How Much Does a Well Water Test Cost? (2026 Pricing Guide)

A well water test costs anywhere from $13 for hardware-store test strips to $400 or more for a comprehensive certified lab panel, and the pricing in this industry is unusually hard to pin down. Here is what each kind of test costs in 2026, what the price leaves out, and the fees that are not on the sticker. The one most of my customers order is our 53-contaminant well water test: $199, with shipping both ways included.

Well water test prices by type

The cheapest test depends on how many things you need checked. For one or two items, a county lab costs least; for a full panel, a mail-in kit does. Here is each option with its 2026 price and what you get for it.

Most of my customers order the 53-contaminant test. When someone needs results fast, I tell them to call a local water testing lab and have them come out and take the sample. It gets done a lot faster; it just costs more. A lab that comes to your house and picks up a sample will charge you anywhere from $300 to $1,000, depending on how many contaminants you want tested.

What the $199 well water test covers

One sample covers 53 contaminants, bacteria included, and the price covers shipping both ways. The 53 are E. coli and total coliform bacteria; 18 heavy and trace metals, including arsenic, lead, mercury and uranium; 11 metals and minerals, including iron, manganese and calcium; pH, hardness, alkalinity, total dissolved solids, turbidity and conductivity; and 8 inorganics, including nitrate, nitrite, chloride, fluoride and sulfate. Eight of the 53 are values the lab calculates from the others. That list includes all four tests the EPA says to run on a private well every year.

An independent lab in SimpleLab's network runs the test, and the lab is ISO/IEC 17025-accredited. SimpleLab also sells its own kits under the Tap Score name. The kit ships to you free by FedEx with a prepaid FedEx return label in the box. Results come back about 5 business days after the lab receives the sample; from the day you order to the results in your inbox is usually 2 to 4 weeks.

A man who called me in August had heard the lab would charge him $1,500 on top of the kit. "So the whole cost to me would be $199?" he asked. My answer: "$199. The kit comes to you. You follow the instructions, send it out in the prepaid envelope. It goes to a lab, and you get the results back within 5 business days from the time the lab receives it."

When a university asked me about a discount on 85 kits, this is what I told them: "there's hardly any profit in them. We just do it as a service to our customers, so they get the right equipment the first time."

Tests the $199 kit skips

The 53 do not include hydrogen sulfide, radon, VOCs, PFAS, pesticides, tannins or iron bacteria. Most of those are separate lab tests:

If you need the VOCs too, the advanced well water test runs the same 53 plus the 60 VOCs on one sample for $329, which is $39 less than buying the two separately. Wisconsin's state lab charges $111 for radon and $141 for a VOC screen, a little less than ours.

What a county or state lab charges

A county or state lab charges for each test, so the cost climbs with every item you add. In Wake County, North Carolina, a coliform bacteria test is $25 and the full inorganic panel is $50, and you can take both samples yourself: $75 for the two. If the county comes out to collect, add a $50 trip fee. VOCs and pesticides there have to be collected by a professional, as part of the $175 First Timer's Package plus the trip fee.

If all you want is the yearly bacteria check, the county is cheaper than us. Our bacteria-only test is $139; Wake County's is $25.

The full list is where it adds up. Here is what Wisconsin's state lab charges, item by item, for seven things that are all on the $199 test (prices effective July 1, 2026):

The same lab's homeowner package is $450 and adds a VOC screen and an atrazine screen. Here in Maryland, local labs are crazy expensive, even for a basic test: about $300. To find the lab that serves your county, see where to get your water tested.

Extra fees on top of the price

Some kits charge return shipping separately, and you pay it the day you mail the sample. Here is what four mail-in kits cost once the sample is on its way back:

Two other fees catch people. Rush results cost about double: Wisconsin's state lab doubles the price for a RUSH sample, and Tap Score's rush Essential kit is $429 instead of $209. And when a county sends someone to take the sample, there is a trip fee on top of the test ($50 in Wake County).

What a free in-home water test checks

A dealer's free test, like Culligan's, checks only the basics, such as hardness, pH and iron. Culligan's own pages say its free test checks hardness, pH, chlorine, total dissolved solids, hydrogen sulfide and iron, with results in 30 minutes or less, followed by "a no-cost, no-obligation estimate of any recommended water solutions." For lead, arsenic, bacteria or PFAS, it recommends more testing at its lab.

Are those tests accurate? The test kits we use in the industry are pretty accurate. They're not as accurate as the independent lab test, but they're close. But there are some shady characters, and people will manipulate the in-home test kit to get the results they want so they can sell you some equipment.

They also have a ceiling. Someone who called me in June had a Culligan rep test the iron, and "his checked up to 5 parts per million, and mine was past that." So the test could not say how much iron was there, and the number decides what equipment you need.
