CROSS SECTION NOTES:
1. GROUND WATER LEVEL MEASUREMENTS WERE TAKEN ON JUNE
16, 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, WATER TABLE SYMBOLOGY IS
PRESENTED BELOW. WHERE WATER TABLE SYMBOL IS NOT
PRESENT, NO MEASUREMENT OCCURRED AND WATER TABLE IS
ESTIMATED. _ 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 RQD WERE
THE PRIMARY SOURCES OF DATA USED IN THE
DETERMINATION/ASSIGNMENT OF HYD ROSTRATI GRAPH I C LAYERS
TO NATURAL MATERIALS (ALLUVIUM, SOIL, SAPROLITE AND
ROCK) IN A BOREHOLE; IN CASES WHERE SPT WAS NOT

THE HYDROSTRATIGRAPHIC LEGEND FOR MORE DETAILS.
4. ADDITIONAL CSA GROUNDWATER MONITORING WELLS WERE
INSTALLED VIA SONIC DRILLING; AS SUCH, RQD CAN NOT BE
DETERMINED DUE TO THIS DRILLING METHOD AND ARE
THEREFORE NOT PRESENTED FOR NEWLY INSTALLED WELLS.
5. TOP OF CASING IS NOT PRESENTED HEREIN FOR WELL
