WATER QUALITY AND HYDROGRAPHY 



General water quality information, including dissolved oxyqen, 

 salinity, pH, temperature and public-health related data (primarily 

 total fecal coliform bacteria counts) is available from a number of 

 studies. Data on nutrients and trace contaminants are more limited. 

 Information on hydrographic characteristics is available from studies 

 conducted both in New Haven Harbor and Long Island Sound. 



Data for New Haven Harbor are available from Duxbury (1964) , 

 who provided seasonal information on nutrient concentrations and distri- 

 butions and current regimes in the harbor. Beginning in 1968 the United 

 States Geologic Survey Water Resources Division (U.S.G.S., 1968-1977) 

 conducted a general water resources survey, providing data on a wide 

 spectrum of water quality and chemical parameters involving several 

 samplings per year from stations in the Quinnipiac and Mill Rivers and 

 New Haven Harbor. A later study (1970, unpiiblished) conducted by the 

 Federal Water Quality Administration provided measurements of dissolved 

 oxygen and pH from inner and outer harbor locations. NAI (1971a, 1972, 

 1973, 1974a, 1974b, 1975a, 1976a, 1977a, 1978) has provided a substan- 

 tial water quality data base (temperature, dissolved oxygen, pH, salin- 

 ity and turbidity) for the inner and outer harbor regions. Additional 

 water temperature data are available from aerial infrared surveys (Good- 

 kind & O'Day and Fay, Spofford, and Thorndike, 1970; NAI, 1971, 1977b) for 

 determining effluent plume configurations and from thermal plxime base- 

 line studies for the English Station (NAI, 1971) and New Haven Harbor 

 Station (EBASCO, 1971b; NAI, 1976b) . The Goodkind harbor model was 

 directed primarily toward modeling of dissolved oxygen and biological 

 oxygen demands of various sewage treatment/outfall location schemes. 



Duxbury 's study on water circulation in New Haven Harbor has 

 been the only major effort to utilize a full field measurement program. 

 Duxbury 's general circulation patterns and current velocities have 

 served as basic elements of nearly all subsequent hydrodynamic work in 

 New Haven Harbor. These data were used in the circulation model of
