technology.    Elimination  of traditional grouping
was  consciously   planned  to  foster    technology
transfer   and a maximum  interface   in  related
fields.  The  five series are:

   1.  Environmental Health Effects Research
   2.  Environmental Protection Technology
   3.  Ecological Research
   i*.  Environmental Monitoring
   5.  Socioeconomic Environmental studies

This report has been assigned to the ENVIRONMENTAL
PROTECTION    TECHNOLOGY   series.    This    series
describes   research   performed  to  develop  and
demonstrate    instrumentation,    equipment     and
methodology   to   repair  or  prevent environmental

                              ABSTRACT
Gas chromatographic analysis of water and bottom mud sediment samples
collected monthly during a one-year period from sites on the Maumee, Portage,
Sandusky, Huron, and Grand River systems indicated only very infrequent and
sporatic occurrence of minute concentrations of pesticide residues.  Samples
were analyzed for organochlorine and organophosphate insecticides and for
triazine and chlorophenoxy acid herbicides.

Concentration of residues in the few positive analyses were generally less
than 10 parts per billion for detected insecticides and less than 50 ppb
for triazine herbicide.  Diazinon, dieldrin, and the DDT family of compounds
were the most common insecticides detected.  Atrazine was the most often
detected herbicide.  An indication of chlorophenoxy acid herbicide residue
in one water and one bottom sediment sample was very questionable.  The
insecticide residues were generally associated with bottom sediment, whereas
atrazine was associated with both water and sediment samples.

The association of pesticide residues with particular river sites and sampl-
ing periods was inconsistent although limited correlation between residue
occurrence and the early spring agricultural soil preparation and planting
season was observed at one or two sites on two rivers.  No valid basis
was provided to adequately assess the agricultural versus municipal sources
of pesticide contamination.  During the period of this study, it appeared
that pesticide contamination of northern Ohio rivers was negligible and
the contribution to pesticide pollution of Lake Erie was insignificant.

This report was submitted in fulfillment of Project No. RF 3256-Al and
Contract No. 13020 EBL under the sponsorship of the Office of Research
and Development, Environmental Protection Agency.

                              CONCLUSIONS

 Based upon the experimental design and the analytical results of this
study, the contribution of agricultural and municipal sources to the
pesticide residue pollution of Lake Erie in 1971-1972 was negligible
and insignificant.  The results of the study provided no real basis for
comparing the pesticide pollution contribution from agricultural use of
pesticides to that attributed to municipal, residential, and industrial
use.  Termination of the study after only one year of sample collection
seriously curtails the reliability of making any valid evaluation of the
actual situation.  A certain percentage of the experience, technique, and
data of the first year could have very profitably been utilized in making
adjustments so that subsequent year's procedures, etc., would have pro-
vided for more valid and meaningful evaluation.

The data indicate that at the times of the sampling on the five rivers
there were no significant problems with pesticide contamination.  The very
few positive residue values obtained for atrazine or simazine at generally
less than 50 ppb and for diazinon and dieldrin at less than 10 ppb indicated
some association of residue in the streams during the spring soil prepara-
tion and corn planting season.  If pesticide residues were to drain from
agricultural land due to runoff from rainfall, etc., this is one particular
season of the year that some contamination of water ways could be expected
because it is the season during which a large percentage of pesticides are
used and the vegetative cover offering protection from soil erosion during
rainfall is at a minimum.  Only in the case of occurrence of triazine herbi-
cides was there noticeable correlation of residues between water and bottom
sediment samples and with subsequent sampling at the particular sites at
the later 2 week or 1 month interval.

The data obtained in this study produced no indication of pesticide pollution
problems from any of the insecticides and herbicides involved.  Generally
the insecticides from these categories that might be of  concern because of
use in Ohio agriculture are aldrin-dieldrin, heptachlor-h<>ptachlor epoxide,
diazinon, and parathion.  Triazine, 2,4-D and dicamba herbicides are used in
weed  control programs.  DDT and consequently its metabolities and 2,4,5-T
are no longer used in Ohio agriculture and in fact have  had very limited
previous use for a period of several years.  Residential use of all of
these materials would be considerably curtailed because  of recommendations
and restrictions.  Some industrial use in municipalities might occur.  In
most  cases, pesticide residues could be present  in the  streams originating
from  agricultural land only in period of excessive rainfall and subsequent
movement of soil  into the streams  through  runoff.

-------
As indicated previously, the data provide no basis for assessing the
contribution of agricultural versus municipal, residential, and indus-
trial sources to pesticide pollution of waterways.  Nor with the limita-
tion of data presently available from this study is it possible to
accurately relate pesticide residues in streams with soil characteristics,
topography, cultivation, and cropping practices.

                               SECTION II

                            RECOMMENDATIONS
It is very unfortunate that this study was terminated after only year
and not permitted to continue for the three-year period designated in the
proposal.  The criteria for a one-year program would probably have been
considerably different than that of the three year agreed upon by EPA and
The Ohio State University in that the collection and concentration of
effort would probably have been changed in order to provide for more
meaningful sampling and consequent evaluation of the situation.  We learn
considerably during the first year of a relatively long-range program of
the adjustments in proposal design and techniques that will make subse-
quent procedures more adequate to meet the goals of the project.

At the present time, the data gives no basis for assessing any particular
problems in the use of pesticide chemicals either in agricultural or
municipal surroundings.  Therefore, no recommendations are made herein to
affect pesticide use practices as long as they are used in accordance
with the registration, label,and necessary precautions befitting the situa-
tion.

It is recommended that the continuation of this study be reconsidered.
Modifications in time and techniques of sampling should be considered in
order to provide for optimum evaluation of the actual situation. This
would mean more intensive sampling during the seasons when pesticides are
being used with less effort during the non-use seasons.  Better timing of
sampling to correspond with heavy rainfall and the subsequent high river
flow and also with periods of low river flow during the growing season
would provide better means for evaluating the movement of pesticide resi-
dues from the point of application to the water way systems.  Better
techniques in the procedures for obtaining more representative water
samples from large rivers should also be considered.

