5 - Trust in Tap: Improving Water Perceptions to Support Community Health and Prevent Chronic Disease

Abstract:

Objectives: This study examined the influence of tap water quality (TWQ) perceptions, primary drinking water source (PDWS), and beverage consumption behaviors, including tap water (TW), bottled water (BW), and sugar-sweetened beverages (SSBs), in a rural California community. It explores how TWQ perceptions affect drinking behaviors and overall public health.

Methods: A cross-sectional survey of 141 adults in Sonoma County, California, assessed TWQ perceptions, organoleptic concerns, demographic characteristics, and beverage consumption. Multivariable logistic and ordinal regression analyses identified predictors of PDWS, home water treatment device use, and beverage consumption.

Results: Trust in TW significantly increased its likelihood as the PDWS (OR = 4.2, p < 0.001). The presence of home water treatment devices strongly encouraged TW use (AOR = 26.0, p < 0.001), while Spanish-speaking participants were less likely to use filtration devices (AOR = 0.32, p = 0.019). Negative organoleptic perceptions reduced TW consumption (AOR = 0.40, p = 0.002), and hearing negative information about TWQ discouraged TW use (AOR = 0.49, p = 0.027). Reliance on BW was associated with higher SSB consumption (AOR = 2.86, p = 0.007).

Conclusions: The findings underscore the need to address TWQ perceptions and barriers to TW consumption in rural communities. Improving organoleptic qualities and building public trust in TW are essential to reducing reliance on BW and SSBs. This study provides actionable insights for healthcare providers, policymakers, and public health practitioners to implement evidence-based interventions that promote drinking-related nutritional literacy and healthy hydration behaviors, ultimately mitigating chronic disease risks.
