INTRODUCTION
In response to public concern resulting from publicity about alleged toxic
organic compounds 1n the New Orleans, Louisiana and other municipal drinking
water supplies, Region V States asked for assistance 1n obtaining current data
concerning certain drinking water supplies 1n 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,
polychlorlnated blphenyl mixtures, certain phthalate esters, metals and other
Inorganic parameters 1n drinking waters. Another Interest was to establish
baseline concentrations for those organic compounds of health concern or thought
to result from chlorlnatlon, and therefore to be widely distributed 1n our water
supplies. These compounds Include carbon tetrachlorlde (CC1J, chloroform (CHC13),
bromodlchloromethane (BrCHClp), dlbromochloromethane (B^CHCl), bromoform (Br^CH),
l,2-d1chloroethane (C1-CH2-CH2-C1), dichloromethane (CH2C12), aldrln, dieldrln
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 1n 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 1n 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 otner fixed caoitol depreciations, trans-
portation, etc., remain constant, the most efficient study includes a maximum
number of parameter analyses per samoTe.
-------
It should be emphasized that this study occurred Curing winter months
when waters were cold, surface streams v-are generally at higher than normal
flows and contained considerable suspended solid materia s, agricultural and
gardening activities were at a minimum as were certain industrial activities.
Therefore, concentrations could vary substantially from values reported in this
iwnuscript for samples collected at different times of tie year.
1,2
Based on the data presented 1n Table I, It is cleir that chloroform,
bromodichloromethane, dibromochloromethane and bromoform are consistently higher
1n treated drinking water than in raw waters at most cities in the Region. The
loean concentrations however are quite low.
Table II is a listing of the analytical results f*om which the summary
data 1n Table I were calculated. All concentrations are in micrograms per
liter (ug/1). It is the practice of the Central Regional Laboratory to report
detection limits based on each day's quality assurance d»ta. Therefore, dif-
ferent detection limits are given for some parameters in Table II and other
places 1n this report.
Conclusions that may be reached from an examinati )n 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 chlorofonu, 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 brxnofonn in the
finished water. It appears they result from :hlorination of precursors
in'the raw water. Since there is no pattern to their occurrence,

*excluded from calculation of average and standard deviation. If all data
In Table II are used, both ratio percentages and the scatter increase as
the measurements approach the detection limit
-------
tt do«$ not appear that carbon tetracMorlde, methylene chloride or
1,2-dlchloroethane 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 Til of BrCHCl2 to CHC13 range from 1.2X to 17%.
The range for the BrCHC^/BrgCHCl ratios 1s 0 to 19*. A careful examina-
tion of these ratios suggests that the concentration of BrCHCl2 will be
approdmately 13S that of CHCl^ and the concentration of B^CHCl will be
about 6X 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 1n the chlorine used to purify the raw waters, we
conclude that bromlnatlon is much faster than chlorination and that the
halogen 1s 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 1s 'operative that differs from
that of most cities studied. At first we suspected an industrial
discharge but that conclusion 1s inconsistent with a zero chloroform
concentration for the raw water. Therefore, these supplies Ttay 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
-------
to suggest a .method of rejpoyal. It 1s suggested that check samples
6e collected to fertfy results that truly represent these water supplies.
The concentrations of bromlnated compounds are Mch relative to the
concentrations of chlorinated compounds for some cities. If this
pattern 1s repeated 1n check samples, and should i:he bromlnated 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 1s 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 us'ng carbon have chosen
to do so to reduce taste and odor problems and that the carbon 1s much
wore effective 1n removing those compounds causing the water to have
a taste and odor than 1t 1s In removing the halogonated methanes or
other organic compounds that react to form chloroform.
Table IV summarizes water supply systems Information. Data 1s reported as
It was obtained on field sheets at the time of sample collection. It can be noted
from this table that 1n addition to the characteristics of t!ie 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 :ime must be considered
to be the entire elapsed time from chlorine application until sample analysis
0-5 days). Recent experiments with aliquots of southern Lace Michigan water that
were-treated with 2 r.g/1 of chlorine have shown chloroform production to be cut in
half when the allquots were again treated 1n one hour to remove all remaining
chlorine. Chlorine was allowed to react a number of days in the aliquots where
1t 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 chlcrofsr-i, bromodichl3rorr,ethane,

-------
d1bjrojDoch.lorojDettiane, and total dhJorlne dosage 1n rlyer water systems. Since
the F value at tRe 0,01 probability point ts 7, the null hypothesis of no rela-
tionship Is rejected and 1t 1s 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 1n this study with particular attention to the source
of raw water used 1n treatment.

3. Pesticides. PCB's and Phthalates
Table V 1s 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 1n the survey. All analytical
results are Included 1n the appendix and from these we conclude that:
a. A large majority of the samples do not contain these types of compounds
1n concentration! that can be measured with the procedures used for
this study.
b. For this class of compounds, the most commonly found are dlethylhexyl-
phthalate, dleldrfn. DOT, treflan, aldHn and hexochlorobenzene. The
concentrations of all pesticide type compounds Identified to date
are low. The highest concentrations found were 63 nanograms per
liter (ng/1) for DOT, 11 ng/1 for dieldrln. 17 ug/1 for dlethyl-
hexlphthalate and 50 ng/1 for treflan. All positive results are
given In Table V.
c. Concentrations of PCB's in tnose 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 *n acidic, basic and
neutral fractions giving a total of nine concentrates per *

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. He have not yet
attempted to analyze the extracts for any low boiling compounds except for the
bis-2-chloroisopropyl and b1s-2-chloroethyl ethers. Neither of these compounds
gave a gas chromatographlc 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 Pallutant Discharge
Elimination System program and should reduce concern for E^ansville water.
5. Inorganic Parameters
All samples were analyzed for the following fourteen metals: silver,
arsenic, calcium, cadmium, chromium, copper, iron, potassijm, 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 severa"! deeo wells
as sources. The water from Wildcat Creek does not contain 3 measurable arcun:
of arsenic but watar from two of the 15 ieso wells ccntained up to 2CCO jg/1.
This is aooarently a very localized proc'em af'ect^ng cnly * -?w ^slls. .^f
treatment and slerc'ng the Kokcrrc *ater /.arks has bee" »bla to ^.a;-ta-r
-------
safe concentrations of arsenic 1n 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
1n use.
The arithmetic mean values for all finished water parameter concentrations
are less than drinking water standards with the exception of phenolics (Table VI i
VII). Since the detection limit of the analytical method used to measure phenol
concentrations 1s 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 1s 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
1s log normal rather than gaussian. This point 1s illustrated in Figure 1.
It can be concluded from the data in Table IX that a high chemical oxygen
demand (COO) 1n the raw water is necessary for a high chloroforn concentration
to result 1n 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 we chloroform
precursor reduces potassium dichromate and that those supplies having a lew COD
need not be tested for chloroform.

Numberous drinking water plants add chemicals other than chlorine to the
water during the treatment process. Two commonly used chemicals are ammonia
and polyphosphate. Fluoride is also added to many supplies.
Twenty-one (21) supplies added arrmonia 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 arrcnonia - N in finished versus raw
water 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 polyphospnate. Twelve (12) of these supplies

overall average change 1n phosphorus fron ra* to ^livshed water was negative
0.01 mg/1. Howeve^, these 13 supplies averaged an increase of 0.168 mg/1.

