I.  Purpose and Scope

     During the week of October 3, 1977, the Annapolis Field Office and
the Pennsylvania Department of Environmental Resources Reading jointly
conducted a one week intensive survey on the lower reach of the Lehigh
River between Palmerton and the mouth.  The study was  designed to define
low-flow water quality, hydrologic and benthic characteristics necessary
for calibration and verification of a mathematical model being developed
by the EPA Region III Water Planning Branch.  The water quality char-
acterization included analysis of stream and major discharge samples
for dissolved oxygen (DO), biochemical oxygen demand (BOD), nitrogen
series and other indicators of water quality conditions; a 24 consecutive
hour sampling program to define diurnal  fluctuations in DO; and a long
term laboratory experiment designed to differentiate between carbonaceous
and nitrogenous components of the long term BOD.   The  hydro!ogical
aspects of the study included stream gaging; flow measurement at major
discharges; and a dye study to determine travel  times  in various segments
of the river.  In situ sediment oxygen demand (SOD) measurements and
analysis of sediment samples for nutrients and selected metals were included
in the benthic characterization program.
    The study was planned for what was expected to be  a low stream flow
period so that water quality responses to pollutant loadings could be
evaluated under the most severe conditions.  The  optimal flow condition
for the study would have been about 600 CFS in the Lehigh River. Unfortunately,
-------
the study period was preceded by heavy rainfall  which increased flows to
over 2000 CFS.  The U.S. Army Corps.,  of Engineers participated in the
study effort by restricting releases  from the upstream reservoirs on
the Lehigh.  Through the release restrictions, the Corps was able to
decrease the river flow to about 1500 CFS by the end of the study period.
The study was initiated despite the high flows in hopes that the release
restrictions could drop the flow below 1000 CFS and because a good steady-
state low flow,, moderate temperature  condition would not occur for another
year.
     The U.S. Geological Survey also  cooperated in the study by measuring
cross-sectional areas and flows at selected places in the river.  The
results of their program are reported separately.

11.  Study Description

     The Annapolis Field Office and the Pennsylvania DER shared in both
the field and laboratory segments of the survey.  AFO field teams conducted
stream sampling from Allentown to Easton, effluent sampling at Bethlehem
Steel, time of travel, and benthic characterizations.  Pennsylvania DER
field personnel were responsible for effluent sampling at Allentown and
Bethlehem sewage treatment plants and the New Jersey Zinc Friedensville
Mine, stream sampling above Allentown, and stream flow measurement.
Teams from both DER and AFO participated in the diurnal study.  The
cyanide analyses were performed by the DER laboratory in Harrisburg and
all of the the other laboratory analyses were done at AFO.
-------
          A.  Stream Sampling
               On each of three consecutive days (10/4, 10/5, 10/6) stream
samples were collected at the stations shown in Table II-1.   For the stations
on the Lehigh River, spatial  composite samples (see III-A for explanation)
were collected and for tributary stations mid-channel  grab samples were
collected.  DO, pH and temperature were measured in the field and all  samples
were anlayzed for BOD5, TKN,  NH3, N02> NO-j, NBOD (nitrogenous BOD) and CBOD
(carbonaceous BOD).  One sample from each station was  analyzed for zinc,
cyanide, phenol and chlorophyll a_ sometime during the study.   (Analyses for
these parameters were staggered to avoid overloading the AFO  laboratory.)
               At the suggestion of Pennsylvania DER,  two sets of grab samples
were taken between Palmerton  and Allentown for zinc analysis.  This was done
to monitor the effect of the  discharges from New Jersey Zinc's Palmerton
plant.  Table II-2 lists the  locations for the zinc monitoring stations.

          B.  Effluent Sampling
               Starting on Monday October 3, 1977, three consecutive 24-hour
composite samples were taken  at each of the discharge points  listed in Table
II-3.  All of the composite samples were analyzed for pH, BODC,  TKN, NH , NO ,
                                                             5         3    2
NBOD and CBOD except those from New Jersey Zinc which  were only  analyzed for
zinc.  Grab samples were collected once each day at each station for pH,
temperature and DO.  With the exception of New Jersey Zinc,  all  of the
effluent samples collected during the first compositing period were analyzed
for cyanide and phenol.

          C.  Long Term BOD Experiment
               A laboratory experiment was conducted to measure  the carbonaceous

and nitrogenous components of long term (30 day) BOD.  While no standard
exists for measuring these parameters, a number of techniques have been
employed successfully.  AFO used two of these techniques during this
study.  The first technique was the more rigorous of the two and required
periodic measurement of DO and nitrogen fractions over the duration of
the experiment.  Total oxygen demand was measured using the change in no
while the nitrogenous component was derived using the changes in the states
of nitrogen.  The second technique involves the use of a nitrification
inhibitor and the measurement of total and carbonaceous oxygen demands
exerted over a 30 day period.  Detailed descriptions of both techniques are
included in Section IV.
          D.  Diurnal Study
               Begining at 8:00 a.m. on October 5, 1977, a 24-hour survey
was conducted to measure the diurnal DO fluctuations at the stations listed
in Table II-4.  Five (5) sets of samples were collected at each station
during the study.  Spatial composite samples were made for chlorophyll a_
analysis and the component samples were analyzed individually for DO,
temperature and pH.
          E.  Flow Measurement
               Stream flow measurements, with one exception, are from USGS
gaging stations located on the lehigh River and its tributaries.  The
exception, Saucon Creek, was manually gaged using a velocity meter and the
appropriate geometric data.  Stream flow measurements were made on October
4 and October 6.

               Flows at the two sewage plants are continuously monitored and
were available from the flow totalizers.   The New Jersey Zinc flow is an
estimate.  Bethlehem Steel  flows were measured by the company during the
week of the survey as a requirement under their NPDES discharge permit.

          F.  Time of Travel
               Travel times and average stream velocities were measured for
an 11 mile reach of the Lehigh River using a fluorometric dye tracing
technique.  Rhodamine B dye was released into the river at mile point 17.3
and the time of passage past 3 downstream points (river miles 12.55, 9.4,
6.0) was measured.

