Methodology & Interpretation

  • State values are weighted averages of scored drinking-water service markets within each state. They are not full-population state stress estimates.
  • Coverage and confidence vary by state. States with fewer scored markets may have wider confidence bands.
  • Methodology upgrades can change comparative rank because saturated factors may be weighted differently. A lower rank after a methodology update is not, by itself, evidence of system improvement.
  • The headline composite is a blended structural stress measure. Use the component bars to separate infrastructure-heavy readings from socioeconomic or observability-heavy ones.
  • Scores are generated using the current MISI methodology. Version and vintage dates are noted in each score record.

Drinking Water Infrastructure Conditions Across U.S. States

This dataset tracks infrastructure stress across community drinking water systems in all U.S. states, enabling comparison of system conditions, trend behavior, and structural risk indicators over time.
