REMOTE SENSING REPORT
SAN FRANCISCO BAY AREA
APRIL - JULY 1972
I. INTRODUCTION
An aerial remote sensing program, requested by Region IX, was
carried out in the San Francisco Bay Area in April and July 1972.
The general area is shown in Figure 1. During the planning phase of
the mission the Bay area was divided into four sections and labeled
A, B, C and D, as outlined in Figure 1.
II. MISSION PURPOSE
The purpose of this aerial reconnaissance program was to fulfill
the following objectives:
a) Provide location and description of industrial discharges
during day and night-time periods. This effort was designed
to provide information for the waste source survey performed
by NFIC-Denver.
b) Document the presence of and dispersion patterns for the Bay
area municipal sewage treatment plant (STP) discharges during
day and night-time periods.
c) Document the flow patterns of Bay waters in the following
areas:
(1) Carquinez Bridge near the mouth of the Carquinez Strait.
(2) Bay Bridge between San Francisco and Oakland.
(3) Golden Gate Strait.

III. BACKGROUND INFORMATION
The San Francisco Bay Area is the receiving water for approxi-
mately 250 discrete sources of municipal and industrial waste dis-
charges. Approximately 150 of the waste sources are located in close
proximity to San Francisco, San Pablo, and Suisun Bays. The total
volume of wastewater discharged by these 150 sources averaged 3.1 million
cubic meters per day [mcmd] (820 million gallons per day [mgd]) in 1971.
Municipal sources contribute nearly 58 percent [1.854 mcmd] (490 mgd)
of the total wastewater volume.
The major sources of industrial wastes are oil refineries, petro-
chemical and chemical manufacturing plants, pulp/paper mills, and
food processing plants. These industries are located primarily along
the southern shore of Suisun and San Pablo Bays between the cities of
Antloch and Richmond, California.
There are 52 municipal sources that discharge an average of more
than 0.5 mgd of wastewater each. The three largest are:
a) City of San Jose - 314 thousand cubic meters per day [kcmd]
(83 mgd).
b) East Bay M.U.D. - 299 kcmd (79 mgd).
c) City of San Francisco - 242 kcmd (64 mgd) (North Point Plant).
These three sources comprise approximately 28 percent of the
total wastewater volume.
Federal installations discharge nearly 83.3 kcmd (22 mgd) of
domestic and industrial wastes into the Bay area.
IV. PHYSICAL DESCRIPTION OF THE BAY AREA
San Francisco Bay is a distinctive geographical feature in the
Northern California area; unusual hills, striking in appearance, lie
-------
on the outer periphery of the Bay area. It covers approximately
1,127 square kilometers (435 square miles). San Francisco Bay ranges
from 4.8 to 19.3 kilometers (3 to 12 miles) in width and is about
80 kilometers (50 miles) in length.
Westernmost of the numerous large metropolitan areas in the
City of San Francisco, situated on a land mass immediately south of
the strait, Golden Gate, that is the Bay connection with the Pacific
Ocean. The cities of Richmond, Oakland, and Berkeley are east of
San Francisco across the Bay from Golden Gate. To the northewast are
Martinez, Vallejo, Pittsburg, and Antioch. South of the San Francisco
area lie the cities of San Mateo, Burlingame, Redwood City, San Jose,
Hayward, San Leandro, and Palo Alto. North of the area are Rodeo,
San Rafael, Walnut Creek, Napa, Petaluma, and Antioch.
The periphery of the Bay is characterized by flatlands and tidal
marshland. Approximately 80 percent of this marshland has been "re-
claimed," chiefly for agricultural use and salt ponds. A great amount
of these lands, or shoreline, has a flat slope. As a result, the
area between mean high and low water is relatively large which totals
166 square kilometers (64 square miles). Another result of the effect
of this flat-slope topography is the shallow depth of the Bay. Average
depths are about 6.1 meters (20 feet). Immediately east of the Golden
Gate, which is only two miles wide, the average depth of the Bay in-
creases to 13.1 meters (43 feet), with a maximum depth of 40 meters
(130 feet). The Carquinez Strait maintains a maximum depth of 27.5
meters (90 feet).
-------
V. AIRCRAFT SENSOR CONFIGURATION/DATA
Four high performance aircraft were used to carry out each of the
two remote sensing missions. The sensors, carried on-board each
of these aircraft, were three cameras and an infrared line scanner
OIRLS). The cameras on each aircraft were KS-87B Aerial Framing Cameras
equipped with 152 mm (6 inch) focal length lens assemblies. They were
mounted in the aircraft in their respective vertical positions as
shown in Figure 2.
The framing cameras were up loaded with different film and optical
filter combinations as follows:
a) Camera Station 1. Kodak S0-397 Aerographic Ektachrome Film
with a Wratten HF-3/HF-5 gelatin optical filter combination.
This film is 127 mm (5 inches) wide providing a true color
transparency measuring approximately 114 mm x 114 mm (4.5"x4.5")
The filter combination prohibits ultra-violet light from
reaching the film eliminating the effects of atmospheric haze.
b) Camera Station 2. Kodak 2403 Tri-X Aerographic Film (127 mm
wide) with a Wratten 47A gelatin optical filter. This film
filter combination provides a black-white negative having
been exposed to near ultraviolet and deep blue optical energy.
This sensor was primarily used for the detection of oil slicks.
c) Camera Station 3. Kodak 2443 Aerochrome Infrared Film with
a Wratten 16 gelatin optical filter. This film is also 127 mm
wide (5 inches) resulting in color transparencies measuring
approximately 114 mm x 114 mm.

