                          I. INTRODUCTION




     The Chesapeake Field Station of the Middle Atlantic Region,




FWPCA, conducted a field survey of water quality in the Northeast



River, Elk River, C & D Canal, Bohemia River, Sassafras River



and the upper Chesapeake Bay in late summer 1968.




     The objectives of these cruises were to:



     1. assess water quality in these waters;



     2. estimate standing crops of phytoplankton and observe areas



of rooted aquatic plants in the tributaries under summer low flow



conditionsj



     3. evaluate, under field conditions, a Yellow Springs



Instrument Company portable dissolved oxygen meter.



     The parameters measured were:



     Temperature



     Salinity




     PH



     Light extinction, secchi disk



     Dissolved oxygen (field meter and Winkler titrations)



     Biochemical oxygen demand



     Total phosphorus



     Total Kjeldahl nitrogen



     Oxidized nitrogen (N02 + NO,)



     Chlorophyll a



     Turbidity



     Phytoplankton populations

-------

-------
                           II PROCEDURES








A.   Sampling and field observations



     Temperature was measured in situ with a TSI thermistor which



was integral with the 50' in situ dissolved oxygen probe.



     One gallon samples were retrived from just below the surface



and at one intermediate depth (usually lŁ') by means of a submers-



ed 12 volt modified bilge pump with plastic impeller and housing,



connected with V garden hose to the boat.  The final orifice of



the garden hose was modified with reducing adapters to accomodate



^" tubing for filling of conventional 300 ml oxygen bottles.



     pH was determined aboard the vessel with a Beckman N-l meter,



from an aliquot of the gallon sample.



     The gallon samples were iced in portable coolers and returned



to the laboratory at Annapolis for further analyses.








B.   Chemical analyses



     1.  Dissolved oxygen was determined by the azide modification



of the Winkler method on samples fixed in the field, and titrated



potentiometrically at the laboratory in Annapolis with a Fisher



automatic "Titralyzer".  (Reference:  Standard Methods for the



Examination of Water and Wastewater, 12th ed. 1965)



     In situ oxygen determinations were also made with the Yellow



Springs Instrument Company Model J&RC portable dissolved oxygen



meter.  The probe was calibrated at each station by the empirical



values of dissolved oxygen in saturated air supplied with the



instructions for the instrument.



     2.  Biochemical Oxygen Demand was determined, with no dilutions



or seeding, by the procedure outlined in Standard Methods.  One



initial D.O. and duplicate final 5 day D.O. determinations were made,



with the Winkler titrations as cited above.



     3.  Turbidity was determined with a Hach photoelectric



nephelometer, calibrated in Jackson Turbidity Units.



     k-  Salinity was determined with calibrated hydrometers.



     5.  Light extinction, in inches, was made with a 12" (30 cm)



white Secchi disk.

-------

-------
     6.  Total phosphorus (expressed as mg/1 PO^) was determined by



the persulfate procedure described by D.W. Menzel and N. Corwin



("The Measurement of Total Phosphorus In Sea Water Based on the



Liberation of Organically Bound Fractions by Persulfate Oxidation",



Limnology and Oceanography 10:280-282, 1965.)



     Phosphate was measured colorimetrically with the procedure out-



lined by J. Murphy and J. P. Riley ("A Modified Single Solution



Method for the Determination of Phosphate in Natural Waters",



Analytica Chimica Acta, 2^:31-36, 1962.)



     7.  Oxidized nitrogen (NOj+NOo), expressed as NO.,-N, was



determined by the Cd-Cu reduction column as described by E.D. Wood,



F. A. J, Armstrong and F. A. Richards ("Determination of Nitrate in



Sea Water by Cadmium-Copper Reduction to Nitrite", J. Marine



Biological Assoc. U. K. Itf:23-31, 1967.)



     8.  Total Kjeldahl Nitrogen (TKN) was determined by the procedure



outlined in Standard Methods.  This method included NH,-N in the results.



     9.  Chlorophyll a was determined by extraction of Millipore-



filtered samples in 90$ acetone and read spectrophotometrically, as



outlined by Strickland and Parsons ("A Manual of Sea Water Analysis",



2nd edition, revised, Fisheries Research Board of Canada, Bulletin




125, Ottawa, 1965.)



    10.  Phytoplankton populations were identified and counted in a



Sedgwick-Rafter counting chamber.  Diversity indices were calculated



by a method described by R. Margalef "Temporal Succession and Spatial



Heterogeneity in Phytoplankton" in Perspectives in Marine Biology



edited by Buzzatti-Traverse, University of California Press,



Berkeley, 1958.

                         CRUISE NARRATIVE








    August 27, 1968 - Wind was NW, 2-ii mph at start of cruise.



Tide was very low.  Previous night had been the first com-



paratively cool night after a 10-day hot spell.



    The Sassafras River at Georgetown was green with algae,



like split-pea soup, especially in the shallower waters.



This scum of blue-green algae was no longer evident at Station 2.



    Wind increased to 15-20 mph, Bay was rough.



    Many clumps of wild celery (Vallisneria) adrift in the mouth



of the Elk River by Turkey Point.




