MyEnvironment is an application built by the United States Environmental Protection Agency to help the public get a sense of environmental indicators in their neighborhood. By keying in a geography, the application comes back with information about the local land, air and water. It mines mostly EPA but also other federal Agency databases. The latest enhancement was the addition of environmental shout outs. Within the context of MyEnvironment - shout outs are a means of crowdsourcing inspirational environmental activities that are happening at the neighborhood-level. The intention is that as people are learning about air and water quality in their neighborhood, they can simultaneously learn about what their neighbors are up with regard to river cleanups, e-cycling efforts and other good-for-the-environment activities.
MyEnvironment receives over one million hits a month and over 100,000 pageviews are downloaded in that same time. The predecessor tool to MyEnvironment is Window to My Environment.