-------
The Wratten 16 filter (deep orange in color) transmits
a portion of the visible optical spectrum, i.e., deep green,
yellow, orange, red, along with the near infrared energy from
7.0 to 1.0 microns. This film presents a modified color or
false color rendition in the processed transparency unlike
the more familiar true-color films. It has an emulsion layer
that is sensitive to the near infrared in addition to the
red and green layers, whereas the true-color ektachrome
films have red, green, and blue sensitive layers. (Every
color in the visible optical spectrum is formed in the true
color film by various combinations of red, green and blue
dyes similar to the red, green and blue dots on the front of
a color television picture tube.) The modified or false
color rendition comes into play when the exposed image on
the infrared film is processed.
In the finished transparency, the scene objects (trees,
plants) producing infrared exposure, appear red in color,
while red and green objects produce green and blue images,
respectively. The most important asset of this film is
its capability of recording the presence of various levels
of chlorophyll in plant growth. The leaves on a healthy
tree will record as a bright red image rather than the usual
green. Degraded foliage will approach a brownish red color.
The orange filter is used to keep all blue light from reach-
ing the film which would cause an unbalance in the normal red,
green, blue color balance.
-------
The spectral sensitivity data for each film and the optical
filter transmittance curves are shown in Appendix A.
Information regarding the development process for each type of
film is provided in Appendix B.
The viewing angle of the KS-87 B framing cameras was 41°
centered about the aircraft's nadir as shown below:

-------
An infrared line scanner (IRLS), which records a thermal map
of an imaged area, completed the array of airborne sensors used on
this mission. The IRLS uses an infrared detector in an electroptic
system to record on film the amount of infrared energy detected in
the imaged area. The effective focal length of the IRLS is 1.15 inches
and the field of view is 120° perpendicular to the line of flight.
The three basic units in an infrared reconnaissance set are
scanner optics, a detector, and a recording unit. The scanner
collects the infrared emissions from the ground and reflects them
to a parabolic mirror. The parabolic mirror focuses the infrared
emissions onto the detector. The detector converts the infrared
energy collected by the scanner into an electrical signal. In
the recording unit the electrical signal is converted to visible
light through a cathode ray tube which is then recorded on ordinary
black and white film. The diagrams below depict the optical collection
system and the lateral field of view of the IRLS, respectively.

The airspeed and low altitude flight restrictions were imposed
by the FAA Oakland Bay TRACON Center because of the heavy commercial
and general aviation traffic in the Bay area. The jet aircraft
approach and departure patterns for the airports in this area, are

The tidal phase differences at other numerous locations in the
Bay area are given in Table VIII-2. To determine the time of high
water or low water at any station listed in this table there is given
in the columns headed "Differences, Time" the hours and minutes
to be added to or subtracted from the time of high or low water at
some reference station. A plus (+) sign indicates that the tide at
the subordinate station is later than at the reference station and the
difference is added, a minus (-) sign that it is earlier and is subtracted.
For height differences, a plus (+) sign indicates that the difference
is added to the height at the reference station and a minus (-) sign
that it is subtracted.