    In the Bohemia River, stringy, slimy green algae (Spirogyra)



were evident at both stations.  Scotchman's Creek had exceptionally



clear water, with all details of the bottom clearly definable



in 3 feet of water, in contrast to all other areas of the cruise.



    Waters in the C & D Canal were a peculiar gray color, in



contrast to the obvious green color throughout the cruise.



    Conversation with a marina operator by Station 13 in Elk



River indicated severe bloom conditions had existed in previous



two weeks, but was much Improved at time of visit.

 A0    Purpose aJid  Scope




      During the year  of  1967,  the Chesapeake  Technical  Support




 Laboratory, Middle  Atlantic  Region,  Federal Water  Pollution




 Control Administration conducted three  separate  surveys on the




 estuary portion of  the Potomac River„   These  surveys were conduct-




 ed to determine existing  water quality„   The  results of these




 investigations are  presented in tnis report0




 Bo   General Remarks




     An intensive bacteriological and total phosphorus  water




 quality survey was  conducted on the  estuary during the  weeks of




 March 2 thru llu  A two-day  intensive nutrient water quality




 study was conducted September 20-^1»  During  the weeks  of




 February 3 thru 21  an intensive bacteriological survey  was conduct-




 ed of four sewage treatment  plants discharging in  the Potomac




 estuary.




 Co   Sampling Procedures




     Surface samples for  chemical analysis were obtained by




 dipping a plastic bucket  or  large funnel into the  river water




with a minimum of agitation.  Samples were retained in  plastic




 one-gallon ncubitainers0"  Dissolved oxygen (DO) samples were




 obtained by siphoning from the bucket or by attaching a tube to

-------
 the  funnel  outlet  and extending it  to the bottom of a




 conventional  300 ml  DO bottle«   The bottle was  overfilled  twice




 without  excessive  agitation,  and the  DO fixed immediately,,




 Temperature was measured  in the dipped bucket immediately




 after  sampling»




     Bottom samples  were  taken  using  a plastic  Van Dorn samplert




 Sampling procedures  were  otherwise  identical to those used for




 surface  samples0   All samples were  stored on icea   Analysis




 was  started immediately on return to  the Chesapeake Technical




 Support  Laboratory,  generally within  two hours  of samplinge




     All bacteriological  samples were obtained  by dipping  a




 sterile  sample bottle directly  into the stream0   The  full




 bacteriological sample bottle was then capped and  iced0




 Analysis was  started immediately on return to an on the  spot



 mobile laboratory,,




 Do   Measured Parameters  and Analytical Methods




     1<>  Water temperature was  determined using  a  mercury



 thermometer inserted into the sample  container  immediately




 upon collections




     20  Light extinction, in inches,  was made with a 12"




 (30 cm)  white Secchi disko

Water and Wastewater,  12  edc,

-------
          Dissolved  Oxygen was  determined by the azide



modification of the basic Winkler method with the titration




done  potentiometrically with an automatic "titralyzer0"

Waterso   Analytica  Chimica Acta,  27:   31-360




          Total  Phosphate was determined after  persulfate



oxidation of the  sample in an  autoclave at  1|?  psi for 30




minuteso  The resultant ortho-phosphate was then determined




colorimetrically as  the molybdenum-blue complex with the



optical density measured at  882 mjAe

     60  Total Kjeldahl Nitrogen




         Reference:  Standard Methods for the Examination of




Water and Wastewater, 12 ede, 1965.



         Total Kjeldahl Nitrogen includes ammonia and organic




nitrogen and was determined by the standard micro-kjeldahl




procedure o  The sample was digested in the presence of strong




acid to convert the organic nitrogen to ammonia0  The ammonia




was then distilled, collected in boric acid solution,




nesslerized and determined colorimetrically0




     7.  Nitrate + Nitrite




         Reference:  A Manual of Sea Water Analysis, J.D.H.




Strickland and T.R. Parsons, 2nd0 ed., Queen's Printer and




Cotroller of Stationery, Ottawa, Canada, 1965.




         Nitrate plus Nitrite nitrogen was determined by



the cadmium reduction of nitrate to nitrite and subsequent




diazotiaation with sulphanil amide and N-(l-napthyl)-




ethylenediamine dihydrochlorideo  The results were calculated



as nitrite nitrogen.




     8.  Chlorides




         Reference:  Fisher Scientific Company, Bulletin
         The Chloride concentration was determined by



titrating the sample with standard silver nitrate to a

-------

-------
potentiometric end point using a silver indicating electrode




and a silver/silver chloride reference electrode.




     9.  Chlorophyll



         Reference:  A Manual of Sea Water Analysis, J»D.H0




Strickland and T.R. Parsons, 2nd. ed., Queen's Printer and




Controller of Stationery, Ottawa, Canada, 1965.




         Chlorophyll a was determined by extraction of




millipore-filtered samples in 90$ acetone and read




spectrophotometrically.




    10.  Turbidity




         Turbidity was determined with a Hach photoelectric




nephelometer, calibrated in Jackson Turbidity Units.




    11o  Coliform




         Reference:  Standard Methods for the Examination of




Water and Wastewater, 12 ed., 1965.




