Spray Irrigation Facility - Reuse Rules Apply

WQ0012667/GW96136
(Michael Allen: DEM SERG Review Engineer)
The Groundwater Section is in receipt of the subject permit application for the
proposed 15,000 GPD wastewater treatment system which will serve to treat the
wastewater generated by a 42-unit hotel, a 128-seat restaurant, and other operations
(see Figures 1 and 2) . The subject permit application is being submitted under the
new reuse rules. The initial amount of wastewater treated will be less than 15, 000
gallons per day, as this amount is a design figure which considers future growth.
The wastewater will be treated and discharged into a 75, 000 capacity, 5-day holding
pond (lined with a 40-ml liner) , then transferred to a 405,000 gallon capacity
irrigation holding pond (unlined) before being land -applied to approximately 2.88
acres on an application spray field.
The total area available for spray application of the wastewater is 7.56 acres (see
Figure 2), which is divided into sections. One section is a thin application area
(where the soil conditions have been determined to only be suitable for light
application of wastewater) , and a thick application area (where the soil conditions
have been determined to be suitable for heavier application of wastewater) . The thin
application area consists of 2.24 useable acres (at a recommended rate of 0.6 to 0.7
gallons per square foot per week) , while the thick application area consists of 5.32
useable acres (at a recommended rate of 0.9 to 1.0 gallons per square foot per
week) . The total area available and the recommended rates suggest that there is
approximately three times as much area as is needed to operate the system.
The 5-day holding pond is to be lined with a 40-ml liner, but apparently no liner
is proposed for the irrigation holding pond.
The configuration of the spray fields and the relative locations of nearby
residential wells would normally require the installation and monitoring of

groundwater wells at approved locations along the southern edge of the site
property, however, monitor wells will not be required due to the very low application
rate.
The Groundwater Section has reviewed the subject permit application and
recommends issuance of the permit with the following conditions;...
1. The interior surfaces of the 5-day effluent pond shall be completely lined with a
40-mil thick liner. Following installation and inspection of the pond liner, and
prior to waste disposal operations, certification of the liner's compliance with
approved construction specifications and the liner's integrity must be provided to
the Division of Environmental Management, Groundwater Section, by the project
engineer.
2. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations
in 15A NCAC 2L, Groundwater Classifications and Standards. The Compliance
Boundary for a disposal system constructed after December 31, 1983 is established
at either (1) 250 feet from the waste disposal area, or (2) 50 feet within the
property boundary, whichever is closest to the waste disposal area. The
Compliance Boundary for a system such as this one is at the property boundary.
An exceedance of Groundwater Quality Standards at or beyond the Compliance
Boundary is subject to immediate remediation action in addition to the penalty
provisions applicable under General Statute 143-215.6A(a) (1) .
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the
disposal systems midway between the Compliance Boundary and the perimeter of
the waste disposal area. Any exceedance of standards at the Review Boundary
shall require remediation action on the part of the permittee .
3. No land application of waste activities shall be undertaken when the seasonal high
water table is less than three feet below land surface.
4. Any groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
5. The annual administering and compliance fee must be paid by the Permittee within
thirty (30) days after being billed by the Division. Failure to pay the fee
accordingly may cause the Division to initiate action to revoke this permit as
specified by 15 NCAC 2H.0205(c) (4) .

Our office is in receipt 'of your August 6, 1996 letter
requesting additional informat-ion for the above referenced project.
The following additional information,is provided:
1- Information requested by the Groundwater Section
On August 7, 1996 I discussed with you the issues concerning
the use of Mountain Geology, Inc. professional geologist Mr.
Michael H. Owens for the soils evaluation. Our firm has been
working during the past year very closely with Mr. Ray Cox with
your office on the development of this project and a permit
modification for the spray irrigation system at Champion Hills
development. We were aware that the regulations state that the
soils evaluation is to conducted by a'"Soils Scientist". Mr. Owens
had conducted the original soils evaluation at Champion Hills and
it was requested to Mr. Cox that he be allowed to conduct the soils
evaluation for the permit modification at Champion Hills and the
work being planned at Dr. Reed's property.- Mr. Cox reviewed this
issue and since Mr. Owens had previous experience in this area,
verbally granted permission for the use of. Mr. Owens. Our firm
requested written confirmation of this approval, but this was never
provided.
Based on the authorization from your office, our firm
proceeded with contracting with Mr. Owens for the soils evaluation
for both Champion Hills and Dr. Reed's project. if we had any
inclination that this would not be acceptable, then an alternative
would have been pursued. At no time did your office.indicate that
an independent approval would be needed from the Ground Water Mr.