Most supplies add fluoride. This 1s evident from the median fluoride
concentration of 1.0 mg/1. However, 9 supplies apparently do not add fluoride.
Nine (9) supplies had pH values between 9.0 and 10.1. Of these supplies,
six (6) also had CHC13 concentrations greater than 50 ug/1. No additional rela-
tionships were found.
Suspended solids removal was 90 percent based on the mean raw and finished
water values. The highest suspended solids value for a finished water was 42 mg/1,
the second high was 13 mg/1, and all other values were 8 mg/1 or less. No positive
correlation exists between suspended solids and the presence of halogenated organic
compounds. However, COO removal averaged only 50 percent indicating that signi-
ficant amounts of organic materials remained In the filtered water. This sug-
gests that the turbidity standard (suspended solids is the cause of turbidity)
may not be sufficient to protect water supplies from halogenated organic compounds.
6. Economic Considerations
Table XI gives estimates of resources expended tc complete this survey.
All dollar estimates are based on the assumption that total expenses, including
all overhead, costs $40,000 per position and a year contains 260 working days.
III. SIGNIFICANCE
It 1s not surprising that trace amounts of various organic chemicals can
be detected in drinking water. With the sensitivity available in the gas
chromatograph/mass spectrometer-computer equipment it is probable that many
such compounds can be found in almost any facet of our environment that one
chooses to look. Absolute purity 1s only a theoretical term and is not attain-
able in drinking water.
Concentrations that are above a normal background and that do pose a
significant health risk should of course be reduced. There are currently not
enough data to fully understand either the normal background level or the health
significance of the organic compounds included in this study. However, with

-------
perhaps the' exception of chloroform, concentrations of or^anics analyzed in
these drinking waters should not be considered atypical. It 1s not likely that
they will be found to present a significant risk to health. Exposures to these
same compounds from ambient levels 1n other aspects of our environment (smoke,
air, food, medicines, etc.) can be expected to be much greater than that from
drinking water.
Chloroform, 1t appears, 1s affected by chlorine application. Concentra-
tions of chloroform 1n water supplies with a high chlor1n»» 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 1s no evidence that chloroform causes tumors In workers,
and the allowed occupational exposure to chloroform in a I'- 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 carcinogenesls 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 career incidence
rate. A more reasonable assumption, based upon c-.rrent water
quality data which show much lower levels than the worst case in
the majority of U. S. drinking water supplies, wot Id place the
risk of hepatic cancer much lower and possibly nil. Further,
it is emphasized that both the experimental carcinogenicity data
and the mathematical and biological extrapolation principles jsed
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; a'though hypothesisfomulating
33
-------
studies 1n 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 1n 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 1n
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 1s
no evidence to Justify quantum changes 1n 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 organic* 1n drinking water are an Important problem which deserves Investi-
gation, the situation today 1s not a crisis to be met with fear and precipitous
action.
IV. RECOMMENDATIONS
1. When wells contaminated with arsenic are used 1n Kokomo, the drinking
water should be monitored at least monthly to be certain that 1t
consistently meets drinking water standards. Appropriate precautions
should be taken before drilling any new wells 1n 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-analyred 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 effoft should be made to Identify the precursors) that react with
chlorine and bromine to produce the pollutants found 1n the finished
water samples. As a first step, raw waters shoul1 be analyzed com-
pletely and halogenatlon studies completed on potential precursors.
The best treatment for these pollutants may be removal of a precursor
rather than removal of the organic compounds founi 1n the finished
water supplies. Raw water samples should be takei 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 1n current use 1n 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 1n this section.
-------
1. Sampling Procedures
Fourteen bottles of water were collected at each dty. These
bottles were divided according to sample preservative as described
below. In all cases the bottles were filled completely to avoid an
a1r-Uqu1d Interface. Raw water samples were collected just prior to
chlorlnatlon. Finished water samples were collected several hours
after chlorlnatlon depending on plant flow.
Bottle ' For Preservative
a) four one liter glass two bottles for Ice
bottles w/teflon lined raw water organlcs
caps and two bottles for
finished water
organlcs
b) two 500 ml high raw and finished
density polyethylene water - metals HNCh
bottles,
c) two 250 ml polyethylene raw and finished
bottles water-nutrients H2S04
d) two 250 ml polyethylene raw and finished water
bottles cyanides NAOH
e) two 250 ml polyethylene raw and finished water CuS04/H3P04
bottles phenolics
f) two 250 ml polyethylene raw and finished 1ce
bottles water
(pH, specific conductance,
alkalinity, etc.)
Since these types of bottles had been in use in the Region for some
time ynd 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 1n a sampling bottle) were
prepared dally 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 organlcs of Interest v»as analyzed dally
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 Li tchtenberg and have

developed our own gas chromatographlc 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 mlcroware
centrifuge tube with a 14/20 ground glass Joint from a com-
pletely filled glass sampling bottle. The centrifuge tube
1s then placed on the debubbler apparatus held 1n place by
two springs as shown 1n Figure VI.

b) 'Quality Assurance for Volatile Organics
Before any samples were analyzed for the presence of
halogenated volatile organics, 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/m1n during
investigation of the flow tine. Preliminary work indicated
that longer purging times were required if the purge rate is
lowered. The data summarized in TableXIT indicates that,
with a purging rate of 80 ml/min, a purge time of 8 min.
1s 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 101 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 X1VT 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 wl 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 vg/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.
F1g .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 131 of the

cate samples are summarized 1n Table XV and defines for the reader
the precision of the total sample collection and analytical procedures
employed.
Fourteen samples were stored 1n a refrigerator after being
analyzed. A month later 1t was decided to re-analyze the samples.
The results are given 1n Table XVI.. Only the data for CHC13, and
CHC^Br 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 1s responsible for
the lower CHC13 values obtained at the latter date 1n 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.
t) Introduction
Tht procedure used 1s based on "Methods for Organic
Ptstlddes 1n Water and Wastewater," 1971, EPA publication
from NERC - Cincinnati.' ' The procedure differs from the
NERC's 1n that 1t 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 1n 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 1s used to rinse out the sample bottle and then
1s added to the separatory funnel. The samples are extracted
twice with 100 ml of 15S (v/v) ethylether /hexane, then
once with hexane, dried over N82S04, and concentrated to about
5 ml in a Kuderna-Oanish 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) 1s spiked with phorate (2 ug), placed in a
2 »1 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

PEP 1 G.C. data reduction system. A 6' x 1/4" glass column
packed with 14X SE-30 and 6X OV-210 on 80/100 mesh gas chrom
Q Is used for the original analysis and a 6' x M4" column
i
packed with 1.95X OV-17 and 1.51 0V 210 on gas chrom Q 30/ino
rtesh 1s used for confirmation. The gas chromatociraph con-
ditions are as follows: Inlet temperature - 25()°C, detector
temperature -. 240°C, oven programmed from 200°C 1:0 265°C at
4°/ra1n, carrier gas - N£ at 60 ml/min.
Portion (II) Is placed on a column of Florisll (18 g.
obtained from NERC, RTP, slurry packed with hexaie) with 1/2"
of Na2S04 at the top and bottom of the florisil.
Two fractions are collected; the first is eljted with
200 ml of 6X ethyl ether in hexane, and the second with
200 ml of SOX 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 vn'th a two-
column injector splitter, automatic sampler with 10 pi syringe,

carrier gas 1s 51 methane in argon for both columns.
A measured aliquot of each sample from the 61 ether
fraction which 1s thought to contain PCB's, as shown from
Its chromatogram, 1s removed from the vial and placed onto
a column of deactivated silicic acid (6 g, Bio-Rad Laboratories,
2.01 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 150ml of a mixture of 80% methylene
chloride, 19* hexane, and It acetonltrlle . 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

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 1n duplicates for AQC purposes.
In the laboratory, samples were analyzed 1n 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/1 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 gss 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 ee.ch pesticide. If
changes were noted, the system was recal'brated 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 1n 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
unconnected 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.

