Subject: Walser's Service Influent and Effluent Lead
Attachments: In-Eff Table.xlsx; 2016-08-25 Inf-Eff-MW192310308_frc.pdf
Miss Wang,
Here is a summary for the possible explanations for past lead detections in the Walser's Service influent and effluent
system samples:
Lead is a naturally occurring element in the soils in this region; it is possible that the lead being detected in the
treatment system influent and/or effluent is a natural by-product from the soils in the area leaching lead into the
groundwater of the site's area. August 25,2016, Shield sampled monitoring well MW-1 as part of routine sampling, and
included lead in the sampling analysis plan. The analytical report presented 14.4 micrograms/liter(ug/L)of lead in
monitoring well MW-1;thus adding weight to the theory of lead leaching out of the native soils into the groundwater in
the site's area (refer to laboratory attachment). Incidentally in that same sampling event no lead was detected in the
influent and effluent.
A possible explanation for the concentrations of lead in the effluent in the past could be due to a brass fitting on the
effluent sampling location. Depending on the type of brass,there are a variety of lead concentrations that can be
attributed to the chemical composition of the brass components. Shield removed a brass fitting on the effluent sample
some time in 2016. Unfortunately,this small maintenance repair was not reported and Shield does not have the exact
date of the site visit the brass fitting was removed and replaced. However it does coincide with the theory of a brass
fitting being at least part of the cause for lead in the effluent sample, considering that Shield has not had a detection of
lead in the effluent since May 26, 2016.
Shield will continue to monitor the lead situation in the influent and effluent samples, if lead concentrations become
detected Shield will undergo an investigation as to why the lead detections have reoccurred.
Refer to the Influent/Effluent table for lead concentrations from February 2013 to July 17, 2017.

HI Ayla,
Thepresentednot
data in the table does appear to be complete. For example, a report dated July 24, 2013 from Shield
Engineering indicated that both influent and effluent of the system were sampled on June 25, 2013 and lead
concentrations were 13.5 ug/L and 25.9 ug/L, respectively; however these results were not in the table. Please check
and make sure that all data collected since February 2013 are included in the table. Please explain why the
concentration at effluent was higher than influent.
It is very possible that lead is naturally occurring, but it needs to be approved by collecting upgradient background data
if lead is detected in future sampling events.
Thank you!

Subject: Lead Table and possible explanations
Miss Wang,
Attached is a summary table of historical analytical results for Walser's Service Influent and Effluent system samples.
Prior to April 21, 2016, lead was not sampled for the influent sample. The May 26, 2016 sampling event is the only
occurrence when the influent was non-detect and the effluent had a detection of lead (below 2L Standard). Since June
28, 2016 both influent and effluent samples have not had a detection of lead.
Possible explanations for the detection of lead:
• Lead is a naturally occurring element in the piedmont geology/hydrogeology
• On the effluent sample location there was a brass fitting, that has been removed (date not known, believed to
be replaced in 2016).
• A natural lead build up on the pump screens, in discussing this matter with the O&M manager, he describes the
pumps always having a "black sludge" on the pump, he continues to clean the pump but assumes the continued
"black sludge" could be located in the bottom of the well.
We will continue to sample for lead and if lead is detected in future sampling events, we can discuss and create a plan to
remediate the lead problem.

Subject: Lead Table and possible explanations
Miss Wang,
Attached is a summary table of historical analytical results for Walser's Service Influent and Effluent system samples.
Prior to April 21, 2016, lead was not sampled for the influent sample. The May 26, 2016 sampling event is the only
occurrence when the influent was non-detect and the effluent had a detection of lead (below 2L Standard). Since June
28, 2016 both influent and effluent samples have not had a detection of lead.
Possible explanations for the detection of lead:
• Lead is a naturally occurring element in the piedmont geology/hydrogeology
• On the effluent sample location there was a brass fitting, that has been removed (date not known, believed to
be replaced in 2016).
1

• A natural lead build up on the pump screens, in discussing this matter with the O&M manager, he describes the
pumps always having a "black sludge" on the pump, he continues to clean the pump but assumes the continued
"black sludge" could be located in the bottom of the well.
We will continue to sample for lead and if lead is detected in future sampling events, we can discuss and create a plan to
remediate the lead problem.

Hi Ayla and David,
We have received and reviewed the requested report.This submittal appears to meet the permit requirement for
reporting, but does not address the lead issue (see Michael email below) thoroughly. Although the Annual Report for
2016-2017 indicates that lead was not detected in June 2016 or July 2017 sampling event, it does not explain why in the
past, elevated levels of lead were detected and especially why the concentration at the effluent sometimes was higher
than that at the influent of the system. Please compile all lead concentration data collected since February 1, 2013 into
a table and submitted to this office with your explanation, why lead concentration fluctuated and sometimes the
concentration at the effluent was higher than at the influent. Whether and how this problem can be prevented in future
should be also discussed.
In addition, I would like to make a short site visit on Friday (August 4, 2017) afternoon to confirm the site current
conditions. Could you please meet me at the site at 2:00 pm? If this date or time does not work for you, next Monday
will be fine with me as well. Please just let me know.
If you have any questions, please just let me know.Thank you!

