Consistent and accurate measurement of public perceptions of water quality is useful for understanding water use behaviors, policy development/support, and community engagement, all essential for sustainable water management. Toward consistent and accurate measurement, we refined and examined the initial psychometric properties of a Water Quality Perception Scale (WQPS). In this study, we report an exploratory factor analysis (EFA) with 18 items on a group of respondents (N = 154), which identified one primary factor, ‘Individual Water Quality Perception,’ consisting of 13 items and two additional factors represented by the remaining 5 items. Subsequently, a confirmatory factor analysis (CFA) was performed with (n = 147 participants), including both original (n = 74 assessed at a separate time from their original assessment) and new participants (n = 73). The results of the CFA affirmed the initial loadings of the 13-item WQPS in a single factor. The scale demonstrated internal consistency, with coefficients of 0.93 and 0.90 (Cronbach’s alpha) in the two samples, and the measure showed convergent validity with the Household Water Insecurity Experiences Scale (HWISE), (r = −0.41 and −0.49 in the respective samples). This scale holds promise toward consistent and accurate measurement instrument for researching public perceptions of water quality, guiding policy and public initiatives to improve water management strategies. Avenues for further development and use are discussed. 

Integrating social equity considerations into analyses of the food-energy-water systems nexus (FEWS) could improve understanding of how to meet increasing resource demands without impacting social vulnerabilities. Effective integration requires a robust definition of equity and an enhanced understanding of reliable FEWS analysis methods. By exploring how equity has been incorporated into FEWS research in the United States and countries with similar national development, this systematic literature review builds a knowledge base to address a critical research need. Our objectives were to 1) catalog analysis methods and metrics relevant to assessing FEWS equity at varying scales; 2) characterize current studies and interpret shared themes; and 3) identify opportunities for future research and the advancement of equitable FEWS governance. FEWS equity definitions and metrics were categorized by respective system (food, energy, water, overall nexus) and common governance scales (local, regional, national, global). Two central issues were climate change, which increases FEWS risks for vulnerable populations, and sustainable development, which offers a promising framework for integrating equity and FEWS in policy-making contexts. Social equity in FEWS was integrated into studies through affordability, access, and sociocultural elements. This framework could support researchers and practitioners to include equity in FEWS analysis tools based on study scale, purpose, and resource availability. Research gaps identified during the review included a lack of studies effectively integrating all three systems, a need for publicly available datasets, omission of issues related to energy conversion facilities, and opportunities for integration of environmental justice modalities into FEWS research. This paper synthesized how social equity has previously been incorporated into FEWS and outlines pathways for further consideration of equity within nexus studies. Our findings suggested that continued exploration of connections between FEWS, equity, and policy development across scales could reduce social risks and vulnerabilities associated with these systems.
