2 Welcome to DWMAPS
The Drinking Water Mapping Application to Protect Source Waters (DWMAPS) is an online
mapping tool that provides state and utility drinking water professionals, watershed protection
groups, source water protection partnerships, and others with information to update source
water assessments and prioritize source water protection measures in any location or
watershed in the country. DWMAPS includes several search tools that, when used together
with state and locally available mapping tools and data, can help users:
S Identify potential sources of contamination;
S find data to support source water assessments and plans to manage potential sources of
contamination;
S evaluate accidental spills and releases, identifying where emergency response resources
for accidental releases must be readily available;
S promote integration of drinking water protection activities with other environmental
programs at the EPA, state, and local levels; and
S identify source water protection partnerships and watershed projects.
DWMAPS provides geographic data regarding the nation's sources of drinking water and public
water systems but obscures the precise locations of Public Water System intakes. DWMAPS has
been designed to work in tandem with local data and information to assist with source water
protection and emergency preparedness.
The DWMAPS application contains map controls, search tools, and interactive data displays to
help users navigate, visualize and sort through map data. Search tools can be accessed through
the Welcome Screen or toolbar located in the primary map display.
DWMAPS is hosted on EPA's GeoPlatform and integrated with Esri ArcGIS Online, a dynamic,
expansive, and collaborative web platform that allows users to create and share data, maps,
analytics, and mapping applications. Users do not need access to additional software, such as
ArcGIS, to use DWMAPS. This user guide provides step-by-step instructions for each search tool
and navigational feature-including those provided through ArcGIS Online located within
DWMAPS. Use the following link to access DWMAPS: https://geopub.epa.gov/DWWidgetApp/.

5.5 Attribute Table
The Attribute Table tool (Figure 2, Map Element S) lists information for features in
the map layer in tabular format. Users may use this tool to filter and select
(highlight) attributes to view in the map and in the attribute display. Attributes
tables are available for Layer List layers and user-added external layer services that
are query capable. A query capable layer will have the Open Attribute Table option
available in the layer's description tab.
5.5.1 Open Layer Attribute Table
1. Click the Attribute Table tool icon in the bottom right corner of the DWMAPS map
display (Figure 29).
S The attribute table will display below the map panel. Attribute table field names
appear above the feature values (Figure 29).

6 Search Tools
The DWMAPS application contains several search tools that enable users to filter, select, and
view information to help them locate drinking water providers, locate potential sources of
contamination, located polluted waterways, and locate projects and source water
collaboratives. Users can access search tools either on the Welcome Screen or on the Search
Toolbar at the bottom of the Map Display.

The Locate Drinking Water Providers tool (Figure 2, Map Element K)
provides information on Public Water System (PWS) service areas and
sources of drinking water. Service area information is displayed at the
county level, while drinking water source information is displayed by
Hydrologic Unit Code (HUC 12) watershed. The tool provides links to
information, including service population, source type, and violations,
reported by the state, tribe or territory, within EPA's Safe Drinking Water
Information System (SDWIS). DWMAPS does not display the actual
locations of Public Water System intakes facilities.
1. Select the Drinking Water Providers tool from the Welcome Screen;

contaminant sources are indicated by a yellow icon in map. Further
details on each potential contaminant source identified, including
enforcement and compliance history, are made available in a results
window. This search tool intends to help users identify where they may
be able to engage in the CWA to protect sources of drinking water. Refer

6.3 Nearby Discharges
Use this search tool to find potential sources of contamination, source water protection projects,
and waters identified as impaired under Clean Water Act 303(d) provision and Total Maximum
Daily Load (TMDL) waters within a search radius.
The Nearby Discharges tool (Figure 2, Map Element J) locates NPDES-permitted discharge
points, Clean Water Act Section 319 nonpoint source pollution projects, impaired waters (under
CWA Section 303(d)), and assessed waters (under Section305(b)). Unlike the Potential Sources
of Contamination tool, which provides results upstream from a given point, the Nearby
Discharges provides results that fall within a specified radius (1 to 30 miles) of an address,
place, or specified location by clicking on the map. The tool is not located on the Welcome
Screen but can be found at the bottom of the DWMAPS map display.
1. Select the Nearby Discharges tool from the tool bar at the bottom of the map display
(Figure 58).

6.4 Polluted Waterways
Use this search tool to locate polluted waterways.

Locate
Polluted
Waterways
The Clean Water Act (CWA) requires states to identify waterbodies
rivers, streams, and lakes that are "impaired," or not meeting the water
quality standards to support activities such as recreation, fishing, and
public water supply. The Locate Polluted Waterways search tool (Figure
2, Map Element M) allows users to search for CWA waterways that are on
impaired waters list and/or have an active Total Maximum Daily Load
(TMDL). This search tool intends to help users identify where they may be
able to engage in the CWA to protect sources of drinking water. Refer to
the Clean Water Act-Safe Drinking Water Act Coordination Toolkit for
more information.
1. Click the Locate Polluted Waterways box on the Welcome Screen
Or;
Select the icon from the search bar at the bottom of the DWMAPS map display (Figure
67).

6.5 Projects and Source Water Collaboratives
Use this search tool to locate watershed projects and source water collaboratives working in a
specified area.
The Locate Projects and Source Water Collaboratives tool (Figure 2,
Map Element N) locates and displays the location of ongoing and
completed Nonpoint Source Management Program grants funded by
Section 319 of the Clean Water Act and the location of source water
collaboratives. The tool identifies projects upstream of a user-defined
location. This tool is intended to inform users about source water
protection activities and programs in their area so that they may get
involved. For more information on source water collaboratives and tools
for source water protection visit the national Source Water Collaborative
website.
