ABSTRACT
Aerial photography taken of waste plumes from Kraft pulp mill ocean
outfalls was shown to be an effective tool in the study of waste dis-
posal sites. This technique is not limited by sea conditions and
permits monitoring and evaluation of outfall sites throughout the year.
Photography taken at one instant provides comprehensive information
throughout the waste field. Manpower requirements and costs for this
method are considerably less than for conventional boat sampling surveys.
Field studies were conducted on the waste plumes from Kraft pulp mill
ocean outfalls at Newport and Gardiner, Oregon and Samoa, California.
Waste concentrations were measured by conventional boat sampling tech-
niques while aerial photography was taken of the outfall area from
altitudes ranging from 3,000 to 11,000 ft. Computerized procedures were
used to compute water currents, waste concentrations, toxicity zones
and diffusion coefficients from the photography.
The highest concentration measured directly over the outfalls was.2.3
percent waste by volume and the maximum area of influence with concen-
trations greater than 0.2 percent waste was 155 acres. The maximum
concentration determined over the outfall for each field study was
generally less than that shown to have a detrimental effect on young
salmon for a 14-day exposure.
Surface water current was found, to be the dominant factor in the result-
ing plume pattern. During periods of low current velocities in the
receiving water, the hydraulic head created by the effluent source was
a significant factor in the resulting plume shape. The steady state
form of the Fickian diffusion equation and unidirectional transport
velocity was not applicable to the majority of the observations.
Temperature was found not to be an effective tracer for tracking the
plume or for estimating waste concentrations since the resulting plume
temperature may be greater than, less than or equal to the surrounding
ocean temperature.
This report was submitted in fulfillment of Grant WP-00524 under the
sponsorship of the Federal Water Quality Control Administration.

SECTION I
CONCLUSIONS
1. Aerial photography provides comprehensive information on the marine
waste disposal process and is an effective tool in monitoring and eval-
uating ocean outfall sites throughout the year.
2. The maximum concentration measured over the outfall for each field
study was generally less than the range of 1.8 to 3.3 percent Kraft pulping
waste that has been shown to be detrimental to young salmon for a 14-day
exposure. The highest concentration measured during the study was 2.3
percent waste by volume and the maximum area of influence with concentrations
greater than 0.2 percent waste was 155 acres.
2
3. Diffusion coefficients measured ranged from 2.0 to 14 ft /sec. The
steady state Fickian diffusion equation with a unidirectional transport
velocity was not applicable to the majority of the observations.
4. Temperature is not an effective tracer in tracking the plume or for
estimating concentrations in the waste field since the resulting plume
temperatures may be greater than, less than or equal to the surrounding
ocean temperature.
5. Surface water current is the dominant factor in the resulting plume
pattern at the three locations observed.
6. Surface spreading of the waste field over the outfall must be con-
sidered to adequately explain the resulting plume shape.
-------
SECTION II
RECOMMENDATIONS
It is recommended that observations of the Newport outfall be
conducted for a wide range of sea and weather conditions. Field studies
made throughout the year using aerial photography with limited boat
sampling would provide valuable information for the design and operation
of ocean outfalls. Such a study combined with dye drops from the air-
craft would indicate seasonal changes in waste disposal conditions,
current velocities, diffusion coefficients, plume patterns and foaming
tendency. Sufficient data would be available to relate the waste field
characteristics to natural parameters such as tide, wind, state of the
sea, and river flow. The study would also provide information for sizing
the holding ponds for operation of existing outfalls.
While all the photography would not be suitable for automatic
computer processing, it would still give information on the current
velocities, plume size and pattern and foaming tendency.
It is also recommended that a critical analysis of actual held
conditions versus the original design predicitions be made for the
several ocean outfalls in Oregon and at Eureka, California. Such a
study will indicate areas of design deficiencies and will improve the
technology of ocean outfall disposal.
It is recommended that further analysis be made of the area of
influence within various concentration zones. This study would compare
these data with information now available from the many biological
studies which have related Kraft pulp mill effluent concentrations to
biological effects.

SECTION III
INTRODUCTION
Pollution of near shore coastal waters and estuaries is a serious
problem in the Pacific Northwest since these waters form an integral
part of the economy of the region in addition to their high recreational
and esthetic value to the people. Sports and commercial fishing combined
form a major aspect of the economic and recreational values of the water
resources. These uses combined with the other important values of water,
make it essential that industrial growth to provide jobs be accomplished
without despoiling the environment.
This project on analysis of ocean outfalls from Kraft pulp mills
is a part of an overall investigation that has been in progress since
1964. Investigations during the first years of this project included
laboratory studies on the development of bioassay methods for assessing
water quality impairment from the discharge of Kraft pulp mill wastes
into marine waters. Engineering studies on treatment of components of
the waste were also undertaken during the first years of this study.
Research during the last two years of the project were directed towards
investigations of the area and degree of water quality effects from
Kraft pulp mill ocean outfalls. This report includes only the work
accomplished during the last two years of the project since the previous
research has been adequately described in the annual progress reports,
published papers, and theses.
Disposal of wastes from the pulp and paper industry presents a
serious water quality problem. In the area of Oregon and Washington,
lying between the Pacific Ocean and the Cascades, there are now 49 pulp
mills producing approximately 17,000 tons of pulp daily (Stanford, 1969).
A variety of pulping processes are used including sulfite, Kraft, semi-
chemical , and mechanical.
Primarily because it produces a stronger, more versatile pulp
at lower cost, the Kraft pulping process has become the dominant method
for production of pulp and paper. In 1920 the total production of pulp
in the United States was approximately 3.8 million tons annually of
which approximately 4.5% was produced utilizing the Kraft process. By
1966 approximately 63% of the nationwide production of paper pulp was
produced by the Kraft process.
Growth of Kraft process for pulp manufacturing in Oregon has
been similar to that experienced nationwide. In 1939, pulp production
capacity in Oregon was approximately 575 tons per day of which 20% was
by the Kraft process. By 1969, pulp production in Oregon had risen to
more than 7,000 tons per day of which 65% (4,950 T/day) was produced
by the Kraft process.

The Kraft process of pulp production discharges about 20,000
gallons of liquid waste per ton of pulp, with a population equivalent Of
about 400 per ton of pulp. Treatment and disposal of waste in a satis-
factory manner is a major problem of the pulp and paper industry.
Many of the newer mills have been constructed on or near tidal
estuaries or the open coast. Some of the new mills have added to the
problems created by many of the older mills which were already located
on marine waters. With the addition of new mills and increased production
in the older mills, significant volumes of waste are being discharged
into marine waters.
One of the primary problems created when Kraft pulp mill effluent
is discharged into marine waters is the toxic effect on the biological
population. Although numerous investigators have conducted tests on
acute toxicity there is little agreement on permissible concentrations.
Bioassay results are generally reported in terms of a median tolerance
limit for a specified period of exposure to a specific organism.. Table
1 shows the results of some of these studies.

