You scrub the white crust off your faucets, pull cloudy glasses out of the dishwasher, and wonder why your skin feels tight after every shower. If you live in Midland, you already suspect the answer is in your water. What you may not know is just how high Midland water hardness actually runs, or why the report the city mails out every year never seems to mention it. Midland water hardness is the one number that report leaves out.
Here's the short version. By the standard the U.S. Geological Survey uses, anything above 180 milligrams per liter of dissolved calcium and magnesium counts as "very hard." Independent water quality databases that compile public testing data consistently place Midland tap water around 17 to 19 grains per gallon, which works out to roughly 290 to 330 milligrams per liter. That is not just hard water. Midland water hardness sits in a range most of the country never encounters, well above the very hard threshold.
The annual report from the city is still worth reading, because it tells you important things about safety that hardness numbers don't. This guide walks you through both: what the report covers, what it leaves out, and how to get a Midland water hardness number for your own home.
If you'd rather skip the homework, PureSource offers free in-home water testing for hardness, chlorine, total dissolved solids, and more. It's a quick, no-pressure way to see exactly what's coming out of your taps before you decide whether anything needs fixing.
Water hardness is a measure of dissolved calcium and magnesium. The USGS classifies water as soft up to 60 mg/L, moderately hard from 61 to 120, hard from 121 to 180, and very hard above 180 mg/L. By that scale, Midland water hardness lands well past the top category.
You'll see two units used almost interchangeably, and the conversion trips people up. Lab reports and government sources usually use milligrams per liter (mg/L), which is the same as parts per million. The water treatment industry usually talks in grains per gallon (gpg). One grain per gallon equals about 17.1 mg/L. To convert, divide the mg/L figure by 17.1. A reading of 300 mg/L, for example, is about 17.5 gpg. Once you can flip between the two, every hardness chart on the internet suddenly makes sense, and you can sanity-check any Midland water hardness figure you get quoted.
For context, a 17 to 19 gpg reading means every gallon of Permian Basin water moving through your home carries roughly a gram of dissolved rock. Multiply that by the tens of thousands of gallons a typical household uses each year and you can see why West Texas water heaters, dishwashers, and fixtures wear out faster than the ones in soft-water cities. That wear is what Midland water hardness actually costs you.
Every community water system in the country must publish a Consumer Confidence Report by July 1 each year, and Midland is no exception. You can find the current City of Midland water quality report on the city's website under Reports and Notices. Here's how to read it like a pro instead of skimming past the tables, and why you shouldn't expect a Midland water hardness figure in any of them.
The report tells you where your water begins. Midland's supply blends surface water purchased through the Colorado River Municipal Water District, drawn from O.H. Ivie Reservoir, E.V. Spence Reservoir, and Lake J.B. Thomas, with groundwater from the city's own well fields: the Paul Davis field in Midland County, tapping the Ogallala and Pecos Valley aquifers, plus the T-Bar and Clearwater fields in Winkler and Loving Counties, tapping the Pecos Aquifer. That mix matters, because groundwater picks up dissolved minerals as it moves through soil and rock, which is a big part of why Permian Basin water carries so much calcium and magnesium by the time it reaches your tap. Geology is the origin of Midland water hardness.
Most of the report is tables, and three terms unlock them. MCL is the Maximum Contaminant Level, the highest amount of a substance legally allowed in drinking water. MCLG is the goal level, the amount below which there's no known health risk. When a detected level exceeds an MCL, the report has to flag it, and the violation column beside every row is where you look. In Midland's 2025 report that column reads "N" the whole way down, and the report states outright that the city had no violations during 2025. What the tables do show is how close a few numbers run to their limits. Total trihalomethanes, a byproduct of disinfection, reached a locational running annual average of 76 parts per billion at one Midland sampling site against an 80 ppb maximum. In compliance, but not with much room, and worth knowing if you are weighing a carbon filter. What none of those tables will ever tell you is your Midland water hardness.
The city disinfects with chloramine, and the 2025 report lists an average residual of 2.44 ppm in the distribution system against a maximum allowed level of 4. That residual protects you from bacteria, but it's also part of why tap water can taste and smell like a swimming pool. A carbon filtration step at home addresses the taste without undoing the protection in the pipes.
Here's the part that surprises almost everyone. Read the city's 2025 report cover to cover and you won't find the word hardness anywhere in it, or calcium, or magnesium, or a single figure in grains per gallon. That's not the city hiding anything. Hardness simply isn't a regulated contaminant, because calcium and magnesium don't threaten your health. The EPA only treats minerals like these as aesthetic concerns, so they never appear in the violation tables at all. Midland water hardness is a comfort and cost problem, not a health one.
The practical takeaway: your city water quality report answers "is my water safe," not "how hard is my water." Scale on your fixtures, shortened appliance life, dry skin, and stiff laundry are real problems, but they're your problems to solve, not the utility's. The only way to know your home's exact number is to test at your own tap, which also captures anything your plumbing adds along the way. A tap test is the only real Midland water hardness measurement there is.
Once you know where Midland water hardness lands at your own tap, the fix is straightforward. A water softener removes hardness at the source, swapping calcium and magnesium for sodium or potassium ions through ion exchange. Because Permian Basin water carries such a heavy mineral load, sizing matters, and sizing starts with your own Midland water hardness number rather than a regional average. A system built for 8 gpg city water elsewhere won't keep up here, which is why PureSource installs and maintains water softeners specifically engineered for local conditions, backed by salt delivery and ongoing service across Midland, Odessa, and the surrounding Permian Basin.
Softening handles the minerals, but it doesn't address chlorine taste or dissolved solids in your drinking water. That's where whole-home filtration and reverse osmosis systems come in. An RO unit at the kitchen sink strips out most of what softeners leave behind, giving you clean, great-tasting water for drinking and cooking. The 2025 report's unregulated monitoring results make that case better than we could: lithium averaged 50.7 ppb and four PFAS compounds turned up at trace levels. Neither is a violation, and the report says so plainly, but neither is touched by a softener either. Midland water hardness is one problem; what dissolves alongside it is another. Many local homeowners pair the two: a softener protecting the whole house and RO polishing the water the family actually drinks. Together they handle Midland water hardness and everything it leaves behind.
Generally yes. The city treats and tests its supply continuously, and the 2025 city water quality report recorded no violations for the year. It also carries EPA's own note that while Midland's water meets the arsenic standard, it does contain low levels of arsenic, measured at a high of 9.19 ppb against a 10 ppb limit. Safety and quality aren't the same thing, though. Water can meet every federal standard and still taste flat, smell of chlorine, and coat your kettle in scale.
Test strips from the hardware store give a rough reading. For a precise number covering hardness, chlorine, metals, and total dissolved solids, schedule a free test with a local water professional who can sample straight from your taps.
Not by itself. Softening changes feel more than flavor. Pairing a softener with carbon filtration or reverse osmosis is what transforms taste.
