Lead Testing Update

Lead in Drinking Water Sample Results
Posted on 06/16/2021
As of June 1, 2021 the action level for lead in drinking water in all Maryland public and nonpublic schools has been lowered from 20 parts per billion (ppb) to 5 ppb.  Per the new regulation, all previous sampling results must be assessed, and action taken on fixtures with results between 5 ppb and 20 ppb.  This includes issuing an updated notification. 

The Board of Education of Baltimore County already established a standard of 5 ppb for our schools and remediation has already occurred for these fixtures.
