Questions
Frequently asked questions
Is Meridian tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Meridian, PFOS 4.9 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 3.9 µg/L against the 15 µg/L action level. MERIDIAN WATER DEPT (PWSID ID4010097) has a Purity Score of 70/100 (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 Meridian?
MERIDIAN WATER DEPT (PWS ID ID4010097) is the public water system on record for Meridian, Idaho, serving about 152,070 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Meridian get its drinking water?
Groundwater (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Meridian's water?
Yes. In EPA's UCMR 5 testing (2024-09-10 to 2025-09-24), PFOS was measured at 4.9 ng/L against a 4 ng/L federal limit. PFHxS was detected below its limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
Is there lead in Meridian's tap water?
MERIDIAN WATER DEPT's most recent lead 90th-percentile result (2026) was 3.9 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.
What does the latest Meridian water report show?
PurityMap's current record for Meridian holds 31 findings: 2 above a reference, 2 detected within the reference and 27 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.

Something off with your water's smell, color or taste?
Start with the hot-or-cold tap check. Where Meridian Water Dept reported something related, it's shown below.
- Rotten-egg smell
- Cloudy or milky water
- Chlorine smell
- Brown or yellow water
- Metallic taste
Lead at Meridian Water Dept: 3.9 µg/L (90th percentile, 2026 monitoring period (still open)). Lead has no taste, so a taste neither shows nor rules it out.
