WaterGoodness is a new site allowing users to share and find water quality reports across the United States. The site combines water quality and pollution data from a variety of government sources with visitor reports of their local water quality.
By searching the US Environmental Protection Agency's database, GreenSpaceMap offers visitors the ability to locate environmental threats in their neighborhood or region. Locations like Superfund sites and brownfields are visible once you type in a starting address. This is also an entry in the Sunlight Labs Apps for America contest.