It can be seen from Table 1 that tolerance level varies between test
organisms.
O'Neal (1966) found that the toxicity of Kraft waste as measured
by bioassays on the bay mussel is biologically degradable but there was
no apparent correlation between B.O.D., P.B.I, and toxicity degradation.
Sprague and McLeese (1968), in tests with salmon parr and lobster larvae
have shown that toxicity degradation rates varied considerably between
the two test animals.
While the TL is probably the most reproducible statistic from
the test and provides valuable information on toxicity; it cannot be
applied to actual field problems for determining the permissible con-
centration in receiving waters since the premise of allowing a stated
mortality is unacceptable as a water quality control policy.
The Washington State Department of Fisheries (1960) has conducted
extensive tests on the toxicity of Kraft pulp wastes to salmon and trout.
The tests were conducted in flowing sea water with a salinity of 35 parts
per thousand (ppt) and at temperatures about 50°F. The tests showed that
the concentration which produced no obvious harmful effects over a 14-
day exposure period was usually between 1.8 percent and 3.3 percent by
volume. Longer exposure periods led to somewhat lower levels. Signif-
icant mortalities occurred at concentrations greater than 3.3 percent
over the 14-day period. This study also indicated that there was little
significant difference in the toxicity in wastes between mills producing
bleached and unbleached Kraft pulp.
Alderdice and Brett (1957) conducted bioassays to determine the
toxic effect of full bleach Kraft effluent on young sockeye salmon. The
tests were conducted in 20 ppt salinity sea water and at 18°C. Results
indicated that at concentrations below 4.8 percent there was no mortality.
Kraft pulp mill effluent when discharged into marine waters will
some times create foam on the water surface. Courtright and Bond (1969)
found the foam to be about five times more toxic than the whole mill
effluent as measured by bioassays with the mussel larvae (Mytilus edulis).
While on the water surface, the foam is unsightly but probably does not
create a great threat to marine life. If the foam accumulates on the
beach, it can result in lethal concentrations to some marine life in the
littoral region.
The maximum concentration of Kraft pulp waste which will not
adversely affect marine life is difficult to define when one considers
the variable composition of the effluent, possible separation of the
waste into fractions upon contact with the sea water, variation in tol-
erance levels between animals, avoidance reaction of some species and the
lack of knowledge on chronic toxicity.
-------
Since 1955 six Kraft pulp mills have been constructed on the
Pacific Coast of Oregon, Washington and Northern California. In each
case effluent disposal involves the use of ocean outfalls that have been
designed and constructed for the purpose of protecting water quality
in the near shore environment. The design of these facilities has given
consideration to: a) dilution requirements for protection of aquatic
resources, b) prevention of objectionable aesthetic conditions on
adjacent beaches and the near shore area, and c) the physical circum-
stances for initial construction and continued protection of the outfall
against the ravages of the sea.
The typical outfall extends into the ocean and usually terminates
with a diffuser section where the flow is divided into a number of small
jets which discharge the waste into the receiving water. The jet of
waste is subjected to a momentum force and to a buoyant force which is
proportional to the density difference between the effluent and the
receiving water. As the jet of waste rises towards the surface, it mixes
with the ambient fluid and both its momentum and buoyancy per unit volume
decrease. The mixing causes a waste field to be formed either at the
surface or submerged below the sea surface depending on the hydrography
of the site and the initial jet dilution.
Ocean outfalls along the Pacific coast are in general located on
the relatively shallow coastal shelf. The turbulence in this area is
usually sufficient to prevent density stratification in the receiving
water. Under these conditions the effluent, being less dense than sea
water, will generally rise to the surface to form a surface waste field.
After the initial dilution due to jet diffusion, the waste is transported
from the site by current action and continues to mix and spread by natural
turbulence in the ocean.
If density stratification exists in the receiving water and a
submerged plume is formed, the waste field is esthetically more pleasing
than a surface field but may be potentially more dangerous to the marine
life. The submerged plume will create an oxygen sink where the reaeration
rates are generally lower than at the surface. Under these conditions
less energy from the wind will be available for diffusion. Also con-
centrations may be higher than for a surface plume as less vertical rise
is available for jet diffusion.
Probably the most extreme condition for ocean outfall waste dis-
posal occurs during calm periods when current velocities in the receiving
water approach zero. Only the jet diffusion is available for dilution
and the waste field forms a pond above the diffusers since only the
hydraulic head created by the discharging effluent is available for move-
ment of the waste field. Under these unfavorable conditions, a large
waste field can form with nearly uniform concentrations throughout and
odor can be a serious problem on the nearby beach.
-------
Once the water quality standards have been set for the receiving
water, these can be met through a combination of effluent treatment,
outfall location and design, and/or operation of holding ponds to store
the waste during adverse disposal conditions.
The purpose of the research included in this report was to study
the water quality impairment near existing ocean outfalls. In addition
to the area and extent of Kraft pulp mill outfall influence on water
quality, this study also includes diffusion analysis of the waste field.
Natural conditions which influence mixing, water currents, foaming of the
effluent, and the establishment of subsurface plumes are discussed.
-------
SECTION IV
METHODS AND PROCEDURES
In order to study the waste field created by Kraft pulp mill
ocean outfall, both aerial photography and boat sampling were utilized.
The concentrations determined by boat sampling provided standardization
data for the aerial photography. Concentrations throughout the waste
plume, water currents and diffusion coefficients were computed from the
aerial photography.
Field work was conducted at three outfall locations as shown in
Figure 1. These are the Georgia Pacific outfall off Newport, Oregon,
the International Paper Company outfall near Gardiner, Oregon, and the
Georgia Pacific outfall near Samoa, California. The general procedure
employed in the collection of data was to take aerial photography of the
waste field and at the same time sample the plume by conventional methods
from a boat.
Accurate horizontal control for positioning the boat and orient-
ation of the photography was essential. Shore control was provided by
a beach traverse extending between existing control stations at each of
the three locations. Horizontal and vertical angles were measured with
a Wild T-3 theodolite and the distances along the traverse were measured
with either a tellurometer or a geodimeter. Since the geodimeter and
tellurometer measure slope distance, the station elevations were deter-
mined by reciprocal vertical angles. All positions for this study were
computed on the state plane coordinate system so that existing C§GS, GS,
and USE control could be used when available. Since most published maps
and charts include a state plane coordinate grid, this system provides a
common base for positioning.
Traverse stations were permanently marked with steel markers.
In order to identify the control stations on the photography, the beach
stations were also marked with white or black cloth. Details of the
beach traverses are given in appendix A.
In addition to shore control, horizontal control was required
in the water for photo orientation. This was accomplished by the use
of marker buoys which were set from the survey boat and their position
determined by triangulation from the shore stations.
During the 1968 field season ten buoys were permanently anchored
with 500-lb. concrete anchors. However, only three buoys were required
during the 1969 season. These temporary buoys were set along the plume
each day that field work was conducted. The buoy floats were four feet
square, two inches thick polyurthene board which were fiberglassed and
painted orange. The 60-lb. anchors were adequate to hold the floats
in position for the sea conditions encountered during the field work.

Prior to aerial photography the survey boat would set two four-
foot square floats with drogues attached to measure the water currents.
The drogues extended from one half foot below the water surface to five
feet and were constructed of herculite material fitted over a conduit
frame to form a cross banner 4-1/2 ft in length and in width. A ten
pound weight was attached to the lower end of the drogue. The positions
of the current floats were determined from the aerial photography.
The waste concentrations were determined in the plume by boat
sampling. Rhodamine WT dye was metered into the waste discharge pipe-
line on shore with a positive displacement pump. Arrangements were made
with the paper companies to maintain a nearly constant waste discharge
rate while field work was in progress. In addition, they provided the
project with the flow rate records and a dye injection station on the
outfall line near the beach.
12
-------
Dye concentrations in the waste plume were measured with a Turner
III fluorometer aboard the survey boat. The fluorometer was equipped
with a flow through door and continuous readings were recorded with a
chart recorder. The sample was drawn through the instrument with a pump
on the discharge side of the fluorometer. Sample intake ports were
located along the length of a vertical sampling probe mounted on the
side of the boat. By a sliding valve arrangement in the body of the
probe, the sampling depth could be selected from one to ten feet below
the water surface. Details of the sampling probe are given in appendix
B.
An extra fluorometer was always carried aboard the vessel. The
fluorometers were standardized in the laboratory before and after each
run and standardized in the boat offshore from the outfall. Power for
the fluorometer was provided by a 12 volt generator and a 12 volt d.c.
to 115 volt a.c. powercon sine-wave inverter.
While continuous sampling was underway, the fluorometer operator
would mark each position, record position number, indicate any fluoro-
meter scale change and any sampling depth change on the chart record.
The boat's position was determined at one-minute intervals by triangu-
lation. Simultaneous horizontal angles were measured from two shore
stations with Wild T-2 Theodolites. The radio operator aboard the boat
would signal the theodolite operators when the position was to be taken.
A Whitney underwater temperature probe was also carried in the
survey boat. When operating properly, continuous surface water temp-
atures were recorded on a chart recorder.
At the time of boat sampling, aerial photography of the waste dis-
posal area was taken with a six-inch aerial mapping camera and two 70 mm
Hasselblad cameras mounted as a unit in the baggage compartment of a small
high wing aircraft. Normally black and white panchromatic film was used
in the mapping camera, either normal or infrared color film in one Has-
selblad and infrared black and white film in the second Hasselblad.
The nine inch by nine inch pictures from the mapping camera included the
area from below the aircraft to the horizon and were used for photographic
orientation of the smaller cameras. The coverage of the 70 mm pictures
included only the area in the immediate vicinity of the waste field.
The photographic film was developed by project personnel in accord-
ance with the film manufacturer's directions. The aerial film from the
mapping camera was 9-1/2 inches wide and 100 ft long, and was processed
with a Morse B-5 rewind processor while the 70 mm film was processed with
a Nikor reel and tank processor.
A flow diagram for the data processing is shown in Figure 2. The
initial step in processing the fluorometer and temperature records from
the boat survey was to digitize the strip chart records with an X - Y
coordinatograph. The coordinates of the trace were recorded on computer
cards. These cards, along with the cards containing the shore angles,

shifted to account for,the tijne delay for the sample to pass from the
intake port of the sampling probe to the fluorometer. A least square
fit was made to the fluorometer standardization data and the fluorometer
readings were converted to concentration of the tracer. By knowing the
effluent flow rate and the dye injection rate, the tracer concentrations
were converted to effluent concentrations.
Angles from the shore stations to the photo control buoys and
the boat were reduced to state plane coordinates. Since theodolite
sightings were made on the boat's mast, a correction was applied to
determine the position of the fluorometer intake ports. The ground
coordinates for each digitized point on the chart record was interpolated
from the processed shore control data. A detailed description of the
procedure used in digitizing the strip chart records and the computer
program for processing the data are listed in appendix C.
The results of the boat survey were displayed using a three-
dimensional computer plot program. The program draws and labels a state
plane coordinate grid, labels a title on the plot and plots the concentra-
tions or temperature. The axes of the plot are rotated so that the Z-
axis is not perpendicular to the plane of the paper. The waste concen-
tration or water temperature is represented by the length of a line drawn
parallel to the Z-axis. The position of this point can be scaled from
the grid to the base of this line.
Laboratory tests were conducted to determine the effect of the
Kraft waste on the dye traces. Since the presence of the Kraft effluent
in the water does increase the absorption of the exciting and emitted
light in the sample cell, the measurable fluoresence of the tracer will
be reduced by the waste. Using a tracer to effluent ratio of one to a
million, the test showed a reduction of fluoresences of about ten percent
for the range of tracer concentration encountered in the field survey.
Corrections were not made to the field data for the absorption of the
fluoresence by the Kraft waste.
The photographic information was converted to digital data with
a McBeth TD-102 photo densitometer modified for automatic scanning. The
densitometer is equipped with filters and can measure the film densities
of the three layers of a color transparent photograph or the film density
of a black and white negative. The aerial film is placed on the scanning
table. The scanning table is continuously moving and each time the table
changes direction the film is advanced one scan width. The film densities
which are recorded as voltage output from the densitometer and the Y
photographic coordinate are recorded on computer cards at about one-second
intervals while the scanning table is moving. The X photographic coordinate
is computed from the number of scans required to digitize the photograph.
Details of the scanning equipment are shown in appendix D.

