AET #01-02676 - Page 2 of 3 All boreholes were backfilled with drill cuttings. The surface at each boring location was patched with blacktop patch. A field log was maintained for each soil boring. Information on field logs include: contacts between soil layers; geologic identification (driller's opinion) of materials; notes; and other information. Soil samples were then examined in the laboratory, and soil classification information was added to the field logs. Soil identifications and descriptions are in accordance (generally) with the ASTM Visual -Manual (D2488) system as shown on the attached sheet. The samples will be discarded or returned to the Client at AET's discretion; unless within 30 days' of the report date, the client provides a written request that AET store or ship the samples, at the client's expense. Typed logs were then prepared from field logs. The typed logs may not contain all information shown on field logs. (Field logs are available for inspection by our client.) Results Typed copies of the field logs are enclosed. Refer to the attached logs for a description of the subsurface conditions encountered in the borings. The logs show: the depths to the contacts between the soil layers; the identification and geology of the soils; water level measurements; standard penetration resistance (N-column); the results of laboratory tests; and other information. We wish to point out that the split spoon samples were collected using a modified hammer weight calibrated to No values. For an explanation of this sampling method please refer to the attached Exploration/ Classification Method sheet. Please refer to the other attached sheets for descriptions of terminology used on the logs. Laboratory Tests Standard Proctor, moisture content, Atterberg Limits, sieve analysis, and R-value tests were performed on samples selected by SEH. The results of the tests are presented on the attached boring logs, gradation curves, and R-value data sheet. J