          G.  Benthic Characterization
               The sediment oxygen demand (SOD) was measured using an in
situ respirometer at Station L-13 (see Table II-l).  It had been planned
to measure SOD at Station L-16 also but due to the physical limitations of
the respirometer system it was not feasible.  A bottom grab sample was taken
at Station L-16 and analyzed for TKN, TP, TOC, zinc, chromium, cadmium,
copper, lead and iron.
III.  Field Procedures
     A.  Sample Collection
          1.  Stream Samples were all  surface grab samples taken in clean
plastic buckets.  At main river stations, separate samples were taken at
each of the three quarter points across the stream.  (These samples are
-------
designated as right, center and left quarter points looking upstream.)
Temperature, DC and pH were measured for each of the quarter point
samples and composite samples for laboratory analysis were made using
equal portions from each of the quarter point samples.  For the tributary
stations only one surface grab sample was collected at the point most
representative of the total stream flow.  Temperature, DO and pH were
measured for the sample and a portion was preserved for laboratory
analysis.
               2.  Effluent.Samples were either grab samples or 24 hour
time proportioned composite samples taken as close as possible to the
point of discharge to the receiving stream.  Grab samples, one each day
at each station, were taken in plastic buckets for temperature and DO
analysis.  Temperature was measured in the bucket and samples for DO
analysis were poured into standard 300 ml DO bottles through a funnel
to avoid excessive aeration.  Composite samples were collected using  ISCO
(both models 1392 and 1580) automatic samplers.  Composite sample aliquots
were collected at half hour intervals at all stations except New Jersey
Zinc which was sampled at 20 minute intervals.  Sample temperatures were
maintained at about 6°C using ice in the samplers ,
               3.  Sediment Samples were grab samples collected using a
model 426/SM Mud Snapper made by GM Manufacturing and Instrument Corporation.
After collection, the samples were stored unpreserved in  plastic cups.
               4.  Containers.  Samples for  nutrient/BOD  analyses were stored
unpreserved  in new gallon plastic cubitainers.  Phenol samples were stored
                                       10
-------
in acid washed glass containers.  Zinc and chlorophyll  a_ samples were each
stored in separate new quart cubitainers.  Cyanide samples were stored in
clean glass bottles.

     B.  Sample Preservation
          All samples except those for dissolved oxygen analysis were kept
at 4°C until they were analyzed.

          1.  Phenol samples were preserved by adjusting the sample pH to
less than 4 with phosphoric acid and adding copper sulfate.
          2.  Cyanide samples were preserved by adjusting the sample pH to   *
more than 12 with sodium hydroxide.

          3.  Zinc samples were preserved by adjusting the sample pH to less
than 2 with nitric acid.

          4.  Dissolved Oxygen (DO) samples were preserved with 2 ml manganous
sulfate solution, 2 ml potassium hydroxide-potassium iodide solution and 2 ml
of concentrated sulfuric acid.  The samples were stored in the dark until
the analyses were performed.
     C.  Field Analyses

          1.  Temperature was measured using a  YSI dissolved oxygen meter
for samples on which DO analysis was done in the field.  Other temperature
measurements were made with a calibrated thermometer.
                                        11
-------
          2.  Dissolved Oxygen (mg/1 DO) in the stream samples was
determined with a YSI DO Probe 15739 and YSI Meter Model 57.  The meters
and probes were air calibrated and measurements were made while manually
stirring.
Ref:  EPA Methods for Chemical Analysis of Water and Wastes, 1974, p. 56.

          3.  p_H_ was measured using Leeds and Northrop Model 7417 pH meters
with Ingold number 2761 7-02 pH electrodes.  Meters were calibrated using
buffer solutions with pH 4, 7 and 10.  Measurements were recorded after the
meter reached equilibrium in the sample.

     D.  Flow Measurement

          1.  Stream Flows were read from USGS gage stations with the
exception of Saucon Creek which was manually gaged using a cup type velocity
meter.
          2.  Waste Discharge Flows for the Allentown and Bethlehem sewage
treatment plants were read from the totalizers on the continuous  recording
flow meters at the plants.  Flows from Bethlehem Steel were measured by the
company as  required by their NPDE5  discharge permit.  The company did only
one measurement at each outfall and the methods of measurement included use
of V-notch  weirs and lithium dilution techniques.  Flows for New  Jersey
Zinc are company estimates.

     E.  Time O'f Travel

          Travel time in the  river  was measured using a fluorometric dye
technique.  One quart of Rhodamine  B dye was released into  the river at
                                        12
-------
the Hamilton Street Bridge, Allentown (river mile 17.3) at 3:00 a.m.  on
October 5, 1977.  The time of passage for the dye mass was subsequently measured
at three downstream points.  The dye cloud was tracked using a continuous flow
through fluorometer system consisting of a submersible pump, a Turner Model
111 Fluorometer with a flow through door and Corning orange (3-66) and
blue (4-97) filter, and a Rustrak strip chart recorder.  The submersible
pump was placed in the river and sample was continuously pumped through
the fluorometer flow-through door.   The recorder provided a continuous graph
of dye concentration in the river and the elapsed time between stations was
taken when the maximum dye concentration (peak) was recorded.   Average
velocity for each reach of stream was calculated using the distance between  two
stations and elapsed time for the dye peak to travel between the two  stations.
     F.  Sediment Oxygen Demand

          Sediment oxygen demand (SOD) was measured at Station L-13 using
a benthic respirometer.  (See Appendix C for explanation and
description of respirometer.)  The respirometer was lowered from a boat into
soft sediment where it could make a watertight seal.  The DO of the water
trapped beneath the respirometer was measured initially and the changing DO
level was monitored over an 80 minute period.  A DO bottle filled with
bottom water was attached to the respirometer and the initial  and final
DO was measured to isolate the demand exerted by the water.

     C.  Phenol (rag/1  Phenol):  was determined colorimetrically via the



4-amino-anti-pyrine method.  The samples were distilled to remove potential



interferences.



Ref:  EPA Methods for Chemical Analysis of Water and Wastes, 1974, p.  241.





     D-  Cyanide (mg/1  CN):  was measured using a Technicon Auto Analyzer



colorimetric procedure  with UV light and pyridine-barbituric acid as the color



reference.

     E.  Metal s (mg/1  Total):  Total In; Mn; Fe; Pb; Cd ;• Cu; and Cr were



quantitatively determined by atomic absorption spectrophotometry using a



Varian AA-6 A.A. Spectrophotometer.  Water samples were treated with nitric



acid and refluxed on a  hot plate until digestion was complete.



