Climate Change Risk Index Values for Medium- and Large- Municipal Drinking Water Utilities in the Contiguous United States

Climate change poses risks to the operational and financial reliability of drinking water utilities across the United States (US). This dataset includes climate hazard projections, indicators of exposure and vulnerability, and comparative risk index for 1,455 medium and large municipal drinking water systems in the contiguous US. The methods and data used to create this dataset are detailed in the future publication:Lyle, Z., VanBriesen, J.M., Samaras, C. (2025). “Drinking water utility system exposure and vulnerability to climate change.”
