What Makes Lufkin's Water Unique?
Local geology and source profile
Lufkin, Texas, the Angelina County seat — a major east Texas Piney Woods city (Lufkin is the largest city in the east Texas Piney Woods — the Angelina County seat and commercial center of the four-county Deep East Texas region), home of the Ellen Trout Zoo (a free admission municipal zoo — one of the unique municipal amenities in east Texas), a major east Texas forestry, manufacturing, and healthcare center, home of Angelina College and Lufkin Industries (formerly a major oilfield equipment and pipe manufacturer), and a diverse Angelina County community — draws its municipal water supply from Lake Sam Rayburn (Angelina River) via the City of Lufkin Water Division. Water hardness in Lufkin measures 422.5 mg/L — classified as extremely hard — one of the hardest municipal water supplies in the US.
Lufkin's extremely hard supply reflects the east Texas Eocene Gulf Coastal Plain's highly calcareous geology. The Angelina River watershed at Lake Sam Rayburn drains: the Eocene Claiborne Group (Sparta, Weches, Queen City, and Reklaw Formations — highly calcareous marine clay, sand, and glauconite of the east Texas Eocene Coastal Plain with significant dissolved calcium carbonate); the Eocene Wilcox Group (highly calcareous lignite-bearing Eocene marine sediment); and the Quaternary calcareous alluvial deposits of the Angelina River. City of Lufkin applies limited lime softening, producing the extreme 422.5 mg/L.
At 422.5 mg/L, Lufkin residents face extremely severe hard water challenges. Water softeners are essentially a necessity. City of Lufkin Water Division consistently delivers water meeting all Texas TCEQ and EPA Safe Drinking Water Act requirements.
