INTRODUCTION
A water quality study of Tallaboa and Guayanilla Bays, Puerto Rico
was conducted March 1 to April 6, 1971 by the Surveillance and Analysis
Division, Southeast Region, Environmental Protection Agency.
Specific objectives were to:
• Characterize and quantify petrochemical wastes and
cooling water discharged into Tallaboa Bay by the
Commonwealth Oil Refining Co. (CORCO) and Union
Carbide Caribe petrochemical complexes.
• Determine for the period of study the effects of
these wastes, along with cooling water discharges
of the South Coast Steam Plant into Guayanilla Bay,
on the quality and biota in Tallaboa and Guayanilla
Bays.
• Document violations of Puerto Rico's federal-state
coastal water quality standards as they apply to
Tallaboa and Guayanilla Bays.
The cooperation and assistance of the following governmental
agencies and industries during the study are gratefully acknowledged:
• Puerto Rico Environmental Quality Board
• University of Puerto Rico
• Commonwealth Oil Refining Co.
• Union Carbide Caribe
-------
FINDINGS
1. The primary waste sources tn the Tallaboa-Guayanilla Bay
study area were:
• The Commonwealth Oil Refining Co. (CORCO) —
discharges refinery wastes, petrochemical wastes
and once-through cooling water into Tallaboa Bay.
• The Union Carbide Caribe Co. — discharges petro-
chemical wastes and once-through cooling water into
Tallaboa Bay.
• The South Coast Steam Plant electrical generating
facility — discharges once-through cooling water
into Guayanilla Bay.
2. These waste sources discharged the following waste loads
during the study:
Union South Coast
CORCO Carbide Steam Plant
Cooling Water (gpm) 65,000* 54,000 181,400
Process Waste Water (gpm) 4,800* 700
Temperature Rise (°F) — 9.7 19-20
5-day Biochemical Oxygen Demand (Ibs/day) 17,050 20,860
Total Organic Carbon (Ibs/day) 7,020 8,340
Solids,Non-filterable-Suspended(Ibs/day) 32,770 14,930 —
Total Kjeldahl Nitrogen (Ibs/day) 2,144 50 —
Ammonia Nitrogen (Ibs/day) 1,500 0
Oil and Grease (Ibs/day) 3,209 610
Phenol (Ibs/day) 793 28
* Approximate values.
3. During the study neither CORCO nor Union Carbide Caribe
-------
provided the equivalent of secondary treatment for their waste discharges
as required by Puerto Rico's federal-state water quality standards. In
April 1971, Union Carbide initiated operation of a new waste treatment
facility designed to remove 80 percent of the 5-day biochemical oxygen
demand. During the study, CORCO and Union Carbide provided sediment-
ation and oil removal treatment for waste discharges. CORCO disposed
of some caustic wastes at sea.
4. The following conditions significantly influence water quality
in Tallaboa and Guayanilla Bays:
• Petrochemical wastes discharged by Commonwealth
Oil Refining Company and Union Carbide Caribe into
Tallaboa Bay.
• Location of waste outfalls from these two sources in
western Tallaboa Bay.
• Predominate tidal current patterns and easterly winds
which, due to the location of the waste outfalls,
force the waste streams to the far western shore of
Tallaboa Bay (Punta Guayanilla) and permit the excur-
sion of these wastes into Guayanilla Bay.
5. Petrochemical wastes and once-through cooling water discharged
by CORCO and Union Carbide into Tallaboa Bay and once-through cooling
water discharged by the South Coast Steam Plant into Guayanilla Bay
caused violations of Puerto Rico's federal-state water quality standards
as indicated by the following observations:
-------
• Dissolved oxygen concentrations in western Tallaboa
Bay below the 4.5 mg/1 minimum requirement.
• Water temperatures in western Tallaboa Bay and eastern
Guayanilla Bay in excess of the 4°F rise permitted.
• The formation of organic sediment deposits in Tallaboa
and Guayanilla Bays containing petrochemical residues.
• Visible oil and floating solids in western Tallaboa
Bay.
6. Water quality and biological degradation in Tallaboa and
Guayanilla Bays were indicated by the following observations:
• Relatively high concentrations of 5-day biochemical
oxygen demand (maximum of 7.6 mg/1), total KJeldahl
nitrogen (maximum of 2.85 mg/1), and ammonia nitrogen
(maximum of 0.85 mg/1) in western Tallaboa Bay.
• Reduction in the standing crop and diversity of the
community of macroinvertebrate organisms inhabiting
Tallaboa and Guayanilla Bays.
• Deterioration of the substrate and destruction of
corals by the deposition of oil and detritus in
western Tallaboa Bay.
• Proliferation of unsightly nuisance growths of film-
amentous green algae of the genera Cladophora and
Enteromorpha along the shorelines of Tallaboa and
Guayanilla Bays.
-------
7. These additional waste sources will result in increased
water quality degradation and thermal pollution in Tallaboa and
Guayanilla Bays:
• PPG Industries (Caribe) will discharge petrochemical
wastes (1600 gpm) and once-through cooling water
(39,400 gpm with a 13-15°F temperature rise) to
Guayanilla Bay when the plant begins operation in
September 1971. The discharge will also contain
0.5 Ibs/day of mercury and 10-15 Ibs/day of copper.
• Current petrochemical plant expansions by CORCO
will generate additional waste discharges into
Tallaboa Bay.
• Union Carbide petrochemical plant expansion will
result in waste discharge loadings into Tallaboa
Bay as high as those discharged before installation
of the new waste treatment system. Once through
cooling water discharges will increase by 187,000 gpm.
• Current expansion of the South Coast Steam Plant
which will result in an additional 422,300 gpm once-
through cooling water discharge into Guayanilla Bay.
8. PPG Industries (Caribe will provide sedimentation, neutral-
ization, oil removal and mercury recycling treatment for their waste
discharges when the plant begins operation in September 1971. Treat-
ment provided by PPG will not be the equivalent of secondary waste
-------
treatment as required by Puerto Rico's federal-state water quality
standards.
-------
RECOMMENDATIONS
1. An enforcement action should be initiated by the United
States Environmental Protection Agency for the purpose of establish-
ing effective pollution abatement time schedules and effluent guidelines
for present and future Tallaboa and Guayanilla Bay waste discharges.
2. As a minimum pollution abatement measure, the Commonwealth Oil
Refining Company and the PPG Industries (Caribe) Co. should install
the equivalent of secondary waste treatment as required by Puerto Rico's
federal-state water quality standards.
3. The PPG Industries (Caribe) projected mercury discharge of 0.5
Ibs/day should be reduced to conform with current Environmental Protect-
ion Agency guidelines of less than 0.1 Ib/day.
4. The new Union Carbide waste treatment system should be evaluated
by Puerto Rican Authorities to determine compliance with the secondary
treatment provisions of the federal-state water quality standards.
5. A feasibility study should be made by the Puerto Rican author-
ties and the respective industries of a joint ocean outfall which would
completely remove treated petrochemical wastes from Tallaboa and Guaya-
nilla Bays and would prevent contamination of any other coastal area.
6. The Puerto Rican authorities should not permit plant expansion
in the study area unless the equivalent of secondary treatment is provided
for additional waste discharges generated by such expansion.
7. The use of diffusers, cooling towers, relocation of outfalls
and/or other alternatives should be investigated by the Puerto Rican
authorities and the respective industries to eliminate present and future
thermal pollution problems resulting from once-through cooling water
-------
8
discharges into Tallaboa and Guayanilla Bays.
8. Dredging should be prohibited in Tallaboa and Guayanilla Bays
in areas where sediment contains petrochemical residues to prevent
sediment resuspension of organic solids and petrochemical residues,
which would cause further substrate deterioration and water quality
degradation.
9. Puerto Rican authorities should immediately begin a long-term
water quality and biological monitoring program (including fish tainting
investigations) in Tallaboa and Guayanilla Bays and adjacent to insure
compliance with applicable water quality standards.
-------
AREA
Tallaboa and Guayanilla Bays are located on the southern coast
of Puerto Rico near Ponce, the second largest city on the island
(Figure 1). The bays are bordered on the north by Guayanilla and
Penuelas municipios, Playa de Guayanilla (a small fishing village)
and a huge petrochemical industrial complex.
In the past the harvesting and processing of sugar cane was
the major industry in the area; however, in recent years industrial-
ization resulting from the establishment of the petrochemical indus-
try has dominated the economy. The Commonwealth Oil Refining Company
(CORCO) is the core of one of the largest petrochemical complexes
in the world and is the fastest growing industrial complex in Latin
America. The complex includes:
• CORCO oil refining and petrochemical operations
• Union Carbide Caribe and PPG industries (Caribe)
petrochemical operations
• South Coast Steam Plant electrical generating
facility
• Several bulk oil and chemical distributors
The primary water uses of the bays are for navigation, once-
through cooling water and industrial waste disposal. Fishing,
apparently of a subsistence nature, occurs to some degree in both
bays. Recreational use of the bays is minimal, and in view of the
continued industrial development, increased recreational use is

