seconds. Parts per billion (or “ppb”) is a measure of the concentration of lead in water.
Result Notes: Information related to sample collection, the drinking water outlet, or remediation measures.
Unverified Sample Protocol: A sample with this label was not collected following required sampling steps. The school or child care program must recollect samples using required sampling steps to ensure correct sample result interpretation. These steps could include water stagnation period, pre-stagnation flush timing, or flush sample collection timing.
Unable to be Sampled: According to the information provided on the Chain of Custody form, the outlet was inaccessible or not working on the day of sample collection.
Unable to be Analyzed: The laboratory was not able to analyze the sample. Reasons could include that the sample was damaged during transit, an insufficient volume of water was collected, or the sample was not labeled properly.
Sample Not Received: According to the information provided on the Chain of Custody form, the sample was collected. However, the laboratory did not receive the sample.

Unable to be Sampled: According to the information provided on the Chain of Custody form, the outlet was inaccessible or not working on the day of sample collection.
Unable to be Analyzed: The laboratory was not able to analyze the sample. Reasons could include that the sample was damaged during transit, an insufficient volume of water was collected, or the sample was not labeled properly.

The data displayed reflect the results of water samples collected from public schools and licensed child care centers across the State of Tennessee. All laboratory analysis is performed in accordance with EPA Method 200.8 for lead in drinking water. The results represent lead concentrations in the specific water samples collected at a particular point in time.
Lead in drinking water originates from lead-containing plumbing materials. It is important to note that lead levels can fluctuate due to various factors including changes in water usage, stagnation time, plumbing modifications, and variations in the water supply.
Sample sites are selected based on observations of water fixtures used by students and staff for drinking or food preparation However, they do not include every water outlet or scenario in the facility (e.g., non-potable locations or fixtures used exclusively for cleaning).
The Tennessee Lead Testing in Schools and Child Care Centers program is an ongoing effort to reduce lead in drinking water through testing, mitigation, and routine maintenance.
