The maps on this site depict demographic and infrastructural data as well as potential sources of environmental contamination and storm damage data in Alabama, Mississippi, Louisiana, and Texas.

Dynamic GIS information can be found under the ArcIMS Browser tab.

These pre-formatted maps are intended to support the environmental health community's efforts to address the uncertainty of risk of exposure to the contaminants entering the environment as a result of Hurricanes Katrina and Rita.

If you feel there are maps or information that should be displayed on this page, please contact: hurricanegis@niehs.nih.gov

We will continually update this site as we obtain and process additional GIS information. In the near future, this site will include enhanced functionalities and additional data such as gridded population data, hydrography, drinking water, and ocean floor mapping data.
