In 1999, ODW developed a Source Water Assessment Program, as a result of the <a href=\"http:\/\/www.gpo.gov\/fdsys\/pkg\/PLAW-104publ182\/html\/PLAW-104publ182.htm\" target=\"_blank\">1996 Amendments to the Safe Drinking Water Act (SDWA), Section 1453<\/a>. By 2003, all existing drinking water sources were assessed.<\/p>\n<p>The objective of the Source Water Assessment Program is to facilitate and promote the implementation of <a href=\"https:\/\/www.vdh.virginia.gov\/drinking-water\/office-of-drinking-water\/source-water-programs\/source-water-protection-program\/\">source water protection<\/a> measures among the waterworks community. To achieve this, ODW delineates an assessment area for each drinking water source and creates an inventory of potential sources of contamination using <a href=\"https:\/\/www.vdh.virginia.gov\/drinking-water\/drinking-water-data\/\">Geographic Information Systems (GIS)<\/a>. This information is used to make a susceptibility determination of the drinking water source in relation to the potential source of contaminants found in the assessment area.<\/p>\n<p>In 2013, ODW began working with WorldView Solutions to organize and manage source water data previously collected by ODW and to create a customized reporting tool into ArcGIS. This custom-created tool used within the GIS platform allows ODW to collaborate more effectively with waterworks and their consultants, particularly when pursuing\u00a0<a href=\"https:\/\/www.vdh.virginia.gov\/drinking-water\/office-of-drinking-water\/source-water-programs\/source-water-protection-program\/\"><strong>source water protection<\/strong><\/a>.
