Jenny,
Thank you for helping with clarifying our future actions for the referenced storm water containment area. As we discussed:
1. Arsenic has been identified in the lake bottom sediments as part of recent dredging operations in concentrations
greater than its Industrial/Commercial Health Based Remediation Goals.
2. Material removed from the lake has not been found to contain Arsenic above action limits.
3. No evidence of Arsenic was found in the groundwater beneath the disposal area, nor in the lake water.
I am sending the following three reports in three separate emails due to their size:
June 17, 2008 - Soil and Environmental Consultants, PA's Sediment Sampling and Water Table Assessment
October 9 2017 - ECS Southeast, LLP's Geotechnical Engineering Report
October 17, 2017 - ARM's Carolina Lake and WWTP Property Sampling Results
We feel confident that the material that has been removed is not, nor will not cause health risks due to Arsenic
concentrations. Our only remaining concern is focused on the material still in the bottom of the lake.
Let me know if you have questions. I look forward to hearing back.

Carolina Beach Lake Maintenance Project
Scoping Meeting Project Narrative
Town of Carolina Beach, North Carolina
Purpose and Need:
The Town of Carolina Beach is seeking guidance, from the regulatory agencies, on federal and state
permits that may be required to perform maintenance, dredging/excavation operations in Carolina Beach
Lake. The purpose of the proposed maintenance work is to increase the storage capacity of the lake,
which is necessary for the following reasons:
1. An increased depth will provide greater storage capacity of the lake and improve infiltration rates,
which is necessary for flood control and prevention of the main thoroughfare (US421) and
residential and commercial structures surrounding the lake;
2. The increased water depth will allow the Town of Carolina Beach flexibility in the amount of
pumping they can do without thoroughly dewatering the feature; and
3. The removal of sediment is anticipated to enhance the physical, biological, and chemical
functions of the feature.
Location:
Carolina Beach Lake is located on the west side of Lake Park Boulevard; just past the downtown area of
Carolina Beach and just south of Atlanta Avenue (see Appendix A).
Existing Conditions:
Carolina Lake is an old salt marsh/lagoon that encompasses approximately 11.5 acres. The feature
became an isolated surface water body long before the area was developed. Today the lake is surrounded
by development (i.e., commercial and residential building, walking path, roadways, and infrastructure).
The impoundment serves several functions. First, it is an amenities feature for the residents and visitors of
the island. Second, the lake provides some flood control for the surrounding area. And lastly, the feature
traps sediments and pollutants, which are carried by stormwater swales and pipes to the lake, before they
can discharge into the ocean or Carolina Beach Harbor.
The depth of water in the lake is approximately 18". Based on the features position in the landscape, the
formation of the feature and visual inspection, during periods when the lake has been drained, the
substrate appears to be comprised of fine silt and organic material. As a result of a stormwater discharge
pipe, located on the eastern side of the lake, a sediment plume has formed, allowing hydrophytic
vegetation to emerge (see Appendix A).
Soil & Environmental Consultants, PA (S&EC), in coordination with the Town of Carolina Beach, the
NC Department of Natural Resources (DENR) and the USACE developed a sediment sampling program
that would provide data on the presence of RCRA metals and semi -volatile organic compounds.
According to the report, the sampled sediment did contain concentrations of several of the RCRA metals,
but the concentrations were ruled as naturally occurring and not indicative of gross contamination. One
compound was detected in the semi-volatiles analysis (bis-phthatate), but was found to be well below the
regulatory maximum for that compound. Shallow soil borings, on the north and south side of the lake,

