Duncan, Oklahoma boasts city lakes, historical locations and the flowers of Crape- myrtle. It sits just a smidgin southeast of Lawton with a wide open area to its east. From 1919 to 1961 Duncan was the home to Halliburton, and recently the company discovered it may have left some things behind when it moved corporate offices to Houston and Dubai.
Perchlorate has found its way into 18 water wells there on the city's north side. It is thought the perchlorate came from Halliburton's previous work there of removing and burning spent missile fuel from missile casings. The company so far is supplying bottled water to residents and a temporary water supply system where needed. It is also reimbursing residents for health screening costs and is continuing to investigate the problem.
