HOW HARD IS THE COLONY’S WATER?

12 ppm. That is 0.7 grains per gallon.
The Colony water quality report lists a total hardness of 12 ppm. On the USGS hardness scale that is soft water. The 12 ppm figure is The Colony's own well water; homes on Dallas or Plano water get a harder supply, and the blend shifts by area and season.
COMMON SIGNS OF HARD WATER
What hard water looks like at home.
At about 0.7 grains per gallon, The Colony’s figure is soft water, so these signs point to a harder share of the supply or to the day’s blend rather than to the figure. Three or more of them, and the free water test says what is at your tap.
Cloudy glassware and white spots the dishwasher cannot rinse off: the minerals that dry out of each gallon of harder water.
The white crust is limescale. It narrows spray holes and seizes aerators and valves.
Calcium and magnesium react with soap before it foams: more soap, and scum on tubs and shower doors.
The same soap curd settles on skin and hair and does not rinse away.
Minerals bind to fabric and detergent. Towels come out stiff, whites go grey, colors fade sooner.
Scale coats heating elements and clogs small valves, so appliances work harder and fail sooner.
THE COLONY’S WATER, BY HARDNESS
Soft deep-well water at 12 ppm, harder Dallas and Plano water in parts of town
The Colony's 2024 water quality report prints its mineral table in three columns, one for the city's own wells, one for Dallas Water Utilities and one for Plano, and the first column is where this page's figure comes from. The report says the city owns and runs the system inside its limits whatever the supplier, and that its own state-licensed operators monitor and test the water. It also describes the three waters' origins. The wells draw on the Trinity Sands and the Paluxy, deep sandstone aquifers. Dallas water comes from a utility the report says draws on seven sources: Lewisville, Ray Roberts, Ray Hubbard, Tawakoni, Fork, the Elm Fork of the Trinity and Grapevine. Plano water, which the report places in the part of Austin Ranch south of State Highway 121 and east of the MKT rail line out to the eastern city limit, is North Texas Municipal Water District water from Lavon, Jim Chapman and Texoma.
Hardness in the wells column is 12.0 ppm, soft on any scale, about 0.7 grains per gallon, and the rest of the column explains why. Calcium is 3.53 ppm and magnesium 0.785 ppm, next to nothing, while sodium is 354.0 ppm, total alkalinity 319.0 ppm and dissolved solids 915.0 ppm, with a pH of 8.5 to 8.7. That is the signature of deep sandstone water: plenty of dissolved mineral, but the calcium and magnesium that make water hard have been exchanged for sodium on the long path underground, and the state's aquifer notes agree that Trinity water is very hard only where the sands reach the surface and gains dissolved solids with depth. The Plano column is the reverse: hardness 202 ppm on a range of 105 to 202, calcium 35.4 to 66.5 ppm, magnesium 5.88 to 9.84 ppm, sodium 35.5 to 88.7 ppm, dissolved solids 207 to 509 ppm, district lake water that is very hard at its peak. The Dallas column prints no secondary data, but a December 2023 Dallas memorandum states the city's hardness runs 120 to 155 mg/L as CaCO3, moderately hard to hard, from lakes including Ray Roberts and Lewisville treated at its Elm Fork and Bachman plants.
Which column you live in decides your water. Homes on the well supply can see water at 12 ppm that needs no softening; homes in the Austin Ranch pocket on Plano water can see over 200 ppm; homes on Dallas water sit between, and because the city moves several sources through one system, many addresses see a mix that shifts with demand and season. The 12 ppm figure on this page is a well-water figure, not a citywide one. The report answers a question residents ask about milky water, dissolved air under pressure rather than minerals, but it does not map sources to streets, so the only way to know your own number is to measure it. The free water test gives it, and if your tap turns out to carry Plano or Dallas water, size the softener for the top of that range, about 12 grains per gallon.

HOW A SOFTENER WORKS
Ion exchange, salt and regeneration.
One tank of resin, one tank of salt, and a valve that runs the cycle.
Resin beads hold sodium ions. Calcium and magnesium swap onto the beads as water passes, and the water leaves at close to zero grains.
When the beads fill up, brine from the salt tank rinses the hardness to the drain and reloads the sodium, metered by the gallons you use.
Calcium, magnesium and a little dissolved iron. Not chlorine, chloramine, PFAS, lead or taste: that is a filter’s job, so see whole house water filtration for The Colony, and a reverse osmosis tap or bottled water delivery for drinking water.
A salt-free water conditioner turns hardness into crystals that stay in the water instead of on heaters and pipes: no salt, no drain, less scale, no relief for soap and skin.
HARDNESS QUESTIONS, ANSWERED
The hard water FAQ for The Colony.
Is The Colony’s water hard?
It depends on the source at your address. The Colony's own wells tested at 12 ppm in 2024, soft, about 0.7 grains per gallon, with 354 ppm sodium. Plano water in part of Austin Ranch printed 105 to 202 ppm and Dallas states 120 to 155 mg/L, so taps on purchased water are moderately hard to very hard. The free water test tells you which you have.
Is hard water safe to drink?
Yes. Hardness is calcium and magnesium, minerals with no federal drinking-water limit. It is a plumbing, appliance, soap and skin problem, not a health one.
Does a softener make my water salty?
No. The salt goes down the drain at regeneration; the water carries a little sodium in proportion to the hardness removed, which a reverse osmosis tap removes again.
THE SOURCE MATTERS
Where the number comes from.
Each figure is read from the document linked beside it, in its own units and period. A missing result stays missing; a range stays a range.
