Remediation And Stabilization Of Soils Contaminated By Lead Resulting From The Removal Of Paint From Bridges, M. K. Banks, A. Paul Schwab

JTRP Technical Reports

Lead-based paints are commonly used for painting steel bridge structures. Soils in the immediate vicinity of older bridges have been contaminated with Pb as a result of normal weathering and peeling of the paint coupled with removal prior to repainting. The objectives of this project were to assess the extent of lead contamination near highway bridges and to evaluate phytoremediation and immobilization as means of remediation. We examined soils in the vicinity of approximately 20 bridges in Indiana that had been repainted recently and were know to have been painted originally with Pb-based paint. We found only three bridges in …
