SOURCES:
1. THE TOPOGRAPHY SURVEY DATA WITHIN THE PROPERTY
BOUNDARY DATED APRIL 17, 2014 WAS OBTAINED FROM
WSP OF CARY, NORTH CAROLINA.
2. 2ft CONTOUR INTERVALS BEYOND THE PROPERTY
BOUNDARY ARE FROM NCDOT LIDAR DATED 2007
https://connect.ncdot.gov/resources/gis/pages/cont-elev_v2.aspx
3. SELECT TOPOGRAPHIC ADJUSTMENTS BASED ON SITE
SURVEY AND COMPARISON TO AERIAL PHOTOGRAPH.
4. 2015 LITHOLOGY INFORMATION OF SOIL AND WELL LOG
TOPOGRAPHY IS FROM SYNTERRA.
NOTE:
1. CROSS SECTION LOCATIONS SHOWN ON FIGURE 2-1.
2. WATER LEVELS WERE COLLECTED BY SYNTERRA ON
JUNE 29, 2015.
3. IMAC VALUE FOR COBALT IS 1 μg/L.

NOTE: 10:1 VERTICAL EXAGGERATION
SOURCES:
1. THE TOPOGRAPHY SURVEY DATA WITHIN THE PROPERTYBOUNDARY DATED APRIL 17, 2014 WAS OBTAINED FROM
WSP OF CARY, NORTH CAROLINA.
2. 2ft CONTOUR INTERVALS BEYOND THE PROPERTY
BOUNDARY ARE FROM NCDOT LIDAR DATED 2007
https://connect.ncdot.gov/resources/gis/pages/cont-elev_v2.aspx
3. SELECT TOPOGRAPHIC ADJUSTMENTS BASED ON SITE
SURVEY AND COMPARISON TO AERIAL PHOTOGRAPH.
4. 2015 LITHOLOGY INFORMATION OF SOIL AND WELL LOG
TOPOGRAPHY IS FROM SYNTERRA.
NOTE:
1. CROSS SECTION LOCATIONS SHOWN ON FIGURE 2-1.
2. WATER LEVELS WERE COLLECTED BY SYNTERRA ON
JUNE 29, 2015.
3. 2L VALUE FOR IRON IS 300 μg/L.

Notes:
Bold color highlighted concentrations indicate highest exceedance of the EPA Mid-Atlantic Risk Assessment regional screening levels for soil, June 2015, for the category listed below:
- Soil RSL - Industrial Health
- Soil RSL - Residential Health
- Soil RSL - Protection of Groundwater
mg/kg = milligrams per kilogram
NE = Not established
Std. Units = Standard Units
% = Percent
j = indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated.
< = concentration not detected at or above the reporting limit.

Notes:
Bold color highlighted concentrations indicate highest exceedance of the EPA Region 9 Regional Screening Level Summary Table, June 2015, for the category listed below:
- Soil RSL - Industrial Health
- Soil RSL - Residential Health
- Soil RSL - Protection of Groundwater
mg/kg = milligrams per kilogram
NE = Not established
S.U. = Standard Units
% = Percent
j = indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated.
< = concentration not detected at or above the reporting limit.
