CROSS SECTION NOTES:
1. GROUND WATER LEVEL MEASUREMENTS WERE TAKEN ON JUNE 22,
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. NO WATER LEVEL
MEASUREMENTS WERE TAKEN FOR MW-11 CLUSTER AND GWA-12
CLUSTER.. WATER TABLE SYMBOLOGY IS PRESENTED BELOW.
2. RECOVERY (REC) AND ROCK QUALITY DESIGNATION (ROD) 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; IN CASES WHERE SPT
WAS NOT PERFORMED AND WHERE REC AND/OR ROD DATA WERE
UNAVAILABLE DUE TO DRILLING METHOD, THE NATURAL MATERIALS
WERE ASSIGNED TO A HYD ROSTRATI GRAPH I C LAYER BASED ON A
REVIEW OF THE BOREHOLE LOG, FIELD PHOTOGRAPHS, AND GEOLOGIC
JUDGMENT. PLEASE REFER TO THE HYDROSTRATIGRAPHIC LEGEND FOR
MORE DETAILS.
