Water quality characterization of bridge deck runoff in NC

This project was completed in 2012. These pages are for historical purposes only.


Results of the bridge deck stormwater quality monitoring, stream water quality sampling, streambed sediment sampling, and empirical mixing calculations of bridge stormwater constituents with receiving waters will be used to characterize and document the bridge deck runoff and effects of bridge deck runoff on receiving water.

An online USGS Scientific Investigations Report, documenting the data collection and approach used to characterize the bridge deck runoff and determine the impact of bridge deck runoff on receiving waters of the state, has been published and is available online at
