Prairie Grove is a city in Washington County, Arkansas, United States. The population was 4,380 at the 2010 Census. It is part of the Fayetteville–Springdale–Rogers, AR-MO Metropolitan Statistical Area. Located here is the Prairie Grove Battlefield State Park. The park spans a large amount of land and contains a visitor center, museum, several monuments, a driving tour and a collection of period buildings and homes you can tour.
Prairie Grove was the site of the Battle of Prairie Grove during the American Civil War. Confederate forces under General Thomas C. Hindman attempted to prevent the juncture of two Federal forces under Generals James G. Blunt and Francis J. Herron. The result of the battle was a tactical stalemate which assured permanent Union control of northwest Arkansas. The battlefield is now a State Military Park. During Labor Day weekend in the fall, the park hosts the Clothesline Fair which is a typical southern style hometown celebration. Crafts vendors and artists from all over the nation descend on this southern town to display and sell their talents and wares.
The Natural Resources Defense Council released an issue paper stating between that 1997 and 2001, Prairie Grove was the center of a cluster of testicular cancer cases. No clear cause has been identified but the NRDC notes the town is near a closed nuclear reactor and a low-level radioactive landfill. Arsenic from industrialized chicken manure is another possible source. In 2004, residents sued one of the poultry farms and the poultry feed manufacturer for spreading contaminated manure throughout Prairie Grove. The lawsuit did not assign blame and the cause of the cancer cluster has never been definitively determined.