Section to use Mountain Geology. Mr. Owens has many years
experience in, the field of wastewater treatment facilities
utilizing land application and disposal. He works very closely
with many of the County .Health Departments in this region in the
approvals of septic system drainfields. Mr. Owens followed
standard practices in reviewing the soils at both of these projects
and we are fully satisfied that.his work has adequately.evaluated
these projects. It is apparent that the Ground Water Section was
unaware of the prior approval of Mr. Owens for work on these
projects. Mr. Owens also has expertise in the area of Ground Water
Geology and has, worked with the Ground Water staff on several
projects. It is our understanding that the regulations allow
alternatives to use of a "Soils Scientist" and it Ls requested that
the prior approval granted by Mr. Cox be honored. In our
conversation, you stated,that you did not see a problem with using
Mr. Owens for this project and we request that utilization .of
Mountain Geology, Inc. for the -soils evaluation report be allowed.
2- Information requested by the Permits and Engineering Unit.
With respect to the influent lift station, we have reviewed
the pump station design with respect to the cleaning velocity on a
three inch force. main. The'30 GPM'pump rate does have a cleaning
velocity slightly below the 2 ft/sec; therefore, the pump rate will
be increased to 50 GPM which has a cleaning velocity at 2.06
ft/sec. This can be accomplished with the same pump specified by
using a different diameter impeller.. The engineering report which
contained.the pump calculations has been revised along with sheet
7 of 7 of the plans which details .the influent lift station pump
specifications. In addition the pump rate, velocity, and head loss
chart of SDR 21 PVC has been -.included..
We hope this information is sufficient for the approval of
this project. Should you wish to discuss this project, please
contact our office at 704-697-7334.

INTRODUCTION
Dr. Harold M. Reed, M.D. has retained William G. Lapsley
and Associates, P.A. to assist in the preparation of permit
applications for a permit to construct an operate a land
application wastewater treatment facility to serve a proposed
42 unit hotel on Dr. Reed's property in Henderson County,
North Carolina. Dr. Reed is proposing to develop the hotel
project within the existing 85 acre site. The proposed hotel
is being planned on.a French Chateau architectural style with
formal gardens. Several options were considered for
wastewater disposal with land application of tertiary treated
wastewater under the .new reuse rules being chosen as the
preferred -alternative.
PROPOSED HOTEL FACILITIES AND ESTIMATED WASTEWATER FLOWS
The proposed hotel development and wastewater treatment
facility is being planned for the following facilities and
estimated wastewater flows:
FACILITY ESTIMATED WASTEWATER FLOW
42 Unit Hotel @ 120 GPD/unit 5,040 GPD
128 Seat Restaurant @ 40 GPD/Seat 5,120 GPD
40 Seat Bar @ 40 GPD/Seat = 1,600 GPD
Wine Bottling Wash Down = 500 GPD
Future Growth = 21740 GPD
Total Design Flow 15,000 GPD

PROPOSED WASTEWATER TREATMENT FACILITY
In evaluating wastewater treatment alternatives for the
proposed hotel development project three options were
considered, wastewater treatment and surface water discharge,
septic system and subsurface disposal, and wastewater
treatment with land application. A discussion of each of
these options follows:
WASTEWATER TREATMENT AND SURFACE WATER DISCHARGE
In order to have a site adequate for surface water
discharge it is necessary to have a receiving stream with
sufficient water flow to allow the discharge. The only
streams readily available to .the project area were the on site
spring fed streams and Kleine Lake. A request was made to the
USGS for stream flow statistics for the stream as it exists
the property below the lake. The USGS indicated the 7 day 10
year low flow for this stream and associated watershed would
be 0.0 cfs. Since the N.C. Division of Environmental
Management does not allow discharges to streams with zero 7
day 10 year flows, this option was eliminated from further
consideration.
SEPTIC SYSTEM AND SUBSURFACE DISPOSAL
The first non -discharge alternative consider was the use
of septic tanks and subsurface disposal by drainfields. In
order to serve the project 15,000 GPD it was estimated that
approximately five 3,000 GPD septic systems would be needed.
The associated drainfield areas and repairs areas would

