About Rural Prospector
Last updated: May 12, 2026
What we do
Rural Prospector turns the public well, soil, water-quality, and bedrock datasets that already exist — but are scattered across state agencies, county offices, and federal databases — into a single per-address report a rural property buyer can actually read in the contingency window of a real-estate transaction.
For an address in Minnesota or Wisconsin, the report covers what the well will likely cost to drill (based on the lithology and bedrock depth of neighboring wells), what kind of septic system the soil supports, what water-quality risks the neighborhood carries (arsenic, nitrate, PFAS, coliform), the named aquifer at the property, and the ten nearest neighboring wells with depth, yield, and completion data.
Why it exists
Rural land transactions usually close in 30–45 days. A real on-site well-and-septic assessment takes 2–4 weeks and costs $1,000–$3,000. Most buyers never order one because the timing doesn't fit. The result: people sign a contract on a 20-acre parcel and find out after closing that the well will cost $25K, the soil won't support a conventional drainfield, and the nearest neighbor's well has had nitrate detections.
The underlying data has been public for years — but functionally inaccessible to anyone who isn't a hydrogeologist with a few days to spend in county-records databases. Rural Prospector makes that data legible in 30 seconds for $19.
Data sources
Every datapoint in a Rural Prospector report comes from a public government dataset. We don't buy proprietary data and we don't paywall the underlying records — the report is a translation layer, not gatekeeping.
- Minnesota DNR County Well Index (~3.5M well records)
- Minnesota Department of Health arsenic and nitrate sampling
- Wisconsin DNR Bureau of Drinking Water and Groundwater
- Wisconsin DNR PFAS Study (~32K samples, ~450 monitored wells)
- NRCS gSSURGO soil survey (statewide MN + WI)
- USGS National Aquifer Code Reference List
- Minnesota Geological Survey stratigraphic formations
- Wisconsin Geological and Natural History Survey lithology
What we don't do
A Rural Prospector report is not a site assessment. It is not legal advice. It is not a replacement for a licensed well driller or septic designer who can walk the property. It is a statistical inference from neighboring data — useful for narrowing risk and budgeting, but the final word on any specific property belongs to the licensed professional who actually tests the site.
We say this on every report, every PDF, and every page where money changes hands. Buyers who want certainty about the specific lot should always also engage a licensed well driller and a licensed septic designer.
Coverage
Today: Minnesota and Wisconsin, full coverage. Northern Wisconsin counties (Bayfield, Iron, Vilas, Oneida, Forest, Florence) have thinner per-well water-quality coverage than southern counties — we flag this honestly in any WI report that hits an area with limited data.
Coming next: Michigan, Iowa, North Dakota, and the rest of the upper Midwest. We'll launch new states only after we're confident the data quality meets the bar set by MN and WI — no cosmetic expansion.
