INTRODUCTION
In response to public concern resulting from publicity about alleged toxic
organic compounds in the New Orleans, Louisiana and other municipal drinking
water supplies, Region V States asked for assistance in obtaining current data
concerning certain drinking water supplies in Region V. The study was designed
to provide frequency of occurrence and concentration values of volatile and
non-volatile organic compounds, selected pesticides, herbicides and fungicides,
polychlorinated biphenyl mixtures, certain phthalate esters, metals and other
inorganic parameters in drinking waters. Another interest was to establish
baseline concentrations for those organic compounds of health concern or thought
to result from chlorination, and therefore to be widely distributed in our water
supplies. These compounds include carbon tetrachloride (CC1.), chloroform (CHC13),
bromodichloromethane (BrCHClp), dibromochloromethane (BrpCHCl), bromoform (B^CH),
1,2-dichloroethane (Cl-C^-CI^-Cl), dichloromethane (CF^C^), aldrin, dieldrin
and DDT.
The 83 cities were selected jointly by both State and Federal personnel
to get a broad representation of Region V water supply systems. The study evalu-
ates organic pollution in drinking water supplies of most concern to State
agencies, provides appropriate background data for quality assurance purposes,
and complements the National Reconnaissance Survey in determining the concentra-
tions, sources, and potential danger of organic chemicals in drinking water.
A maximum number of parameters per sample were included to provide a com-
plete description of each water supply and to detect possible relationships -
between the more traditional inorganic parameters and the organic parameters of
current interest. In addition, since many expenses of the study, such as sampling
costs, report writing, instrument and other fixed capitol depreciations, trans-
portation, etc., remain constant, the most efficient study includes a maximum
number of parameter analyses per sample.

-------
It should be emphasized that this study occurred during winter months
when waters were cold, surface streams were generally at higher than normal
flows and contained considerable suspended solid materials, agricultural and
gardening activities were at a minimum as were certain industrial activities.
Therefore, concentrations could vary substantially from values reported in this
manuscript for samples collected at different times of the year.
1,2
Based on the data presented in Table I, it is clear that chloroform,
bromodichloromethane, dibromochloromethane and bromoform are consistently higher
in treated drinking water than in raw waters at most cities in the Region. The
-mean concentrations however are quite low.
Table II is a listing of the analytical results from which the summary
data in Table I were calculated. All concentrations are in micrograms per
liter (ug/lK It is the practice of the Central Regional Laboratory to report
detection limits based on each day's quality assurance data. Therefore, dif-
ferent detection limits are given for some parameters in Table II and other
places in this report.
Conclusions that may be reached from an examination of the data in
Table II are as follows:
a. Clear raw water results in finished water that is relatively free of
chloroform and related halogenated compounds. Of the 25 supplies
having the lowest concentrations of chloroform, 12 obtain their
water from the Great Lakes, 8 from deep wells and only 5 from
surface sources.
b. There is a correlation between concentrations of chloroform, bromo-
dichloromethane, dibromochloromethane, and bromoform in the
finished water. It appears they result from chlorination of precursors
in'the'raw water. Since there'is no'pattern to their occurrence,

in Table II are used, both ratio percentages and the scatter increase as
the measurements approach the detection limit
8
-------
it does not appear that carbon tetrachloride, methylene chloride or
1,2-dichloroethane are produced by a chemical reaction within the treat-
ment process,
c. Using only the "more accurate data (higher concentrations can be measured
more accurately than lower concentrations) for those cities having over
100 ug/1 of chloroform in their finished water, the concentration ratio
percentages [see Table III of BrCHCl2 to CHC13 range from 1.2% to 17%.
The range for the BrCHC^/B^CHCl ratios is 0 to 19$'. A careful examina-
tion of these ratios suggests that the concentration of BrCHCl2 will be
approcimately 13% that of CHC13 and the concentration of B^CHCl will be
about 6% that of BrCHCl2. This relatively constant ratio indicates a
common precursor or group of precursors of the halogenated pollutants.
Since the ratios described above are much higher than the ratio of
bromine to chlorine'-in the chlorine used to purify the raw waters, we
conclude that bromination is much faster than chlorination and that the
halogen is acting as an electrophile rather than a nucleophile during
the chemical reaction producing the subject pollutants. The ratios
for Fremont, Ohio; Bessemer Township, Michigan and certain other cities
do not follow this general pattern but have an excess of chloroform.
We suggest that a source of chloroform is 'operative that differs from
that of most cities studied. At first we suspected an industrial
discharge but that conclusion is inconsistent with a zero chloroform
concentration for the raw water. Therefore, these supplies may contain
a particularly reactive precursor for chloroform. Additional analytical
data will be required to identify any such precursor, to establish whether
or not these measured values are common throughout the year, and
9
-------
to suggest a .method of removal. It is suggested that check samples
Be collected to yertfy results that truly represent these water supplies.
The concentrations of brominated compounds are high relative to the
concentrations of chlorinated compounds for some cities. If this
pattern is repeated in check samples, and should the brominated com-
pounds be discovered to be of significance, the concentration of bromine
in the chlorine used for purification should be reduced.
d. The use of carbon treatment is not effective as was practiced by the
water treatment plants during the time of this study. (See Table IV)
We suspect that most of those cities presently using carbon have chosen
to do so to reduce taste and odor problems and that the carbon is much
•more effective in removing those compounds causing the water to have
a taste and odor than it is in removing the halogenated methanes or
other organic compounds that react to form chloroform.
Table IV summarizes water supply systems information. Data is reported as
it was obtained on field sheets at the time of sample collection. It can be noted
from this table that in addition to the characteristics of the raw water, chloro-
form production also depends upon the amount of chlorine applied. Another impor-
tant factor is the time of contact. For this study contact time must be considered
to be the entire elapsed time from chlorine application until sample analysis
0-5 days). Recent experiments with aliquots of southern Lake Michigan water that
were treated with 2 mg/1 of chlorine have shown chloroform production-to be cut in
half when the aliquots were again treated in one hour to remove all remaining
chlorine. Chlorine was allowed to react a number of days in the aliquots where
it was not removed after one hour.
2. Linear Regressions
Figures I, II, III, and IV show the linear regression equations and asso-
ciated F ratios calculated from the measurements for chloroform, bromodichlororaethane,
10
-------
dihromochJoronjetliane, and total cMo/ine dosage in river water systems, Since
the F value at tRe 0,01 probability point ts 7, the. null hypothesis of no rela-
tionship 1s rejected and it is concluded that significant correlation does exist
.between the parameters plotted on Figures I, II, III, and IV.
Further research should be directed to determining the rates of reactions
of the parameters analyzed in this study with particular attention to the source
of raw water used in treatment.

3. Pesticides, PCB's and Phthalates
Table V is a listing of those cities where pesticides, PCB's and/or
phthalates were identified. The other samples analyzed did not contain a detect-
able amount of any of the fifty pesticides included in the survey. All analytical
results are included in the appendix and from these we conclude that:
a. A large majority of the samples do not contain these types of compounds
in concentrations that can be measured with the procedures used for
this study.
b. For this class of compounds, the most commonly found are diethylhexyl-
phthalate, dieldrin, DDT, treflan, aldrin and hexochlorobenzene. The
concentrations of all pesticide type compounds identified to date
are low. The highest concentrations found were 68 nanograms per
liter (ng/1) for DDT, 11 ng/1 for dieldrin, 17 ug/1 for diethyl-
hexlphthalate and 50 ng/1 for treflan. All positive results are
given in Table V.
c. Concentrations of PCB's in those samples from Lake Michigan and the
Ohio River were too low to detect.
4. Non-Volatile Organic Compounds
Finished water was passed through small carbon filters used for sample
collection at Mt. Vernon, Evansville and Indianapolis, Indiana. Raw water samples
were also collected at Mt. Vernon. Presently the water from Whiting, Indiana
and Mt. Carmel, Illinois are being sampled for carbon filter and extraction
analyses. All of the exposed filters have been extracted with hexane, chloroform
and methanol. Each of the extracts has been separated in acidic, basic and
neutral fractions giving a total of nine concentrates per filter. The following
high boiling compounds have been identified in the Mt. Vernon and Evansville
supplies:

Many more of these high boiling compounds are present, but further purification
(we are attempting to accomplish the preparation by high pressure liquid chroma-
tography techniques) will be necessary to identify them. We have not yet
attempted to analyze the extracts for any low boiling compounds except for the
bis-2-chloroisopropyl and bis-2-chloroethyl ethers. Neither of these compounds
gave a gas chromatographic peak above the detection limit and therefore they
are not present to the extent they have been in Evansville samples analyzed
previously. In general, the current water samples from Evansville contain fewer
organic compounds than similar samples analyzed by the Region V laboratory and
Indiana State University-Evansville over the previous four years. This reduc-
tion in pollution is an expected product of the National Pollutant Discharge
Elimination System program and should reduce concern for Evansville water.
5. Inorganic Parameters
All samples were analyzed for the following fourteen metals: silver,
arsenic, calcium, cadmium, chromium, copper, iron, potassium, magnesium, man-
ganese, sodium, lead, selenium, and zinc. Concentrations (49 ug/1) of arsenic
were found at Kokomo, Indiana and prompted us to resample that plant. It was
subsequently found that Kokomo was using Wildcat Creek and several deep wells
as sources. The water from Wildcat Creek does not contain a measurable amount
of arsenic but water from two of the 15 deep wells contained up to 2000 ug/1.
This is apparently a very localized problem affecting only a few wells. With
proper treatment and blending the Kokomo Water Works has been able to maintain
25
-------
safe concentrations of arsenic in the finished drinking water. It is recommended
however that Kokomo analyze for the presence and quantity of arsenic in the
finished water at least once per month during periods when Wells #4 or #7 are
in use.
The arithmetic mean values for all finished water parameter concentrations
are less than drinking water standards with the exception of phenolics (Table VI &
VII). Since the detection limit of the analytical method used to measure phenol
concentrations is greater than the recommended levels, we do not interpret the
measured mean phenolic concentration to be significantly higher than the recom-
mended values.
Table VIII is an abbreviated frequency distribution of the finished water
(8)
data and shows that the Water Quality Criteria recommendations were occasionally
exceeded. In addition, the table shows the mean value for each parameter is
generally larger than the median value which indicates the data distribution
is log normal rather than gaussian. This point is illustrated in Figure 1.
It can be concluded from the data in Table IX that a high chemical oxygen
demand (COD) in the raw water is necessary for a high chloroform concentration
to result in the finished water. However, the converse is not always true as
some supplies had raw water COD's of 30 mg/1 or higher but CHCU concentrations
of 40 ug/1 or less. These data suggests that chloroform results from a single
or small group of compounds. They also support the concept that the chloroform
precursor reduces potassium dichromate and that those supplies having a low COD
need not be tested for chloroform.

Numberous drinking water plants add chemicals other than chlorine to the
during the treatment process. Two commonly used chemicals are ammonia
and polyphosphate. Fluoride is also added to many supplies.
Twenty-one (21) supplies added ammonia or ammonium ion to maintain
acceptable residual chlorine concentrations as chloramines. Nineteen (19) of
these supplies had ammonia - N concentrations above the median of 0.05 mg/1 for
finished water. The average increase of ammonia - N in finished versus raw
nater was 0.195 mg/1 for these supplies compared to the overall average of
zero (0) increase for all supplies (Table X).
Thirteen (13) supplies added polyphosphate. Twelve (12) of these supplies
ivere above the median finished water total phosphorus concentration. Also the
Dverall average change in phosphorus from raw to finished water was negative
D.01 mg/1. However, these 13 supplies averaged an increase of 0.168 mg/1.

Most supplies add fluoride. This is evident from the median fluoride
tration of 1.0 rag/1. However, 9 supplies apparently do not add fluoride.
Nine (9) supplies had pH values between 9.0 and 10.1. Of these supplies,
') also had CHCls concentrations greater than 50 ug/1. No additional rela-
n'ps were found.
Suspended solids removal was 90 percent based on the mean raw and finished
values. The highest suspended solids value for a finished water was 42 mg/1,
econd high was 13 mg/1, and all other values were 8 mg/1 or less. No positive
ilation exists between suspended solids and the presence of halogenated organic
Dunds. However, COO removal averaged only 50 percent indicating that signi-
it amounts of organic materials remained in the filtered water. This sug-
.s that the turbidity standard (suspended solids is the cause of turbidity)
not be sufficient to protect water supplies from halogenated organic compounds.
Economic Considerations
Table XI gives estimates of resources expended to complete this survey.
dollar estimates are based on the assumption that total expenses, including
overhead, costs $40,000 per position and a year contains 260 working days.
:. SIGNIFICANCE
It is not surprising that trace amounts of various organic chemicals can
detected in drinking water. With the sensitivity available in the gas
romatograph/mass spectrometer-computer equipment it is probable that many
ch compounds can be found in almost any facet of our environment that one
ooses to look. Absolute purity is only a theoretical term and is not attain-
3le in drinking water.
Concentrations that are above a normal background and that do pose a
ignificant health risk should of course be reduced. There are currently not
:nough data to fully understand either the normal background level or the health
iignificance of the organic compounds included in this study. However, with

perhaps the exception of chloroform, concentrations of organics analyzed in
these drinking waters should not be considered atypical. It is not likely that
they will be found to present a significant risk to health. Exposures to these
same compounds from ambient levels in other aspects of our environment (smoke,
air, food, medicines, etc.) can be expected to be much greater than that from
drinking water.
Chloroform, it appears, is affected by chlorine application. Concentra-
tions of chloroform in water supplies with a high chlorine demand may exceed
0.1 milligram per liter (mg/1). However, even at the highest concentration
found (0.366 mg/1), chloroform should not be considered to present an imminent
risk to health. There is no evidence that chloroform causes tumors in workers,
and the allowed occupational exposure to chloroform in air is over 100 times that
from drinking water with 0.5 mg of chloroform per liter.
The possibility must be recognized, however that traces of micropollutants
in drinking water may indeed contribute to the total exposure of persons to
environmental factors that contribute to carcinomas. An ad hoc Study Group of
EPA's independent Science Advisory Board in their May 1, 1975 report on the
health significance of drinking water chemicals, concluded that 1'some: health
risk exists." A portion of the Study Group's summary follows:
"Based upon recent, reasonably extensive, water quality data for
many U.S. water supplies and on extremely limited data from
experimental carcinogenesis studies, the Study Group concludes
that there may be some cancer risk associated with consumption
of "chloroform in drinking water. The level of risk, estimated
from consideration of the worst case and for the expected
cancer site for chloroform (the liver) might be extrapolated
to account for up to 40% of the observed liver cancer incidence .
rate. A more reasonable assumption, based upon current water
quality data which show much lower levels than the worst case in
the majority of U. S. drinking water supplies, would place the
risk of hepatic cancer much lower and possibly nil. Further,
it is emphasized that both the experimental carcinogen!city data
and the mathematical and biological extrapolation principles used
to arrive at the upper estimate of risk are extremely tenuous.
Epidemiologic studies do not, thus far, support the conclusion
of an increased risk of liver cancer; although hypothesisformulating
33
-------
studies in southern Louisiana suggest the possibility of an
association with contaminated water and overall high cancer
incidence. Critical definitive tests of this hypothesis have
not been conducted. Although some other organic contaminants
contained in the charge to the Study Group have carcinogenic
potential, the cancer risk to man is judged to be minor because
of their low concentration and/or infrequent occurrences in
drinking water."
IN SUMMARY: The study's findings do raise questions about the quality of
drinking water and there is a need for a better definition of the health rela-
tionships between these substances and man. At this point, though, there is
no evidence to justify quantum changes in current water treatment practices.
For example, EPA's statement from last November holds true . . . "the benefits
of continued use of chlorine for the disinfection of drinking water far out-
weigh the possible health risks from chlorine-derived organic compounds." While
trace organics in drinking water are an important problem which deserves investi-
gation, the situation today is not a crisis to be met with fear and precipitous
action.
IV. RECOMMENDATIONS
1. When wells contaminated with arsenic are used in Kokomo, the drinking
water should be monitored at least monthly to be certain that it
consistently meets drinking water standards. Appropriate precautions
should be taken before drilling any new wells in the area.
2. Since our results are based on individual grab samples collected at
what may not be normal conditions, the data may not reflect the long
term quality of any given supply. Therefore, the finished water of
those 31 supplies showing higher chloroform concentrations above
33 ug/1 should be re-analyzed for the volatile organic compounds and
selected metal and other inorganic parameters. In addition, a complete
organic compound analysis should be completed on as many of these water
supplies as possible.
34
-------
3. An effort should be made to identify the precursors) that react with
chlorine and bromine to produce the pollutants found in the finished
water samples. As a first step, raw waters should be analyzed com-
pletely and halogenation studies completed on potential precursors.
The best treatment for these pollutants may be removal of a precursor
rather than removal of the organic compounds found in the finished
water supplies. Raw water samples should be taken and analyzed com-
pletely at .those cities having the highest chloroform concentrations.
4. In addition to treatment methods involving carbon and ozone, aeration
should be looked at for removing volatile organic compounds.
5. The relationship of COD {or TOC) and CHC13 concentrations should be
further investigated to include raw water source comparisons and
other parameter correlations such as pH to act as indicators for
volatile organics.
V. SAMPLE COLLECTION, ANALYTICAL PROCEDURES AND QUALITY ASSURANCE
In general, all samples were collected, preserved and analyzed according
(3)
to recommended EPA procedures . In cases where official procedures have not
been recommended or approved, such as for the volatile organic and carbon filter
methods or where superior analytical methods have been developed as for the COD,
standard methods in current use in Region V were employed. All of these methods,
with corresponding quality assurance data that will permit the reader to estimate
the quality of data on a parameter or group of parameters basis are described
later in this section.

