Development can have negative effects on streams in urban and suburban areas.

Urban development is associated with an increase in impervious surfaces, that is, surfaces such as rooftops, sidewalks, and streets that prevent precipitation from infiltrating into the groundwater.  Impervious surfaces increase the volume and energy of stormwater that reaches streams and can lead to adverse physical and water quality impacts, including erosion

This video discusses how scientists have tracked what, when, and how contaminants may reach public-supply wells in four aquifers in California, Connecticut, Nebraska, and Florida.