approach 10 to 15 acres. The site was evaluated for possible
drainfield areas. Only one area exhibited potential for
drainfields along the Northern border of the site. There is
approximately 7 acres in this area that had sufficient soil
depth and gradual slope that were considered for. drainfield.
A meeting was held with the Henderson County Health Department
to discuss the feasibility of using septic systems for this
project. Approximately 3 of the 7 acres contained saprolitic
thin soils which according to the Health Department would not
be suitable for a .large system as being considered. The
Health Department will not allow systems in excess of 1,000
GPD in saprolitic soils. The better soils on site totaled
approximately 4.2 acres. In this area drainfields could
possibly be used, but there would not be sufficient room for
the entire 15,000 GPD projected flow. The remaining property
on the site was considered unsuitable due to either existing
surface wasters and steep slope. In addition it is the
consultants opinion (also shared by the Health Department)
that septic systems do not provide the reliability for long
life to serve a project of this magnitude. With these
limitations, septic systems were eliminated from futher
consideration.
WASTEWATER TREATMENT AND LAND APPLICATION
Having eliminated surface discharge and subsurface
disposal from consideration, attention was directed to the
feasibility, of using land application as the means of
wastewater treatment and disposal. The seven acre area being

considered for drainfields was evaluated by Mountain Geology,
Inc. to determine the feasibility of utilizing this area for
land application of tertiary treated wastewater. The system
would be developed under the Division's Reuse Rules which have
recently been modified to promote these type systems.
Mountain Geology, Inc. found the 7 acre area to contain two
types of'soils, classified as thick and thin areas in Mountain
Geology, Inc. report contained in the appendix. The thin
areas approximately 3 acres were thin depth 15 to 28 inches of
clay loam to sandy loam soils with 20% shist fragments. Even
though usable for land application, this area would be limited
to loading rate of 0.6 - 0.7 gallons per square foot per week.
The thick area contained deeper clay soils 28 to 84 inches.
thick with an allowable application rate of 0.9 - 1.0'gallons
per square foot per week. Based on the allowable loaded rate
in the thick area soils it was determined that only 2.54 acres
would be needed for the 15,000 GPD wastewater flow. Since
sufficient land.area was available in the thicker soils this
area was chosen for the development of a land application
spray field. The thin area soils were chosen for the
development of the wastewater treatment facility and the
associated holding ponds. A copy of the Mountain Geology,
Inc. report is included in the appendix. Sheet 3 of 7 shows
the location of the 7 acre area and soil test boring
locations.

PROPOSED WASTEWATER TREATMENT FACILITY
The N.C. Division of Environmental Management has recently
developed rules to allow the reuse of high quality treated
wastewater, effluents by various uses including land
application. Since Dr. Reed's property contained several
acres suitable for the application of tertiary treated
wastewater, the development of a wastewater treatment and land
application system was chosen as the means of providing
wastewater treatment for the proposed hotel project. The
major items included in the wastewater treatment system are as
follows:
- Influent sanitary sewer lift station and force main
- Package Tertiary Extended Aeration Wastewater Treatment
Containing Flow Equalization, Dual Aeration Basins, Dual
Clarifiers, Dual Teritary Filters, Effluent Disinfection,
Instrument Turbidity & Flow Measurement, Standby Power
Effluent Holding Pond, 5 Day Capacity, Lined 40 ml Liner
- Irrigation Pond, 405,000 Gallon Capacity
Irrigation Pump House
Irrigation Spray Field, 2.88 Acres Wetted Area
The mechanical tertiary wastewater treatment plant is a
packaged wastewater treatment facility. Sheet 4 of 7 shows a
typical facility layout utilizing equipment available from
Pollution Control, Inc. It is planned to use this type of
standard package plant equipment for the wastewater treatment
plant. The effluent holding pond and irrigation ponds will be

