6 . CONCLUSIONS <br /> This investigation included six soil borings, with depths from 5 <br /> to 30 feet, from which five soil samples and four groundwater <br /> ' samples were collected for analysis . All samples were analyzed <br /> for priority metals and for cyanide, and three were analyzed for <br /> numerous toxic organic compounds (volatile, semi-volatile, chlo- <br /> rinated pesticides) . <br /> ' Priority metals were either not detected or were detected at very <br /> low (background) levels in all samples; silver, a metal used <br /> ' abundantly in past electroplating operations, was not detected. <br /> Cyanide, also used abundantly, was not detected in any samples . <br /> Of the numerous organic compounds tested, only one, bis- (2 ethyl- <br /> hexyl)phthalate, was detected; this had very low concentration <br /> ' (around 22 ug/1) in groundwater samples B-2-W and B-4-W, located <br /> respectively up- and down-gradient from the area of Shinko' s <br /> chemical operations . This indicates that the compound originates <br /> ' off-site, probably up-gradient (to the north) . <br /> The information developed by this investigation and presented <br /> ' herein provides good evidence that past activities on the Shinko <br /> site have not measurably impacted soil or groundwater beneath the <br /> property. <br /> 1 <br /> ' 6 <br />
