Lead Testing Results – Carson City
Below are the test results to date for the WIIN project testing of lead in drinking water for child care centers in the county you selected. Use the search bar in the upper right of the table to search by facility name or Facility ID. Results are updated as they are received from the laboratory, beginning in early 2022 when the project begins and continuing through 2024. Information on how to interpret the results can be found below.
Initial Sampling Results
Follow Up Results and Corrective Action
Initial results above the project action level of 15 ppb will complete follow-up testing. Initial results are in the first table, follow-up results are in the second table
How To Interpret Results
SOURCE ID: This is a unique number used to identify each water source (i.e. a specific sink, drinking fountain, water cooler, or other fixture) at a facility.
FLOOR & ROOM NUMBER: Are used to locate each water source within a facility.
INITIAL LEAD TEST RESULT: Parts per billion (ppb) is a measure of the concentration of lead within a water sample. Sources with “<1” means that the lab did not detect lead over 1 ppb, which is the lowest amount that can be detected with the test. This project used 15 ppb as the action level. The action level is the level above which the tap must be blocked off and restricted from use until the source of the problem can be identified. All water sources above the action level of 15 ppb will be addressed.
FOLLOW-UP LEAD TEST RESULT: Follow up sampling is performed on all water sources that initially tested above the project action level and includes a repeat first draw sample and a flushed sample. First draw samples generally represent the impact of lead from the fixture/faucet. Flushed samples generally represent the impact of lead from the plumbing deeper in the wall.
Lead levels in drinking water can frequently change and in some cases, the follow up sampling may show less lead than the initial samples. However, any tap that tested above the project action level during any of the sampling has the potential to expose children to lead will be addressed. Possible actions include replacement, removal from service or conversion to a handwash only station. In some cases, a certified lead-free filter can be safely used to prevent lead exposure. Filters must be maintained and changed according to manufacturer’s instructions.
Because lead is harmful to children even in small amounts, child care centers may choose to take corrective action to decrease the lead present in the drinking water for taps with levels less than 15 ppb. Corrective action for these moderate levels of lead include such options as:
- Flushing the water before use until a uniform temperature is reached (no less than 30 seconds)
- Using a filter certified to remove lead
- Frequent cleaning of aerators
- Using the identified fixture for handwashing only and using bottled water for drinking/cooking
- Replacing the faucet or plumbing with certified lead free materials
MORE INFORMATION: Children can be exposed to lead from many sources in their homes and communities.
- If you are concerned about your child’s potential lead exposure please contact your child’s doctor to discuss blood lead testing.
