Is Alamogordo Water Hard? What Homeowners Should Know
Published 5 November 2026
Yes. The City of Alamogordo calls its tap water "very hard." In the city's 2025 Water Quality Report, hardness averaged 38 grains per gallon, or 652 parts per million, over 12 months. Hard water is not a health problem, but it does leave more scale on fixtures and means you use more soap and detergent.
Hard water is one of the first things new homeowners here notice, usually on the shower glass. Here is what the city's own reports say, and what it means for your house.
How hard is the water in Alamogordo?
These numbers are from the city's 2025 Water Quality Report, listed as 12 month running averages.
| Measure (2025) | Result |
|---|---|
| Hardness, grains per gallon | 38 gpg |
| Hardness, parts per million | 652 ppm |
| Calcium | 179 ppm |
| Magnesium | 51 ppm |
| pH | 7.41 |
Water softeners are usually set in grains per gallon, and the report notes that one grain per gallon equals 17.1 parts per million. On its water production FAQ page, the city says its water typically runs 34 to 39 grains of hardness per gallon, because of minerals such as calcium in the rock formations the water comes from.
Where does Alamogordo's water come from?
According to the 2025 report, the main supply is a network of spring compounds, infiltration galleries and stream diversions in Fresnal and La Luz Canyons. That water goes to the city's 188 million gallon raw water storage and treatment facility in La Luz, where it is filtered, disinfected and delivered by gravity to customers.
The city also runs twelve groundwater wells, which are usually brought online from April through mid September to add to the supply during high demand. For the bigger picture, see my post on Alamogordo's 40 year water plan.
Is Alamogordo tap water safe to drink?
The city says operators test water throughout the system to make sure it meets or exceeds federal and state drinking water standards, and that staff ran more than 2,775 drinking water tests in 2025. The detected contaminants table in the 2025 report lists no violations.
The city also says there are no harmful health effects from the minerals that make water hard. It does not add fluoride, so any fluoride in the water comes naturally from the source water. If you want a paper copy of the report, the city's Water Quality Reports page lists how to ask for one.
What does hard water mean for my home?
The city's FAQ puts it simply: hard water causes more scale buildup, and you need more soap and detergent. In everyday life, that tends to show up as white spots on glass and fixtures and mineral buildup around faucets and showerheads.
The city also says you do not need to filter the water coming into your house. If you choose to install a filter, it notes that filters have to be maintained, because a neglected filter can make your water quality worse.
Who do I call about water taste, color or pressure?
During business hours, 7 a.m. to 3:30 p.m., call the city's Water Treatment Division at (575) 437-5991. After hours, call the city's dispatch center at (575) 439-4300.
If your water looks cloudy, the city says it is usually tiny air bubbles that rise and clear if you let a glass sit, and it happens more often in winter. Discolored water can follow hydrant testing or a main break as iron sediment is stirred up. The city says that water is safe to drink, but the iron can stain laundry. My post on hydrant flow testing explains when that work happens.
One seasonal note: the city's outdoor watering schedule runs from May 1 through November 1, so it has just ended for the year.
What does this mean for buyers and sellers?
Hard water is normal here, so it is not a red flag on any one house. If you are buying, it is worth asking whether the home has a water softener or filter and how it has been maintained, and looking at faucets and the water heater for buildup.
If you are selling, cleaning scale off glass and fixtures before photos makes a home look fresher. This applies to homes on City of Alamogordo water. If a home is on a private well or another water system, ask that provider for its own report. You can read more about getting a home ready on my sell your home page.
