Well drilling cost around Springfield: what goes into a new-well quote

A new well is priced mostly by the foot, and around Springfield the number of feet is set less by how much water you need than by the rock under your lot and the casing Missouri requires. Two neighbors can get quotes thousands of dollars apart for the same house. This page lays out the national price ranges, the state rules that decide how much casing goes in the hole here, and the lines you should expect to see on a well drilling quote, so you can compare bids from licensed drillers.

National well drilling price ranges

We don't set prices; the driller does. For a starting point, HomeGuide's well drilling cost guide (July 2025, built from contractor estimates) gives these national figures:

HomeGuide also notes that rocky ground, remote sites and a deep water table push the per-foot price up, with some owners paying $100 a foot or more. Ozarks wells check most of those boxes: they're drilled through limestone and dolomite, and the deep ones go several hundred feet. Treat the national table as a way to read a quote, not as a Springfield price.

Why casing depth drives the price here

Casing is the pipe that lines the top of the hole and seals out shallow water. Missouri's well construction rule 10 CSR 23-3.090 (Drilling Areas) splits the state into areas with different minimum casing, and the Springfield region sits across three of them:

• Area 9: Greene and parts of Christian County. The rule describes it as rapid urbanization in a sensitive geologic setting. The shallow Springfield Plateau aquifer and the deep Ozark aquifer are separated (not everywhere evenly) by a low-permeability layer called the Ozark Confining Unit. A bedrock well here must be cased at least 10 feet below the Ozark Confining Unit, and the grout has to seal the whole confining unit plus at least the lowest 30 feet of casing. So casing length isn't a fixed number; it follows the depth of that layer under your lot. Plastic casing needs a borehole at least 4 inches wider than the casing; steel needs 2.
• Area 11: Jasper and Newton County. Parts of the shallow aquifer around Joplin are contaminated with lead, cadmium or solvents such as TCE. Outside the mapped impact areas a well may stay in the upper aquifer if it doesn't penetrate the confining unit (with at least 80 feet of casing, 30 into solid rock), or be cased and sealed through the confining unit to draw only from the deep aquifer. New upper-aquifer wells come with sampling requirements.
• Area 1: much of the rest of southwest Missouri. At least 80 feet of casing, extending at least 30 feet into solid bedrock, with the lowest 30 feet grouted. The rule's own example: hit 60 feet of soil and broken rock before solid bedrock and you need 90 feet of casing.

Lots near the big lakes are another case. Area 8 covers a quarter-mile buffer around lakes including Stockton, Pomme de Terre, Table Rock and Truman, and there the casing has to go 50 feet below the deepest point of the lake within a quarter mile, so a lake lot can need far more casing than a pasture a few miles away. The rule makes it the drilling contractor's job to work out which area a well is in; ask them to say which one, and how many feet of casing and grout they're pricing.

Steel or plastic casing

The construction rule (10 CSR 23-3.030) sets minimums for both: steel casing at 0.188-inch wall (6-inch steel weighs about 13 pounds a foot), and plastic at SDR 26 or schedule 40 in 4- to 6-inch sizes. Casing has to be new, joints watertight, and grout placed by an approved method. With HomeGuide's ranges of $7 to $11 a foot for PVC against $30 or more for steel, a quote's casing line can swing by thousands of dollars on a deep Area 9 well, so ask which one is priced and why.

How deep are wells around Springfield?

There's no single answer, and anyone who quotes a depth before drilling is guessing. U.S. Geological Survey records for wells in the Springfield area show the range: one well in the shallow Osagean limestone of the Springfield Plateau aquifer is 80 feet deep, one finished in the Cotter Dolomite of the Ozark aquifer is 426 feet, and one in the deeper Roubidoux Formation is 685 feet. Missouri DNR's Missouri Geological Survey keeps well records you can search through its Well Installation Section Drilling Information Map (WISDIM), so a driller can look at logs from wells near you before bidding. Those logs are the best predictor of your depth, casing length and yield.

The same state records give a better picture of modern domestic wells than any single example. In DNR's water well database (pulled October 2026), the 432 domestic wells with a Springfield site address have a median depth of 545 feet (middle half 470 to 605), a median static water level of 180 feet and a median of 140 feet of casing, mostly steel. Wells get shallower to the north: Bolivar's median is 345 feet and Marshfield's 385, while Nixa's is 605. Town-by-town numbers are on the town pages, for example Bolivar and Nixa.

Lines to expect on a new-well quote

One line in Missouri's certification rule is worth knowing before you sign: certifying a well "does not guarantee or imply that the well will produce potable or usable quantities of water." Ask each driller how they bill if the hole comes up dry or low-yield, and whether going deeper is priced at the same per-foot rate. A dry hole isn't left open: Missouri requires it to be plugged within 30 days.

New well or new pump?

Plenty of people price a new well when the existing one only needs a pump, a tank or a switch. If you have water some of the time, or the pump runs but pressure is weak, start with the no-water checklist and pump repair. A pump pull and a casing check cost a fraction of drilling, and a tech can tell you whether the well itself has failed.
