Well inspection when you buy or sell a home around Springfield

A standard home inspection usually stops at the kitchen faucet. On a house outside city water, the well, the pump hundreds of feet down, the pressure tank and the water itself are a separate system, and a failed one can cost more than a new roof. A well inspection before closing tells a buyer what they're getting and gives a seller fewer surprises in negotiations. Missouri doesn't require one statewide, so it's up to the buyer, the lender or a local rule (Jasper County has one, covered below).

What a well inspection covers

HomeGuide's well inspection cost guide (July 2025) describes a typical inspection as:

• A look at the casing, cap, gaskets, seals, vents, electrical conduit and wellhead, and at the surroundings for anything that could contaminate the water.
• Tests of the mechanical parts: pump motor, gauges, pressure relief valve and piping.
• Tests of the electrical side: control box, capacitors and connections.
• A flow test of the system's output and how the pump motor performs.
• Water samples, if lab testing is included, and a written report with recommended repairs.

The same guide makes a point buyers should hear: an inspection does not evaluate the water table, so it can't promise the well will keep producing for decades. A flow test shows what the well and pump delivered on the day, and a dry summer can tell a different story (see how a well that's running dry behaves).

What to check on an Ozarks well in particular

• The wellhead against Missouri's code. Rule 10 CSR 23-3.050 wants the casing top at least a foot above grade with a tight, vented, screened cap, and a pitless adapter where the line leaves the casing underground. A buried casing, an old-style loose cap or a well pit is worth a note in the report, because in karst ground surface water reaches an open casing quickly. Our well service guide covers the details.
• The pump's electrical health. A tech with an amp clamp and a megohmmeter can read the motor and cable from the surface, the same tests used in pump repair, and get a fair idea of whether a 20-year-old pump has years or weeks left.
• The pressure tank. A waterlogged tank that short-cycles the pump is a cheap fix that hides an expensive future one. Ask for the air charge and the switch settings in the report (pressure tank sizing).
• The well record. Missouri DNR's Missouri Geological Survey keeps records for many wells; its WISDIM map lets you search for wells and installation records. A record shows depth and casing length. No record on an older house is common, but the seller may have pump receipts that show the setting depth.
• Abandoned wells on the property. Old farm wells and cisterns turn up on acreage. An unplugged old well is a safety hazard and a direct path for contamination to the aquifer the house well draws from; here's how Missouri requires old wells to be plugged.

Water testing for a sale

At minimum, test for total coliform bacteria, E. coli and nitrate. Around Springfield that's inexpensive through the county health departments; our county-by-county testing guide lists the labs, fees and the Monday-to-Thursday drop-off windows, which matter when you're working against a closing date. HomeGuide puts private-lab packages at $130 to $200 for a basic panel (bacteria, metals and minerals, lead, nitrate) and $220 to $450 for an advanced one that adds volatile organic compounds, which is worth considering near the solvent plume northwest of Springfield described on our testing page.

Joplin area: lead and cadmium at transfer

In Jasper County the test isn't optional. The county's environmental ordinance makes the water from a private well subject to a lead and cadmium test whenever the property changes hands, with the sample drawn by a sampler certified by Missouri DNR. If you're buying around Joplin, Carthage or Webb City, put that test and its timing in the contract.

What it costs

HomeGuide notes that wells deeper than about 500 feet can cost more to inspect because most sounding equipment only reaches that far, and that some companies add a travel fee of $1 to $2 a mile, which adds up on rural Polk or Webster County roads. These are national figures; the inspector sets the price.

Questions to ask before you hire

• Will you run a flow test, and for how long?
• Will you read the pump's amps and the cable's insulation from the surface?
• Do you collect the water sample, and which lab runs it?
• If something fails, can you quote the repair, so it can go into the negotiation?

If the inspection turns up a worn pump or a bad tank, the repair is often quick; see well pump replacement for what's in that quote. Call and we'll connect you with a licensed local pump installer.