PHYSIOGRAPHY
GEOMORPHOLOGY
Tallaboa Bay
Tallaboa Bay is an open bay somewhat protected by five islands
and surrounding reefs (foldout map). The bay extends eastward from
Punta Guayanilla to east of the island Cayo Parguero. Bay depths
are highly variable ranging from 1 to 17 feet near the shoreline,
19 to 38 feet in the western portion near Punta Guayanilla, and 38
to 50 feet in the southern and eastern areas. (1) An extensive reef
area surrounding the islands Cayo Maria Langa and Cayo Palomas,
extends westward to the tip of Punta Guayanilla. Minor reefs are
present around all the islands. A shoaled area 11 to 15 feet in
depth extends from the shore east of the Tallaboa River to the island
Cayo Rio. A deep natural channel, 48 to 90 feet in depth, extends
into the bay between Cayo Caribe and Cayo Palomas and Cayo Maria
Langa islands.
Guayanilla Bay
Guayanilla Bay is the largest hurricane harbor in Puerto Rico.
The mouth of the bay is formed by cliff-faced Verraco Point on the
west and Punta Guayanilla on the east. (2) The entrance to the bay
is protected by an extensive reef area which extends a mile or more
offshore from Verraco Point to approximately midway to Punta Guayanilla.
Bay depths range from 19 to 60 feet in the middle and from 1 to 16 feet
along shore. (3) A lagoon, 2 to 11 feet deep, is formed by Verraco Point
-------
12
on the western side of the bay. Several large shallow depressions,
1 to 21 feet deep, are located along the eastern shore.
CLIMATOLOGY
Tallaboa and Guayanilla Bays are located in a hot (79.1°F
annual average temperature— ), dry (35.3 inch average annual rain-
2/
fall— ) area of Puerto Rico. (4) The average temperature for March
1971 was 75.7°F (0.9°F below average) with an average maximum and
minimum of 86°F and 65.3 F, respectively. (5) Rainfall for March
totaled 2.97" and was distributed during the study as follows:
• 0.02" - March 2
• Trace - March 3 and 24
• 0.51" - March 16
• 1.65" - March 18
• 0.44" - March 28
Prevailing winds during the study were northeasterly during early
morning and evening hours and southeasterly during the day. Generally,
wind velocities increased with the shift to southeasterly winds which
occurred at mid-morning. Maximum wind velocities recorded at the
Ponce airport during the study ranged from 12 to 20 mph with gusts 18
to 25 mph. (6)

HYDROLOGY
Three rivers—Tallaboa, Guayanilla and Yauco—discharge to the
Tallaboa-Guayanilla Bay system. All three are highly diverted within
their respective drainage basins and no significant flow from the
upper basins reaches the bays except during floods. River discharges
were very low during the study period, and were not considered signif-
icant sources of either fresh or polluted water and were not sampled.
Pertinent information for each river is contained in the following
tabulation. (7, 8)

TIDES AND CURRENT PATTERNS
Tallaboa-Guayanilla Bay tides are diurnal with a mean tidal
range of approximately 1 foot. (9) A predominate westward offshore
current exists off the south coast of Puerto Rico. (2)
The Water Resources Research Institute (WRRI) conducted a study
of currents (10), primarily in Guayanilla Bay, and concluded:
-------
14
• Guayanilla Bay tidal currents are directed into the
bay and northwestward at flood tide; out of the bay and
southwestward at ebb tide. (Figure 2)
• Tallaboa Bay tidal currents are directed to the northwest
(toward Punta Guayanilla) at flood tide and out of the
bay—primarily between Punta Guayanilla and nearby
islands—at ebb tide. (Figure 2)
• Windrift currents are insignificant below a depth
of 3 feet; southeast winds result in currents directed
toward Guayanilla Bay—northeast winds result in
currents directed out of the bay.
Two dye studies, one by the WRRI group and one by Ramos (11),
demonstrated that during flood tide the CORCO-Unlon Carbide waste
effluent plumes were trapped against Punta Guayanilla in Tallaboa
Bay. The net effect of these predominant current patterns is the
transport of wastes westward in Tallaboa Bay and into Guayanilla
Bay during flood tide. During ebb tide wastes flushed from
Tallaboa Bay are swept south and westward along with waters from
Guayanilla Bay. Wastes flushed from Tallaboa Bay on the ebb tide
are then in a position to be transported into Guayanilla Bay by
the following flood tide and wind generated currents.

WATER QUALITY STANDARDS
The waters of Tallaboa and Guayanilla Bay are classified for
industrial usage, Class SE. Puerto Rico Sanitary Regulation 131
contains the water quality standards adopted for Federal and Common-
wealth purposes. The applicable sections of this regulation are
reproduced below.
GENERAL CRITERIA
Article III - Pollution Discharges
A. It is hereby prohibited to any person, to directly or indirectly
throw, discharge, pour or dump and/or cause or allow to be thrown
discharged, poured, or dumped into the coastal waters of Puerto
any kind of domestic or industrial wastes with less than convent-
ional secondary treatment or control or its equivalent, or any
other substances capable of polluting or creating a potential
threat of pollution in such a way that coastal waters be rendered
below the minimum standards of purity established in these Rules
and Regulations.
B. Notwithstanding the foregoing prohibitions, the Secretary of
Health may upon application to that effect, grant permission for
drainage into the coastal waters when the discharged substances
have been previously submitted to a proper degree of treatment.
The degree of treatment will be as specified above in Part A,
Article III, unless it can be demonstrated to the Secretary of
Health, that a lesser degree of treatment or control with approved
ocean outfalls will not degradate the water quality. Since
these are also Federal standards, these waste treatment require-
ments will be developed in cooperation with the Federal Water
Pollution Control Administration.
C. Coastal waters whose existing quality is better than the estab-
lished standards as of the date on which such standards become
effective will be maintained at their existing high quality.
These and other coastal waters of Puerto Rico will not be lowered
in quality unless and until it has been affirmatively demonstrated
to water pollution control agency for Puerto Rico that such
change is justifiable as a result of necessary economic or social
development and will not interfere with or become injurious to
any assigned uses made of, or presently possible in, such waters.
This will require that any industrial, public, or private project
-------
16
or development which would constitute a new source of pollution
or an increased source of pollution to high quality waters will be
required, as part of the initial project design, to provide the
best practical degree of treatment available under existing
technology, and since these are also Federal standards, these
waste treatment requirements will be developed in cooperation
with the Environmental Protection Agency.
SPECIFIC CRITERIA
Article V - Classification and Standards of Quality for the Coastal
Waters of Puerto Rico
Class SE - Includes the coastal water which are destined for or may
be destined for industrial usages.
Quality Standards
The coastal waters Included in Class SE shall not contain:
a. Floating solids, settleable solids, oils, and sludge deposits
which are readily visible and attributable to municipal, industrial
or other wastes or which increase the amounts of these constituents
in receiving waters or any other material or waste that would inter-
fere with the aesthetics of these waters.
b. Any type of garbage, cinder, ash, oil, sludge, or other refuse.
c. Dissolved oxygen in a concentration of less than four and a half
(4.5) milligrams per liter.
d. Toxic wastes, or deleterious substances alone or in combination
with other substance or wastes in sufficient amount as to prevent
the survival or propagation of fish life or impair the waters for
any other best usage as determined for the specific waters which
are assigned to this class.
e. A pH factor less than six and eight tenths (6.8) or more than
eight and five tenths (8.5).
f. A temperature more than 4°F above ambient water temperature and
in no case in excess of 93°F.
-------
17
WASTE SOURCES
The primary waste sources in the study area are petrochemical and
refining operations. Municipal wastes are relatively insignificant
because of sparse population densities and the small percentage of urban
areas sewered.
MUNICIPAL WASTES
Three municipalities—Yauco, Guayanilla, and Penuelas—discharge
municipal wastes to area streams. All municipalities except Penuelas—
which has an imhoff tank—provide secondary sewage treatment for small
sewered urban areas. The following tabulation summarizes the sanitary
waste data for these municipalities. (12)

