University of Arizona Study Reveals Lingering Psychological Trauma from Tucson's Historic Water Contamination
A new study from the University of Arizona has found that one in three residents of Tucson's south side, who were exposed to industrial solvent-contaminated water decades ago, still report symptoms consistent with post-traumatic stress. The contamination, which involved industrial solvents leaking into groundwater, affected the area's drinking water for years before being addressed. Researchers surveyed 363 individuals, and among those who lived, worked, or attended school in the affected area before 1981, 34% met the screening threshold for post-traumatic stress. The symptoms reported included avoiding places that brought contamination to mind, experiencing sleep disturbances, or feeling isolated from others. The study, published in the Journal of Health Psychology, is a collaborative effort between the Department of Psychology and the Mel and Enid Zuckerman College of Public Health, led by Harrison Schmitt and senior author Daniel Sullivan.