         Coliform population was determined using the 5 tube-




3 dilution Multiple-Tube Fermentation Technique0  Lauryl




sulfate tryptose broth was used for the presumptive test with



incubation at 35" * 0.5°C.  Brilliant green lactose bile broth




was used for the confirmatory test with incubation at 35° ^ 0<,




The results were reported as the Most Probable Number (MPN)e

^°   Purpose and Scope



     During the year  of 1968 the Chesapeake  Technical  Support




Laboratory, Middle Atlantic  Region, Federal  Water  Pollution




Control Administration conducted a monthly survey  of the




estuary portion of the Potomac River and one intensive during




the summer,,  This was done to determine  existing water quality.




The results of these  investigations are  presented  in this report.




Bo   General Remarks




     The monthly nutrient survey was conducted from May through




December and a three-day bacteriological and nutrient  intensive




was made August 20-22.  The  intensive survey included  examination




of effluent and influent water of ten sewage treatment plants




discharging into the Potomac  estuary.  A special nutrient run




was made on September llth of the lower part of the Potomac



River from the Route 301 Potomac River Bridge to Point Lookout.



Co   Sampling Procedure?




     Surface samples for chemical analysis were obtained by




dipping a plastic bucket or large funnel into the river water




with a minimum of agitation*,  Samples were retained in plastic




one-gallon "cubitainers."  Dissolved oxygen  (DO) samples were




obtained by siphoning from the bucket or by  attaching  a tube to

-------

-------
the funnel outlet and extending it to the bottom of a




conventional 300 ml DO bottle„  The bottle was overfilled twice




without excessive agitation, and the DO fixed immediately.




Temperature was measured in the dipped bucket immediately




after sampling.




     Bottom samples were taken using a plastic Van Dorn sampler,,




Sampling procedures were otherwise identical to those used for




surface samples.  All samples were stored on ice»  Analysis




was started immediately on return to the Chesapeake Technical




Support Laboratory, generally within two hours of sampling«




     All bacteriological samples were obtained by dipping a




sterile sample bottle directly into the stream0  The full




bacteriological sample bottle was then capped and icedo




D.   Measured Parameters and Analytical Methods




     10  Water temperature was determined using a Salinometer




during the intensive survey.  A mercury thermometer was used



at all other times inserted into the sample container immediately



upon collection.




     20  Light extinction, in inches, was made with a 12"




(30 cm) white Secchi disk0




     3.  pH




         The pH measurements were made with a field pH meter0

         Dissolved Oxygen was determined by the azide




modification of the basic Winkler method with the titration




done potentiometrically with a Fisher automatic "titralyzer."




     5o  Biochemical Oxygen Demand




         Reference:  Standard Methods for the Examination of




Water and Wastewater, 12 ed., 1965.




         The Biochemical Oxygen Demand was determined by the




azide modification of the basic Winkler method with the




titration done potentiometrically with a Fisher automatic




"titralyzer."  The samples as received were diluted if




necessary and transferred to standard 300 ml BOD bottles in




triplicateo  One initial DO and two final DO determinations




were used throughout,,  Incubation was started immediately at



20CC and continued for five days after which they were titrated.

Waters,,  Analytica Chimica Acta,  27:   31-36.



         Total Phosphorus  was  determined after persulfate




oxidation  of  the sample in an  autoclave  at 1% psi for 30




minutes.   The resultant ortho-phosphate  was then determined




colorimetrically as  the molybdenum-blue  complex with the




optical density  measured at  882 mp.<>




     7o  Total Kjeldahl Nitrogen




         Reference:  Standard  Methods for the Examination of




Water and  Waste-water, 12 ede,  196Ł0




         Total Kjeldahl Nitrogen  includes ammonia and organic




nitrogen and  was determined  by the standard micro-kjeldahl




procedureo  The  sample  was digested in the presence of strong




acid to convert  the  organic  nitrogen  to  ammonia.   The ammonia




was then distilled,  collected  in  boric acid solution,




nesslerized and  determined colorimetrically.



     8.  Nitrate  + Nitrite



         Reference:  A  Manual  of  Sea  Water Analysis,  J.D»H.




Strickland and T.R.  Parsons, 2nd. ed., Queen's  Printer and




Controller of Stationery,  Ottawa, Canada,  1965°




         Nitrate plus Nitrite  nitrogen was determined by




the cadmium reduction of nitrate  to nitrite and  subsequent




diazotization with sulphanilamide and  N-(l-napthyl)-




ethylenediamine dihydrochloride.  The  results were  calculated




as nitrite nitrogen.

     13.  Nonfiltrable Residue



          Reference:  Standard Methods for the Examination  of



Water and Wastewater, 12 ed., 1965.



          The Nonfiltrable Residue was determined by filtering



a known volume of sample.  A predried and weighed Gelman



Type A glass fiber filter was used.  The filter and its contents



were then dried in an oven at 105*C, cooled and reweighed.



The gain in weight represents Nonfiltrable Residue.

                       I  INTRODUCTION






A.  Purpose and Scope




    From October 1966  through April 196? the Chesapeake Technical




Support Laboratory, Middle Atlantic Region, Federal Water Pollution




Control Administration received a weekly composite water sample




from thirteen wastewater treatment plants.




