In October 2022, with the support of a grant from the federal Environmental Protection Agency (EPA), the Delaware Department of Education (DOE) with support from the Delaware Division of Public Health (DPH) began a sampling initiative to conduct lead testing at every water consumption point in every public school in the state.

The Delaware Department of Education announced on December 13, 2022, that it had contracted with a private firm, Batta Environmental Associates, to retest all fixtures that initially tested at 7.5 ppb or higher and all consumption points at schools statewide.

Retesting began in late December 2022 and will continue for the next three to six months. Test results and any necessary mitigation efforts will be posted to this page as they become available.
