    Human Right to Water Data Tool (CalHRTW 1.0)

    Metadata Updated: August 23, 2025

    OEHHA’s Human Right to Water Framework and Data Tool (CalHRTW 1.0) is comprised of this web-based data tool and an assessment report, Achieving the Human Right to Water in California: An Assessment of the State’s Community Water Systems. The purpose of CalHRTW 1.0 is to provide a comprehensive, stand-alone, quantitative assessment of the human right to water for three core components: water quality, water accessibility and water affordability. This data tool allows users to access and explore information in these three core areas interactively.

    CalHRTW 1.0 measures and scores nine indicators across the three core components for each of the state’s 2,839 active community water systems (as of January 2019). Indicator scores within each of the three components are combined to create three individual composite component scores to illustrate a system’s overall status in providing clean, accessible and affordable water to its customers. Scores range from 0 to 4, with higher scores indicating worse outcomes. The data used is for 2011 to 2019.
