Include (1) expanded data collection activities particularly in areas of poten- 

 tial development and existing centers of ground-water pumpage, (2) monitoring 

 of ground-water quality to evaluate long-term changes due to man's activities, 

 (3) determination of the hydraulic properties of stratified drift and sedi- 

 mentary bedrock aquifers, (4) definition of the geometry and pattern of ground- 

 water circulation In the sedimentary bedrock of Subregion 3. 



6.0 BRACKISH AND SALT WATER BODIES 



Salty and brackish waters occupy Long Island Sound, the lower 

 reaches of the streams that drain into the Sound and the coastal and offshore 

 parts of the ground-water reservoirs. This section is concerned with the 

 Sound and saline parts of the estuaries because little is known about the 

 movement of salty ground water in the region. Some geographic features of 

 the Sound such as area and volume have already been noted on pages 5 and 6, 

 and detailed information on the configuration and depth is shown on hydro- 

 graphic charts and bathymetric maps (2J_, kO) published by the National Ocean 

 Survey. Figure 15 shows several geographic features of the Sound and the 

 principal estuaries referred to in this report.