By using this method of analysis, the photographic image can be
analyzed and reduced to a symbolic computer image which yields values
of concentration and diffusion coefficients. Details of the reduction of
the photographic information were given in the progress report on Airphoto
Analysis of Ocean Outfall Dispersion (Burgess and James, 1969).

SECTION V
NEWPORT STUDY
The Georgia Pacific pulp and paper plant at Toledo produces about
1000 tons of pulp per day. Following a period of aeration, strong waste
from the process is pumped through an eight-mile pipeline to the outfall
at Newport. Location of the outfall is shown in Figure 3. The waste
disposal area is bounded by Yaquina Head on the north, the north jetty
of the harbor entrance on the south, the shore on the east and a reef
on the west. The reef extends from the west end of the north jetty to
the tip of Yaquina Head. Water depth over the reef varies from about
six feet at the south end to 40 feet at the north end. The topographic
configuration of the waste disposal area influences the circulation
patterns in the receiving water.
The aerial photograph of the Newport-Toledo area shown in Figure
4 was taken looking east with the ocean in the foreground. The location
of the outfall in this figure was sketched on the photo and is shown in
white. The plant at Toledo is located near the upper center of the photo
with the cloud covered Willamette Valley in the background.
Flow rates throught the pipeline vary from about 4000 to 9000 gpm.
Figure 5 is a photograph of the plant looking northeast. The strong
waste from the plant pass through the aeration lagoons shown in this
figure. Holding pond capacity is available for storage of about seven
days effluent from the plant. During periods of unfavorable ocean con-
ditions the ponds hold the effluent. Weak wastes from the plant pass
through the primary treatment plant shown in Figure 5 near the center
of the photograph. Effluent from the primary treatment plant is dis-
charged into the Yaquina River to the left of the bridge.
The 21-inch diameter outfall at Newport was rebuilt and extended
to 3500 ft offshore in 1965. As shown in Figure 6 the outfall terminates
with a wye diffuser in about 40 feet of water at low tide. Thirteen outlet
ports are located at 20-foot intervals on each branch of the wye diffuser.
The ports are three inches in diameter and discharge horizontally into
the sea. They are oriented so that consecutive ports discharge on op-
posite sides of the header. As explained by Baumgartner, James, O'Neal
(1969) the theoretical jet dilution for this outfall design under normal
conditions is about 100. This would represent a waste concentration
by volume of one percent or ten ml/L.
Field work was conducted at Newport during the summers of 1968
and 1969. Table 2 includes a list of dates when sampling was success-
fully conducted. Sampling was attempted on nine days other than those
listed, but work was not accomplished due to rough seas, fog or rain.

Aerial photography .during the 1968 field season was taken with a
single mapping camera mounted vertically. As sunlight reflection on
the water surface was a major problem in processing the data, oblique
photography was used during the 1969 field season. See appendix D for
description of the cameras. A discussion of the results from the various
days of sampling follows.
August 8, 1968
Figure 7 shows the results of the boat sampling on August 8, 1968.
The outfall is located in the upper right and the plume extends southwest
pr to the left. From the appearance of the boat's track which is shown
as a solid line on the plot, it is obvious that the location of the waste
field was not evident from the boat. Maximum concentration over the out-
fall was 15 ml/L. Boat sampling was conducted from 16:06 until 18:09.
The wind was from the NE 10-20 mph with a four-ft swell. The sea surface
was choppy with white caps from the wind; however, no foam from the waste
was observed.
Aerial photography was taken on August 8, 1968 with a mapping
camera mounted vertically using ektachrome 8442 film. The photography
was digitized and processed with the computer. A symbolic plot of the
waste field from the line printer is shown in Figure 8. Each character
on the plot represents a 30 by 30 ft area in the sea. Symbols on this
plot represent different ranges in concentration with the darkest repre-
senting a concentration range of 10-15 ml/L and the lightest representing
a range from 1. to 2.0 ml/L. The plot was made from photos 18 and 19 of
the third flight over the area at 17:30 from 4125 feet. It can be seen
.in Figure 8 that some waste is northeast of the outfall which is located
at the upper tip of the darkest portion of the plot. This is due to a
shift in ocean currents in which the plume extended northward from the
outfall in the morning while in the afternoon the plume extended south-
westward (213° Az). The data shown in Figure 8 was also plotted with a
computerized calcomp plotter using an adapted contour plotting program
which plots iso-concentration lines as contours. This plot is shown in
Figure 7. By comparing the plots in Figures 8 and 9, it can be seen
that the line printer plot is distorted as the longitudinal scale is
greater than the lateral scale. The overall length of the plume was
4600 ft and the width a maximum of 3100 ft. The area within each con-
centration range as determined from photography is listed in Table 3.
The average current velocity in the waste plume was 0.26 ft/sec
and the average steady state diffusion coefficient was 31 ft2/sec. A
discussion of the diffusion computation is given in appendix E.

On August 14, 1968 boat sampling was conducted; however, clouds
prevented aerial photography. Results of the boat sampling, plotted
on the Oregon State plane coordinate grid system (north zone), are
shown in Figure 10. The outfall is located near the high concentration
values at the upper left in the plot and the plume extends northeast
towards the beach. Sampling was conducted from 10:24 to 11:40 when
the wind was 5 to 10 mph from the southwest and the swell height was
4 to 6 feet. It can be seen from figure 10 that the diffusion coefficients
are low as the concentrations 2000 ft northeast of the outfall are about
the same as those directly over the outfall. A light foam streak several
hundred feet long was observed over the outfall while conducting the
boat sampling.

Figure 10. Waste Concentration measured August 14, 1968.
August 16, 1968
On August 16, 1968, the plume was long and narrow and extended
northward from the outfall. The waste field was 600 to 1200 ft wide
and about 7000 feet long. Photography was taken with a vertical mapping
camera using ektachrome type 8442 film. Symbolic plots of the waste
field made from photos 3 and 4 of flight one from 8400 ft and from photos
17, 18 and 19 of flight three from 4200 ft are shown in Figure 11. The
plot in Figure 12 was made by subtracting the concentrations of the left
plume in Figure 11 from those shown in the right plume. Areas where
the concentration difference exceeds six units have been cross hatched.
The mean concentration difference in comparing 2485 points inside the
plume of either flight was 1.8 units. From the outline of the plume it
can be seen that plume changed considerably during the 22-minutes
between flights. The data shown on the left of Figure 11 was plotted
with the contour plot program and is shown in Figure 13.
Areas of different waste concentration ranges within the plume
are listed in Table 4. These values were computed from flight three.
The average current velocity was 0.42 ft/sec with a mean diffusion
coefficient of two ft2/sec. The photo of the plume over the outfall
shown in Figure 14 was made from photo three of flight one with a red filter.
It can be seen that the addition of 17 cfs of effluent to the receiving
water moving at 0.42 ft/sec did not cause appreciable spreading of the
26
-------
plume; whereas, on August 8 the addition of 12.4 cfs of effluent to the
receiving water moving at 0.26 ft/sec did cause spreading of the plume
and the plume was half-moon shaped.
The wind of 10 to 15 mph from the southwest was not sufficient
to create a choppy water surface. A large swell of six to eight ft did
not contribute much to the diffusion of the waste.

August 21, 1968
On the morning of August 21, 1968 the swell was ten feet and
breaking on the reef offshore from the outfall. Boat sampling was
delayed until the afternoon. The wind was zero to five mph from the
southwest, but by mid afternoon had changed to 10 to 15 mph from the
northwest. The boat sampling was conducted from 12:10 until 13:41 and
is shown in Figure 16. The outfall is located in the lower left of the
plot and the plume extends northward. The plume was approximately
30
-------
7500 ft long, 800 ft wide near the outfall and 2000 ft wide at the end
of the plume. Maximum concentration over the outfall was 20 ml/L.
Vertical aerial photography was taken using Ansco D-200 film.
As this was the photographic firm's first experience with the film,
the film was under exposed about one stop. This combined with scattered
clouds rendered the photographic results of questionable value.

September 10, 1968
On September 10, dye slugs were introduced into the pipeline.
Because of density stratification, the waste field and dye slugs were
submerged. There was no wind on this day and the swell height was one
to two ft. The dye slugs did not move away from the outfall in discrete
patches as planned but accumulated about the outfall area below the water
surface. The boat sampling showed measurable dye concentrations only
directly over the outfall.
Aerial photography was taken using Ansco D-200 film. A copy of
one of the vertical photos over the outfall is shown in Figure 17. It
can be seen that there was considerable foaming of the effluent. The
photograph is oriented so that north is to the right and the outfall is
located near the upper center of the photo. Foam extends both west then
north and northeast from the outfall. The submerged plume can be seen
in the photo where not obstructed by the foam as the light area to the
south and east of the outfall. This photo covers an area 3400 by 4600 ft.

