Measured, not modelled
Hard Water Feed sells newly filed domestic water wells in Michigan — 8,835 qualifying filings a year across 4 territories — each matched to measured laboratory water hardness and sold to one water-treatment dealer per territory, exclusively.
Four signals exist in this business. 3 of them are sold in Michigan. The other is listed below with the reason it is not.
Who it is: a household whose well was just finished. What happened: a completion report was filed with the state. Why they need you: they have well water for the first time, or from a new source, and have not yet tested or treated it.
Median 14d behind the event.
Who it is: any property in the territory. What happened: government lab samples in the surrounding grid square. Why they need you: it is the number that decides whether a softener is worth selling and at what size — and no state publishes it with well records.
Who it is: the drilling company working a territory. What happened: which contractor filed the most recent wells here. Why they need you: a referral channel and a competitor map — the driller is already on site when the household has no treatment yet.
This event does not occur in Michigan, so there is nothing to sell and nothing we could build that would change it.
MI records a completion AFTER the well exists; it does not issue a pre-drilling construction permit of this kind.

Qualified filings are new domestic wells in water hard enough to be worth treating, over the trailing year. One dealer per territory.

Your branding, your phone number, your offer. Every bracketed value is a placeholder — the real card carries the measured hardness reading for that specific property, and the map is Michigan. We print and mail it; you get every address we mail, in the same weekly delivery.
Every row carries the property, the measured hardness at that property, the county, the filing date and the driller. See a real doorstep report — the sheet a dealer leaves at the door — and how every figure is derived.
Sample rows are not published here. The addresses are the product, and a page that showed them to rank for this query would be giving it away.
Laboratory samples published by Water Quality Portal (USGS & US EPA), joined per property rather than averaged over a municipality. County figures for Michigan are at well water hardness in Michigan.
a completion report was filed with the state; government lab samples in the surrounding grid square; which contractor filed the most recent wells here — 8,835 qualifying filings a year across 4 territories.
median 14d behind the event. Delivered weekly.
8,835 filings a year qualify in the territories sold here — new domestic wells in water hard enough to be worth treating. The state's total filing count is higher; this is the qualifying subset.
Hardness is measured per property from government laboratory samples rather than estimated from municipal averages. County-level figures are published at /water-hardness-michigan where the sample count supports them.
52 counties across 4 territories. Traverse City covers 10 counties, led by Grand Traverse at 233 filings a year; Grand Rapids covers 23 counties, led by Kent at 525 filings a year; Detroit – north covers 13 counties, led by Oakland at 490 filings a year; Northeast Michigan covers 6 counties, led by Ogemaw at 159 filings a year. Every county is named on this page with the filings it produced, including the ones that produced none.
No. Michigan records a completion after the well exists — there is no pre-drilling permit of that kind to sell. Florida is the only state here where that event occurs, and it is sold there.
