Preface
Ground water is one of North Carolina's
most valuable natural resources. It is the
primary source-of water supplies in rural areas
and is also widely used by industries and
municipalities, especially in the Coastal Plain.
However, its use is not increasing in proportion
to the growth of the State's population and
economy. Instead, the present emphasis in
water-supply development is on large regional
systems based on reservoirs on large streams.
The value of ground water as a resource not
only depends on its widespread occurrence
but also on its generally excellent chemical
quality. Thus, in most cases, ground-water
does not require treatment prior to use, except
as a precaution against unsuspected pollution.
However, in an effort to control stream
pollution, greater and greater emphasis is
being placed on the land disposal of liquid and
solid wastes. One result of this may be
increasingly widespread deterioration of
ground-water quality.
The development of ground-water supplies
and the protection of ground-water quality
requires knowledge of the occurrence of
ground water and knowledge of how ground-
water systems function. The lack of such
knowledge among those involved in the
development, management, and regulation of
water supplies has been an important element
in the avoidance of ground water as a source of
large supplies and in the increasing occur-
rence of ground-water pollution.
This report was prepared as an aid to
developing a better understanding of the
ground-water resources of the State. It
consists of 46 essays grouped into five parts.
The topics covered by these essays range from
the most basic aspects of ground-water
hydrology to the identification and correction
of problems that affect the operation of supply
wells. The essays were designed both for self
study and for use in workshops on ground-
water hydrology and on the development and
operation of ground-water supplies.
Relative to the use of this report in
workshops, selected essays have been used in
workshops for the staff of the North Carolina
Department of Natural Resources and Com-
munity Development and in short courses for
operators of water systems that utilize wells as
a source of supply. The essays used in each
workshop and short course were selected on
the basis of the background and needs of the
group.
Finally, most of the essays contain sketches
that illustrate the main points covered in the
text. However, to facilitate the rearrangement
of essays for use in different workshops, they
are not numbered and titled as in most
technical reports. For those who find this
disconcerting, I suggest that the text of each
essay simply be viewed as an expanded
explanation of the sketches.

In 1975, North Carolina had 224 municipal
water systems serving 500 or more customers.
Of these systems, 102 obtained a part or all of
their water from wells. These systems serve
more than 500,000 people with 70 Mgal/day
(million gallons per day) of water. These
figures show the importance of ground water in
North Carolina as a source of municipal
supplies. They do not, however, show the
overall importance of ground water.
In addition to the people served ground
water through municipal systems, more than
2,400,000 people living in rural areas (of a total
State population of more than 5,000,000)
obtain their water supplies from wells and
springs. Ground water is also an important
source of water for industries and agriculture.
The U.S. Geological Survey estimates that
540 Mgal/day of ground water were being used
in North Carolina in 1975. Most of this use is in
the Coastal Plain region where ground water is
obtained from extensive and productive sand
and or limestone aquifers. Although the
aquifers underlying the Piedmont and moun-
tains are much less productive than those in
the Coastal Plain, ground water is an important
source of supply for small cities and industries
and is the primary source for rural homes and
farms.

Most of the rocks near the Earth's surface are
composed of both solids and holes. The solid
part is, of course, much more obvious than the
holes, but without the holes there would be no
underground water to supply wells and
springs.
There are different kinds of holes in rocks
and it is sometimes useful to be aware of these.
If the holes were formed at the same time as the
rock, they are referred to as primary openings.
The pores in sand and gravel are primary
openings. The sand aquifers underlying the
Coastal Plain contain water in primary
openings.
If the holes were formed after the rock was
formed, they are referred to as secondary
openings. The fractures in granite and other
igneous and metamorphic rocks are secondary
openings. Caverns in limestone, which are
formed as ground water slowly dissolves the
rock, are an especially important type of
secondary opening. Ground water in the
bedrock underlying the Piedmont and moun-
tains occurs in secondary openings, as
does much of that in the limestones underlying
the Coastal Plain.

