Maryland tap water, in plain English
Here is what the EPA's own data shows about tap water in Maryland. According to EPA SDWIS data retrieved June 2026, Maryland is served by 1 active community water system, together reported to serve about 140 people.
As of June 2026, EPA records show 176 violations across the community water system(s) serving Maryland, going back to the earliest EPA record. 2 of these are classified by the EPA as health-based (a contaminant recorded above the limit the EPA tracks); the rest are monitoring or reporting violations. Each is listed by system below, with its status.

What this means
A health-based violation means a contaminant was recorded above the limit the EPA tracks for it. A monitoring or reporting violation means a required test or report was late or missed — not that a contaminant was measured above a limit. “Returned to compliance” means the EPA recorded the issue as resolved.