1. Sampling Procedures
Fourteen bottles of water were collected at each city. These
bottles were divided according to sample preservative as described
below. In all cases the bottles were filled completely to avoid an
air-liquid interface. Raw water samples were collected just prior to
chlorination. Finished water samples were collected several hours
after chlorination depending on plant flow.

Since these types of bottles had been in use in the Region for some
time and were known to be clean, they were not washed prior to sample
collection. However, to insure that results due to bottle contamination
or some other contamination were not reported, the normal set of reagent
-36
-------
blanks (preservative and distilled water in a sampling bottle) were
prepared daily by each sampling team and analyzed as the samples were
analyzed. No contamination problems associated with sampling were
detected.
The maximum holding times for the organic parameters are
unknown. Therefore, all organic samples were refrigerated upon
collection and either extracted or analyzed as quickly as possible
after sample collection; usually within forty eight hours but no
later than five days after sample collection. A laboratory standard
containing the seven volatile organics of interest was analyzed daily
during the study and remained stable for four weeks. Although chlor-
inated hydrocarbon pesticides are stable, other pesticides are known
to degrade with time so only minimum concentration values can be mea-
sured for these parameters.
All inorganic parameters were analyzed within those holding
times recommended for approval by Region V to the Methods Development
and Quality Assurance Research Laboratory, National Environmental
Research Center, Cincinnati, (Appendix I).
2. Volatile Organics
a) Analytical Procedures.
The procedure described below is a modification of methods
described by Kleopfer > for air studies and by Bellar and
(1 2)
Lichtenberg for volatile organics in water/ ' We have used
the experimental apparatus and organic trap described by Kleopfer,
the water sampling method of Bellar and Litchtenberg and have
37-
-------
developed our own gas chromatographic analytical techniques.
Quality Assurance data given at the end of this section shows
the procedure to give accurate results within the defined
experimental scatter.
Ten milliters of sample are transferred to a microware
centrifuge tube with a 14/20 ground glass joint from a com-
pletely filled glass sampling bottle. The centrifuge tube
is then placed on the debubbler apparatus held in place by
two springs as shown in Figure VI•

The needle of a trap that has been cleaned by being heated
to 135°C and flushed while hot with nitrogen is inserted into
the rubber septum. The stopcocks are opened permitting nitrogen
to flow through the debubbler, sample water and into the trap
where the organic compounds are adsorbed on the surface of the
Tenax. A nitrogen flow rate (Purge) of 80 ml/min for 8 minutes
is sufficient to quantitatively transfer those volatile organics
studied in this project. The trap is then removed and attached
to the gas chromatograph - desorption oven system as shown in

The trap is placed in the desorption oven with switch "A" (see
Figure 3) in the off position and left for 2 minutes while
thermal equilibrium is being established. The syringe needle
on the trap penetrates the GC injection septum as the trap is
placed in the desorption oven. At the end of the 2 minute
period, switch "A" is opened and the sample is carried into
-39-
-------
the GC column where a standard chromatographic analysis is
completed. Quantitative data are obtained by comparing the
recorder response of standard solutions to the response of
unknowns. Operating conditions of the chromatograph and
detector are as follows: oven temperature - 30°C for 3 min.
and then raised to 200°C at a rate of 20°C/min; injector
temperature - 200°C; detector oven temperature - 800 C;
nitrogen carrier gas flow rate - 40 ml/min; detector reducing
gas (h^) flow rate - 80 ml/min; desorption gas (Ng) flow
rate - 40 ml/min; column - 6' x 1/8" aluminum packed with
10% by weight FFAP on 60/80 Mesh Anakrom. A typical gas
chromatogram of a laboratory quality assurance control
standard is shown later.
b) 'Quality Assurance for Volatile Organics
Before any samples were analyzed for the presence of
halogenated volatile crganics, extensive analytical quality
control data was collected to optimize the analytical con-
ditions and to determine the reproducibility of the method.
Table XII lists the. responses given by the seven halogenated
organics included in this study as a function of purge time.
The purge gas flow rate was maintained at 80 ml/min during
investigation of the flow time. Preliminary work indicated
that longer purging times were required if the purge rate is
lowered. The data summarized in TableXII indicates that,
with a purging rate of 80 ml/min, a purge time of 8 min.
is optimum for the seven compounds of interest.
40
-------
Table .XIII summarizes the data obtained for a standard
mixture which was analyzed five different times (three
different traps were used to trap the volatiles). The
relative standard deviation is larger for methylene chloride
and carbon tetrachloride because of time limitations peak
heights instead of peak areas were used for quantification
check. Since methylene chloride and carbon tetrachloride
give broader and more poorly resolved peaks than the other
compounds investigated, a larger amount of scatter was
observed when the peak height was used for quantification
check.

Analytical quality control employed during analysis consisted
of routinely: 1) analyzing blank traps, 2) analyzing standards, 3) con-
firming the highest concentrations (10») qualitatively on the mass-
spectrometer and 4) collecting and analyzing 10% of the samples in
duplicate.
Blanks were analyzed at random throughout each day of the study.
A blank consisted of carrying out the complete analytical procedure
but leaving out the 10 ml of sample. Table XIV? summarizes the data
obtained for the blanks. It should be pointed out that the highest
blank values were obtained on two days when methylene chloride, carbon
tetrachloride and chloroform were being used as solvents in another
part of the laboratory and illustrates the sensitivity and extreme
care that must be used when performing these analyses. Figure VIII
shows the gas chromatogram of a typical blank.
Standards, made by dissolving approximately seven yl of a mix-
ture containing stoichiometric amounts of the seven halogenated organics
in 300 ml of water followed by diluting an aliquot of this to give a
final concentration in the 10 to 50 ug/1 range for each compound, were
analyzed at least three times a day (morning, noon and afternoon). The
average response factors were then used to calculate the concentration
of the samples. Fresh standards were made at least every 48 hours.
Fig .VIII also shows examples of chromatograms for a standard solution.
Even though the Coulson conductivity detector employed is
specific and warrants a high degree of confidence, over 10% of the
samples giving positive results were qualitatively confirmed using
gas chromatography - mass spectroscopy.

As an overall quality control check, approximately 13% of the
cities were sampled in duplicate. The analytical results for the dupli
cate samples are summarized in Table XV and defines for the reader
the precision of the total sample collection and analytical procedures
employed.
Fourteen samples were stored in a refrigerator after being
analyzed. A month later it was decided to re-analyze the samples.
The results are given in Table X-VI,. Only the data for CHC13, and
CHCIzBr are reported. The other five compounds of interest were below
detection limits. Since there was originally no intention of re-
analyzing the samples, they were not tightly stoppered nor were they
filled completely to the top (approximately 30 ml were removed when
the samples were first analyzed). This we believe is responsible for
the lower CHC13 values obtained at the latter date in those samples
containing higher chloroform concentrations. However, the data in
Table agrees in sufficient detail to augment the other AQC data
and to increase the credibility and the validity of the reported
sample concentrations. The data also indicate that refrigerated
samples can probably be preserved for over a month prior to analysis.

3. Pesticides, PCB's and Phthalates.
a) Introduction
The procedure used is based on "Methods for Organic
Pesticides in Water and Wastewater," 1971, EPA publication
from NERC - Cincinnati. The procedure differs from the
NERC's in that it has been expanded to include 47 pesti-
cides, 5 PCB mixtures and 2 phthalate esters. Also, the
gas chromatograph analysis step has been automated.
b) Experimental Procedures
The samples are received in glass quart bottles with
teflon lined screw caps and are transferred into clean two
liter separatory funnels. The first portion of the extract-
ing solvent is used to rinse out the sample bottle and then
is added to the separatory funnel. The samples are extracted
twice with 100 ml of 15% (v/v) ethyl ether /hexane, then
once with hexane, dried over NagSO^, and concentrated to about
5 ml in a Kuderna-Danish concentrator. The volume is reduced
to less than 4 ml using a stream of dry filtered air, diluted
to exactly 4 ml, and split into two 2 ml portions (I and II).
Portion (I) is spiked with phorate (2 yg), placed in a
2 ml vial fitted with a screw cap, and analyzed for phosphorus-
containing compounds. The analysis is performed on a Perkin-
Elmer model 900 gas chromatograph using a flame-photometric
(phosphorous mode) detector. This instrument is equipped with
50^
-------
an automatic sampler (adjusted for 10 yl injection) and a
PEP 1 G.C. data reduction system. A 6' x 1/4" glass column
packed with 14% SE-30 and 6% OV-210 on 80/100 mesh gas chrom
Q is used for the original analysis and a 6' x I/A" column
packed with 1.95% OV-17 and 1.5% 0V 210 on gas chrom Q 30/mo
mesh is used for confirmation. The gas chromatograph con-
ditions are as follows: inlet temperature - 250°C, detector
temperature -, 240°C, oven programmed from 200°C to 265°C at
4°/min, carrier gas - N2 at 60 ml/min.
Portion (II) is placed on a column of Florisil (18 q.
obtained from NERC, RTP, slurry packed with hexane) with 1/2"
of Na2$04 at the top and bottom of the florisil.
Two fractions are collected; the first is eluted with
200 ml of 6% ethyl ether in hexane, and the second with
200 ml of 50% ethyl ether in hexane. Each fraction is con-
centrated to less than 2 ml in the same manner as that used
for the extract, diluted to 2.0 ml with hexane, spiked with
Dieldrin (50% ether fraction) or Aldrin (6% ether fraction)
and placed in a 2 ml vial with a septum cap for GC analysis.
Each fraction from the Florisil column is analyzed using
a Perkin-Elmer 3920 gas chromatograph equipped with a two-
column injector splitter, automatic sampler with 10 ul syringe,
-51-
-------
two columns each leading to an electron capture detector,
and a PEP-1 data reduction system. The columns are both
6' x 1/4" glass. One is packed with 4% SE-30 and 6% OV-210
and the other with 1.95% OV-17 and 1.5% OV-210 on 80-100
mesh gas - chrom Q. The oven is maintained at 205°; the
carrier gas is 5% methane in argon for both columns.
A measured aliquot of each sample from the 6% ether
fraction which is thought to contain PCB's, as shown from
its chromatogram, is removed from the vial and placed onto_
a column of deactivated silicic acid (6 g, Bio-Rad Laboratories,
2.0% water content) which has been packed and washed with
60 ml hexane. The first fraction is eluted with hexane
(45 ml) and the second with 150 ml of a mixture of 80% methylene
chloride, 19% hexane, and 1% acetonitrile . Each fraction is
concentrated to less than 2 ml as previously described, diluted
with hexane to 2.0 ml, spiked with Dieldrin, and placed in a
vial for GC analysis. These fractions are analyzed for PCB's
and pesticides on the Perkin-Elmer model 3920 dual-column
electron capture system describe- above.
An overall flow diagram of the analysis scheme is shown
below with typical chromatograms and computer printouts for

c) Quality Assurance For Pesticide Analysis
In order to insure validity of the analytical results,
extensive analytical quality control was performed on each
step in the analytical scheme. Ten percent of the samples
were collected in duplicates for AQC purposes.
In the laboratory, samples were analyzed in groups. A
"blank" and a "spike" were analyzed with each group to provide
analytical quality control for that group. The "blanks"
and "spikes" were prepared using distilled water. The "spike"
contained a mixture of the 47 pesticides included in this
study. The concentrations of the various compounds in the
spike were in the 0 to 5 ug/1 range for the phosphate pesticides
and 20 to 200 ng/l range for the chlorinated pesticides. A
total of ten sets of "blanks" and "spikes" were analyzed. All
the AQC samples were treated in the identical manner as the
real samples were treated.
In order to evaluate the automatic gas chromatographic
system, standards were chromatographed at least every tenth
sample* This was used to monitor any change in the retention
time and/or in the response factor for each pesticide. If
changes were noted, the system was recalibrated and the samples
re-analyzed.
-59-
-------
Recovery data for the "spikes" are summarized in Table XVII
and relates to the reader the precision on a parameter
by parameter basis. None of the blanks indicated the
presence of pesticides above the detection limits. A normal
percentage of the samples collected in duplicate gave iden-
tical results within": the precision given in Table XX. The
only serious problem is the high recovery values for phthalates
which probably indicates contamination. We have reported
uncorrected phthalate concentrations with quality assurance
information to permit the reported data to be evaluated
by the user and urge each data user to use the phthalate
results with appropriate caution.

4. Non-Volati 1 c Orcjanics
a) Analytical Procedures
*) One liter Fim'r.hcd Water Grab Samples.
The 970-990 mi niters of sample not used to analyze
for volatile organics is preserved with 25 ml chloroform and
later poured into a one liter separatory funnel and ex-
tracted three times with 50 milliters of ethyl ether.
The combined extracts are dried over anhydrous sodium
sulfate and concentrated to approximately 0.2 ml in a
Kuderna-Danish evaporator. One to five microliters of
the concentrate are'injected into a gas chromatograph
equipped with a 6' x T/4-" glass column packed with 52
OV-101 and a flame ionization detector. Large peaks
observed in the chromatogram are identified with the
mass spectrometer. The list below shows compounds
identified using this technique. The phthalate esters
were found much more frequently than other compounds.
1. Phthalates: dioctyl, dibutyl, Bis(2-ethyl hexyl),
diethyl, dimethyl, ethyl and butyl.
2. Olecamide
3. Bis(2-ethyl hexyl} Adipate
4. Trichlorobenzene
5. Phenylphenol
6. Di-isobutyl Adipate
7. Butyl Phthalate butyl glycolate
-------
ii) Carbon Filter Samples
Carbon is extracted prior to being used for 24 hours with
hexane and 24 hours with methanol in a soxhlet extractor and
then placed in a glass filter equipped with teflon gaskets,
copper tubing and brass fittings. At no time does the incoming
water contact rubber type materials. All sampling equipment
is washed with soap and water overnight in an ultrasonic
cleaner> then with hexane and acetone prior to use. The
filters are placed on a common garden hose type faucet such
that water enters the bottom and flows out the top to a drain
as shown in Figure-XI-^- A carbon blank is treated in the same.
manner as carbon used to sample a water supply except for
passing sampling water through it.

