What Makes Mount Pleasant's Water Unique?
Local geology and source profile
Mount Pleasant, Texas, in Titus County — the Titus County seat adjacent to Pittsburg and Daingerfield on the Big Cypress Creek in northeast Texas — receives its municipal water from the Mount Pleasant Water Division, drawing from Lake Cypress Springs (Big Cypress Creek, Titus County) through the northeast Texas water treatment system.
The extremely hard 345.5 mg/L hardness and very high TDS of 1,000.4 mg/L make Mount Pleasant one of the hardest water supplies in the USA — consistent with the east Texas Big Cypress watershed's intense calcareous and evaporitic drainage. Lake Cypress Springs (Big Cypress Creek) drains the Cretaceous Eagle Ford Formation (calcareous chalk-marl — very hard), Eocene Wilcox Group (calcareous shale — additional hardness), and upstream Permian Wichita Group evaporitic redbeds (gypsum and halite — major TDS contributor from the Red River-Permian Basin upland input). The cumulative calcareous and evaporitic northeast Texas loading produces the extreme Mount Pleasant hardness and TDS.
At 345.5 mg/L with TDS 1,000, Mount Pleasant's water is extremely hard. A water softener is absolutely essential. Scale forms immediately on all surfaces, appliance lifespans are critically shortened, and water heaters fail within 2 years without treatment. The PFAS level of 10.4 ppt warrants a certified reverse osmosis drinking water filter — the northeast Texas industrial corridor and the Big Cypress Creek PFAS complex contribute to Mount Pleasant's elevated readings.
