Lead Testing at DC Public Library

Lead Testing at DC Public Library

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.   

During the first two weeks of June, 122 drinking water sources were tested with 244 samples taken from these sources and sent to a lab for analysis. Out of 122 drinking water sources, the analysis shows 115 drinking water sources are below the actionable level and seven water sources at four library locations are above. The seven water sources are a kitchenette sink at Georgetown Library; a water fountain at Lamond-Riggs Library; four water fountains, including three fountains in staff and mechanical areas; at the Martin Luther King Jr. Memorial Library and a water fountain at Southwest Library.

The Library immediately shut off the sources that registered above the actionable level and posted signs informing residents not to drink from these sources. The Library is in the process of repairing the sources by installing filters or replacing equipment. We will re-test the water source and restore only if the issue is resolved.

The DC Public Library and its contractors follow the EPA’s guidelines to determine if there is an actionable amount of lead or other unsafe substances in drinking water. If a high level of lead or any other unsafe substance is found, steps are taken immediately to prevent library users and staff from drinking the water.

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