Ref:  EPA Method for Chemical Analysis of Water and Wastes, 1974, p. 78.





     F.  Sediments



           1.  Total Residue (% Dry Weight):  The % dry weight  was determined



by placing = 5  ml of sample in a crucible which had been previously heated



for 24 hours at 103 - 105  C for 24 hours and cooled in a dessicator before



weighing.  The "wet" weight was then determined and the sample  plus crucible



returned to the 103 - 105 °C oven for 24 hours.  The final "dry" weight of



the sample after drying is then determined and the % dry weight calculated.



           2.  Total Organic Carbon (% Dry Weight - TOC):  Predried samples



(at 35°C for 24 hours)  were analyzed by the Oceanography International Total



Carbon System.   The sample, potassium persulfate and phosphoric acid were



sealed in glass ampules and autoclaved at 230^C for four hours.  Organic



materials contained in  the sediment samples were converted to carbon dioxide
                                   15
-------
by this wet chemical oxidation step.

      Instruction and Procedure Manual for Oceanography International
           3-  Total Kjeldahl  Nitrogen (% Dry Weight - TKN-N):   The procedure
for sediment samples was the same as  that employed for water samples but
digestion of 0.05 gms of sediment (wet weight) was carried out using
potassium sulfate and sulfuric acid.   The mixture was refluxed over a
flame until the organic nitrogen was  converted to ammonium.  The answer was
corrected to % dry weight using the dry weight determination described
previously.
Ref:  EPA Methods for Chemical Analysis of Water and Wastes, 1974, p. 182.
           4.  Total Phosphorus (% dry weight - TP04):  Total Phosphorus in
sediment samples was determined by manually digesting  (in an autoclave for
30 minutes at 15 psi)   the sample with ammonium persulfate and sulfuric
acid to convert the various forms of phosphorus to orthophosphate.   The
orthophosphate  was measured on a Technicon Auto Analyzer. In this colorimetric
method ammonium molybdate reacts with the orthophosphate in the acid medium
to form a heteropoly acid, molybdophosphoric acid.  This acid is reduced
by ascorbic acid to form the intensely colored complex, molybdenum blue.
The amount of color produced is directly proportional  to the amount of
phosphorus present.
Ref:  EPA Methods of Chemical Analysis of Water and Wastes, 1974, p. 256.
                                       16
-------
           5.  Metals (mg/kg dry weight):  Sediments were anlayzed for Cr;
Cd; Cu; Pb; Pe; and Zn via atomic absorption spectrometry using a
Varian AA-6 Spectrophotometer.  The sample preparation and digestion
were as follows:
               1.  Sample dried at 35°C (minimum of 24 hours).
               2.  Removed from incubator/oven and ground to "natural"
particle size  (large rocks, shell, leaves, etc. removed).
               3.  Sample dried additional 24 hours.
               4.  Sample weighed; 3-5 grams for silts and clays, 15 grams
for sands (i.e., ocean sediments).
               5.  Transfer to glass-stoppered Erlenmeyer.
               6.  Add equal volumes deionized-distilled water and
concentrated HNOs (^ 20 - 25 ea. = RN).
               7.  Heat in shaking water bath at 58°C for 4-6 hours.
               8.  Filter with .45 micron membrane filter, dilute to 100 ml
               9.  Sample is now ready for analysis.
          G.   DO/BOD
               1.  Dissolved Oxygen fmg/1  D.0.):in the effluent samples was
determined by the azide modification of the basic Winkler Method, with the
titration done potentiometrically with a Fisher Automatic Titralyzer.
Ref:  EPA Methods for Chemical Analysis of Water and Wastes,  1974, p.  51.
                                       17
-------
               2.  Biochemical Oxygen Demand  (mg/1 BOD,-} : The samples were
                   " I ™  ' •"	 ~ '  "   " "-•—" • -"  ,1111 IB-IP          ^J
incubated at 20°C for five days in the dark.  The reduction in dissolved
oxygen  (as measured by YSI #5750 BOD probe) concentration during the
incubation period yielded a measure of the biochemical oxygen demand.
                    River water samples were  analyzed for BOD unaltered,
incorporating indigenous biota and nutrients.
                    The following Bethlehem Steel samples were altered by the
addition of 1 ml  of stale settled sewage (seed) per 300 ml  of sample:  outfall
005;  00$ 007;  008;  010; and 012.   The seed was obtained from the Maryland
Department of Natural Resources.
                    The addition"of seed was to assure the presence of an
adequate bacterial population.   This alteration necessitated that a blank
(distilled water plus 1 ml of "seed") be carried through this experiment
to compensate for potential BOD contamination.
                    The following STP and industrial effluent samples were
altered by the addition of "seed" (1 ml/bottle) and by dilution with APHA
dilution water:  Allentown STP; Bethlehem Steel outfall 015 and 031; and Bethlehen
City Municipal STP.  Allentown STP samples were found to have significant
residual chlorine content and ^ 1.0 mg/1 of sodium sulfite solution  (0.025N
 Na2SQ3) was added to eliminate this potential interference.  These alterations
necessitated that a blank (300 ml APHA dilution water  plus 1 ml of  "seed")
be carried through this experiment to compensate for potential BOD contamination.
A dilution factor is also included in these calculations.
Ref.:   EPA Msthcds for Chemical Analyses of Water and Wastes, 1974, p. 11.
-------
          H.  Long Term BOD
               A set of laboratory experiments was conducted to characterize
long term oxygen demand and to differentiate between the nitrogenous and
carbonaceous components of long term BOD. The long term oxygen demand was
estimated by extending the standard BOD test incubation period from 5 days
to 30 days.  The nitrogenous component of total BOD was estimated by
measuring the changes in the states of nitrogen during the course of the
BOD incubation and also independently by a method of differences in which
a nitrification inhibitor was used.
               For determination of the BOD, , samples were set up as
described previously with the exception that 6 replicate sample bottles
were used as part of the nitrification experiment.  The dissolved oxygen was
measured for each sample after 0; 6; 12; 20; and either 29 or 31 days of
incubation to determine the long term BOD.
               One of the six replicates mentioned in the previous paragraph was
sacrificed after 0; 6; 12; and either 29 or 31 days of incubation to measure
Total Kjeldhal Nitrogen (TKN); ammonia (NH3); nitrite (N02); and nitrate (N03).
The changes in concentration in the states of nitrogen were used to calculate
the nitrogenous oxygen demand by the equation:
               NOD (mg/1) = 3.43  (AN02-N + ANOs-N) + 1.14  (AN03-N)
               where A = final concentration - initial concentration.
               An inhibitor  2-chloro-6(trichloromethyl) pyridine (TCMP) was
also employed as part of the long term study.  Two bottles of the six
replicates were spiked with TCMP and the dissolved oxygen measured.  The
                                        19
-------
inhibitor was added to stop nitrification while allowing all  other heterotrophic
respiration to proceed.  The inhibited bottles expressed only carbonaceous
demand whereas the uninhibited bottles expressed the total  BOD demand (NOD  +
CBOD).  By difference the nitrogenous  oxygen demand was calculated.
               The first-order deoxygenation constants k]o(day  )  of the NOD^
and CBOD as measured by the inhibitor  were determined by a  graphical  method.
This method relies upon the observation that the relation (1-10 "k't)  of the
classical BOD equation y = L0 (1-10    )  is very similar to the expression
2.3 k-jQt  [l + (2.3/6)k]Qt]   , where k]Q is the deoxygenation constant (day"')
and L0 is the initial remaining oxygen demand at time t = 0.
               Together the two equations reduce to:
y = L0 2.3 kt [l+(2.3/6)kt] '3  or  (t/y)1/3 = (1/2.3 L0k)  +  (2.3k)2/3t/(SL0)1/35
such that a plot of (t/y)'/3 vs t yields  a linear relation  with slope
m = (2.3k)2/3/(6L0)1/3 an(j intercept b =  l/(2.3k L0)1/3.  The BOD k10 and L0
values can therefore be determined as  follows:  k = 2.61 m/b and L0 - 1/(2.3 b^k).
The correlation coefficient for this linear approximation was taken as an
indication of the "goodness-of-fit" to the first order kinetics.
               Limitations of Long Term Laboratory BOD Experiments
               1,.  It should be emphasized that this was not a standard
method and that the data reflects not only the imprecision  of the
analytical methods (Appendix B) for determining the states  of nitrogen
but also the variability associated with biological processes.  The
interpretation oir the results should include a consideration of this
variability.
                                         20

