Making water quality information accessible to all Minnesotans
We believe every Minnesotan has the right to know what's in their drinking water. Our platform makes it easy to check water quality by simply entering your address—no need to navigate complex government databases or interpret technical reports.
By aggregating data from official government sources and presenting it in a clear, accessible format, we help residents make informed decisions about their water safety.
All water quality data comes from official government sources:
Water system information, EPA violations, compliance records, and service area boundaries
Lead and nitrate concentration measurements from water quality testing
Water systems receive letter grades (A-F) based on three key factors:
EPA action level is 15 ppb. Systems well below this threshold score higher.
EPA maximum contaminant level is 10 ppm. Lower nitrate scores higher.
Systems with no PFAS detected receive full points. Detection results in point deduction.
We take your privacy seriously:
We're continuously improving this service. If you have questions about your water quality or suggestions for new features, we'd love to hear from you.
