f <br /> KLEINFELDER <br /> 3 SCOPE OF woRK <br /> s <br /> , <br /> This report p presents the field and analytical results of the ground water <br /> assessment investigation conducted from March 29 to April 4, 1988. <br /> { <br /> } 3.1 DRILLING AND SAMPLING PROCEDURES <br /> - i <br /> `rf On March 29 and 30, three soil borings were drilled around the open <br /> excavation. Boring B-1 .was drilled sajacent to the southwest corner of <br /> the _store building. Boring. B-2 was drilled near the southeast corner of <br /> the property, and.boring F-3 tras drilled southwest of the excavation. The <br /> location- cf. the soil borings are shown on the.
