SAMPLING AND TEST PROCEDURES <br /> ARCADY MUD DISPOSAL SITE <br /> 10/1/87 <br /> SOIL SAMPLING: <br /> - On-Site - <br /> Soil samples will be taken from the location of the earlier <br /> borings numbered B-7, B-10, and B-11 on Figure 1 . Where-ever possible <br /> these samples will be taken from a backho x avation as follows: <br /> -1) A composite sample of the waste material from the surface to 6 <br /> inches above the base of the drill muds; <br /> -2) A composite of the lower 6 inches of the waste material <br /> immidiately overlying the basal soil. <br /> -3) Approximately 2 feet below the base of the waste pit taken by <br /> vibra-coring a small core of the underlying soil from the base <br /> of the backhoe excavation. <br /> Field logs for each excavation will be made by a geologist, and <br /> field measurements for pH will be made. Samples will be taken from <br /> the cleaned walls of the backhoe excavation using stainless steel pick <br /> or shovel, placed in a stainless steel bucket, homogenized and split <br /> into replicate samples. Wherever possible sufficent sample will be <br /> taken to allow for both check analysis and future analyses such as CAM <br /> related testing. The samples will be placed in plastic sacks (for the <br /> basal soil samples a sealed brass tube for hydrocarbon analysis will <br /> C '%tijo <br /> E <br /> CONDOR EWRONMEN AL MANAOEM <br />
