CROSS SECTION NOTES:
1. GROUND WATER LEVEL MEASUREMENTS WERE TAKEN ON JUNE
12, 2016. DEPTH TO WATER WAS MEASURED WITH AN
ELECTRIC PROBE FROM BELOW TOP OF CASING AND WAS
RECORDED WITHIN 0.01 FEET. WATER LEVELS PRESENTED ON
CROSS SECTIONS ARE FROM SHALLOW WELLS ONLY AND
REPRESENT THE WATER TABLE. SHALLOW WATER LEVELS WERE
NOT MEASURED FOR BG -105, MW -215, MW -225, GWA-205,
OR GWA-175. WATER TABLE SYMBOLOGY IS PRESENTED
BELOW. 4
2. RECOVERY (REC) AND ROCK QUALITY DESIGNATION (RQD) ARE
MEASUREMENTS OF THE QUALITY OF ROCK CORE RECOVERED
FROM A BOREHOLE.
3. STANDARD PENETRATION TESTING (SPT), REC AND ROD WERE
THE PRIMARY SOURCES OF DATA USED IN THE
DETERMINATION/ASSIGNMENT OF HYDROSTRATIGRAPHIC LAYERS
TO NATURAL MATERIALS (ALLUVIUM, SOIL, SAPROLITE, AND
ROCK) IN A BOREHOLE; REVIEWS OF THE BOREHOLE LOGS,

CROSS SECTION NOTES:
1. GROUND WATER LEVEL MEASUREMENTS WERE TAKEN ON JUNE
12, 2016. DEPTH TO WATER WAS MEASURED WITH AN
ELECTRIC PROBE FROM BELOW TOP OF CASING AND WAS
RECORDED WITHIN 0.01 FEET. WATER LEVELS PRESENTED ON
CROSS SECTIONS ARE FROM SHALLOW WELLS ONLY AND
REPRESENT THE WATER TABLE. SHALLOW WATER LEVELS WERE
NOT MEASURED FOR BG -105, MW -215, MW -225, GWA-205,
OR GWA-175. WATER TABLE SYMBOLOGY IS PRESENTED
BELOW.
- �-
2. RECOVERY (REC) AND ROCK QUALITY DESIGNATION (RQD) ARE
MEASUREMENTS OF THE QUALITY OF ROCK CORE RECOVERED
FROM A BOREHOLE.
3. STANDARD PENETRATION TESTING (SPT), REC AND RQD WERE
THE PRIMARY SOURCES OF DATA USED IN THE
DETERMINATION/ASSIGNMENT OF HYDROSTRATIGRAPHIC LAYERS
TO NATURAL MATERIALS (ALLUVIUM, SOIL, SAPROLITE, AND
ROCK) IN A BOREHOLE; REVIEWS OF THE BOREHOLE LOGS,
FIELD PHOTOGRAPHS, AND GEOLOGIC JUDGMENT WERE ALSO
