Frequent Questions

Where should one go to access the database of the Public Water Supply shapefiles. It has been difficult to find a central location for the files, is there a way to get direction on where to go to access the shapefiles?

There aren’t any shapefiles with the PWS information, nor web services from which one would be able to extract shapefiles..  There are data portals (listed below) that will enable you to access data on PWSs. From there, you can join tables extracted from these tools to a shapefile or file geodatabase.