B.  General fteraarks




    This intensive survey included the examination of effluent and




influent water of sewage treatment plants discharging into the Potomac




River Basin.  Pertainent flow data was obtained from plant operation




records.




C.  Sampling Procedure




    Two plastic cubitaniers, one marked E and one marked I containing




5> cc chloroform, were  capped and sent to each treatment plant weekly.




Instructions were included to add 100 ml daily, reseal and return to our



laboratory by mail.




D.  Measured Parameters and Analytical Methods



    1.  Total Phosphorus




        Reference:   Menzel,  D.„. and Corwin, N. 1965.  The Measurement




of Total Phosphorus in Seawater Based on the Liberation of Organically




Bound Fractions by Persulfate Oxidation.  Limonology and Oceanography,



10:   280-282.

                                                                    2
       Murphy,  J.  and Riley,  J.P.,  1962.   A Modified  Single  Solution




Method for  the  Determination  of Phosphate  in  Natural  Waters.   Analytica




Chimica  Acta, 2?:   31-36.




       Total Phosphorus was determined  after  persulfate  oxidation of




the  sample  in an autoclave at 15 psi  for 30 minutes.   The  resultant




ortho-phosphate was  then determined colorimetrically  as  the molybdenum-




blue complex with  the optical density measured at 882 mfj,.




     ?.  Nitrate Nitrogen




         Reference:   Standard  Methods  for the  Examination of Water and




Wastewater, 1? ed.,  1965.




         Jenkins, D.  and M?dsker, L.L.,  1961i<,  Brucine Method  for  Deter-




mination of Nitrate  in Ocean,  Estuarine, and  Fresh Waters..  Analytical




Chemistry,  36: 610-612.




         Nitrate nitrogen was  determined by the Jenkins modification of




the standard brucine  method.   The procedure includes  the masking  of




varying  chloride concentrations by  the  addition of excess  sodium




chloride.   The results were calculated  as  nitrate nitrogen.




     3.  Nitrite Nitrogen




         Reference:  Standard Methods  for the  Examination of Water and




Wastewater, 12 ed., 1965.




        A Manual of Sea Water Analysis, J.D.H. Strickland  and  T.R0




Parsons,  2nd. ed., Queen's Printer and  Controller of Stationery,  Ottawa,




Canada,  1965.

-------
                                                                 3






       Nitrite nitrogen was determined by diazotization with  sulfani-




lamide and N-(l-naphtyl)- ethylenediamine dihydrochloride0  The results




were calculated as nitrite nitrogen,,




     k* Total Kjeldahl Nitrogen




        Reference:  Standard Methods for the Examination of Water and




Wastewater, 12 ed., 1965.




        Total Kjeldahl Nitrogen includes ammonia and organic  nitrogen




and was determined by the standard micro-kjeldahl procedure,.  The




sample was digested in the presence of strong acid to convert the




organic nitrogen to ammonia.  The ammonia was then distilled, col-




lected in boric acid solution, nesslerized and determined colorimet-




rically.




     5>o  Flows




         Flow rates on data tables are as reported from wastewater




treatment plants (GPD, GPM or MGD)0

 500 yards above the dredge by the use of landmarks and U. S. C'^ast and




 Geodetic Survey chart No. 572.  Transects below the dredge were likewise




upprcxineted ^00 yards apart, by visual landmarks.   Surface and lf> f> u*




samples were retrieved at each of five stations on each 1 ranseci  in




sterile sample bottles, iced and returned to the laboratory at Annapolis




for bacteriological analysis and turbidity determinations.




     '.he sampling run was started at  1300 and finished at 14--5 hours SEE .




     The tide was ebbing while sampling.  Wind was from the south, 1C to




?0 miles per hour,  ar.d the water surface choppy.  There had been no




precipitation during the previous 48  hours.

-------
IABORATORY ESOCEDURE:






     ': ;J,al bacterial population densities were ectirra-t ed as plate counts




on Difco Plate Count agar (Standard Methods Agar).  Sinoe ihic area is




a region of relatively low salinity, all media were made wiih die-tilled




water rather than with water from the environment.  The pour plate method




was used, plates inverted and incubated for kk bours ai  20°C, then counted




with a Quebec colony counter.




     Culiforms and fecal coliforms were estirated wiih  the 5 t ube-3 dilution




MPN technique as out lined in Standard Methods (1965).




     water samples were analyzed for turbidity using a  liach nephclow* ric




photoelectric turbidimeter.   Results are expressed in Jackson ^urbidlty




uni's (JTU).



     Resulting data are shovn in Table 1.

     If it can be assumed that  the  elevated turbidiiy reudin^c wer^ due

                        I.  INTRODUCTION






A.  Purpose 'and*'Scope



    During the summer of 1967, the Chesapeake Support Laboratory,




Middle Atlantic Region, Federal Water Pollution Control Administra-




tion conducted investigations to obtain background water quality




information in the major river basins, and three smaller areas,




of the eastern shore of Chesapeake Bay (Delaware, Maryland and




Virginia).  The results of these investigations are presented




in this report.