GROUND WATER
All water beneath the land surface is referred
to as underground water. The equivalent term
for water on the land surface is surface water.
Underground water occurs in two different
zones. One zone, which occurs immediately
below the land surface in most areas, contains
both water and air and is referred to as the
unsaturated zone. The unsaturated zone is
almost invariably underlain by a zone in which
all interconnected openings are full of water.
This zone is referred to as the saturated zone.
Water in the saturated zone is the only
underground water that is available to supply
wells and springs and is the only water to which
the name ground water is correctly applied.
Recharge of the saturated zone occurs by
percolation of water from the land surface
through the unsaturated zone. The unsatura-
ted zone is, therefore, of great importance to
ground-water hydrology. This zone may be
divided usefully into three parts (or subzones);
(1) the soil zone, (2) the intermediate zone, and
(3) the capillary fringe.
The upper part - from the land surface to a
depth of several feet - is referred to as the so/7
zone. The soil zone is the zone that supports
plant growth. It is crisscrossed by living roots,
by holes left by decayed roots of earlier
vegetation, and by animal and worm burrows.
This zone tends to have a higher porosity and
to be more permeable than the underlying
material. The soil zone is underlain by the
intermediate zone, which differs in thickness
from place to place depending on the thickness
of the soil zone and the depth to the capillary
fringe.
Moving to the lowest part of the unsaturated
zone, the boundary between it and the
saturated zone is occupied by the capillary
fringe. The capillary fringe results from the
attraction between water and rocks. As a result
of this attraction, water clings as a film on the
surface of rock particles and rises up small-
diameter pores against the pull of gravity.
Water in the capillary fringe and in the
overlying part of the unsaturated zone is
under a negative hydraulic pressure - that is, it
is under a pressure less than atmospheric. The
water table is the level in the saturated zone at
which the hydraulic pressure is equal to
atmospheric pressure.
Hydrologic Cycle
The term hydrologic cycle is used to refer to
the constant movement of water above, on, and
below the Earth's surface. The concept of the
hydrologic cycle is central to an understanding
of the occurrence of water and the develop-
ment and management of water supplies.
Although the hydrologic cycle has neither a
beginning nor an end, it is convenient to
discuss its principal features by starting with
evaporation from vegetation, from exposed
surfaces including the land surface, and from
the ocean. This moisture forms clouds which,
under favorable conditions, return the water to
the land surface or oceans in the form of
precipitation.
Precipitation occurs in several forms,
including rain, snow, and hail, but we will
consider only rain in this discussion. The first
rain wets vegetation and other surfaces and
then begins to infiltrate into the ground.
Infiltration rates vary widely, depending on
land use, from possibly as much as an inch per
hour in mature forests to a tenth of an inch per
hour in silty soils under cultivation. When and if
the rate of precipitation exceeds the rate of
infiltration, overland flow occurs.
The first infiltration replaces soil moisture
and thereafter the excess percolates slowly
across the intermediate zone to the zone of
saturation. The water in the zone of saturation
moves downward and laterally to sites of
ground-water discharge such as springs on
hillsides or seeps in the bottoms of streams and
lakes or beneath the ocean.
Water reaching streams, both by overland
flow and from ground-water discharge, moves
to the sea where it is again evaporated to
perpetuate the cycle. •
Movement is, of course, the key element in
the concept of the hydrologic cycle. Some
"typical" rates of movement are shown in the
following table, along with the distribution of
the Earth's water supply.

From the standpoint of ground-water
occurrence, all rocks underlying the Earth's
surface are classified either as aquifers or
confining beds. An aquifer is a rock unit that
will yield water in a usable quantity to a well or
spring. (In geological usage, "rock" includes
unconsolidated sediments.)
A confining bed is a rock unit that restricts
the movement of ground water either into or
out of adjacent aquifers.
Ground water occurs in aquifers under two
different conditions. Where water only partly
fills an aquifer, the upper surface of the
saturated zone is free to rise and decline. The
water in such aquifers is said to be unconfined
and the aquifers are referred to as unconfined
aquifers.
Where water completely fills an aquifer that
is overlain by a confining bed, the water in the
aquifer is said to be confined. Such aquifers are
referred to as confined aquifers.
Wells open to unconfined aquifers are
referred to as water-table wells. The water level
in these wells indicates the position of the
water table in the surrounding aquifer.
Wells drilled into .confined aquifers are
referred to as artesian wells. The water level in
artesian wells stands at some height above
the top of the aquifer but not necessarily above
the land surface.
The static water level in tightly cased wells
open to a confined aquifer stands at the level of
the potentiometric surface of the aquifer.

If we multiply the porosity determined with
equation 1 by 100, the result is porosity expres-
sed as a percent.
Soils are among the most porous of natural
materials because soil particles tend to form
loose clumps and because of the presence of
root holes and animal burrows.

Porosity is important in ground-water hy-
drology because it tells us the maximum
amount of water a rock can contain when it is
saturated. However, it is equally important to
know that only a part of this water is available
to supply a well or a spring.
Hydro legists divide porosity into the part
that will drain under the influence of gravity
(called specific yield) and the part that is re-
tained as a film on rock surfaces and in very-
small openings (called specific retention). It
should be noted that the physical forces that
control specific retention are the same forces

