Measured, not modelled
Hard Water Feed sells newly filed domestic water wells in California — 393 qualifying filings a year across 2 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 California. 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.
Entry lag not measurable here (received-dated source), so the filing date is already close to the arrival date — no separate lag to carry.
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 California, so there is nothing to sell and nothing we could build that would change it.
CA records a completion AFTER the well exists; it does not issue a pre-drilling construction permit of this kind.

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 California. 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 California are at well water hardness in California.
a completion report was filed with the state; government lab samples in the surrounding grid square; which contractor filed the most recent wells here — 393 qualifying filings a year across 2 territories.
entry lag not measurable here (received-dated source), so the filing date is already close to the arrival date — no separate lag to carry. Delivered weekly.
393 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-california where the sample count supports them.
16 counties across 2 territories. Fresno – San Joaquin Valley covers 6 counties, led by Fresno at 116 filings a year; Modesto – East Bay covers 10 counties, led by Stanislaus at 50 filings a year. Every county is named on this page with the filings it produced, including the ones that produced none.
No. California 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.
