GENERAL BORING NOTES:

THESE LOGS ARE AVAILABLE FOR INSPECTION BY REQUEST TO THE CONTRACTING OFFICER.

8. THE BORINGS SHOW SUMMARIES OF INFORMATION RECORDED ON THE ORIGINAL FIELD LOGS.

UNLESS SPECIFIED OTHERWISE, ALL CORE IS 4-INCH DIAMETER.

PERCENT RECOVERY IS LENGTH OF CORE RECOVERED/LENGTH OF CORE CUT X 100.

7. % RECOVERY: PERCENT CORE RECOVERY IS SHOWN TO THE LEFT OF THE BORING STAFF.