construct on site. Treated wastewater will flow by gravity to
the effluent holding pond and then to the irrigation pond.
The irrigation pump house and wet well will be set such that
the water level in the wet well will fluctuated with the
irrigation pond. The irrigation pump system will be a package
unit to be located within a small pump house located above the
wet well. A standard 4 ft. diameter precast concrete manhole
will be used for the wet well.. The irrigation spray field
will utilize Toro spray heads as show on sheet 6 of 7. These
spray heads are capable of delivering up to 74 GPM on a 100
ft. radius application. This will allow the number of spray
heads to be kept to a minimum.

SYSTEM WATER BALANCE
A water system balance was utilize to establish the size
of the irrigation pond. Elements taken into consideration are
outline and discussed as follows:
EVAPORATION/TRANSPIRATION
Evaporation and Transpiration (ET) data was obtained
through the Henderson County Soil Conservation Service (SCS)
which shows the ET values for this area to range from 0.6 to
4.25 inches per month. The appendix contains this data in
graph form provided by SCS.
PERMEABILITY
The soil permeability data was provided'by the SCS and
verify by Mountain Geology, Inc. to be 0.6 to 2.0 inches per
hour. If you assume that the site would constantly provide
a permeability of 0.6 to 2.0 inches per hour, then no storage
would be needed. However, during wet periods the soils would
become saturated resulting in runoff. In order to establish
a monthly permeability rate it was assumed that the site would
reach saturation during rainfall events and that the site
would provide only 6.5 inches/month of permeability. This
gave a total loss from the site ranging from 7.1 to 10.65
inches per month.
PRECIPITATION
Precipitation data was obtained from the Climatic Center
in Asheville, N.C. and included in the appendix.
Precipitation data for this area ranged from 3.25 to 4.52

inches per month. This was based on the current record period
from 1965 through 1994.
ALLOWABLE IRRIGATION AND STORAGE REQUIREMENTS
Using the total site loss and the precipitation data the
allowable irrigation ranges from 3.58 to 6.52 inches per
month. This results in the maximum cumulative storage at
maximum of 5.16 inches during the month of March. Using the
application area of 2.88 acres and the 5.16 inches this
results in the maximum required storage of 405,000 Gallons.
The irrigation pond has been sized accordingly at 405,000
gallons which at design flow of 15,000. GPD gives 27 days of
storage. With the 5 day effluent holding pond, the system has
32 days total storage capacity.

analysis.

SPRAY FIELD
The proposed spray field is a portion of the 7 acres evaluated
by Mountain Geology, Inc. and found suitable for application
of treated wastewater. The spray field will be limited to the
thicker soils area where the allowable application rates are
0.9 to 1.0 gallons/sq.ft./week. At the an average allowable
application rate of 0.95 gallons /sq.ft. /week and average daily
flow of 15,000 GPD the require spray field area is as follows :
(15,000 GPD x 7 days/wk)/0.95 gallons/sq.ft./wk =
110,526 sq.ft or 2.54 acres
The spray field provided will be four 200 ft. diameter
spray areas totaling 2.88 acres ( See Sheet 2 of 7 of the
design plans).
The existing mixed hardwood and pine forest will be left
as the vegetative cover. This was recommended by both SCS and
Mountain Geology, Inc. as the best suited vegetative cover.
The large mature trees will greatly increase the. transpiration
of moisture from the site. The existing well established root
systems and thick forest floor mat will be able to absorb the
applied treated wastewater minimizing potential for.runoff.
The spray areas will be kept clear of unwanted undergrowth
that would inhibit distribution from spray heads.

SUMMARY AND RECOMMENDATIONS
Dr. Harold M. Reed. M.D. is requesting a permit for
authorization to construct and operate a 15,000 GPD land
application wastewater treatment facility. Based on the evaluation
of the site it was found that land application was the most
environmentally sound option for providing wastewater treatment for
the proposed hotel complex. Since tertiary treatment is being
provided prior to land application, this type of wastewater
treatment facility is fare superior to surface water discharge and
subsurface disposal type facilities. It is recommended that the
request for permit be approved.