September 11, 1968
The weather conditions were about the same as on the 10th except
that clouds covered the area and there was a 0-5 mph east wind. The
plume was still submerged but the individual boils over the outfall
could be seen from the boat. Two foam streaks extended westward from
the outfall for about a half mile. Dye slugs were injected into the
pipeline; however, dye concentrations were only detectable directly
over the outfall.
September 12, 1968
Weather conditions remained calm until about 2 p.m. when a
15-20 mph wind from the northwest began. The plume was submerged in
the morning but came to the surface after the wind began blowing.
Waste concentrations measured by boat sampling from 15:49 until 17:11
are shown on the Oregon State plane coordinate (north zone) grid in
Figure 18.
The outfall is located near the center of the plot and the plume
extends southward. Maximum concentration over the outfall was about
10 ml/L. Detectable concentration were measured 3000 ft from the outfall.
Vertical aerial photography was taken of the plume using a 6-inch
focal length camera. The interference caused by sunlight reflection on
the choppy water surface made the photography impossible to process.

June 50 and July 1, 1969
On June 30 and July 1 the plume was submerged below the sea sur-
face. There was a light breeze of about five mph from the east in the
morning shifting to 5-10 mph from the north in the afternoon with a one
to two ft swell on June 30th. Aerial photography was taken of the outfall
area but there was no evidence of the waste field from either the photo-
graphy or the boat sampling.
The weather remained calm with a two to four ft swell on July 1st.
The photo of the outfall area shown in Figure 19 was taken from 600 ft
with the camera oriented 45 degrees from vertical towards the west. Four
buoys can be seen about the outfall but all that is visible of the waste
field is a small amount of surface foam which covers an area approximately
200 by 300 ft. The sky was overcast and surface light reflection can be
seen in the upper part of the photograph.
Figure 19. Aerial photo of the outfall area on July 1, 1969.
-------
July 7 and 8, 1969
On both days the wind was from the north and a foam streak
extended southward from the outfall for approximately 1.3 miles. On
July 7th the surface plume was narrow and extended only a few hundred
feet from the outfall. The wind on the 7th increased from 5 mph at 8:00
to 12 mph at 20:00.
The infrared black and white photos in Figure 20 show the foam
on July 7th. Infrared photography does not indicate temperature differ-
ences. The photo in Figure 20A was taken in a northwest direction with
the shore in the foreground and the foam extending southward from the
outfall. The photo in Figure 20B was taken over the outfall in a west-
ward direction with the foam streak extending upwards and to the left.
The survey vessel was crossing over the outfall in Figure 20B.
Figure 20. Photographs of the foam on July 7, 1969.
On July 8th the wind was stronger and increased from 6 mph at
8:00 a.m. to 15 mph at 15:00. Photos in Figures 21 and 22 show the
plume on July 8 at 15:21 and 15:56. The photos were taken from 4000 ft
with the camera tilted 45 degrees from vertical towards the east. A
foam streak can be observed extending from the outfall on the left.
The foam and the plume do not coincide as the plume is to the right of
36
-------
the foam. In Figure 22 dark- upwelled water can be seen below (west)
the plume. Measurements from the temperature probe indicated that this
water was approximately two degrees C warmer than the inshore water.
The upwelled water appears to move over the plume with limited mixing
between the two masses. The upper or nearshore edge of the plume did
not change position between photos.
Results of the boat sampling are shown in Figure 23. The outfall
is located near the center of the grid and the plume extends southward
or towards the left. The sampling was conducted from 15:00 until 16:16
and the maximum concentration measured over the outfall was 10 ml/L.
Three photographic flights over the outfall were processed.
Ektachrome type 8442 film was used in the mapping camera while the two
70 mm cameras were used with infrared color type 8443 and infrared black
and white type 5424. Symbolic plots for the three flights are shown in
Figure 24. In order to have the longitudinal and lateral scales approx-
imately equal, each symbol on the remaining symbolic plots in this report
represent an area of 20 ft across the plume and 30 ft along the plume.
The plots shown in Figure 24 were from flights taken at times 15:15,
15:21 and 15:56 and from 3000, 4000 and 4000 ft, respectively. They
include only the first 2300 ft of the plume so that the change in plume
shape between flights can be seen. Measurable concentrations extended
5500 ft from the outfall.
The average steady state diffusion coefficient for flights one
and two was 14 ft^/sec while the average diffusion coefficient from
flight three was 9 ft2/sec. The average current velocity was 0.5 ft/sec.
Area within the different concentration ranges as computed from flight
three are listed in Table 5.

August 12, 1969
Both aerial photography and boat sampling were successfully
conducted on August 12, 1969. Waste concentrations determined from boat
sampling from 12:44 until 13:46 are shown in Figure 25. The outfall is
located near the center of the grid and the plume extends northwest or
upward and to the right.
Surface water temperatures measured from the boat are shown in
Figure 26. The height of a vertical line on the plot represents the
water temperature in degrees C. minus nine degrees. This method of
plotting was used so that a small difference in water temperature would
be apparent as it is easier to see a difference in lengths of lines that
are one and two units long than lines that are ten and eleven units long.
It can be seen in the plot that the water temperature over the outfall
was about two degrees colder than in the upper right of the plot where
the waste concentration is zero. Although the effluent in the pipeline
is about 40°C. it mixes with the subsurface water and the resulting mix-
ture on the surface in this example was colder than the surrounding sur-
face water.
The oblique photo of the plume shown in Figure 27 was taken with
the camera pointed northward from 4,000 ft. In the immediate vicinity
of the outfall the foam extends both east and west of the outfall then
northward. This foam pattern is similar to that on September 10, 1968.
The waste field extends in all directions from the outfall but primarily
northwest. The wind was three mph from the east in the morning but changed
to five mph from the west in the afternoon.
One current float set to the west of the outfall moved northwest
while the other current float set to the east of the outfall moved north-
east. The average current velocity was 0.1 ft/sec. It appears that
under these relatively calm conditions, that the hydraulic head created
by the effluent has a measurable influence on the shape of the waste field.
A symbolic plot of the waste field is shown in Figure 28. While
three flights were processed, the photographic results were essentially
the same in each case. The hole or blank area in the plume was in the
foam over the outfall where concentrations could not be computed. The
plot shows a large waste field with nearly uniform concentration of 6
to 10 ml/L throughout. The azimuth from north of the centerline of the
plot in Figure 27 is 340°. Area within the different concentration
ranges are listed in Table 6.

The photograph of the plume shown in Figure 29 was taken from
8,000 ft looking north. The surface plume was small and extended
northward from the outfall. A small amount of surface foam can be seen
about the outfall. The location of the plume was not obvious from the
boat while sampling; however, a large subsurface plume could be seen
from the aircraft extending northeast from the outfall. The wind was
from the southwest at 5 mph with a four-foot swell.
Data for the symbolic plot of the waste field, shown in Figure
30 was from the 70 mm infrared color photography taken from 3,000 ft.
The current velocity was 0.2 ft/sec. Area within the different concen-
tration ranges are listed in Table 7. Results of the boat sampling are
shown in Figure 31.

SECTION VI
GARDINER STUDY
The International Paper Plant at Gardiner produces approximately
550 tons per day of pulp and discharges about 10,000 gpm of liquid waste
into the ocean. The ocean outfall is located 5-1/2 miles north of the
mouth of the Umpqua River. A straight shoreline extends both north and
south of the outfall and the shore near the outfall is a gently sloping
sandy beach. The location of the outfall is shown in Figure 32. The
plant is located about a mile north of Gardiner and discharges its wastes
through a three-mile pipeline to the ocean.
The photograph in Figure 33 was taken looking northeast. The
location of the outfall was sketched on the photo and is shown in white.
It can be seen that there is no residential development on the shore near
the outfall. During low tides, three to six vehicles were parked near
the beach on the access road to the outfall while the occupants were
digging clams. The plant is located near the bend in the Umpqua River
to the right of the picture. Dark upwelled water can be seen in the
lower left of the photograph.
A photo of the International Paper Plant is shown in Figure 34.
Liquid waste from the process are discharged into the pond shown on the
left of the figure. A pumping station located to the left of the pond
pumps the waste over the hills to the ocean. The 36-inch outfall extends
about 3,000 feet offshore and terminates in about 25 ft of water. As
shown in Figure 35, the diffuser section consists of 24 five-inch diameter
ports spaced 7.5 ft apart. The ports are oriented horizontally and
alternately discharge on opposite sides of the pipeline. Shifting sands
partially cover the diffuser section and it was not known how many of the
ports were open at the time of sampling.
Boat sampling was conducted with the charter boat "Sea Hawk" from
Winchester Bay on July 15 and 16, and August 19 and 20, 1969. In addition
the Northwest Regional Office and the Pacific Northwest Water Laboratory
of the Federal Water Quality Administration conducted a survey of the
outfall during the week of January 20, 1969. Measurements of a dye tracer
released during the survey produced a minimum dilution of 1:27 over the
outfall. An extension of the centerline of the plume during this study
would have intersected the beach approximately one mile south of the outfall.
In addition, a biological survey conducted during the study showed that
more organisms and more species were observed over the outfall than at
other surrounding locations. Description of the sampling by dates follow.
July 15 and 16, 1969
On July 15 and 16 the wind was 10 to 18 mph from the NNW during
the sampling period. The swell on the 15th was four ft, and two to three
ft on the 16th.