IX. RESULTS OF THE REMOTE SENSING DATA INTERPRETATIONS
The San Francisco Bay Area was divided into four sections
and labeled A, B, C, and D. These sections were covered by the
reconnaissance aircraft during the daylight hours on April 26,
27, 1972 and July 25, 26, 27, 1972. Two late night missions
were flown on July 26, 27, 1972 over sixteen select targets.
These targets are the eight major municipal waste sources and
the eight major industrial waste sources in the Bay area. They
are identified below and their respective locations are shown
in Figure 4.

Each waste discharge/significant indication is discussed in
outline form in the next four sub-sections of this report. The
location of each indication is depicted on the appropriate USGS 7.5
minute map by red numbers. These numbers correspond to the paragraph
numbers found in the text or body of this report. The indications
recorded during the April, July (daytime) and July nighttime missions
are identified as such. If one of the above dates is not included
for a particular location (such as July night), then no indication
was recorded during flight.
San Francisco Bay Area - Section A
This section covers the area from Pinole Point, in San Pablo
Bay, eastward through Suisun Bay to a point along the San Joaquin
River approximately 3.2 kilometers (2 miles east) of the City of
Antioch. This area is shown in Figure 5. The location of this sec-
tion is shown in Figure 1.
NOTE: Indication numbers A-l through A-10 appear on Figure 6, the
Mare Island map.
A-l April - The thermal imagery recorded a large thermal
plume around the tip of Pinole Point that ex-
tended eastward for approximately 2.14 kilometers
(7,000 feet). It is shown in Figure 7. Source of
the thermal outflow was not detected in either the
thermal or optical reconnaissance data.

A-8 April - An effluent of warm water was being discharged
through a concrete structure (4.6 meters wide
and extending 9.2 meters out into the water)
from a series of ditches originating within
the Union Oil Company. This is shown in Figure
8. This discharge produced no apparent dis-
coloration in the receiving Bay waters.
July - An identical indication was recorded. The
thermal map is shown in Figure 10.
"July Night" - A large thermal plume was generated by
this point of discharge. It is shown in Figure 9.
A-9 April - This discharge was active at the time of flight.
It produced no discoloration in the Bay waters.
The thermal map, Figure 8, indicates that the
water temperature of this effluent was some-
what cooler than that of A-8. This is shown
by the small tear-drop shaped thermal field
in Figure 8. This was recorded at a point in
time approximately one hour prior to the crest
of low-high tide. Figure 8 shows that the thermal
field was being carried toward the Davis Point
dock.
-------

