Emergency Crime Scene and Biohazard Cleanup in Caseyville, IL

Caseyville is a village in St. Clair County that was founded in 1849 by the Illinois Coal Company and named for Zadok Casey, a former U.S. Representative and Lieutenant Governor of Illinois who was one of the company's partners.

Wealthy Frenchman Charles Harbour built a fine brick house and a steam sawmill at the site in 1845, a few years before the town was formally laid out.

Coal was the reason Caseyville exists - mining began around its founding, and in 1851 the coal company built a railroad to nearby Brooklyn, Illinois just to haul its coal out.

The settlement grew from only about 40 people in 1850 to roughly 150 a year later and about 800 by 1881, and the village was officially incorporated in May 1869.

Caseyville's first post office opened in 1856, its first school was built in 1872, and its first church followed in 1879.

The 2020 census counted 4,400 people in Caseyville, up from 4,245 in 2010, spread across roughly 1,500 households in Census Bureau survey estimates.

Caseyville covers about 7.2 square miles, an unusually large area for a village of its population, and a little over 2 percent of that area is water.

The village sits in the Metro East region of the St. Louis metropolitan area, just east of the Mississippi River bluffs, with Canteen Creek draining the northern part of the surrounding township.

Most Caseyville students are served by Collinsville Community Unit School District 10, tying the old coal village to the neighboring city of Collinsville.

Caseyville's population peaked at just over 4,400 in the 1990 census era and again in 2020, after dipping during the early 2000s - an unusually stable headcount for a former mining town.
