listed in Table VIU of Standard Method 6230D. Any method used must provide a PQL of 0.5
ug/L or less, which must be supported by laboratory proficiency studies as required by the DWQ
Laboratory Certification Unit. Any constituents detected above the Method Detection Limit
(MDL) but below the PQL of 0.5 ug/L must be qualified (estimated) and reported.
c. Any laboratory selected to analyze parameters must be Division of Water Quality (DWQ) certified
for those parameters required.
3. System Operation Requirements:
a. The groundwater recovery, treatment and disposal system shall be inspected weekly. If it is
determined that the system is malfunctioning, all repairs should be made as soon as possible and
reported to the Winston-Salem Regional Office within 48 hours. All components of the
groundwater recovery, treatment, and disposal system shall be properly weather -proofed to