PRELIMINARY SOILS EVALUATION
FOR
EFFLUENT SPRAY IRRIGATION
Summary
Soil and saprolite were examined at 15 auger boring locations in the western portion of this property.
Two material types are present; a "thick" clay loam to silt loam soil - saprolite sequence overlying
felsic gneiss, and "thin" rocky clay loam soil overlying schist.
No indications of groundwater were encountered.
I recommend a 0.9 - 1,0 gallons per square foot application rate for the "thick" sequence and 0.6 - 0.7
gallons for the "thin" material.
Methods of Evaluation
On 05/10/96 soil material was collected and examined in 15 boring locations. Borings ranged from
15 to 84 inches deep. Field observations include the nature of the material, soil texture, soil structure,
and,
if present, groundwater indications.
Soil Characteristics
The "thick" sequence ranges from 28 to 84 inches thick, borings average 63 inches deep. The
overlying soil averages 43 inches thick and has a clay loam to silty loam texture. The underlying saprolite
(where present) averages 33 inches thick and has a silty. loam to sandy loam texture. This sequence is
present in about 75% of the area considered for effluent application.

The "thin" sequence ranges from 15 to 28 inches thick, It is a clay loam to sandy clay loam soil,
containing about 20% schist fragments. It covers about 25% of the area considered.
None of the borings encountered any indication of groundwater.
Recommendations
Soil Conservation Service information suggests the minimum permeability for all this material is 0.6
inches/hour, and in the 0.6 to 2.0 inch/hour range.
I recommend maximum application rates on a once - weekly basis.
thick sequence 0.9 - 1.0 gallons per square foot
thin sequence 0.6 - 0.7 gallons per square foot
These are significantly less than the SCS permeability rates.

