Notes:
Q - Bold highlighted concentration indicates exceedance of the 15A NCAC 02L Standard, Appendix 2, April 1, 2013.
Deg C = Degrees Celsius mV = Millivolts mg/L = Milligram per liter ORP = Oxidation Reduction Potential DO = Dissolved oxygen
DUP = Duplicate NA = Not analyzed ug/L = Microgram per liter umhos/cm = Micro mhos per centimeter NE = Not established
S.U. = Standard Unit Temp = Temperature Spec Cord = Specific Conductance NTU = Nephelometric turbidity unit ft = Feet
< = Concentration not detected at or above the reporting limit
* = 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. Target analyte concentration in sample is less than 10x the concentration in the method blank.
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.
L3 = Analyte recovery in the laboratory control sample (LCS) exceeded QC limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
M1 = Matrix Spike Recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery
M4 = The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level.
S = Associated calibration check did not meet specified criteria.
= NC DHHS Health Screening Level.
NM = Not measured
Eh = Redox Potential

Notes:
Q - Bold highlighted concentration indicates exceedance of the 15A NCAC 02L Standard, Appendix 2, April 1, 2013.
Deg C = Degrees Celsius my = Millivolts mg/L = Milligram per liter ORP = Oxidation Reduction Potential DO = Dissolved oxygen
DUP = Duplicate NA = Not analyze ug/L = Microgram per liter umhos/cm = Micro mhos per centimeter NE = Not established
S.U. = Standard Unit ft = Feet Temp = Temperature Spec Cond = Specific Conductance NM = Not measured
Eh = Redox Potential
NTU = Nephelometric turbidity unit
= NC DHHS Health Screening Level
< = Concentration not detected at or above the reporting limit
= Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April 1, 2013.
j = Indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated.
B = Target analyte detected in method blank at or above the reporting limit. Target analyte concentration in sample is less than 10x the concentration in the method blank.
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 complicance purposes.
D6 = The relative percent difference (RPD) between the sample and sample duplicate exceeded laboratory control limits.
-1 = Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results may be biased high.
L3 = Analyte recovery in the laboratory control sample (LCS) exceeded QC limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
MI = Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
M6 = Matrix spike and matrix spike duplicate recovery not evaluated against control limits due to sample dilution.

Notes:
Q - Bold highlighted concentration indicates exceedance of the 15A NCAC 02L Standard, Appendix 2, April 1, 2013.
Deg C = Degrees Celsius my = Millivolts mg/L = Milligram per liter ORP = Oxidation Reduction Potential DO = Dissolved oxygen
DUP = Duplicate NA = Not analyzed ug/L = Microgram per liter umhos/cm = Micro mhos per centimeter NE = Not established
S.U. = Standard Unit ft = Feet mg - N/L = Milligram nitrogen per liter Spec Cond = Specific Conductance NM = Not measured
< = Concentration not detected at or above the reporting limit
= 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. Target analyte concentration in sample is less than 10x the concentration in the method blank.
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.
D6 = The relative percent difference (RPD) between the sample and sample duplicate exceeded laboratory control limits.
j = Indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated.
Ll = Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results may be biased high.
L3 = Analyte recovery in the laboratory control sample (LCS) exceeded QC limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
M1 = Matrix Spike Recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
M2 = Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.
S = Associated calibration check did not meet specified criteria.
NTU = Nephelometric turbidity unit
Temp = Temperature
= NC DHHS Health Screening Level.

Notes:
Q- Concentration exceeds the 15A NCAC 02L Standard, Appendix 2, April 1, 2013 or provisional background concentration (whichever is greater).
Deg C = Degrees Celsius mV = Millivolts mg/L = Milligram per liter ORP = Oxidation Reduction Potential DO = Dissolved oxygen
DUP = Duplicate NA = Not analyzed ug/L = Microgram per liter umhos/cm = Micro mhos per centimeter NE = Not established
S.U. = Standard Unit Temp = Temperature Spec Cond = Specific Conductance NTU = Nephelometric turbidity unit ft = Feet
< = Concentration not detected at or above the reporting limit
* = 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. Target analyte concentration in sample is less than 10x the concentration in the method blank.
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.
L3 = Analyte recovery in the laboratory control sample (LCS) exceeded QC limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
M1 = Matrix Spike Recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery
M4 = The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level.
S = Associated calibration check did not meet specified criteria.
= NC DHHS Health Screening Level.
NM = Not measured
Eh = Redox Potential

