6.3 Volxime. Sediment Analysis 



On June 3, 1988 two samples from the area 

 to be dredged were taken. The sites 

 chosen are shown on the accompanying 

 exhibit. These samples were extracted by 

 drilling down fifteen feet and removing a 

 core sample. The samples were tested for 

 heavy metals, polychlorinated biphenyls, 

 and other contaminants. The results of 

 the testing reveal that the area to be 

 dredged is for the most part either 

 category one or two type material, as 

 defined in DEQE regulations 314 CMR 9.00. 

 Of the two testing sites, only the lead 

 level of the inshore sample is at 

 category three levels. The other sample 

 revealed a lead level of category two. 

 The mercury levels were both low or below 

 category two and the arsenic, cadmium, 

 and chromium levels at both sample sites 

 were category one. (See Appendix E for 

 the complete dredge spoils analysis) .
