o No acid/base or neutral extractable compounds were 

 detected above the method detection limits in the 

 groundwater sample taken from B103-OW. 



Four of the thirteen dissolved priority pollutants 

 were detected in the groundwater sample taken from 

 B103-OW at the following concentrations: 



Copper 0.02 mg/1 (parts per million [ppm]) 



Lead 0.07 



Selenium 0.024 



Zinc 0.06 



U.S. EPA Drinking Water Standards and Massachusetts Class 



1 and II Groundwater Standards for copper (1.0 ppm) and 

 zinc (5.0 ppm) were not exceeded by the sample from 

 B103-OW. However, the U.S. EPA Drinking Water Standards 

 and Massachusetts Class I and Class II Groundwater 

 Standards for selenium (0.01 ppm) and lead (0.05 ppm) were 

 not met by the sample from B103-OW. 



B. Soil Sample Analyses 



Twelve soil samples obtained during the test boring 

 program were submitted for chemical analysis to assess the 

 quality of the fill and soil materials which underlie the 

 site. Details pertaining to the analysis of these fill 

 and soil samples follow. 



Two substrata have been tentatively identified within the 

 fill materials. Soils which are believed to be the most 

 recent fill material is generally described as loose, 

 brown to black coarse to fine sand, with cinders, brick 

 and fine gravel, and was encountered at depths ranging 

 from one to six feet below the ground surface at all three 

 land borings. Underlying this top fill layer, a second 

 fill deposit was encountered. This material is generally 

 described as medium dense, brown medium to fine sand with 

 silt, brick, cinders and fine gravel, and was found to 

 range in thickness from approximately four to eight feet. 



Six soil samples were selected from the top most layer of 

 fill for chemical analysis. Sample B102(S1), which had