B.  General Remarks




    Intensive water quality surveys were conducted on the Wicomico




River during the weeks of August 7-11 and August 21-25.  An




intensive water quality survey was conducted on the Pocomoke




River during the period July 2k to August 1.  A bathymetric




survey was subsequently conducted to obtain measurements of




channel volumes and cross-sectional areas, the data from which



are to be published separately.  Reconnaissance surveys were



conducted on the Nanticoke River and on the Wicomico and




Pocomoke Rivers prior to the intensive surveys.  Pollution




control surveys were conducted on Bunting Branch and Marshall




Creek.   A special bacteriological survey was conducted of




Chincoteague Bay shellfish holding waters.

-------

-------
    The purpose and conduct of the individual surveys varied




considerably; consequently the parameters measured differed




among  surveys.  It is necessary to look in data tables to




determine what parameters were measured at which locations.




All parameters measured during the 196? Eastern Shore Surveys




and methods used are lised in part D.




C.  Sampling Procedures




    Surface samples for chemical analysis were obtained by




dipping a plastic bucket or large funnel into the river




water with a minimum of agitation   Samples were retained in




plastic one-gallon "cubitainers."  Dissolved oxygen (DO)




samples were obtained by siphoning from the bucket or by




attaching a tube to the funnel outlet and extending it




to the bottom of a conventional 300 ml DO bottle.   The




bottle was overfilled twice without excessive agitation, and




the DO fixed immediately.   Temperature was measured in the




dipped bucket immediately after sampling.




    Mid-depth samples were taken using a plastic Van Dorn




sampler.  Sampling procedures were otherwise identical to




those used for surface samples   All samples were stored on




ice.   Analysis was started immediately on return to the




laboratory, generally within two hours of sampling.

                                                              3



 D.  Measured Parameters  and Analytical Methods




    1.  Water  temperature was determined using a mercury




 thermometer inserted  into the sample container immediately



 upon  collection.




    2.  Light  extinction, in inches, was made with a 12"




 (30 cm) white  Secchi  disk.




    3-  Salinity was  determined with a calibrated saliniometer.




    k.  Dissolved Oxygen




        Reference:  Standard Methods for the Examination of




 Water and Wastewater, 12 ed., 1965.




        Dissolved Oxygen was determined by the azide




 modification of the basic Winkler method with the titration




 done potentiometrically with an automatic "titralyzer."




    5.  Biochemical Oxygen Demand




        Reference:  Standard Methods for the Examination of




Water and Wastewater, 12 ed . 1965.



        The Biochemical Oxygen Demand was determined by the




 azide modification of the basic Winkler method with the



 titration done potentiometrically with an automatic




 "titralyzer."  The samples as received were diluted if




necessary and transferred to standard 300 ml BOD bottles in




triplicate.  One initial DO and two final DO determinations




were used throughout.   Incubation was started immediately at




20°C and continued for five days after which they were  titrated.

         Total  Phosphate  was  determined after  persulfate oxidation




 of the  sample  in an autoclave  at  15 psi for 30 minutes.  The




 resultant ortho-phosphate was  then determined colorimetrically




 as the  molybdenum-blue complex with the optical  density




 measured at 882  mjJ.0

         Reference:   Standard Methods for  the  Examination of




 Water and Wastewater, 12  ed0,  1965>°




         Total Kjeldahl Nitrogen includes  ammonia and organic



 nitrogen and was  determined  by the standard micro-kjeldahl



 procedure.   The  sample vas digested in the presence of strong



 acid to  convert  the  organic  nitrogen to ammonia.  The ammonia




 was then distilled,collected in boric  acid solution,




 nesslerized  and determined colorimetrically0

        Nitrate plus  Nitrite nitrogen was determined by




the cadmium reduction of nitrate  to nitrite  and  subsequent




diazoti'sation with  sulphanilamide and N-(l-napthyl)-




ethylenediamine dihydrochloride.  The results were calculated




as nitrite nitrogen.

                                  DATA REPORT






I.  PURPOSE




    In September 1969, the City of Richmond announced a proposal to




discharge approximately 3^ rogd of raw sewage to the James River for




11C -lays while connecting a new grit chamber to the sewage treatment




plant.  During October, the Federal Water Pollution Control Administra-




tion, Middle Atlantic Region conducted an intensive water quality




survey of the James River and selected tributaries to obtain information




''or evaluating any degradation from the raw sewage discharge and to




verify a math model of the estuary.




II. "COPE




    Seventeen stations on the James River, five on the Appomattox




Fiver, and one each on Falling Creek, Gillies Creek. Goode Creek, and




Almona Creek were sampled at either slack low or high tide from October l




through. October 30, for the following parameters:  temperature, D.O., BOD,




COD, total and fecal roliforms, nutrients, total organic carbon (TOC) ,




heavy metals. phytoplar.vton, volatile solids on oottom muds and bottom




fauna.




III. PROCEDURES




     All samp] ing and analyses were t>erformed in accordance with




either Gtandarc Methods for the Examination of Water and Wastewater




or FArPCA Methods for Chemical Analysis of Water and Wastes.