-------
Since the adsorption and desorption efficiency on
carbon is not known for most organic compounds, quanti-
tative data can not be obtained and therefore only
approximate flow rates need to be obtained. These are
easily obtained by using a large (2-5 1) graduated
cylinder and stopwatch daily.during the sampling period.
Using a small stream of water, the sample volume per
week is usually between two and four thousand liters
for clean waters that do not significantly reduce
the flow by depositing foreign material in the filter.
The efficiency of adsorption is known to decrease as
the flow increases thus a greatly increased flow rate
may actually reduce the total quantity of material ad-
sorbed by the carbon. Carbon from the exposed filters
is transferred to a soxhlet and extracted for 24 hours
with hexane, 24 hours with chloroform and 24 hours with
methanol. Each extract is then divided into an acidic
basic and neutral fraction by standard techniques using
5%. HC1, 5% NaOH and the organic solvent used to extract
the solvent or toluene in the case of the methanol ex-
tract. The nine resulting extracts are dried over an-
hydrous sodium sulfate and concentrated to approximately
two millitersbefore a gas chromatographic and mass
spectrometric analysis is attempted. Experience to date

shows that the separations described above are usually
adequate for all except the neutral chloroform fraction,
which contains more compounds than can be separated using
gas chromatography. High pressure liquid chromatography
techniques for further purification of this fraction are
being investigated. Compounds identified to date are
shown below. Of significant interest is that bis-2-chloro-
ethy! and isopropyl ethers are below detection limits in
these samples.

a) Analytical Procedures
i) Flame Atomic-Absorption
Procedure
Standard flame atomic absorption procedures were
used for the determination of calcium, chromium, copper,
iron, magnesium, manganese, potassium, sodium, and zinc (3).
The reported results were obtained by direct aspiration
of water samples preserved with 0.5% concentrated nitric
acid. Thus the listed values represent metal concentra-
tions that were dissolved by the acid preservation, and
these will be equal to or lower than total metal concen-
trations as defined by the US EPA analytical procedures (3),
Analytical Quality Control
The accuracy and precision of the analytical
measurements were assessed by the use of duplicate samples,
spike recoveries, and intralaboratory control standards.
Data supporting the validity of the reported results and
that are pertinent to this study are listed in Tables XV111
XlX^and XX- - >;The listings are self-explanatory and show
that the determinations were performed with good accuracy
and precision.

•j-j) Flameless Atomic Absorption
Procedure
Flame!ess atomic absorption procedures were used
for the determination of arsenic, cadmium, lead, selemium,
and silver. The Perkin-Elmer HGA-2000 was utilized for
this purpose. This unit was mounted on a double-beam
atomic absorption spectrophotometer equipped with a deuterium
background corrector and interfaced to a strip chart re-
corder. The technique of standard additions was applied
exclusively for sample analysis. At least 3 working standards
and a reagent blank were prepared just prior to use from
commercial atomic absorption standard concentrates using
quality water and high purity acids. The instrumental
setup was optimized for the appropriate working range of
the element to be determined, and standards were checked
for linearity prior to use. Appropriate volumes (10-50
of sample and standard were injected and analyzed by pre-
viously established operating conditions. Linear working
curves (peak height vs. concentration) were extrapolated
graphically to zero absorbance for sample concentration
results. Samples outside the linear range were diluted.
In addition, acidities were closely controlled, since it
has been established in this laboratory that for certain

metals, i.e. arsenic, selemium, signal response is a
function of acid type and concentration.
Analytical Quality Control
Table XXI lists appropriate precision data based on the
analysis of duplicate samples. These results are consistent
with precision and accuracy ranges previously established
for this method. Data on recoveries and laboratory control
standards were not collected. The use of standard additions
provides points on the analytical working curve that are
in effect a measure of recovery.

B. Results and Discussion
Table XXII summarizes the ranges of metals found in the
water supplies covered by this study. The results reflect
the conformance of the finished drinking waters to the
proposed maximum allowable concentrations (6). One water
supply approaches the maximum suggested contamination level
for arsenic, and subsequent analytical data indicated that
this particular source was being polluted by supplemental
water originating from deep wells. In order to circumvent
potential problems, the mixing ratios of these two supplies
should be closely controlled or the use of the wells should
be discontinued , or the efficiency of the treatment plant
arsenic removal should be greatly increased.

6. Inorganic Parameters
a) Analytical Procedures
i) Ammonia - Technicon Co. method no. 154-71 W was modified
to analyze samples in the range 0-1 mg/1 P^-N. The method in-
volves a hypochlorite oxidation of an ammonia - phenol reaction
product using nitroprusside as a catalyst. The complexing reagent
and wash solutions were modified by the addition of 7.6 ml/1 of
10% NaOH and 1 ml/1 of concentrated sulfuric acid, respectively,
to compensate for the nutrient preservative.
ii) Alkalinity - Unaltered samples were titrated using an
automatic Fisher Titralyzer to an electrometrically determined
end-point of pH 4.5.
iii) Chloride - Technicon Co. method no. 9°-70 W was modified
to analyze samples in the range 0-200 mg/1 chloride by the addi-
tion of a twenty-five fold dilution loop. The method involves
the stoichiometric liberation of thiocyanate ion from mercuric
thiocyanate to form soluble but unionized mercuric chloride.
The free thiocyanate reacts with ferric ion to form ferric
thiocyanate proportional to the original chloride concentration.
iv) Chemical Oxygen Demand (COD) - The Central Regional
Laboratory semi-automated micro method was used to analyze the
drinking water samples for COD. Two and one-half ml of sample,
3.5 ml of sulfuric acid - silver sulfate solution and 2.5 ml of
potassium dichromate solution are added to 16 x ion mm borosili-
cate screw-top test tubes. The tubes are sealed with a teflon
-75-
-------
lined cap and then heated in an oven at 150°C for 2 hours.
The amount of Cr(III) produced by the oxidation of the
sample is proportional to the COO of the sample. The
appearance of Cr(III) is measured at 600 nm with Technicon
AA II equipment at 40 samples per hour. The method is
described in detail in Appendix II, which is a manuscript
that will appear in the July, 1975, issue of Analytical
Chemistry.
v) Cyanide - Technicon method no. 315-74W for cyanide
analysis was modified to improve sensitivity to lOOyg/1
full scale. The improvement was accomplished by addition
of a large diameter 13-turn coil to the manifold just be-
fore the colorimeter. The method involves an ultra-violet
digestion and distillation from acidic solution to separate
the cyanide from the sample matrix. Cyanide is converted
to cyanogen chloride by reaction with chloramine-T which
subsequently reacts with pyridine and barbituric acid to
give a red colored complex.
vi) Dissolved and Suspended Solids - The CRL micro
technique was used to' analyze the drinking water samples for
the residue parameters. Ten ml of sample were filtered
through a tared nuclepore filter and the residue weighed
to the nearest microgram to determine suspended solids. One
hundred microliters of filtrate was evaporated on 12 rm
aluminum pans and the residue weighed to the nearest inicro-
-76-
-------
gram to determine dissolved solids. A manuscript, submitted
for publication, describing the methods in detail is attached
as Appendix III.
vii) Fluoride - The EPA electrode method ("Manual of Methods
for Chemical Analysis of Water and Wastes", p. 65, 1974) for
fluoride was used without modification.
viii) Mercury - The CRL automated method was used for mercury
analysis. The method consists of a persulfate oxidation followed
by reduction with stannous chloride using hydroxylamine hydro-
chloride to reduce any residual chlorine present. The mercury
is detected by passing it through a 22 cm cell mounted in a
dual-wavelength spectrophotometer. A manuscript, submitted
for publication, describing the method is attached as Appendix
IV.
ix) Nitrate plus Nitrite - Technicon Co. method no. 100 -
70 W was modified by the addition of a 5 fold dilution loop
to analyze samples in the range of 0 - 5 mg/k NO 3 + NO;?-N.
In addition, the ammonium chloride buffer and wash solutions
were modified by adding 11.5 ml/1 of 102 NaOH and 1 ml/1 of
concentrated sulfuric acid, respectively, to compensate for
the nutrient preservative.. Nitrate plus nitrite is determined
by reducing the nitrate to nitrite with a copper-cadmium column.
The nitrite ion then reacts with sulfam'lamide at a low pH to
form a diazo compound. This compound then couples with N-l-
naph-thylethylene diamine dihydrochloride to form a reddish-
purple azo dye which is analyzed at 520 nm.
-77-
-------
x) Nitrite - Technicon method no. 102-70 X was used without
modification to analyze samples for nitrite. The analytical
method is the same as for nitrate plus nitrite except that the
copper-cadium column is deleted.
xi) pH - the pH of the drinking water samples was measured
with a pH meter equipped with a combination glass-reference
electrode.
xii) Phenolics - Technicon method no. 127 - 71 W for analysis
of phenolics was modified for samples in the range 0-200 mg/1.
The method involves the distillation of phenolics and the sub-
sequent reaction of the distillate with alkaline ferricyanide
and 4 - aminoantipyrene to form a red complex which is measured
at 505 nm.
xiii) Silica - Technicon Co. method no. 105 71 W was modified
by cutting the sample volume in half to analyze samples for
silica in the range 0-20 mg/1. This procedure for the deter-
mination of soluble silicates is based on the reduction of a
silicomolybdate complex in acidic solution to "molybdenum blue"
by ascorbic acid.
xiv) Specific Conductance - The specific conductivities were
measured with a Radiometer COM3 conductivity meter. The meter
is essentially an ohmmeter, calibrated in reciprocal ohms. A
built-in oscillator applies an ac voltage of suitable frequency
to the electrodes to avoid false readings from the polarization
of the solution.
-78-
-------
xv) Sulfate - Technicon Co. method no. 118-71 W was used
for sulfate analyses. The sample containing sulfate is passed
through a cation-exchange column to remove interferences and
then reacted with barium chloride and methylthymol blue. Barium
chloride and methylthymol blue are added in equal molar amounts
so the excess methylthymol blue corresponds to the sulfate con-
centration.
xvi) Total Phosphorus and Kjeldahl Nitrogen - The CRL methods
were used for the analysis of TP and TKN. Ten ml of samole were
mixed with 2 ml of the solution described in sections 6.2 and 6.3
of the 1974 EPA Methods Manual for TKN.^ The solution was
evaporated and then digested at 370°C for 1/2 hour. The digestate
was cooled and then diluted to 10 ml with distilled water. The
resulting solution was analyzed for phosphorus by Technicon Co.
method no. 155 - 71 W modified as follows: Five grams per liter
of sodium chloride was added to the manifold water line to com-
plex the mercury catalyst and avoid its reduction. Nitrogen
was analyzed as ammonia by the method described in paragraoh 1.
In addition, a five-fold dilution loop with 25 ml of 10 N NaOH
per liter was used for both methods. The sampler wash solution
consisted of 35 ml of concentrated sulfuric acid per liter. A
manuscript describing these methods in detail is being prepared.

Quality Assurance Procedures for Inorganic Parameters.
The accuracy and precision of the analytical data were assessed
by the use of daily instrument calibration and the analyses of duplicate
samples and intralaboratory quality control standards. The precision
and detection limit data in Table XXILIshow that all of the methods
used (with the exception of phenolics) are much more sensitive than
necessary when compared to the drinking water quality standards (Table XXIII),
SUMMARY
The Region V Drinking Water Study has satisfied most of the goals
of the project. It has provided the most complete list of parameter
concentration values yet reported for so large a group of water supplies.
These values were from samples collected approximately two months after
. (6)
the Safe Drinking Water Act became law and therefore they can be used
as baseline concentrations from which the effects of the Act can be
measured. The study clearly supports the conclusion drawn by Bellar &
2
Lichtenberg that the chlorination water treatment process produces
chloroform in finished drinking waters. It also provides experimental
evidence of the absence of most pesticides in our drinking water sup-
plies and where these compounds are present the concentrations are very
low. It showed that the waters at Evansville, Indiana are not now as
contaminated as they were a few years ago. Because we expect these
results to be used for a long period of time and to be rigorously
evaluated, we have made available a very limited number of copies of
all data. Appendix V is a complete listing of the field sheets as
they were received and Appendix VI is a complete set of analytical
results. Generally these appendices will not accompany this report.

The recommended sample holding times to be appearing in the next edition
of "Methods for Chemical Analysis of Water and Wastes," for some nutrient
and demand parameters, have caused great concern in Region V. The
Surveillance and Analysis Division has been preserving surface and waste-
waters with 1 ml H-pSQ^/l of sample for ammonia, nitrate plus nitrite,
total Kjeldahl nitrogen (TKN), total phosphorus, chemical oxygen demand
(COD), and total organic carbon (TOC) parameters since early 1973. All
samples to be analyzed for the above parameters are shipped via ground
transportation to the Central Regional Laboratory (CRL) in Chicago while
maintained.at.ambient temperature. In only a few cases have samples been
analyzed within tne 24 hour holding time you are recommending fcr the
above parameters. Typically, the holding times for sulfuric acid pre-
served samples have ranged from several days to approximately one month
from the time of sample collection.
The CRL has been actively investigating the preservation of samples since
January of this year. Although our results are preliminary we feel com-
pelled to release uhe data now before critically important administrative
decisions are being made. Our conclusions and recommendations which
follow are based on the sample types studied. All the data we have col-
lected are included in Attachment A.
Conclusions:
1) On the basis of our work, and data in the literature
(Howe and Holley, 1969; Charpiot, 1969; Oenkins, 1965)
we find no support for your recommended 24 hour holding
time for ammonia, nitrate plus nitrite, Kjeldahl nitrogen,
total phosphorus, and total organic carbon.
2) The recotmended holding time for TOC (24 hours) is incon-
sistent with the 7 day holding time for chemical oxygen
demand. Since the COD method inherently takes into
account the oxidation state of a waste, any sample insta-
bility will be reflected in the COD before the TOC. In
EPA F«»m 1320-4 (Re». 6.72)
-------

addition, on the basis of our experimental results the
recommended holding time of 7 days for COO measurement
is unnecessarily stringent.
3) The recommendation of one holding time for each para-
meter for all sample types is unnecessarily cautious.
Howe and Holley (1969) have shown that the greatest
cause of sample instability is biological activity.
Our work has verified this observation. The data in
Attachment A shov/s a tremendous difference in stability
between samples of high biological activity (raw sewage)
and lev/ activity (clean surface water).
Interm Recommendations For Holding Times
In all cases, the samples are assumed to be stored at room temperature.
As of yet, we have not found 2 ml/1(sulfuric acid / sample)to be any
more effective than 1 ml/1 so the latter procedure is also assumed.
1) Ammonia - At least one v/eek for raw sewage and one month
for surface waters and industrial wastes low in biologi-
cal activity.
2) Nitrate plus Nitrite - At least one month for all sample
types.
3} Total KJeldahl Nitrogen - At least one month for raw
sewage. For organic nitrogen follow ammonia recommenda-
tions.
4) Total and Dissolved Phosphorus - Up to two months for all
sample types.
5) COO/TOC - At least two v/eeks for raw sewage.
These holding times are based on preliminary data and are subject to modi-
fication pending the completion of one more study. However, they are sup-
ported by data from the literature and are much longer than yours. We
request that you make available to us any analytical data or literature
references that support your recommendations and hence contradict our
results. We believe our preliminary data are accurate and that our
interm recommendations outlined above should be accepted in Region V
pending further work. We would be most happy to have your input into
our one remaining preservation study and hope to discuss this matter
with members of the Quality Assurance evaluation team during the visit
to the CRL on October 15.

