Self-Reported Consumption of Bottled Water v. Tap Water in Appalachian and Non-Appalachian Kentucky.

Introduction: Quantitative studies on drinking water perceptions in Appalachia are limited. High-profile water infrastructure failures in the U.S. and Eastern Kentucky, coupled with human-made and natural disasters in the Appalachian Region, have likely impacted opinions regarding tap water.

Purpose: To use existing unexplored data to describe baseline tap water v. bottled water consumption in Kentucky.

Methods: Telephone-based cross-sectional data were obtained from the 2013 Kentucky Health Issues Poll (KHIP) directed by the Foundation for a Healthy Kentucky. Among many items in KHIP, self-reported consumption of bottled water over tap water, reasons for bottled water use, and demographic data were obtained.

Results: Among Appalachian (n=356) and non-Appalachian (n=1,125) Kentucky respondents, a significantly higher frequency of Appalachian Kentuckians reported drinking bottled water more often than tap water relative to non-Appalachian Kentuckians (57% v. 34%; X² p < 0.001). Appalachian residency significantly predicted bottled water consumption in simple and multivariable logistic regression adjusted for significant covariates (i.e., age, sex, and race). Among persons consuming bottled water more than tap water, Appalachian Kentuckians reported significantly more concerns regarding tap water taste or smell (p = 0.005) and safety (p = 0.008) than non-Appalachians.

Implications: These results from 2013 data pre-date headline news items related to public water and likely underestimate current bottled water preferences. New data are needed, and these results warrant further investigation into tap water aesthetics in Appalachia, bottled water consumption impacts on personal finances, and approaches to build public trust for public drinking water among multiple populations including Appalachian Kentuckians.