               2.  Nitrification is an extremely fragile biological  process
and is affected greatly by environmental  conditions.   The problems  with
using laboratory experiments to study field conditions (in situ)  are
therefore potentially significant.
               3.  Nitrification is a surface phenomenon with  much  of
nitrification in clear shallow rivers occuring on the surfaces of mud
(aerobic), plants, slime, etc.   Laboratory experiments  involving the
incubations of clear-shallow stream samples may not reflect the extent
of in situ nitrification.  The Lehigh River remained  quite turbid during
this study and significant nitrification  activity was expected in the
water column.

          G.  Benthic Characterization-Sediment Oxygen Demand

               At station L-13 the bottom was  hard and sandy In  the middle

and on the right side (looking upstream).  Near the shore on the right

side the bottom was a black, granular material, possibly coal  dust, and

the respirometer was able to seat properly.  The D.O.  inside the respirometer

dropped 2.0 mg/1 in 80 minutes during the test.  There was no  change in

the accompanying dark bottle D.O., therefore it is assumed that  all  of the

D.O. change is related to benthic demand.  Following are the calculations

for SOD at L-13.

           S'  = 2.0 mg/1  •=• 80 minutes = .025 mg/l/min

           S"  = 0

           S = .025 mg/l/min

           SOD = 107 x S

           SOD       = 107 x .025 mg/l/min = 2.675 g/m2/day
              14.5°C
                                 (20 - T)
           SOD     = SOD      x 6
              20°C      14.5
                                  (20 - 14.5)
                   = 2.675 x 1.06             = 2.675  x 1 .414 =  3.78 g/mz/day
                                        39

VI.   Conclusions

     A.  A review of the long-term BOD data revealed a general  trend
of decreasing TKN-N concentration correlated with increasing (N02+N03)-N
concentration, associated with the processes of nitrification.   The
one  exception to this pattern was Bethlehem Steel outfall  031.   This
outfall had ei high average BOD 29/31  of 763 ppm and a high average
initial TKN-N of 359 ppm.  However, little or no (N02+NOs)-N was formed
after 30 days of incubation.  The sample was analyzed for  phenol &
cyanide and found to contain 35.9 ppm total phenol  and 50  ppm cyanide.
This suggested that the outfall  was toxic to nitrifying bacteria but
not  to the hsterotrophic species present.

     B.  Nitrite was formed with incubation, but except for 771006-15
and  16 it decreased to "not detectable" (NO) after 30 days of incubation.

     C.  A paired t-test of the results of the calculated  NOD and
TCMP NOD over the combined 218 paired data sets established at the
95% confidence level (t = 0.75) that there was no significant difference
in the results of the two NOD methods.
     D.  The; average river CBOD and NOD rate constants ke  were
respectively 0.090  (n = 41) and 0.094 (n = 38).

     E.  The carbonaceous demand followed first order kinetics  in
the river samples.  The river NOD involved at least a six  day lag
phase, in which the nitrifying bacteria present may have become
acclimated to the experimental conditions and/or increased in number
enough to make a significant contribution.  The river NOD rate

calculations are included in Table V-C-4.   The  deoxygenation  constants
and ultimate NOD were calculated  using "all  points"  and  recalculated
excluding the early lag phase.   This  lag  phase  was  assumed  to be  a
laboratory artifact and the deoxygenation  constants  compiled  (Table
V-C-8) were based on the last three data  sets.

     F.  The effluent samples which were  both seeded and  diluted  often
depleted oxygen (CBOD) in a linear pattern with time, which resulted
in poor correlation coefficients  to first-order kinetics.   The  NOD
for these samples displayed a lag time similar  to  the river samples
(Table V-C-5 and V-C-6) and the ke values  reported  were  similarly
based on the last three data sets.