MICRO SEMI-AUTOMATED ANALYSIS OF SURFACE AND WASTEWATERS
FOR CHEMICAL OXYGEN DEMAND
PRELIMINARY
SUBJECT TO REVISION

-------
BRIEF
A micro semi-automated spectrophotometric method for determining the
chemical oxygen demand of surface and wastewaters is described and
compared to the standard method.
'ABSTRACT
A micro sample digestion technique for the determination of chemical
oxygen demand (COO) is described. An automated spectrophotometric
measurement of the appearance of chromium (III) after sample digestion
completes the method. Adequate sensitivity at 600 nm is achieved by
using a 50 mm flowcell to measure COD values in the range 3-900 mg/1.
The semi-automated method is compared to the standard method with
respect to precision, accuracy, ease of analysis and comparability of
data.

INTRODUCTION
The oxidation of organic and inorganic wastes in a receiv-
ing water depletes the dissolved oxygen supply, which can have
a profound effect on aquatic life (1). A meaningful determina-
tion of the natural oxygen demand of wastewaters has been a
problem since the previous century. The biochemical oxygen
demand (BOO) test was developed to measure the natural oxygen
demand of wastes under laboratory conditions similar to those
found in receiving waters (2-4). The advantage of the BOD test
1s that it is a good indicate/ of the bid-degradcbility of a
waste. The major disadvantages of the BOD test are the long
time required for analysis, the poor precision and the indeter-
minable accuracy of the method (4,5).
In order to substantially reduce the time required to esti-
mate the ultimate oxygen demand of a wastewater, the chemical
oxygen demand (COO) test was developed (6). The addition of
silver sulfate (7, 8) and mercuric sulfate (9) to the acidic
dichromate digestion solution, increased the readability of the
COD test (10, 11). However, since chemical oxidation does not
differentiate between biologically stable and unstable wastes, a
correlation between COD and 300 values must be developed for
each sample type (12). •
Stenger and Van Hall reported a very rapid method for measur-
ing the total organic carbon (TOC) content of water samples, which •
-------
- 3 -
4
can be related to oxygen demand (13). However, the advantage
1n being able to rapidly determine TOC values is offset by the
high initial equipment cost. In addition, the informational
content of the TOC analysis is less useful than that gained
from the BOO or COD methods (14). The TOC test does not dif-
ferentiate between compounds with the same number of carbon
atoms, but which are in different stages of oxidation and hence
have different oxygen demanding potentials. Since the COD and
BOD tests measure the amount of oxygen required to stabilize
waste sample's, their values inherently reflect the original
oxidation state of the chemical pollutants.
*
The standard COD test (4) is widely used because it pro-
vides a good balance between the value of the information gained
and the speed of analysis when compared to the BOD and TOC tests
(12). However, the standard method for determining COD has
limitations which are not inherent in the concept of the test.
The back-titration of dichromate after sample digestion is an
insensitive method of detection. This lack of method sensitiv-
ity has been partially alleviated by using two different concen-
trations of dichromate and a relatively large sample volume. In
addition, the consumption of large quantities of expensive rea-
gents, the extensive bench space requirement of the COD hot plates
which limits the number of analyses that can be performed in a
day, and the difficulty of disposing of Urge quantities of highly
acidic mercury, silver and chromium wastes, are serious problems
for most industrial laboratories (15).
-------
. 4 -
Recently, there has been considerable interest in simpli-
fying the rather tedious standard COO method (16-19). Unfortun-
ately, procedures using a much shortened digestion period or
*
lower digestion temperatures produce results equivalent to those
obtained by the standard method only for very readily oxidized
wastewaters (20-22).
Bloor (23) and Johnson (24) determined the organic content
of biological materials using dichromate as an oxidant and then
measuring the excess dichrcmate spectrophotometrically. This
procedure eliminated the tedious detection procedure of the stand-
4
ard method. The spectrophotometrfc procedure has been applied to
the analysis of water samples in which the COD was determined by
measuring the appearance of Cr (III) after manual digestion (25-27)
Several COD methods which use a spectrophotornetric means of
detection and automated sample digestion have also been reported.
Sample digestion was accomplished using a continuous digestor (28,
29) or high temperature bath (30-32). However, lift and Cain
reported data which show that these automated procedures do not
produce results equivalent to the standard method for all sample
types (33). The incomparability of data was attributed to incom-
plete sample oxidation caused by the short digestion times in the
automated methods. In addition, the higher concentration of sul-
furic acid used in most automated systems requires a smaller
amount of mercuric sulfate be used to avoid its precipitation in
-------
- 5 -
the sample lines and flowcell, The lesser amount of mercuric
sulfate caused chloride to be more of an interference in these
automated methods than in the standard method,
The method reported here combines the advantages of the
reliability of the standard digestion procedure (4), with the
superior sensitivity and precision of an automated procedure
based on the spectrcphotcmetric measurement of Cr (III) (27).
Use of the resultant micro semi-automated COO method has
Increased the productivity of this laboratory three-fold and
reduced the consumption of very expensive reagents and the
quantities of wastes twenty-fold.
EXPERIMENTAL
Apparatus. Samples were digested in Corning #9949 15x100
mm screwcap (cap #9998) culture tubes. Spectrophotometric measure-
ments were made with the apparatus shown schematically in Figure 1.
The automated system was fabricated using Technicon Corporation
AutoAnalyzer II equipment consisting of a Sampler IV, Pump III,
Colorimeter II, Recorder II, and single channel Digital Printer.
The colorimeter was used in the direct mode and equipped with 600
nm interference filters and 50 mm flowcells. The Standard Calibrra-
tion control was set at 228 to attain 1000 mg/1 COO full scale on
the recorder, A glass capillary was used as a sample probe. The
sampler was operated at 40 samples/hr with a 3:1, sample to wash
ratio.
-------
- 6 -
Wastewater samples with particulate matter-were blended
with a Teckmar Model SOT homogenizer before taking an aliquot
fop analysis. An adjustable 0-5 ml Oxford pipette with dis-
posable polypropylene tips was used for aliquoting samples and
addition of reagents.
Reagents. Unless otherwise noted, all chemicals were ACS
reagent grade. All reagent water was de-ionized and distilled.
Digestion solution was prepared by adding 10.216 g of
K2Cr207 (dried at 105° C), 167 ml of cone H2S04 and 33.3 g of
HgS04 to 500 ml of water and. diluting the cooled solution to
1 1.
Catalyst solution was prepared by dissolving 22 g of Ag2S04
in a 9-lb bottle of cone H2S04.
Sampler wash solution was 50% sulfuric acid by volurne.
A stock potassium acid phthalate solution, equivalent to
10 g/1 COD, was prepared by dissolving 8.500 g of a dried portion
Of NBS standard reference material 84 h in water and diluting to
1 1. Working standards of 25, 50, 75, 100, 250, 500 and 750 mg/1
COO were prepared by diluting 2.5, 5, 7.5, 10, 25, 50 and 75 ml
of stock solution to 1 1, respectively.
Procedures. It was necessary to wash all culture tubes and
screw caps with 202 H2S04 before their first use to prevent random
contamination.
Digestion was carried out by placing 2.5 ml of sample and 1.5
sil of digestion solution in a culture tube. Three and one half ml
-------
- 7 -
'of catalyst solution were added carefully down the side of the
culture tube so that the acid formed a layer on the bottom.
The tube was capped tightly and then shaken to mix the layers.
Two blanks and a set of standards were prepared in the same
manner and analyzed with each sample set.
All samples, blanks and standards were heated in an oven
at 150° C, which is the observed reflux temperature of 50% sul-
furic acid. After two hours the tubes were removed from the
oven, cooled, and placed in the Sampler IV tray.
The analytical manifold and reagents were set up as indi-
cated in Figure 1, Two digested blanks were analyzed at the
beginning of each sample set to zero the baseline. A mid-scale
standard was used to calibrate the recorder and printer (34).
Standards were rerun periodically during the course of an ana-
lysis run to assure that the system remained in calibration.
The COD value of unknown samples v/as obtained by direct print-
out. A typical recorder trace for standards is shown in Figure 2.
RESULTS AND DISCUSSION
Sample Digestion. It has been shown that COD procedures
using a shortened digestion period and/or a reduced digestion
temperature do not attain the same degree of sample oxidation as
the standard method (20-22, 33). Any alternate test procedure
used to analyze wastewaters for COD must produce results equiva-
lent to or better than the current standard method (35). There-
fora, to insure data comparability the temperature and length of
-------
- 8 -
.sample digestion and concentration of reagents used in the
standard method were adopted for use in the semi-automated
procedure described here (4),
Since the micro colorimetric detection technique required
only 2 ml of digested sample the quantities of sample and rea-
gents used were reduced twenty-fold in comparison to the
standard method (4, 11). Use of the standard COO digestion
apparatus was eliminated and instead all samples, blanks and
standards were digested in small screw-cap culture tubes. The
potential for sample contamination from large glass surfaces
was consequently reduced.
Screw caps with phenolic resin liners were found to be
unacceptable since they were attacked by the digestion solution
giving erroneously high COD values. Teflon-lined caps greatly
reduced this problem especially if each cap was used only onca.
Any sample tube which leaked, as evidenced by a black residue
on ths outside of the tube, -was discarded.
Uniform addition of reagents and improved precision was
achieved by dissolving all chemicals in one of two solutions.
The catalyst solution was prepared by the standard method (4).
The oxidizing solution v/as prepared by combining potassium
dichromate with mercuric sulfate and making the solution 5 N

was carefully -adjusted so as to avoid aspirating the precipitate.
Otherwise, aspiration of the particulate matter caused severe
baseline noise.
Spectrophotometric Analysis. The COD of wastewater samples
has been determined spectrophotornetrically, after digestion, by
measuring the decrease in Cr (VI) concentration at 352 (32) or
440 nm (19). Alternatively, the increase in Cr (III) concentra-
tionhas been measured at 600 (27) or 650 nm (25). All of these
authors found the Spectrophotometric procedure to be easier to
perform than the manual titration.
Molov and Zaleiko showed that better sensitivity could be
achieved by measuring the decrease in Cr (V!) concentration than
the increase in Cr (III) concentration (28). However, the preci-
sion of.,a method based on measuring the decrease in Cr (VI) absorb-
ance is very dependent on the reproducibility of reagent addition.
This problem was avoided and adequate sensitivity achieved by
measuring the appearance of Cr (II!) at 6GO mm, using a 50 mm
flowcell, and the scale expansion capability of the Technicon
colorimeter.
In order to increase the sensitivity of the standard method,
two different concentrations of oxidizing reagent are co.raonly
used, These correspond to tv/o levels of CCO measurement, 5-50
ing/1 and 50-3CO ~g/l (11). «!core and Walker found that the
working range cf the low level modification was limited by the
diminished oxidation potaniial of the digestion solution after
505 of the dichromata was consumed (36).
-------
- 10 -
Due to the adequate sensitivity of the spectrophotometric
semi-automated method, only one set of reagent concentrations
was necessary to cover both levels of the standard method. In
order to test the linearity of the semi-automated method, .
standards between 500 and 1000 mg/1 COD were analyzed in incre-
ments of 25 mg/1. Potassium hydrogen phthalate was chosen for
use as a standard because of its stability in solution and its
complete oxidation under the conditions of the COD test (4).
The results, presented in Figure 3, show the colorimetric method
to.be linear up to 900 mg/1 COD.
Due to the use of 50% sulfuric acid, the original automated
manifold was constructed with acidflex tubing. However, the
system exhibited very poor hydralic characteristics. This problem
was alev.iatsd by replacing the acidflex tubes with tygon pump
and transmission tubing. The recorder trace in Figure 2 was
undamped. The entire system was cleaned for about 1/2 hour before
first use with 5Q£ sulfuric acid to prevent severe baseline drift
due to Teachable organic matter. Also 1:1 dilution loop was added
to the system to reduce tha viscosity cf the sample stream so that
proper debubbling occurred in the flcwcell.
Precision, Acc'jr^cy and Detection Limit. Since it was dif-
ficult to corract the semi-autcrcated results for r.he sirall baseline
drift, the working detection limit was defined as the mean bias of
the blank plus :v/o standard deviations. Eleven blank samples
were analyzed to detamina the detection limit. The mean value
-------
-11 -
'obtained was 1 mg/1 with a standard deviation of 0.8 mg/1 COD.
These values were used to define the detection limit at 3 mg/1
COD. This number compares quite favorably with the detection
limit of 5 mg/1 COD reported by Moore and Walker for the Tow
level standard COD method (36).
The relative precision of both modifications of the stand-
ard and the semi-automated COD methods was determined by perform-
ing replicate analyzes on four wastewater samples. Since the
standard and semi-automated determinations were performed at
different times, two similar sets of water samples were chosen
so that the relative standard deviations could be meaningfully
compared. The relative standard deviations of both methods for
low COD concentrations, as shown in Table I, compare very closely.
However, the precision of the semi-automated method at high COD
concentrations was approximately seven times better than the
standard method.
Adelman pointed out that one of the factors contributing to
the poor precision of the standard method was the potential loss
of volatile components of the wastewater samples (30). This can
be caused by the heat generated by the mixing of the sample with
the concentrated acid prior to reflux or during the reflux step.
This problem was eliminated in the semi-automated procedure by
avoiding mixing the sample and acid layers until the tube is
capped and the fact that sample digestion occurs in a completely
closed system.
-------
- 12 -
The authors found that the ability to take-a representative
aliquot of a nonhomogeneous sample was the limiting component of
analysis variability regardless of method. Precision data for
the standard COD method determined from inter-laboratory analyses
of standard-like solutions must be regarded only as a lower limit
(5, 37).
The accuracy of the semi-automated method was determined by
measuring the recovery of standard addition of potassium hydrogen
phthalate to several types of water samples." The mean recovery
from 14 water and wastewater samples, shown in Table II, was 101%
with a standard deviation of 4*.
Comparison of Semi-Automated and Standard Methods. A variety of
surface and wastewater samples were analyzed by both the standard
and semi-automated COO methods to determine the comparability of
data. These samples included raw and treated sewage, industrial,
chemical and food process wastes. Results comparing the two methods
are shown in Table III. Initially the largest discrepancies between
methods occurred in samples which contained large quantities of
particulate matter, e.g., raw sewage. Homogenizing samples of
this type greatly improved the comparability of the data. Within
the standard deviation of the mean ratio of results, no significant
bias in COO values exists between methods.
In addition, several pure organic compounds were analyzed to
determine if the semi-automated method achieved a more complete
-------
- 13 -
digestion than the standard method. The experimental results
and calculated maximum theoretical COD values are shown in
Table IV. The semi-automated values were slightly higher than
the standard method results indicating that the former method
achieved a more complete sample digestion. The difference
could also be due to the fact that no volatile material can
excape from the sealed tubes during oxidation in the semi-auto-
mated method, while in the standard method, volatile material
may escape before sample oxidation is complete.
' 'Interferences. One of the major problems encountered in
other automated COD methods is the inability of the techniques
•
to compensate for the positive interference caused by the oxida-
tion of chloride present in wastewater samples (28-32). The
standard procedure for eliminating the chloride interference is
*
the addition of mercuric sulfate to form a complex and prevent
Its oxidation {4, 9). Experiments performed by this laboratory
indicate that no interference results up to 2000 mg/1 chloride
'when the standard procedure is used (9).
In other automated techniques, the high acid concentration
reduces the solubility of HgSQ4 so that the quantity of Hg(II)
1n solution is not sufficient to complex the same amount of
chloride as in the standard method (23-32),
In the semi-automated COD method, the ratio of HgS04 to
sample volume is identical to the standard method. Standards of
500 mg/1 CCD were spiked with varying amounts of chloride in
-------
- 14 -
order to determine the limiting concentration at which the inter-
ference was significant. The results, shown in Figure 4, indi-
cate that chloride does not interfere below 1000 rag/1. Above
this concentration, some precipitation occurs when the dilution
water combines with the sample stream in the automated system,
which results in a noisy recorder trace. If it is necessary to
routinely analyze samples containing between 1000 and 2000 mg/1
chloride, the dilution loop can be removed. Air spikes will then
appear at the beginning and end of each sample peak, due to
improper debubbling, but the results are not affected.
Any chemical species remaining after sample digestion, which
absorb at 600 nm, cause a positive interference in the semi-auto-
mated method. Since almost all organic matter is digested by the
COD technique the possible interference from organic compounds
was not considered (6, 8, 36).
The presence of Cr (III) in a water sample gives an apparent
COD of 1.39 times the concentration of chromium. Also, a potential
Interference from iron was investigated by spiking standards of
500 mg/1 COO with increasing amounts of ferric iron. The results,
presented in Figure 5, show no apparent COO below 5 g/1 Fe. The
positive bias caused by high concentrations of interfering sub-
stances is routinely eliminated by diluting samples prior to
analysis or correcting the reported COO values from independent
determinations of chromium, iron and chloride.