-------
                       I.  INTRODUCTION






        The Chesapeake Field Station of the Middle Atlantic Region,




Federal Water Pollution Control Administration,  conducted an intensive




survey of the North Branch Potomac River Basin between Bloomington




and Cumberland, Maryland, during August 196? (see Figure l).   The




purpose of this survey was to aid in verifying the model DO and




BOD parameters.  The survey should also show the extent of any




diurnal water quality fluctuations including the effects of mine




drainage.

-------
                        II.  PROCEDURE





    A.  Sampling




        All samples for chemical analysis were obtained by dipping




a plastic container full of the shallow stream water.  A quart




cubitainer was then filled from the dipped sample and iced.   A




portion of the dipped sample was siphoned into a DO bottle until




overflowing and fixed.  A portion of the dipped sample was also




used to measure the pH and temperature at the time of sampling.




The iced samples were returned to the camper laboratory within




two hours where the analyses were started immediately.

Water and Wastewater, 12 ed., 1965.




            Dissolved oxygen was determined by the azide modi-




fication of the basic Winkler method with the titration done




potentiometrically with an automatic TITRALYZER.




        2.  Biochemical Oxygen Demand




            Reference:  Standard Methods for the Examination of




Water and Wastewater, 12 ed., 1965.




            The biochemical oxygen demand was determined by the




azide modification of the basic Winkler method with the titration




done potentiometrically with an automatic TITRALYZER.  The samples,




as received, were diluted if necessary and transferred to standard




300 ml BOD bottles in triplicate.   One initial DO and two final

-------
DO determinations were used throughout.  Incubation was started




immediately at 20°C and continued for five days after which they




were titrated.





        3-  pH




            The pH measurements were made at the sampling point




with a field pH Meter.




        k.  Total Alkalinity




            Reference:  Standard Methods for the Examination of




Water and Wastewater, 12 ed., 1965.




            The total alkalinity was determined by titrating 100 ml,




or suitable aliquot, to pH 14-.5 with standardized 0.02 N sulfuric




acid.  A laboratory pH Meter was used to indicate pH changes.




        5.  Total Cold Acidity




            Reference:  Standard Methods for the Examination of




Water and Wastewater, 12 ed., 1965.




            The total cold acidity was determined by titrating



100 ml, or suitable aliquot, to pH 8.3 with standardized 0.02 N



sodium hydroxide.  A laboratory pH Meter was used to indicate pH




changes.

-------

-------
I.  INTRODUCTION




        The quality of waters surrounding and within the confines




of the Aberdeen Proving Ground, Department of the Army, has not




been determined in the past because of the security and safety




restrictions occasioned by the ordnance testing at this facility.




        A sampling program of these waters was undertaken during




the last quarter of 1967 by the Chesapeake Field Station (CFS)




as part of the Chesapeake Bay-Susquehanna River Basins Project




comprehensive program.  The Harford County Metropolitan Commis-




sion also requested water quality data specifically in Bush




River and Roraney Creek to estimate the effects on the receiving




waters (Romney Creek) of the Sod Run Sewage Treatment Plant




presently under construction.  In addition, the Engineering




Supply Services Division at the Aberdeen Proving Ground (APG)




was interested not only in the quality of the surrounding waters




but also in the effect of discharges from the activity's sewage




treatment plants on the receiving waters, in accordance with




Executive Order Wo. 11288 applying to Federal installations.

-------

-------
II.   PROCEDURE




         Since interruption of the daily ordnance testing program




 could not be allowed, it was necessary for the CFS to coordinate




 sampling with the safety and planning officers at the facility




 to make use of the early and midday hours when testing was not




 in progress.  Special security precautions were required while




 sampling was conducted in the range area:  1.  An APG staff




 representative was present at all times; and 2.  constant tele-




 phone or radiotelephone communication was maintained at all




 times.




         Since the CFS did not have radiotelephone equipment of




 suitable frequency and range on its boats, the cooperation and




 assistance of the Division of Marine Police, Maryland Department




 of Chesapeake Bay Affairs (MDCBA) were requested and received.




 A radiotelephone-equipped boat and skiff with operating personnel




 were made available to CFS sampling personnel for the duration




 of the survey.




         Most of the sampling in the restricted areas was completed




 during the early morning hours before ordnance testing began at




 8 A.M.  Some runs in critical areas were made during the midday




 recess.  Sampling outside the restricted area was generally




 conducted with CFS equipment later in the day, and all samples




 were returned each day to CFS for analysis.




         The survey extended from the mouth of the Susquehanna




 River (Station 1, Figure l) to the head of the Bush River Estu-




 ary (Station 20).  The special surveys included Romney Creek




 (Stations 11 to 15), Spesutie Narrows (Stations 7 to 9), Swan




 Creek (Stations 3 to 5 and SI to S5), and sewage treatment




 plant effluents in Swan Creek.