DIGITALLY
-------
36
July - The outfall was active at the time of flight.
The temperature of the discharge was nearly
equal to that of the Bay waters in this immedi-
ate area. No thermal plume from this outfall
is seen in Figure 10.
"July Night" - This outfall was discharging hot water
at the time of this night mission as shown in
Figure 9. It was recorded approximately 0.5
hours after the crest of high-high tide in this
area.
A-10 April - This outfall, reportedly within the Union Oil
Company facility, was discharging warm water
at the time of flight. This is shown by the
arrow on the far right-hand side in Figure 8.
A smaller tear-drop phenomenon, than that dis-
cussed above, was recorded in this immediate
area.
July - The outfall was also active during this mission.
The temperature of the effluent was close to that
of the receiving Bay waters.
"July Night" - This outfall was discharging hot water at
the time of flight. The thermal discharges,
labeled A-8, A-9, and A-10, combined to form a
large thermal field that extended 305 meters
(1,000 fee§ out into the Bay and 915 meters
(3,000 feet) northward to the pier at Davis Point.
-------
37
Again, high-high tide had crested 0.5 hours
prior to the recording of the thermal map in
Figure 9. The influx of water into this area
carried the thermal field northward or toward
the bottom of the page.
NOTE! Indication numbers A-ll through A-22 appear on Figure 11, the
Benicia map.
A-ll April - Characteristics of a subsurface discharge were
recorded at this location. It produced no
apparent discoloration in the receiving water.
July - Same indication as April.
A-12 April - A ditch carrying a reddish-brown wastewater,
was discharging into the Carquinez Strait at
the time of flight. This ditch, approximately
6.1 meters (20 feet) wide, exited from under
the railway tracks on the southern side of the
C&H Sugar Company facility and emptied into
the Strait along the eastern side of the
Carquinez Bridge as shown in Figure 11. The
source(s) of the discharge could not be deter-
mined .
July - Identical indication was recorded.
"July Night" - This ditch was discharging warm water at
the time of flight. This is shown in Figure 9.
-------
38
A-13 April - At this particular location within the C & H
Sugar Company, two subsurface discharges were
active.
July - Water level characteristics at the time of
flight indicated the presence of the above
mentioned active outfalls and possibly a
third in the immediate area.
"July Night" - The two outfalls were discharging a
hot effluent at the time of flight. They are
shown in Figure 9. The effluents were creating
a thermal plume 92 meters (300 feet) in a
length parallel to shore.
A-14 "July Night" - Evidence of a warm discharge was recorded
at this location. Inspection of the daytime
optical imagery provided nothing to confirm
the presence of an outfall. There were several
buildings south of this area across the rail-
way tracks.
A-15 April - An orange-brown substance was being discharged
through a small open ditch into the Strait.
July - No discharge present.
A-16 April - There was a moderate discharge from a small
shoreline indentation into Carquinez Strait
with no subsequent discoloration in the receiving
waters. An STP was located in this immediate
vicinity.
-------
39
July - Identical indication recorded.
"July Night" - The discharge was warm at this time of
flight as shown in Figure 12.
A-17 April - A possible discharge was located in this area.
No significant discoloration was seen in this
area.
July - Same indication as April.
"July Night" - This waterway was quite warm as seen in
Figure 12.
A-18 April - An inactive outfall was observed at this location.
July - Identical indication.
A-19 "July Night" - A small thermal field or plume was de-
tected in this area (Figure 12) suggesting a
possible discharge. It extended approximately
12 meters out from shore.
A-20 "July Night" - A small warm outflow was recorded in
this area, as shown in Figure 12. The source(s)
could not be ascertained. The resultant thermal
plume extended nearly 15 meters (50 feet) out from
shore.
A-21 April - An active outfall was creating a dark gray
plume. The discoloration could be traced
back to an aeration pond.
July - The outfall was also active. A black substance
was floating on the water in the area of this
outfall.
-------
IGITALLY
-------
40
A-22 "July Night" - A small warm thermal plume originating
at this point, had moved west along the shore
for 15 meters (50 feet) where it had cooled to
the ambient temperature of the Strait waters.
NOTE; Indication numbers A-23 through A-35 appear on Figure 13 the
Port Chicago map.
A-23 April - This waterway was yellow-brown in color at the
time of flight. There was no visible plume or
extended dispersion pattern in Carquinez Strait.
July - Same indication as April.
A-24 April - A green-brown substance was entering the Strait
from this ditch. There was no appreciable plume
in the receiving water.
July - Identical indication.
A-25 April - The discharge from this waterway into Suisun Bay
was a gray-brown color. A moderate sized plume
was generated in the Bay and flowed in a south-
westerly direction for 200 meters (650 feet) be-
fore it dispersed sufficiently to lose its identity.
"July Night" - This discharge was warm as indicated in
Figure 12.
A-26 April - A gray-brown discharge from this ditch entered
Suisun Bay creating a small plume that moved
in a southwest direction dissipating within
75 meters (245 feet).
-------
DIGITALLY
-------
41
"July Night" - The discharge from this ditch was imaged
as being cooler than the ambient waters of Suisun
Bay.
A-27 April - The water in Pacheco Creek was a reddish-brown
color and did not create a plume as it entered
Suisun Bay.
July - Same indication as April.
A-28 April - An above-surface outfall was recorded at this
location. There was no discharge at the time
of flight.
July - Identical indication.
A-29 "July Night" - Two outfalls, reportedly from the Phillips
Petroleum Company facility, were discharging hot
effluents at the time of flight. They are shown
in Figure 14. An enlarged view is in Figure 15.
A-30 "July Night" - Two discharges were entering Grayson
Creek from the STP as shown in Figure 16. This
Figure overlaps the bottom of Figure 14.

waters.
July - Same indication.
A-39 April - Two submerged outfalls were discharging under
pressure. There appeared to be no discoloration
in the receiving waters.
A-40 April - A submerged outfall was discharging a dark brown
effluent which appeared to be a poorly treated
outflow from the adjacent STP.
"July Night" - A warm discharge was causing a moderate
sized thermal plume as shown in Figure 18.
Note; Indication numbers A-41 through A-57 appear on Figure 19,
the Antioch North map.
A-41 July - An active outfall was detected here. There was
no discoloration or plume in the receiving water.
A-42 April - An outfall just located immediately above the
water surface was discharging a reddish-brown
colored water. Sun reflection from the capillary
wave action in this area prevented the detection
of any plume.
July - The outfall was active and the plume extended out
into the slough 76 meters (250 feet) and 183 meters
(600 feet) down stream.

