Important Information for Schools Testing During the 2020-2021 School Year
Maryland’s regulations require schools to test for the presence of lead in all drinking water outlets on a State-established three-year cycle, unless a waiver from future testing has been granted. Since testing is required to be conducted when schools are in regular session, closures and capacity reductions resulting from the ongoing COVID-19 pandemic may have disrupted such testing previously planned during the 2020-2021 school year. Click on the links below to find additional information regarding the testing requirements and procedures, and advice about best flushing practices to enhance water quality in school buildings during the 2020-2021 school year:
Schools that plan to test during the 2020-2021 school year should conduct the complete round of standard testing with all samples collected before the end of the testing period (i.e., July 1, 2021) or by the end of the 2020-2021 school year, whichever occurs sooner. The schools have 14 days (from the date of sample collection) to submit samples to a MD-certified laboratory, where the samples must be analyzed within 6 months of preservation. The school shall then report all test results to MDE, MSDE, Maryland Department of Health (MDH), and the appropriate local health department within 30 days of samples being analyzed by the laboratory. This may be accomplished by submitting required reporting documents to testresults.leadschoolwater@maryland.gov.

Summary of Results
As of March 1, 2023, MDE has received and verified a total of 79,745 first-draw lead sample results from 24 public school systems, 247 nonpublic schools, and 17 charter schools.

Of the 79,745 first-draw lead samples, 12,452 (15.61%) samples exceeded 5 ppb (i.e., current Action Level effective June 1, 2021): 7,634 (9.57%) were from drinking water outlets (i.e., consumption outlets), 4,816 (6.04%) were from non-consumption outlets, and 2 (0.003%) were from outlets with unknown use (i.e., a use determination could not yet be made).
The following tables present the above information in greater detail and will be updated as more data become available.