Since the adsorption and desorption efficiency on
carbon 1s 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 dally 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, 5X NaOH and the organic solvent used to extract
the solvent or toluene 1n the case of the methanol ex-
tract. The nine resulting extracts are dried over an-
hydrous sodium sulfate and concentrated to approximately
two milliters before 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 chromatcqraphy
i
techniques for further purification of this fraction are
being investigated. Compounds identified to diite are
shown below. Of significant interest is that bis-2-chloro-
ethyl and isopropyl ethers are below detection limits in
these samples.

5. Metals.
a) Analytical Procedures
1) 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 0.5X concentrated nitric
add. 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 XVIII
XIX ^and XX. - ...The listings are self-explanatory and show
that the determinations were performed with good accuracy
and precision.

11) Flameless Atomic Absorption
Procedure
Flameless atomic absorption procedures were used
for the determination of arsenic, cadmium, lead, selemium,
and silver. The Perkln-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 le-ist 3 working standards
and a reagent blank were prepared just Drior 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, selemlum, 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
1n 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
1) Ammonia - Technlcon Co. method no. 15^-71 VI was modified
to analyze samples In the range 0-1 mg/1 'Hj-fi. ~'-.e method in-
volves a hypochlorUe oxidation of an ammonia - phenol reaction
product using nltroprusside 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.
11) Alkalinity - Unaltered samples were titrated using an
automatic Fisher Titralyzer to an electrcmetrically determined
end-point of pH 4.5.
Hi) Chloride - Technicon Co. method no. 9n-70 w was modified
to analyze samples in.the range 0-200 mg/1 chloride by the addi-
tion of a twenty-five *old dilution loop. The method involves
the stoichiometric liberation of thiocyanate ic- -rom mercuric
thiocyanate to form soluble but unionized me^c-Hc chloride.
The free thiocyanate reacts with ferric ;on tc form ferric
thitcyanate proportional to the origina ;.iloride concentration.

-------
Untd cap and then heated In an oven at 150°C for 2 hours.
The amount of Cr(lll) produced by the oxidation of the
sample is proportional to the COO of the sample. The
appearance of Cr(III) 1s measured at 600 nm with Technicon
AA II equipment at 40 samples per hour. The method is
described 1n detail 1n Appendix II, which is a manuscript
that will appear 1n the July, 1975, issue of Analytical
Chemistry.
v) Cyanide - Technicon method no. 315-74W for cyanide
analysis was modified to Improve sensitivity to lnn ug/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 Ticro
technique was used to' analyze the drinking water samnles 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 evaoorated on 12 TW
aluminum pans and the residue weighed to the Dearest micro-
-76-
-------
gram to determine dissolved solids. A manuscript, submitted
for publication, describing the methods 1n detail is attached
as Appendix III.
vll) Fluoride - The EPA electrode metho'd ('fa-iual of Methods
for Chemical Analysis of Water and Wastes , p. 65, 1974) for
fluoride was used without modification.
v111) 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
1s detected by passing it through a 22 cm cell mounted in a
dual-wavelength spectrophotometer. A manuscript, submitted
for publication, describing the method is atta:hed as Appendix
IV.
1x) Nitrate plus Nitrite - Technicon Co. method no. 100 -
70 W was modified by the addition of a 5 fold dilution loop
to analyze samples 1n the range of 0 - 5 mg/k N03 •*• NC^-N.
In addition, the ammonium chloride buffer and wash solutions
were modified by adding 11.5 ml/I of 10S NaOH and 1 ml/I o*
concentrated sulfuric acid, respectively, to compensate *or
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 sulfaniianrd.: at a low pH to
form a diazo compound. This compound then couches .vith '1-1-
naph-thylethylene diamine dihydrochlori^e to "orm ^ radd;s -
purple azo dye which is analyzed at 529 ran.
-77-
-------
x) Nitrite - Techrilcon method no. 102-70 x was used without
modification to analyze samples for nitrite. The analytical
method 1s the same as fdr nitrate plus nitrite except that the
copper-cadlum column 1s deleted.
x1) pH - the pH of the drinking water samples was measured
with a pH meter equipped with a combination glass-reference
electrode.
x11) Phenol1cs - Technlcon method no. 127 - 71 W for analysis
of phenollcs was modified for samples 1n the range 0-200 mg/1.
The method Involves the distillation of phenollcs and the sub-
sequent reaction of the distillate with alkaline ferrlcyanlde
and 4 - amlnoantlpyrene to form a red complex which 1s measured
at 505 nm.
xi1i) S1Hca - Technicon Co. method no. 105 71 W was modified
by cutting the sample volume 1n half to analyze samples for
silica 1n the range 0-20 mg/1. This procedure for the deter-
mination of soluble silicates 1s based on the reduction of a
sllicomolybdate complex In acidic solution to "molybdenum blue"
by ascorbic acid.
x1v) Specific Conductance - The specific conductivities were
measured with a Radiometer COM3 conductivity meter. The meter
1s 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 - Technlccn Co. method no. 11R - 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 methyl thymol blue. Barium
chloride and methylthymol blue are added in equal molar amounts
so the excess methylthymol blue corresponds to the sulfate con-
centration.
xv1) 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 dlgestate
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 paragranh 1.
In addition, a five-fold dilution loop with i!5 ml of 10 N NaCK
per liter was used for both methods. The sanpler wash solutior
consisted of 35 ml of concentrated sulfuric acid per liter. A
manuscript describing these methods in detai is being prepared.

Quality Assurance Procedures for Inorganic Parameters.
The accuracy and precision of the analytical data were assessed
by the use of dally Instrument calibration and the analyses of duplicate
samples and Intralaboratory quality control standards. The precision
and detection limit data 1n Table XXIUshow that all of the methods
used (with the exception of phenoUcs) are much more sensitive than
necessary when compared to the drinking water quality standards (Table XXIIl).
SUMMARY
The Region V Drinking Water Study has satisfied most of the goals
of the project. It has provided the most complete 11st 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
Uchtenberg that the chlorlnatlon water treatment process produces
chloroform 1n finished drinking waters. It also provides experimental
evidence of the absence of most pesticides 1n 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 1n the next edition
of "Methods for Chemical Analysis of Water and Wastes," for some nutrient
and demand parameters, have caused great concern 1n Region V. The
Surveillance and Analysis Division has been preserving surface and waste-
waters vilth 1 ml H?S04/1 of sample for ammonia, nitrate plus nitrite,
total Kjeldahl nitrogen (TKN), total phosphorus, chemical oxygen demand
(COO), 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) 1n Chicago while
«a1pte1ned.at.arr.b1entit«nperature. In only a few cases have samples been
analyzed within the 24 fiour holding time you are recommending for the
above parameters. Typically, the holding times for sulfurlc add pre-
served samples have ranged from several days to approximately one month
from the time of sample collection.
The CRt has been actively Investigating the preservation of samples since
January of this year. Although our results are preliminary we feel com-
pelled to release the 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 1n Attachment A.
Conclusions:
1) On the basis of our work, and data 1n the literature
(Howe and Holley, 1969; Charplot, 1969; Jenkins, 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 recormended holding time for TOC (24 hours) 1s 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 1n the COO before the TOC. In
CPA F«m 13234 nu.. 4.71)

addition, on the basis of our experimental results the
recomnended holding time of 7 days for COO measurement
1s unnecessarily stringent.
3) The recommendation of one holding time for eich para-
meter for-all sample typts 1s unnecessarily cautious.
Howe and Hoiley (1969) have shown that the greatest
cause of sample Instability 1s biological activity.
Our work has verified this observation. The data In
Attachment A shows a tremendous difference In stability
between samples of high biological activity (raw sewage)
and low activity (clean surface water).
Intern 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(sulfurlc acid / sample)to be any
more effective than 1 ml/1 so the latter procedure Is also assumed.
1) Ammonia - At least one week for raw sewage and one month
for surface waters and Industrial wastes lov 1n 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 weeks 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. Vie
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
Intern recommendations outlined above should be accepted 1n Region V
pending further work. He 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 teem during the visit
to the CRL on October 15.