BRIEF
A micro semi-automated spectrophotometric method for determining the
chemical oxygen demand of surface and wastewaters is described and
compared to the standard method.
'ABSTRACT
A micro sample digestion technique for the determination of chemical
oxygen demand (COO) is described. An automated spectrophotometric
measurement of the appearance of chromium (III) after sample digestion
completes the method. Adequate sensitivity at 600 nm is achieved by
using a 50 mm flowcell to measure COO values in the range 3-900 mg/1.
The semi-automated method is compared to the standard method with
respect to precision, accuracy, ease of analysis and comparability of
data.

INTRODUCTION
The oxidation of organic and inorganic wastes in a receiv-
ing water depletes the dissolved oxygen supply, which can have
a profound effect on aquatic life (1). A meaningful determina-
tion of the natural oxygen demand of wastewaters has been a
problem since the previous century. The biochemical oxygen
demand (SOD) test was developed to measure the natural oxygen
demand of wastes under laboratory conditions similar to those
found in receiving waters (2-4). The advantage of the BOD test
1s that it is a good indicator of the bio-degradcbility of a
waste* The major disadvantages of the BOD test are the long
time required for analysis, the poor precision and the indeter-
minable accuracy of the method (4,5).
In order to substantially reduce the time required to esti-
mate the ultimate oxygen demand of a wastewater, the chemical
oxygen demand (COD) test was developed (6). The addition of
silver sulfate (7, 8) and mercuric sulfate (9) to the acidic
dichromate digestion solution, increased the real lability of the
COD test (10, 11), However, since chemical oxidation does not
differentiate between biologically stable and unstable wastes, a
correlation between COD and BOD values must be developed for
each sample type (12). •
Stenger and Van Hall reported a very rapid method for measur-
ing the total organic carbon (TCC) content of water samples, which
-------
- 3 -
«
can be related to oxygen demand (13). However, the advantage
*
1n being able to rapidly determine TOC values is offset by the
high initial equipment cost. In addition, the informational
content of the TOC analysis is less useful than that gained
from the BOO or COD methods (14). The TOC test does not dif-
ferentiate between compounds with the same number of carbon
atoms, but which are in different stages of oxidation and hence
have different oxygen demanding potentials. Since the COD and
BOD tests measure the amount of oxygen required to stabilize
waste samples, their values inherently reflect the original
oxidation state of the chemical pollutents.
*
The standard COD test (4) is widely used because it pro-
vides a good balance between the value of the information gained
and the speed of analysis when compared to the BOD and TOC tests
(12). However, the standard method for determining COD has
limitations which are not inherent in the concept of the test.
The back-titration of dichromate after sample digestion is an
Insensitive method of detection. This lack of method sensitiv-
ity has been partially alleviated by using two different concen-
trations of dichromate and a relatively 1'arge sample volume. In
addition, the consumption of large quantities of expensive rea-
gents, the extensive bench space requirement of the COD hot plates
which limits the number of analyses that can be performed in a
day, and the difficulty of disposing of large quantities of highly
acidic mercury, silver and chromium wastes, are serious problems
for most industrial laboratories (15).
-------
• 4 -
Recently, there has been considerable interest in simpli-
fying the rather tedious standard COD method (16-19). Unfortun-
ately, procedures using a much shortened digestion period or
•
lower digestion temperatures produce results equivalent to those
obtained by the standard method only for very readily oxidized
wastewaters (20-22).
Bloor (23) and Johnson (24) determined the organic content
of biological materials using dichromate as an oxidant and then
measuring the excess dichromate spectrophotometrically, This
procedure eliminated the tedious detection procedure of the stand-
4
ard method. The spectrophotcmetric procedure has been applied to
the analysis of water samples in which the COO was determined by
measuring the appearance of Cr (III) after manual digestion (25-27)
Several COD methods which use a spectrophotometric means of
detection and automated sample digestion have also been reported.
Sample digestion was accomplished using a continuous digester (28,
29) or high temperature bath (30-32). However, Tift and Cain
reported data which show that these automated procedures do not
produce results equivalent to the standard method for all sample
types (33). The incomparability of data was attributed to incom-
plete sample oxidation caused by the short digestion times in the
automated methods. In addition, the higher concentration of sul-
furic acid used in most automated systems requires a smallsr
amount of mercuric sulfate be used to avoid its precipitation in
-------
- 5 -
the sample lines and flowcell. The lesser amount of mercuric
sulfate caused chloride to be more of an interference in these
automated methods than in the standard method,
The method reported here combines the advantages of the
reliability of the standard digestion procedure (4), with the
superior sensitivity and precision of an automated procedure
based on the spectrophotometric measurement of Cr (III) (27).
Use of the resultant micro semi-automated COO method has
Increased the productivity of this laboratory three-fold and
reduced the consumption of very expensive reagents and the
quantities of wastes twenty-fold,
EXPERIMENTAL
Apparatus. Samples were digested in Corning £9949 16x100
mm screwcap (cap £9998) culture tubes. Spectrophotometric measure-
ments were made with the apparatus shown schematically in Figure 1.
The automated system was fabricated using Technicon Corporation
AutoAnalyzer II equipment consisting of a Sampler IV, Pump III,
Colorimeter II, Recorder II, and single channel Digital Printer.
The colorimeter was used in the direct mode and equipped with 600
nm interference filters and 50 mm flowcells. The Standard Calibrra-
tion control was set at 228 to attain 1000 mg/1 COO full scale on
the recorder. A glass capillary was used as a sample probe. The
sampler was operated at 40 samples/hr with a 3:1, sample to wash
ratio.

Wastewater samples with particulate matter-were blended
with a Teckmar Model SDT homogenizer before taking an aliquot
for analysis. An adjustable 0-5 ml Oxford pipette with dis-
posable polypropylene tips was used for aliquoting samples and
addition of reagents.
Reagents. Unless otherwise noted, all chemicals were ACS
reagent grade. All reagent water was de-ionized and distilled.
Digestion solution was prepared by adding 10.216 g of
K2Cr207 (dried at 105° C), 167 ml of cone H2S04 and 33.3 g of
HgSC>4 to 500 ml of water and. diluting the cooled solution to
1 1.
Catalyst solution was prepared fay dissolving 22 g of Ag2S04
in a 9-1b bottle of cone H2S04.
Sampler wash solution was 50% sulfuric acid by volume.
A stock potassium acid phthalate solution, equivalent to
10 g/1 COD, was prepared by dissolving 8.500 g of a dried portion
of NBS standard reference material 84 h in water and diluting to
1 1. Working standards of 25, 50, 75, 100, 250, 500 and 750 mg/1
COD were prepared by diluting 2.5, 5, 7.5, 10, 25, 50 and 75 ml
of stock solution to 1 1, respectively.
Procedures. It was necessary to wash all culture tubes and
screw caps with 202 H2SO^ before their first use to prevent random
contamination.
Digestion was carried out by placing 2.5 ml of sample and 1.5
ail of digestion solution in a culture tube. Three and one half ml
-------
- 7 -
of catalyst solution were added carefully down the side of the
culture tube so that the acid formed a layer on the bottom.
The tube was capped tightly and then shaken to mix the layers.
Two blanks and a set of standards were prepared in the same
manner and analyzed with each sample set.
All samples, blanks and standards were heated in an oven
at 150° C, which is the observed reflux temperature of 50* sul-
furic acid. After two hours the tubes were removed from the
oven, cooled, and placed in the Sampler IV tray.
The analytical manifold and reagents were set up as indi-
cated in Figure 1. Two digested blanks were analyzed at the
beginning of each sample set to zero the baseline. A mid-scale
standard was used to calibrate the recorder and printer (34).
Standards ware rerun periodically during the course of an ana-
lysis run to assure that the system remained in calibration.
The COD value of unknown samples was obtained by direct print-
out. A typical recorder trace for standards is shown in Figure 2.
RESULTS AND DISCUSSION
Sample Digestion. It has been shown that COD procedures
using a shortened digestion period and/or a reduced digestion
temperature do not attain the same degree of sample oxidation as
the standard method (20-22, 33), Any alternate test procedure
used to analyze wastawatars for COD must produce results equiva-
lent to or better than the current standard method (35). There-
fore, to insure data comparability the temperature and length of
-------
- 8 -
.sample digestion and concentration of reagents used in the
standard method were adopted for use in the semi-automated
procedure described here (4).
Since the micro colorimetric detection technique required
only 2 ml of digested sample the quantities of sample and rea-
gents used were reduced twenty-fold in comparison to the
standard method (4, 11). Use of the standard COO digestion
apparatus was eliminated and instead all samples, blanks and
standards were digested in small screw-cap culture tubes. The
potential for sample contamination from large glass surfaces
was consequently reduced.
Screw caps with phenolic resin liners were found to be
unacceptable since they ware attacked by the digestion solution
giving erroneously high COD values. Teflon-lined caps greatly
reduced this problem especially if each cap -.vas used only once.
Any sample tube which Isakad, as evidenced by a black residue
on the outside of the tube, was discarded.
Uniform addition of reagents and improved precision was
achieved by dissolving f.ll chemicals in one of two solutions.
The catalyst solution was prepared by the standard method (4).
The oxidizing solution was prepared by combining potassium
dichromate with mercuric sulfate and making the solution 5 N
with sulfuric acid ~o solufailize the mercury salt. However,
the mercuric sulfata .-.as not completely soluble in the cooled,
combined reaction Tnx;ure. 7ha height of the sampler probe
-------

was carefully 'adjusted so as to avoid aspirating the precipitate.
Otherwise, aspiration of the participate matter caused severe
baseline noise.
Spectroohotometric Analysis. The COD of wastewater samples
has been determined spectrophotometrically, after digestion, by
measuring the decrease in Cr (VI) concentration at 352 (32) or
440 nm (19). Alternatively, the increase in Cr (III) concentra-
tionhas been measured at 600 (27) or 650 nm (25). All of these
authors found the spectrophotometric procedure to be easier to
perform than the manual titration.
Molov and Zaleiko showed that better sensitivity could be
achieved by measuring the decrease in Cr (VI) concentration than
the increase in Cr (III) concentration (28). However, the preci-
sion of ..a method based on measuring the decrease in Cr (VI) absorb-
ance is very dependent on the reproducibility of reagent addition.
This problem was avoided and adequate sensitivity achieved by
measuring the appearance of Cr (III) at 603 rrm, using a 50 mm
flowcell, and the scale expansion capability of the Techm'con
colorimeter.
In order to increase the sensitivity of the standard method,
two different concentrations of oxidizing reagent are coraionly
used. These correspond to tv/o levels of CCD measurement, 5-50
mg/1 and 5C-3CO nig/1 (11). Moore and Walker found that the
working range cf the low level modification was limited by the
diminished oxidation pccan-ia! of the digestion solution after
50* of the dichrcmata was consumed (35).
-------
- 10 -
Due to the adequate sensitivity of the spectrophotometric
semi-automated method, only one set of reagent concentrations
was necessary to cover both levels of the standard method. In
order to test the linearity of the semi-automated method, .
standards between 500 and 1000 mg/1 COD were analyzed in incre-
ments of 25 mg/1. Potassium hydrogen phthalate was chosen for
use as a standard because of its stability in solution and its
complete oxidation under the conditions of the COD test (4).
The results, presented in Figure 3, show the colorimetric method
to.be linear up to 900 mg/1 COD.
Due to the use of 50* sulfuric acid, the original automated
manifold was constructed with acidflex tubing. However, the
system exhibited very poor hydra!ic characteristics. This problem
was alev.iatsd by replacing the acidflex tubes with tygon purnp
and transmission tubing. The recorder trace in Figure 2 was
undamped, The entire system was cleaned for about 1/2 hour before
first use with 50* sulfuric acid to prevent severe baseline drift
due to leachable organic matter. Also 1:1 dilution loco was added
to the system to reduce the viscosity of the sample stream so that
proper debubbling occurred in the flowcsll.
Precision, Accuracy ;nd Detection Limit, Sir.ca it was dif-
ficult to correct the semi-automated results for the "an baseline
drift, the working detection limit was defined as the mean bias of
the blank plus two standard deviations. Eleven blank samples
were analyzed to determine the detection limit. The mean value
-------
- n -
'obtained was 1 mg/1 with a standard deviation of 0.8 mg/1 COD.
These values were used to define the detection limit at 3 mg/1
COD. This number compares quite favorably with the detection
limit of 5 mg/1 COD reported by Moore and Walker for the low
level standard COD method (36).
The relative precision of both modifications of the stand-
ard and the semi-automated COD methods was determined by perform-
ing replicate analyzes on four wastewater samples. Since the
standard and semi-automated determinations were performed at
different times, two similar sets of water samples were chosen
so that the relative standard deviations could be meaningfully
compared. The relative standard deviations of both .methods for
low COD concentrations, as shown in Table I, compare very closely.
However; the precision of the semi-automated method at high COD
concentrations was approximately seven times better than the
standard method.
Adelman pointed out that one of the factors contributing to
the poor precision of the standard method was the potential loss
of volatile components of the wastewater samples (30), This can
be caused by the heat generated by the mixing of the sample with
the concentrated acid prior to reflux or during the reflux step.
This problem was eliminated in the semi-automated procedure by
avoiding mixing the sample and acid layers until the tube is
capped and the fact that sample digestion occurs in a completely
closed system.
-------
- 12 -
The authors found that the ability to take-a representative
aliquot of a nonhomogeneous sample was the limiting component of
analysis variability regardless of method. Precision data for
the standard COO method determined from inter-laboratory analyses
of standard-like solutions must be regarded only as a lower limit
(5, 37).
The accuracy of the semi-automated method was determined by
measuring the recovery of standard addition of potassium hydrogen
phthalate to several types of water samples'. The mean recovery
from 14 water and wastewater samples, shown in Table II, was 101%
with a standard deviation of 4%.
Comparison of Semi-Automated and Standard Methods. A variety of
surface and wastewater samples were analyzed by both the standard
and semi-automated COD methods to determine the comparability of
data. These samples included raw and treated sewage, industrial,
chemical and food process wastes. Results comparing the two methods
are shown in Table III. Initially the largest discrepancies between
methods occurred in samples which contained large quantities of
particulate matter, e.g., raw sewage. Homogenizing samples of
this type greatly improved the comparability of the data. Within
the standard deviation of the mean ratio of results, no significant
bias in COO values exists between methods,
In addition, several purs organic compounds were analyzed to
determine if the semi-automated method achieved a more ccmolete
-------
- 13 -
digestion than the standard method. The experimental results
and calculated maximum theoretical COD values are shown in
Table IV. The semi-automated values were slightly higher than
the standard method results indicating that the former method
achieved a more complete sample digestion. The difference
could also be due to the fact that no volatile material can
excape from the sealed tubes during oxidation in the semi-auto-
mated method, while in the standard method, volatile material
may escape before sample oxidation is complete.
' 'Interferences. One of the major problems encountered in
Other automated COD methods is the inability of the techniques
*
to compensate for the positive interference caused by the oxida-
tion of chloride present in wastewater samples (28-32). The
standard procedure for eliminating the chloride interference is
the addition of mercuric sulfate to form a complex and prevent
Its oxidation (4, 9). Experiments performed by this laboratory
Indicate that no interference results up to 2000 mg/1 chloride
when the standard procedure is used (9).
In Bother automated techniques, the high acid concentration
reduces the solubility of HgS04 so that the quantity of Hg(II)
1n solution is not sufficient to complex the same amount of
chloride as in the standard method (23-32).
In the semi-automated COD method, the ratio of HgS04 to
sample volume is identical to the standard method. Standards of
500 mg/1 COD were spiked with varying amounts of chloride in
-------
- 14 -
order to determine the limiting concentration at which the inter-
ference was significant. The results, shown in Figure 4, indi-
cate that chloride does not interfere below 1000 mg/1. Above
this concentration, some precipitation occurs when the dilution
water combines with the sample stream in the automated system,
which results in a noisy recorder trace. If it is necessary to
routinely analyze samples containing between 1000 and 2000 mg/1
chloride, the dilution loop can be removed. Air spikes will then
appear at the beginning and end of each sample peak, due to
Improper debubbling, but the results are not affected.
Any chemical species remaining after sample digestion, which
absorb at 600 nm, cause a positive interference in the semi-auto-
mated method. Since almost all organic matter is digested by the
COO technique the possible interference from organic compounds
was not considered (5, 8, 36).
The presence of Cr (III) in a water sample gives an apparent
COO of 1.39 times the concentration of chromium. Also, a potential
interference from iron was investigated by spiking standards of
500 mg/1 COO with increasing amounts of ferric iron. The results,
presented in Figure 5, show no apparent COO below 5 g/1 Fe. The
positive bias caused by high concentrations of interfering sub-
stances is routinely eliminated by diluting samples prior to
analysis or correcting the reported COO values from independent
determinations of chromium, iron and chloride.

