(4) Studies should be conducted to evaluate the movement 

 and dispersion of releases of sludge at sites currently in 

 use, such as in the New York Bight and off southern 

 California. These studies should include, but not 

 necessarily be limited to, investigation of the methods 

 of introducing the sludge, i.e., by barge or outfall, and 

 the transport mechanisms, including settling and resuspen- 

 sion, which influence the distribution and spread of the 

 materials.