(i)
produced an apparent water table of approximately 2 feet below the land surface. Please see Appendix B
for details of the report.
Project History:
The lake is a jurisdictional feature, regulated by the US Army Corps of Engineers (USACE) under
Section 404 of the Clean Water Act and Division of Water Resources (DWR). A jurisdictional
determination has not been issued for this site.
The lake is classified as SC waters and is mostly located in an AE12 flood zone (see Appendix C).
According to records obtained from the Town of Carolina Beach, the Division of Coastal Management
has determined that the feature is not tidally influenced. Over the years, the lake has become full of
sediment and other solids. In an effort to reduce flooding of the lake, the town has created additional
stormwater detention ponds, sweep the roads regularly, and maintain stormwater pipes and swales. In
addition, the town drains the lake, in advance of anticipated heavy rain events, but even this is proving to
be not enough, as the lake has very little storage capacity.
In September of 2010, the area experienced extremely heavy rains that were not associated with any
tropical storm or hurricane. The lake overflowed its banks. This caused the closure of US421, the main
arterial road through the beach community, and flooded numerous homes and businesses in the
surrounding area (see Appendix D).
Project Description:
At this time, the town estimates 6 to 10 feet of sediment will need to be removed from the bottom of the
lake. The work is not anticipated to take place within any high velocity flood (VE) zone and excavation is
not anticipated to take place within 5 foot of the normal water level. Temporary impacts to 404 wetlands,
located along the water's edge, may be necessary to gain access or perform work.
Several options, for accomplishing the desired goal, have been discussed. They are as follows:
1. Dredge material and dispose of spoil to an area within the lake;
2. Dredge and dispose a "slurry" sediment to an old equalization basin;
3. Remove and dispose a "cake" sediment to an old equalization basin; and
4. Pump the dredged material to an old equalization basin.
The spoil is anticipated to be transported or pumped to the equalization basin, which is on property owned
by Military Ocean Terminal Sunny Point (MOTSU) and located approximately 1 mile from the lake (see
Appendix E).
Purpose for the scoping meeting:
The purpose of this meeting is to discuss the logistics of the project, obtain regulatory guidance on the
environmental constraints of the work, and establish any permitting that may be required.

Re: Sediment Sampling and Water Table Assessment - Carolina Beach Lake
Dear Mr. Cox:
This letter report will document and present the results of the sediment sampling
program and a water table assessment completed by Soil & Environmental
Consultants, PA (S&EC) for a large storm water retention lake located in
Carolina Beach, N. C.
Sediment Sampling
The Carolina Beach Lake has received accumulation..of sediment over time and
the Town now desires to remove and dispose of a significant portion of this
sediment. They have previously been in contact with the N. C. Department of
Environment and Natural Resources (NCDENR) and the U. S. Army Corps of
Engineers (Corp) as to applicable regulations for potential removal and disposal
of the sediment and any associated sampling requirements.
S&EC was requested by Engineering Services, PA to assist with developing and
implementing a sediment sampling program that would assist the Town in
meeting their requirements for this proposed undertaking. S&EC consulted and
coordinated with the Town, their consulting engineer, NCDENR, and the Corp
during the process of developing the sampling program, All parties had input
and approved the final sampling program proposed by S&EC. S&EC provided
the sampling program in a proposal form to Engineering Services, PA dated May
1, 2008. As best as S&EC could determine, based on the above referenced
consultation / coordination, there was no predetermined set of analytical
procedures for sediment sampling that applied to the particular work proposed
by the Town of Carolina Beach. There was of course the requirement to remove
and dispose of the sediment in such a manner that no adverse impacts occur to
human health or the environment.
S&EC was on site June 4, 2008 to collect the sediment samples from the lake. The
lake was divided up into two sections with the intent to collect one composite

sediment sample from each section. S&EC used a solid trap box device to
retrieve sediment from 3 - 4locations within each specified section of the lake.
The individual samples were then combined and a composite sample was made
up from the mix for each section of the lake. Those samples were immediately
placed in jars, stored in a cooler on ice until they could be transported to the lab
for analysis.
Each composite sample was analyzed for the presence of RCRA metals (EPA
Methods 7471 & 601013) and for semi -volatile organic compounds (EPA Method
8270) as per the previous consultation / coordination with all parties as
referenced above. Attachment 1 to this memo is a copy of the lab results for both
of the composite samples collected, As expected the sediment did contain
concentrations of several of the RCRA metals. S&EC reviewed those results and
did not find evidence of any gross contamination of RCRA metals in the samples.
Most of the metals tested for are naturally occurring in the soil and it is normal to
find some concentrations in any natural soil samples. The concentration of lead
and arsenic in the samples was higher than concentrations noted by S&EC in
other soil samples analyzed for various purposes and from various locations but
still within the range of naturally occurring levels. Concentrations of lead,
arsenic and other RCRA metals can vary widely from location to location and
among different soil types. There was no sampling of soils from "outside" the
lake in this case and therefore S&EC cannot comment as to how the metals
concentrations in the sediment compare to local "background levels." In any
event there is no evidence of gross contamination of metals in the sediment
samples.
There was only one compound defected in the semi-volatiles analysis, that being
a low level of bis-phthalate in Sample "Sed-1". S&EC compared the
concentration of that compound detected to maximum levels in NCDENR
standards and found that the level was well below the regulatory maximum for
that compound. No other semi-volatiles were detected in Sample Sed-1 and no
"hits" of any compound were found in Sample Sed-2.
S&EC recommends continued consultation and coordination with NCDENR and
the Corps as the Town moves forward with plans for cleaning out the lake.
S&EC will be glad to continue assistance in this effort as needed.
Water Table Assessment
S&EC performed shallow (4 to 6 ft) soil borings, one on the north side of the lake
and one on the south side of the lake, approximately 25 to 30 ft from the edge of
the lake. The soil boring locations were placed outside of pedestrian and
vehicular traffic. A sketch map is attached that shows the approximate locations
of the soil borings and temporary wells installed by S&EC. The purpose of the

