Questions
Does Nebraska tap water have PFAS?
EPA tested 51 community water systems in Nebraska for 29 PFAS between 2023 and 2025. 6 had at least one regulated PFAS detected, and 3 had an entry-point average above a 2024 federal limit. Those 3 systems serve about 83,158 people (5% of people on community water in Nebraska). Systems have until 2029 to meet the limits.
How many Nebraska water systems have violations?
151 systems in Nebraska had at least one health-based violation since 2016 (663 violations in total). 71 violations are currently listed as unaddressed.
Which Nebraska water systems are over the lead action level?
7 systems had a lead 90th percentile above the 15 ppb action level in their most recent results from the last five years. Another 6 systems have no lead results in EPA's database from the last five years. Lead depends on each home's pipes, so a test of your own tap is the only way to know your level.