Several fishing villages and coastal communities located in the
area do not have sewerage systems or treatment. Municipal waste dis-
charges were considered minor when compared to the industrial waste
discharges and were not sampled during the study.
INDUSTRIAL WASTES
Both Tallaboa and Guayanilla Bays are navigable and have docking and
unloading facilities for ships and barges. These facilities are used for
-------
18
the unloading of raw products destined for the petrochemical complexes and
the shipment of finished products. Spillage of raw and finished products-
crude oil and petrochemicals—are bound to occur. Although these spills
are not quantifiable, they may constitute a major source of pollution.
Commonwealth Oil Refining Company
General
The Commonwealth Oil Refining Company (CORCO) was the first industry
established under Puerto Rico's Operation Bootstrap and today is the
largest industrial firm on the island. (13) The CORCO refinery processes
a wide range of crude and unfinished oils for the production of aviation
and motor gasoline, jet fuel, kerosene, diesel fuel, oil, and other
products. The refinery processed 115,000 bbls/day of oil in 1970 and
will process 175,000 bbls/day in 1972 after a major refinery expansion
is completed. (14)
There are currently six petrochemical plants operating in the CORCO
complex:
o CPI-1 and CPI-2, wholly owned by CORCO, producing benzene,
toluene, and mixed xylenes.
o Two Hercor plants, a joint venture of CORCO and Hercules
Powder Company, producing paraxylene and mixed xylenes.
o The Sacci plant (styrochem plant) , a joint venture of
CORCO and Royal Dutch Shell, producing cyclohexane.
o The Oxochem Plant, a joint venture of CORCO and the
Grace Company, producing alcohols—mainly isobutanol.
-------
19
An Olefins plant, a joint venture with PPG Industries, will be completed
in the near future and will produce propylene and ethylene. These pro-
duction areas along with future expansion areas are shown on Figure 3. (15)
Wastewater and Waste Treatment Facilities
Wastes from CORCO include oily waters, sour and caustic streams,
cooling water return and storm waters. The water balance and wastewater
systems—detailing the flow of cooling, process and wastewaters—for
the refinery area and CPI-1 (representing most of the waste discharge)
are shown on Figure 4. (16)
Approximately 900 gallons per minute (gpm) of oily waters from
the refinery area area collected in an interconnected series of oily water
sewers. Some 450 gpm of oily waters, including sour waters and caustic
wastes are discharged to the existing saltwater ditch where they are
mixed with return cooling water and transported to the treatment area.
Oily waters from CPI-1 (approximately 150 gpm) are treated in an existing
API separator and discharged to the saltwater ditch. Once-through cooling
water from the refinery area (approximately 65,000 gpm) is discharged to
the existing waste lagoons. Wastewaters from the Styrochem and Hercor
plants are discharged to the waste system downstream from the API separa-
tors.
Oily waters from CPI-2 are treated in an API separator and are cur-
rently discharged to Tallaboa Bay through a submerged outfall pipe (see
foldout nap). This discharge will be routed in the future to a waste
stripping column and will be cycled to the cooling tower system. Slowdown
from freshwater cooling towers, boiler blowdown, and concentrated brine

from a desalinization plant—approximately 1.6 times bay salinity—
are also discharged through the submerged outfall. Total discharge
through the outfall is approximately 1,700 gpm and is composed of the
following:
o Desalinization plant concentrated brine - 1,275 gpm
o CPI-2 effluent from API separator - approximately 200 gpm
o Cooling tower blowdown - 210 gpm
o Boiler blowdown - 15 gpm
Except for waste streams previously discussed, sour water and
caustic wastes from plant operations, including those from the Oxochem
plant, are stored and then disposed of at sea.
Some stormwater from the complex enters the existing lagoon system.
Stormwater from the Styrochem, Hercor, and CP1 plants discharge into the
Tallaboa River. A portion of the stormwater that discharges into the
Tallaboa River passes through a one million gallon impoundment.
Existing waste treatment facilities serving the refinery area and
CPI plants include API separators and four lagoons. Three of the lagoons
are identical rectangular units with a total 14 million gallon capacity
at a water depth of five feet. The fourth lagoon is triangular in
shape and receives the discharge from the three rectangular lagoons. The
capacity of the triangular lagoon is 5.6 million gallons at a water depth
of 1.5 feet. Total discharge of mixed wastewater is estimated at 96.2
mgd. The lagoon system has a theoretical detention time of about live
hours. The lagoon system functions as a secondary oil separation facil-

ity and settling basin. Efficiency of treatment data were not available
for the system. CORCO's waste treatment system does not meet the require-
ments of Puerto Rico's federal state water quality standards which require
the equivalent of secondary treatment— for industrial wastes.
Union Carbide Caribe
General
Union Carbide Caribe produces refined ethylene glycol, refined
diethylene glycol, diethylene glycol residue (crude diethylene
glycol - 50% di, 50% tri), butadiene, dripolene, ethyl-hexonal,
iso-butanol, butanol, and some by-products. (17)
Raw product is supplied to the Union Carbide complex by CORCO. A major
plant expansion is presently underway which will permit the production
of 775 million pounds per year of ethylene and derivative products
including butadiene, ethylene oxide, phenol, cumene, polyethylene, bis-
phenol-A, and plasticizers. The Union Carbide complex is shown in
Figure 5.
Wastewater and Waste Treatment Facilities
The existing petrochemical complex discharges approximately
15,000 Ibs/ day of 5-day biochemical oxygen demand (BOD ) at a flow rate
of 700 gpm. (18) The waste load expected from the new units, including
the existing waste load, contaminated storm water and spills is expected
to be 50,000 Ibs/day of BOD5 at a flow rate of 3000 gpm. The 63,000 gpm
I/ Assumed to be the equivalent of biological secondary waste treatment
a minimum 85 percent removal of 5-day Biochemical Oxygen Demand and
substantially complete removal of suspended solids.