                               INTRODUCTION


 The well known pollution of Lake Erie  has caused a decrease  in  the  desir-
 able  commercial  fish and a deterioration in  the water quality which grossly
 affects the  recreation and water usage of the lake.  Many sources contribute
 to the pollution of this body  of water, causing it to be termed by  some  "a
 major cesspool problem" for the United States.  Concern has  been expressed
 at times relative  to pesticide contamination associated with the river
 drainage systems and the contribution  of agriculture to such contamination.
 However, the pesticide content of the  streams and rivers flowing through
 these intensified  agricultural areas of Ohio and hence into  Lake Erie has
 never been determined.  Nor have related comparisons been made  between agri-
 cultural and urban sources of pesticide contamination in these  areas.  It
 thus  becomes necessary to determine the sources and extent of pesticide
 contamination in order to provide guidelines to control and/or  regulate
 the flow of  pesticide residues via these rivers into Lake Erie.  If  agricul-
 tural lands  are  contributing significant quantities of these residues,
 research should  provide a correlation  between pesticide residues in  the
 drainage systems,  agricultural practices and soil types.  Once  the sources
 are determined and such relationships  established,  appropriate  action might
 be taken to  alleviate the problem.  This study in Ohio would also correlate
 with  work being  done in Michigan and Wisconsin to not only provide informa-
 tion  on pollution  in Lake Erie, but also provide a picture of the Great
 Lakes region.

 Considerable investigation has been and is being conducted in the United
 States concerning  the monitoring of agricultural soils and river drainage
 systems  for pesticide content.  (Health Aspects of Pesticides - Abstract
 Bulletin 1968-71 and Pesticide Monitoring Journal 1968-71).   In 1957, the
 the Public Health Service of the U.S.  Department of Health,  Education and
Welfare began a surveillance system for chemical,  physical,  and biological
water quality in relation to pollution.  This monitoring program had grown
 to 131 sampling sites in the U.S.  by 1966.   From 1959 through the winter
of 1962-1963, the residue levels of DDT,  toxaphene, and BHC  were monitored
in the water emanating from an agricultural watershed in northern Alabama;
samples being taken from both the  untreated and  treated water at a munici-
pal purification plant located at  the  river confluence (Nicholson,  et al ,
1964).  The impact of these residues on the nature  and distribution of the
zooplankton,  bottom fauna,  and fish in Flint Creek  was studied  (Grzenda,
et al, 1964).  In 1964,  a monitoring system was  initiated by the USDA at
five locations on the lower Mississippi River Delta.   In 1965,  the U.S.
Geological Survey initiated a limited  program of pesticide monitoring on
11 streams in the Western United States (Brown & Nishioka,  1967).   Also  in
1965,  a monitoring program for chlorinated  hydrocarbon pesticides  in soil
and root crops was initiated in the eastern states  (Seal,  et al, 1967).
In 1966-67,  researchers  from the Department of Fish and Game in California
 (Modin,  1969) monitored  selected estuaries  from  northern to  southern Cali-

-------
fornia to determine chlorinated hydrocarbon pesticide residues in oysters,
mussels, shellfish, and other fish species as related to offshore exposure
and to agricultural and urban areas.  As reported in Volume 1, Number 1
issue of the Pesticides Monitoring Journal, June 1967, Federal Departments
of Defense, Interior, Agriculture and HEW are in the process of initiating
and conducting surveys of pesticide content in soil, water, tissues, and of
organisms existing in such medium throughout the United States.  Results of
these surveys have been published in subsequent issues of the journal as
the data has become available.

In the water surveys conducted under the direction of the Federal Departments
indicated in the preceding paragraph, sampling sites were selected at the
mouths of major streams throughout the country and in some locations in mid-
dle or upper areas of some streams.  This monitoring program, however, did
not include any of the northern Ohio rivers that empty into Lake Erie.  The
survey also does not attempt to establish the sources of pesticide pollution.
Agriculture, because of its wide use of pesticides, will in all likelihood
bear the brunt of public disdain as the major cause of pesticide pollution
of the water resources, particularly among those who are not agriculturally
oriented or unknowledgable scientifically with the problem.

Pesticide residue monitoring on some major streams in Ohio has been conducted
by the Ohio Department of Health since 1966.  This program has been concerned
basically with water quality and consequently with trace amounts of pesti-
cides in grab samples.  No attempt was made to determine source of contamina-
tion.  The Plant Protection Division of EPA as a part of the federal monitor-
ing system has selected 312 sampling sites on cropland and non-cropland in
Ohio.  Data accumulated during the 4-year study (2 years results now tabu-
lated) will associate residue with watershed as a potential stream pollution
problem.

Our laboratory, The Cooperative Extension Service Pesticide Analytical
Laboratory, has conducted residue analysis for the past 3 years on surface
and tile drainage waters from controlled agricultural plots in a project
designed to determine the role of agriculture in stream contamination.
Such data will supplement that derived from the project reported herein
from the past year's collection and monitoring of water, bottom sediment,
and clam samples from major rivers in the Lake Erie watershed.

Programs which have been or are now underway in several states on the soil
and water monitoring program are concerned principally with DDT and related
chemical residues.  In Massachusetts (Lyman et al, 1968) the investigation
was for DDT and its metabolites in fish in all the major watersheds during
1965, 1966 and 1967.  In Oregon (Marston et al, 1968) the study centered on
the movement downstream from a watershed sprayed aerially with the herbicide
Amitrole.  In Arizona (Ware et al, 1968-1971) the study involved the movement
and persistance of DDT in the soil.  Other investigators such as Swoboda
and Thomas, 1968; Nash and Woolson, 1968; and King and McCarty, 1968, have
studied the movement of pesticides in the soil.  Bailey and White, 1964;

-------
Bailey, 1966; and Bailey, 1968 investigated the role of soil chemical and
physical properties, absorption and desorption, and climate on the relation-
ship of pesticides  in soils and drainage water.  Epstein and Grant, 1968,
studied the chlorinated pesticide content of runoff water in Maine potato
fields as affected by crop rotation.  Many other studies too numerous to
cite individually (Journal of Agricultural and Food Chemistry, 1965-1971;
Bulletin of Environmental Contamination and Toxicology, 1966-71; Pesticide
Monitoring Journal, 1968-71; and other journals) have likewise been concerned
with the fate of pesticides in soil, water, and commodities.  Although all
these studies have direct relationship to possibilities of pesticides in
the drainage from agricultural land, research is yet needed to determine
the source of stream pesticide pollution in the Lake Erie watershed and
relate it to the agricultural and urban cultural practices or waste disposal
methods, the soil types, topography, etc.

                               SECTION IV

                            SAMPLE COLLECTION
Sites for sampling water and corresponding sediment were selected at
appropriate locations representing agricultural and municipal areas along
the tributaries and the main streams of the Maumee, Portage, Sandusky,
Huron, and Grand Rivers in northern Ohio.  (See Appendices I and II)  Sites
were preferentially selected to show pesticide residue runoff from intensi-
fied agricultural areas and to contrast that with pesticide levels in the
streams after the influence of drainage systems of large communities or
cities.  Sites that would exhibit the influence of heavy industrial manu-
facturing, pesticide formulation, and barrel reclaiming areas were generally
avoided.  Sites were also selected at the mouths of the rivers as they flow
into Lake Erie and around the islands near Sandusky Point.

