Frequently asked questions
Is Cold Springs tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Cold Springs, PFAS were detected below their limits, and PFPeA 6.2 ng/L with no federal or state limit; one health-based violation is on record (E. coli). GREAT BASIN WATER CO COLD SPRINGS (PWSID NV0000207) has a Purity Score of 99/100 (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 Cold Springs?
GREAT BASIN WATER CO COLD SPRINGS (PWS ID NV0000207) is the public water system on record for Cold Springs, Nevada, serving about 9,910 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Cold Springs get its drinking water?