of once-through cooling water currently used will increase to 250,000 gpm
when the new process units go on line. Treatment facilities in operation
during the study included skimmers and the two primary settling basins
shown on Figure 5. This waste treatment system did not meet the require-
ments of Puerto Rico's federal-state water quality standards which require
the equivalent of secondary treatment for industrial wastes. However,
in April 1971, after the completion of this study, Union Carbide initi-
ated operation of a new waste treatment system for the existing plant
and the current expansion.
The new waste treatment system provides for:
• Complete segregation of cooling water from process
wastes.
• Process sewers to collect continuous or intermittent
waste discharges.
• Storm sewer system to collect equipment washings, pad
washings, storm and fire water.
Oil skimmers basins are installed on the storm sewer effluents from each
unit. Floating oils or spills of light hydrocarbons plus storm runoff
(up to approximately 75 gpm) are diverted to the process sewer. Thus,
this system diverts to the treatment plant all spills, wash water and
the first part of any rainfall or fire water flow.
The new waste treatment facility - designed for 80 percent removal -
provides primary and biological waste treatment for the total wastewater
flow. Major components of the new system include primary treatment,
neutralization, equalization and biological treatment using an anaerobic
-------
23
pond-aerated stabilization system. The waste treatment system is shown
in schematic form in Figure 6. Major components of the system, including
design criteria, are summarized in Table 1. (18, 19)
PPG Industries (Caribe)
General
The PPG complex will begin limited production in September 1971.
When the complex begins full operation, these principal products will
be produced:(20)
• Caustic Soda - 400 million Ibs/yr
• Vinyl Chloride Monomer - 500 million Ibs/yr
• Ethylene Glycols - 415 million Ibs/yr
Other products which will be produced in smaller volume include
sodium hypochlorite, chlorine, muriatic acid, and ethylene dichloride.
Production areas are shown in Figure 7.
Wastewater and Waste Treatment Facilities
PPG will discharge approximately 41,000 gpm of wastewater from the
complex of which approximately 39,400 gpm will be once-through cooling
water. It is anticipated that 1,600 gpm of the discharge will pass
through their "treatment" area.
A comprehensive projection of wastewater composition was not supplied
by PPG. However, they expect to discharge:
• Mercury - 0.5 Ibs/day
• Copper -•10-15 Ibs/day
• Ethylene Glycol - 648 Ibs/day

The final effluent from PPG will have a pH of 8.0 to 8.3, and the
entire discharge will be raised 13-15°F higher than ambient bay
temperature.
PPG will provide oil removal and neutralization for industrial
wastes and secondary treatment with chlorination for sanitary wastes.
Three separate sewer systems discharge to the treatment area (Figure 8):
o Sanitary sewers: collects sanitary wastes only—
discharges to package secondary sewage treatment plant.
o Oily water sewer: collects neutral and low solids
wastes—discharges to API oil separators.
o Salty water sewer: collects wastes with high dissolved
solids and wastes which need pH adjustment—discharges
to limestone pits.
Sanitary wastes after secondary treatment and chlorination are dis-
charged to a 2 million gallon utility water pond. Effluent from the
API separators are also discharged to this pond. The pond, which will
supply water to the plant for fire and utility purposes, is equipped
with two aerators and a portable oil skimmer. The purpose of the aerators
is to supply dissolved oxygen to these wastewaters if it becomes necessary,
The pond will discharge to the seawater return canal. Oil collected in
the API separators will be burned in a high-temperature submerged combus-
tion incinerator.
-------
25
Wastes from the salty water sewer are pumped into two parallel lime-
stone beds. The discharge from the limestone beds flows into a retention
pond and then into the seawater return system. The limestone beds will be
continually monitored for pH, and pH adjustments will be made on the efflu-
ent if necessary.
Recycling, recovery, and treatment steps for the containment of mer-
cury from the chlorine production process have been installed by FFG.
PPG1s industrial waste treatment facilities will not meet the provis-
ions of Puerto Rico's federal-state water quality standards which require
the equivalent of secondary treatment for industrial wastes.
South Coast Steam Plant
The South Coast Steam Plant electrical generating facility is
located on the northeast shore of Guayanilla Bay between CORCO and PPG
(foldout map). The plant currently generates 280 MW of electricity with
four generating units withdrawing 181,400 gpm of once-through condenser
cooling water from Guayanilla Bay. (21) A heat rise of 19 to 20°F was
observed in the cooling water returned to the Bay during March 1971.
A major plant expansion is underway which will give the plant an
additional generating capacity of 850 MW and will require an additional
422,300 gpm of cooling water.
A series of temperature profiles were made in Guayanilla Bay on
March 13 to determine the distribution of the power plant's cooling
water in the bay. This study is discussed in the Water Quality section.

RESULTS AND DISCUSSION
WASTE SAMPLING
Waste sampling was limited to refining and petrochemical wastes
discharged by the Union Carbide and Commonwealth Oil Refining Company
(CORCO). Waste loads discharged by these two complexes into Tallaboa Bay
are summarized in Table 2. Allowance was made in the Union Carbide waste
load for concentrations found in the Union Carbide seawater intake which
could have resulted from the CORCO submerged outfall and/or the Union
Carbide and CORCO main effluents. The samples collected from the main
CORCO waste outfall (CORCO 22) and the Union Carbide waste outfall (UCC-21)
represented the combined wastewater and once-through cooling water dis-
charges from these sources. Data are based on nine 24-hour composite
samples and company-supplied discharge data from each waste source.
Visible patches of oil, varying in size from several square inches
to approximately one square foot, were noted in the main CORCO waste
canal on three occasions during the first week of the study. These oil
patches resulted from an opening in a straw boom located just downstream
from the lagoon system. The boom was apparently repaired because no
further oil patches"were observed on the canal surface. A white fila-
mentous algae was observed to be continuously discharged from the CORCO
lagoon system and was visible in the effluent of the main waste canal.
'Visible oil patches were detected on the Union Carbide waste canal
during the study period. These oil patches varied in size from several
feet to patches which covered the entire canal surface. Oil was contin-

uously released from the sediment on the bottom of the canal and
could be observed bubbling to the surface.
Gas chromatographic analyses of effluent samples from the main efflu-
ent canals of Union Carbide and CORCO and the CORCO submerged outfall
showed many organic compounds in the microgram/liter concentration range."
The main CORCO effluent canal had the highest output of total organic
pollutants as shown by the oil and grease and phenol analyses and is a
major source of organic and ammonia nitrogen. Both industries discharge
significant amounts of solids (non-filterable, suspended) into Tallaboa
Bay. Neither CORCO nor Union Carbide discharge significant amounts
of nitrate-nitrite nitrogen or phosphorus compounds into Tallaboa Bay.
A summary of waste sampling data is contained in Table 3. A complete
listing of all waste data is contained in Appendix F.
The main CORCO effluent (CORCO 22) contained zinc, iron, molyb-
denum, mercury, and manganese. Since CORCO obtains saltwater cooling
from Guayanilla Bay which has concentrations of iron, zinc, molybdenum
and mercury similar to those found in the main CORCO effluent, it was
surmised that CORCO is merely cycling these metals from Guayanilla Bay
to Tallaboa Bay through their cooling water system. The CORCO submerged
outfall (CORCO 19) contained concentrations of zinc, iron, molybdenum,
maganese, copper, and mercury higher than those found in Tallaboa Bay.
These metals are probably concentrated in brine from the desalinization
plant. There are no other known mercury sources in the CORCO complex.
The extremely high copper loss Indicates corrosion problems in the~desalt-
l/ Since no single compound was found in concentrations higher than the
microgram per liter range, no attempt was made to identify specific
organic compounds.