In many ground-water investigations it is
either necessary or desirable to know the depth
to the water table and the direction and rate
of ground-water movement. Both of these
require the measurement of the position of the
water level in wells.
The first step is to identify (and describe) a
fixed point - measuring point (MP) - that all
measurements will be referred to. The depth
to the water level below the measuring point
can be measured by any of several means.
(See MEASUREMENTS OF WATER LEVELS
AND PUMPING RATES.) In order to deter-
mine the direction and rate of ground-water
movement, it is necessary to measure the
depth to water (D to W) in at least three wells
and to determine the altitude of their measur-
ing points with respect to a common datum
plane - usually mean sea level (now officially
the National Geodetic Vertical Datum of 1929).
If the D to W in a nonflowing well is sub-
tracted from the altitude of the MP, the result is
the total head at the well. Total head, as we
know from fluid mechanics, is composed of
elevation head, pressure head, and velocity
head. Because ground water moves relatively
slowly, we can ignore velocity head. There-
fore, the total head at an observation well
involves only two components - elevation head
and pressure head. Ground water moves in the
direction of decreasing total head; this may
or may not be in the direction of decreasing
pressure head.
The equation for total head (hs) is
(I)
where z is elevation head and is the distance
from the datum plane to the point where the
pressure head is hp.
All other factors being constant, the rate of
ground-water movement depends on the hy-
draulic gradient. The hydraulic gradient is the
change in head per unit of distance in a given
direction. If not specified, the direction is
understood to be in the direction in which the
maximum rate of decrease in head occurs.
10
If we assume that the movement of ground
water is in the plane of the preceding draw-
ing - in other words, that it moves from well
1 to well 2 - we can calculate the hydraulic
gradient from the information given on the
drawing. The hydraulic gradient is hL/L where
h|_ is the head loss between wells 1 and 2 and L
is the distance between them, or
h L (100 ft -15 ft) - (98ft-18ft)
L " 780ft
85 ft - 80 ft _ 5ft
780 ft 780 ft
Gradients are usually expressed in feet/mile
or feetper 1000 eetThus
Both the direction of ground-water move-
ment and the hydraulic gradient can be deter-
mined if the following data are available for
three wells located in any triangular arrange-
ment such as that shown on Sketch A.
1. The relative geographic position of the
wells,
2. The distance between the wells, and
3. The relative position of the water level in
each well.
Steps in the solution are outlined below
and illustrated on Sketch B.
(a) Identify the well that has the inter-
mediate water level-that is, neither
the highest nor the lowest water level.
(b) Calculate the position between the
wells having the highest and lowest
water levels at which the ground-
water level is the same as in the
intermediate well.
(c) Draw a straight line between the
intermediate well and the point
identified in step b between the wells
having the highest and lowest water
level. This line represents a segment
of the water-level contour along
which the total head is the same as in
the intermediate well.
(d) Draw a line perpendicular to the
water-level contour and through
either the well with the highest or the
lowest water level. This line parallels
the direction of ground-water move-
ment.
(e) Divide the difference in water level
between the well and the contour by
the distance between the well and
the contour. The answer is the
hydraulic gradient.

Unit prism of aquifer
Aquifers transmit water from recharge areas
to discharge areas and thus function as pipe-
lines. The factors controlling ground-water
movement were first expressed in the form of
an equation by Henry Darcy in 1856. Darcy's
law is
where
dl
Q is the quantity of water,
K is hydraulic conductivity and
depends on the size and
arrangement of the water-
transmitting openings (pores
and fractures),
A is cross-sectional area through
which the flow occurs, and
dh/dl is the hydraulic gradient.1
Because the quantity of water (Q) is directly
proportional to the hydraulic gradient (dh/dl),
we know that ground-water flow is laminar -
that is, water particles tend to follow discrete
streamlines and not mix with particles in adja-
cent streamlines.
Hydraulic conductivity is expressed in terms
of a unit hydraulic gradient (such as foot per
foot) in order to permit ready comparison of
the water-transmitting capacity of different
materials.
The units of hydraulic conductivity are those
of velocity. Thus, if we rearrange equation 1 for
K, we obtain
Adh

(ft2) (ft)(2)

Hydraulic conductivity replaces the term "field coefficient of permeability" and should be used when
referring to the water-transmitting characteristic of material in quantitative terms. It is still permissible
to refer in qualitative terms to "permeable" and "impermeable" material.

