Census tracts with no Well Water Index (WWI) assigned
The WWI is a screening tool that uses nationally available datasets to summarize baseline characteristics about weather-related hazards and vulnerability at the census tract level for communities reliant on private wells. This dataset contains continental US census tracts for which no WWI was created due to less than 1 estimated person being on well water in the census tract. To visualize these data, please visit the Tracking Network at https://ephtracking.cdc.gov/DataExplorer/. For a lay description of these data, please visit https://ephtracking.cdc.gov/indicatorPages and for the scientific publication detailing these data please visit https://pubmed.ncbi.nlm.nih.gov/39510280/