Water samples, bottom sediment samples, and fresh water clams (where
available) were collected from each site on a monthly basis or more often
following periods of heavy rainfall and runoff.  (See Appendix III)
Sampling was done as feasible during the inclement cold weather of late
December, January, and February (ice conditions on rivers and the lake
generally make sampling prohibitive during this period).  Water samples
were obtained with a model 1200 Ekman Water Sampler and transferred to
clean aluminum foil capped, one-half gallon glass milk bottles for trans-
port to the laboratory.  Approximately one gallon of water was collected
at each site.  Sediment samples were collected as the water sediment inter-
face from the bottom of the river at appropriate locations across stream
with a six inch model 196 Ekman Dredge.  A weighted Model 196 dredge was
used at locations in the river and in the lake where the bottom was deep.
Sediment collections were transferred to plastic bags for transport to the
laboratory and after removal of the water were transferred to large Dixie
cup type covered containers.  Clams were collected by hand from the natural
beds located in the bottom of the streams  and were transported to the
laboratory in plastic bags.  Flexibility in a sampling was maintained be-
tween rivers and sampling sites so that if problem areas arose they could
be adequately evaluated as required and modifications made in the intensity
and frequency of sampling of the particular area.

Water samples were generally extracted as received in the laboratory by the
appropriate procedures outlined in Appendix V.  The extracts were then
stored in a -20°Cfreezer until analyzed by gas chromatography for residues
of organochlorine insecticides such as DDT, aldrin, dieldrin, heptachlor,
lindane, methoxychlor, and appropriate metabolites considered of significance
in the ecosystem; for organophosphate insecticides such as parathion, mala-
thion, diazinon and others considered of agricultural importance in the
appropriate areas; and for herbicides common to Ohio agriculture including
the chlorophenoxy acids and triazines.  Bottom sediment samples were stored
in the freezer until the time schedule permitted their extractions accord-

-------
ing to the procedures outlined in Appendix VI.  Likewise the extracts were
stored in the freezer until analyzed by gas chromatography.  Clam samples
were stored in the freezer upon arriving in the laboratory.  They were not,
however, analyzed for pesticides residues in this study because of the
limited number of samples obtained.

                    SAMPLE PREPARATION AND ANALYSIS


Samples were prepared, extracted and pesticide residues analyzed by the
procedures outlined in Appendix V and VI.  Confirmation of residues was
accomplished by the comparison of gas chromatography on 2 or more columns
and in many cases two or more gas chromatographs, by determination of  p
values and in some cases by bromination.  The following gas chromatographic
conditions were utilized.

                       RESULTS AND DISCUSSIONS


 The tabulation of analytical data from analysis of water and bottom
 sediment is contained in Appendix VII.  Results for organochlorine
 insecticides, triazine herbicides, chlorophenoxy herbicides, and organo-
 phosphate insecticides are found in Table 14 through 17 respectively.
 The number of mussel samples collected was too few to be of significance
 and consequently such data is not included in the tabulation.   The river
 flow data, indicating periods of runoff caused generally by drainage from
 rainfall or irrigation,  as compiled by the Geological Survey for the period
 of time spanning the sampling is listed in Appendix IV.   Soil  character-
 istics and cropping practices associated with the general areas of sampl-
 ing are shown in Appendix II.

 The analytical methods used in this study were capable of measuring organo-
 chlorine pesticide  concentrations as low as 1.0 part per trillion in
 water and 10 parts  per trillion in bottom sediment  and in the  sub-part
 per billion range for other pesticides (although the sensitivity levels
 were established as indicated  below).   The gas  chromatography  instruments
 were capable of measuring as little as 15  picograms  of aldrin  with one-half
 scale recorder response.   Thus extremely low concentrations  of pesticide
 residue could be measured with accuracy.   At  those  extremely low levels
 of  measurement,  the background for  some  samples  sometimes  became  bothersome
 and consequently required additional  analysis with other  chromatographic
 systems  (columns and instruments  as  indicated  in  Section  V)  in order to
 determine  the  presence or non-presence of  pesticide  residue.   In  addition
 "p"  values  were  calculated in confirming  residues  (partitioning  coefficient
 of  the  pesticide between  equal volumes of  hexane and acetonitrile).  When-
 ever the resolution of the  gas chromatographic peak was doubtful  or re-
 analysis and  "p"  value calculation  still resulted in non-evaluable results,
 the  entry was  left  blank  for the particular sample and pesticide  residue
 in  question.  Astericks in place of numbers in Tables  14-17  indicate that
 the  representative  peaks  for the residue involved were observed by two or
more  gas chromatographic  systems but that  the "p" value was  slightly out-
 side  the accepted book value range and the value range determined accord-
 ing  to our  laboratory techniques.  Consequently, no residue values were
 calculated  for those particular samples and it is doubtful that any resi-
dues were present.  The letter "N" in Tables 14-17 indicate  that no
pesticide residues were determined at the sensitivity level of approximately
1 ppt in water and 10 ppt in bottom sediment for organochlorine insecticides,
and 0.1-1.0 ppb for organophosphate insecticides, 0.5-1.0 ppb for triazine
herbicides, and 0.5  to 1.0 ppb for chlorophenoxy acid herbicides in water
and bottom sediment respectively.

The occurrence of organochlorine pesticide residue in water and bottom
sediment samples is  recorded in Table 14.  Some .indication of residue was
evident in the initial analysis but confirmatory analysis by the procedures
indicated in the preceding paragraph failed to substantiate such presence.
Five water samples gave indication of residue but could not be satisfactorily
                                 10

-------
substantiated via the confirmatory process.  Several blanks in the table
of data indicate non-availability of analytical data or the uncertainity
of results as indicated in the preceding paragraph.