Functions of
Ground-Water Systems
Discharge
area
GROUND-WATER SYSTEM
The aquifers and confining beds underlying
any area comprise the ground-water system of
the area. Hydraulically, this system serves two
functions: (1) it stores water to the extent of its
porosity, and (2) it transmits water from re-
charge areas to discharge areas. Thus, a
ground-water system serves both as a reservoir
and as a pipeline. With the exception of
cavernous limestones and lava flows, ground-
water systems are more effective as reservoirs
than as pipelines.
Water enters ground-water systems in
recharge areas and moves through them, as
dictated by hydraulic gradients and hydraulic
conductivities, to discharge areas.
The identification of recharge areas is
becoming increasingly important because of
the expanding use of the land surface for waste
disposal. In a humid area, such as North Caro-
lina, recharge occurs in all interstream areas -
that is, in all areas except along streams and
their adjoining flood plains. The streams and
flood plains are, under most conditions,
discharge areas.
Recharge rates are generally expressed in
terms of volume (such as gallons or ft3), per
unit of time (such as a day or a year), and per
unit of area (such as a square mile or acre).
When the units are reduced to their simpliest
form, the result is recharge expressed as a
depth of water on the land surface per unit of
time. Recharge rates vary from year to year,
depending on the amount of precipitation, its
seasonal distribution, air temperature, and
other factors. Among the other factors are land
use. For example, recharge rates are much
higher in forest than in cities.
14
Relatively few estimates of recharge rates
have been made in North Carolina. The
information presently available suggests that
rates in the Piedmont and mountains range
from about 100,000 gallons per day per square
mile in the areas underlain by Triassic rocks to
about 250,000 (gal/d)/mi2 in areas underlain by
granite and gneiss. Rates in the Coastal Plain
are believed to range from about 250,000
(gal/d)/mi2 in areas underlain by clayey soils to
1,000,000 (gal/d)/mi2 in areas underlain by
thick sandy soils.
The rate of movement of ground water from
recharge areas to discharge areas depends on
the hydraulic conductivities of the aquifers and
confining beds through which the water moves
and on the hydraulic gradients. (See GROUND-
WATER VELOCITY.) A convenient way of
showing the rate is in terms of the time required
for ground water to move from different parts
of a recharge area to the nearest discharge
area. The time ranges from a few days in the
zone adjacent to the discharge area to
thousands of years (millennia) for water that
moves from the central part of the recharge
area through the deeper parts of the system.
Natural discharge from ground-water
systems not only includes the flow of springs
and the seepage of water into stream channels,
but also evaporation from the upper part of the
capillary fringe where it occurs within a few
feet of the land surface. Large amounts of
water are also withdrawn from the capillary
fringe and zone of saturation by plants during
the growing season. Thus, discharge areas not
only include the channels of perennial streams
but also the adjoining flood plains and other
low-lying areas.
One of the most significant differences
between recharge areas and discharge areas is
that discharge areas are invariably much
smaller in areal extent that recharge areas. This
shows, as we would expect, that discharge
areas are more "efficient" than recharge areas.
Recharge involves unsaturated movement of
water in the vertical direction; in other words, in
the direction in which the hydraulic conductiv-
ity is generally the lowest, whereas discharge
involves saturated movement, much of it in the
horizontal direction - that is, in the direction of
the largest hydraulic conductivity.

PART II.
GROUND-WATER GEOLOGY
OF NORTH CAROLINA
"It is time that we return to examining
hydrologic systems and attempting to
describe the systems in a more realistic,
quantitative manner. When one comes to
solving problems of chemical contamina-
tion, it is necessary to quantify the
distribution of porosity, dispersivity, and
other factors. Dispersivity measured at only
a few field locations tends to be large; from
three to more than five orders of magnitude
larger than those measured in the labora-
tory. This suggests that the geologic
complexity of real aquifers greatly compli-
cates the flow field, causing increased
hydrodynamic dispersion.
-From remarks by Dr. John Bredehoeft at hearings on
"Ground-water quality research and development"