Air bubbles in the fluorometer intake lines rendered the results
of the boat sampling of little value on July 15. The plume configurations
were similar on both days and the results of the boat sampling on July 16
are shown in Figures 36 and 37. The first sampling run shown in Figure 36
was conducted from 12:39 until 13:35 while the second run shown in Figure
37 was conducted from 14:45 until 15:36. The plume extended southward
(left) from the outfall with a maximum concentration of 23 ml/L over the
outfall.
While the survey boat was headed westward, direct sunlight was on
the instrument. Since the sunlight caused interference with the fluoro-
meter readings, these sections of the sampling record were not processed
and discontinuous boat track is shown in Figures 36 and 37.
Aerial views of the plume are shown in Figures 38A and 38B. The
photos which were taken at 15:05 are 45 degree oblique views from 4000
ft. The outfall in Figure 38A is located at the center of the photograph
and the plume extends to the right. One area of relatively high waste
concentration extends south from the outfall while a second area of high
concentration extends southwestward. The dye patch located near the
lower left of center on 38A was dropped at 14:20. The dye patch shown
in lower right of Figure 38B was dropped at 12:14. The plume in Figure
38B is shown in the upper left of the photo.
Three photographic flights over the outfall area were processed.
The iso-concentration plot shown in Figure 39 was from the first flight
over the outfall at 14:50. The concentration interval on this plot is
2 ml/L with the outside contour representing 2 ml/L. The symbolic plot
of the waste field shown in Figure 40 was made from the second flight
over the area from 5000 ft at 15:03. Infrared color film and infrared
black and white film were processed from the 70 mm cameras. The large
mapping camera was used for orientation and current float position
computations.
The plume on July 16, 1969, is similar to that for August 8, 1968,
at Newport. It appears that the addition of 22.4 cfs of waste to the
receiving water moving at 0.26 ft/sec caused surface spreading of the
plume near the outfall. Two current floats were set above the outfall.
One float moved downstream in the waste field but the second float set
on the centerline of the plume remained stationary just upstream from
the outfall. Since there was no kelp in the area, to hold the float,
it may have been set at the stagnation point created by a source in a
uniformly flowing stream.
The average steady state diffusion coefficient was 9 ft2/sec.
Areas within the different ranges in waste concentration as determined
from flight 2, are listed in Table 8.

August 19 and 20, 1969
The swell height was four to five feet on both sampling days with
a light wind of zero to five mph from the west. The fog did not lift
until noon on the 19th but was clear at 11 o'clock the next day.
Waste concentrations determined from the boat samplings are shown
in Figures 41 through 43. Maximum concentration over the outfall was
22 ml/L. The boat sampling shown in Figure 41 was conducted from 15:16
until 15:39 on August 19, 1969. The sampling period was short because
of generator trouble and the plume in Figure 41 is not well defined. On
August 20 the first sampling period was from 11:33 until 12:04 and the
second sampling period was from 15:05 until 15:34.
Surface water temperature measured during the two sampling periods
on August 20 are shown in Figures 44 and 45. In general the water temp-
erature over the outfall was one to two degrees colder than the surrounding
water temperature.
The plume changed shape and location while sampling on both
August 19th and 20th. Low tide on the 19th was at 10': 20 and high tide
was at 16:50. The oblique view of the plume in Figure 46 was taken from

4000 ft at 12:39, August 19, using panchromatic black and white film with
a 25A filter. The outfall is located in the lower right and the plume
extends upward to the left along the surf zone. A tide rip can be seen
extending through the surf zone in the upper left and a dye patch can be
seen offshore from the plume on the left.
The two 70 mm photos in Figure 47 were taken in the same flight
with infrared black and white film with an 89B filter. The boat in
Figure 47A appears as a white spot in the center of the picture. Infrared
photography of the plume requires about three stops more exposure than
land detail. The dye patch in Figure 47A is just visible on the IR film.
As the photos were scanned automatically, the infrared band was used to
distinguish the dye from the waste field in the computer processing.
Figure 47B was taken over the outfall.
The variation in film density in the infrared photograph is greater
than that in Figure 46. Ninety percent of the light return in the infrared
band is from the upper two feet of the water; whereas, in the red band
ninety percent of the light return is from the upper seven feet.
The photos of the plume in Figures 48 and 49 were taken at 13:53
from 6000 ft and at 16:28 from 4000 ft, respectively. The plume in
Figure 48 extends upward and to the left from the outfall located near
the lower right of the photo. The dye patch can be seen as a narrow
streak oriented approximately perpendicular to the beach at the left of
Figure 48. At 16:28 the plume extended directly towards shore from the
outfall.
The 70 mm color photo of the waste field in Figure 50 was taken
at the same time as that shown in Figure 49. The variation in grey on
the print represents the change in blue film density of the original
transparency. The surf is visible in the upper right as the dark area.
Near the upper center of the photo is gray area which is suspended sand
from the turbulent surf zone and relatively free of waste. The differen-
tiation between the plume and the suspended sand is not possible in
Figure 49 which was taken with panchromatic film and a red filter. The
blue band was useful distinguishing the suspended sand from the plume
in the processing of the photographic data.
On the morning of August 20th the waste plume extended from the
outfall northeast into the surf. The photos of the plume shown in
Figures 51 and 52 were taken at 11:27 from 4000 ft and 11:41 from 5000 ft,
respectively. The survey boat can be seen sampling the waste field. The
outfall is located about a half inch below the boat in Figure 52. The
shape of the plume about the outfall is mainly a result of surface
spreading of the waste caused by a 17 cfs source in a relatively calm
receiving body. Apparently the water currents carry the waste north-
eastward from the outfall and the swell is moving the waste into the
surf. Swell normally does not have a large forward transport; however,
in the nearshore area when the wave peaks, the swell begins to change
from an Airy or Stokes wave to a solitary wave with a forward transport

of water near the surface. The dye patch shown in the lower left of
Figures 51 and 52 was dropped at 11:03. It can be observed that the
dye patch moved northeast towards the outfall several hundred feet bet-
ween flights. The current velocity was 0.13 ft/sec. Infrared black
and white photos of the waste field are shown in Figure 53. The photo
in Figure 53A was taken at 11:27 from 4000 ft while the photo in Figure
53B was taken from 8000 ft at 12:15. The boat is the white spot in
Figure 53A and the surf is on the right. The three white dots to the
left of the plume in Figure 53B are salmon fishing boats.
At 14:30 it appeared that the waste discharge into the ocean had
stopped. However, a few minutes later a very dark brownish-red effluent
began appearing on the surface. This may have been caused by a sluge
deposit slumping into the pump sump in the holding pond. The photograph
in Figure 54 was taken at 15:45 from 4000 ft. The new plume can be
seen extending from the outfall northward. The old plume has dispersed
but some of the waste can be seen north and south of the outfall. A tide
rip near the center of the photo extends from the surf. This area appears
as light gray and is bounded by a small foam streak. The water in the
rip is nearly free of waste but in the red band is not distinguishable
from the surrounding water containing waste.
A symbolic plot of the waste field for flight three taken at 16:30
on August 19, 1969 is shown in Figure 55. The plot is oriented so that
the axis of the plume is at an azimuth of 110 degrees from north. The
plot shows nearly uniform concentrations throughout the waste field. Table
9 shows various concentrations and the areas encompassed.

SECTION VII
SAMOA STUDY
The Georgia Pacific Corporation plant of Samoa, California is
located on a narrow sand spit one mile west of Eureka as shown in Figure
57. The sand spit is about eight miles long, one mile wide and is bounded
on the east by Arcata Bay and on the west by the Pacific Ocean. The
Georgia Pacific plant is located approximately four miles north of the
entrance to the bay.
Crown-Simpson Company has a plant at Fairhaven which is located
on the spit approximately 2-1/2 miles north of the bay entrance. Both
plants discharge their liquid wastes into the ocean. During the study
period of August 6 and 7, 1969, the Crown-Simpson plant was not in oper-
ation. However, they were pumping water from the bay through their outfall
in order to prevent sand from covering and plugging the diffuser ports.
The Georgia Pacific plant produces about 500 tons per day of bleached
pulp. Liquid waste from the process is discharged through a 48-inch
outfall into the ocean. A photograph of the plant is shown in Figure 58.
The location of the outfall was sketched on the photograph and is shown
as a white line. The outfall extends about 2900 ft into the ocean and
terminates in about 40 ft of water. As shown in Figure 59, the diffuser
section contains 50 ports spaced ten ft apart. The eight-inch diameter
nozzles discharge horizontally and are pointed to alternately discharge
on opposite sides of the header. Due to drifting sand, it is not known
how many of the nozzles were operating at the time of sampling.
Field work was conducted at Samoa on August 6 and 7, 1969. The
Humbolt State College research vessel "Sea Gull" was chartered for the
boat work. The swell was three to four feet on these two days and the
wind 5-10 mph from the northwest. Fog on both days prevented sampling
in the morning.
Waste concentrations determined by boat sampling are shown in
Figures 60 through 63. Sampling on August 6 was conducted from 14:21
until 15:01 for run 1 and from 15:59 until 16:49 for run 2. On August 7
the boat sampling was conducted from 12:53 until 14:39 and from 16:00
until 16:26 for runs 1 and 2, respectively.
The outfall is located on the right of the plots and the waste
plume extends towards the left or southwest. The state plane coordinate
grid was drawn at 800 foot intervals. The plume is bounded on the south-
east by the surf zone. Maximum concentrations measured over the outfall
were 18 ml/L or a 1.8 percent waste concentration by volume. The effluent
flow rates were 18,600 and 16,500 gpm on the two sampling days.