     A problem with the TKN analysis was encountered with several samples.
These results were considered questionable and appear as L.A. (laboratory
accident) in the data summary table.  The results for these samples were
as follows:

     It  is unclear whether the problem was due to interferences present
in the sample or due to the imprecision in the TKN-N test amplified by
the dilutions involved.

                             APPENDIX C
                        Benthic Respirometer

     The AFO benthic respirometer is shaped like a pyramid with vertical
and horizontal  stabilizing flanges.   A DO probe is fixed in one side wall
of the pyramid and a small pump is attached on the wall with the pump
discharge opposite the DO probe membrane.  Circulation from the pump
discharge provides the mixing required when using the probe method of
DO measurement.  The inside volume was measured to be 27.62 1 and it
                             o
covers a surface area of 4 ft .  (See  Figure III-l).  Plotting the DO
concentration inside the respirometer against time typically results in
a constant negative slope for the first 30 to 60 minutes; after this
initial period, the slope gradually approaches zero (see  Figure III-2).
The initial slope, S1 (mg/l/min), is taken as the net respiration in the sediments
and trapped water.  If a dark bottle filled with bottom water is placed next
to the respirometer during operation, the DO concentration will decline
due to aerobic respiration in the trapped water.  Subtracting the average
respiration rate in the water column, S" (mg/l/min), from the initial slope
measured by the respirometer will give the respiration in the sediments:

          S Ung/1/min) = 5' - S11                                             (1)

     This measure of benthic respiration must be converted to standard  units
as follows:
                      2
          SOD   (g DO/m /day) = S  (mg/l/min) x  1440  (min/day)  x 0.001  (g/mg)
            I 10.764  (ft2/m2) x V  (1) x A"1 (ft2)   «=  0.258 x S  x  V/A        (2)

Given the volume and bottom surface area of our particular benthic
respirometer, equation (2) becomes:

          SODT (g D0/m2/day) = 107 x S (mg/l/min)                         (3)

Aerobic bacterial respiration is generally considered to be an exponential
function of temperature such as:

     Biochemical  oxygen demand (BOD) is A bioassay procedure concerned

with the utilization of oxygen in the biochemical  oxidation (respiration)

of organic material.  This test is one of the most widely used measures

of organic pollution and is applied both to surface and waste waters.

The standard method  of BOD measurements adopted by APHA1 is a five

day test in which a  water sample is maintained at  20°C in the dark

and oxygen depletion is monitored.  The five day incubation period

was selected to maximize the oxygen demand associated with the

oxidation of carbon  compounds while minimizing the oxygen demand of

autotrophic organisms.  That portion of the BOD due to the respiration

of organic matter by heterotrophic organisms is termed the carbonaceous

oxygen demand and that portion involved with nitrification is termed

nitrogenous oxygen demand.  The desire to separate the NOD and CBOD

results not only from the fact that the organisms  responsible for these

components have different nutrient requirements, but also because

they differ in reaction rates, A02/Atime; temperature coefficients;

and tolerance to toxic materials.  Nitrifying bacteria are in general

slower growing2;  more drastically affected by temperature3; and are more

-------
sensitive to materials as**:  phenols; cresol ;  halogenated solvents;
heavy metals; and cyanide.  The organisms involved in the CBOD and
NOD processes would therefore be expected to  react differently to the
same aquatic environment.  The determination  of the BOD components
would better define the BOD test results and  aid in extrapolating these
results to the prediction of dissolved oxygen profiles in a body of water.
     The purpose of this paper is to demonstrate that a simple
procedure involving an inhibitor to nitrification, N-serve, could
provide an accurate and precise measurement of nitrification occurring
in the  BOD   test while not affecting the carbonaceous oxygen demand.
                              Nitrification
    Nitrification is the conversion of ammonia to nitrate by
biological respiration.  This type of respiration is employed by
seven genera of autotrophic nitrifyers.5
    It should be noted that heterotrophic nitrification can also
produce NO;? and N0§ by reactions that do not involve oxidation.6
However, only Nitrosomonas spp and Nitrobacter spp are regularly
reported by in situ nitrification studies.2  Therefore, the treatment
of nitrifying river samples with inhibitors specific to Nitrosomonas
and Mitrobacter can be expected to stop all appreciable nitrification.7
    The reactions involved in nitrification are as follows:
    NH4+  +  -%02  Nitrosomonas  2H+  +  ^-^  Equation T
    N02-  +   h 02  rh'trobacter-y  N03-              Equation 2
The stoichiometries of the nitrification reactions dictate that the
conversion of T gram of nitrogen from ammonium to nitrite utilizes
-------
3.43 grams of oxygen and the conversion of 1  gram of nitrite-nitrogen
to nitrate-nitrogen involves the utilization  of 1.14 grams of oxygen.
However, nitrifying bacteria are autotroph-'c  and as such utilize
a portion of the energy derived from nitrogen oxidation to reduce C02»
their primary source of carbon.  The net result is a reduction in
the amount of oxygen actually consumed.  Short term, zero to five
day, laboratory experiments8'1''10 employing cultures of Nitrosomonas
and Mitrobacter have related the depletion of oxygen to the production
of nitrite and nitrate with the corresponding oxygen to nitrogen ratios
of 3.22 and 1.11.  However, in long term experiments, the decay of
these organisms would be expected to exert an oxygen demand approximately
equivalent to the oxygen originally generated, resulting in an
overall relation not significantly different  from 4.57.11
     The equation used to calculate the NOD from the changes in
nitrogen states upon incubation was:
        NOD = 3.43 (AN02-N + AN03-N) + 1.14 (ANOs-N)     Equation 3
        where A = final - initial .
The potential NOD was calculated as:
        potential NOD = 4.57 (TKN)                       Equation 4
        where TKN = (NH3-N + Norg-N)and N02-N was insignificant.
     The NOD was also measured by the difference in oxygen depletion
in an unaltered sample and in a sample altered by the addition of
the nitrification inhibitor, nitraoyrin.
                         Nitrification Inhibitor
     The inhibitor used was formula 2533 Nitrification Inhibitor,
a product of the Hach Chemical Company.  The  product consists of
-------
2-chloro-6-(trichloromethyl)  pyridine known as TCMP or nltrapyrin.



This compound is plated onto  a simple inorganic salt which serves as



a carrier and is soluble in water.   The DOW Chemical Company, Midland,



Michigan, markets this chemical  under the name N-Serve as a fertilizer



additive.