Atmosphere, 95th Congress, 2nd Session, April

From the standpoint of ground-water
hydrology, North Carolina may be divided into
two zones, one zone consisting of the Coastal
Plain and the other consisting of the Piedmont
Plateau and the Appalachian Mountains.
Because differences in the ground-water
system coincide with the different topographic
divisions of the State, it will be useful to briefly
review these divisions.
As Jasper L. Stuckey, former North Carolina
State Geologist, has said, "The State of North
Carolina extends from the crest of the Great
Smoky and Unaka mountains on the west, to
the Atlantic Ocean on the east and lies across
three major topographic provinces of the
United States. As a result, it is divided into three
natural divisions—the Coastal Plain on the
east, the Piedmont Plateau in the center, and
the Appalachian Mountains on the west.
Beginning at sea level at the eastern edge of the
State the surface of North Carolina rises
gradually in elevation and increases in
irregularity until it reaches its maximum height
and ruggedness in the Appalachian Mountains
on the west."
The Coastal Plain includes almost one-half
of the area of the State and extends west from
the Atlantic Ocean to the Fall Line. The Fall
Line is not a line but a zone 30 to 40 miles wide
that is marked by discontinuous rapids where
major streams leave the bedrock areas of the
Piedmont and flow onto the unconsolidated
sediments of the Coastal Plain. Altitudes in the
Coastal Plain range from sea level at the coast
to about 300 to 500 ft. along the Fall Line. The
Coastal Plain can conveniently be divided into
the Tidewater Region, in which the effect of
tides and other oceanic influences are
apparent, and the Inner Coastal Plain which,
though underlain by unconsolidated (Coastal
Plain) sediments, is not subject to direct
oceanic effect.
The Piedmont Plateau contains about
20,000 mi2, or two-fifths of the land area of the
State. It lies between the Coastal Plain on the
east and the Appalachian Mountains on the
west. Altitudes in the Piedmont range from
about 500 ft above sea level along the Fall Line
to about 1500 to 2000 ft. along its western
border. The Piedmont consists of well-
rounded hills and long-rolling ridges with a
northeast-southwest trend. Parts of the
Piedmont contain prominent hills referred to as
mountains, including the Uwharrie Mountains
in Montgomery and Randolph Counties, the
South Mountains in Burke and Rutherford
Counties, and the Brushy Mountains in Wilkes
County.
The Appalachian Mountains are bounded on
the east by the Blue Ridge Mountains and on
the west by the Great Smoky and Unaka
Mountains. The mountain slopes are gentle,
presenting smooth rounded outlines. The
mountain region of North Carolina contains
the highest peak east of the Mississippi, Mt.
Mitchell at 6,684 ft., 43 peaks above 6,000 ft,
and 82 peaks between 5,000 and 6,000 ft. in
altitude. The eastern Continental Divide
follows the Blue Ridge Mountains so that most
of the mountain area drains west to the Gulf of
Mexico. The streams are well graded and
cascades and waterfalls are only locally
abundant.

Water-Bearing Rocks
The rocks underlying the surface of North
Carolina form the environment in which
ground water occurs and moves.
Geologists divide all rocks exposed at the
Earth's surface into one of two great classes:
(1) igneous, or (2) sedimentary. Igneous rocks
are those that have formed from a molten or
partially-molten state. Some types of igneous
rocks, including granite, solidify at great depth
below the land surface and are referred to as
intrusive igneous rocks. Other igneous rocks
form from lava or volcanic ash ejected onto the
surface and are referred to as extrusive
igneous rocks.
Sedimentary rocks are rocks formed by the
accumulation of sediment in water or from the
air. Most sedimentary rocks are unconsolida-
ted (soil-like) at the time of formation. If they
are, in time, buried deeply enough, or if they
undergo certain chemical changes, they may
become consolidated.
Both igneous and sedimentary rocks may,
over the course of geologic time, reach depths
beneath the Earth's crust at which they are
subjected to great heat and pressure. This may
alter both their structural characteristics and
their mineral composition to such an extent
that they are changed into metamorphic rocks.
Depending on their original mode of origin,
they may be referred to, for example, as
metavolcanic or metasedimentary rocks.
North Carolina is underlain by an unusually
large number of different types of rocks,
including representatives of both the igneous
and sedimentary classes and types of both
classes that have been subjected to metamor-
phism. The major types of rocks are shown on
the accompanying generalized geological
map.
The Piedmont and mountain regions are
underlain by igneous and metamorphosed
igneous and sedimentary rocks that are
referred to collectively as bedrock. They form
broad northeast - southwest trending zones in
which the rocks are of similar composition and
origin. Most of these rocks were formed in the
Precambrian and Paleozoic Erasof the Earth's
history and thus are at least several hundred
million years old. The bedrock in the Piedmont
and mountains is exposed at the surface along
steep hillsides and stream channels and in
roadcuts. In most other areas they are covered
by unconsolidated material formed from the
breakdown of the bedrock in the process refer-
red to by geologists as weathering. This layer
of weathered material is referred to as saprolite
or residuum.
The Coastal Plain region is also underlain by
the same types of igneous and methamorphic
rocks as those present in the Piedmont.
However, in the Coastal Plain they are covered
by unconcolidated sedimentary deposits
which range in thickness from a few feet along
the Fall Line to about 10,000 ft. at Cape
Hatteras. (See the geologic section in
PHYSICAL SETTING OF THE GROUND-
WATER SYSTEM.) The sediments underlying
the Coastal Plain include sand, clay, beds
composed of seashells, and limestone.

