                             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

* 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

                             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

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.

                             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.

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

 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-

                        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

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

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.

     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

 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

discharge molybdenum in small quantities.  Neither industry discharges



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

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

-------
                                                                     39
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:

             community of macroinvertebrate organisms  inhabiting the

                            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).

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.

                    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.

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.

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.

                        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.