ing plant.
The main Union Carbide effluent contained iron, molybdenum, manga-
nese and cobalt in concentrations higher than those detected in the
seawater intake. The Union Carbide Tallaboa Bay seawater intake contained
quantities of mercury higher than that found in the main effluent; thus,
mercury is merely being recycled through the Union Carbide cooling system.
Although CORCO did not report any unusual operating conditions or
plant upsets during the study, two events did occur at the Union Carbide
Complex which could have affected sampling results. On the morning of
March 8, 1971 organic wastes were lost from the oxo-sewer skimmer basin
and on the night of March 19, 1971, a major fire occurred in the olefin
units.
WATER QUALITY
The waters of western Tallaboa Bay were found to be severely degraded.
This water quality degradation was characterized by the following observa-
tions :
• Dissolved oxygen concentrations below the 4.5 mg/1
minimum required by the water quality standards.
• Water temperatures in excess of the 4°F rise above
background water temperatures permitted by the
water quality standards.
• Visible oil films and suspended solids.
• High concentrations of 5-day biochemical oxygen
demand (maximum of 7.6 mg/1).
-------
29
• High concentrations of total Kjeldahl nitrogen
(maximum of 2.85 mg/1) and ammonia nitrogen (maximum
of 0.850 -rag/I).
Water temperatures in eastern Guayanilla Bay were also found to
be more than 4°F higher than background.
Three overriding conditions influence the water quality of
Tallaboa and Guayanilla Bays:
• Petrochemical wastes discharged by Commonwealth
Oil Refining Company and Union Carbide Caribe into
Tallaboa Bay.
• Location of waste outfalls from these two sources
in western Tallaboa Bay.
• Predominate tidal current patterns and easterly winds
which, due to the location of the waste outfalls,
force the waste streams to the far western shore
of Tallaboa Bay (Punta Guayanilla) and permit
the excursion of these wastes into Guayanilla Bay.
Average water quality results from Tallaboa and Guayanilla Bay
water quality and diurnal sampling are presented in Table 4 and are
discussed in detail in the following sections. These average data
•represent samples collected at three high water and three low water
slack tidal conditions at fifteen stations and two diurnal surveys
at eight sampling stations. A complete listing of all water quality
data collected and sampling stations used during the study are
included in Appendices G and C respectively.

Dissolved Oxygen (DO)
Substandard—less than 4.5 mg/1—DO concentrations were measured
at six sampling stations in Tallaboa Bay:
• TB-2 (1 sample)
• TB-3 (1 sample)
• TB-5 (1 sample
• TB-6 (6 samples)
• TB-7 (11 samples)
• TB-8 (1 sample)
With the exception of a single sample at TB-2, all substandard DO con-
centrations were measured within the influence of waste streams from
CORCO and Union Carbide. Minimum DO concentrations measured during
the study are shown in Figure 9. DO concentrations exceeded minimum
standard values at all Guayanilla Bay stations.
Results of the two diurnal DO studies indicate that tidal fluctuations
were a contributing factor in short term DO variations. This variation was
most pronounced in Tallaboa Bay (Figure 10). It appears that DO increases
with the flooding tide east of the waste outfalls—stations TB-1 and TB-3—
and decreases near the waste outfalls (TB-6 and TB-7), while DO concentra-
tions increase near the waste outfalls on the ebbing tide. This is consist-
ent with tidal current patterns (Figure 2) and indicates that petrochemical
wastes are trapped against Punta Guayanilla and exert a significant
oxygen demand on these waters during flood tide.

Significant DO stratification was noted in Tallaboa Bay along Funta
Guayanllla at stations TB-6, TB-7, and TB-8 — sampling stations which
were directly affected by waste discharges — where average surface DO
concentrations were 0.5 to 1.0 mg/1 less than bottom values. The DO
stratification was also noted in Tallaboa Bay at Station TB-5 and
in Guayanilla Bay at GB-14 where average surface concentrations were
0.5 mg/1 higher than bottom concentrations.
Organic Materials
Organic materials of petrochemical origin such as those detected in
waste effluents were not detected in bay waters at the minimum detection
limit of the analysis (5 yg/1). This was due to dilution, volatilization,
adsorption on silt, and degradation which would reduce the concentration
of organic pollutants after discharge.
A measure of the biodegradable (oxygen demanding) organic material
present in Tallaboa and Guayanilla Bays was provided by the five-day
Biochemical Oxygen Demand (BOD,-) analysis. The average BOD distribution
(Figure 11) was essentially the same at flood and ebb slack tidal condi-
tions. The highest average BODe (4.4 mg/1) and individual BOD- (7.6 mg/1)
concentrations occurred adjacent to the CORCO-Union Carbide waste dis-
charges (TB-6) in Tallaboa Bay at low water slack. The BOD^ concentrations
decreased along Guayanilla Point to the south and southeast at both
tidal conditions.
Excessive BOD^ values were not observed in Tallaboa Bay in areas
which were not immediately adjacent to waste outfalls. Low BODe, values
in these areas result from settling of organic solids, dilution, and lower
biodegradation (reaction) rates which occur in salt water. Average BODe

in Guayanilla Bay was near background (0.3 to 0.8 mg/1) and did not
vary significantly with tidal fluctuations.
Turbidity
Average turbidity concentrations in both bays were highest at
low water slack tide. Highest turbidities were found offshore from the
waste outfalls in Tallaboa Bay and at the extreme upper end and mouth of
Guayanilla Bay. Turbidity concentrations were consistently higher by 1
to 7 JTU near the bottom at 13 of the 15 sampling stations indicating
resuspention of sediment material.
Most of the turbidity concentrations observed in extreme western
Tallaboa Bay are directly attributable to the CORCO and Union Carbide
waste discharges. The turbidity in the remainder of Tallaboa and
Guayanilla Bays was probably due to the resuspension of bottom sediments
deposited in these bays by past discharges of the Tallaboa, Guayanilla
and Yauco Rivers. All three rivers were at extremely low flow during
the study and did not contribute to the observed turbidity in either Bay.
Nitrogen and Phosphorus
Nitrate-nitrite nitrogen and phosphorus concentrations were uniformly
low in Tallaboa and Guayanilla Bays. The highest nitrate-nitrite nitrogen
concentrations — 0.09 mg/1— occurred adjacent to the CORCO waste out-
fall in Tallaboa Bay at station TB-6. Nitrate-nitrite nitrogen values
ranged from 0.01 to 0.04 mg/1 and averaged 0.01 to 0.03 mg/1 at all
other sampling stations in both bays. Total and orthophosphorus concent-
rations were low — 0.02 to 0.03 mg/1 — in both bays at all tidal
-------
33
conditions.
Total Kjeldahl nitrogen (TKN) concentrations (organic nitrogen
plus ammonia) were approximately 50-100 percent greater at high water
slack than low water slack tidal concentrations for most sampling stations
(Figure 12). The maximum TKN concentration (2.85) occurred at sampling
station TB-4. Generally the TKN gradient decreased from the CORCO (the
only major source of TKN) waste outfall eastward and southward out of
Tallaboa Bay at high and low tides. The gradient increased from the
mouth of Guayanilla Bay northward and westward and from the head of Guaya-
nilla Bay southward and westward at high water slack indicating that the
source of at least some of the Guayanilla Bay TKN were due to the CORCO
waste discharge. At low water slack, the Guayanilla Bay gradient decreased
southward. Generally, TKN concentration gradients followed the tidal
current patterns.
At most sampling stations, average ammonia concentrations were
50 to 1500 percent higher at high water slack in both bays. The maximum
ammonia concentration (0.85 mg/1) occurred in Tallaboa Bay near Punta.
The TKN gradients at high water slack decreasing from the CORCO waste
outfall eastward and southward out of Tallaboa Bay. At low water slack,
Tallaboa Bay ammonia concentration gradients decreased eastward. No
particular ammonia gradient was detected in Guayanilla Bay at low water
slack.
/
The organic and ammonia nitrogen discharged into Tallaboa Bay
principally by CORCO contribute to oxygen depletion and provide the
nitrogen necessary for the growth of the nuisance algae Enteromorpha