Subject: Final Removal Assessment Letter Report
Chapel Street Battery Dump
Kannapolis, Rowan County, North Carolina
EPA Contract No. EP-W-05-054
TDD No. TTEMI-05-003-0082
Dear Ms. Sholar and Mr. Crowley:
The Tetra Tech EM Inc. (Tetra Tech) Superfiind Technical Assessment and Response Team (START) is
submitting the final removal assessment (RA) letter report for the Chapel Street Battery Dump (CSB) site
located in Kannapolis, Rowan County, North Carolina. This report includes figures (Appendix A), tables
(Appendix B), a photographic log (Appendix C), field logbook notes (Appendix D), and residential well
field sample collection sheets (Appendix E). The analytical data package is included in Attachment 1.
This letter report summarizes field activities conducted on the property during the RA at the CSB site on
March 30 and 31, 2010. The general purposes ofthe RA were to (1) determine the presence or absence of
lead in residential drinking supplies, (2) identify whether concentrations of lead are above the U.S.
Environmental Protection Agency (EPA) maximum contaminant levels (MCL) for lead in drinking water
supplies, and (3) characterize the surface soil on residential properties by (a) performing x-ray
fluorescence (XRF) screening, (b) collecting confirmation soil samples for laboratory analysis (at
locations indicated by XRF analysis), and (c) comparing laboratory analytical results to the EPA Region 4
removal action levels (RAL) for lead and arsenic in surface soil.
SITE BACKGROUND
The CSB site is located in Kannapolis, Rowan County, North Carolina, in a predominantly residential
area (see Figure 1 in Appendix A). The geographic coordinates for the CSB site are latitude 35° 31' 53"
north and longitude 80° 36' 44" west. The site is comprised of about 20 parcels of land that encompass a
footprint of approximately 15 acres. The site is bound to the north by East (E) 31^* Street followed by a
residential property, to the east by Chapel Street followed by a coimnercial property, to the south by E

29* Street followed by a residential property, and to the west by Kirk Avenue followed by railroad tracks
and residential properties.
According to informafion provided by the North Carolina Department of Environment and Natural
Resources (NCDENR), Inactive Hazardous Sites Branch (IHSB), the site is located along an unpaved U-
shaped road named Psalms Street, between E 3 T* Street and E 29*^ Street in Kannapolis, NC. This road is
in the vicinity ofthe Victor Melton Construction Company (VMC), at the former location of B&W
Grocery (exact location not provided). Broken battery casings and chips were reportedly dumped at the
rear of the fonner store property. The source of the battery casings/chips was suspected to be the Hartsoe
Brothers Battery Dump site (NCD108702606), which is located at 2513 Linda Ave. in Kannapolis, NC.
This location is not within the CSB site study area specified above.
The IHSB conducted site reconnaissance activities at the site on two occasions. In December 1998, the
owner ofthe property at 1102 Chapel Street clarified for the IHSB that the battery chips in question were
not located on the VMC property, but on the residential property adjacent to VMC. However, at that
time, Ms. Harriet Melton, who owns the residential property told the IHSB that no battery chips had been
found on her property during grading operations that were being conducted at that time.
In August 2000, the IHSB conducted another site visit at the CSB site. IHSB did not report finding
battery casings or chips on the VMC property, but did observe three areas along Psalms Street with
battery casings and chips at the surface ofthe property. According to the IHSB, each ofthe three areas
was about 6 feet wide by about 10 feet long. These areas were designated as Psalms Street A, B, and C
by the IHSB. The IHSB did not collect any subsurface soil samples at the time to determine whether
chips were present at depths below the surface or to assess possible lead concentrations in the soil. The
property within the "U" of Psalms Street is owned by Ms. Margaret Caldwell. During a site visit by the
IHSB in 2000, potable water supply wells were observed within 300 to 500 feet east and north ofthe site.
According to Mr. Melton, the depths of these wells are unknown. Samples collected from the wells did
not contain hazardous substances above the detection limits. In April 2009, IHSB conducted soil
sampling at the CSB site with a bias toward areas with visible battery chips. Analytical results for the soil
samples collected indicated lead concentrations up to 43,600 milligrams per kilogram (mg/kg).

ASSESSMENT ACTIVITIES
On January 19, 2010, EPA OSC Ken Rhame and Tetra Tech START conducted a reconnaissance ofthe
CSB site to visually assess areas along Psalms Street for the presence of battery chips, and to request
authorization from owners/occupants of properties within the site to conduct the sampling phase ofthe
removal assessment. On March 30, 2010, Tetra Tech START met EPA OSC Lynnette Sholar at the CSB
site. OSC Sholar and Tetra Tech START personnel held a tailgate health and safety site briefing to
establish hospital routes, site hazards, and setup communication protocols prior to initiating site activities.
OSC Sholar and Tetra Tech START personnel performed a walkthrough ofthe CSB site to identify
property parcel boundaries, key site features, and areas where battery chips had been discovered during
the initial site reconnaissance conducted by the IHSB. During the RA, Tetra Tech START (1) screened
the surface soil for the presence of lead and arsenic using a Niton XRF spectrometer, and (2) collected 28
composite surface soil samples, 18 grab surface soil samples, and five residential potable well samples for
laboratory analysis for lead and arsenic. For the purposes ofthis RA, the properties in that comprise the
CSB site were given unique site-specific property parcel numbers CSBOOl through CSB020.
SURFACE SOIL SCREENING AND SAMPLING
During the RA, Tetra Tech START collected 28 five-point composite surface soil samples from 20
parcels that encompassed the site. For proper characterization ofthe site, three parcels (CSBOOl,
CSBOl 1, and CSB016) were split into sub-sections because ofthe large sizes of these parcels. Parcel
CSBOOl was split into four sub-sections, parcel CSBOl 1 was split into two sub-sections, and parcel
CSB016 was split into three sub-sections. The 17 remaining parcels were sampled as one composite
sample per parcel. Two duplicate composite surface soil samples were collected, one each from
properties CSB005 and CSB016. The five-point composite surface soil samples were collected from a.
depth between 0 to 6 inches below ground surface (bgs) rather than between 0 to 12 inches bgs,
considering the visual identification of battery chips at the surface level. Tetra Tech START collected
five individual aliquots of surface soil from the fi^ont, side, and rear areas surrounding the residential or
commercial building structure on each property parcel. The individual aliquots were collected using
stainless steel spoons and augers, placed into disposable aluminum pans, and homogenized prior to