Surface water temperatures minus 10°C. as measured on August 6
and 7 are shown in Figures 64 and 65. It can be seen that there was
little temperature variation in the surface water and that the offshore
water tended to be slightly warmer than those in the plume or nearshore.
The lowest temperature value was located at the south end (left) of the
boats track shown in Figure 65. This point was in Crown-Simpson's fresh
water plume.
On the aerial photograph of the plume shown in Figure 66, the
outline of the Georgia Pacific plume is shown with the broken line while
the outline of the Crown-Simpson plume is shown with a solid line. The
photo was -taken from 5000 ft at 17:09 on August 6, 1969. During the two
days of field observations the plume maintained nearly the same size,
shape and position. Although, at times the entire plume moved between
the shore and the Crown-Simpson plume. The plume was 700 to 1500 ft
wide and about 8000 ft long.
A symbolic plot of the waste field is shown in Figure 67. The
plot was made from flight one on August 6th. The flight was taken from
3000 ft at 17:27 o'clock. As the first two 70 mm photos did not overlap
a blank area is seen near the head of the plume. The total area covered
by the plume was 155 acres.
Problems were encountered in the photographic data from Samoa on
August 7th. The processing of the photographic data requires that the
background light from the open sea be subtracted from the light return
in the plume. Because the plume extended to the surf zone, background
light measurements were available from only the offshore side of the
plume. The large variation in the color of the water perpendicular to
the shore rendered the photographic results of questionable value.
The mosaic strip in Figure 68 shows the plume at 16:20 on August 7th.
The negative prints were made from 70 mm infrared color photographs
from 6000 ft. The dark area in the upper part of the strip is caused by
suspended sands near the surf zone. The Georgia Pacific plume extending
from left to right in the mosaic is almost entirely inshore of the Crown-
Simpson plume shown near the right of the figure. Numerous fishing boats
can be seen about the outfall area. The light area in the lower portion
of the negative prints is caused by dark upwelled water. A dark narrow
band can be seen along the lower (west) edge of the plume.

SECTION VIII
SUMMARY
During the period of August 1968 through September 1969 field
work was conducted on thirteen days at Newport, four days at Gardiner,
and two days at Samoa. A summary of the sampling is shown in Table 11.
Observations were conducted at Gardiner on July 15-16, 1969 and
August 19-20, 1969. As the sea and weather conditions were similar on
consecutive sampling days, the results represent essentially only two
independent observations. In the first sampling period, the waste moved
away from the beach while during the second sampling period the plume
extended into the surf zone. It is believed that there is a greater
tendency for the waste field to extend into the surf at Gardiner than at
Newport, because of its shorter and shallower outfall and greater flow
rates, however, it is not known what percent of the time this occurs.
Maximum concentration measured over the outfall was 23 ml/L or 2.3%.
Observations were conducted at Samoa on August 6-7, 1969 when
the wind was from the northwest. A large plume extended south along
the surf zone. Maximum concentration measured over the outfall was
18 ml/L.
Surface water temperature measurements were made at the three
outfall locations. Since the warm effluent from the diffuser ports mixes
with the cold subsurface water, the resulting mixture at the surface was
generally colder than the surrounding sea water. Because of natural
temperature variations in the sea water, temperature is not a sensitive
tracer for tracking the waste field.
It can be seen from the table that during relatively calm periods
the plume at Newport was submerged. On September 10, 11, and the morning
of the 12, 1968, the plume formed below the sea surface. On the after-
noon of the 12th the wind increased to 20 mph, white caps formed and
the plume came to the surface. On June 30 and July 1, 1969, the plume
was also submerged. Hourly wind records at the south jetty show that on
June 30th, the wind was five mph in the morning, increased to about ten
mph at noon, and remained at this level throughout the night. A surface
plume may have formed during the night but during the day of July 1st
the wind was 4-5 mph and the plume was submerged. On July 7, 1969, the
hourly wind pattern was similar to that of July 8, 1969, except on the
second day the wind was about three mph higher. On July 7th a surface
plume could be seen only for a short distance from the outfall, while on
the 8th the plume was on the surface.
The weather was calm on August 12, 1969, with a wind of 3-5 mph.
Wind records show that the llth was also calm yet a large surface waste
field was observed on the 12th. The effluent discharge rate was nearly

the same on this day as it was on the days when the plume was submerged
under nearly similar conditions. Possibly the offshore thermocline was
deep and the dense subsurface water was not available to form density
stratification in the outfall area.
Observations were made at Newport when the river flow was low.
During the winter and spring when the wind is predominately from the
southwest and the fresh water flow from the Yaquina River is high, there
may be an increased tendency for density stratification to form over the
outfall. There is also indication that the tidal range affects the density
stratification and area of the surface plume, but sufficient observations
for verification are not available.1
Subsurface plumes are believed less likely to occur at Gardiner
and Samoa since they are located on the open coast. Newport outfall has
the offshore reef which would tend to reduce the turbulence and mixing
below the level of the reef.
The most foam was observed on September 10, 1968 and August 12,
1969. Both days were calm with a submerged plume on September 10 and a
surface plume on August 12. On September 11, 1968, July 7 and July 8, 1969,
and September 8, 1969, foam was observed. Except for July 8th, when the
sea surface was choppy, these days were relatively calm. The foaming
tendency may also be caused by a change in the composition of the waste.
The primary source of foam did not appear to be caused by wind turbulence
in the waste field, but rather the foam appeared to be mainly generated
in the boil over the outfall.
When the current velocity is low in the receiving water, the
initial width of the plume is greater than the width of the diffuser section
of the outfall. On August 16, 1968 and July 8, 1969 at Newport and August
6 and 7, 1969 at Samoa, the current velocity was greater than 0.4 ft/sec
and the initial plume width was about the same as the diffuser section of
the outfall. On August 8, 1968 at Newport and July 16, 1969 at Gardiner,
the current velocity was 0.26 ft/sec and the initial width of the plume
was wider than the diffuser section with a ridge of high waste concentration
near the outer edge of the plume. At current velocities less than about
0.2 ft/sec surface spreading caused by the hydraulic head from the effluent
discharge appeared to be primarily responsible for the width of the plume.
Diffusion coefficients are listed in Table 11 for only three days, since
the model used in the diffusion computations and explained in Appendix E,
would only be applicable to these situations.
The tide influences the flow patterns in the receiving water.
The high flood and ebb currents at the river mouth tend to draw water from
the adjacent ocean. Since the outfalls observed in this study were located
several miles north of a river mouth, the effect of the tide was reduced
and the wind generally provided the major driving force for water movement.

-------
The area of the waste field listed in Table 11 is the area where
the concentrations were computed from the aerial photography as being
greater than 2 ml/L or 0.2% waste. Normally from the photography, the
plume can be distinguished from the open sea at concentrations greater
than 0.4 ml/L. However, surface foam on July 8, August 12, and September
9 caused interference with the aerial photography. In the processing of
the data, voltage ranges on the photo densitometer output were set and
concentrations were not determined for points where the densitometer
voltage was outside this range. Values for these points were obtained
by interpolating from adjacent points. The infrared band was the most
sensitive for this purpose. The area covered by the densitometer aperture
could contain a small amount of surface foam and the value would not be
rejected. Some scatter can be seen along the right side of the plumes
shown on the symbolic plots in Figure 24 where there was a foam streak as
can be seen from the photos of the plume in Figures 21 and 22. A summary
of the aerial photography is listed in appendix F.

SHORE CONTROL
Control surveys were conducted at Newport, Oregon, Gardiner,
Oregon and Samoa, California. These surveys provided control for both
the aerial photograph and the boat sampling. Figure A-l shows the location
of the beach traverse at Newport. The traverse extended between two coast
and geodetic survey stations, Life on the south and Yaquina Head Lighthouse
on the north. Angles along the seven-mile traverse were measured with a
Wild T-3 theodolite while the distances were measured with the telurometer.
The unadjusted state plane coordinates are listed in Table A-l. A closure
of 1:21,000 shows the excellent quality of the survey work.

The established stations were marked with cloth for photo ident-
ification. A typical shore control station while boat sampling was in
progress is shown in Figure A-2. The tripod signal in the foreground was
used to sight the station from the boat. For some of the preliminary
survey work at Newport, the boats position was determined by three-point
sextant fixes from the vessel. However, because of difficulty in training
the crew, this method of boat positioning was replaced by shore triangulation.

The survey near Gardiner was conducted between two Oregon State
Highway stations. The location of this survey is shown in Figure A-3.
Coast and geodetic survey stations are in the vicinity of the outfall but
since this is a sand dune area the station markers were not found. Results
of the survey are tabulated in Table A-2.