ABSTRACT
An automated method for the determination of total as well as
inorganic and organic mercury by the cold vapor method is given. The
method is suitable for the analysis of samples in a variety of environ-
mental water matrices. A detection limit of 0.05 yg/1 is obtained by
the use of a highly sensitive spectrometer. The method is suitable
for the analysis of samples with mercury concentrations in the range
0.05 - -6 yg/1 and a COD less than 700 mg/1. The use of potassium per-
sulfate, potassium permanganate, potassium dichromate and mixtures of
these salts as oxidizing agents for the digestion step is discussed,
and a study of sample preservation is given. Twenty samples and/or
standards per hour can be analyzed using this method.

INTRODUCTION
In recent years a number of methods have been introduced for
1-10
the determination of mercury in a variety of matrices. The most
widely used method utilizes a flameless atomic absorption technique
10
first introduced by Hatch and Ott. Most of these are time consuming,

however, and do not allow for the analysis of a large number of samples,
such as is generally encountered by environmental laboratories. The
solution to this problem has been to move in the direction of establishing
automated procedures, which will allow either continuous monitoring or
the analysis of reasonable numbers of samples per day. This increase
-------
in the sample analysis rate should be done without affecting either
the sensitivity or the accuracy of the procedure.

very low content of oxidizable materials. However, for samples with a
high content of particulate matter as well as for those with high con-
centrations of oxidizable impurities, the suitability of these methods
is questionable. An automated method that addresses itself to these
questions is presented in this paper. The comparability of the des-
cribed method has been checked against the manual method presently
m
accepted by EPA and has been found suitable for the analysis of mercury
in all types of water samples including those samples with a high content
of particulate matter and oxidizable impurities.

EXPERIMENTAL
Apparatus. All glassware used In this work was borosilicate
glass. Standard mercury solutions were prepared in volumetric flasks
with glass stoppers. All glassware was first washed with water, soaked
for two hours in a 1% potassium permanganate solution, soaked for an
additional two hours in a 1:1 mixture of concentrated nitric and sul-
furic acids, and then washed with doubly deionized water. The glass-
ware was then baked for 3-4 hours at 400°C. It was found that for
subsequent use of the same glassware, a rinse with cone. HNO-j followed
by several rinses with doubly deionized water was sufficient. No traces
of mercury were observed in these flasks. All domestic and industrial
waste samples were stored in high density polyethylene, 1-liter screw-
cap bottles with polyethylene lined caps and preserved to give a final
concentration of 0.5% HNC^. Liquid transfers for dilution purposes
were made with Eppendorf pipets of 0.1, 0.25, 0.5, and 1 ml capacity.

1. Spectro Products Mercury Analyzer Model HG-2
2. Perkin-Elmer Model 56 multi-range chart recorder
3. Harmonically smoothed voltage stabilizer
4. Technicon Auto-Analyzer Unit consisting of:
a. Sampler IV
b. Proportioning Pump III
c. Heating bath with heating coil (20 ft. long
and 2.4 mm internal diameter).

5. Gas-Liquid Separator
6. A rotameter to measure the rate of air. flow in the gas-
liquid separator.
7. High speed blender for sample homogenization
The operating principle of the mercury analyzer is based upon
o
balancing the intensity of the mercury line at 2537 A from a hollow
cathode lamp "A" against the intensity of one or more lines from a
reference hollow cathode lamp "B" in the same wavelength region as
observed by a single detector. Lamp "A" is a pulsed mercury hollow
cathode lamp, and lamp "B" is a pulsed iron hollow cathode lamp. The
two lamp sources are pulsed 180° out of phase above a sustaining base
current in a square wave mode. The. instrument is balanced with the
absorption cell swept free of any residual mercury. In the absence
of any interfering substance, any observed absorption is solely due
to mercury.- The net intensity due to mercury absorption is directly
obtained from the output of a phase sensitive, lock-in amplifier. The
instrument is equiped with an automatic gain control to the lock-in
amplifier, so that compensation for the background or extraneous ab-
sorption is accomplished automatically. In addition, a 10X scale
expansion is provided for the analysis of samples containing low con-
centration levels of mercury.
It was found necessary to modify the absorption cell supplied
with the instrument. The main modifications were: 1. To decrease the
internal diameter by a factor of two; 2. To position the inlet and
exit tubes as close as possible to the quartz windows so as to decrease
-------
the dead air space in the vicinity of the window. In order to compensate
for the factor of four decrease in signal strength caused by these modi-
fications, it was necessary to increase the gain (voltage) on the photo-
multiplier tube. The present cell's dimensions are: 22 cm long, 7 mm
internal diameter, and 11 mm external diameter. The cell is constructed
completely from quartz.
The chart recorder is equiped with a variable input voltage,
allowing several scale expansions. The recorder was operated at its
lowest chart speed of 5 mrn/min.
Reagents. All chemicals used are analytical reagent qrade or
better. The water used was doubly deionized. The reagents and their
concentrations are as follows:
]. Concentrated sulfuric acid; obtained from Baker and desig-
nated as "suitable for Hg determination".
2. 10% stannous chloride solution; prepared in a solution
10% in HC1.
'3. 1% potassium permanganate solution; a fresh stock solution
was prepared every three weeks.
4. 2% potassium dichromate solution.
5. 3% hydroxylamine hydrochloride; prepared in a solution
3% in sodium chloride.
6. 4% potassium persulfate; this solution was prepared fresh
weekly.
7. Con. nitric acid.
8, A tank of purified nitrogen.
9. Mercury stock solutions; 1 mg/ml (=1000 mg/1) of either
mercuric chloride or methyl mercuric chloride.
10. Mercury standard solutions. Mercury standard solutions
in the range 0.05 - 6.0 ug/1 were prepared by proper
dilutions of a 100 yg/1 stock solution prepared from
-------
solution 9 above. All standards were prepared in a
solution 0.5% in HN03 and 0.05£ in K2Cr207 as a pre-
servative.
11. Activated charcoal, as an absorber for elemental Hg.
Procedure. The flow diagrams for the mercury manifold are given
in Figures 1 and 2. Figure 1 represents all experiments with K2S208 as
the only oxidizing reagent used for sample digestion. Figure 2 repre-
sents all experiments in which KMn04 or i^C^Oy is used as an oxidizing
agent in addition to K2S20g. In the second system a 3% hydroxylamine-
hydrochloride solution is used as a reducing agent for the excess KMnC^
or i^C^Oy which was not reduced in sample digestion. It should be noted
here that all connections, coils, etc. in the sample train past the pump
tubes are made of borosilicate glass. The heating bath is set at 100±
2°C, and the mercury analyzer is allowed to stabilize for a one hour
warm-up period. The system is then flushed with a 1% HNOs solution and
the absorption cell is flushed with purified nitrogen gas. The rotameter
is set to give a constant gaseous flow rate of 15-25 cm^/min. The inlet
to the segmenting air tube as well as the outlet for the absorotion cell
are connected to a tube filled with activated charcoal which acts as a
mercury absorber. The reagents are then passed through the system in
the-order: a. H2S04, b. SnCl2, c. NH2OH-HCl-NaCl, d. KMn04 or
K2Cr207, e. K2S2Og; while the automatic sampler is kept in the wash
cycle. The wash is made of a 1% HN03 solution. The flow of all reagents
is maintained for a period of 15-30 min. or until a stable baseline is
obtained. In all experiments done using*K2S208 as the sole oxidizing
-------
agent, both the hydroxylamine and permanganate or dichromate reagent
lines are disconnected, and the reagents introduced in the order
^$0)4, SnC^, and K2S2Og. After a stable baseline is obtained, standards
in the range 0.05 - 6.0 yg/1 Hg are placed in a sample tube (prerinsed
with the same solutions), and transferred to the sampler. For all
samples judged to be high in mercury i.e. 0.5 - 6 yg/1, only standards
in that range are used. For low level mercury determination i.e. less
than 0.5 yg/1, standards in the range 0.05 - 0.5 ug/1 are used, and
the mercury analyzer is set at its 10X scale expansion. In addition,
a recorder scale expansion (a factor of 2) is used for runs with mercury
concentrations in the range 0.2 - 3 yg/1. Samples to be analyzed are
then placed in the sampler while the standards are running. Standards
were prepared fresh daily from the stock solution and analyzed by the
system before and after each run in order to provide a calibration curve
and to check for the stability of the standards during the analysis
period. In some experiments the same standards were run over a period
of two to four weeks to check for the effectiveness of the preservatives
used (0.05% HN03 and 0.05% K^C^O;). Both mercuric chloride and methyl
mercuric chloride standards were used to check for the recovery of or-
ganomercury compounds.
All sampling was done using a 20/hour sample cam with 2:1 wash-
sample ratio. For recovery studies, arbitrarily selected samples were
spiked with the equivalent of 0.3 yg/1 Hg for samples with less than
1 yg/1 Hg, and with 2-3 yg/1 Hg for samples containing 1-4 yg/1 Hg.
-------
8
All samples containing high concentrations of participate matter
were first homogen-ized using a Techmar Co. high speed homogenizer model
SOT. In addition, samples were stirred before and during sampling.
After the analyses are completed, all lines with the exception of
the sulfuric acid line are placed in a 1% HN03 solution until all reagents
are completely flushed out. This is followed by placing the sulfuric
acid line in the wash. All the lines are then flushed for 10 min. with
3% N^OH-HCl to remove any build-up of manganese oxides. This is then
followed by flushing the system with 1% HN03 for a period of 20-30 min.
The above flushing includes all coils in and outside the high temperature
bath. For all experiments, using K2S20g or l^C^Oy as oxidizing agents,
the system was flushed with a ]% HN03 solution for 20-30 min.
-------
SYSTEM DEVELOPMENT
During the early stages in the development of the system,
several studies were undertaken to optimize the analysis conditions.
These studies included mechanical, electrical, as well as chemical
modifications.
Modifications in the Mercury Analyzer. It was observed
that the absorption cell provided by the manufacturer was inadequate
for our purposes. The position of the inlet and outlet tubes was
too far from the quartz windows leaving a dead air space. This re-
sulted 'in the retention of mercury in the cell and slowed the response
time. The response time could not be sufficiently improved by varying
the flow rate of the nitrogen carrier gas. In addition, the volume
of the cell was too large, requiring a much longer sampling period.
In the present cell these problems were corrected as described in
the experimental section. As a result of these modifications, we
observed an increase in the sensitivity of the system, a decrease
in the background level, and a decrease in the time required for the
maximum absorption to take place.
Air or Nitrogen flow rate. Table I gives the relationship
between the scale reading on the recorder and the flow rate of air
used for aspiration, for mercury concentrations of 0.5, 1, 2, 3 and
4 yg/1. Inspection of Table I shows that the scale reading increases
with the increase of the flow rate of air up to a maximum. The max-
imum is reached at a flow rate of 20-25 cm3/min. Above 30 cm3/min,
-------
10
however, the scale reading of the recorder decreases. The variations
in the scale reading are more significant at higher mercury levels.
It should be noted here that the results will vary from one system to
another. The flow rates of the other reagents will, of course, change
the molar concentrations of mercury in the solution to be aspirated
and hence, the response of the mercury analyzer.
It should be mentioned here, however, that the total area
under the peak of a given mercury concentration remained virtually
constant up to 30 cm^/min of air. Peak separation, however, decreases
with the decrease in air flow.
Preservation of Samples and Standard^. It has been recognized
for a number of years " that aqueous solutions of mercury compounds
lose their strength on storage. This result was observed for samples

stored in glass as well as polyethylene vessels. Although the mechanism
for the loss of mercury is currently unknown, several interpretations
have been given. The absorption of mercury on the surface of the con-
tainer is perhaps the most common of these interpretations. The amount
of mercury lost from aqueous solutions decreases, however, when the
sample is stored in acid solution. ~ Feldman showed that mercury