cessive soil losses. The production potential is high for
hay and pasture plants such as tall fescue, bluegrass,
orchardgrass, clover, and sericea lespedeza. The potential
for apples is high, but slope is a limitation when the soil is
used for this purpose.
This soil has moderate potential for most urban uses.
Permeability and slope limit the performance of septic
tank absorption fields, but this limitation can be reduce([
in places by modifying the field or increasing the size of
the filter area. Low shear strength and slope limit per-
formance and increase maintenance needs when this soil
is used for dwellings or local roads.
This soil has high potential for hardwood~ and pines or
other conifers. There are no major limitations to
woodland use and management. Capability subclass IIIe;
woodland group 2o.
llyE—IIayesville loam, 15 to 25 percent slopes. This
well (trained soil is on smooth ridges at the lower eleva-
tions. Areas are irregularly shaped and are 6 to 30 acres
in size.
Typically, the surface layer is (lark brown loam 4 inches
thick. The subsurface layer is brown loam 4 inches thick.
The subsoil is :36 inches thick. The upper part is yellowish
red clay loam, the middle part is yellowish red and red
clay loam, and the lower part is red sandy clay loam and
sandy loam. The underlying layer is 68 inches thick. The
upper part is red saprolite that crushes to sandy loam,
and the lower part is gray and light gray soft saprolite
that crushes to sandy loam.
Included with this soil in mapping are small areas of
soils that have a surface layer of fine sandy loam, and in
some places there are some small areas of eroded soils.
Also included are small areas of Evard and Fannin soils.
The organic -matter content of the surface layer is
medium. Permeability is moderate, and available water
capacity is medium to high. Shrink -swell potential is low.
Reaction is very strongly acid or strongly acid throughout
the profile unless the soil is limed. Depth to bedrock is
more than 60 inches. The seasonal high water table is at a
depth of more than 6 "feet.
Most areas of this soil have been cleared and are used
for crops or pasture.
This soil has medium potential for most locally grown
crops such as corn, tobacco, beans, and cabbage, but the
hazard of erosion is very severe when the soil is cul-
tivated. Practices such as minimum tillage, using a conser-
vation cropping system that has long-term sod crops, con-
tour farming, grassing of waterways, and establishing
diversions help to reduce soil losses, conserve moisture,
and maintain production. The production potential is
medium for hay and pasture plants such as tall fescue,
bluegrass, orchardgrass, clover, and sericea lespedeza.
Proper pasture management helps to insure adequate
protective cover. The potential for apples is medium, but
slope is a limitation to the operation of spraying and har-
vesting equipment.
This soil has low potential for most urban uses, such as
septic tank absorption fields and dwellings and roads,
because of slope. Extensive modification of the. soil or
major planning, special design, and intensive maintenance
are generally required to overcome the limitation of slope.
Erosion is a hazard where ground cover is removed.
Permeability and slope limit the performance of septic
tank filter fields.
This soil has high potential for hardwoods andpines or
other conifers. Slope is the main limitation to woodland
use and management. Capability subclass IVe; woodland
group 2r.
Ko—Kinkora loam. This poorly drained, nearly level
soil is on low terraces along the larger streams. Areas are
irregularly shaped and are 4 to 20 acres in size.
Typically, the surface layer is dark gray loam 7 inches
thick. The subsoil is mottled gray clay loam or clay 26
inches thick. The underlying layer, to a depth of 60
inches, is.mottled gray clay.
Included with this soil in mapping are small areas of
Hatboro and Delanco soils and a few areas of a soil that
is not so wet as Kinkora soils.
The organic -matter content of the surface layer is low
to medium. Permeability is moderately slow, and available
water capacity is high. Shrink -swell potential is moderate.
Reaction is. very strongly acid or strongly acid throughout
the profile unless the soil is limed. Depth to bedrock is
more than 72 inches. The seasonal high water table is at
or near the surface for 2 to 6 months each year. This soil
is subject to occasional, brief flooding.
Most areas of this soil are cleared and used for crops or
pasture.
This soil has medium production potential for corn and
water -tolerant plants such as tall fescue, clover, and reed
canarygrass. Production is limited because of flooding and
a seasonal high water table.
This soil is slow to warm up in spring. Management
practices such as minimum tillage, using cover crops, in-
cluding legumes and grasses in the conservation cropping
system, and (training the surface help to maintain soil
tilth and production potential. Wetness limits the use of
this soil for apple orchards. Winter crops, such as wheat,
are commonly damaged by excessive wetness.
This soil has low potential for most urban uses. Slow
permeability, a seasonal . high water table, and flooding
limit the use of the soil for building sites, septic tank ab-
sorption fields, and roads. The limitation of flooding and
the moderate shrink -swell potential are difficult and
costly to overcome. Special design and intensive main-
tenance are needed for roads and dwellings.
This soil has high potential for water -tolerant hard-
woods and pines. Wetness is the main limitation to
woodland use and management. Capability subclass IVw;
woodland group 2w.
PoE—Porters stony loam, 15 to 25 percent slopes.
This well drained soil is on mountainsides. Areas are elon-
gated and are 6 to 25 acres in size. Stones cover 5 to 15
percent of the surface.
Typically, the surface layer is very dark grayish brown
stony loam 6 inches thick. The subsoil is 26 inches thick.

