Nebraska Tap Water Quality Report

The tap water quality in Nebraska currently sits near the national average, registering a composite safety score of 65.4/100 across 621 monitored ZIP codes. While a significant portion of the state maintains adequate water quality and full compliance with federal standards, 2% of ZIP codes in Nebraska have received a failing grade due to recent compliance issues. Monitoring data from the EPA indicates that while the majority of residents receive safe tap water, localized issues remain a challenge for several municipal systems.

Over the past 5 years, water utilities in Nebraska have recorded a total of 1,153 violations, of which 323 were strictly health-based. While administrative and reporting violations are common nationwide, health-based violations mean that certain contaminants exceeded the EPA's Maximum Contaminant Levels (MCLs) at some point. Nebraska Department of Environment and Energy, which acts as the primary regulatory authority in the state, typically works closely with these utilities to issue boil water advisories or mandate infrastructure upgrades when these limits are breached.

One of the most pressing concerns for Nebraska residents is the elevated risk of lead exposure. EPA models and historical monitoring indicate that 81.2% of ZIP codes in Nebraska are classified as High or Very High risk for lead. This is frequently associated with older housing stock built before the 1986 federal ban on lead pipes and solder. Residents living in older homes should strongly consider having their tap water independently tested and utilizing a certified NSF/ANSI 53 water filter for drinking and cooking.