     Studies12'13'11*'15 using nitrapyrin suggest that it acts as a



"biostat" at moderate concentrations to delay nitrification and



aids in the retention of ammonia or urea fertilizers on crops by



retarding conversion to the more highly leachable N03~.  TCMP is



slowly biodegraded to 6-chloropicolinic acid which leaves the fields



in their original state, with no further inhibition to nitrification.



The advantage of this is that 20 to 30 day NOD assays may be performed



without significant inhibitor contribution to the carbonaceous



demand.11'16



     Because of concern for  the potential environmental impact



resulting from extensive farm use, studies were performed on the



toxicity of this material.  These studies have revealed the inhibitor



to be very selective and effective at stopping nitrification when



used at a concentration of 10 mg TCMP/1 ^M6,17

                             Experimental





A.  NOD Synthetic Ammonia Experiment



    1.   300 ml  BOD bottles were weighed before and after the addition



        of water and found to be reliable  to within 1%.   They were



        used as volumetric flasks for all  experiments.



    2.   Two ml  of a solution of O.lSOg glucose/1  plus  Q.150g glutamic



        acid/1  were spiked into BOD  bottles  using a repipet.



    3.   Stale settled sewage was filtered  through Kimwipes18 and



        diluted.  One ml  was dispensed into  each  BOD bottle.



    4.   NH3-N spikes were made using a 44.5  mg NH^l-N/l  stock solution,



    5.   The BOD bottles were then filled with APHA standard  dilution



        water.1



    6.   Ammonia was assayed using a  Technicon automated  colorimetric



        phenate method.19  Nitrate was determined using  a Technicon



        automated cadmium reduction  method and nitrite was assayed



        using a Technicon automated  NEDA-diazotizing method.19



    7.   Dissolved oxygen (DO) was monitored  using a YSI  Model  #57



        meter and #5720 probe.  DO measurements were made before



        and after incubation which was carried out in  the dark at  20°C.



    8.   The nitrification inhibitor  (Hach  Chemical  Co. #2533)  was



        dispensed, using a powder dispenser, directly  into the BOD



        bottles.  This allowed quick and uniform  additions of the



        inhibitor.  Two sets of bottles were filled with each sample;



        one received the inhibitor and represented CBOD  and  the



        uninhibited bottle expressed total BOD.  The NOD was determined



        by difference.
-------
B.  NQD Syntletic Nitrite Experiment



        This experiment was identical  to the synthetic  ammonia



        experiment except spikes  of NaN02 were  substituted for  NH4C1 .



C.  Synthetic Glucose Samples-Respiration Experiment



    1.  BOD bottles were spiked with approximately 3.0  ml  of a  3.0g/l



        stock glucose solution using a repipet.   Raw sewage influent



        was filtered through Kimwipes and diluted with  distilled



        water.  One ml  of this seed was spiked  into each bottle.  TCMP



        was added to one-half of the bottles using the  Hach powder



        dispenser and all bottles were filled with standard BOD



        dilution water.1



    2.  Oxygen was bubbled through the bottles  using a  Fisher gas



        dispersion tube and purified oxygen.  The samples  were  then



        incubated in the dark at 20°C.



    3.  Initially and after different periods of incubation, samples



        were placed in a refrigerator at 4°C to stop bacterial  activity.



        At the conclusion of the experiment bottles were assayed for



        glucose.20  The samples were first filtered through a 0.45y



        Millipore filter to remove bacteria.  Four ml of each filtrate



        were placed into 125 ml Erlenmyer flasks; which had been



        chromic acid washed and muffle furnaced for 24 hrs. at 550°C.



        Repipets were then used to dispense 4 ml of phenol solution



        (25.0 gms/500 ml deionized water) and 20 ml of acid reagent



        (2.5 g hydrazine sulfate/500 ml cone. f^SO^.  The acid



        reagent was added with swirling and the flasks were placed in



        a refrigerator at 4°C for 2 hours to cool.  The absorbance
-------
        was read on a Varian  635  spectroohotometer  using  5  cm  quartz



        cells at 490 my.   A 500 mg/1  glucose  stock  solution  was



        prepared and appropriate  volumes  were diluted with  deionized



        water to generate standard  curve  solutions.  The  resultant



        standards were filtered and assayed as samples.

                                 correlation coefficient =  0.999



    4.   Dissolved oxygen  was measured directly in the BOD bottles



        using the YSI 5720 probe  and  the  pH was determined using a



        Corning 110 research meter  and electrode.



D.   TCMP and the Measurement of Dissolved Oxygen



    1.   Electrode and Winkler  Methods



        a.   A 20 liter carboy  of  deionized water  was stirred with



            a magnetic stirring bar as water  was  slowly siphoned into



            16 sets of four 300 ml  BOD bottles and capped.   This
-------
        procedure was repeated to generate 32 sets of 4 bottles.



    b.  TCMP was added to two bottles from each set using the



        Hach powder dispenser.



    c.  Two bottles (one with TCMP) were analyzed for DO via



        the Winkler azide modified method1 using a Fisher Model  41



        jDotentiometric titralyzer.  An incubation period of 2 to 3



        hours after the addition of the inhibitor and Winkler



        reagents was allowed prior to titration to enable potential



        reactions, which may have resulted in interferences, to  occur.



    d.  "he remaining two bottles of each set (one with TCMP) were



        analyzed by a YSI 5720 DO probe and #57 meter.  This



        meter had been previously calibrated against the Winkler



        method as outlined in Standard Methods.1



2.  Starch End Point - Azide Modified Winkler DO



    a.  Fourteen potassium biiodate standards, each with 3 ml



        of Fisher SO-P-340 stock biiodate solution (0.0250 N),



        were prepared as outlined in APHA Standard Methods1



        for Winkler Dissolved Oxygen measurements.



    b.  To seven of these TCMP and starch (Fisher T-138 thyodene)



        were added.



    c.  The samples were titrated with sodium thiosulfate solution



        using a Fisher Model 41 titralyzer in the manual mode



        and titrating to the disappearance of the blue color.