Seventeen of the bottom sediment samples gave positive residue indication
for dieldrin with 15 more possible (denoted by asterick) but not positively
confirmed; 11 samples contained p,p'-DDD with 7 more possible; 2 samples
contained p p'-DDT; and 4 samples contained p,p'-DDE with 2 more possible.
There was no apparent correlation in the samples for occurrence of the DDT
isomers and metabolites.  Concentrations of dieldrin ranged from 1.06
parts per billion to 17.6 ppb with an average for the 17 samples of 5.54 ppb.
Concentration of p,p-DDD in the confirmed samples ranged from 0.7 ppb
to 158.54 ppb with an average of 15.77 ppb.  All except 2 samples were
below 8.0 ppb.  The two samples containing p,p'-DDT were at 5.1 and 16.44
ppb and the range of the 4 samples containig p,p'-DDE was 2.1 to 34.6 ppb
with 3 of the samples less than 3.2 ppb.  Thus the concentration of organo-
chlorine pesticide residue showing positive in this small fraction of the
total sampling was negligible and insignificant.

The occurrence of triazine herbicide residues in water and bottom sediment
samples is shown in Table 15.  Ten water samples and eleven bottom sediment
samples gave indication of atrazine (2-Chloro-4 ethylamino-6-isopropylamino-
a-triazine) residues and 4 water samples appeared to contain simazine
(2-Chloro-4,6-bis(ethylamino)- s - triazine). Atrazine residues in such
water samples ranged from 2.73 to 69.44 ppb with an average of 23.82 ppb
and in bottom sediment from 4.47 to 95.19 ppb with an average of 43.27 ppb.
Simazine concentrations in the four samples were 26.40, 29.93, 32.40, and
238.86 ppb.  Some correlation of triazine residue was observed between
the water and corresponding bottom sediment samples in that when residues
were determined in water they were also generally found in the bottom
sediment samples from the corresponding or next adjacent sampling site.
The most common occurrence of triazine herbicide residues was associated
with the spring cultivation season and generally with agricultural related
sites.  In several cases, residues were determined in the samples from the
same site at each sampling period during May and June.  Triazines are used
quite extensively in Ohio for weed control in corn.  The occurrence of
minute traces of atrazine following irrigation or rainfall was also noted
by Schwab et al, 1970 and 1971 in studies conducted on drained research
plots at the Castalia Branch of the Ohio Agricultural Research and Develop-
ment Center.

Residues of chlorophenoxy acid type herbicides were practically non-existent
in the water and bottom sediment samples collected during this study  (Table
16).  The only exceptions were two samples; i.e. a water sample containing
an apparent residue of 7.0 ppb 2,4,5-T and a bottom sediment sample with an
apparent residue of 22.7 ppb dicamba  (3,6-Dichloro-o-anisic acid).  Initial
investigations had indicated that minute concentrations of 2,4-D and dicamba
might have been present in several samples but additional analysis on
different chromatographic systems did not confirm such occurrence. The
                                  11

-------
 vater sample was  associated with an agricultural site on  the Portage
 River in  late  June  and  the bottom sediment  sample with a municipal site
 on  the Huron River  in mid-May.  The occurrence of the herbicide  residue
 at  each of these respective sites is not explanable in that 2,4,5-T  is
 no  longer registered for agricultural nor home owner use (only for non-
 cropland) and  dicamta would not generally be associated  with municipal
 use.   The only explanation for the latter would be an industrial spill
 or  dumping or  the disposition of material from agricultural areas of the
 river.  In view  of  the  fact that no indication of dicamba  (or 2,4,5-T)
 residues  were  found at  any other locations  nor at any other sampling
 date  casts considerable doubt on the validity of the residues indicated
 above.

 The analytical data for organophosphate insecticide residues are tabu-
 lated in  Table 17.  The only valid occurrence of residue was in  the  bottom
 sediment  at two  sites on the Huron River from the May and June 1972  samp-
 lings.  Two other occurrences, one from the Maumee River sampled in
 December  and one  from the Huron River in December are not explanable
 unless some waste was dumped at those times.  Concentrations of  residues
 in  the six bottom sediment samples indicating diazinon (0,0-Diethyl
 0-(2  isopropyl-4-methyl-6-pyrimidinyl) phosphorothioate) were very low
 ranging from 3.6  to 13.6 ppb.  One sample from site No.  1 on the Huron
 River in  June  1972  indicated the possible presence of 3.3 ppb of ethyl
 parathion (0,0-Diethyl  0-p-nitrophenyl phosphorothioate).

 The results of this monitoring survey corresponds favorably with published
 results of similar monitoring by the Ohio Department of Health on major
 streams in Ohio  (1966-71).   One site each on the Maumee  and the  Sandusky
 Rivers were included in their sampling in which no organochlorine nor
 organophosphate pesticide residues were reported in 1971.  Data  for  1972
 for comparative purposes is not yet printed.

 It  is at present  impractical to relate any pesticide residue occurrences
 to  particular  areas or particular cultivation and cropping practices.  There
 are no significant differences between residues attributed to agriculture
 versus that attributed  to municipalities and industry because basically
 no  significant occurrence of pesticide residues were found at any locations.
 If  any relationships were attempted,  it would appear that triazine (sima-
 zine) in water was associated with the residential and industrial area
 of Fremont on  the Sandusky River,  but atrazine with agricultural areas on
 the Huron River systems.  Some corn acreage preceded Fremont upstream and
 sites 1 to 4 on the Huron River were associated with corn producing areas
 (See Appendix II).  As indicated before, triazines are used for weed control
 in corn.   The few occurrences of triazine (atrazine)  in mud samples are
associated generally with one particular agricultural area of the Maumee,
Portage,  Sandusky, and Huron Rivers  and were evident during the planting
and early growing season.   The residue value for site 1 on the Sandusky
River in November 1971 cannot be explained.   The minimal occurrence of organo-
phosphates pesticide residues reported,  appears to be related with one part-
icular section of the Huron River  in  which agriculture and  corn production
is the predominant environmental factor.  Diazinon is used  for insect con-
trol in corn production.
                                 12

-------
At present, it is unreaslistic to associate pesticide residue occurrence
in this study with soil and topographical characteristics.  Comparison
of the data in Appendix VII with the descriptions of corresponding sites
in Appendices I and II indicates that most sites on the Maumee, Portage,
Sandusky, and Huron Rivers were related to level or nearly level topo-
graphy; the major exceptions being some slightly rolling topography near
some of the stream depressions.  Hilly topography was more noticiable in
the Grand River watershed.  Correlation of pesticide residue data with
soil structure, drainage, etc., is not attempted at present because the
residue data are not significant and soil descriptions are not available
for all areas of particular interest.  Any such attempted correlation
would be meaningless.

