Motivators and Hindrances of Consuming Reusable Water Bottles: An Exploratory Case Study at Columbia University

Abstract

This pilot study explores the factors that motivate and hinder tap water consumption and reusable water bottle usage among students at Columbia University. Despite Manhattan's tap water being among the highest quality globally, the prevalence of single-use plastic water bottles on campus remains significant. Choosing reusable water bottles over single-use plastics is a pro-environmental behavior that can reduce plastic production and waste. This research investigates the underlying reasons behind students' choices regarding tap water consumption and reusable bottle usage. The data were collected from 58 students selected through convenience sampling utilizing questionnaires and participant observation. The questionnaire responses were thematically coded, and descriptive statistics, including percentages and frequencies, were used to analyze the data. Findings indicate that, while a relatively high percentage of students consume tap water compared to other universities, hygiene concerns related to water quality are the main hindrances. In terms of bottle usage, the primary motivation for carrying a reusable water bottle was to increase water intake. The major barrier was the inconvenience and lack of portability of reusable bottles. Notably, students overestimated the positive environmental impact of using reusable water bottles, which could potentially lead to greater environmental harm due to misconceptions. This pilot study underscores the need for further in-depth research to identify and address the misconceptions and barriers affecting students' pro-environmental behaviors.