FLUOROMETER SAMPLING PROBE
During the 1968 field season tracer concentrations were measured
in the waste field using two continuous flow fluorometers as shown in
Figure B-l. In take ports for the instruments were along the leading edge
of the five-foot keel of a six-foot long towed vessel. The vessel was
constructed of fiber-glassed floatation foam and was towed eight feet off
the beam of the survey boat. By a valve arrangement aboard the survey
launch, the sampling depth for one fluorometer could be selected at either
one-half foot or one foot below the water surface and the sampling depth
for the other fluorometer was either at two feet or five feet below the
surface. The fluorometer readings were continuously recorded by chart re-
corders. Generally the sampling depths were at one foot and five feet.
A comparison of concentrations at these two sampling depths did not show
any appreciable difference and indicated that the sampling device was
inadequate' to reach the lower limits of the waste plume.
A ten-foot sampling probe was constructed for the 1969 field
season. This probe is shown mounted aboard the Humbolt State College
research vessel Sea Gull in Figure B-2. The probe is attached on the
starboard rail and the end of the probe is setting on the aft deck in a
travelling position; The probe was designed to hang vertically at five
knots. As it has a mechanical feed-back steering device, it is stable
at higher speeds and through normal maneuvers. Drawings of the probe
are shown in Figure B-3 through B-7.

APPENDIX C
REDUCTION OF BOAT SAMPLING DATA
Included in this appendix is the program listing of the computer
program used to reduce the temperature and fluorometer data from the boat
survey along with the instructions necessary for digitizing the strip chart
records. The program was written for the CDC 3300 system in fortran IV
language.
InpUt data f°r the Pr°gram is either from a logical unit number
(LUN) or from the teletype keyboard. The input statements include stand-
ard READ statement, FFIN(NO), TTYIN (4H X = ). The free form input (FFIN)
will accept data in any format from columns 1 through 72 as long as the
words are separated by at least one space. The number in parentheses with
the call command is the input LUN number. The teletype free form input
command (TTYIN) allows the user to enter data from the teletype. The
parameter in the TTYIN function is hollerith constant containing four char-
acters. When the fortran statement is executed, the hollerith message
is printed on the users teletype. Only a single variable can be entered
each time the function is executed.
The main program called Boatdata (lines 1-82 of the listing) calls
subroutines Readcord, Bcontrol and Concen. Subroutine Readcord (lines
83-196) converts the digitized strip chart data on LUN 1 to chart readings
and writes the readings on LUN 2 according to the format listed on line
188. Subroutine Bcontrol (lines 188-313) reads from LUN 3 the angle and
distance from the boat's mast to the sample intake ports (lines 203-204)
coordinates of the shore station (lines 206-209), and the shore angles to
the boat, buoys, or initial angles according to the code listed on lines
224-225. The subroutine writes the coordinates of the sample probe on
LUN 4 along with the fix number and other positions (fixed sampling station,
buoys, floats) on LUN 20.
Before the main program calls subroutine Concen, it reads from
the teletype values of the effluent flow rate, dye injection ratio, time
delay for sample to reach the instrument and data code as shown on lines
43-50. Subroutine Concen (lines 314-359) calls subroutine Fluoro if a
fluorometer record is being processed, reads the chart readings from LUN 2
and computes either waste concentration in mi Hiliters per liter, dye
concentration in parts per billion or the water temperature depending on
the value of the branching code as explained on line 47 of the main program.
Output from the subroutine is written on LUN 6 according to the format
list on line 351.
\
Subroutine Fluoro reads the fluorometer standardization data as
explained by the comments in lines 371-381 of the listing and calls sub-
routine Leastfit which determines the least square estimate for the para-
meters in the model.
121
-------
Y = BQ + B X + B2 X2
or in matrix notation
Y = X B (2)
where Y is the dye concentration in PPB, X is the scale reading and
the B's are the coefficients. Solution to equation 2 is
B = (X'X)"1 Y (3)
Subroutine Leastfit (lines 400-442) computes the X'X matrix, calls
Matinv (lines 443-510) which computes (X'X)-l and then computes the B
vector as shown in equation 3. Once the values of the parameters are
estimated in equation 1, the concentrations can be computed in line 345
of subroutine Concen.
The main program then reads the fix numbers and concentrations
or temperature from LUN 6, determines the coordinates of the sampling
point from the data on LUN 4 and writes the coordinates and concentration
or temperature on LUN 8 (lines 55-80).
Considerable savings in time resulted from digitizing the strip
chart records with the coordinatograph rather than by hand scaling and
coding. The following procedure was used to reduce the fluorometer and
surface water temperature chart records to digital data.
The Rustrak strip chart was taped to the Kelsh plotter table with
the longitudinal axis of the chart being approximately straight and
approximately parallel to the X-axis. The X coordinate increasing with
time and the Y coordinate increasing with the chart reading. The X and Y
coordinates were measured with the Autotrol coordinatograph and punched
on computer cards. First, the chart's longitudinal and transverse scales
were digitized for calibration of the curve readings, next, the coordinates
of the trace were recorded.
Each card contained constant data and three sets of event numbers,
X,Y, § Z coordinates. The constant data in the first five columns was
as follows:
Column 1 Month (one digit)
Columns 2 $ 3 Day (two digits)
Column 4 Run number (either 1 or 2 )
Column 5 Codes 1-4 Fluorometer
5-8 Temperature
122
-------
CODE
1 or 5 The X and Y coordinates are measured on the chart's
zero reading at each consecutive fix (marked or unmarked).
The event number is equal to the fix number. This infor-
mation is used to interpolate the fix number and the zero
scale when computing the readings.
2 or 6 The X and Y coordinates are measured at the chart's
0, 10, 20, 30, , 100 for the first fix number.
The event number times ten is equal to the scale reading
for the fluorometer trace and the event number times a
half for the temperature trace as full scale is five
degrees.
4 or 8 X .and Y coordinates were measured along the trace at
intervals as required to define the curve but not greater
than one inch. For the fluorometer record, the first
two digits of the Z coordinate represent the scale (1,
3, 10, or 30) while the last two digits of the Z coor-
dinate represent the sampling depth. When reducing the
temperature record, the first two digits of the Z
represent the zero scale temperature (0,5, 10, 15, or
20°C). As the temperature probe was always one foot
below the water surface, the depth was not indicated on
the Z coordinate.
The event number is significant only when tracing about the chart
for calibration (when the code in column five is one, two, or three for
a fluorometer trace or five, six or seven for the temperature trace). The
scale and sample depth need to be listed only when tracing the curve (code
is either four or eight). Each card includes the constant data, event
numbers, X § Y coordinates, scale and depth for up to three points according
to the format listed on line 102 of the program listing.

APPENDIX D
PHOTOGRAPHIC EQUIPMENT
1Q6« flnH ?QAQ J S reP°rt are PhotoSraPhic data taken during the
1968 and 1969 field season. Aerial photography was taken the first year
by a commerical aerial photography firm using a precise mapping camera
mounted vertically. As the firm was located approximately 100 miles from
the study area scheduling the photography was difficult. Several times
clouds moved over the work area during the time it took the aircraft to
reach the outfall site. In addition sunlight reflection from the water
surface created serious problems with the processing of the vertical
photography even though it was taken when the sun altitude was between
30 and 35 degrees.
During the 1969 field season the photography was taken with two
70 mm Hasselblads and a K-17 mapping camera. These cameras are shown
in Figure D-l and were mounted obliquely to avoid the sunlight reflection
from the water surface. The cameras were mounted in the baggage compart-
ment of a rented aircraft and pictures were taken through the baggage
compartment opening. The door of the compartment was removed while the
cameras were mounted.
The camera shutters were synchronized with the timing delay device
shown in Figure D-2. The cameras were lined up end to end without their
magazines. The variable resistor shown in Figure D-2 was adjusted until
a light could be seen through the cameras when the shutters were actuated
at 1/100 of a second.
The aerial photography is digitized in the photogrammetry labora-
tory. The equipment used in this setup of the processing is shown in
Figure D-3. The densitometer is located on the Kelsh plotter table.
Output from the densitometer is punched on computer cards. The operator
is able to accomplish three steps of the processing at one time. While
the densitometer is digitizing one photo, the operator is visually scanning
the line printer listing of a previous photograph searching for illegal
characters caused by double punches. At the same time he can operate the
teletype which preliminarily processes the data from another photograph
on the computer. This program reduces the voltage output from the dens-
itometer to film densities, rejects extreme values of densities, inter-
polates photo coordinates and displays the difference in film densities
between adjacant bands on the line printer. Output from this program is
stored on magnetic tape waiting final processing as explained by Burgess
and James (1969).
The densitometer and scanning table is shown in Figure D-4
processing a 70 mm picture. Voltage output from the densitometer goes
to the digital voltmeter shown directly behind the densitometer. The
BCD digital voltmeter logic (-24V = 0, - IV = 1) is converted to the
Autotrol digital recorder logic (-15V = 0, 0V = 1) by the circuit shown
in Figure D-5.
133
-------
The limits on the photograph are marked with black tape. When
the densitometer senses the tape (voltage output greater than 750 volts),
the recording of data is stopped, the direction of scan is reversed, the
film is advanced one scan and the recording of data started again. The
circuitry required for this operation is shown in Figures D-6 through
D-9. Figure 3 referred to in Figures D-6, and D-7 is Figure D-8 of the
report.