BRIEF
A micro stml-automated spectrophotometrlc method for determining the
chemical oxygen demand of surface and wastewaters 1s described and
compared to the standard method.
ABSTRACT
A micro sample digestion technique for the determination of chemical
oxygen demand (COO) 1s described. An automated spectrophotometrlc
measurement of the appearance of chromium (III) after sample digestion
completes the method. Adequate sensitivity at 600 run 1s achieved by
using a 50 mm flowed! to measure COO values 1n the range 3-900 mg/1.
The send-automated method 1s compared to the standard method with
respect to precision, accuracy, ease of analysis and comparability of

INTRODUCTION
The oxidation of organic and Inorganic wastes 1n a receiv-
ing water depletes the dissolved oxygen supply, which can have
a profound effect on aquatic Hfe (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 nat.ural oxygen
demand of wastes under laboratory conditions siml'ar to those
found In receiving waters (2-4). The advantage o? the BOD test
1$ that It 1s a good Indicator of the blo-degradtaility 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
dlchromate 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 COO and 800 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 vater samples, which •
-------
. 3 .
•
can be related to oxygen demand (13). However, the advantage
t
1n being able to rapidly determine TOC values 1$ offset by the
high Initial equipment cost. In addition, the Informational
content of the TOC analysis 1s 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 COO and
BOO tests measure the amount of oxygen required to stabilize
waste samples, their values Inherently reflect the original
oxidation state of the chemical pollutants.
•
The standard COO test (4) 1s widely used because 1t 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 COO has
limitations which are not inherent 1n the concept of the test.
The bacx-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 COO 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).
-------

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 dichrotnate as an oxi lant and then
measuring the excess dichrcmata spectrophotometricilly. This
procedure eliminated the tedious detection procedure of the stand-
•
ard method. The spectrophototretric procedure has !>een applied to
the analysis of water samples in which the COD was determined by
measuring the appearance of Cr (III) after rtanual digestion (25-27).
Several COO methods which use a spectropnotorcstric 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-
furlc acid used in most autcmarad systa^s 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 1n these
automated methods than 1n 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 spectrophotometrlc 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 1n Corning -«9949 16x100
m screwcap (cap #9998) culture tubes. Spectrophotometrlc measure-
ments were made with the apparatus shewn 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 500
nm Interferencs filters and 50 irm flowcells. The Standard Calibrra-
tlon control was set at 228 to attain 1000 mc/1 CCO full scale on
the recorder. A glass capillary was used as a samole probe. The
sampler was operated at 40 jamoles/hr *ith a 3:1, sample to wash
ratio.
-------

Wastewater samples with participate matter were blended
with a Teckmar Model SOT homogenUer before taking an aliquot
for analysis. An adjustable 0-5 ml Oxford pipette with dis-
posable polypropylene tips was used for allquotlng 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 arid 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
1n a 9-1 b bottle of cone HgSO.;.
Sampler wash solution was 502 sulfuric acid by volume.
A stock potassium add phthalate solution, equivalent to
10 g/1 COO, was prepared by dissolving 8.500 g of a dried portion
of NBS standard reference material 84 h 1n 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, 211, 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
art of digestion solution in * culture tube. Three and one half ml
-------
- 7 -
of catalyst solution were added carefully down the side of the
culture tube so that the-add 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 1n the same
manner and analyzed with each sample set.
All samples, blanks and standards were heated 1n an oven
at 150° C, which 1s the observed reflux temperature of 50* sul-
furlc add. After two hours the tubes were removed from the
oven, cooled, and placed 1n the Sampler IV tray.
The analytical manifold and reagents were set up as Indi-
cated 1n Figure 1. Two digested blanks were analyzed at the
beginning of each sample set to zero the baseline. A raid-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 1n calibration.
The COD val^e 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 wastewaters for CCO 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
-------

.sample digestion and concentration of reagents usec 1n the
standard method were adopted for use 1n the semi-automated
procedure described here (4).
Since the micro colorlraetrlc detection technique required
only 2 ml of digested sample the quantities of sample and rea-
gents used were reduced twenty-fold In comparison 1:0 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 rssin liners were fojnd to be
unacceptable since they were attacked by the digestion solution
giving erroneously high CCO values. Teflon-lined caps greatly
reduced this problem especially if each cap -.vas used cnly once.
Any sarrple tube which leaked, is evidencad by a black residue
on the outside of the tube, was discarded.
Uniform addition of reagents and improved precision was
achieved by dissolving all chenicals in one of twci solutions.
The catalyst solution was prepared by the standard method (4).
The oxidizing solution v/as prepared by combining potassium
dlchrotnate with mercuric sulfate and making the solution o N
with sulfuric acid to solubilizs the mercury silt. However,
the mercuric sulfaze .-/as not ccr:ple:2'y scl'js'e in the cooled,
combined reaction mixture. The hei^. of :r.e samolar :robe

was carefully adjusted so as to avoid aspirating the precipitate.
Otherwise, aspiration of the particulate matter caused severe
btMlfne noise.
SptctrophotOHMtHc Analysis. The COO of wtstewater jaaples
has been determined spectrophotonetrlcally, after digestion, by
measuring the decrease 1n Cr (VI) concentration at 352 (32) or
440 nm (19). Alternatively, the Increase 1n Cr (III) concentra-
tlonhas 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.
Holov and Zalelko 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 6CO rm, 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 ccrrmonly
used. These correspond to tv:o levels of CCD Teasurement, 5-50
jng/1 and 5C-3CO "9/T (.1). .''oore and talker found that the
working rang* of the "cw level r.odification was limited by the
diminished oxidation rozantial of the digestion solution after
505 of the cjicr,rc(r.at3 *as consumed (36).
-------
- 10 -
Due to the adequate sensitivity of the spectrophotometHc
serai-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 serai-automated meithod,
standards between 500 and 1000 rag/1 COO were analyzed 1n Incre-
ments of 25 mg/1. Potassium hydrogen phthalate was chosen for
use as a standard because of Us stability in solution and Us
complete oxidation under the conditions of the COO test (4).
The results, presented in Figure 3, show the colorinetrlc method
to.be linear up to 900 mg/1 COO.
Due to the use of 502 sulfuric acid, the original automated
manifold was constructed with acidflex tubing. However, the
system exhibited very poor hydra!ic characteristics. This problem
was alev.iated 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 50* sulfuric acid to prevent severe baseline drift
due to Teachable organic matter. Also 1:1 dilution loco was added
to the system to reduce the viscosity cf the sample stream so that
proper debubbling occurred in the flcwcell.
Precision, Acc'jr^cy i?j Detection Licrit. Since it was dif-
ficult to correct the semi-autc-ated results for r.he srrall baseline
drift, the working -atacfion 1-ir.it was defined as l:he mean bias of
the blank plus ;wo standard deviations. Eleven bl
-------

'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
11ra1t 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 samole and acid layers until the t'jbe is
capped and the fact that sample digestion occurs in a completely
closed systsm.
-------

