The DC Public Library recently tested lead levels in drinking water sources, including water fountains and kitchenette sinks, in all public library locations in D.C.

In District government buildings, a drinking-water sample has to contain less than five parts per billion of lead, making it as safe as bottled water. In September 2019, samples were taken from Library drinking water sources and sent to a lab for analysis. The test results show that all Library drinking water sources are below the actionable level.

In September 2016, filters were installed on all drinking-water sources at Library locations. Since that time, filters have been changed annually. Filters were also installed at drinking-water sources at Library locations opened since September 2016. The Library will continue to filter all drinking-water sources.

You can find the results of lead testing at all D.C. public libraries below.

Your safety is paramount. If you are concerned about your health or the health of your family, we recommend you contact your family physician. If you have any additional questions or concerns, please contact Matthew Johnson, Risk Manager at the DC Public Library at Matthew.Johnson6@dc.gov.