Potomac River Study



1.  The BOD test employed was that outlined in Standard Methods



    APHA 14th edition.1  The river water samples were stored at
-------
        4°C until  analysis.   Three-hundred  ml  of each  sample  was



        placed in  each of two BOD bottles.   The  bottles  were  purged



        for 15 seconds using  purified  oxygen and a  Fisher  gas  dispersion



        tube to obtain an initial  DO of 10  to  15 rng/1.   One bottle of



        each pair  was dosed with  the Hach Co.  #2533 Nitrification



        Inhibitor.



    2.   Dissolved  oxygen  was  measured  immediately using  a  YSI  5720 DO



        probe and  again after 20  days  of incubation in the dark at 20°C.



    3.   TKN was analyzed  on the unaltered river  samples  using  a



        Technicon  automated phenate method.19



F.   Lehigh  River Study



    1.   Samples were  prepared in  six replicate BOD  bottles and two



        bottles of each set were  spiked with TCMP using  the Hach



        powder dispenser.



    2.   Dissolved  oxygen  was  analyzed  immediately and  after several



        periods of incubation in  the dark at 20°C using  a  YSI  5720



        DO  probe.



    3.   One bottle was sacrificed  after each DO  reading  and assayed



        for NO£-N  and NO§-N by the automated methods previously described.



    4.   Three classes of  sample preparation  were employed  to allow



        for differences in sample  character:



        a.   River  samples were unaltered.



        b.   Industrial  effluents  with  low level  NH3-N were seeded with



            1  ml of stale settled  sewage per 300 ml  BOD  bottle and



            correction blanks were carried  through  the experiment.
-------
        c.   Sewage  treatment  plant  effluent  samples  and  industrial
            effluents  with  high  levels  of ammonia  were diluted.
            Samples of October  4 were diluted  by  a factor  of  30  and
            those of October  5  and  6 were diluted  by a factor of 15
            with seeded APHA  diluted water.   Correction  blanks
            were carried through the experiment.
                         Results and Discussion
NOD Synthetic Ammonia  Experiments
     Initial experiments were performed on synthetic samples  to
establish the accuracy of the  NOn   determinations  made using TCMP.
The experiment consisted of spiking samples  of APHA dilution  water1
with a glucose-glutamic acid  solution, bacteria,  and ammonia.  The
concentrations of ammonia,  nitrate, and nitrite were then determined
before and after incubation.   The changes (A)  in  the states of nitrogen
were determined and used to calculate the actual  NOD wich had occurred
(Equation #3).
     The dissolved oxygen initially and finally present  was determined
in all bottles.  The oxygen utilized in the inhibited bottles was
taken as CBOD where as the depletion in the uninhibited  bottles was
taken as NOD plus  CBOD.  This NOD, signified as NOD-TCMP, was
determined  by the  average difference observed between these sets.
     The results of these experiments are presented in Table  1.  A
paired student's t-test of the nitrogenous oxygen demand established
(t=1.41, n=32)  at  a=.05 that there was no significant difference between
these two methods  of  NOD determination.   The average difference
between  the two methods was  0.3  mg/1 NOD.

     The oxygen depletion was  monitored over time for several  of the
samples and the DO data is presented in Figure  1.  This  work
illustrates the potential use  of the inhibitor  in establishing
deoxygenation constants for NOD separate from CBOD.
     The seed source for these experiments was  stale sewage.   The
sporadic growth of the nitrifyers observed during these  experiments
was largely corrected in later work by filtration and the use  of
more seed material.
NOD Synthetic Nitrite Experiment
     The effect of TCMP upon the growth of nitrifying bacteria
was tested using spikes of sodium nitrite into  seeded APHA dilution  water
containing glucose/glutamic acid (Table 2).   The  calculated nitrogenous
oxygen demand based on the measured changes in  the states of  nitrogen
was significantly higher than  that predicted by the use  of TCMP
when compared by a paired t test (t=7.3 at a=d.05 & n=15). The changes  in
nitrite and nitrate were also  measured in the TCMP spiked bottles,
which allowed the calculation  of the NOD occurring despite the presence
of TCMP.  This calculated error matched favorably (correlation
coefficient = .92) with the average error actually observed between  the
calculated NOD in the samples  and that measured using TCMP.  The
inhibitor  had little  inhibitory  effect upon Mitrobacter spp.
since all of the NO^-N in the spike was converted to NO§-N after
30 days of incubation.
     Although the mechanism of its action is unclear, the inhibitory
effect of nitrapyrin is apparently restricted to Nitrosomonas.  This
selectivity is advantageous in that it stops the process of nitrification
at ammonia with little or no effect on urea hydrolysis21, thus assuring
an adequate nitrogen source for the heterotrophic bacteria contributing

to the CBOD.  The disadvantage of this selectivity is that Nitrobacter



are not inhibited and N02 will be oxidized to N0§.  This limitation



generally represents a small  error since the concentration of nitrite-



nitrogen is generally much smaller than Total Kjeldahl  Nitrogen in



river water.  Further, the demand associated with the N02-N initially



present is 1.14/4.57 or one-quarter that associated with the TKN-N



initially in the sample.



Synthetic Glucose Samples-Respiration Experiment



     To directly determine the effect of TCMP on the rate of heterotrophic



respiration, synthetic samples of APHA dilution water were spiked  with



glucose and seed bacteria.  Several  bottles were immediately assayed



for glucose, dissolved oxygen, and pH, while others were incubated



and later analyzed for these  parameters.  The results,  compiled in



Table 3, indicate that TCMP did not appreciably decrease the rate  at



which glucose was utilized.  The potential  problem with this



interpretation is that these  results may have been at steady state



and therefore may not actually represent the rate at which steady



state was achieved.



     This experiment was again performed with the emphasis placed  on



determining when steady state occurred in bottles in which growth



was observed.  Glucose concentration, pH, and dissolved oxygen level



were measured initially and periodically during incubation.  The



final levels determined were  similar to those in the previous



experiments.  The results, compiled in Table 4 and Figure 2, indicate



that:  the glucose respiration rate was not significantly affected



by TCMP; steady state was not established after 4 days  of incubation;



and suggested that the interpretation of the first experiment was  valid.