APPENDIX E
DIFFUSION COMPUTATIONS
n inv«stigators have employed solutions to the diffusion
for the estimation of waste concentrations in the waste plume
that occurs at an outfall location. If the scale of the current eddies
is much smaller than the dimensions of the waste field, then the Fickian
torm of diffusion equation can be applied. The basic equation is:
* IT * IT + aW (E-2)
where "a" is a first order decay constant and "aW" represents a sink or
loss in the system.
Early solutions to this equation assumed D constant; however,
2 82
investigators have found it to range from 3 x 10 to 4 x 10 cm /sec.
Brooks (I960) has reported a solution to the diffusion equation with a
variable coefficient of diffusivity. The coefficient was assumed to vary
with the four thirds power of the scale.
In a study of diffusion of wastes for a near shore area by the
Allen Hancock Foundation (1964), it was found that "4/3 law" relating
the lateral coefficient of eddy diffusion as a function of average eddy
scale did not hold for the particular oceanic areas studied in their
experiments. Mathematical models used in their experiments were statistical
models based on the Gaussian distribution. Another important conclusion
143
-------
reached in this study was that vertical diffusion can contribute signif-
icantly to the overall diffusion process when wind speeds exceed approxi-
mately eight knots and/or when column stability is low.
The stability of the waste field established at the outfall site
is dependent on the initial mixing from the diffusers. The initial diluti(
for a properly designed outfall should be sufficient so that the density
stratification induced by the waste field may be destroyed by vertical
turbulent diffusion. The depth of the established field at the outfall is
also a function of the initial dilution. The ratio of waste field depth
to the length of the jet path from the point of release to the water surfac
has been found by Rawn, Boweman and Brooks (1960) to vary from 1/12 to 1/6.
Vertical mixing does occur in the waste field as well as horizontal
mixing. As indicated by Wiegel (1964), vertical mixing is difficult to
study in the laboratory because of limitations of tank size. In these
studies the wind drags the surface water to the down wind end of the tank
producing a hydraulic head which causes a flow in the opposite direction.
Laboratory studies have indicated that wind drag on the water
surface produces very little mixing. However, when wind generated waves
appear, extremely rapid mixing occurs as wind waves are rotational in
the generating area. On the other hand, there is some indication that
swell is not important to the mixing process as it is apparently nearly
irrotational (Wiegel, 1964).
Masch (1961) conducted a wave study in a wave tank and developed
the following relationship for the coefficient of eddy diffusivity:
D = 0.0038 (Vs + Qw)3'2 (E-3)
where Vs is the surface current and Qw is the water particle orbit
speed (Qw = H/T, H = significant wave height and T = average wave period)
Steady state diffusion coefficients were determined for a steady
state model with unidirectional transport velocity in the X direction.
By neglecting the loss to the lower layers and assuming the diffusion
in the Y direction was not a function of Y, the basic diffusion equa-
tion becomes
V*ff • Dv 4 'E-4>
X dA ~Z
where X is the distance along the center line of the plume, Y is the
distance right or left of the plume center line, V is velocity along
the plume center line, W is the waste concentration, and the D is the
diffusion coefficient. A solution to equation E-4 is ^
144
-------
W = ryy- exp [ -Y2/4tD ]
2(11 D t)1/2 r
For computational purposes this equation can be reduced to
W = WQ exp [ -Y2/2ay2] (E-6)
where WQ is the concentration at the center line of the plume and a
is variance of normal curve. The diffusion coefficient is equal to y
one half the change in variance divided by the time interval or
In the computer program, the variance was computed every 300 feet along
the center line of the plume. The change in time for this steady state
model was equal to the distance between sections in feet divided by the
velocity in feet per second. The velocity was determined photogrammetrically
from the current floats.
o
The variance (a ) can be estimated for a normal distribution from
the sample variance (S2 ). The concentration (W) is equivalent to the
frequency of occurrence^in the computations. The sample variance is
S2 = * W(Y-Y)2 (E_8)

where Y is the mean distance from the origin and

From equation E-10 an estimate of the variance can be made for any section
across the plume. Equation E-7 was used to determine the diffusion
coefficient.
Nonsteady-state diffusion coefficients were determined from two
flights over the area using equation E-7. In this equation for the non-
steady state
Aa? = a, . 2 - a_ 2. (E-ll)
i l.,i 2, i+c v •*
where the subscripts 1 and 2 refer to the flight numbers, i refers to
the section number across the plume in flight one and i+c is the section
number in flight two adjusted for the movement of the waste field between
flights. In solving equation E-7 for the nonsteady- state case, At is the
time difference between the flights.
Diffusion coefficients presented in this report were determined
at existing outfall sites. At proposed outfall locations the currents
and diffusion coefficients can be determined by photographing dye patches.
By knowing the currents and diffusion coefficients in the area, the
waste field can be simulated on the computer prior to construction and
operation of the outfall.
Equation E-l was reduced to
§ ' Dy * Dx - W CV> - I* CVXW) * n CB-12)
where K represents the decay coefficient. This equation was program-
med to simulate the waste field from either a line source or point source
and for either a continuous effluent discharge or a dye patch.
Figure E-l is a symbolic print out of the waste field at times
0.5, 1.1, 1.9, and 3.0 hours from the start of effluent discharge. Sym-
bols in the plots represent different concentrations but at this reduced
scale only the difference in shading can be seen. While the program was
written to handle a variable velocity as a function of X, Y and T, the
146
-------
example shown here is for a unidirectional velocity of 0.3 fps. In
this example the grid size was AX = AY = 60 ft, the diffusion coef-
ficients were D = DX = 10 ft sq per sec and the decay coefficient
representing a yloss to the lower layers was 0.1 per hour.
Figure E-2 shows the effect of the diffusion coefficients on the
waste field. The symbolic plots were made 2.7 hours after the start of
the effluent discharge for D = D =5, 10, and 20 ft^/second. Except
for the diffusion coefficients, the other variables were the same as
those in Figure E-l.
This finite difference model was used to reproduce the waste
fields measured by aerial photography from the computed diffusion coef-
ficients and current velocities. The model can be expanded to include
variable diffusion coefficients and vertical mixing.

APPENDIX F
SUMMARY OF AERIAL PHOTOGRAPHY
Interference caused by direct sunlight reflection on the water
surface can be reduced or eliminated by oblique photography. Surface
foam from the waste at times may prevent the computation of waste con-
centration in the waste field from the photography. However, the photo-
graphy shows the area and extent of the foam which is valuable information
in the study of ocean outfall waste disposal.
Since the computations require that the light from the open sea
be measured, concentration determined from aerial photography are less
reliable when the waste field extends into the surf zone and background
light from the sea is not available from both sides of the plume. A
uniformly cloudy sky increases the amount of surface light reflection
in all the photographic bands. With oblique photography, most of this
reflected light can be prevented from reaching the film with a polarizing
filter. Photography containing areas of scattered shadows from partial
cloudy skies is less adapted to automatic computerized processing. Gen-
erally when broken clouds are present, the photography can be taken when
the outfall area is free of shadows.
Color film was used in the mapping camera during the 1968 season
and on July 7 and 8, 1969. Color film is difficult to process with the
rewind processor and uneven development occurs for 5 to 15 frames on each
end of the roll. The prints in Figure 21 and 22 show the uneven develop-
ment. While the effect of the film streaks can be reduced in the data
processing, it was decided in the future to use only black and white
film in the mapping camera.
Correlation coefficients between the photographic values and
the concentrations determined from boat sampling varied from 0.85 to 0.95
with a standard error of about 25% of the maximum concentration measured
over the outfall. This standard error is the same magnitude as the
standard error determined from the boat sampling data at cross lines or
points where the concentration is determined twice at one point. A
summary of the aerial photography is listed in Tables F-l and F-2.

'\ Abstract ~ ~ -—
Aerial photography taken of waste plumes from Kraft pulp mill ocean outfalls
was shown to be an effective tool in the study of waste disposal sites. This technique
is not limited by sea conditions and permits monitoring and evaluation of outfall sites
throughout the year. Photography taken at one instant provides comprehensive information
throughout the waste field. Manpower requirements and costs for this method are consid-
erably less than for conventional boat sampling surveys.
Field studies were conducted on the waste plumes from Kraft pulp mill ocean outfalls
at Newport and Gardiner, Oregon and Samoa, California. Waste concentrations were
measured by conventional boat sampling techniques while aerial photography was taken of
the outfall area from .altitudes ranging from 3,000 to 11,000 ft. Computerized procedures
were used to compute water currents, waste concentrations, toxicity zones and diffusion
coefficients from the photography.
The highest concentration measured directly over the outfalls was 2.3 percent waste
by volume and the maximum area of influence with concentrations greater than 0.2 percent
waste was 155 acres. The maximum concentration determined over the outfall for each
field study was generally less than that shown to have a detrimental effect on young
salmon for a 14-day exposure.
Surface water current was found to be the dominant factor in the resulting plume
pattern. During periods of low current velocities in the receiving water, the hydraulic
head created by the effluent source was a significant factor in the resulting plume shape.
The steady state form of the Fickian diffusion equation and unidirectional transport
velocity was not applicable to the majority of the observations.