predominate benthic algae from found near the CORCO waste discharge and
along Funta Guayanilla where TKN concentrations were highest.
Metals
Metal analyses of special composite samples collected from three
Tallaboa and three Guayanilla Bay sampling stations are shown in Table 5.
These composite samples were collected March 19, 1971 from surface
locations at flood and ebb slack tides.
Metal concentrations detected which were higher than those normally
found in seawater (22) or which were above the detection limit of the
enmisslon spectrographic analysis included zinc, iron, molybdenum,
chromium (hexavalent), and mercury. The purpose of sampling the bay
waters for metal concentration was to trace gross pollution. It should
be noted that natural seawater concentrations of some of the metals
were below the detection limit of the analysis, and these data are not
interpretable.
Higher than normal concentrations of mercury, zinc, iron, and molyb-
debum were found in Guayanilla Bay. Zinc concentrations decrease from the
mouth of the bay northward indicating an external source of this metal.
However, mercury, iron, and molybdenum concentrations decrease from the
upper end of the bay southward. The high concentrations of these metals
in the upper end of the bay, particularly mercury, suggest a source of
pollution in this area which was not measured during the study.
Higher than normal concentrations of mercury, molybdenum and chromium
(hexavalent) were found in Tallaboa Bay. Both CORCO and Union Carbide

detectable amounts of chromium. Some mercury (5.35 yg/1) was detected
in the CORCO submerged outfall effluent. CORCO refinery cooling water
is withdrawn from the area of Guayanilla Bay where mercury concentrations
were highest. This cooling water is returned to Tallaboa Bay and may
account for some of the mercury detected in bay waters.
None of the metals were found in concentrations which are known
to be toxic to fish or other marine organisms. (23,24). However, some
of the metals — copper, mercury and zinc — are known to be concentrated
by plankton, benthic organisms, shellfish, and fish. The Puerto Rico
Government will investigate the unknown source of mercury and will
resample the area to confirm the mercury analyses.
Temperature
Temperature standards violations—4°F above background and/or 93°F
maximum—appear to be limited to that portion of Tallaboa Bay immediately
adjacent to Punta Guayanilla near the CORCO-Union Carbide waste outfalls
and that part of Guayanilla Bay immediately adjacent to the South Coast
Steam Plant. Using the temperature at sampling station TB-1 (most east-
erly station in Tallaboa Bay) as ambient and restricting the analysis
to those temperatures measured at known tidal conditions, water quality
standard violations were found at TB-2(3/11/71), TB-3(3/11/71), and
TB-6(3/18/71). The distribution of maximum temperatures recorded during
the study, Figure 13, clearly shows that the highest temperatures are
limited to the areas noted previously. Pronounced vertical temperature
stratification—average of 2.5 and 3.0°F higher surface temperatures—

was found along Guayanilla Point near the CORCO-Union Carbide waste
outfalls (station TB-6 and TB-7).
On March 13, 1971 a special temperature profile was made in Guayan-
illa Bay — within 1-1/2 hours of low water slack tide — to determine
the distribution of heated waters discharged from the South Coast Steam
Plant. The highest temperatures, Figure 14, were confined to the lagoon
immediately adjacent to the cooling water discharge and the extreme
eastern portion of the bay south of the plant. Using the temperature
at GB-13 as a control (80.5 to 81.5°F) in the water column, temperature
standards were found to be violated in the small lagoon into which the
power plant discharges and in that portion of the bay close to the lagoon.
Heat .is rapidly dissipated in the deeper water of Guayanilla Bay. Petro-
chemical and power plant expansions will increase the size of the temper-
ature violation zone unless provisions for cooling are made.
H
The pH values ranged from 7.9 to 8.4 in both bays, averaging 8.1 to 8.2
at every sampling station. There were no significant differences in pH
values due to tidal variations at any station and no water quality stand-
ards violations were noted.
Chloride
Average chloride values were uniform throughout both bays (20,200 to
20,900 mg/1), with high water slack tide values—100 to 500 mg/1 higher
than low water slack values. There were no significant chloride gradi-
ents chloride stratification, at flood or ebb slack tide in either bay.

These data indicate that at low freshwater discharge both Tallaboa and
Guayanilla Bays are vertically well mixed bodies of water.
Aesthetics
Floating solids, settleable solids and oils which are readily
visible are specifically prohibited by the Federal-State Water Quality
standards applicable to Tallaboa and Guayanilla Bays. Two specific
violations of this provision of the water quality standards were observed
during the study:
• On March 11, a brown plume was observed emenating
from the area of the CORCO and Union Carbide waste
canals and extending southward in Tallaboa Bay along
Punta Guayanilla. The plume was approximately 100-
150 yards in width.
• On March 19, an oily sheen was observed in Tallaboa
Bay in approximately the same location and covering
the same area as the brown plume.
When disturbed, oil and suspended solids are released from sediments
along Punta Guayanilla in Tallaboa Bay. This phenomenon was observed on
numerous occasions during the study when sediments were disturbed by
propeller wash and biological and sediment sampling procedures.
SEDIMENT CHARACTERIZATION
Organic materials and metals in concentrations too low to be measured
in water may often be present in sediment at detectable levels. This
-------
38
phenomenon occurs as polluting materials settle or are removed from
solution by biological or physical-chemical processes. The presence of
these materials in sediment is useful as a tool in tracing the distribu-
tion of polluting materials discharged into water bodies.
Sediment characterization study results show that deposits of organ-
ic material of petrochemical origin exist in Western Tallaboa Bay. The
most extensive deposits were located along the entire eastern shore of
Punta Guayanilla and immediately adjacent to the outlets of the CORCO
and Union Carbide waste canals. Petrochemical residues were also present
in Guayanilla Bay sediment. Concentration gradients definitely established
that waste discharges from CORCO and Union Carbide are the source of
organic sediment deposits of petrochemical origin. The existence of
these sediment deposits is a direct violation of Puerto Rico's federal-
state water quality standards.
The build-up of these organic sediment deposits which have resulted
from the CORCO and Union Carbide waste discharges of petrochemical resi-
dues and solids have:
• Completely destroyed the original (natural) Tallaboa Bay
substrate along the eastern shore of Punta Guayanilla.
• Contributed to the deterioration and destruction of the
natural substrate and corals in the adjacent waters of
Tallaboa and Guayanilla Bays. (See biological studies
section).
Other potential damaging effects of these organic sediment deposits
-------

on the ecology of Tallaboa and Guayanilla Bays may include:
• Biological magnification of pollutants originating at
the sediment-water interface resulting in fish flesh and
shellfish tainting.
• Exertion of a significant oxygen demand on adjacent
waters as the sediment deposits are biologically degraded.
Thirty-three sediment samples were collected from Tallaboa and
Guayanilla Bays for analyses. Analytical results are presented in
Table 6 and are discussed in detail in the following sections.
Oil and Grease
Oil and grease analysis, Figure 15, of sediment samples showed sig-
nificant concentrations of organic pollutants in both Tallaboa and Guaya-
nilla Bays. The highest concentrations (dry wt. basis) were detected in
Tallaboa Bay near Punta Guayanilla adjacent to the waste outfalls (12,650
mg/kg) and near the tip of the point (45,600 mg/kg). Concentration gra-
dients of oil and grease in sediment decrease from this area eastward
in Tallaboa Bay and westward into Guayanilla Bay. Oil and grease were
detected as far west as Punta Verraco, the westerly limit of the project.
The deposition of organic materials closely follows the tidal current
patterns of Tallaboa and Guayanilla Bays (Figure 2). The heaviest deposi-
tion of these materials was along Punta Guayanilla with progressively
less deposition in eastern Tallaboa Bay and Guayanilla Bay. Oil and
grease concentration gradients clearly indicate that discharges from
CORCO and Union Carbide are the source of this deposition.

