   Houck, Kelly M. ; Terán, Enrique ; Ochoa, Juan ; Zapata, Gyssell N. ; Gomez, Ana M. ; Parra, Rafael ; Dvorquez, Denise ; Stewart, Jill R. ; Bentley, Margaret E. ; Thompson, Amanda L. ( November 2019 , American Journal of Human Biology)

   The Galápagos provides an important setting to investigate the health impacts of a new drinking water treatment plant (DWTP) in a limited resource environment. We examine how household perceptions and practices affect the relationship between water quality and infections before and after DWTP.

   Ethnographic data and self‐reported infections were collected from 121 mothers and 168 children ages 2 to 10 from Isla San Cristóbal. Household tap water samples were tested for levels of fecal contamination. Community level infection rates were estimated using discharge records from the Ministry of Public Health. The effects of the new DWTP and fecal contamination levels on infections were tested using logistic and Poisson models.

   Perceptions of water quality and household practices influenced exposures to contaminated tap water. We found minimal change in drinking water sources with 85% of mothers sampled before the DWTP and 83% sampled after using bottled water, while >85% from the pooled sample used tap water for cooking and hygiene practices. The DWTP opening was associated with lower odds of fecal contamination in tap water, reported urinary infections, and community level rates of urinary and gastrointestinal infections. The household practice of recently washing the cistern contributed to higher contamination levels after the DWTP opened.

   To ensure access to clean water, public health works need to consider how household perceptions and practices influence tap water use and quality, in addition to infrastructure improvements. Exposures to contaminated tap water contribute to the burden of infectious disease in environments with inadequate water infrastructure.

2. Structural equation modeling to identify social drivers for water use in low-income communities in Southern Texas

   Saleh, N. B. ; Rowles III, L. S. ; Lawler, D. ( March 2019 , 257th American Chemical Society National Meeting)

   The colonias in Texas along the Mexican border are self-built neighborhoods of low-income families that lack basic infrastructure. While some funding from the State of Texas has built roads and provided electricity, water and sewage systems are still lacking for many of the estimated 400,000 colonias’ residents. Of those that do have tap water, the supply is either inadequate or of questionable quality. These communities have suffered from waterborne disease, such as cholera epidemics, over the past few decades. This research is the first to collect a comprehensive dataset on water use, socio-economic parameters, and actual water quality in selected colonias in several counties in Texas. A quantitative statistical model has been developed using structural equation modeling, that relates social drivers for water use and management with actual water quality. Water quality parameters measured in these communities include traditional microbial indicators (total coliforms, E. coli, and heterotrophs), pH, hardness, free and total chlorine, and metals (arsenic and lead). The model explores relationships among latent variables relating water, health, and living situation to assess potential impacts of a water treatment technology in these low-income households. The study provides quantitatively reports for the need and desire of adopting a point-of-use treatment system, evaluates the relationship between perceived versus actual water quality, and determines the factors that influence the choice of drinking water. This model can be adopted for identifying social drivers for water use and management in other low-income communities in the United States.

3. Bottled vs tap water perceptions, choices and recommendations in a US Midwest university community

   https://doi.org/10.1108/IJSHE-01-2022-0007

   Purpose This study aims to determine preference and concerns regarding tap vs bottled water and recommendations to increase tap water use in a US Midwest university. The authors propose interventions to increase tap water use based on survey results. Design/methodology/approach The authors conducted an online survey of the community of a regional comprehensive university in the St. Louis metro-east region (Illinois, USA). They analyzed 781 responses using mixed methods, and developed recommendations based on community-based social marketing principles. Findings Black respondents reported higher bottled water use than White respondents. Undergraduate students reported higher bottled water use than faculty or staff. Most respondents were concerned about cost and environmental impact for bottled water and taste and water quality for tap water. Chemical and safety concerns were specific and location-focused for tap water only. Concerns were similar to Safe Drinking Water Act mandated public information, such as prior reports of lead (Pb) in campus drinking water. Tap water taste concerns may relate to proximity to the water treatment plant, resulting in high residual chlorine levels. To increase tap water use in this community, the authors recommend persuasive information campaigns, improvements to infrastructure and distribution that increase tap water convenience, more transparent public reporting on tap water lead levels, management of residual chlorine levels, and establishment of institutional norms favoring tap water over bottled water. Originality/value The authors evaluate barriers to drinking tap water across multiple environmental and social systems. The methods used in this study combine mixed methods analysis and community-based social marketing. The findings integrate respondent demographics and concerns, local water quality, local and national contamination events, campus-specific sustainability initiatives and barriers, and national drinking water regulations.

4. Awareness Is Not Enough: Frequent Use of Water Pollution Information and Changes to Risky Behavior

   https://doi.org/10.3390/su12208695  

   Ross, Ashley D. ; Hotard, Abbey ; Kamalanathan, Manoj ; Nolen, Rayna ; Hala, David ; Clay, Lauren A. ; Kaiser, Karl ; Quigg, Antonietta ( October 2020 , Sustainability)

   Hazard information plays an important role in how risk perceptions are formed and what actions are taken in response to risk. While past studies have shown that information on water and air pollution is associated with changes to individual behavior, there is a need for examination of water quality information in the context of environmental disturbances. This study fills that gap by examining water pollution in an active industrial region of the United States—the Galveston Bay of Texas. Using original survey data collected in 2019 of 525 adults living in the Galveston Bay region, logistic regression was used to analyze the association of awareness and use of water pollution information on changes to outdoor activities and consumption of drinking water and/or seafood. Controls for chronic and acute exposure to environmental hazards, environmental knowledge and experience, and demographics were included in the model. The findings indicate frequent use of water quality information is significantly associated with action to reduce risk. On average, an individual who checks water pollution monitoring every day is 26% and 33% more likely to change their outdoor activities and consumption behavior, respectively, than someone who is not aware of this information. There is a need for improvement in pollution data collection and the development of a risk communication framework that facilitates the dissemination of this information in relevant, accessible, and credible ways.

5. How Do Perceptions of Risk Communicator Attributes Affect Emergency Response? An Examination of a Water Contamination Emergency in Boston, USA

   https://doi.org/10.1029/2021WR030669  

   Hyman, Amy ; Arlikatti, Sudha ; Huang, Shih‐Kai ; Lindell, Michael K. ; Mumpower, Jeryl ; Prater, Carla S. ; Wu, Hao‐Che ( January 2022 , Water Resources Research)

   A water main break that contaminated the Boston area's water distribution system prompted a four‐day “boil water” order. To understand risk communication during this incident, 600 randomly sampled residents were mailed questionnaires, yielding 110 valid responses. This article describes how perceptions of different social stakeholders influenced whether respondents complied with the Protective Action Recommendation—PAR (i.e., drank boiled water), took alternative protective actions (i.e., drank bottled water or/and self‐chlorinated water), or ignored the threat (i.e., continued to drink untreated tap water). Respondents perceived technical authorities (i.e., water utility, public health, and emergency management) to be higher on three social influence attributes (hazard expertize, trustworthiness, and protection responsibility) than public (i.e., news media, elected officials) and private (i.e., self/family, peers, and personal physicians) intermediate sources. Furthermore, respondents were most likely to comply with the PAR if they perceived authorities and public intermediates to be high on all three attributes and if they had larger households and lower income. Contrarily, they were more likely to take alternative actions if they were younger and had higher levels of income, risk perception, and emergency preparedness. These results underscore the need for technical authorities to develop credibility with their potential audiences before a crisis occurs.