standards preserved in a solution 5% HN03 + 0.052 K2Cr207 will maintain
their mercury concentrations over a period of 10 days.
In an attempt to establish the stability of the standard mercury
solutions, as well as that of mercury in environmental samples, several
j
solutions were prepared and analyzed over a one month period. Table II
gives data collected on samples prepared in deionized water, surface
water containing industrial waste, sewage treatment plant (STP) effluent
and STP influent. Three different sets of solutions were prepared for
a given sample type: unpreserved, 0.5% HN03 preserved,and 0,5% HNO-^ -
0.05% KgC^Oy preserved solutions. Both polyethylene and glass bottles
were used for the unpreserved samples. All other samples were prepared
in polyethylene bottles. The mercury content of all samples was first
analyzed. Each sample was then spiked with a known amount of HgCl2,
and the total mercury present was determined within 10 minutes of sample
preparation. The volume of the samples was measured using a graduated
cylinder,and hence a difference of 2-3% between the mercury found at
zero time and the sum (Hg present and Hg added) is not significant.
Table II shows that unpreserved standards (samples prepared in
deionized water) lost 20% of their strength within 10 minutes of prepar-
ation and 60% over a 10 day period. Standards prepared in 0.5% HN03
lost 6% and 30% of their strength over a 10 minutes and a 10 day period
respectively. The use of sulfuric acid instead of nitric acid as a pre-
servative did not significantly alter the results, although sulfuric acid
preserved standards were generally 3-5% higher. This could be attributed
to the presence of trace amounts of Hg in sulfuric acid. Increasing the
-------
12
acid concentration up to 6% resulted in a mercury loss of 20% over a 10
day period. The preservation of standards in a solution containing 0.5"'
HN03 + 0.05% K2Cr2Q7, however, resulted in no significant mercury loss
over a four week period. Similar results were obtained for standards
stored in borosilicate glass, with a slight increase in stability over
polyethylene bottle stored solutions.
Further inspection of table II shows that all environmental
samples studied maintained their mercury content over a one month period
when preserved in either 0.5% HN03 or 0.5% HN03 - 0.052 K2Cr207. Although
unpreserved solutions of the same samples exhibit Kg loss, they do so at
a much slower rate than that for standards prepared in deionized water.
The rate of loss decreased with the increase in particulate matter in
the sample. The stability of these samples, could, thus be attributed
to the preferential adsorption of Hg on the particulate matter. The
stability of samples preserved in 0.5% HN03 - 0.05/3 K2Cr207, however,
was independent of the particulate matter content. The stability of
samples preserved in 0.5% HN03 alone, showed a dependence on the parti-
culate matter. The absence of particulate matter will result in lower
stability. It is thus suggested that all samples should be preserved
in 0.5% HN03 - 0.05% K2Cr20?.
Of particular interest is the comparison of the data for unpre-
served samples over a 24 hour period. Here we observe that deionized
water samples lost 30% of their strength, while environmental samples
lost up to 10% of their strength over the same period. This result
bears very heavily on the method of sampling. It is suggested that
-------
13
grab samples are collected followed by immediate preservation with 0.53
HN03 - 0.05% i^C^Oy solution. This is preferred over, say, a 24 hour
non-acidified composit sampling method. Any loss of mercury due to
surface adsorption in a grab sampling method should be recovered upon
the addition of the preservative. Thus it was observed that if a mix-
ture of 0.5% HNO^ - 0.05% K£Cr207 was added to a neutral aqueous solution
of HgCl2 (2 yg/1) which had been left standing for 24 hours, all the Hg
was recovered within 20 minutes. In addition, a comparison (table II)
of the Hg concentration in the samples prior to the addition of the
spike (HgCl2), shows that the nitric-dichromate values are significantly
higher than nitric alone, which in turn are higher than the unpreserved
samples. The difference is attributable to the redissolution of Hg
adsorbed on the surface of the flask, since the- reagents did not show any
measurable Hg contamination.
Comparison of Organic and Inorganic Standards. Methyl mercuric
chloride and mercuric chloride produced the same standard graphs over
the range 0.05 - 6.0 yg/1 Hg. All data in the range 0.05 - 0.5 yg/1
were run on the 10X scale of the mercury monitor and IX scale expansion
for the chart recorder. All data in the range 0.5 - 6.0 yg/1 Hg were
run on the IX scale of the mercury monitor and at the 2X scale expansion
of the chart recorder. Two types of standard graphs were attempted.
The first is a plot of the percent absorption due to mercury versus the
mercury concentration; the second is the absorbance (optical density)
versus the mercury concentration. Both graphs gave very good straight
lines, and the results (for real samples) calculated from both graphs
are indistinguishable. At concentrations of mercury of 10 yg/1 or above,
however, the % absorption graphs are generally non-linear.

RESULTS AND DISCUSSIONS
Figures III and IV give typical chart recordings of measurements
made on standard solutions. Recorder plots of 0.5, 1.0, 2.0, 3.0 and
4.0 yg/1 Hg (Fig. Ill) were obtained on the IX scale of the mercury
monitor and scale expansion of 2X on the chart recorder. Attempts to
vary the damping of the instrument (without significantly affecting
the response of the monitor) were unsuccessful in decreasing the base-
line noise. The present chart recordings are done at a damping control
of 10 sec. Figure IV gives the plots of mercury concentrations of
0.05, 0.1, 0.2, 0.3, and 0.4 yg/1, all done on the 10X scale of the
mercury monitor, and a IX scale of the chart recorder. Here again
attempts to decrease the noise level of the baseline beyond what is
given were unsuccessful. The detection limit of the method (defined
as the concentration that gives a signal that is twice the level of
the baseline noise) on the range 0-0.6 yg/1 is 0,05 yg/1. The de-
tection limit could be decreased beyond the 0.05 yg/1 level to perhaps
0.02 yg/1 if an integrator is coupled with the chart recorder, which
would average the baseline noise and hence increase the sensitivity
of the procedure. Inspection of Figures III and IV shows that the
wash sample ratio of 2:1 is sufficient for our system with a complete
return to the baseline between samples. The shape of the peaks is
quite characteristic at all levels of mercury, and with a one minute
sampling time, a steady state concentration of mercury is reached in
-------
15
the absorption cell. This was established by sampling for an extended
period of time and observing that the percent absorption attained is
the same. The reproducibility of the results (precision of the method)
was established by replicate analyses of the same sample. Table III
gives the standard deviations and the coefficients of variations (per-
cent relative standard deviation) at various levels of mercury. Data
for the manual method are also given as a reference. These data were
obtained from standards run during the same day as well as over an
extended time period. Reproducibility data for real samoles were
generally within the standard deviation of the standards (for samples
with small amounts of particulate matter when run on the same day).
Reproducibility data for samples run on different days, however, were
within 2-3 standard deviations of the standards. This could be attri-
buted to sample deterioration, preferential adsorption of mercury on
particulate matter, or day to day changes in the elasticity of pump
tubing. Samples with considerable amounts of particulate matter were
sampled representatively by homogenization using a high speed blender.
The reproducibility of these samples was within 2-3 standard deviations
of the standards.
Since mercury in water can exist as organic mercury, it was
necessary to establish the completeness of the digestion procedure,
as well as the effectiveness of the various chemicals involved in the
break-down of organic mercury compounds to ionic mercury. This is
necessary since SnC^ will not reduce organic mercury under the exper-
imental condition given. It should be mentioned here that it was not
-------
16
necessary to use potassium permanganate nor potassium persulfate for
samples containing inorganic mercury only. In addition, the temperature
of the reaction need not be above room temperature.
Standards containing methyl mercuric chloride, however, required
high temperature (100°C) and the presence of persulfate. Potassium
permanganate alone gave less than 302 recovery of the mercury present.
Potassium persulfate alone was sufficient to recover all the mercury
present. Variation of the concentration of ^2^8 between °-5 " ^ dl'd
not alter the results obtained for methyl mercuric chloride. Since
the variation of the flow rates of reagents and/or the total volume of
solution in the reduction step affects the final value obtained for the
percent absorption on the chart recorder at a given concentration, all
data were obtained relative to mercuric chloride standards. Table IV
gives recovery data for methyl mercuric chloride using various reagent
combinations. The methyl mercuric chloride standard solution used
(obtained from Alpha Inorganic) was found to contain 1% HgC^. This
was established by treating a 100 yg/1 sample of CF^HgCl with SnCl-
and observing an absorbance level 1% of the expected absorbance.
The variation of the concentrations of the various reagents,
however, affected the data obtained for real samples. It was thus
observed that there is a direct correlation between the chemical
oxygen demand (COD) and the amount of persulfate and/or permanganate
required to completely oxidize all organic mercury present. The COO
19
of a sample is defined as "the quantity of oxygen required to oxidize

organic and inorganic matter in a waste sample." This definition is
based on acidic dichromate oxidation at the reflux temperature of a
2
50% H2S04 solution with a Ag2S04 catalyst. Since both S20g and Mn04
are excellent oxidizing agents, all organic matter oxidized by dichromate
should also be oxidized by persulfate or permanganate and hence the
correlation between the COD of the sample and the concentration of
these reagents. It was thus observed that the suggested concentrations
12
of 0.5% KMn04 and 0.52 K2$20g by Bennett et. al. , are insufficient
for most samples treated in this laboratory. In the present system,
a 4% K2S2Og (Fig. I) is sufficient to treat samples with a COD of up
to 700 mg/1. Attempts to increase the concentrations of these reagents
were judged inadequate for our purposes, because an increase in KMnO^
concentration would require a large increase in the hydroxylamine
needed to reduce excess MnO^~. Increasing the persulfate concentration
by the use of up to 15% (iNH^)2S2Og solutions, resulted in the formation
of high levels of ozone after the digestion step, and hence, a need
for a high concentration of SnCl2. Since over 90% of water and waste-
water samples that come to this laboratory have a COD value of less
than 500 mg/1, it was decided that a 1% KMnO^ and/or 4% <<2S2Og solutions
are sufficient. Samples with much higher COD levels (above 700 mq/1)
should therefore be diluted. It was also observed that spiked samples
with high COD levels gave a mercury concentration lower than the spike,
Here methyl mercuric chloride should be used as the spike.
Table V gives a comparison between the automated method and
the manual method for river, lake, sewage, and industrial samples. Data
-------
were included for experiments performed using persulfate alone, persulfate-
dichromate, and persulfate-permanganate as digestion solutions. Table VI
gives recovery data of spiked real samples using the above solutions.
Inspection of the two tables shows that there is no significant difference
in the values obtained for the same sample by the various methods studied,
and that potassium persulfate is sufficient as a digestion reagent. Per-
haps the main purpose for permanganate in these experiments is its five
electron oxidation property as compared to the two electron step for per-
?- ?-
sulfate. The electrode potential for the S20g /S04 couple is 2.03 V
while for the MnO^/Mn couple is 1.60, and here it appears that apart
from kinetic effects, the persulfate on a thermodynamic basis is a better
oxidizing agent. The fact that the use of MnO^" alone results in a maximum
of 30% recovery of CHJ-lgCl eliminates the value of MnO*~ for the analysis
of organic mercury compounds.
20
It was eluded to by Kopp, et al. , that the use of Mn04~ might

be required for the oxidation of some interferences such as F^S. Since
persulfate is a strong oxidizing agent, it appears that the permanganate
will not be required for this purpose. In addition, it was observed
that sulfide concentrations as high as 20 mg/1 (as Na^S) do not interfere
with the recovery of inorganic mercury added to distilled water. This
result was obtained in experiments using persulfate, persulfate-permanganat
-------
19
and persulfate-dichromate combinations as digestion solutions. At higher
sulfide ion concentrations, however, negative interferences were observed
in experiments using persulfate alone. In experiments using persulfate-
permanganate or persulfate-dichromate, a positive interference was ob-
served. Other common ions encountered, such as chloride, did not inter-
fere in concentrations of up to 5000 mg CT/1 in all three digestion
solutions. Residual chlorine results in a positive interference, when
the K2$208 manifold is used. For these samples, a solution 3% in
N^OH-HCl-NaCl is to be added to the sample stream immediately after
the digestion step at the rate of 0.3 ml/min. CuS04 did not interfere
in concentrations of up to 1 g/1. Ethyl alcohol, methyl alcohol, glycerol ,
chloroform, and carbon tetrachloride did not interfere when added in
concentrations as high as 0.5*. Major interferences were observed,
however, from benzene and toluene. A maximum tolerance of 500yq/l was
obtained for these compounds. The above illustrates that the use of
KZ^OS as the sole oxidizing reagent in the digestion step is sufficient.
The elimination of KMn04 results in a stable base line and removes inter-
ferences caused by the precipitation of manganese oxides in the tubes.
In addition, high backgrounds generally observed in Hg determinations
using KMnO^ are eliminated.
The present method is suitable for the separate determination
of inorganic and organic mercury. For this purpose, the inorganic mercury
is determined by the removal of all reagents except for the SnCl£ solution
**+
used for the reduction of Hgc . The temperature of the system is maintaine
at room temperature, and the inorganic mercury concentration is read off
-------
20
a calibration curve made of known concentrations of HgCl2 run under
the same conditions. Inorganic mercury as determined by this method
is defined as all mercury compounds that are reduced to elemental
mercury by SnCl2 without predigestion of the sample. The total mercury
in the system is then determined, using the normal digestion and re-
duction steps and read off a calibration curve done under the same
conditions. The difference between total and inorganic mercury is
the amount of organic mercury in the samples. Table VII gives the
date for inorganic and organic mercury content of real as well as
artificial mixtures. No attempts were made to analyze for organic
mercury independently.

MICRO METHODS FOR THE DETERMINATION OF
NON-FILTRABLE AND FILTRABLE RESIDUES
Mark J. Carter, Madeliene T. Huston and Oliver J. Logsdon II
April 18, 1975
-------
ABSTRACT
Rapid, micro methods for the determination of non-filtrable
and filtrable residues are reported. Non-filtrable residue analysis
of wastewaters is accomplished using up to 10 ml of sample for a de-
tection limit of 1 mg/1. Using the suggested sample sizes, all filtra-
tion work is completed within ten minutes. Filtrable residues are
determined on a 100 ul sample which is dried at 180°C for one-half hour.
Thirty samples can be analyzed for both residue parameters in less
than three hours. Both micro methods were shown to produce results
comparable to the standard methods with better precision.
-1-
-------
The determination of non-filtrable and filtrable residues
are among the oldest determinations in water analysis. While old,
residue analyses remain important in assessing the quality of waste ,
surface and potable waters. At least one residue parameter is
included in a list of significant parameters for assessing the quality
of effluents from each of twenty-two major industrial groups iden-
i
tified in a recent EPA report.
The most widely used procedures for determining filtrable
residue are given in "Standard Methods". Selection of a drying
3 tj, 5
temperature of 103-105°C ' or 180°C is left to the discretion
of the analyst. Howard evaluated both drying temperatures and found
that the value for filtrable residue, based on drying at 180°C,
agreed best with the sum of the determined constituents for most
natural waters.0 The EPA has adopted the 180°C drying procedure
7 g
for routine use. ' However, a large sample volume and hence a
long drying time are required to achieve good precision with the
standard filtrable residue procedure. Another requirement to obtain
good precision is the careful desiccation of the weighing dishes
after sample evaporation.
Allen and Bacon reported a micro method for determining
filtrable residues which requires a substantially smaller sample volume
Q
and shorter drying time than the standard method.' They eliminated
the problem of sample desiccation by placing the weighing chamber
-7-
-------
of a Cahn micro balance in a drying oven at 105°C. Unfortunately,
this drying technique is not applicable to the 180°C filtrable re-
sidue procedure because the maximum operating temperature of the weighing
chamber is 11QOC.
A substantial amount of work has been performed on improving
the standard Gooch crucible-asbestos mat procedure for the deter-
io-it
ruination of non-filtrable residues. Chanin et a!., have iden-
tified the major difficulties with the asbestos mat technique as
being due to variations in asbestos quality, preparation of non-
uniform mats, mat disturbance during handling, and a slow filtration
10
rate. Degen and Nussberger found that the mat must be carefully
washed, before taring and after sample filtration, to avoid erroneous
14
results.
10 11
Chanin et a!., and Nusbaum simultaneously reported similar
non-filtrable residue methods using glass fiber filters which greatly
1 2
reduced problems with mat preparation. Engelbrecht and McKinney
used the membrane filter for non-filtrable residue analysis but re-
ported a slow filtration rate for some samples. Harada et al., also
noted this problem using glass fiber filters and reported a procedure
utilizing a combination filter mat consisting of both coarse asbestos
and a glass fiber disk.
Smith and Greenberg compared and evaluated five of the non-
filtrable residue methods in common use, including the standard
15
procedure. Three glass fiber filtration techniques were compared
to an asbestos mat and a membrane filter method. They found no
-3-
-------
statistically significant bias or different coefficients of variation
between the five methods. However, none of the procedures studied
combines speedy filtration with ease of filter media preparation.
The problem of a slow filtration rate becomes serious when a large
volume of sample must be filtered for filtrable residue analysis.
A fast, efficient and accurate method for determining non-filtrable
residues that combines a minimum of filter handling with rapid
filtration is reported in this paper. A rapid method for deter-
mining filtrable residues using only 100 yl of sample is also reported.

