Questions
Frequently asked questions
Is Milbank tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Milbank, the lead 90th-percentile result was 2 µg/L against the 15 µg/L action level. MILBANK (PWSID SD4600207) 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 Milbank?
MILBANK (PWS ID SD4600207) is the public water system on record for Milbank, South Dakota, serving about 3,544 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Milbank get its drinking water?
Groundwater (primary source of record in EPA SDWIS).
Is there lead in Milbank's tap water?
MILBANK's most recent lead 90th-percentile result (2025) was 2 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 Milbank water report show?
PurityMap's current record for Milbank 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.
