RECEIVEDOCT1 5 '1993
These remarks are in addendum to comments previously coffered
August 31, 1993.
The Mooresville Regional Office groundwater staff conducted an
investigation of the: National Welders site. During their
investigation it was determined that groundwater was fairly deep,
greater than 20 feet, and that flog from the lime pond into the
groundwater was not occurring in significant quantities. This is
apparently the result of the lime sealing the soils below the pond.
Groundwater flow may be traveling above this sealed layer and
therefore manifesting itself in the nearly creek.
The Groundwater Section doses not believe the new seepage
collection pond would result in an increased threat to groundwater
quality, As long as the collection: pond will be used for
reclamation purposes we do not object to the project,. However if
the collection pond will be used can a continual basis, then the
rules for liner requirements should apply.
If there are any questions, please let me know.

Groundwater Seepage and Stormwater Collection and

NPDES Permit No. NCO0079758
Mecklenburg County
I have reviewed the subject permit application for what
appears to be a lagoon designed to collect groundwater seepage and
stormwate r that is generated in the vicinity of an old unlined lime
storage pond. The new collection lagoon will also be used to store
collected groundwater seepage and stormwater for use in reslurrying
the lime in the lime pond for removal off-5ite. The need for
intercepting stormwater and groundwater seepage is apparently the
result of high pH groundwater and st-oar mwater adversely affecting
the down gradient receiving stream.

Subject: National welders Supply Company
Groundwater Seepage and Stormwater Collection and
Treatment Lagoon
DES Permit No.
Mecklenburg County
The subject proposal, as it relates primarily to groundwater
,seepage collection, does not address how groundwater will flow into
the collection lagoon. The applicant simply states that
groundwater flow will move into the collection lagoon without
providing any evidence to support; his theory» No evidence of
groundwater r depth, hydraulic gradient, sail information, litholo y,
velocity, or flow direction is given in the application documents.
With my general knowledge of Mecklenburg County, I believe that
water will move from the collection lagoon n into the groundwater.
The applicant must demonstrate through soils information and
hydrogeologic l information that water will flow into the
collection lagoon.
it is my understanding that the Mooresville Regional office
water quality staff wishes to have a liner in the lagoon. This may
be due to the fact that National Welders intends to continuously
use the collection lagoon for lime res .urryinc purposes;. If the
results of the hydroge logical investigation determine that
groundwater will flog into the collection lagoon throughout the
ear, then the Groundwater Section could agree that a liner would
be unnecessary: otherwise, a liner would be required for the
collection lagoon and an, alternative for groundwater collection
would need to be considered. Also, the fact that a house and water
supply wells are less that 400 feet from the collection lagoon and
lime ponds would further substantiate the need for a liner.
If theeare any questions, v an additional r if you

Section to e y n, please let me krnow

INTRODUCTION
n December 31, 1991, National Welders Supply Company (National
Welders) received a corrospondence from Ms. Barbara Christian of
the North Carolina Department of Environment Health and Natural
Resources requesting the groundwater in the vicinity of the lien
storage pond be assessed. As a result of this corrospondence,
National Welders retained AWARE Environmental Inc. (AEI) to
develop and implement an assessment program consisting of two
shallow groundwater monitoring well, one 1 installed up
gradient and one 1) immediately downradint the lime storage
pond.. These two wells were sampled and analyzed for pH,
magnesium and calcium:
The following sections of this report describe the procedures
utilized in implementing this assessment, and the analytical
results of these groundwater samples.

SECTION 2.0
SITE ASSESSMENT ACTIVITIES
In accordance with. December 13, 1992 proposal, on February 1.1
1. , 1992, AEI conducted a preliminary assessment of the
groundwater quality at the National Welders facility at 5301 Old
Dowd Road in Charlotte, forth Carolina.
To address the concerns related to possible seepage from the lime
storage pond, two shallowgroundwater monitoring wells were
permitted, constructed and sampled. one - these wells was
located upgradient and one 1 was, constructed immediately
downgradient of the lime storage pond. The results of these
assessment activities are presented below.
'ell Construction Permit
n January 31, 1992, prior to beginning monitoring well
construction, AEI submitted are application for a permit t
construct two shallow groundwater monitoring wells at the
National Welders facility at 5301 Old Dowd load, Charlotte, North
Carolina. AEI received authorization to proceed from the North
Carolina Department of Environment, Health `& Natural Resources,
Division of Environmental ;management Rid on February 10, 1992.
Well Construction Permit No. 5®11- was issued on
February 12, 1992.

Monitorinct Well Construction
In order to assess potential impacts the lase storage ponds may
have had on the local groundwater quality, two ( shallow
groundwater monitoring wells were constructed, one upgradient of
the lime storage pond and one (1) downgradient of the lame
storage pond seeFigure 1:
The borings were advanced utilizing continuous flight hollow stem
auger techniques in accordance with ASTM 1 8 . Soil samples
were collected on five ( fact intervals using a split -spoon
sampler .in accordance with A^S D 1586-84. Each sample was
visually ;described in eneral accordance with the Unified Soil
classification System (U and the Munsell Soil Color chart,
1988 edition. The background and well ( - was terminated at a
depth of feet below grade. The down gradient well -a
encountered wager refusal at 16 feet below' grade. Each well was
completed with -inch diameter schedule 40 PVC casing and
manufactured screen in accordance Frith the North Caroling
Administrative Code ( A , Title 15, Subchapter 2C, Well
Construction Standards. All soil generated during well
construction activities were containerized in DOT approved
gallon steel drums and left on -site for approved disposal by
National Welders. complete boring lags and Well Construction

In order to minimize the potential for cross contamination
between bore holes, all downhele drilling equipment was steam
cleaned prier to advancing each hole and prior to .eav g the
site. In addition, the split -spoon sampler was thoroughly gashed
with phosphate free detergent,, rinsed with tap water and there
rinsed with distilled water prier to collectingeach sample. All
decontamination water was collected and contained in labeled DOT
approved 55-gallon steel drums and left on site for approved
disposal by National Welders.
Groundwater Samnlina and Analvsis
Groundwater samples were collected from both monitoring wells -
i and 1 on February 14, 1992. All samples were collected in
general accordance with :SPA. sampling protocol as described below.
Prior to purging either well, the static water level in each well
was measured from the top of the well casing to the nearest 0.01
foot. The water levels were regarded in a field loth bete and
used to calculate the volume of water standing .in each well.
Dedicated Teflon bailers prepared by Industrial and Environmental
Analysts,- Inc. ) were used for the devel ping Purg inn and
sampling of wells., New rubber gloves were Oren during the
developing/purging and sampling of each well to avoid cross -
contamination between the wells. All wells were developed/purged
of at least three ) times the calculated volume of water in the
5

given well or until dry, whichever occurred first, prior to
collecting groundwater samples. Well purge water was
containerized in labeled 55-gallon drums with the rinse water and
left on site for approved disposal by National Welders.
Samples were collected from each well in EPA approved containers
provided by the analytical laboratory. Each container was
labeled specifying the date, well number, constituents to be
tested for, the time the samples were collected, and the samplers
initials. Each sample was logged on a Chain -Of -Custody form, and
placed on ice immediately after collection, in preparation for
transport via overnight courier to the analytical laboratory. In
addition, a small sample of groundwater was placed in a clean
beaker for temperature and pH measurement at the time of sample
collection, see Table 1.
The samples collected were analyzed for total magnesium and
calcium in accordance with Inductively Coupled Plasma, SW-846 3rd
Addition, Method 6010J. Revision I. The pH was analyzed in
accordance with EPA Method 150.1. The results of the analyses
are presented in Table 1.