The authors found that the ability to take a representative
aliquot of a nonhonogeneous sample was the limiting component of
analysis variability regardless of method. Precision data for
the standard COO method determined from 1 n ter-labors to-y analyses
of standard-lllce 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 1n Table II, was 101*
with a standard deviation of 42.
Comparison of Semi-Automated end 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 1n Table III. Initially the largest discrepancies between
methods occurred 1n 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 1n COO values exists between methods.
In addition, several pure organic compounds wtre analyzed to
determine if the secri-autcsated method achieved a nore 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 1n the semi-auto-
mated method, while in the standard method, volatile material
nay escape before sample oxidation 1s complete.
Interferences. One of the major problems encountered 1n
other automated COD methods 1s 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 1s
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 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 COO method, the ratio of HgS04 to
sample volume is identical to the standard method. Standards of
SCO 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 mg/1. Above
this concentration, some precipitation occurs when the dilution
water combines with the sample stream 1n 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 nra, 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 belcw 5 g/1 Fe. The
positive bias caused by high concentrations of interfering sub-
stances is routinely eliminated by diluting samples pr-icr to
analysis or correcting the reported CCO values frcm independent
determinations of chrcraiun, iron and chloride.

BRIEF
A alcro semi-automated spectrophotometrlc method for determining the
chemical oxygen demand of surface and wastewaters 1s described and
compared to tht standard method.
ABSTRACT
A »1cro sample digestion technique for the determination of chemical
oxygen demand (COO) 1s described. An automated spectrophotometric
measurement of the appearance of chromium (III) after sample digestion
completes the method. Adequate sensitivity at 600 ran 1s achieved by
using a 50 mm flowcell to measure COO values 1n 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, whi:h 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 indicator of the bio-degradcbility of a
waste. The major disadvantages of the BOO test am 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, tie chemical
oxygen demand (COD) test was developed (6). The addition of
silver sulfate (7, 8) and mercuric sulfate (9) to the acidic
dlchromate 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 COO and BCD values must be developed for
each sample type (12). -
Stenger and '/an Hall reported a very rapid method for measur-
ing the total organic carbon (TCC) content of wat;r sarroles, which
-------
. 3 -
•
can be related to oxygen demand (13). However, the advantage
In being able to rapidly determine TOC values 1s offset by the
high Initial equipment cost. In addition, the Informational
content of the TOC analysis 1s less useful than that gained
from the 800 or COO 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 COO 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 poll-joints.
•
The standard COD test (4) 1s widely used because 1t pro-
vides a good balance between the value of the Information gained
and the speed of analysis when compared to the 800 and TOC tests
m
(12). However, the standard method for determining COD has
limitations which are not Inherent 1n the concept of the test.
The back-titration of dlchromate 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 CCO hot plates
which limits the number of analyses that can be performed 1n a
day, and the difficulty of disposing of large quantities of highly
acidic mercury, silver and chromium wastes, are serious problems
for most industrial Isboratorias (15).
-------
- 4 -
Recently, there has been considerable Interest 1n 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 dichrcmate as an oxidant and then
measuring the excess dichrcmate spectrophototnetrically. This
procedure eliminated the tedious detection procedure of the stand-
*
ard method. The spectrophotcr.etric 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 COO 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 shew that these automated procedures do not
produce results equivalent to the standard method for all sample
types (33). The ^comparability of data was attributed to incom-
plete sample oxidation caused by the snort digestion times in the
automated methods. In addition, the higher cor.cenrration of sul-
furlc acid used in most automated systems requires a smaller
amount of mercuric sulfata 36 used to avoid its precipitation in
-------
. 5 -
the sample lines and flowed!. The lesser amount of mercuric
sulfate caused chloride to be more of an Interference 1n these
automated methods than 1n 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 spectrophotometrlc 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 1n Coming ?9949 16x100
mn screwcap (cap 19998) culture tubes. Spectrophotometrlc measure-
ments were made with the apparatus shewn schematically 1n 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
nra Interference filters and 50 mm flowcells. The Standard Calibrra-
tlon control was set at 228 to attain 1000 mg/1 CCO 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 parti :ulate natter were blended
with a Teckir-ar Model SOT homogenize before taking «.n aliquot
for analysis. An adjustable 0-5 ml Oxford pipette with dis-
posable polypropylene tips was used for allquoting 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 10.215 g of
K2Cr207 (dried at 1C5° C), 1S7 ml of ccnc H2S04 an-i 33.3 g of
HgS04 to 500 ;nl of water and. diluting the cooled solution to

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 1n the same
manner and analyzed with each sample set.
All samples, blanks and standards were heated 1n an oven
at 150° C, which 1s the observed reflux temperature of 50- sul-
furlc add. 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 1n 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 was obtained by direct print-
out. A typical recorder trace for standards 1s 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 .-nethod (20-22, 33). Any alternate test procedure
used to analyze -vastswaters *cr COD must produce results equiva-
lent to or bettar than :he cur-ent standard met.iod (35). There-
fore, to insure data ccncarability the temperature and length of

.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 ccnta.Tination from large glass surfaces
was consequently reduced.
Screw caps with phenolic resin liners were found to be
unacceptable since they were -itiscked by the digestion solution
giving erroneously high CCD values. Teflon-lined caps greatly
reduced this problen especially if each can -.-.as u:;ed cr.ly once.
Any sample tube which lacked, is evidenced by a black residue
on the outside of the tube, v/as discarded.
Uniform addition of reagents and ircoroved precision was
achieved by dissolving r.ll chemicals -in cne of two solutions.
The catalyst solution was prepared by tne standard method (4).
The oxidizing solution was prepared by chaining :ctissium
dlchrcmate with merfjr-c sulfate and -naking the solution 5 N
with sulfjr-'c 3c:c to sclubilize :r.e lerrjry salt. However,

was carefully-adjusted so as to avoid aspirating the precipitate.
Otherwise, aspiration of the participate matter caused severe
baseline noise.
Sp€$troohotometr1c Analysis. The COO of wastewater samples
has been determined spectrophotometHcally, after digestion, by
measuring the decrease 1n Cr (VI) concentration at 352 (32) or
440 noi (19). Alternatively, the Increase 1n Cr (III) concentra-
tlonhas been measured at 600 (27) or 650 nm (25). All of these
authors found the spectrophotometrlc procedure to be easier to
perform than the manual tltratlon.
Molov and Zalelko showed that better sensitivity could be
achieved by measuring the decrease 1n Cr (VI) concentration than
the Increase In Cr (III) concentration (23). However, the preci-
sion of ..a method based on measuring the decrease 1n Cr (VI) absorb-
ance 1s very dependent on the reproducebillty of reagent addition.
This problem was avoided and adequate sensitivity achieved by
measuring the appearance of Cr (III) at 6C3 rrn, using a 50 ran
flowcell, and the scala expansion capability of the Technicon
colorimeter.
In order to increase the sensitivity of the standard method,
two different concentrations of oxidizing reagent are ccrrnonly
used. These correspond to tv/o levels of CCD msasurenent, 5-50
nig/1 and 50-oCO -g/1 (11). ,'taore and 'Jalker found that t:ie
working range of the lew Isvel modification was limited by the
diminished oxidation pocaniial of the digestion solution after
5C2 of the iichrcmata 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 COO 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 te;t (4).
The results, presented in Figure 3, show the colorime-ric method
to be linear up to 900 mg/1 CCO.
Due to the use of 5C« sulfuric acid, the original automated
manifold was constructed with scidflex tubing. However, the
system exhibited very poor hydra"ic character-sties. This problem
was aleviatsd by replacing the scidflax tubes with ty;on au~p
and transmission tubing. The reorder trace in Figure 2 was
undamped. The entirs system was cleaned for about I/' hour before
first use with 50* selfuric acid to prevent severs baseline drift
due to Teachable organic :iittar. Also 1:1 dil-j-ion locc was added
to the system to reduC3 tra viscosity of the sample 3 :r*~~. so that
proper debubbling ccc-jrred in the flcwcsll.