Teclmical Procedure (FBQSTP) Standard Operating Procedure (SOP) for soil sampling, SESDPROC-
300-Rl.
Also during the RA, Tetra Tech START collected 18 grab surface soil samples from various areas along
Psalms Street. Psalms Street mostly is made up of gravel, soil, and battery chips. Samples were collected
at intervals of about 50 feet, altemating locations on both sides ofthe street. Each grab sample was also
collected from a depth of 0 to 6 inches bgs due to visual identification of battery chips along the roadway
surface. Grab samples were collected using stainless steel spoons and augers, placed into disposable
aluminum pans, and homogenized prior to screening and sampling activities.
Prior to placement ofthe soil samples into the appropriate sample container for laboratory analysis, a
Niton XRF spectrometer was used to screen the soil samples for lead contamination (see Tables 1 and 2 in
Appendix B). XRF screening was conducted in the aluminum pans after the soil was homogenized. Ten
ofthe samples screened indicated lead contamination at concentrations ranging from 461 to 4,794 mg/kg
—above the RAL of 400 mg/kg for lead. Tetra Tech START personnel conducted XRF screening in
accordance with the EPA Region 4SESD, FBQSTP SOP for X-ray Fluorescence Measurement,
SESDPROC-107-Rl. Prior to use, the XRF spectrometer was subjected to a calibration procedure
ensuring that the instrument's readings were within the acceptable range of accuracy.
POTABLE WELL SAMPLING
Tetra Tech START collected five potable water samples from residential wells. Tetra Tech START and
OSC Sholar communicated with the property owners and inspected each property to determine the
location at which the potable well sample would be collected. All residential potable water well samples
were collected from a spigot at the well head or a spigot outside ofthe residence. Prior to sampling
activities, water quality parameters were monitored using an YSI-85, Horiba, pH meter, and a Lamotte
turbidity meter. All instruments were calibrated using manufacturer-provided calibration solutions and
methods prior to use in the field. The instruments also were calibrated following sampling at each
residential potable water well location. Water from each well was allowed to run for approximately 15 to
20 minutes to purge the well of standing water. Once purging was completed, water quality
measurements ensued for parameters including pH, conductivity, temperature, and turbidity.
Measurements for pH, conductivity, and temperature were within 10 percent, and turbidity measurements

were below 10 nephelometric turbidity units. These parameters were recorded on residential well field
sample collection sheets, which are provided in Appendix E.
ANALYTICAL RESULTS
Grab and composite surface soil samples, as well as residential well samples, were submitted to an EPA
Contract Laboratory Program (CLP) laboratory for analysis for arsenic and lead. All samples were
analyzed in accordance with the CLP Statement ofWork for Inorganic Analysis Multi-Media, Multi-
Concentration (1LM05.4). Analytical results ofthe soil samples were compared to the EPA Region 4
RALs for arsenic and lead in residential soil. Analytical results ofthe potable water well samples were
compared to the EPA MCLs for arsenic and lead.
None of the potable water well samples contained arsenic or lead above their respective MCL (see Table
3 in Appendix B). Figures displaying potable water well sample locations are presented in Appendix A.
Laboratory analytical results for composite and grab soil samples indicated that none contained arsenic
above the RAL of 40 mg/kg. Analytical results revealed that composite surface soil sample CSB-SF-004
contained lead at a concentration of 1,000 J mg/kg, which is above the RAL of 400 mg/kg for residential
soil. Lead was detected above the RAL in 8 the 18 grab samples at concentrations ranging from 610
mg/kg in sample CSB-PS-003 to 69,000 mg/kg in sample CSB-PS-007. Figure 2 in Appendix A depicts
the sampling locations and lead results above RALs. Tables I and 2 in Appendix B present the laboratory
analytical results for the composite and grab surface soil samples collected from the residential and
commercial properties and along Psalms Street. Attachment 1 contains the EPA CLP analytical data
package.
CONCLUSION
The CSB site is comprised of about 20 parcels of land that encompass a footprint of approximately
15 acres of residential and commercial properties. The site is located along Psalms Street, an unpaved U-
shaped road, located between E 31 ^* Street and E 29 Street in Kannapolis, NC. Broken battery casings
and chips were reportedly dumped in the area and used for fill along Psalm Street and on residential and
commercial properties. The purpose ofthis RA was to characterize surface soil suspected of arsenic and

lead contamination due to the presence of battery chips. Potable water wells also were sampled to
determine whether they have been impacted by past disposal activities.
During the RA, Tetra Tech START conducted XRF screening of surface soils prior to sample collection.
Tetra Tech START then collected 28 composite surface soil samples, 18 grab surface soil samples, and
five residential potable well samples at the CSB site. Laboratory analysis ofthe soil samples revealed no
arsenic contamination exceeding the EPA RAL of 40 mg/kg. Lead was detected above the EPA RAL of
400 mg/kg in nine ofthe soil samples collected.
Based on the results of XRF screening and analytical laboratory analysis, levels of lead contamination
above EPA RALs are present at the CSB site. EPA will determine any further action concerning on-site
lead contamination.

Weedman at [phone] or Sandra Harrigan at [phone].

Report Narrative for Work Order C101404, Project: 10-0302
Inorganic Data Review and Validation Report
Site Name: Chapel Street Battery Dump Site, Kannapolis, NC
Case No.: 39563, ProjectNo. 10-0302, Work Order No. C101404
ELEMENT Sample IDs.: C101404-01 - 55, 57 - 59
Sampling Date: 03/30-31/2010
Laboratory Perfonning Inorganic Analysis: Chemtech Consulting Group, Mountainside, NJ
Date Received from Lab: 04/20/2010
Analyses conducted: Total metals (arsenic and lead only)
The ESAT Work Team has reviewed the above-captioned CLP data package consisting of forty-eight soil
samples for total metals analysis by ICP-AES and ten water samples for total metals analysis by ICP-MS analysis
according to the contract Statement ofWork and EPA guidelines. This package presents acceptable contractual
and technical perfonnance with qualifications. Additional details are provided below.
Exammation of blank samples revealed apparent low-level contamination with several elements. Reported
detection limits were adjusted as high as five times blank levels to discount possible false positives due to
contamination.
ICP-AES Analysis
PE Sample Results
The performance evaluation sample recoveries for metals in soil were all scored as within limits by the
web-based SPS Web software. Therefore, no data qualifiers were applied to sample results for metals in soil
based on these criteria.
Other QA/QC Results
The percent relative standard deviation was greater than 20% for plasma multiple exposures and the reported
result was greater than the method detection limit and less than the contract required quantitation limit for arsenic
results for Scnnple C101404-35. The affected sample result was considered unusable and qualified as "R".
Serial dilution percent difference for lead was 27% in SDG MD5LN4. All sample results for lead in SDG
MD5LN4 were considered estimated and "J" qualified.

The performance evaluation sample recoveries for metals in water were scored as within limits by the web-based
SPS Web software. Therefore, no data qualifiers were applied to water sample results for metals based on these
criteria.
Other QA/QC Results
There were no other QA/QC problems observed for metals analysis. Therefore, no data qualifiers were applied to
the sample results for metals based on these criteria.
A Stage 4 validation consisting of electronic and manual review was performed on the inorganic samples
submitted for this case.

DATA QUALIFIER DEFINITIONS
U The analj^e was not detected at or above the reporting limit.
CLP03 Baseline instability in calibration or preparation blanks
CLP04 Analyte repotted as potential false positive (% RSD > 20%, and result > MDL, btit < CRQL)
CLP36 Identification/Concentration of analyte not confirmed by ICP-MS.
J The identification ofthe analyte is acceptable; tlie reported value is an estimate.
Q-2 Result greater than MDL but less than MRL.
Q-5 Serial dilution precision outside inethod control limits
R The presence or absence ofthe analyte can not be determined from the data due to severe quahty control problems.
The data are rejected and considered unusable.
ACRONYMS AND ABBREVIATIONS
CAS Chemical Abstracts Service
Note: Analytes with no known CAS identifiers have beeu assigued codes begimimg with "E". the EPA ID as assigued by
the EPA Substance Registiy System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigued by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minunmn concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analjte concentration is greater than zero.
MRL Minimmn Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable
quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.
TIC Tentatively Identified Compound - An analyte identified based on a match with the instmment software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.
