<br /> Borings CPT-14 and CPT-16 analytical results were non-detect for all grab samples and
<br /> at all depths.
<br /> INSTALLATION OF ADDITIONAL MONITORING WELLS
<br /> Between, 27 August and 10 October 2002, AGE prepared for and advanced seven soil
<br /> borings for the collection of soil samples and/or the installation of monitoring wells (MW-4
<br /> through MW-9). Screen intervals were installed atthe following intervals: 20 feet to 40 feet