soil borings was to describe the soil morphology and identify the seasonal high
water table. Soil profile descriptions are provided for each temporary well
location (see Attachment 2). Based on the review of the soil cutting, each location
had signs of disturbed soil or fill material placed on top of the old natural land
surface. Based on the profile description, an old buried "root matt" was noted at
32 inches below land surface. Also the soil morphology colors above the root
matt layer had signs of wetness conditions due to low chroma colors.
At the locations of the soil borings, S&EC installed a temporary water table
monitoring well using a 2 inch PVC well screen with clean sand and a bentonite
seal. These wells were developed until "clear water" was noted from each then
the wells were allowed to equilibrate for 24 hours. S&EC made measurements to
the depth of the apparent water table from each well on June 5 & 6, 2008.
Attachment 3 is a copy of the well information. As noted form the well data, the.
depth to the water table at TW-1 is 1.85 ft below land surface and at TW-2-it is
2.23 ft below land surface. After the water table depths were recorded, then each
temporary well was abandoned, and the borehole was sealed with hole plug.
The temporary wells were installed and abandoned under the supervision of a
certified well driller.
Soil & Environmental Consultants, PA is pleased to be of service in this matter
and we look forward to assisting in any site analysis needs you may have in the
future. Please feel free to call with any questions or comments.

Explanation of QC Qualifier Codes
Qualifier Meaning
J7 The associated batch QC was outside the established quality control range
for precision.
O (ESC) Sample diluted due to matrix interferences that impaired.the ability
to make an accurate analytical determination. The detection limit is
elevated in order to reflect the necessary dilution.
Jq The associated batch QC was outside the established quality control range
for accuracy.
Qualifier Report Information
ESC utilizes sample and result qualifiersasset forth by the EPA Contract Laboratory Program and
as required by most certifying- bodies including NELAC. In addition to the EPA qualifiers adopted
by ESCt. we have implemented ESC qualifiers to providemore information pertaining to our analytical
results. Each qualifier is designated inthe qualifier. explanation as either EPA or ESC.
Data qualifiers are intended to provide, the ESC client with more -detailed. informatics concerning
the potential bias of reported data. Because of the wide range of constituents and variety of
matrices incorporated. by most EPA methods, it is common for some compounds to fall outside of
established ranges.. These exceptions .are evaluated and all reported data is Valid and equable
unless qualified as ,R' (Rojected).
Definitions
Accuracy - The relationship of the observed value of a known sample to the
true value of a known sample. Represented by percent recovery and
relevant to samples such as: control samples, matrix 'pike recoveries,
surrogate recoveries, etc.
Precision - The agreement between a set of samples or between duplicate samples.
Relates to how close together the results are and is represented by
Relative Percent Differrence.
Surrogate - Organic compounds that are similar in chemical composition, extraction,
and chromotogrephy to analytea of interest. The surrogates are used to
determine the probable response of the group of analytas that are chem-
ically related to the surrogate compound. Surrogates are added to the
sample and carried through all stages of preparation and analyses.
TIC - Tentatively Identified Compound: Compounds detected in samples that are
not target compounds, internal standards, system monitoring compounds,
or surrogates.

The data package includes a summary of the analytic results of the quality
control samples required by the SW-846 or CWA methods. The quality control
samples include a method blank, a laboratory control sample, and the matrix
spike/matrix spike duplicate analysis. If a target parameter is outside
the method limits, every sample that is effected is flagged with the
appropriate qualifier in Appendix B of the analytic report.
Method Blank - an aliquot of reagent water carried through the
entire analytic process. The method blank results indicate if
any possible contamination exposure during the sample handling,
digestion or extraction process, and analysis. Concentrations of
target analytes above the reporting limit in the method blank are
qualified with the "B" qualifier.
Laboratory Control Sample - is a sample of known concentration
that is: carried through the diges Linn/extraction and analysis
process. The. percent recovery, expressed as a: percentage of the
theoretical concentration, has statistical control 'limits
.indicating that :.the analytic process In in control". If a
target analyte is 'outside the control limits for the. laboratory
control .sample or any .other. control sample, the parameter is
flagged with a "J4" qualifier for. all effected samples.