The river flow data which would indicate possible periods of rainfall and
consequent drainage runoff is listed in Appendix IV.  In accordance with
the discussion of the previous paragraph, any correlation between drain-
age reflected as river flow and pesticide residue is meaningless at
present.  The main observation made is that the optimum time for sampling
as far as drainage is concerned may not have been attained, particularly
during the 1972 planting and early growing season.  Of course, other
factors such as times of soil preparation, pesticide application, cultiva-
tion, plant growth, etc., are equally as important as is drainage and
runoff in assessing the relationship of  pesticide residues in the streams
to the source of contamination.  Also, the flow data of Appendix IV raises
the consideration of more practical procedures in sampling water from
large rivers where the volume of water flowing creates great dilution
factors.  Because of such phenomenon, drainage waters from residential
and industrial areas near the mouth of a large river may be so diluted
that the analytical procedures and instrumentation used in this study
could be incapable of measuring positive values.  Any consequent compari-
son between municipal sources and agricultural sources of pesticide
pollution may be invalid.  On the other hand, measurable concentrations
of pesticide residues in the water at the mouths or large areas of the
river multiplied by the flow rate of the river could result in an inter-
pretation of residue content that is astronomically high and thus also
invalid.

It is advisable that this project be reinstituted for the remaining 2
years of the three-year proposal.  Some revisions perhaps should be
made in sampling in order to obtain samples at the optimum times and by
improved techniques.  Residue data from three years of sampling would
appear to be much more valid than that from only one year and could likely
also be more comprehensively evaluated, if the time of sampling were more
selective in schedule.  This would permit more intense sampling during
the cultivation and planting season and during periods of high runoff
following rainfall as well as at periods of low river flow.

    Procedures for Determination of Pesticide Residues in Water

                       Dr. Acie C.  Waldron
            Extension Specialist, Pesticide Chemicals
               Ohio Cooperative Extension Service
                       Ohio State University
General:

All glassware must be thoroughly cleaned, preferrably with Alconox
or Micro washing compounds, thoroughly rinsed in clean water, and
rinsed with glass distilled acetone before use.  Separatory funnels
and chromatography columns should be equipped with Teflon stopcocks
and Teflon or plastic stoppers.  Avoid any use of silicone grease or
any other lubricant on any glassware item that comes in contact with
the sample.

All solvents used must be re-distilled in all-glass apparatus or must
be purchased as pesticide quality solvents.  The reagents indicated have
been found to work most satisfactory in this laboratory.  Reagents ob-
tained from different suppliers sometimes perform differently and thus
must be checked out as to their applicability.  Aqueous reagent solu-
tions are to be made in double distilled water.

The laboratory technician should run recovery studies at various con-
centration levels in adapting the methods to his techniques.  Because
techniques and equipment varies from lab to lab the methods should be
checked out before using on a routine basis.
         Analysis for Organochlorine Insecticide Residues

Procedure 1.  (Procedure 2 differs only in eliminating the use of 10%
        and using 250 ml of water sample.)
    1.  Place 500 ml of water in a 1-liter separatory funnel (Teflon
        stopcock and Teflon or plastic stopper) and add 100 ml of 10%
        Na2S04 solution.
    2.  Add 200 ml of glass distilled petroleum ether and extract the
        aqueous phase by shaking the separatory funnel vigorously for
        1 minute.
    3.  Allow the phases to separate and transfer the aqueous phase to a
        second 1-liter separatory funnel.  (Remove as much aqueous phase
        as possible by permitting time for complete separation of phases.
        Swirl separatory funnel to dislodge water droplets on sides of
        vessel.)

    4.  Extract the aqueous phase with an additional 100 ml of g.d.
        petroleum ether.  Separate the phases as above and discard the
        aqueous phase.
                                52

-------
5.  Combine the two petroleum ether phases and backwash by shaking
    vigorously with 100 ml of 2% NaHC03 for 1 minute.  Again separate
    and discard the aqueous phase.

6.  Transfer the petroleum ether solution to a 500 ml round bottom
    evaporation flask (Generally best to carefully pour the solution
    through the mouth of the separatory funnel in order to avoid water
    pickup from the funnel stopcock and stem.)  and concentrate to
    about 20 ml volume with a flash evaporator.  The temperature of the
    water bath should not exceed 40° C.

7.  Prepare a 19 x 300 mm reservoired Teflon stopcock chromatography
    column (Kontes) for clean-up purposes by one of the two following
    procedures.

    A  1.  Place a small plug of glass wool in the bottom of the column
           followed by 4 inches of Activated Florisil (Kensington Scien
           tific Corp., 1399  64th St., Emeryville, California 94608;
           60/100 mesh, 650 C activation and pre-tested; stored in an
           oven at 140° C before use.) and 1 inch of anhydrous
       2.  Wash the column with a few mis of glass distilled petroleum
           ether, discard wash, and then add the concentrated extract
           to the top surface of the column material.

       3.  When the top miniscus of the extract reaches the surface
           of the column material, elute the column with 200 ml of
           glass distilled petroleum ether and collect the elute in
           a 500 ml round bottom evaporation flask at a rate of appro-
           ximately 1-2 drops per second.

       4.  Replace the collection flask with a second 500 ml round
           bottom evaporation flask and elute the column with 250
           ml of glass distilled benzene.

              (Note:  Check the elution chart for separation of organo-
           chlorine pesticides.  Our experience shows that Aldrin,
           heptachlor, p,p'-DDE, o,p-DDT and some p,p'-DDT elutes
           in petroleum ether and lindane, heptachlor epoxide, dieldrin,
           p,p'-DDD, the remainder of p,p'-DDT, and methoxchlor elutes
           in benzene.)

       5.  Concentrate the eluates to an appropriate volume (10-15 ml)
           by flash evaporation and inject aliquots on the gas chroma-
           tograph.  Additional concentration may be required with a
           nitrogen gas jet or cleaned air stream to obtain gas chroma-
           tographic response.

    B  1.  Place a small plug of glass wool in the bottom of the column
           followed by 2.5 inches of florisil, 2.5 inches of silica gel
           (Davison Grade 923, 100-200 mesh, stored in a 140° oven before
                             53

-------
             use.),  and  1  inch  of  anhydrous

         2.   Wash  the  column with  petroleum ether, add  the concen-
             trated  extract and elute  the column with 250 ml of 5%
             benzene in  petroleum  ether followed by  250 ml of benzene
             as in the previous procedure.  (The elution sequence
             is the  same as before except p,p'-DDT seems to elute
             only  in the 5% benzene-petroleum ether.)

         3.   Concentrate the eluates and inject aliquots on the gas
             chromatograph.)

             (Note:  Recovery values at all concentration levels were
             generally 90 to 110%.