into the slough through a ditch originating
within the U.S. Steel Corporation complex. There
was no significant discoloration in the receiving
water.
July - Same indication.
"July Night" - The thermal imagery recorded a hot dis-
charge from the ditch as shown in Figure 20.
A-44 July - An active outfall was discharging a gray-brown
effluent into the pond. There appeared to be
no discharge from the pond into the New York
Slough.
A-45 "July Night" - The pond, mentioned in A-44, was dis-
charging into the slough at the time of flight.
The water in the pond and in the effluent were
quite warm. The point of discharge is shown
in Figure 20.
A-46 April - A large pipe was extending from the bank down to
the water. It was not discharging at the time of
flight.

shores of San Pablo Bay and San Francisco Bay to a point approximately
0.8 kilometers (0.5 miles) south of the San Francisco-Oakland Bay
Bridge. This is shown in Figure 1 and Figure 26.
NOTE; Indication number B-l appears on Figure 27, the Richmond map.
B-l April - No discernable indication recorded.
July - A small volume of greenish water was flowing
through a ditch into San Pablo Bay from an
industrial area in Rheem. The ditch contained
large surface mats of algae in its lower reaches.
NOTE; Indication numbers B-2 through B-8 appear on Figure 28, the
San Quentin map.
B-2 April - The water flowing into San Pablo Bay from
San Pablo Creek was grayish brown in color.
July - No discoloration was recorded. The temperature
of the Creek waters was somewhat cooler than
the Bay waters.
B-3 April - Moderate volume discharge through the ditch from
San Pablo S.D. Sewage Treatment Plant. No dis-
coloration of Bay waters by the effluent was
recorded. The effluent was not septic at time
of flight.
July - Effluent characteristics unchanged.

"July Night" - The STP effluent was somewhat warmer
than the Bay waters, as shown in Figure 29.
B-4 April - A large volume of wastewater was being discharged
from two adjacent locations within the Standard
Oil of California facility. These are the main
outfalls of the facility. The wastewater was
grayish brown in color and warmer than the re-
ceiving Bay waters. The amount of dissolved
oxygen was low.
July - The large volume of discharged wastewater was
present during this mission but displayed a
grayish green color in addition to being warmer
than the receiving water. The amount of dis-
solved oxygen in the wastewater was low.
"July Night" - The outfall was quite warm and covered a
portion of the mud flat area. This is shown in
Figure 29.
B-5 April - The three positions shown in Figure 28 are used,
for the most part, as overflow discharge locations.
Location "a" is a partially open ditch that originates
within the refining operational area. It was not
discharging at the time of flight. Location "b" is
a partially open ditch that connects three holding
ponds to the Bay. It was discharging a small
volume of a dark-brown substance at the time of

flight. Location "c" is also a partially open
ditch that connects the outflow of an API sepa-
rator with the Bay. No flow was recorded during
this mission. There was a significant amount of
surface algae growth in the mud flats in the im-
mediate vicinity of the outfall.
July - Locations "a" and "b" were discharging small
volumes of wastewater. No apparent discoloration
in the receiving water was observed. Location
11 c", likewise, had algae growth in the adjacent
mud area.
B-6 April - No outfall indication.
July - A yellowish brown substance was being discharged
from a submerged outfall as indicated.
B-7 April - A pipe entered the water from the base of the
Standard Oil dock. No discharge was recorded.
July - No discharge recorded.
B-8 April - A submerged outfall, discharging a dark grayish
brown substance, was located between the two
access ramps of the Standard Oil dock. The area
was surrounded by a portable surface skimmer.
It was containing nearly all of the effluent.
July - The outfall was not discharging.
NOTE; Indication numbers B-9 through B-21 appear on Figure 27, the
Richmond map.

B-9 April - A small effluent, positioned immediately above
water level, was recorded. It produced no
discoloration in the canal waters.
July - No outfall indication.
B-10 April - An outfall was discharging a small amount of
gray substance. The outfall position was im-
mediately below the water's surface.
July - No discharge was recorded.
B-ll April - A red pipe, 0.46 meters (1.5 feet) in diameter,
entered the water. No discharge was noted.
July - No discharge was recorded.
B-12 April - No discharge was recorded.
July - Water was being discharged into the Channel.
It produced no discoloration in the receiving
water.
B-13 April - A pipe, 0.92 meters (3 feet) in diameter, con-
nected a circular holding pond with the Richmond
Inner Harbor. The pond contained a dark, nearly
black, wastewater. No discharge was recorded.
July - No discharge was recorded. There was a seepage
area detected adjacent to the circular pond in
the location labeled as seepage in Figure 30.
At the time of this mission, the seepage was not
reaching the waterway projecting northward from
the Harbor.