Gas chromatographic analyses confirm that the sediment oil and
grease residues were petroleum. A comparison of gas chromatograms
of weathered Talco crude oil,i' waste effluents and sediment extracts
from Tallaboa and Guayanilla Bays are shown on Figure 16. Chart 1
is Talco crude, charts 2 and 3 show the effects of weathering on this
crude oil. The similarity of chart 1 (Talco crude) and chart 4 (CORCO
main effluent canal waste) are apparent. Note also the similarity of
chart 5, the Union Carbide effluent (UCC 21), to chart 1, Talco crude.
Petroleum chromatograms are characterized by an abundance of peaks stand-
ing out above a broad "envelope" that represents a large number of incom-
pletely separated compounds (25). This is quite evident in charts 1 and
4 — note the loss of these peaks upon weathering (charts 2 and 3). Sed-
ment extract gas chromatograms (charts 6-11) also exhibit the loss of
peaks above the "envelope" caused by weathering. However, the "envelope"
on the sediment extract gas chromatograms is still well defined and is
typical of weathered crudes. There is a marked similarity of retention
times for the "envelope" maxima in the main CORCO effluent (chart 4) and
the sediment extract from station TB-7 (chart 6). The similarities of
retention times in the "envelope" maxima for the Union Carbide effluent
(chart 5) and the remaining sediment extracts (charts 7-11) should be
noted.
Further evidence is provided by infrared spectra, Figure 17, of
extracts from the sediment samples compared with weathered Talco and
I/ Talco Crude Oil was used in this discussion to illustrate the
effects of weathering on Crude Oil. No implication is made that
CORCO or Union Carbide used Talco Crude Oil as a raw material.

Lenoa crude oils. The infrared spectra of extracts from the sediment
samples exhibit absorption bands that are typical of petroleum. Figure 17
shows a comparison of the spectra of the sediment extracts to known
weathered crude oils. Note the strong hydrocarbon bands at the 1300
cm"1 to 1400 cm"1 region and the 2800 cm to 3000 cm" region. Charts
1 through 4 exhibit the typical aromatic bands at 810 cm'1, 1600 cm
and 3050 cm . (The aromatic bands are not evident in charts 5
through 8 since these extracts were less concentrated). (26)
Organic Carbon
The distribution of organic carbon (OC) in Tallaboa Bay and Guaya-
nilla Bay sediment is shown in Figure 18. Highest OC sediment concen-
trations were found along Guayanilla Point in Tallaboa Bay (maximum OC
concentration 5.3 percent percent at station TB-7). The OC concentration
gradients decreased to the east and south in Tallaboa Bay, consistent with
current patterns (Figure 2).
Nitrogen and Phosphorous
The highest sediment organic nitrogen (ON) concentrations, Figure 19,
were found in Tallaboa Bay near the CORCO (the major source of ammonia
and total Kjeldahl nitrogen) and Union Carbide waste outfalls. The OH
concentration gradients decreased to the east and southward out of
Tallaboa Bay. The sediment ON serves as a reservoir of nitrogen for the
ecosystem.
Sediment total phosphorus concentrations ranged from 0.03 percent to
0.22 percent in Tallaboa Bay sediment and 0.10 percent to 0.28 percent
in Guayanilla Bay sediment. Total phosphorus concentrations were lower
at the moat easterly station in Tallaboa Bay 0.03 percent at TB-2) and

the most westerly station used in the study (0.10 percent at GB-15).
The highest sediment phosphorus concentrations were found in sediment
immediately adjacent to the three rivers (Guayanilla Tallaboa and Yauco)
and probably result from municipal wastes discharged to these rivers and
natural surface water runoff.
Metals
Thirty-one of the sediment samples were analyzed for mercury (dry
weight basis). The highest concentration, 0.31 mg/kg, occurred at sampling
station TB-7. Mercury concentrations ranged from less than 0.05 to 0.31
mg/kg in Tallaboa Bay sediment and from less than 0.06 to 0.13 mg/kg in
Guayanilla Bay. These sediment mercury concentrations do not suggest
a significant accumulation of mercury in the sediment of either Bay.
Six of the sediment samples were subject to emission spectrographic
analyses. Metals detected in sediment samples in concentrations above the
detection limit of the analyses included iron, manganese, aluminum,
barium, and strontium. One sediment sample, TB-7, contained 150 mg/kg of
copper. This sample suggests that copper is being accumulated in Tallaboa
Bay sediment. However, more sediment sampling would be required to confirm
this accumulation.
BIOLOGICAL STUDIES
Benthic macroinvertebrates, plankton, and periphyton were collected
and analyzed according to the methods described in Appendix E.
These studies showed that petrochemical wastes discharged into
Tallaboa Bay had a damaging effect as shown by:
o Reduction in the standing crop and diversity of the
community of macroinvertebrate organisms inhabiting the
-------
43
two bays.
t Deterioration of the substrate and destruction of corals
by the deposition of oil and detritus in western Tallaboa
Bay.
• Proliferation of unsightly nuisance growths of filamentous
green algae of the genera Cladophora and Enteromorpha
along the shorelines of the bays.
Dredge Samples
Stations sampled with the Petersen dredge in both Tallaboa and
Guayanilla bays (foldout map) supported low standing crops of benthic
macroinvertebrates. Macroinvertebrates ranging from means of 2 to 31
organisms per square foot and 5 to 27 organisms per square foot were
observed in Tallaboa Bay and Guayanilla Bay respectively (Table 7).
Nearshore sampling stations in Tallaboa Bay (TB-6 and TB-7), directly
in the line of movement of wastes from the Corco and Union Carbide
effluent canals, supported the lowest standing crops of the eight
stations sampled.
The standing crop of macroinvertebrates in Guayanilla Bay was lowest
at interior stations (GB 11, 12, and 13) near the loading docks and
discharge canals, where it was comparable to the lowest standing crops
of macroinvertebrates found in western Tallaboa Bay (Table 7).
Artificial Substrate Samples
Artificial substrate samples, as described in Appendix E, were
incubated insitu for one month at two stations in Tallaboa Bay remote

from the effluent canals (TB-1 and TB-2) and at two stations adjacent
to the canals and/or in the line of movement of wastes from the canals
(TB-3 and TB-7).
On the basis of identification of the major taxonomic groups
shown in Table 8, there were considerably fewer taxa at Station TB-7,
which is directly in the line of effluent movement, than at the other
stations sampled.
Underwater Observations
With the aid of SCUBA, four underwater transects were observed,
and numerous spot checks were made throughout Tallaboa Bay (transects
1 to 6, foldout map). The observed effects of waste discharges from
Corco and Union Carbide on the bay substrate are summarized below:
Transect Damage to Environment
1 Oily sand, dead coral
2 Dead coral, patch reefs encumbered with
detrital sedimentation
3 No effects
4 Light to heavy oil deposits
5 & 6 Vegetation limited to Cladophora and
Enteromorpha, no live mollusks.
Similar effects were observed by Patrick (27) in Yabucoa Bay,
which is east of Tallaboa Bay and also receives petroleum wastes.
Patrick said of the corals:

"There are many areas, especially alpng the Inside
margins, where the corals are dead or dying, and many
are encumbered by algae and other marine growth."
Phytoplankton
A total of 66 grab samples were examined for phytoplankton.
This sampling represented two days of surface collection at 15
stations and two days of collection at six stations (three depths).
Each station was sampled once during ebb slack and once on flood slack
tide.
The total phytoplankton counts (surface collection) ranged from
891 cells per milliliter (ml) at TB-1 to 66 cells /ml at GB-15
(Tables 9 and 10 and Figure 20). Total counts were appreciably higher
in Tallaboa Bay than in Guayanilla Bay on both collection dates. The
higher total counts of algae in Tallaboa Bay were primarily the result
of the abundance of filamentous green algae of the genera Cladophora
and Enteromorpha. Both of these genera characteristically grow in
great abundance in waters enriched with decomposable organic wastes.
Enteromorpha has been considered an indicator of marine and estuarine
pollution (28). Dense mats of both Cladophora and Enteromorpha were
present along the shores and docks of both bays.