     Assays on TCMP treated samples consistently gave lower glucose



values than the control samples.  Bottles which were assayed



immediately after preparation demonstrated this same pattern  and this



suggested that a chemical  rather than a biological  mechanism was involved,



     It has been suggested that glucose is toxic to the growth of



nitrifying bacteria.22  It has also been suggested  that the lack of



nitrate and nitrite formation when glucose was added to actively



nitrifying samples indicated a preference for glucose respiration by



nitrifying bacteria.23  The contribution of nitrifying bacteria to the



overall glucose utilization measured in this study  was probably



insignificant since the nitrifyer population present in stale settled



sewage collected during freezing weather is relatively sparce and



an incubation time of 4 days or less is not sufficient for significant



nitrifyer growth from this seed.  Further, the acidic pH conditions



which occurred during this experiment were not ideal for nitrifyer growth,



TCMP and The Measurement of Dissolved Oxygen



     The effect of TCMP on dissolved oxygen measurements made using



the azide modified Winkler potentiometric method and the polarographic



electrode method was determined using inhibited and uninhibited



deionized water samples.  A paired t-test for the Winkler assayed



bottles (t=1.24, n=31) revealed no significant affect on the Winkler DO



method at a 95% confidence level.  The average difference between TCMP



treated and untreated bottles was 0.1 mg/1 D.O.  Similar results were



obtained for the electrode method with a paired-t test result of 1.48



with n=32 and a=.05.
-------
     Fourteen identical  biiodate standards  were  also  analyzed  using



the starch end point in  the Winkler determination.  The  average



difference in the titrant required  for  inhibited and  uninhibited  bottles



was 0.03 ml ,  which indicated that TCMP  did  not affect the  starch  end



point determination.



Potomac River Study



     With the completion of the preliminary experimentation  using



synthetic samples, the use of TCMP  in the determination  of nitrogenous



oxygen demand was tested using environmental  samples. Potomac River



samples were  assayed for NOD during the summer of 1977.  Nitrogen analyses



were limited  to TKN.  The river historically3 had a pattern  of rapid



biological activity and  long term incubation was expected  to yield



essentially complete nitrification.  The potential  NOD was calculated



from the TKN  originally in the sample as:  (TKN) x  4,57  =  potential NOD.



This compared favorably with the NOD measured using the  nitrification



inhibitor with an average difference of 0.9 mg/1 .  The results are



compiled in Table 5.  It should be  emphasized that  the potential  MOD



estimate from the TKN may not occur. However, the  coefficient of



linear correlation (r=0.88) suggested that  after 20 days of  incubation



nitrification was generally complete and that the method utilizing



TCMP gave reasonable NOD results.



Lehigh River  Study



     The inhibitor TCMP was also employed in an  intensive  nitrification



study undertaken on the Lehigh River during fall 1977.  The  study



included the  determination of nitrogen  states and dissolved  oxygen



depletion of unaltered and inhibited samples at  several  times  during



a long term incubation interval.  The data  are  presented in  Figure 3



and Tables 5 and 7 and reflect the  different sample types  and





preparations  involved:

     The average difference between the two NOD methods for river samples,
with an oxygen demand of less than 10 mg/1, was 0.4 mg/1  (n=12S and
s.d.=0.349).   The seeded effluent samples  had an average  ^!OD difference
of 0.5 mg/1  (n=42 and s.d.=0.463).  The increased error and variability
of the results reflects the added measurements of the seeded blank
made for both nitrogen conversions and oxygen depletion determinations.
The average NOD difference for seeded and  diluted effluent samples was
5.7 mg/1 (n=36 and s.d.= 7.83), which represented an average error
of 10% for the NOD.  The NOD error for diluted samples was amplified
by the dilution factors of 15 and 30 necessary for the BOO analysis.
A paired t-test of the nitrogenous oxygen  demand over the combined
206 paired data sets established at the 95% confidence level (t=.75)
that there was no significant difference  in the results of the two
NOD methods.
     Station 031, an industrial effluent  sample from a steel plant
slag leachate was unique in that the outfall had an average BOD2Q_3i|
of 763 mg/1 and an average initial TKN of 359 mg/1 on the three days
it was sampled.  However, nitrate and nitrite were not formed after 31
days of incubation.  The sample was analyzed for phenol and cyanide
and was found to contain 35.9 mg/1 total  phenol and 50 mg/1 cyanide.
This suggested that the outfall was toxic to nitrifying bacteria,
but not to the heterotrophic species present.

                               Conclusions
     The results  of this  study  on  synthetic,  river,  sewage  treatment
plant and industrial  effluent samples  suggested  that:
     1)  TCMP was an effective  inhibitor  to  nitrification.
         The; inhibitor stopped  the nitrification of  ammonia  by
         inhibiting the formation  of nitrite.
     2)  TCMP did not inhibit the  conversion  of  nitrite  to  nitrate.
     3)  TCMP did not inhibit the  respiration  of glucose.
     4)  TCMP did not significantly contribute to the  CBOD  even
         after 31 days of incubation at 20°C.
     5)  The determination of NOD  using the  difference in oxygen
         depletion in inhibited and uninhibited  BOD  bottles  was quick
         and easy.  This  method did not involve  the  expensive equipment,
         no1'* time associated with  the chemical analysis  of  nitrogen
         states to determine the MOD.
     6)  The inhibitor did not interfere  with the determination of
         oxygen by the azide modified Winkler or electrode  methods.
     7)  The inhibitor method yielded reliably accurate  NOD determinations

 16. ABSTRACT

   The nitrification  inhibitor,  N.-Serve was applied to long term BOD  tests  to
   determine the nitrogenous  oxygen demand.  This was compared to the NOD
   calculated from the N-series  conversions observed over the course  of  the
   incubation.  Preliminary inhibitor studies, involving measurement  of  N-series
   and variation of glucose concentration with time, were conducted on synthetic
   samples of glucose and/or  glutamic acid spiked with ammonia and/or.nitrite  to
   .assess  its affect  on  heterotrophic respiration and evaluate its accuracy and
   limitations.  Extensive  testing was then performed-on sewage treatment  plant
   effluents and on the  receiving waters of the Potomac and Lehigh Rivers.   It
   was found that this method of determining NOD:  was accurate; did  not affect-
   heterotrophic respiration; did not interfere with, dissolved oxygen measurements
   via the dissolved  oxygen probe or Vlinkler method; and was not applicable when
   nitrite was present in a significant amount.                      '
