Environmental Geographic Information System

The Environmental Planning Office (EPO) closed effective May 2, 2018.  Due to federal EPA funding reductions, the office is no longer providing services.  The information posted here will temporarily remain in place for public reference.  For Standard Comments, please see the EPO Land Use Planning Review webpage or contact the appropriate Environmental Health Administration branches and offices directly using DOHEHALandUseContactList_20221024.pdf.


The Environmental Geographic Information System (EGIS) provides GIS services and support to a wide range of DOH programs and the public.  By linking spatial and database information, EGIS enables the visualization and analysis of environmental patterns, relationships, and trends.  This dynamic system provides vital information and fresh perspectives on environmental issues.

Currently, EGIS is working on gathering new datasets to provide additional, high-quality informational maps for the people of Hawaii.

Safe Drinking Water Branch (SDWB)


The Groundwater Contamination Viewer uses monitoring data for public drinking water wells, select non-potable wells, fresh water springs, and other testing data available to the DOH. The system identifies organic and other chemical contaminants that have been detected and confirmed in drinking water wells, select non-potable wells, and fresh water springs throughout Hawaii.


Underground Injection Control (UIC)

Underground Injection Wells are wells used for injecting water or other fluids into a groundwater aquifer. Department of Health Administrative Rules, Title 11, Chapter 23 provides conditions governing the location, construction, and operation of injection wells so that injected fluids do not migrate and pollute underground sources of drinking water. Section 4 of the Rules gives the criteria for classifying aquifers into those that are designated as underground sources of drinking water and those that are not.

The boundary between non-drinking water aquifers and underground sources of drinking water is generally referred to as the “UIC Line”. Restrictions on injection wells differ, depending on whether the area is inland (mauka) or seaward (makai) of the UIC line.

The UIC Maps show the areas inland and seaward of the UIC line on all major islands. These maps are meant for general informational purposes only. The Department holds the official UIC maps containing detailed information about the UIC Line. For more information, contact the Safe Drinking Water Branch’s UIC Program.

Recycled Water

Recycled water use maps designate areas where the use of recycled water is restricted, conditional, or unrestricted. Although most areas allow for unrestricted recycled water use, certain sensitive areas that may be potentially impacted by recycled water use are subject to notification and monitoring requirements.

The Recycled Water Use GIS Web App allows users to search by TMK or address to determine their recycled water use classification. Click here: Recycled Water Reuse Web App

Reuse Guidelines (revised in January 2016) on recycled water are now posted at the following site, along with application forms, report forms, and a summary presentation of the revisions:

Environmental Justice: EJSCREEN

EJScreenThe US Environmental Protection Agency (EPA) has developed its own environmental justice GIS:

In order to better meet the Agency’s responsibilities related to the protection of public health and the environment, EPA has developed a new environmental justice (EJ) mapping and screening tool called EJSCREEN. It is based on nationally consistent data and an approach that combines environmental and demographic indicators in maps and reports.

Water Viewer

This robust, online mapping tool provides the public, water system operators, state programs, and federal agencies with critical information to help them safeguard the source of America’s drinking water:

EPA CAMEO (Computer-Aided Management of Emergency Operations) is a system of software applications used to plan for and respond to chemical emergencies. Developed by EPA and the National Oceanic and Atmospheric Administration to assist front-line chemical emergency planners and responders, CAMEO can access, store, and evaluate information critical for developing emergency plans.

Honolulu Land Information System (HoLIS): Interactive Map Selector

The City and County of Honolulu has developed one of the most comprehensive GIS data base for any municipality of its size. The Honolulu Land Information System (HoLIS) is an enterprise-wide system serving over 15 City Departments with land use, permit, tax, infrastructure, and environmental data. Geographically referenced information links existing City records to precise locations on the island of Oahu for spatial query and analysis.
