Whole House Water Softeners in Tioga

Federal records list the City of Tioga as a groundwater system with 649 service connections serving about 938 people, with active wells on Mitchell Street, at the east pump station and east of West Main Street near Sherman Street, an inactive well at the west pump station and a plugged one. The state well index gives the depths: the city's Well 3, drilled in 1971, reaches 1,500 feet, and Well 4, drilled in 2003, reaches 1,482 feet, both in the Antlers Sand, while the town's 1936 municipal well stopped at 215 feet in the Woodbine and is no longer used. The U.S. Geological Survey's study of Grayson County's groundwater notes that the saturated Trinity sand is more than 600 feet thick about three miles east of Tioga and over 500 feet thick in a band from Tioga to Gunter, which is why deep, productive wells are possible here.

What those wells bring up is not the hard water of a North Texas lake. The Water Development Board sampled Well 3 in July 2023 and found 192 mg/L of sodium, 338 mg/L of total alkalinity and 481.5 mg/L of total dissolved solids; calcium was 0.99 mg/L and magnesium 0.3. An April 2019 sample read 179 sodium, 333 alkalinity and 462.3 dissolved solids, and a November 2004 sample from Well 4 read 198 sodium and 513 dissolved solids. The Geological Survey's county report describes the same thing in words: the Trinity group in Grayson County generally yields soft water with a high sodium bicarbonate content, and of 35 hardness determinations it collected only 6 exceeded 60 ppm. The state's 2007 groundwater study for the region says Trinity water is harder on the outcrop and softer downdip, with more dissolved solids. Tioga's own 2025 report is a scanned image whose tables could not be read in full, and no printed hardness result for the city has been found, so this page gives none.

At a Tioga tap the minerals are there, as the dissolved-solids figures show, but they are mostly sodium and bicarbonate rather than the calcium and magnesium that scale a water heater. Which well is running, and whether the city blends them, can shift sodium and alkalinity between the Well 3 and Well 4 readings above, and the town's wells have been sampled by the state often enough to show that the chemistry holds steady from one decade to the next. A conventional softener exchanges calcium and magnesium for more sodium, so where the state's well samples show close to 200 mg/L of sodium already, the decision should rest on a measured hardness, not an assumption. The free water test measures it at your tap, and a softener, if one is warranted, is sized to that result rather than to what the aquifer is said to be.
