Notes:
- Bold highlighted concentration indicates exceedance of the 15A NCAC 02L Standard, Appendix 2, April 1, 2013
ug/L = microgram per liter NTU = nephelometric turbidity unit
mg/L = milligrams per liter
Eh = Redox potential S.U. = Standard Unit
my = millivolts
NE = Not Established umhos/cm = micro mhos per centimeter
Deg C = Degree Celsius
DUP = Duplicate DO = Dissolved Oxygen
ft = feet
Spec Cond = Specific Conductance ORP = Oxidation Reduction Potential
NO = Not Detected
Temp = Temperature NM = Not Measured
NA = Not Analyzed
mg - N/L = Milligram nitrogen per liter
< = concentration not detected at or above the reporting limit.
= NC DHHS Health Screening Level
* = Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April, 1, 2013.
B2 = Target analyte was detected in blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit.
D3 = Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
M1 = Matrix spike recovery exceeds QC limits.
M2 = Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.

Notes:
- Bold highlighted concentration indicates exceedance of the 15A NCAC 02L Standard, Appendix 2, April 1, 2013
ug/L = microgram per liter NTU = nephelometric turbidity unit
mg/L = milligrams per liter
Eh = Redox potential S.U. = Standard Unit
mV = millivolts
NE = Not Established umhos/cm = micro mhos per centimeter
Deg C = Degree Celsius
DUP = Duplicate DO = Dissolved Oxygen
ft = feet
Spec Cond = Specific Conductance ORP = Oxidation Reduction Potential
ND = Not Detected
Temp = Temperature NM = Not Measured
NA = Not Analyzed
< = concentration not detected at or above the reporting limit.
= NC DHHS Health Screening Level
= Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April, 1, 2013.
b = Target analyte detected in method blank at or above the reporting limit.
D3 = Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
M1 = Matrix spike recovery exceeds QC limits.
B2 = Target analyte was detected in blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting
limit.

Notes:
n - Bold highlighted concentration indicates exceedance of the 15A NCAC 02L Standard, Appendix 2, April 1, 2013.
Spec Cond = Specific Conductance
Deg C = Degrees Celsius
ND = Not detected
Eh = Redox Potential
S.U. = Standard Unit
ug/L = Microgram per liter
NE = Not established
umhos/cm = Micro mhos per centimeter
ft = Feet
mg/L = Milligram per liter
DO = Dissolved oxygen
ORP = Oxidation Reduction Potential
NA = Not analyzed
my = Millivolts
Temp = Temperature
NM = Not measured
NTU = Nephelometric turbidity unit
< = Concentration not detected at or above
the reporting limit
^ = NC DHHS Health Screening Level
* = Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April 1, 2013.
B2 = Target analyte was detected in blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
M1 = Matrix spike recovery was high: the associated Laboratory Control Spike (LCS) was acceptable.
M4 = The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level.

Notes:
- Concentration greater than the Federal MCL (https://www.epa.gov/sites/production/files/2016-06/documents/npwdr_complete_table.pdf)
< = concentration not detected at or above reporting limit
j = Indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated.
RL = reporting limit
pCi/L = picocuries per liter
ug/mL = micrograms per milliliter

Notes:
- Concentration exceeds the 15A NCAC 02L Standard, Appendix 2, April 1, 2013 or provisional background concentration (whichever is greater).
ug/L = microgram per liter NTU = nephelometric turbidity unit mg/L = milligrams per liter
Eh = Redox potential S.U. = Standard Unit mV = millivolts
NE = Not Established umhos/cm = micro mhos per centimeter Deg C = Degree Celsius
DUP = Duplicate DO = Dissolved Oxygen ft = feet
Spec Cond = Specific Conductance ORP = Oxidation Reduction Potential ND = Not Detected
Temp = Temperature NM = Not Measured NA = Not Analyzed
mg - N/L = Milligram nitrogen per liter
< = concentration not detected at or above the reporting limit.
^ = NC DHHS Health Screening Level
+ = Chromium (VI) speciation samples were analyzed using IC-ICP-DRC-MS method as opposed to ICP-MS method and were not analyzed in background wells. Chromium (VI) PBC is
based on background samples analyzed using ICP-MS method. Therefore, Chromium (VI) PBC is used for comparison only to speciation analytical results.
* = Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April, 1, 2013.
B2 = Target analyte was detected in blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit.
M1 = Matrix spike recovery exceeds QC limits.
M2 = Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.

0 - Concentration exceeds the 15A NCAC 02L Standard, Appendix 2, april 1, 2013 or provisional background concentration (whichever is greater)
ug/L = microgram per liter
NTU
= nephelometric turbidity unit
mg/L = milligrams per liter
Eh = Redox potential
S.U.

ft = feet
Spec Cord = Specific Conductance
ORP
= Oxidation Reduction Potential
ND = Not Detected
Temp = Temperature
NM =

NA = Not Analyzed
< = concentration not detected at or above the reporting limit.
= NC DHHS Health Screening Level
+ = Chromium (VI) speciation samples were analyzed using IC-ICP-DRC-MS method as opposed to ICP-MS method and were not analyzed in background wells. Chromium (VI) PBC is
based on background samples analyzed using ICP-MS method. Therefore, Chromium (VI) PBC is used for comparison only to speciation analytical results.
= Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April, 1, 2013.
b = Target analyte detected in method blank at or above the reporting limit.
B2 = Target analyte was detected in blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit.
D3 = Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
M1 = Matrix spike recovery exceeds QC limits.
