An Ecological Assessment of a Bridge Demolition
Report No: 75-R54
Published in 1975
About the report:
Bridge demolition has long been known to mobilize large amounts of stream sediment in the immediate area of the structure. An ecological assessment in terms of stream macroinvertebrate samples and suspended solids measurements was made shortly before, shortly after and eight months after a demolition of a bridge deck. No environmental damage was indicated by the study even though suspended solids levels exceeded 200 parts per million shortly after demolition. The U. S. Environmental Protection Agency's proposed limits for suspended solids appear to be too low for short-term stream disturbing events.