-------

-------
III.  DETAILED INVESTIGATION
          The primary purpose of the investigation vas to obtain

  water quality data along the northwest shore line of Chesapeake

  Bay and to investigate possible effects of treated waste dis-

  charges from Havre de Grace, Aberdeen, Aberdeen Proving Grounds,

  Ferryman, and Edgewood Arsenal on water quality in tributaries

  to the Bay.  The sampling stations selected and locations of

  sewage treatment plant outfalls are shown in Figure 1.   The

  samples were analyzed for salinity, temperature, turbidity, pK,

  Kjeldahl nitrogen, nitrites and nitrates, phosphorus, chloro-

  phyll, biochemical oxygen demand, dissolved oxygen, colifonns,

  and fecal colifonns.
          The investigation in Romney Creek was originally planned

  to determine existing water quality in a relatively undeveloped

  tidal creek into which effluent from the Sod Run Sewage Treatment

  Plant will be discharged.  This data could then furnish a back-

  ground for further study in waste assimilative capacity and

  "polishing" action in nutrient removal.  Since the terms of the

  easement granted by APG to the Harford County Metropolitan Com-

  mission require advanced waste treatment if nutrient levels are

  excessive, special emphasis was placed upon nutrient determinations.
          Subsequently, it was learned that the Baltimore Gas and

  Electric Company had acquired an adjacent acreage for a proposed

  thermal electric plant which would draw approximately 3,000 gpm

  from Bush River for cooling purposes and discharge the heated

  effluent into the headwaters of the Romney Creek tidal river.

  The utility company has prepared a hydrographic survey of Romney

  Creek which can be of value in further study of dilution poten-

  tial thermal and treated waste discharges.  Development of this

  electric power facility would obviously eliminate the "polishing

  pond" potential and transfer the problem area study to the adja-

  cent Chesapeake Bay area.

-------

-------
        Two additional special investigations were made at the




request of APG.  The first was to determine the effect of treated




discharges from the main APG sewage treatment plant upon the




receiving waters in Spesutie Narrows.




        The second investigation was to determine the effect of




treated effluent discharges from the APG Pusey Sewage Treatment




Plant on the receiving waters of Swan Creek.  This is a plant




providing an apparent adequate secondary treatment, but since




both the Glenn Heights and Town of Aberdeen sewage treatment




plants discharge into Swan Creek upstream, APG requested an




assessment of the relative pollution potential from their plant.

-------

                                                            5
IV.   FINDINGS
         Water quality standards used are those adopted by the

 State of Maryland Water Resources Regulation 4.8 and approved

 by the Secretary of the Interior.  These provide for water con-

 tact recreation in all waters tested (except for Romney Creek

 and Spesutie Narrows), with a fecal coliform count not to exceed

 2kO MPN per 100 ml unless a "detailed sanitary survey and evalua-

 tion discloses no significant public health risk in the use of

 the waters."  No bacterial standards were established for Romney

 p-rpoV m- Rrxasiit.i p l\is>T-rcTJc;.  sinos t.hey are entirelv within the

 restricted area at APG and are classified for industrial use

 only.
         A review of the appended tabulations of sample analyses

 will show several stations where fecal coliform counts signifi-

 cantly in excess of the standard would suggest a further sani-

 tary investigation.  The questionable stations and pertinent

 comments follow:
         Station 2, Buoy Can 13:  This sampling point is along a

 deep water channel south of the outfall of the Havre de Grace

 Sewage Treatment Plant which provides primary treatment only.
         Station 3. Swan Creek Headwaters:  This location is

 below the outfalls of the Pusey, Aberdeen, and Glenn Heights

 sewage treatment plants and suggests a possible source of the

 frequent high fecal coliform counts.  A special sampling run

 was made to include Stations SI to S5 between the sewage treat-

 ment plant, and the effluents at each plant were also sampled

 (Stations 21 to 23).  It should be noted that Stations SI and

 S2 are in the free-flowing reach of Swan Creek, as contrasted

 with Si* and S5 where tidal currents make identification of

 potential pollution sources less definite.  High chlorophyll

 values show the effects of the higher nutrient figures for

-------

-------
phosphates and Kjeldahl nitrogen and serve as an  indication that

any increase in these parameters could result in  excessive chlo-

rophylls.  The erratic high coliform counts in the effluent from

the Glenn Heights extended aeration plant could be evidence of

inadequate chlorination or slugs of high organic  sludge discharged.
        Stations 10, 11, 12, 13, lU, and_15, Romney Creek:

While the bacterial quality in this tidal creek is generally

good, the high fecal coliform counts in the headwaters suggest

that there are sources of inadequately treated wastes entering

upstream.  No bacterial standards have been established in

Roiniicy CrcŁii.; jL±c~wtvcr, J.L. &.J.-1 otiiti* rc^p^c'Co "otic  Wctucj." m'uao.i.L.j

must be considered good.  The nutrient levels in  these waters

can be called moderate, when compared to a figure of 0.1 mg/1

phosphorus (approximately equivalent to 0.3 mg/1  phosphate) that

is currently used as the maximum acceptable value without stimu-

lating excessive algal production.  While pH values are low,

they are of obvious natural occurrence.
        Stations T, 8, and 9, Spesutie Narrows:   Discharge from

the APG main sewage treatment plant at the head of this waterway

near Station 7  could  account for the high fecal coliform  counts.

