National Status and Trends (NS&T) values are averaged for each site over the period of time sampled. 

 All data are normalized to the percent fine grain size (silt+clay) in that sample. 

 NS&T Location LIHH LIS-Hempstead Harbor 



LIHU LIS-Huntington Harbor 



LIMR LIS-Mamaroneck 



LISI LIS-Sheffield Isand 



LITN LIS-Throgs Neck 



WLI Western Long Island Sound 

 For specific locations of NS&T sites, see NOAA 1991. 

 NERBC = New England River Basins Commission (NERBC 1980) moderately contaminated 



category for sediments (CT, NY). 

 All values are nomalized to a maximum estimate of 90% fine-grained percentage; see text for explanation.