'obtained was 1 mg/1 with a standard deviation of 0.8 mg/1 COD.
These values were used to define the detection Hm1t at 3 mg/1
COO. This number compares quite favorably with the detection
limit of 5 mg/1 COO 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 serai-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 COO
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 stap.
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 ccrnoletely
closed systam.
-------
- 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-!1ke 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 1n "able II, was 101 *
with a standard deviation of 41.
Comparison of Seni-Automated and Standard Methods. A variety of
surface and wastewater samples were analyzed by both the standard
and serai-automated COO cethods to determine the comparability of
data. These samples included raw and treated sewage, industrial,
chemical and food procass wastes. Results comparing the two methods
are shown 1n Table III. Initially the largest discrepancies between
methods occurred in samples which contained la-ge quantities of
particulars 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 1n CCO values exists between methods.
In addition, several pure organic cctnpcur;cs were analyzed to
determine if the semi-autcna:ad Tathcd achieved a rr.crs cc^olete

digestion than the standard method. The experimental results
and calculated maximum theoretical COD values are shown In
Table IV. Tht 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 1n the semi-auto-
mated method, while 1n the standard method, volatile material
nay escape before sample oxidation is complete.
Interferences. One of the major problems encountered 1n
other automated COO methods 1s 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 1s
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 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 se-ni-automated COO method, the ratio of HgSC4 to
sampl- volume is identical to the standard method. Standards of
500 mg/1 CCD *ere spiked *ith varying amounts of chloride in
-------
- 14 -
order to determine the limiting concentration at which the inter-
ference was significant. The results, shown 1n 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 1n the automated system,
which results 1n a noisy recorder trace. If 1t 1s necessary to
routinely analyze samples containing between 1000 and 2000 mg/1
chloride, the dilution loop can be removed. A1r 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, 3, 36).
The presence of Cr (III) in a water sample gives an apparent
COD of 1.39 times the concentration of chrcniun. Also, a potential
Interference from iron was investigated by spikir.c standards of
500 mg/1 COO with increasing amounts of ferric iron. The results,
presented 1n Figure 5, show no apparent COO below 5 g/1 Fe. The
positive bias caused by high concentrations of inisrfering sub-
stances is routinely eliminated by diluting sa.r.pl ;s ?r:cr to
analysis cr correcting the reported CCD values fr:m 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 ug/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 ug/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 '.s given. Twenty samples and/or
standards per hour can be analyzed asing this method.

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

EXPERIMENTAL
Apparatus. All glassware used In this work was boroslHcate
glass. Standard mercury solutions were prepared 1n volumetric flasks
with glass stoppers. All glassware was first washed with water, soaked
for two hours 1n a IX potassium permanganate solution, soaked for an
additional two hours 1n a 1:1 mixture of concentrated nitric and sul-
fuMc adds, 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. KNO^ followed
by several rinses with doubly deionized water was sufficient. No traces
N of mercury were observed 1n these flasks. All domestic and industrial
waste samples were stored 1n high density polyethylene, 1-liter screw-
cap bottles with polyethylene lined caps and preserved to give a final
concentration of 0.52 HNC^. Liquid transfers for dilution purposes
were made with Eppendorf pipets of 0.1, 0.25, 0.5, and 1 ml capacity.

1. Spectre Products Mercury Analyzer Model HG-2
2. Perkin-Elmer Model 56 multi-range chart recorder
3. Harmonically smoothed voltage stabilizer
4. Technlcon Auto-Analyzer Unit consisting of:

The operating principle of the mercury analyzer is based upon
o
balancing the intensity of the mercury line at 2537 A fron 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 "8" 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 t.he 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 th<» inlet and
exit tubes as close as possible to the quartz windows so as to decrease
-------
the dead air space 1n the vicinity of the window. In order to compensate
for the factor of four decrease 1n signal strength caused by these modi-
fications, 1t 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 mm/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:
1. Concentrated sulfuric acid; obtained from Baker and desig-
nated a$ "suitable for Hg determination".
2. lOt stannous chloride solution; prepared in a solution
10t1nHCl.
3. IX potassium permanganate solution; a fresh stock solution
was prepared every three weeks.
4. 2t potassium dichromate solution.
5. 31 hydroxylamine hydrochloride; prepared in a solution
3% In sodium chloride.
6. At 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 wg/1 stock solution prepared from

solution 9 above. All standards were prepared in a

In the range 0.05 - 6.0 ug/1 Hg are placed 1n a sample tube (prerlnsed
with the same solutions), and transferred to the sampler. For all
samples judged to be high In mercury I.e. 0.5 - 6 ug/1, only standards
1n that range are used. For low level mercury determination I.e. less
than 0.5 ug/1, standards 1n the range 0.05 - 0.5 ug/1 are used, and
the mercury analyzer 1s set at Us 10X scale expansion. In addition,
a recorder scale expansion (a factor of 2) is used for runs with mercury
concentrations 1n the range 0.2 - 3 ug/1. Samples to be analyzed are
then placed in the sampler while the standards are running. Standards
were prepared fresh dally from the stock solution and analyzed by the
system before and after each run 1n 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 (0.05X HN03 and 0.05S I^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 ug/1 Hg for samples with less than
1 ug/1 Hg, and with 2-3 ug/1 Hg for samples containing 1-4 ug/1 Hg.

All staples containing high concentrations of paniculate matter
were first homogenized using a Techmar Co. high speed homogenlzer model
SOT. In addition, samples were stirred before and during sampling.
After the analyses are completed, all lines with the exception of
the sulfurlc add line are placed In a It HNOj solution until all reaqents
are completely flushed out. This Is followed by placing the sulfurlc
add line 1n the wash. All the lines are then flushed for 10 rain, with
32 NHjjOH'HCl to remove any build-up of manganese codes. This 1s then
followed by flushing the system with IX HN03 for a period of 20-30 min.
The above flushing Includes all colls In and outside the high temperature
bath. For all experiments, using I^S^ or K2Cr2°7 as oxidizing agents,
the system was flushed with a IS HN03 solution for 20-30 min.
-------
SYSTEM DEVELOPMENT
During the early stages 1n 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 our4 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
1n 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 vg/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 cm-Vmin. 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 cnr/min of air. Peak separation, however, decreases
with the decrease 1n air flow.
Preservation of Samples and Standards. 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 1s currently unknown, several interpretations
have been given. The absorption of mercury on th<» surface of the con-
tainer 1s perhaps the most common of these Interpretations. The amount
of mercury lost from aqueous solutions decreases, however, when the
sample 1s. stored in acid solution. " Feldman showed that mercury