Standards prior to discharge to the injection well. The treated water discharged into the injection well
must not cause a violation of Class GA Standards for any constituent beyond the Compliance Boundary,
nor cause the migration of the contamination into unaffected areas. If the treatment system fails to
consistently achieve this standard, additional treatment units or changes in operational needs may be
required.
2. This permit shall become voidable if the soils fail to adequately assimilate the remaining wastes and may
be rescinded unless the facilities are installed, maintained, and operated in a manner, which will protect
the assigned water quality standards of the surface and groundwaters.
3. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface or
groundwaters resulting from the operation of this facility.

discharge of any wastewater resulting from the operation of this facility. The groundwater recovery,
treatment and disposal system shall be inspected monthly. If it is determined that the system is
malfunctioning or leading to the release of wastes to the environment, a threat to human health, or a
nuisance, all repairs should be made as soon as possible and reported to the Winston-Salem Regional
Office (see Section V. NONCOMPLIANCE NOTIFICATION). All components of the groundwater
recovery, treatment, and disposal system shall be properly weatherproofed to prevent freezing and failure
of the system.

5. The Permittee shall maintain an inspection log or summary including at least the date and time of
inspection, observations made, and any maintenance, repairs, or corrective actions taken by the Permittee.
This log of inspections shall be maintained by the Permittee for a period of three years from the date of
the inspection and shall be made available to the Division or other permitting authority, upon request.
6. Any duly authorized officer, employee, or representative of the Division may, upon presentation of
credentials, enter and inspect any property, premises or place on or related to the disposal site or facility at
any reasonable time for the purpose of determining compliance with this permit, may inspect or copy any
records that must be maintained under the terms and conditions of this permit, and may obtain samples of
groundwater, surface water, or leachate.
III. MONITORING REQUIREMENTS
1. The effluent from the treatment system shall be sampled annually for the parameters specified below:
EPA Methods 601 and 602 (with IPE, MTBE, EDR, Xylenes, and Massachusetts Department of
Environmental Protection volatile Petroleum Hydrocarbons(MADEP VHP)and lead(3030C prep))

Shield Project 1990018
Dear Ms. Wang:
Shield Engineering, Inc. (Shield) is pleased to submit this annual report summarizing the effluent
discharged into the injection well during the reporting period of January 1, 2016 through July 17,
2017. Based on the Non-discharge Permit WQ0015102, the annual report should contain the
following:
• Volume and injection pressures of effluent discharged into the injection well
• The summary results of related groundwater, influent, and effluent monitoring
• Isoconcentration and water level contour maps
The Air Sparge(AS),Soil Vapor Extraction(SVE),and Groundwater Recovery System(GRS)was
installed and commenced operation on January 28, 1999. The AS system includes two 2-inch
diameter sparge wells (AI-1 and AI-2). Groundwater is recovered from one vapor enhanced
groundwater dual phase recovery well (VERW-1). The recovered groundwater is treated using a
low-profile air stripper and granular activated carbon. Treated groundwater is then discharged to
injection well MW-3.
Approximately 141,585 gallons of groundwater was treated and discharged into the injection well
between January 1, 2016 and July 17, 2017. The injection pressure at monitoring well MW-3 has
not exceeded zero pounds per square inch (psi) since installation of the pressure gauge in October
2016.
As required by the non-discharge permit, influent and effluent samples are collected and submitted
for laboratory analysis annually, with the most recent sampling event occurring on July 17, 2017.
The summary of GRS data,analytical results,and mass of total contaminants removed are presented
in Table 1. As shown in Table 1, no analyzed petroleum constituents or lead were detected in the
effluent sample during the July 2017 sampling event, indicating the treatment system is effectively
removing contaminants. Lead has not been detected in the influent or effluent since June 2016. The
mass of BTEX (benzene, toluene, ethylbenzene, and total xylenes) contaminants removed is

presented in Table 2.
Site wide sampling of monitoring wells MW-1, MW-2, and MW-4 through MW-9 is conducted
semi-annually in May and November of each year with semi-annual monitoring reports and
corrective action performance reports being submitted to the North Carolina Department of
Environmental Quality (NCDEQ) Winston-Salem Regional Office in June and December of each
year. As shown in Table 3 — Summary of Historical Analytical Results, two monitoring wells had
one constituent above the 15A NCAC 2L Groundwater Standards (2L Standards) during the last
sampling event. Monitoring wells MW-1 and MW-2 had naphthalene above the 2L Standard.
Attached are Figure 4 (Groundwater Elevation Contour Map) and Figure 5 (Naphthalene
Isoconcentration Map) from the June 28, 2017 Monitoring Report. The groundwater elevation
isocontours fluctuate depending on the pumping or vacuuming by the treatment system at the time.
If you should have any questions, please contact the undersigned at(704) 394-6913.