METHODS
Apparatus. AH weighings were performed on a Mettler ME22 electronic
microbalance equipped with BE22 control and BA25 digital display units
and a Nuclear Products Co. 500 uC Po 210 ionizing source. All of the
filters evaluated are listed in Table I. The Nuclepore 25 mm diameter
0.4 ym standard polycarbonate membrane filter was chosen for routine
use. Sample filtration was performed with a Mi Hi pore thirty-place
membrane sampling manifold using 15 x 125 mm culture tubes to receive
the filtrate. Liquid transfers for non-filtrable residue analysis
were performed with a 1-5 ml or 5-10 ml Oxford Laboratories Macro-Set
pipet with disposable tips. A 100 ul Eppendorf pipet with disposable
tips was used for liquid transfers for filtrable residue determinations.
Cahn 12 mm diameter aluminum pans were used as evaporating dishes for
filtrable residue analysis. Coors 03 12-place spot plates were used
to hold the aluminum pans. Two control standards for filtrable residue
analysis were prepared with NaCl to be 400 and 500 mg/1. Non-uniform
samples were homogenized with a Tekmar model SOT.
Non-Filtrable Residue. Weigh the Nuclepore filters to the nearest
microgram directly out of the box. Pass the filters about 1 inch over
the Po 210 ionizing source in the weighing chamber to reduce the
electrostatic charge. Place the weighed filters in numbered 60 mm
aluminum weighing dishes until they are to be used. Wash and dry the
sample wells and filter supports of the sampling manifold. Load the
filtrate receiving rack with 15 x 125 mm culture tubes and assemble the
manifold as per Millipore Co. instructions. Place the filters on the
-5-
-------
manifold by first dipping each filter in distilled water so they
adhere to the support. Homogenize all non-uniform samples. Choose
a volume of a surface or wastewater to filter so that no more than
2.0 mg of residue will remain. Discard any sample which does not
filter in ten minutes and re-filter a smaller sample volume. Gener-
ally, volumes filtered are 10 ml for a surface water or wastewater
effluent (up to a concentration of 200 mg/1), and 1 ml for grossly
polluted samples (up to a concentration of 2000 mg/1). In addition,
analyze one sample in duplicate and the two filtrable residue control
standards (also used as blank filters) per set of samples. When
filtration is complete, disassemble the sampling manifold, remove
the filtrate receiving rack and reassemble the manifold. Wash each
filter with two 5 ml portions of distilled water. Remove the filters
from the sampling manifold, return them to the numbered aluminum
weighing dishes and place in an oven at 103-105°C for 1/2 hr. Remove
from the oven at one time only the number of filters that can be
weighed before the aluminum pans cool. The final non-filtrable residue
values are corrected for the change in blank filter weights. The cause
for a blank of more than 0.01 mg should be investigated before reporting
the results.
Filtrable Residue. -Weigh the Cahn 12 mm diameter aluminum pans to
the nearest microgram and place on a numbered Coors spot plate. Trans-
fer one hundred ul of each sample to the residue dishes with an
Eppendorf pi pet. Analyze the A and B control standards just like the
real samples. Carry two blank pans through the drying and weighing
process. Correct final filtrable residue values for the change in
blank pan weights. The cause for a blank of more than 0.003 mg should
-6-
-------
be investigated before reporting the results.
RESULTS AND DISCUSSION
Non-Filtrable Residue Method Development. The primary considerations
in developing a new non-filtrable residue method were the ease of
filter media handling and a rapid filtration rate. Harada et al.,
solved the filtration rate problem by using a media that was difficult
to prepare. Most investigators have found glass fiber and membrane
filters easy to use but of limited loading capacity, especially the
latter ones. One proposed solution to this problem is to use larae
11
diameter filters.
The authors decided the best solution to the media handling and fil-
tration problem was to use glass fiber or membrane filters with a
small enough water sample volume that would pass through the media
quickly. Initial experiments with grossly polluted wastewaters, using
25 mm glass and membrane filters, showed that no more than 10 and 5 ml,
respectively, could be filtered in less than 10 minutes. For monitoring
stream and wastewaters the method must be capable of measuring down to
5 mg/1. This means that residues of O.OStng (using 10 ml samples) must
be determined accurately. Since micro balances measuring to the nearest
0.0001 mg are available, the real limitation of the method is the stabil-
ity of the filters.
-7-
-------
Filter Stability. The two major causes of filter instability are
weight loss due to wash-out or "media migration" during filtering
and the volatilization of filter material during the drying process.
The bias introduced by "media migration" during sample filtration
2. 7
can be eliminated by pre-washing the filter.' However, this in-
volves an extra step in the analytical procedure. The thermal
instability problem exists mainly with the membrane-type filters and
13
has only been resolved by drying in a desiccator. However, this
procedure is more time consuming and could result in a positive bias
when compared to the 105°C drying method.
When filtering small volumes, and hence weighing small amounts of
residue, an undetected weight loss from a filter can significantly
bias the results. Ten filters were evaluated for their stability
upon filtering 10 ml of water and drying at 105°C for 1/2 hour. The
results in Table I show the weight losses for three binderless glass
fiber filters (Reeve-Angel 934 AH, Gelman type E and Millipore AP4n)
two glass fiber filters with an acrylic resin binder (Millinore APIS
and AP20) and five different membrane-type filters (Nuclepore,
Millipore MF, Gelman TCM, Millipore HATF, Gelman AN1200).

-------
The mean weight loss and the standard deviation of weight loss based
on ten replicates were very similar for the three binder!ess glass
filters. The weight loss, if unaccounted for, would bias the results
by an average of 11 ± 5 mg/1 at the 95% confidence level. While the
mean weight loss for the bindered and unhindered filters was similar
the standard deviation of the weight loss for the former has half
that for the latter filters. These experimental results confirmed
the visual observation that the bindered filters were structurally
sounder and sloughed off less filter material during handling. Except
for the Nuclepore filter, the membrane filters exhibited either a
larger mean or standard deviation of weight loss than the glass filters.
The Nuclepore filters showed the smallest mean and standard deviation
of weight loss of all the filters tested.
Table II shows weight loss results from filters which were pre-washed
three times with 10 ml of de-ionized distilled water and dried before
filtering the test 10 ml aliquot of water. Prewashing the glass fiber
filters substantially reduced the mean and standard deviation of weight
loss. Prewashing the cellulose membrane filters substantially reduced
their weight loss during filtration.
Further experiments were performed to determine the cause of weight
loss during the filtration-drying process. Samples of the filters listed
in Table I were dried at 105°C for 1/2 hour. The Nuclepore and ail of

glass fiber filters were stable to 0.002 mg. The other membrane filters
showed substantial weight losses which were less than the total weight
losses from the filtering and drying process. Therefore, the glass
filters lose weight only during the filtering process whereas the cellu-
lose membrane filters lose weight during both the filtering and drying
process. This conclusion was verified by experiments which showed that
the cellulose membrane filters continued to lose weight during the drying
process even after they were thoroughly washed.
As a results of the above experiments the Nuclepore and the Mi Hi pore
AP20 hindered glass filter were chosen to evaluate the micro technique.
A drying time of 30 minutes was shown to be adequate for both filter
types by re-drying a set of particulate laden filters for 24 hours
without any addition weight loss. Due to the low heat capacity of the
filters, they could be weighed directly from the oven without cooling
in a desiccator.
The relative humidity during the course of this work was always below
30% and although a desiccator was not used no filter weight gain from
hygroscopic effects was observed. Tierney and Conner showed that at
100% relative humidity clean glass fiber filters will gain about 5% in
1 9
weight. They also showed weight gains up to 80% for particulate-
laden glass filters at 100% relative humidity. However, at relative
humidities below 55% the weight gain of three different samples was
less than 1%. A weight gain of only 0.24% has been reported for
20
Nuclepore filters immersed in water for 24 hours. This property,
combined with the low tare weight of the
-12-
-------
filter were the deciding factors in choosing the Nuclepore filter
for routine use. If cost is a serious consideration, then pre-washed
glass fiber filters can also be substituted. Whichever filter is
used, it is desirable to maintain the relative humidity below 50%
during the weighing process. It was also determined to be necessary
to keep a Po 210 alpha ionizing source in the balance weighing
chamber to eliminate an electrostatic charge build-up on the Nuclepore fil
Non-filtrable Residue Methods Comparison. The data in Table III compare
results using the micro method and the standard method. ' The ratio
of the micro (using the Nuclepore filter) to the standard method results
is 1.04 ± 0.37 which is not significantly different from one (T-test,
a = 0.05). Smith and Greenberg also reported no statistically significant
bais in results determined using the standard method with membrane and
glass filters. However, their results from the membrane filters were
slightly greater than the glass filters.
For the micro method, the ratio of results using Nuclepore and Mi Hi pore
AP20 filters is 1.07 ± 0.11, which is not significantly different from
one (T-test a = 0.05). However, the results from the Nuclepore filters
are slightly greater than from the glass filters. Cranston and Buckley
reported that both Nuclepore and glass filters quantitatively retained
2 urn beads, whereas the retention of 1 urn beads was 98 and 26% respec-
1 5
tively. Therefore, filtering the same volume of a wastewatar through
Nuclepore and glass filters of the same diameter should produce higher
results for the former filter. The magnitude of the difference would
depend on the particle size distribution of the samples.

-------
A paper industry report presented data to show that using the standard
method, the larger the volume filtered, the higher the determined
21
non-filtrable residue concentration. Obviously, the larger the
volume of water filtered, the greater the amount of residue collected
and the more difficult it would be to thoroughly wash the filter.
Cranston and Buckley found that a rinse of 25 ml of deionized water
was not sufficient to remove trapped inorganic salts from a 25 mm
16
glass fiber filter after filtering sea water. In addition, if
enough residue was collected to act as a pre-filter, higher results
would be determined for larger volumes filtered.
Several samples were analyzed in triplicate by the micro method using
three different sample volumes. The results in Table IV show that,
using the micro technique, there is no universal increase in non-
filtrable residue results with increasing sample volume. The largest
volume filtered corresponds to no more than 3 mg of residue on a 25 mm
filter with a maximum filtration time of 10 minutes. No problem was
encountered washing the filters. The results reported in the paper
industry report correspond to a 10 mg residue on a 21 mm filter with
filtration times over 2 hours. Obviously, the paper industry filters
could not be washed properly. In order to assure proper washing of
the residue, sample volumes are chosen so that the maximum filtration
time is 10 minutes. This corresponds to a maximum of 2-3 mg residue
depending on the clogging characteristics of the sample. Any filter
that becomes clogged must be discarded to avoid erroneous results such
as those reported in the paper industry report.
-15-
-------
Initial work to define the precision of the method revealed poor
duplication of results for samples with non-uniform particulate
matter. Thereafter, all samples with non-uniform particulate matter
were homogenized with a Tekmar SDT blender. In order to show that
the process of homogenization does not alter the non-filtrable re-
sidue concentration, a raw sewage sample was analyzed ten times
before and after blending. The results (blended, 279.0 ± 4.8 mg/1;
unblended, 280.0 ±8.0 mg/1) show that the mean results are not
affected but the precision is improved by blending the samples.
The precision of the micro method on the variety of sample types
studied is 3 mg/1 below 50 mg/1 non-filtrable residue and 9 mg/1
above 50 mg/1 at the 95% confidence level. The average coefficient
of variation for all samples is 4.0%. Smith and Greenberg reported
a coefficient of variation of 4.2% using the standard method.
The absolute detection limit of the method is 0.01 mg (37}. This
corresponds to 1 mg/1 for a 10 ml sample volume.
Filtrable Residue Method Development. The method of Allen and Bacon
was evaluated for use in combination with the micro non-filtrable
9
residue method described previously. Their method used 50 yl of
sample dried at 105°C for 15 minutes and the residue was weighed to
0.0001 mg with results reported to the nearest 1 mg/1. Initial ex-
periments showed that the extra significant figure gained by weighing

to 0.0001 mg was at the expense of several minutes extra weighing
time per sample. Therefore, a 100 yl sample size was chosen, the
residue weighed to 0.001 mg and the results reported to the nearest
10 mg/1. With this sample size, a ten-fold advantage of sample
size to evaporating dish weight exists for the micro over the standard
method.
Howard showed that the figure for total dissolved solids, based
on the weight of residue after drying at 180°C, is close to the
sum of the determined constitutents for most natural waters.6
Therefore, the drying and weighing procedure of Allen and Bacon
was modified to accommodate a 180°C drying procedure. Advantage
was taken of the very large difference in heat capacities of the
aluminum pans and the supporting porcelain spot plate to simplify
the weighing process. After drying for 30 minutes (found to be
sufficient), the spot plates are removed from the oven. As each
aluminum pan is weighed, the remaining ones are kept hot by the
spot plate for up to ten minutes. This technique eliminates the
need for a desiccator.
Comparison of Filtrable Residue Methods. The micro and standard
filtrable residue methods were compared on a variety of samole
types (Table V). The mean ratio of micro to standard method results,
0.99 ±0.18 at the 95f« confidence level, is not significantly
different from one (T-tast* <* = 0.05).

The precision of the micro method was determined from the paired results
in Table V to be 26 mg/1, at the 95% confidence level. At a mean result
of 705 mg/1, this corresponds to a coefficient of variation of 2%.
"Standard Methods" quotes a coefficient of variation of 5% for the macro
2
method. The absolute detection limit, based on three times the standard
deviation of thirty-two blank values, is 0.0021 mg. This corresponds
to a detection limit of 21 mg/1 using a 100 yl sample volume.
There is no method of assessing the accuracy of filtrable residue

determinations on real samples. Howard and Sokoloff showed that the
loss of some chloride and nitrate are unavoidable in the determination
of filtrable residues. However, the A and B control standards were
used to evaluate day-to-day bias in results. For ten determinations
on different days the values of the A and B standards were 506± 19 and
411 ±13 mg/1, respectively. Specific conductance values were also used to
assess the consistency of filtrable residue measurements. The ratio
of residue to conductivity results in Table V is 0.62 ± 0.08 at the
95% confidence level. This ratio corresponds very closely to that
o o
reported by Rainwater and Thatcher, for comparatively dilute solutions.
For solutions with dissolved salt concentrations exceeding 2000 to
3000 mg/1 or with substantial concentrations of dissolved silica and
organic matter, the ratio may be much higher. For waters high in
acidity or alkalinity the ratio can be much lower than 0.62. The
cause of a filtrable residue to conductivity ratio outside of n.62 ± 0.1
should be investigated before any results are reported.
