be submitted after the established due date? ..
2 Was any required information missing on the GW-59 report forms? YES( NO
IF the answer to question 1 or 2 is"YES",list in the space provided below the well identification number(s)and explain the \\problems encountered in obtaining the required information.
3 Are any of the monitor wells in need of repair or maintenance(damaged casing,unlocked or missing cap,missing identificat n YES NO
plate,area overgrown,etc.)?If the answer is"Yes",contact the Regional Office,for guidance. Some wells need locks and
protective casings.
4 Are any monitored constituents equal to or above the established standards? YES NO
If the answer to question 4 is"NO",skip to section 8.
If the answer to question 4 is"YES"list the affected wells individually with constituent(s)and concentration(s)
exceeding standards in the space provided below: pH for all monitor wells sampled was below the range of 6.5-8.5
SU.
5 For the constituents identified in question 4 above,have standards been exceeded previously for the same ( YES ) NO
constituent(s)in the same well(s)in the last two years? ` /
If the answer to question 5 is"NO",skip to section 8.
If the answer to question 5 is"YES",list in the space provided below,each well with constituent(s)exceeding
standards,concentration(s)reported,and sample collection date for each occurrence(for the last two years).
All MW's had a pH less than 6.5 SU in previous sampling events.
6 Are the monitoring wells listed in section 5 located at or beyond the review boundary? YES( NO
If the answer is"YES",a groundwater quality problem maybe occurring.CONTACT THE REGIONAL OFFICE

QUALIFIERS
Project: CPC Greensboro 216623
Pace Project No.: 92552615
DEFINITIONS
DF-Dilution Factor, if reported,represents the factor applied to the reported data due to dilution of the sample aliquot.
ND-Not Detected at or above adjusted reporting limit.
TNTC-Too Numerous To Count
J-Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL-Practical Quantitation Limit.
RL-Reporting Limit-The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate%recovery and RPD values.
LCS(D)-Laboratory Control Sample(Duplicate)
MS(D)-Matrix Spike(Duplicate)
DUP-Sample Duplicate
RPD-Relative Percent Difference
NC-Not Calculable.
SG-Silica Gel-Clean-Up
U-Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis ofAcrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited.Contact your Pace PM for the current list of accredited analytes.
TNI-The NELAC Institute.
ANALYTE QUALIFIERS
IK The recalculated concentration of the calibration standard(s)did not meet method acceptance criteria;this result should
be considered an estimated value.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample(LCS)recovery.
R1 RPD value was outside control limits.
v2 The continuing calibration verification was below the method acceptance limit.The analyte was not detected in the
associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.

QUALIFIERS
Project: CPC-Guilford County-Orphan
Pace Project No.: 92552838
DEFINITIONS
DF-Dilution Factor, if reported,represents the factor applied to the reported data due to dilution of the sample aliquot.
ND-Not Detected at or above adjusted reporting limit.
TNTC-Too Numerous To Count
J-Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL-Practical Quantitation Limit.
RL-Reporting Limit-The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate%recovery and RPD values.
LCS(D)-Laboratory Control Sample(Duplicate)
MS(D)-Matrix Spike(Duplicate)
DUP-Sample Duplicate
RPD-Relative Percent Difference
NC-Not Calculable.
SG-Silica Gel-Clean-Up
U-Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis ofAcrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited.Contact your Pace PM for the current list of accredited analytes.
TNI-The NELAC Institute.
ANALYTE QUALIFIERS
IK The recalculated concentration of the calibration standard(s)did not meet method acceptance criteria;this result should
be considered an estimated value.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample(LCS)recovery.
R1 RPD value was outside control limits.
v2 The continuing calibration verification was below the method acceptance limit.The analyte was not detected in the
associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.
v3 The continuing calibration verification was below the method acceptance limit.Any detection for the analyte in the
associated samples may have low bias.