standards preserved In a solution 52 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 1n environmental samples, several
j
solutions were prepared and analyzed over a one month period. Table II
gives data collected on samples prepared in deionlzed 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, 0.5X HNOj preserved,and 0.5% HNO-j -
0.05X I^C^Oy preserved solutions. Both polyethylene and glass bottles
were used for the unpreserved samples. All other samples were prepared
1n polyethylene bottles. The mercury content of all samples was first
analyzed. Each sample was then spiked with a known amount of Hgd2»
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
delonized water) lost 20t of their strength within 10 minutes of prepar-
ation and 60* over a 10 day period. Standards prepared in 0.5S HN03
lost 6X and 3W 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 3-55 higher. This could be attributed
to the presence of trace amounts of Hg in sulfuric acid. Increasing the
-------
acid concentration up to 6* resulted in a mercury loss of 202 over a in
day period. The preservation of standards in a solution containing 0.5'/
HN03 + 0.05* K2Cr20;, however, resulted in no significant mercury loss
over a four week period. Similar results were obtained for standards
stored 1n borosllicate glass, with a slight increeise 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 - 0.05* K2Cr207. Although
unpreserved solutions of the same samples exhibit Hg 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 partlculate matter. The
stability of samples preserved in 0.5* HN03 - 0.05X <2Cr2°7» however,
was Independent of the partlculate 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 sample> should be preserved
In 0.5* HN03 - 0.05S K2O207.
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 0.52
HMO? - 0.051 K2Cr207 solution. This 1s preferred over, say, a 24 hour
non-acidified compos it 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 0.51 HNO^ - 0.051 <2Cr2°7 was added to a neutral aqueous solution
of HgCl2 (2 wg/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 1n the samples prior to the addition of the
spike (HgClj), shows that the n1tr1c-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 vg/1 Hg. All data in the range 0.05 - 0.5 vg/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 - 5.0 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 1s 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 5 absorption graphs are generally non-linear.

RESULTS AND DISCUSS IOf IS
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 (F1g. 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 donu 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/l, 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 ug/1 is 0.05 yg/1. The de-
tection limit could be decreased beyond the 0.05 yg/1 level to perhaps
0.02 ug/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 partlculate 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
partlculate 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 1n 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 SnClo will not reduce organic mercury under the exper-
imental condition given. It should be mentioned here that it was not
-------
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 301 recovery of the mercury present.
Potassium persulfate alone was sufficient to recover all the mercury
present. Variation of the concentration of l^S^Og between 0.5 - 5£ did
not alter the results obtained for methyl mercur c chloride. Since
the variation of the flow rites of reagents and/or the total volume of
solution 1n 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 115 HgCl2- This
was established by treating a 100 yg/1 sample of CH3HgCl with SnCl2
and observing an absorbance level 15 of the expected absorbance.
The variation of the concentrations of the various reagents,
however, affected the data obtained for real sairples. It was thus
observed that there is a direct correlation between the chemical
oxygen demand (COD) and the amount of persulfatj and/or'permanganate
required to completely oxidize all organic mercery present. The COD
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
501 H2$04 solution with a Ag2S04 catalyst. Since both S208 and Mn04
arc excellent oxidizing agents, all organic matter oxidized by dichromate
should also be oxidized by persulfate or permanganate and hence the
correlation between the COO of the sample and the concentration of
these reagents. It was thus observed that the suggested concentrations
of 0.5t KMn04 and 0.5X ^£$203 by Bennett et. al . , are insufficient
for most samples treated 1n this laboratory. In the present system,
a 4X K^OS (F1g> *) 1s 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 KMn04
concentration would require a large increase in the hydroxylamine
needed to reduce excess MnO^". Increasing the persulfate concentration
by the use of up to 155 (NH^SgOg 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 90S of water and waste-
water samples that come to this laboratory have a COO value of less
than 500 mg/1, it was decided that a It KMn04 and/or 42 K2S20g solutions
are sufficient. Samples with much higher COO levels (above 700 mq/1)
should therefore be diluted. It was also observed that spiked samples
with high COO 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
-------
18
were Included for experiments performed using persulfate alone, persulfate-
d1chromate, 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 1s sufficient as a digestion reagent. Per-
haps the main purpose for permanganate in these experiments 1s Us five
electron oxidation property as compared to the two electron step for per-
sulfate. The electrode potential for the S2<>82~/S042~ couple is 2.03 V
while for the MnO^/Mn2* couple 1s 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^" .ilone results in a maximum
of 3W recovery of CH^HgCl 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 MnO^ might

be required for the oxidation of some interferences such as l^S. Since
persulfate is a strong oxidizing agent, it appears that the permanganate
will not be required for this purpose. In addit on, it was observed
that sulfide concentrations as high as 20 mg/1 (as NazS) do not interfere
with the recovery of inorganic mercury added to distilled water. This
result was obtained in experiments using persulf.ite, persul fate-pennanganat*
-------
19
and persulfate-dfchromate combinations as digestion solutions. At higher
sulffde 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 1n concentrations of up to 5000 mq Cl"/l in all three digestion
solutions. Residual chlorine results in a positive interference, when
the K2S2°8 manifold is used. For these samples, a solution 32 in
NH^H'HCl-NaCl 1s to be added to the sample stream immediately after
the digestion step at the rate of 0.3 ml/mfn. CuSffy did not interfere
fn 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 0.5S. Major interferences were observed,
however, from benzene and toluene. A maximum tolerance of SOOyq/l was
obtained for these compounds. The above illustrates that the use of
I^SgOs 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 KMn04 are eliminated.
The present method is suitable for the separate determination
of inorganic and organic mercury. For this purpose, the inorganic mercury
1s determined by the removal of all reagents except for the Snd2 solution

used for the reduction of Hg6 . The temperature of the system is maintained
at room temperature, and the inorganic mercury concentration is read off

a calibration curve made of known concentrations of HgCl? run under
the sane conditions. Inorganic mercury as determined by this method
Is defined as all mercury compounds that are reduced to elemental
mercury by SnCl2 without predlgestlon 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 incrqanlc 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-FIITRABIE AND FILTRABLE RESIDUES
J. Carter, Madellene T. Huston and Oliver J. Logsdon II
April 18, 1975
-------
ABSTRACT
Rapid, micro methods for the determination of non-fHtrable
and fUtrable residues are reported. Non-flltrable residue analysis
of wastewaters 1s 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 1s completed within ttn minutes. FUtrable residues are
determined on a 100 ul sample which 1s 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-f1ltrable and filtrable residues
are among the oldest determinations 1n water analysis. While old,
residue analyses remain Important 1n assessing the quality of waste ,
surface and potable waters. At least one residue parameter 1s
Included 1n a 11st of significant parameters for assessing the quality
of effluents from ea
-------
of a Cahn micro balance 1n 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 1s 11QOC.
A substantial amount of work has been performed on improving
the standard Gooch crucible-asbestos mat procedure for the deter-
io-i«»
mination of non-filtrable residues. Chanln et al., have Iden-
tified the major difficulties with the asbestos mat technique as
being due to variations 1n 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
u
results.
10 u
Chanln et al., and Nusbaum simultaneously reported similar
non-filtrable residue methods using glass fiber filters which greatly
reduced problems with mat preparation. Engelbrecht and McKlnney
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
procedure. Three glass fiber filtration techniques were compa
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 flltrable residue analysis.
A fast, efficient and accurate method for determining non-f1ltrable
residues that combines • minimum of filter handling with rapid
filtration 1s reported 1n this paper. A rapid method for deter-
mining flltrable residues using only 100 ul of sample 1s also reported.