Bacterial  quality is  progressively higher, until  the samples  at

Station 9  at the mouth meet Chesapeake Bay standards.  There

have been  no bacterial standards set for Spesutie Narrows.
        Stations 18 and 19, Bush River:  Occasional high  fecal

coliform counts at these stations suggest that a  detailed sani-

tary survey may be required before these waters can be considered

safe for water contact recreation.  The area is restricted, how-

ever, because of Department of the Army facilities at the adjacent

Edgewood Arsenal and Aberdeen Proving Grounds.  Further investi-

gation of  Edgewood Arsenal sewage treatment plant operations and

discharges in this area is proposed.

-------

V.  CONCLUSIONS




        In general the water quality in Chesapeake Bay, as




determined in this investigation, can be considered good.




Dissolved oxygen is high, pH values range from moderately high




in the northern area to somewhat low in the southerly and Bush




River areas.  The Bay is moderately rich in nutrients, but in




no areas investigated were they found to be excessive.




        More detailed, sanitary surveys are required in those




specific areas where questionable water quality was found.

I.    PURPOSE

     The purpose of this report is to disseminate data resulting

from several biological studies conducted in the Potomac River

Basin upstream from Great Falls, Maryland.  Studies on the North

Branch of the Potomac River and tributaries were specifically

designed to supplement the 'Interim Report-Mine Drainage Pollution

of North Branch of the Potomac River 1966-1968" and the report

on "Water Quality in the North Branch of the Potomac River

between Cumberland and Luke, Maryland."  Findings of these

studies plus other sampling efforts provide an insight into

the biological response of the aquatic environment to acid

mine drainage and organic pollution in selected stream reaches.

II.  SCOPE

     During the period 1966-68, a stream sampling program was

conducted to determine biological conditions in the Potomac

River Basin upstream from Washington, D. C.  The study area
                          *
consists of three distinct sub-basins of the Potomac River:

t'he entire North and South Branch drainages plus the main

stem of the Potomac River from Paw Paw, West Virginia,to Great

Falls, Maryland.

     For purposes of this report, the community of bottom

macro-organisms was selected as the indicator of the biological

conditions in the stream since they serve as the preferred

food source for higher aquatic forms and exhibit similar reac-

tions to adverse stream conditions.  Macro bottom organisms

are animals that live in direct association with the stream

bottom, and are visable with the unaided eye.  They are dis-

tinquished from micro organisms by the fact that they are re-

-------

-------
tained in a No. 30 mesh sieve.  The combination of limited




locomotion and life cycles of one year or more for most benthic




species provide a long-term indicator of stream water quality.




     Classification of organisms in this report is considered




in three categories:  pollution sensitive, intermediate and




pollution tolerant.  In unpolluted streams,a wide variety of




sensitive clean-water associated bottom organisms are normally




found.  Typical groups are stoneflies, mayflies, and caddis-




flies.  These sensitive organisms usually are not individually




abundant because of natural predation and competition for food




and space; however, the total count or number of organisms at




a given station may be high because of the different varieties




present.  Sensitive genera (kinds) tend to be eliminated by




adverse environmental conditions (e.g., chemical and/or physical)




resulting from wastes discharging into the stream.




     In waters enriched by organic wastes comparatively fewer




kinds of animals are found though great numbers of certain




genera may be present.  Organic pollution-tolerant forms such as




sludgeworms, rattailed maggots, cerJtain species of bloodworms




(red midges), certain leeches, and some species of air-breathing




snails may multiply and become abundant because of a favorable




habitat and food supply.  These organic pollution-tolerant




bottom organisms may also exist in the natural environment but




are generally found in small numbers.  The abundance of these




forms in streams heavily polluted with organics is due to their




physiological and morphological abilities to survive environ-




mental conditions more adverse than conditions tolerated by other

-------

-------
organisms.  Under conditions where inert silts or organic sludges




blanket the stream bottom, the natural home of bottom organisms




is destroyed, which also causes a reduction in the number of




kinds of organisms present.




     Streams grossly polluted with toxic wastes such as mine




drainage will support little, if any, aquatic life and will




reduce the population of both sensitive and pollution-tolerant




organisms.




     In addition to sensitive and pollution-tolerant forms, some




bottom organisms are termed intermediates, in that they are




capable of living in moderately polluted areas as well as in




clean-water situations.  These organisms occurring in limited




numbers, therefore, cannot serve as effective indicators of water




quality.




III. PROCEDURES




     In general, sampling stations were selected to correspond




with chemical and bacteriological stations used in previous




studies.  In the absence of such stations, location of sampling




points was based on known waste outfalls, accessability, and




stream bottom characteristics.  Each station was sampled once




and the kinds of macro bottom organisms were tentatively identi-




fied.  If possible, a qualitative and quantitative sample was




taken.  At some stations this was not feasible due to poor sampling




conditions, e.g., excessive depth, bedrock substrate, paucity




of bottom organisms, and in these cases only a qualitative sample




was taken.

-------

-------
     Quantitative bottom samples were taken using a Surber Square




Foot Sampler, an Ekman Dredge (0.5 sq. ft.) or a Petersen Dredge




(0.6 sq. ft.). Samples were screened on a No. 30 U. S. Standard




Series sieve and the animals retained were preserved in 10 percent




formalin solutions.




     Results of quantitative samples were expressed as numbers




of organisms per square foot of river bottom and qualitative




sampling in numbers of kinds of organisms per sample.