B-14 April - There were a group of five ponds located
adjacent to the shore of the Richmond Inner
Harbor as shown in Figure 30. Ponds 1, 2,
and 3 contained a bright orange liquid sub-
stance. This waste was leaching to the Harbor
in the four areas of the figure identified
as a, b, c, and d. The wastewater was dis-
charged into pond 1. It then flowed to pond 2
and subsequently to pond 3 as indicated by the
respective arrows. The orange seepage is
entering the small "c" waterway from under the
railroad bed. Ponds 4 and 5 were also discharg-
ing to the rectangular shaped drainage ditch.
The wastewater entered the Harbor through point
"e." Pond 4 had an orange patch on its left
side. This in turn was seeping to the upper end
of the rectangular ditch.
July - Seepage to Harbor was also present.
B-15 April - No discharge from the Stege S.D. sewage treatment
plant was detected.
July - No discharge confirmed.
Information received from EPA, Region IX, indicates
that the effluent from this plant was re-routed
to the East Bay MUD in January 1971.

B-16 April - The water flowing from Cerrito Creek into
San Francisco Bay was slightly yellow-brown
in color. It dispersed quickly in the ad-
jacent mud flats.
July - The water from this creek was even more yellow-
brown and quite turbid. It, likewise, dispersed
quickly.
B-17 April - No discharge recorded.
July - A discharge was present at the time of flight.
Its location is sketched in Figure 31. The land-
fill has changed significantly from that shown
in Figure 27. The outfall produced only minor
discoloration in the water.
B-18 April - A reddish-brown discoloration was recorded in
the water at this location. The source of this
effect could not be identified. There was a
medium sized building situated near shore as
indicated by the * on Figure 27.
July - The reddish-brown effect was again present. At
this time of flight, there was chlorophyllic
growth in the water and along shore as indicated
by the parentheses.
B-19 April - One long and one short dike containing a dark
grayish-brown water were discharging to the mud

flats through subsurface structures located by
the red arrows. The origin of the long ditch,
parallel to the freeway, appears to be the
Golden Gate Fields stable area.
July - Same indication as April.
B-20 April - A large concrete culvert was recorded at this
position. It appeared to be a storm drain.
July - Same indication as April.
B-21 April - A reddish-brown substance was being discharged
from a concrete structure located by the arrow
on the map. Small amounts of oil was collecting
along shore and on the water in this triangular
area. The source could not be determined.
July - The reddish-brown substance was again present.
There was no trace of oil in this area.
Note; Indication numbers B-22 through B-27 appear on Figure 32,
the Oakland West map.
B-22 April - The water in the immediate area of the concrete
culvert structure was yellow-gray in color. The
source could not be determined.
July - Identical indication was recorded.
B-23 April - Water from a small ditch was being discharged
from the street into the mud flats with no dis-
coloration. Two buildings and a Holiday Inn
were located directly across the street.
July - Identical indication was recorded.

B-24 April - A grayish green substance was being discharged
through the rather large open conduit into the
Bay. The source appeared to be within the
buildings as indicated in Figure 33.
July - Again, this discharge was present. The waste-
water displayed an even more intense green color
during this mission. Its color characteristics
suggest an organic waste.
B-25 April - A gray substance was present in the small ditch,
as indicated in Figure 33, at the time of flight.
The flow rate was quite small. The receiving
water in the rectangular area, adjacent to
Interstate 80, was grayish green in color. There
was a discharge structure in the upper end of
this area, which appeared to be a storm drain.
July - Identical indication was recorded.
B-26 April - A brownish-yellow substance was being discharged
into the Oakland Outer Harbor at the point indicated
by the arrow in Figure 32. The plume extended
approximately 15 meters (50 feet) into the Harbor
from the dock.
July - No indication was present at the time of flight.
B-27 April - A plume, caused by the submerged outfall from
the East Bay MUD STP, was clearly visible at
the time of flight. It is shown in Figure 34.
