1. GROUND WATER LEVEL MEASUREMENTS WERE TAKEN ON MAY 9, 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 LEVEL MEASUREMENTS WERE NOT TAKEN ON MAY 9, 2016 FOR GWA-4S, MW-200S,
GWA-26S, AND GWA-27S. 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 HYDROSTRATI GRAPHIC LAYER BASED ON A REVIEW OF THE BOREHOLE LOG, FIELD PHOTOGRAPHS, AND
GEOLOGIC JUDGMENT. PLEASE REFER TO THE HYDROSTRATI GRAPHIC LEGEND FOR MORE DETAILS.
4. ADDITIONAL CSA GROUNDWATER MONITORING WELLS WERE INSTALLED VIA SONIC DRILLING; AS SUCH, ROD
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 CONSTRUCTION GRAPHICS. PLEASE SEE APPENDIX H
OF THE COMPREHENSIVE SITE ASSESSMENT (AUGUST, 2015) AND APPENDIX A OF CSA SUPPLEMENT 2 FOR
WELL CONSTRUCTION RECORDS AND GEOLOGIC BORING LOGS.
6. BEDROCK (BR —DESIGNATED) WELLS WERE SCREENED ACROSS INTERPRETED WATER —BEARING FRACTURE
ZONES BASED ON EXAMINATION OF THE ROCK CORE AND ROCK PACKER TESTING WHERE PERFORMED.
