If you're a journalist who wants water quality data that's for "non-geeks. . . The Environmental Protection Agency is offering a 'How's My Waterway?' web app that makes the sophisticated stuff simple," reports Joseph A. Davis of the Society of Environmental Journalists. "If you are, indeed, a geek and want to jump ahead, you can start exploring it here. . . . This app is a portal for people who just want to know whether they can drink from or swim in their local river. It's hyperlocal and practical. It's presented graphically and intuitively."

Where did the data come from? "The good news is that the EPA answers the question. The other good news is that it comes from multiple authoritative datasets," Davis explains. "Much of that data is required by law to be collected by government agencies and is therefore fairly good. Those datasets include ATTAINS, a collection of water quality data posted by the states, and BEACON 2.0, a collection of state data about beach closings. . . . It also includes discharge permit information, as well as permit violations. And drinking water information. And, yes, more. Here's the full list."

Using the app is as easy as downloading it on your smartphone and entering your ZIP code. The app then shows a map. "Like a good pair of binoculars, it allows you to zoom in or out or to ask about water quality at the local, state, or national level. In the process of describing state and national-level water quality, it actually provides some meaningful overview analysis," Davis reports. "The data is not up-to-the-second, but it is pretty current. The time frame differs for each kind of data, which is only the beginning of the story — a launch pad for shoe-leather and phone reporting."