Prepared by: BER Checked by: TDP/MCD
Notes:
0 - Concentration exceeds the 15A NCAC 02L Standard, Appendix 2, April 1, 2013 or provisional background concentration (whichever is greater).
Deg C = Degrees Celsius my = Millivolts mg/L = Milligram per liter ORP = Oxidation Reduction Potential DO = Dissolved oxygen
DUP = Duplicate NA = Not analyze ug/L = Microgram per liter umhos/cm = Micro mhos per centimeter NE = Not established
S.U. = Standard Unit ft = Feet Temp = Temperature Spec Cord = Specific Conductance NM = Not measured
Eh = Redox Potential
NTU = Nephelometric turbidity unit
= NC DHHS Health Screening Level
< = Concentration not detected at or above the reporting limit
= Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April 1, 2013.
j = Indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated.
B = Target analyte detected in method blank at or above the reporting limit. Target analyte concentration in sample is less than 10x the concentration in the method blank.
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 complicance purposes.
D6 = The relative percent difference (RPD) between the sample and sample duplicate exceeded laboratory control limits.
-1 = Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results may be biased high.
L3 = Analyte recovery in the laboratory control sample (LCS) exceeded QC limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
M1 = Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
M6 = Matrix spike and matrix spike duplicate recovery not evaluated against control limits due to sample dilution.

Notes:
Q - Concentration exceeds the 15A NCAC 02L Standard, Appendix 2, April 1, 2013 or provisional background concentration (whichever is greater).
Deg C = Degrees Celsius my = Millivolts mg/L = Milligram per liter ORP = Oxidation Reduction Potential DO = Dissolved oxygen
DUP = Duplicate NA = Not analyzed ug/L = Microgram per liter umhos/cm = Micro mhos per centimeter NE = Not established
S.U. = Standard Unit ft = Feet mg - N/L = Milligram nitrogen per liter Spec Cond = Specific Conductance NM = Not measured
< = Concentration not detected at or above the reporting limit
= 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. Target analyte concentration in sample is less than 10x the concentration in the method blank.
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.
D6 = The relative percent difference (RPD) between the sample and sample duplicate exceeded laboratory control limits.
j = Indicates concentration reported below Practical Quantitation Limit (PQL), but above Method Detection Limit (MDL) and therefore concentration is estimated.
Ll = Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results may be biased high.
L3 = Analyte recovery in the laboratory control sample (LCS) exceeded QC limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
MI = Matrix Spike Recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
M2 = Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.
S = Associated calibration check did not meet specified criteria.
NTU = Nephelometric turbidity unit
Temp = Temperature
= NC DHHS Health Screening Level.

Notes:
= - Concentration exceeds the 15A NCAC 02L Standard, Appendix 2, April 1, 2013 or provisional background concentration (whichever is greater)
Spec Cord = Specific Conductance
Deg C = Degrees Celsius
NTU = Nephelometric turbidity unit
DUP
= Duplicate
umhos/cm = Micro mhos per centimeter
NE = Not established
S.U.
= Standard Unit
mg/L = Milligram per liter
DO = Dissolved oxygen
ft =
Feet
mV = Millivolts
ORP = Oxidation Reduction Potential
NA =
Not analyzed
ug/L = Microgram per liter
= NC DHHS Health Screening Level
NM
= Not measured
Temp = Temperature
Eh = Redox Potential
< = Concentration not detected at or above the reporting limit
= 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. Target analyte concentration in sample is less than 10x the concentration in the method blank.
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.
D3 = Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
Ll = Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results may be biased high.
L3 = Analyte recovery in the laboratory control sample (LCS) exceeded QC limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
M1 = Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
S = Associated calibration check did not meet specified criteria.
= 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.
Data not used in provisional background concentration determinations.
