Appendix 



The appendix lists all NS&T sites 

 sampled in the Benthic Surveillance 

 Program from 1984-1986 and the Mus- 

 sel Watch Program from 1986-1989. 

 Benthic Surveillance sites are those with 

 only ageneral site name. Mussel Watch 

 sites are given txjth a general and spe- 

 cific site designation. If all sediment 



samples from a site contained more 

 than 80% sand-sized particles, that site 

 is indicated to be sandy and chemical 

 data from it have not been used when 

 comparing among sites. The last col- 

 umns indicate which chemical concen- 

 trations, if any, at a site exceeded the 

 "high" concentrations listed in Table 2.