 8.  Gas chromatographic conditions were:  Barber-Colman Series 5000
     equipped with  6  ft. all glass column packed with  1:1 mixture of
     10.4% DC-200 plus  15.1% QF-1 on Gas Chrom  Q 100-120 mesh; oven
     temperature  200° C; detector temperature 210° C (Tritium foil
     Electron Capture); injector temperature 220° C; carrier gas-
     nitrogen.

 9.  Confirmation of residues was accomplished by concentrating the
     eluates to a very small volume and injecting aliquots on an
     identical column in the same gas chromatographic oven but
     attached to a microcoulometer detector or by chromatographing
     on two or more instruments and two or more columns and calcula-
     tion of "p" values.

10.  Calculation of residue concentration based upon comparison of sam-
     ple peak areas with areas  of organochlorine pesticide standards
     analyzed concurrently each day.

                    Peak area of  sample minus  control  volume  of  sample (ml)
 Apparent p.p.m.  =  Peak area per ng  standard         x  volume  injected (ul)
                                  wt.  (vol) of  water sample

 The apparent p.p.m. is  then  corrected for  percent recovery  to  obtain
 the actual concentration.

     Analysis for  Chlorinated Acid Herbicide Residues
            (2,4-D;  2,4,5-T; Dicamba,  etc.)

 Place  250  ml of water in  a 1-liter separatory  funnel and  add 100 ml
 of a solution of  2% NaHC03 and 0.125% EDTA disodium salt  (Disodium
 dihydrogen ethylenediaminetetraacetate dehydrate  manufactured  by
 G. Frederick Smith  Chemical Co.   The  EDTA ties up calcium and  heavy
 metal  salts  on glassware which,  if in sample, would precipitate the acids.)
 Extract the  aqueous phase by adding 200 ml of  glass distilled  benzene
 and shaking  the contents vigorously for 1 minute.   (pH of the  aqueous
 layer  should be approximately  pH  8.0  at this time.)


                            54

-------
 3.   Separate the phases and discard the benzene phase.

 4.   Add 100 ml of 0.60N H2S04 to the aqueous solution in the separatory
     funnel and shake cautiously venting the funnel periodically to permit
     evolved CC>2 to escape.   (pH 1.5 - 2.0 should be condition of aqueous
     phase at this point.)

 5.   Add 200 ml of glass distilled benzene and shake vigorously for 1 minute.
     Vent funnel as required.  Separate the phases transferring the aqueous
     solution to a second separatory funnel.  Save the benzene phase.

 6.   Extract the aqueous phase with an additional 100 ml of g.d. benzene.
     Separate phases and then combine the benzene phases from the two
     extractions in a 500 ml round bottom evaporation flask that has been
     previously acid and acetone washed.

     (Note:  After the herbicide acids have been separated from water,
     care must be taken to prevent loss on glassware.  All glassware used
     from this point on, including the evaporation flasks, must be washed with
     approximately 0.05N HC1 solution and then with glass distilled acetone
     to remove all traces of HCl.  This washing removed calcium and heavy
     metal salts probably present as carbonates and also C02 present in
     distilled water, etc.  that would combine with any cations present.)

 7.   Evaporate the benzene extract with the flash evaporator to a volume of
     approximately 5 ml.  Transfer the extract to a 15-20 ml centrifuge tube.
     Rinse the evaporation flask with a small volume of benzene and add to
     the solution in the centrifuge tube.

 8.   Prepare a diazomethane methylating apparatus consisting of two 2-hole
     rubber stoppered 20 x 125 mm test tubes connected with 1/4 inch bent
     glass tubing.  The first glass tube should be connected to a nitrogen
     source and after bending on a 90° angle placed through the rubber stopper
     so as to almost touch the bottom of the test tube.   The second glass tube
     should be bent in a flat U-shape with a short end inserted through the
     second hole of the first rubber stopper (extend 1-2 inches into the test
     tube) and the long end through the second rubber stopper so as to almost
     touch the bottom of the second test tube.  A second U-shaped glass tube
     is inserted (short end) in the second hole of the second rubber stopper
     and the long end left free to insert into the sample centrifuge tube.

 9.   Place 10-15 ml of glass distilled diethyl ether in the first test tube.
     In the second test tube place 2 ml of 60% KOH, 2 ml of glass distilled
     carbitol, and 5 ml of glass distilled diethyl ether.  Prepare a new test
     tube of this nature for each sample to be methylated.

10.   Add approximately 50 mgm of Dizald reagent (yellow-orange powder - the
     quality can be quickly approximated on the end of a micro spatula) to
     the KOH-carbitol solution, connect the tubes to the nitrogen line, place
     the sample under the end of the generator so that the diazomethane-nitro-
     gen gas bubbles through the extract.


                                  55

-------
       (Note:  The first test tube cleans the nitrogen and saturates it
      with diethyl ether by bubbling the gas through the ether; the second
       test tube generates diazomethane again with the nitrogen gas bubbling
       through the solution; and the sample is thus methylated in the centri-
       fuge tube.  The nitrogen gas flow should be regulated to about 5-7
      bubbles per second.)

11.   Methylate the samples for 1-2 minutes until a faint but brilliant
      yellow color is evident and then let them stand for about 10 minutes.
      If the samples are sufficiently clean, aliquots can be injected directly
      on the gas chromatograph and analyzed with the electron capture detect-
      or.  In most cases, however, additional cleanup is required to. remove
      extraneous materials.

12.   Prepare a chromatography column (19 x 300 mm reservoired) with a
      glass wool plug, 4 inches of 2% H20 deactivated florisil, and 1 inch
      anhydrous ^2804.  (The florisil was deactivated to prevent excessive
      tailing in elution of the methyl esters.)

13.   Wash the column with petroleum ether and elute the methylated herbi-
      cides with 200 ml of 10% glass distilled ethyl acetate in glass distilled
      benzene.  Concentrate the eluate on a flash evaporator to a suitable
      volume.

14.   Inject aliquots on the gas chromatograph as discussed in the procedure
      for organochlorine insecticides.   Confirm by microcoulometry or the
      procedures outlined on page 54.

15.   Calculate the residue present by comparison to the response of methy-
      lated standards.
                    Analysis for Atrazine in Water

Procedure 1.

      1.  Place 500 ml of water in a 1-liter separatory funnel and extract
          the aqueous layer by shaking vigorously 1-2 minutes with 200 ml
          of  cleaned chloroform.  (The chloroform is cleaned by passing it
          through a large column containing 6-8 inches of Davison 923 silica
          gel.  Discard the silica gel in the column when it becomes trans-
          parent in color to chloroform.  Refill the column with new silica
          gel before further use.

