NOTES
1. TOPOGRAPHIC CONTOUR INTERVAL = 2 FEET
2. GROUNDWATER SURFACE CONTOUR INTERVAL = 5 FEET
3. GROUNDWATER ELEVATIONS MEASURED ON OCTOBER 7, 2015.
4. GROUNDWATER CONTOURS BASED ON LINEAR INTERPOLATION BETWEEN AND
EXTRAPOLATION FROM KNOWN DATA, TOPOGRAPHIC CONTOURS, AND KNOWN FIELD
CONDITIONS. THEREFORE, GROUNDWATER CONTOURS MAY NOT REFLECT ACTUAL
CONDITIONS.
5. GROUNDWATER CONTOUR LINES SHOW THE WATER TABLE SHAPE AND ELEVATION. THESE
CONTOURS ARE INFERRED LINES FOLLOWING THE GROUNDWATER SURFACE AT A
CONSTANT ELEVATION ABOVE SEA LEVEL. THE GROUNDWATER FLOW DIRECTION IS
GENERALLY PERPENDICULAR TO THE GROUNDWATER SURFACE CONTOURS, SIMILAR TO THE
RELATIONSHIP BETWEEN SURFACE WATER FLOW AND TOPOGRAPHIC CONTOURS.
6. PROPERTY BOUNDARY SURVEY BY JAMES L. WRIGHT DATED NOVEMBER 1984. ITS LOCATION
IS RELATIVE TO TOPOGRAPHY APPROXIMATE BY HDR ENGINEERING, INC.
7. EXISTING TOPOGRAPHY WITHIN ACTIVE AND PROPOSED LANDFILL PROVIDED BY MATTHEWS
LAND SURVEYING & MAPPING, PLLC DATED APRIL 17, 2015.
8. MONITORING WELLS MW-1 THROUGH MW-5 SURVEYED JUNE 1987 BY S&ME, INC. MONITORING
WELLS MW-6 THROUGH MW-16 SURVEYED APRIL 1995, SEPTEMBER 1996, AND APRIL 2003 BY
HDR ENGINEERING INC./ ED BUCKNER RLS APRIL 17, 2015.
9. THE LOCATIONS OF LANDFILL GAS TRENCH VENTS ARE APPROXIMATE.
10. GROUNDWATER WELLS MW-11D, MW-13D, AND MW-16D ARE NOT SCREENED IN THE SHALLOW
AQUIFER AND ELEVATION DATA WERE NOT USED IN THE CONSTRUCTION OF GROUNDWATER
CONTOURS.
11. A STREAM DETERMINATION WAS CONDUCTED ON APRIL 17, 2013 BY A GOLDER ASSOCIATES
NC, INC. REPRESENTATIVE. THE STREAM DETERMINATION WAS CONDUCTED USING NCDWQ'S
"METHODOLOGY FOR IDENTIFICATION OF INTERMITTENT AND PERENNIAL STREAMS AND
THEIR ORIGINGS, VERSION 4.11".
