Map-1 was created using three different publicly available sources: i) TRI from DOD and industries, ii) KDEP requested data for hazardous sites from the environmental protection department, and iii) ourairports.com, a publicly available website that contain all airport locations and coordinates. Indicating scores were assigned to all sites as described in method M4.1. The data and metadata for Map-2, Map-3 and Map-4 are extracted from the same publicly available source, the Kentucky Geoportal. The methods (M1-5) below include the procedure to make hot-spot maps for PFAS and other linked water systems maps in ArcGIS. The method, M6 describes the standard operating procedures for depositing the resulting GIS files in Figshare.
