Biohazard Cleanup Near East Eureka Eureka, TX

Eureka is a small city in Navarro County in north-central Texas, located at the junction of U.S. Highway 287 and Farm to Market Road 637, about 11 miles southeast of the county seat of Corsicana.

The community grew up around Dunn's School, a log schoolhouse built just before the Civil War.

Eureka got its name at an 1870 meeting of the local Grange, when residents chose the name as they applied for a post office that opened in the home of P. Anderson.

By 1885 Eureka had several steam-powered gristmills and cotton gins, two churches, and a district school, though its population was only about 25 people.

In 1906 Eureka operated three schools — two for White students, with 85 enrolled, and one for Black students, with 61 enrolled — a snapshot of segregated rural Texas education.

The town had about 100 residents in 1914 and, by the mid-1930s, supported a school and six businesses; after World War II its school was consolidated with nearby Mildred.

The population was 313 at the 2020 census, up from 307 in 2010 and just below the 340 counted in 2000, when the census recorded 122 households and 101 families in the city.

Eureka's population has stayed in the low hundreds for a century — 233 in 1980 and 242 in 1990 — keeping it one of the smallest incorporated cities in Navarro County.