water from seepage, nearly continuous rainfall, or a combination of
these.
Poorly drained. —Water is removed so slowly that the soil is satu-
rated periodically during the growing season or remains wet for
long periods. Free water is commonly at or near the surface for
long enough during the growing season that most mesophytic crops
cannot be grown unless the soil is artificially drained. The soil is not
continuously saturated in layers directly below plow depth. Poor
drainage results from a high water table, a slowly pervious layer
within the profile, seepage, nearly continuous rainfall, or a combina-
tion of these.
Very poorly drained. —Water is removed from the soil so slowly
that free water remains at or on the surface (luring most of the
growing season. Unless the soil is artificially drained, most
mesophytic crops cannot be grown. Very poorly drained soils are
commonly level or depressed and are frequently ponded. Yet, where
rainfall is high and nearly continuous, they can have moderate or
high slope gradients, as for example in "hillpeats" and "climatic
moors.
Erosion. The wearing away of the land surface by running water, wind,
ice, or other geologic agents and by such processes as gravitational
creep.
Erosion (geologic). Erosion caused by geologic processes acting over
long geologic periods and resulting in the wearing away of moun-
tains and the building up of such landscape features as flood plains
and coastal plains. Synonym: natural erosion.
Erosion (accelerated). Erosion much more rapid than geologic ero-
sion, mainly as a result of the activities of man or other animals or
of a catastrophe in nature, for example, fire, that exposes a bare
surface.
Excess fines. Excess silt and clay. The soil does not provide a source of
gravel or sand for construction purposes.
Favorable. Favorable soil features for the specified use.
Flooding. The temporary covering of soil with water from overflowing
streams, runoff from adjacent slopes, and tides. Frequency, dura-
tion, and probable dates of occurrence are estimated. Frequency is
expressed as none, rare, occasional, and frequent. None means that
flooding is not probable; rare that it is unlikely but possible under
unusual weather conditions; occasional that it occurs on an average
of once or less in 2 years; and frequent that it occurs on an average
of more than once in 2 years. Duration is expressed as very brief if
less than 2 days, brief if 2 to 7 days, and long if more than 7 days.
Probable dates are expressed in months; November -May, for exam-
ple, means that .flooding can occur during the period November
through May. Water standing for short periods after rainfall or
commonly covering swamps and marshes is not considered flooding.
Grassed waterway. A natural or constructed waterway, typically broad
and shallow, seeded to grass as protection against erosion. Conducts
surface water away from cropland.
Horizon, soil. A layer of soil, approximately parallel to the surface, hav-
ing distinct characteristics produced by soil -forming processes. The
major horizons of mineral soil are as follows:
0 horizon. —An organic layer, fresh and decaying plant residue, at
the surface of a mineral soil.
A horizoie.—The mineral horizon, formed or forming at or near the
surface, in which an accumulation of humified organic matter is
mixed with the mineral material. Also, a plowed surface horizon
most of which was originally part of a B horizon.
A2 horizon. —A mineral horizon, mainly a residual concentration of
sand and silt high in content of resistant minerals as a result of the
loss of silicate clay, iron, aluminum, or a combination of these.
B horizon. —The mineral horizon below an A horizon. The B horizon
is in part a layer of change from the overlying A to the underlying
C horizon. The B horizon also has distinctive characteristics caused
(1) by accumulation of clay, sesquioxides, humus, or a combination
of these; (2) by prismatic or blocky structure; (3) by redder or
browner colors than those in the A horizon; or (4) by a combination
of these. The combined A and B horizons are generally called the
solum, or true soil. If a soil lacks a B horizon, the A horizon alone is
the solum.
C horizon. —The mineral horizon or layer, excluding indurated
bedrock, that is little affected by soil -forming processes and does
not have the properties typical of the A or B horizon. The material
of a C horizon may be either like or unlike that from which the
solum is presumed to have formed. If the material is known to
differ from that in the solum the Roman numeral II precedes the
letter C.
R layer. —Consolidated rock beneath the soil. The rock commonly
underlies a C horizon, but can be directly below an A or a B
horizon.
Irrigation. Application of water to soils to assist in production of crops.
Methods of irrigation are —
Border. —Water is applied at the upper end of a strip in which the
lateral flow of water is controlled by small earth ridges called
border dikes, or borders.
Basin. —Water is applied rapidly to nearly level plains surrounded
by levees or dikes.
Controlled hooding. —Water is released at intervals from closely
spaced field ditches and distributed uniformly over the field.
Corrugation. —Water is applied to small, closely spaced furrows or
ditches in fields of close -growing crops or in orchards so that it
flows in only one direction.
Furrow. —Water is applied in small ditches made by cultivation im-
plements. Furrows are used for tree and row crops.
Sprinkler. —Water is sprayed over the soil surface through pipes or
nozzles from a pressure system.
Subirrigation.—Water is applied in open ditches or tile lines until
the water table is raised enough to wet the soil.
Wild hooding. —Water, released at high points, is allowed to flow
onto an area without controlled distribution.
Large stones. Rock fragments 10 inches (25 centimeters) or more
across. Large stones adversely affect the specified use.
Loam. Soil material that is 7 to 27 percent clay particles, 28 to 50 per-
cent silt particles, and less than 52 percent sand particles.
Low strength. Inadequate strength for supporting loads.
Morphology, soil. The physical makeup of the soil, including the tex-
ture, structure, porosity, consistence, color, and other physical,
mineral, and biological properties of the various horizons, and the
thickness and arrangement of those, horizons in the soil profile.
Parent material. The great variety of unconsolidated organic and
mineral material in which soil forms. Consolidated bedrock is not
yet parent material by this concept.
Percolation. The downward movement of water through the soil.
Peres slowly. The movement of water through the soil adversely affect-
ing the specified use.
Permeability. The quality that enables the soil to transmit water or air,
measured as the number of inches per hour that water moves
through the soil. Terms describing permeability are very slow (less
than 0.06 inch), slow (0.06 to 0.20 inch), moderately slow (0.2 to 0.6
inch), moderate (0.6 to 2.0 inches), moderately rapid (2.0 to 6.0
inches), rapid (6.0 to 20 inches), and very rapid (more than 20
inches).
Piping. Moving water forms subsurface tunnels or pipelike cavities in the
soil.
Profile, soil. A vertical section of the soil extending through all its
horizons and into the parent material.
Reaction, soil. The degree of acidity or alkalinity of a soil, expressed in
pH values. A soil that tests to pH 7.0 is described as precisely
neutral in reaction because it is neither acid nor alkaline. The
degree of acidity or alkalinity is expressed as —
pH
Extremely acid ..................................................Below
4.5
Very strongly acid..............................................4.5
to 5.0
Stronglyacid........................................................5.1