METHODS
Apparatus^ All weighings were performed on a Mettler ME22 electronic
mlcrobalance equipped with BE22 control and BA25 digital display units
and & 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 urn standard polycarbonate membrane filter was chosen for routine
use. Sample filtration was performed with a Mill 1 pore thirty-place
membrane sampling manifold using 15 x 125 mm culture tubes to receive
*
the filtrate. Liquid transfers for non-f1ltrable residue analysis
were performed with a 1-5 ml or 5-10 ml Oxford Laboratories Macro-Set
plpet 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 Nad to be 400 and 500 mg/1. Non-uniform
samples were homogenized with a Tekmar model SOT.
Non-rFntrable Residue. Weigh the Nuclepore filters to the nearest
mlcrogram directly out of the box. Pass the filters about 1 inch over
the Po 210 ionizing source 1n the weighing chamber to reduce the
electrostatic charge. Place the weighed filters in numbered 60 rnm
aluminum weighing dishes until they are to be used. Wash and dry t'he
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 1n distilled «ater 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 1n ten minutes and re-fliter 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 1n duplicate and the two flltrahle residue control
standards (also used as blank filters) per set of samples. When
filtration 1s 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-f1ltrable residue
values are corrected for the change 1n blank filter weights. The cause
for a blank of more than 0.01 mg should be investigated before reporting
the results.
Flltrable Residue. Heigh the Cahn 12 mm diameter aluminum pans to
the nearest mlcrogram and place on a numbered Coors spot plate. Trans-
fer one hundred ul of each sample to the residue jishes with an
Eppendorf plpet. Analyze the A and 8 control standards just like t^e
real samples. Carry two blank pans tnrough the drying and weighing
process. Correct final flltrable res'due values for the change in
blank pan weights. The cause for a b.ank of more thar 0.003 rcg should
-6-
-------
be Investigated before reporting the results,
RESULTS AND DISCUSSION
Non-Flltrable Residue Method Development. The primary considerations
In developing a new non-flltrable 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 qlass fiber and membrane
filters easy to use but of limited loading capacity) especially the
latter ones. One proposed solution to this problem 1s 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 0.05rag (using ln 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.
-------
Filter Stability. The two major causes of filter instability are
weight loss due to wash-out or "media migration" during filtering16 l8
and the volatilization of filter material during the drying process.
The bias Introduced by "media migration" during sample filtration
can be eliminated by pre-wash1ng the filter.* However, this In-
volves an extra step 1n the analytical procedure. The thermal
Instability problem exists mainly with the membrane-type filters and
19
has only been resolved by drying 1n a desiccator. However, this
procedure 1s 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 s:nal1 amounts of
residue, an undetected weight loss from a filter cm significantly
bias the results. Ten filters were evaluated for their stability
upon filtering 10 ml of water and drying at 105°C ror 1/2 hour. The
results in Table I show the weight losses for threij binderless glass
fiber filters (Reeve-Angel 934 AH, Gelman type £ and Millipore AP4^)
two glass fiber filters with an acrylic resin binder (Milllnore AP15
and AP20) and five different membrane-type filters (Nudepore,
Millipore MF, Gelman TCM, MllUpore HATF, Gelman AH1200).

a These values are based on ten replicate experiments with each type of filter.
The filters were pre-weighed, exposed to a in ml deionized water filtration,
dried at 105°C for one-half hour and re-weighed.
-------
The mean weight loss and the standard deviation cr weight loss based
on ten replicates were very similar for the three binderless glass
filters." The weight loss, 1f unaccounted for, would bias the results
by an average of 11 t 5 mg/1 at the 952 confidence level. While the
mean weight loss for the blndered and unhindered 'Miters 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 blndered 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 ami 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. Prewashlng the glass fiber

loss. Prewashlng 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 listea

a These values are based on ten replicate experiments with each type of filter.
The filters were pre-washed three times with in ml of water, dried at 105°C
for one-half hour and pre-welghed. They then were exposed to a in ml water
filtration, dried at 1C5°C-for one-half hour and re-weighed.

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, "herefore, the glass
filter* 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 Ml 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 partlculate 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*, 1n

weight.19 They also showed weight gains up to 805 for particulate-
laden glass filters at 1005 relative humidity. However, at relative
humidities below 555 the weight gain of three different samples was
less than 15. A weight gain of only 0.2** has bten reported for

combined with the low tare weight of the

filter were the deciding factors 1n choosing the Nuclepore filter
for routine use. If cost 1s a serious consideration, then pre-washed
glass fiber filters can also be substituted. Whichever filter 1s
used, 1t 1s 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 f1l
Non-flltrable Residue Methods Comparison. The data in Table III compare
2 7
results using the micro method and the standard method. ' The ratio
of the micro (using the Nuclepore filter) to the standard method results
1s 1.04 ± 0.37 which 1s not significantly different from one (T-test,
a * 0.05). Smith and Greenberg also reported no statistically significant
bals 1n 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 MUlipore
AP20 filters is 1.07 * 0.11, which is not significantly different from
one (T-test 0 » 0.05). However, the results from the Nuclepore filters
are slightly greater than from the glass filters. Cranston and Suckley
reported that both Nuclepore and gUss filters quantitatively retained
2 um beads, whereas the retention of 1 -m beads was 93 and 267', respec-
18
tively. Therefore, filtering the same volume o* a wastewats*- througn
Nuclepore and glass filters of the same diameter snould produce higner
results for the former filter. The magnitude of the dif-'erence 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-f11trable residue concentration. Obviously, the larger the
volume of water filtered, the greater the amount of residue collected
and the more difficult 1t 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
u
glass fiber filter after filtering sea water. In addition, if
enough residue was collected to act as a pre-fliter, 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-
flltrable residue results with increasing sample volume. The largest
volume filtered corresponds to no more than 3 mo 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 tne paper
industry report correspond to a 10 mg residue on a 21 mm fliter with
filtration times over 2 hours. Obviously, the pacer -'ncustry f'te-s
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 samcle. Any fil-er
that becomes clogged must be discarded to avoid erroneous results such
as those reported in the paper industry report.21
-15-
-------
Initial work to dtflnt the precision of tht method revealed poor
duplication of results for samples with non-unlfjrm particulate
matter. Thereafter, all samples with non-unlfonn partlculate matter
were homogenized with a Tekmar SOT blender. In Drder to show that
the process of homogen1zat1on does not alter the non-f11trab1e 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 t 8.0 mg/1) show that the mean results are not
affected but the precision 1s Improved by blending the samples.
The precision of the micro method on the variety of sample types
studied 1s 3 mg/1 below 50 mg/1 non-flltrable residue and 9 mg/1
above 50 mg/1 at the 95S confidence level. The average coefficient
of variation for all samples 1s 4.W. Smith and Greenberg reported
a coefficient of variation of 4.2* using the standard method.
The absolute detection 11«1t of the method 1s 0.01 mg (37). This
corresponds to 1 mg/1 for a 10 ml sample volume.
Flltrable Residue Method Development. The method of Allen and Sacon
was evaluated for use 1n combination with the micro non-f11trab1e
9
residue method described previously. Their method used 50 ul 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 ul 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 constltutents 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 1n 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 1s 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 FUtrable 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 resjIts,
0.99 ±0.18 at the 95* confidence level, 1s not significantly
different from one (T-test. * * 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, 1s 0.0021 m<|. This corresponds
to a detection limit of 21 ag/1 using a 100 ul sample volume.
There is no method of assessing the accuracy of filtrable residue
determinations on real samples. Howard and Sokolof* showed that the
loss of some chloride and nitrate are unavoidable 1* the determination
of filtrable residues. However, the A and B control standards were
used to evaluate day-to-day bias in results. cor 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 1n Table V is 0.62 ± 0.08 at the
955 confidence level. This ratio corresponds ve'-y closely to that
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, -or waters high in
acidity or alkalinity the ratio can be .nucu 'ower t^an 0.62. The
cause of a filtrable residue to conductivity -atio o^ts'je of ^.62 : ?.'
should be investigated before any results are "gpcrtec.