APPENDIX B
PROJECT OUTLINE
INDUSTRIAL WASTE MONITORING
Industrial waste sampling was limited to the waste discharges of
Commonwealth Oil and Refining Company (CORCO) and Union Carbide Caribe.
Four sampling points were used:
• CORCO submerged outfall (CORCO 19)
• Union Carbide seawater cooling water intake (UCC 20)
• Union Carbide main effluent canal (UCC 21)
• CORCO main refinery and petrochemical waste effluent
canal (CORCO 22)
Nine 24-hour composite samples were collected at each sampling
point with automatic compositing samplers. These samples were analyzed
for BOD5, TOG, Cl, pH, alkalinity or acidity, TO, NH3, N03-N02, total
and ortho phosphorous, suspended and volatile suspended solids, sulfide,
phenol and cyanide.
A master composite of the nine daily waste composites was made for
each sampling point. The master composites for each sampling point were
analyzed for organic compounds^' and heavy metals.
Grab samples were collected for DO, temperature, and oil and grease
analyses.
I/ Since no single compound was found in concentrations higher than the
microgram per liter range, no attempt was made to identify specific
organic compounds.
-------
B-2
WATER QUALITY
Routine Water Quality
Routine water quality samples were collected six times during the
2/
study — three sets at flood slack ~~ and three sets at ebb slack
tide. Samples were collected with Kemmerer samplers at surface (1 foot
depth) and bottom (1 foot from bottom) locations at eight stations
in Tallaboa Bay and seven stations in Guayanilla Bay. Samples were
analyzed for: DO, temperature, chloride, pH, TOG, BODr, TKN, ammonia
nitrate-nitrite nitrogen, total and ortho phosphate, and turbidity.
Diurnal DO Studies
Two diurnal dissolved oxygen studies were made at five stations
in Tallaboa Bay and three stations in Guayanilla Bay. Samples were
collected for DO, Cl and temperature analyses at three to four-hour
intervals at each station from just before sunrise to just after sun-
set.
Special Water Quality
A special water quality study was made March 19, 1971. Surface
samples were collected in sample bottles from three stations in Tallaboa
Bay and three stations in Guayanilla Bay. Samples were collected at
high and low water slack tide and composited for heavy metal and organic
characterization analyses.
Sediment Characterization
Sediment samples were collected with a Petersen dredge at 15 routine
2/ Referenced to predicted tides at Playa de Ponce.
-------
B-3
water quality stations and 22 special stations in the bays. These samples
were analyzed for organic carbon, organic nitrogen and total phosphorus
and mercury. Six of these samples were analyzed for heavy metals and
organic characterization. Eleven sediment samples were analyzed for
oil and grease.
Guayanilla Bay Temperature Profiles
A special temperature study was made in Guayanilla Bay on March 13,
1971 to trace the heated effluent from the South Coast Steam Plant.
Temperature measurements were made with an electronic thermometer at
surface, six inch, one foot locations and every two feet thereafter at
20 locations in Guayanilla Bay.
BIOLOGY
Benthos
Seven Petersen dredge hauls were taken at each of the fifteen sta-
tions in the study area. Substrate for each station was generally
described and benthic organisms were enumerated and identified. Artifi-
cial substrates were placed at four stations and exposed for 31 days.
Organisms were collected from them counted and identified.
Periphyton
Artificial substrates were placed at seven stations and exposed for
28 to 31 days. These were analyzed for total periphyton counts and ash-
free dry weights.
-------
B-4
Plankton
Plankton samples were collected at fifteen stations from surface
(one foot depth) locations once during ebb and once during flood tidal
conditions. These were analyzed for total plankton counts. Primary
productivity was determined at six stations using the light and dark
bottle technique. Analyses were conducted once during ebb and once
during flood conditions. Secchi disc readings were taken and the
euphotic zone determined. The DO and plankton samples were collected
from three depths within the euphotic zone and analyzed.
Vascular Plants
Vegetation was collected at selected areas, identified and noted
as to general abundance.
Scuba Observations
Underwater observations were made of plants, animals, and benthic
substrates.

Appendix E
BIOLOGICAL METHODS
ARTIFICIAL SUBSTRATES
Artificial substrates which were made of 7" x 11" cylindrical
metal barbeque baskets filled with l"-2" diameter rocks were placed
on the bottom, with the exception of Station TB-7, where the baskets
were suspended six feet off the bottom due to the soft bottom. Two
substrates were used at each station and left in place for four weeks.
The artificial substrates were removed by SCUBA divers. The organisms
were preserved in enough formalin to provide a 5 percent solution and
returned to the laboratory for counting and identification.
BENTHIC SAMPLES
Benthic samples were taken with a Petersen dredge. Samples were
washed in a #30 sieve. The washed material was placed in a white enamel
pan and the organisms removed. The, organisms were preserved in formalin
and returned to the laboratory for identification.
PERIPHYTON
Periphyton samplers consisted of a plexiglas rack holding five
25mm x 75mm glass microscope slides. The plexiglass racks were placed
with the artificial rock substrates near the bottom at stations TB-1,
TB-2, TB-3, and TB-7. The remaining periphyton samplers were attached
approximately 10-15 feet below the surface of the chains holding buoys
at stations TB-4, GB-9 and GB-10.
-------
E-2
The glass slides were removed after maximum exposure, 28-31 days.
Four of the five slides were air dried for 24 hours and used for
obtaining biomass (ash-free weight). One slide was preserved in for-
malin and used in identifying and quantifying the periphyton.
Ash-free weights were obtained by removing the material from the
slides, drying to a constant weight at 105°C, and igniting for one
hour at 500°C. The ash was rewetted with distilled water and brought
o
to a constant weight at 105 C. The mean weights from the several
slides were calculated and reported as grams dry weight and ash-free
weight per square meter of exposed surface.
The periphyton on the slide preserved in formalin was removed
and dispersed in the 100 milliliters of preservative. A one milliliter
aliquot was transferred to a Sedgwick-Rafter cell and a strip count
2
made. The counts were expressed as cells per square millimeter (mm )
of substrate area.
PLANKTON
Each plankton station was sampled twice, once during ebb tide and
once on a flood tide. Samples were taken at a one-foot depth with a
Kemmerer sampler. All plankton samples were preserved in formalin.
For the laboratory analysis of the quantitative plankton samples, a
one milliliter aliquot was taken from each well-mixed sample, placed in
a Sedgwick-Rafter counting cell and checked for plankton under 200x
magnification. Two "strip counts" were made from the cell as plankton
were identified, enumerated, and recorded into major groups.
-------
E-3
Primary Productivity
Primary productivity was studied using the dissolved oxygen (light
and dark bottle) technique.— Productivity was measured twice; once on
ebb tide and once on a flood tide for six hours. Productivity samples
were taken from surface, depth, and at the one percent light transmission
level. If the bottom was reached before the one percent light penetration
level was reached, the productivity sample was taken approximately one
foot from the bottom. Light penetration was measured by means of a
secchi disc. Plankton samples were collected at each depth.