      2.  Separate the phases and extract the aqueous phase a second time
          with 100 ml of cleaned chloroform.

      3.  Combine the two chloroform extracts and backwash by shaking it
          vigorously for 1 minute with 100 ml of 2% NaHC03.  Collect the
          chloroform phase in a 500 ml round bottom evaporation flask and
          evaporate with a flash evaporator to almost dryness.

      4.  Remove the final chloroform under a clean air or nitrogen gas stream.
                                 56

-------
         Dissolve the residue in benzene and inject aliquots on the gas
         chromatograph.  Both electron capture detection and flame thermionic
         detection can be used.  Electron capture with a 6%i detector provides
         the greater sensitivity but also the greatest interference.  A
         flame thermionic detector with rubidium chloride salt bead (or
         potassium chloride as second choice) is the preferred detection system.
         Several different column combinations may be used including the
         10.4% DC-200 plus 15.1% QF-1; 2%  OV-210 plus 1% OV-17; 2.5%
         OV-17; and 1.5% QF-1, all on Gas Chrom Q.

         Column temperatures should be 170-180°C; Ni63  Electron Capture de-
         tector temperature 240-245° C; flame temperature 220-225° C with
         hydrogen and carrier regulated to give adequate response according
         to manual but not excessive to cause high temperature and melting
         of salt bead.
Procedure 2.  (Quickest and simplest method.)

     1.  Place 500 ml of water in a 1-liter separatory funnel and add 100
         ml of 10% Na2S04.

     2.  Extract the aqueous layer with 200 ml of $.ass distilled benzene by
         thorough shaking for 1 minute.  Separate the phases and extract
         the aqueous phase with an additional 100 ml of g.d. benzene.  Separate
         the phases and discard the aqueous solution.

     3.  Combine the benzene layers and backwash by shaking 1 minute with
         500 ml of 2% NaHC02-  Separate the phases and discard the aqueous
         solution.

     4.  Place the benzene phase in a 500 ml round-bottom evaporation flask
         and evaporate to the desired volume with a flash evaporator.

     5.  Inject aliquots of the concentrated extract on the gas chromatographic
         column and detect with a electron capture or flame thermionic (KC1 or
         rubidium chloride salt bead) detector as in the previous method.


   Determination of Organophosphate (and Organochlorine) Insecticides

Procedure 1

     1.  Place 500 ml of water in a 1-liter separatory funnel.  Add 200 ml
         of glass distilled acetone and mix thoroughly.  Add 10 grams of
         ^a2^4 an(^ again mix thoroughly.
     2.  Extract the insecticide residues with 200 ml of glass distilled
         petroleum ether by shaking the funnel thoroughly for 1 minute.
         Separate the phases and extract the aqueous phase a second time with
         100 ml g.d. petroleum ether.  Separate the phases and discard the
         aqueous solution.
                                 57

-------
     3.  Combine the petroleum ether phases and backwash by shaking with
         500 ml of 2% Na2SO,.  Separate phases, discard the aqueous solution,
         and transfer the petroleum ether extract (pour from mouth of funnel)
         to a 500 ml round bottom evaporation flask.

     4.  Concentrate the extract to an appropriate volume and inject on a gas
         chromatographic column (oven temperature approximately 180°C; flame
         and temperature of detector adjusted for optimum sensitivity) and
         detect organophosphate residues with the flame thermionic detector
         (KC1 bead).  The columns indicated in earlier procedures are generally
         satisfactory.


Procedure 2

     1.  Same procedure as above through step 3.

     2.  Concentrate the petroleum ether extract to approximately 20 ml with
         a flash evaporator (water bath temperature 49° C) and then trans-
         fer extract to a prepared chromatography column.

     3.  The chromatography column (19 x 300 mm reservoired) is prepared by
         placing a small glass wool plug in the bottom followed by 2-1/2
         inches of deactivated florisil (2% H20 added), 2-1/2 inches of
         Silica Gel Davison Grade 923, and 1 inch of anhydrous Na2SO,.  Wash
         the column with g.d. petroleum ether before adding the sample.

     4.  Elute the sample on the column with 250 ml of glass distilled benzene
         to remove the organochlorine insecticides,  change receiving 500 ml
         round bottom flasks and elute the column with 200 ml of 10% ethyl
         acetate in benzene to remove the organophosphates.

     5.  Concentrate the above eluates with a flash evaporator to a desired
         volume and inject aliquots on the gas chromatograph.  Organochlorine
         residues can be detected with the electron-capture detector and
         organophosphate residues with flame thermionic and electron capture
         detectors.


Prodecure 3  (For organophosphates that require oxidation to the oxon or
              sulfone for gas chromatographic determination.)

     1.  Same procedure as above to step 5 of procedure 2.  Evaporate the
         eluate to just dryness on the flash evaporator.

     2.  Dissolve the residue in 15 ml of cleaned chloroform and add 5 ml of
         10 mg/ml metachloroperbenzoic acid in chloroform.  Swirl the flask
         and let stand for 15 minutes.

     3.  Place the chloroform solution in a 125 or 250 ml Teflon stopcocked
         separatory funnel and add 25 ml of 10% sodium meta-bisulfite.  Shake
         the  contents  in  the funnel vigorously  for one  minute and  transfer
         the  chloroform phase  to a second  separatory funnel.


                                 58

-------
^«  Add 25 ml of saturated sodium bicarbonate to the funnel and shake
    with the chloroform phase vigorously for 1 minute.  Transfer the
    chloroform layer to another 125 ml separatory funnel and wash two
    times with 25 ml aliquots of distilled water.

5.  Transfer the chloroform phase to a 250 ml round bottom evaporation
    flask and evaporate just to dryness on the flash evaporator.

6.  Dissolve the residue in a known amount of glass distilled benzene
    and inject aliquots on the gas chromatograph equipped with a KC1
    flame thermionic detector.

PROCEDURES FOR DETERMINATION OF PESTICIDE RESIDUES




                IN BOTTOM MUD SEDIMENTS
                         60

                           Appendix VI

Procedures for Determining Pesticide Residues in River Bottom Sediment
and Mud
General;

Same general considerations on cleaning of glassware and distillation of
solvents as for previous procedures.  Recovery studies are also required to
determine the efficiency of the procedures.

Representative samples of mud and sediment should be dried to determine the
dry weight for calculation.  The following procedures, however, utilize the
wet mud or sediment after drainage of the excess water.

Calculations are the same as outlined for water samples after determining
the dry weight of the sediment.

