Department of Transportation.— The Federal 

 Highway Administration is developing a prediction 

 method for forecasting water quality changes in 

 streams due to highway construction in drainage 

 basins. Studies are being conducted on the evaluation 

 and control of water quality and the adverse effects of 

 highway construction on aquatic life. Erosion control 

 during highway construction is being studied and 

 analyzed in order to decrease stream sedimentation 

 and damage to areas affected by drainage from 

 construction sites.

Department of the Interior.— Most of the 



ecologically related research being performed in this 

 area is being supported by the Bureau of Reclamation 

 in connection with proposed dams, irrigation systems, 

 and similar public works in the west. The Geological 

 Survey conducts research on the geologic and 

 hydrologic components of planning of structures (e.g., 

 warm oil pipelines in Alaska).

National Science Foundation.— Research activity 

 considers impact of construction on ecological systems 

 and the resulting changes in the environment. These 

 studies include coastal construction as well as urban 

 industrial development.
