Drinking water in Zap, North Dakota is delivered through 1 EPA-regulated community water system serving an estimated 237 people.

PlainEnviro's health-based SDWIS extract shows 2 violation records across the 1 active community system shown here. Monitoring and reporting records are not present in the extract. The records carry 1 distinct EPA contaminant code: Chloramine.
