Testing for Lead in Drinking Water
Charles County Public Schools (CCPS) is testing schools and centers for the presence of lead in school drinking water. CCPS is conducting the testing to comply with a new state regulation, HB 270, which was signed into law in May 2017 and requires schools served by public water to test for the presence of lead. All Maryland schools, public and nonpublic that serve students in prekindergarten to Grade 12, must complete the testing. The testing is not the result of any concerns with drinking water in Charles County schools.
The previous lead action level under Maryland law was 20 parts per billion (ppb) and was in effect through May 31, 2021. As of June 1, 2021, the lead action level is 5 ppb.
Testing is limited to water outlets where the water is intended for consumption. This includes water sources like drinking fountains, cafeteria sinks, classroom combination sinks, teachers’ lounge sinks and any other outlets used for drinking or food preparation. It does not include water outlets like utility and bathroom sinks. CCPS will place signs on non-drinking outlets that are not subject to water sampling indicating they have not been sampled. Signs do not indicate that a particular water outlet has lead contamination.
Although not required by law, CCPS plans to test the water at all schools, including those where water is provided by a well, educational centers and office buildings. Staff will test the more than 30 CCPS schools and buildings in the 2021-2022 school year. Details about testing procedures and other information is included in the Frequently Asked Questions.
CCPS will send all water samples to Martel Laboratories JDS Inc., a state-certified laboratory for water analysis. CCPS will post results on schools and centers websites as we receive them and CCPS will post full lab reports and summaries on this webpage.

Lead in Drinking Water Test Results
Maryland Department of the Environment (MDE) recommends water outlets be taken out of service if the lead level exceeds 5 parts per billion (ppb). When a water outlet exceeds this level, the outlet is disabled within 24 hours to prevent physical access to the water coming from the fixture. A follow-up sample is collected and if the results have lead levels exceeding the action level, the fixture is replaced.
