A SURVEY OF MEASURES USED BY STATE TRANSPORTATION AGENCIES TO MITIGATE CHEMICAL WATER POLLUTANTS RELATED TO HIGHWAY FACILITIES

Caltrans conducted a letter survey in 1978-79 of the 50 state transportation agencies to determine what mitigation measures were being used to remove chemical pollutants from various sources such as hazardous spills, constituents in pavement runoff water, leachates from mineral bearing soils, sandblasting old paint from bridges, etc. Sediment derived from slope erosion and deicing salt was excluded from the survey although several states provided information on this. Responses were received from each of the states with varying amounts of information. Several states provided plans and specifications for special treatment measures that they used at a particular location. Most of the measures were site specific. Studies to identify the chemical nature of roadway-related pollutants are being conducted in a number of states. A few states indicated that no mitigation was being done primarily because no pollutant problems have been identified.
