Questions
Frequently asked questions
Is Cimarron City tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Cimarron City, the lead 90th-percentile result was 1.7 µg/L against the 15 µg/L action level. LOGAN CO RWD #2 (PWSID OK2004206) has a Purity Score of 60/100 (confidence: low), 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 Cimarron City?
LOGAN CO RWD #2 (PWS ID OK2004206) is the public water system on record for Cimarron City, Oklahoma, serving about 1,146 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Cimarron City get its drinking water?
Groundwater (primary source of record in EPA SDWIS).
Is there lead in Cimarron City's tap water?
LOGAN CO RWD #2's most recent lead 90th-percentile result (2026) was 1.7 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 Cimarron City water report show?
PurityMap's current record for Cimarron City holds 2 findings: 1 above a reference and 1 detected within the reference. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
