There are 23 territories, across 8 states.

Not a limit we set — that is how many service areas have enough new domestic wells in hard water to fill a weekly list. Every map below is drawn from the wells themselves and every count is measured from that state’s own well records. You can check it.

Territory: The counties within 75 miles of its anchor — roughly how far a dealer will drive.
Qualified/yr: New domestic wells in water hard enough to sell into, measured from that state’s own filings over the last year. A * means the state does not confirm every one of these as new rather than a replacement — see the footnote below the tables.
Hardness reading: The share of delivered leads whose hardness comes from tested wells in that property’s own ~7-mile grid square rather than from the county median. Both are real measurements; this is how local they are, and it is not the same in two territories.
Price: Volume alone. A large territory on county-level readings costs more than a small one on property-level, which is why both numbers are here rather than one blended score.

States shown largest first: Michigan, Florida, Texas, Ohio, Minnesota, Wisconsin, Missouri, Idaho.

* Michigan and Minnesota do not publish whether a well is new or a replacement, so a starred count may include a redrill or deepening at an existing household rather than a household that just got water for the first time. Some Florida territories are a MIX — the state publishes it for part of the territory and not the rest.

Why you get a territory and not a county

Most counties see fewer than one qualified lead a week, and filings arrive in bursts rather than evenly — drillers file their paperwork in batches — so a county averaging one a week sends nothing at all about a third of the time. Sold as single counties, most of every state is an empty inbox.

Grouped into areas a dealer can actually drive, the same volume supports the territories above. Areas that fill a list most weeks but sit under the volume floor are not sold at any price. Below 500 qualified leads a year the subscription doesn’t pay a dealer back, and a territory that loses money is worse for both of us than no territory. That is the whole reason the count is what it is: the wells are not there.

What decides your price

Territories are priced by how many qualified leads they produce: $199, $399, $599, $799 or $1,199 every 4 weeks (13 payments a year, not 12). Which tier a territory falls in depends on how many qualified leads it produces — the number in the table above. Nothing else. A bigger territory costs more because it delivers more, and you can check the ratio yourself.

At a typical $1,000 gross profit on an installed system, every tier pays for itself at under a 1% close rate — fewer than one install per hundred addresses.

Sold once. If it is yours, nobody else is buying it

We sell a territory once. 23 of 23 are open. If yours is taken it is taken, and if it is yours, nobody else gets the same list from us. This page is the record — it changes when a territory does.

Your territory is here and it says “Ask” instead of a price button

That is deliberate, and the reason is in your favour. The price on this page comes from measured volume — the same ladder for everyone, published, not negotiated. For a few territories our own arithmetic says that price probably does not pay you back inside a year at a conservative close rate, and we would rather say so on a call than take a card and find out in month four.

Nothing is wrong with the data for those areas. The counts, the chemistry and the addresses are exactly what every other territory gets. What is thinner is the volume against the price, and whether that works depends on things this page cannot measure — what one install is worth to you, and how many of the cards we mail in your name turn into a call.

So: tell me which territory and what an install is worth to you, and I will do that arithmetic out loud with you. If it does not clear, I will say so.

Ask about this territory

Your area is not on this page

That is the likely outcome, and it is worth being straight about it. There are 23 of these and the country has rather more than 23 service areas. A territory only appears here once its state has been pulled, joined to groundwater chemistry and measured — and only if it clears 500 qualified leads a year.

What is not a reason: your state being difficult. The method is the same everywhere and it is published at /methodology.html — public well filings, joined to public water-quality measurements. What decides it is whether your state publishes its filings in a form worth pulling, and how much new drilling happens near you.

Tell me where you work and I will tell you the honest answer — whether it is buildable, roughly what it would carry, and whether it clears the floor. If it does not, I will say so rather than sell you a thin list.

Ask about your area

Counts come from each state’s own well records — Texas’s Submitted Driller’s Reports, Michigan’s Wellogic, Wisconsin’s Groundwater Retrieval Network, Minnesota’s Well Index and Florida’s water-management-district permit files — narrowed to newly completed domestic wells in groundwater at or above the softener threshold. Hardness comes from the Texas Water Development Board’s Groundwater Database in Texas and from the national Water Quality Portal (USGS and EPA) elsewhere. Landlord-owned (rental) properties are excluded only where a state publishes an owner mailing address — Texas, Minnesota and Lee County, Florida. Elsewhere they are still in the count, so those figures are an upper bound. Method: /methodology.html. Total across all territories: 31,431 qualified leads a year.
