Questions
Frequently asked questions
Is Grand Island tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Grand Island, PFHxS 24.6 ng/L (limit 10 ng/L) and PFOS 7.5 ng/L (limit 4 ng/L) were measured above their limits in EPA's 2024 testing; the lead 90th-percentile result was 1.98 µg/L against the 15 µg/L action level; one health-based violation is on record (Uranium). GRAND ISLAND, CITY OF (PWSID NE3107902) has a Purity Score of 52/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
Who provides tap water in Grand Island?
GRAND ISLAND, CITY OF (PWS ID NE3107902) is the public water system on record for Grand Island, Nebraska, serving about 51,478 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Grand Island get its drinking water?
Groundwater (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Grand Island's water?
Yes. In EPA's UCMR 5 testing (2023-04-10 to 2023-10-17), PFHxS was measured at 24.6 ng/L against a 10 ng/L federal limit and PFOS was measured at 7.5 ng/L against a 4 ng/L federal limit. PFBS (4.8 ng/L, below the 2,000 ng/L EPA health advisory) was also detected. PFPeA (3.4 ng/L) was also detected; it has no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
Is there lead in Grand Island's tap water?
GRAND ISLAND, CITY OF's most recent lead 90th-percentile result (2023–2025) was 1.98 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
Has Grand Island's water system had violations?
The federal SDWIS record lists a health-based violation for GRAND ISLAND, CITY OF within about the last ten years: Uranium (2025). The findings above show each one's status.
What does the latest Grand Island water report show?
PurityMap's current record for Grand Island holds 32 findings: 4 above a reference, 2 detected within the reference, 1 detected with no limit and 25 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
