Notes:
- Bold highlighted concentration indicates exceedance of the 15A NCAC 02L Standard, Appendix 2, April 1, 2013.
ORP = Oxidation Reduction Potential Deg C = Degree Celsius mV = millivolts ug/l = microgram per liter
DIS = Dissolved mg/l = milligrams per liter NM = Not Measured umhos/cm = micro mhos per centimeter
TOT = Total mg-N/L = miligram nitrogen per liter NTU = nephelometric turbidity unit Spec Cond = Specific Conductance
Temp = Temperature DUP=Duplicate S.U. = Standard Unit ft = feet
DO = Dissolved Oxygen Note 1: If analytical method detection limit or concentration exceeds soil RSL
< = concentration not detected at or above the reporting limit.Note 2: If no soil RSL
--- = not applicable
* = Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April 1, 2013.

Notes:
- Bold highlighted concentration indicates exceedance of the 15A NCAC 02L Standard, Appendix 2, April 1, 2013.
ORP = Oxidation Reduction Potential Deg C = Degree Celsius mV = millivolts ug/l = microgram per liter
DIS = Dissolved mg/l = milligrams per liter NM = Not Measured umhos/cm = micro mhos per centimeter
TOT = Total mg-N/L = miligram nitrogen per liter NTU = nephelometric turbidity unit Spec Cond = Specific Conductance
Temp = Temperature DUP=Duplicate S.U. = Standard Unit ft = feet
DO = Dissolved Oxygen Note 1: If analytical method detection limit or concentration exceeds soil RSL
< = concentration not detected at or above the reporting limit.Note 2: If no soil RSL
--- = not applicable
* = Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April 1, 2013.

Notes:
0 - Bold highlighted concentration indicates exceedance of the 15A NCAC 02L Standard, Appendix 2, April 1, 2013.
ORP = Oxidation Reduction Potential Deg C = Degree Celsius mV = millivolts
DIS = Dissolved mg/I = milligrams per liter NM = Not Measured
TOT = Total mg-N/L = miligram nitrogen per liter NTU = nephelometric turbidity unit
Temp = Temperature DUP=Duplicate S.U. = Standard Unit
DO = Dissolved Oxygen
< = concentration not detected at or above the reporting limit.
--- = not applicable
= Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April 1, 2013.
Prepared by: BE LAM Checked by: RAG
ug/I = microgram per liter
umhos/cm = micro mhos per centimeter
Spec Cond = Specific Conductance
ft = feet
Note 1: If analytical method detection limit or concentration exceeds soil RSL
Note 2: If no soil RSL

Prepared by: BER LAM Checked by: RAG
Notes:
0 - Bold highlighted concentration indicates exceedance of the 15A NCAC 02L Standard, Appendix 2, April 1, 2013
ORP = Oxidation Reduction Potential
Deg C = Degree Celsius
mV = millivolts
ug/I = microgram per liter
DIS = Dissolved
mg/I = milligrams per liter
NM = Not Measured
umhos/cm = micro mhos per centimeter
TOT = Total
mg-N/L = miligram nitrogen per liter
NTU = nephelometric turbidity unit
Spec Cond = Specific Conductance
Temp = Temperature
DUP=Duplicate
S.U. = Standard Unit
ft = feet
DO = Dissolved Oxygen
Note 1: If analytical method detection limit
or concentration exceeds soil RSL
< = concentration not detected at or above
the reporting limit.
Note 2: If no soil RSL
--- = not applicable
= Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix
1, April 1, 2013.