A.  The Analysis for Organochlorine and Organophosphate Insecticide Residues.

    Procedure 1:  Organochlorine insecticide residues

    1.  Place 50 grams of mud sample in a Waring Blendor and add 300 ml
        of glass distilled acetone.  Blend the contents at slow speed for
        5 minutes at the 30 volt setting on the Variac Voltage Regulator.

    2.  Filter the blended solution through Whatman No. 1 filter paper in
        a large conical funnel.  Cover the funnel and collecting vessel to
        minimize evaporation.  Measure the filtrate collected.

    3.  Place a 150 ml aliquot of the filtrate in a 1-liter (teflon stopcock
        and stopper) separatory funnel and add 500 ml of 2% Na^SO,.  Shake
        the contents of the funnel to mix thoroughly  (venting as Required).

    4.  Extract the aqueous phase in the separatory funnel with 200 ml of
        glass distilled petroleum ether by vigorous shaking for 1-2 minutes
        (vent funnel as required).  Separate the phases collecting the
        petroleum ether in a second 1-liter separatory funnel.  Re-extract
        the aqueous phase with an additional 100 ml of petroleum ether,
        separate and combine the organic solvent phase with the first ex-
        traction.

    5.  Wash the petroleum ether extract by shaking with 100 ml of 2%
        NaHCOo and then transfer the extract to a 500 ml round bottom eva-
        poration flask.  Concentrate the extract to an appropriate volume
        with a rotating flash evaporator (water temperature not exceeding
        40° C) and then proceed with the florisil or  fiordsil-silica gel
        clean-up and gas chromatographic analysis indicated for analysis
        of water samples.
                                61

-------
Note:  If the background is too great for accurate gas chromatographic
analysis, additional clean-up will be required.
Procedure 2:  Organophosphate insecticide residues

1.  Place 100 g of soil in the Waring Blendor and 400 ml of glass dis-
    tilled acetone.  Blend the material and filter as indicated in
    Procedure 1 above.

2.  Place a 200 ml aliquot of extract in the 1-liter separatory funnel
    with 500 ml of 2% Na2SO, and extract with petroleum ether as outlined
    above.

3.  Wash the combined petroleum ether with 500 ml of 2% Na2SO^, transfer
    to a round bottom evaporation flask and after concentrating the
    solution to an appropriate volume inject aliquots on the gas chromato-
    graph equipped with the thermionic detector.


Procedure 3:  Organophosphate insecticide residues (when additional clean-
              up is necessary)

1.  Follow the same procedure as outlined above to and including the
    concentrating of volume by rotary flash evaporation.  Then follow
    the column clean-up procedure as outlined previously for organophos-
    phate residue in water samples using florisil and silica gel.

2.  Wash the column with petroleum ether and then elute with 250 ml of
    glass distilled benzene (contains organochlorines) followed by 200
    ml of 10% ethyl acetate in benzene (contains the organophosphates).

3.  Concentrate the separate eluates with the flash evaporator and inject
    aliquots of the organochlorine extract on the gas chromatograph
    equipped with electron capture detection and the Organophosphate
    extract on the gas chromatograph equipped with thermionic detection.

Procedure 3 utilizes  the sample extraction, etc. of Procedure 2 above
and is used for simultaneous determination and  the procedures outlined
for simultaneous analysis in water samples.


Note:  These procedures will not always provide adequate clean-up of
some  extremely dirty  samples.  Additional clean-up may be  required, parti-
cularly for organochlorine  residue determination.  The use of a Sweep
Co-Distillation Apparatus at 180° - 185° C oven temperature, Storherr
columns packed with silanized  glass wool and the mini-scrubber column of
anachrom will provide as good  if not better clean-up of extracts  for
analysis  of organophosphates by theriomic detection as will the  florisil-
silica gel  column  clean-up.
                                  62

-------
B.  Analysis for Chlorophenoxy Acid Herbicide Residues (2,4-D; 2,4,5-T;
    Dicamba; etc.)  (See procedure for analysis of water)

    1.  Fifty grams of sample is blended with 500 ml of 2% NaHC03 + 0.125%
        EDTA solution in the Waring Blendor for 5 minutes and the solution
        filtered as outlined previously.

    2.  The volume of solution is measured and recorded and the entire sample
        extracted in a 1-liter separatory funnel with 200 ml of glass dis-
        tilled benzene.

    3.  After discarding the benzene add 100 ml of 3.0 N H2SO,(pH of aqueous
        phase now -  1.0) and extract with 200 ml of benzene as outlined for
        the water analysis.

    4.  An emulsion forms in the above extraction.  After phases separate as
        much as possible, separate and discard the aqueous phase and transfer
        the emulsion to 250 ml centrifuge bottles.  Balance the weight and
        centrifuge  at 2000 rpm for 20 minutes (If bottles break,the speed
        of the centrifugation will need to be reduced appropriately.

    5.  Separate the organic phase and proceed with the evaporation (HCL
        washed glassware), methylation, clean-up and measurement as outlined
        previously for water analysis.


C.  Analysis for Triazine Herbicides

    1.  Blend 100 g of sample in a Waring Blendor (slow speed) with 400 ml
        of acetone for 3 minutes.  Then add 125 ml of distilled water and
        blend for another 3 minutes.

    2.  Filter the solution through Whatman No. 1 filter paper and collect
        in a 16 oz. bottle.  Take care to avoid excessive evaporation.

    3.  Transfer 1/2 of the total extract to a 1-liter separatory funnel,
        add 500 ml of 2% ^280^ and extract by vigorous shaking with 250 ml
        of glass distilled benzene.

    4.  Backwash the benzene twice with 500 ml aliquots of 2% NaHCOg and
        then evaporate the benzene extract to approximately 5 ml volume.

    5.  Prepare a 20 x 350 mm reservoired column containing from top to
        bottom 1 inch anhydrous Na2SO/, 15 gram (Approx. 2-1/2 - 3 inches of
        polyethylene coated alumina (Kensington Corp.), and 15 g (2-1/2 -3
        inches) of Aluminum Oxide - Woelm Act Grade IV.

    6.  Place the extract on the column.  Wash the material on the column
        with 200 ml of petroleum ether.  Then elute the triazines from the
        column with 250 ml of NH3 saturated benzene.
                                 63

-------
7. Concentrate the eluate to an appropriate volume and inject
   aliquots on the gas chromatograph equipped with thermionic
   detection.   (Note:  Too much background due to inadequate
   clean-up reduces sensitivity on the capture detector.

8. Follow detection and calculation procedures as outlined for
   analysis of water samples.