dries out by evaporation, but not much moisture is
lost after the top layer of the soil becomes dry. The
dry layer at the top makes it difficult for water to
come to the surface from deeper layers. During the
first 24 hours after a rain, bare, wet soil may return
as much as 'A inch of water to the air in summer.
After the top of the soil dries, however, it may take
5 to 10 days for another ;/3 inch of moisture to
evaporate.
By far the greatest amount of evaporation is
through the plants that cover the state: the trees,
crops, lawns, weeds, and other vegetation. The water
enters the roots from the soil and travels up to the
leaves where it is evaporated by the process called
transpiration.
Unlike rainfall, evaporation is a steady process that
varies only slightly from week to week. It is also very
uniform over the entire state. Contrary to what one
might expect, the type of plant makes little difference
in the Amount of evaporation that occurs. `*hen the
soil is well supplied with water, a forest evaporates
no more per unit area than a lawn, nor a field of corn
more than alfalfa. Plants undergoing drought stress
transpire less than healthy plants, depending on the
severity of the drought, and dormant -vegetation does
not transpire at all.
There is a continuous contest between evaporation
and rainfall. When rainfall exceeds evaporation, the
soil contains ample water. When evaporation exceeds
rainfall for any lengthy period, however, the soil will
have a deficiency of water. The average values of
evaporation versus rainfall for three locations in
North Carolina are given in Figure 11.
In winter, the amount of water received through
rainfall is considerably greater than that Iost by
evaporation. In the early summer the picture is dif-
ferent. As can be seen from Figure 11, rainfall at that
time of year averages somewhat less than evapora-
tion, This means that the soil begins to dry, a situa-
tion that occurs often in the warm season over much
of the nation. Furthermore, in summer the rains do
not come regularly but occur in unevenly spaced
showers. During some of these showers the rain falls
faster 'than the soil can absorb it or in a greater
amount than the soil'can hold. Thus, some of the rain-
fall is lost in runoff from the earth's surface. This
means that the effective rainfall is somewhat less
than the total received.
North Carolina rarely experiences severe -droubhts
such as those that occur at times in the Great Plains.
However, as is true with most other "humid" areas
of the nation, North Carolina does have recurring
deficiencies of rainfall. The state actually receives suf-
ficient rainfall almost every year, but in some years
much of it comes in the winter when it is not needed
by crops_ Almost every summer a certain amount of
