The map links below provide the user with surface water quality assessment information found in the Integrated Report of Surface Water Quality. These pages each have an embedded map (similar to Google Maps) capable of showing stream-segment level assessment information. No special software is needed although the map will perform better with the latest version browsers (e.g. Internet Explorer 9 or later, Mozilla Firefox version 40.0.1, Google Chrome). Maps were split into major pollution-type groupings to avoid having an abundance of overlapping assessment information. The data shown via the links below is the most current information, displaying IR assessment information from Maryland's EPA-Approved 2014 Integrated Report of Surface Water Quality.
Please note: All of the maps below are symbolized according to the Integrated Reporting category. Click here to view descriptions of the Integrated Reporting categories. Click here to view an on-line video tutorial on how to use the maps.
Also included, at the bottom of the page, is a link allowing users can download the latest Integrated Report geodatabase (ESRI ArcGIS format).

Download MD's 2014 Integrated Report Individual Water body-Pollutant Layers
This geodatabase has all of the same water quality assessment information that the geodatabase above contains, however; instead of being a relational geodatabase, it contains pre-made layers each depicting a single water body-pollutant combination (e.g. impoundments assessed for sediments). Click the "Download..." link above for a zip file which includes this information.
