Abstract
Drinking Water Mapping Application: Core Features and Cross-Program Approaches
Track: Water Resources
Author(s): James Rineer, Roger Anzzolin, Bill Cooter, Brandon Bergenroth
The Drinking Water Mapping Application (DWMA) provides EPA with Web-based tools to generate reports and maps vital to managing drinking water programs under the Safe Drinking Water Act. The DWMA is an application within EPA’s Watershed Assessment, Tracking & Environmental Results architecture that uses Esri ArcIMS, the Oracle database, GIS mapping layers using Esri’s SDE, and external image and feature layers from EPA, the USGS, and the Microsoft TerraServer. The current DWMA version 3 applies the enhanced National Hydrography Dataset (NHDPlus) to develop Source Protection Areas for surface water intakes based on NHDPlus catchments. The core drinking water data in the DWMA can be leveraged for other projects. Examples are given on how DWMA features can be applied in cross-program analysis tools with the EPA’s Assessment Total Maximum Daily Load Tracking and Implementation System and in a pilot project involving state-supplied information on Underground Storage Tanks.
