"How is the Water?" is a simple Web app that uses location data to find Clean Water Act data about bodies of water near the user. The user's location is found using the GPS sensor from a mobile device or the IP address of a desktop browser. This functionality is only available in Firefox 3.5+, Chrome 2+, Safari 5+, Safari for iOS, Android and Blackberry. The user inputs a radius where they would like to search, and the app displays the water body's status under section 303(d) of the Clean Water Act, whether a TMDL has been developed, the date of the last data available, and a link to a full report on the EPA's website.
