PREFACE
This research grant was funded to improve and extend a non-point sources
research program previously funded by NSF/RANN from 1973 to December 1976 and
by the Environmental Protection Agency since that time. The study site is the
Rhode River, a tidal arm of Chesapeake Bay, and its watershed. It is located
in the Maryland coastal plain on the western shore of Chesapeake Bay in an
area which is primarily agricultural.
The purposes of the grant included (1) the measurement of the relationship
of pollution with herbicides, nutrients, sediments, heavy metals, and bacteria
to agricultural land uses; and (2) the collection of data for the testing of
field and basin-sized watershed models.
This grant was initiated on June 14, 1976, but has profited from the
prior existence of a large data bank and some research conducted "in anticipa-
tion" of the award of the grant to obtain 'baseline' data in the early spring
before crops v/ere planted.
The grant was also amended to include a study of the effects of agricul-
tural land runoff on submerged, rooted aquatic plants in Chesapeake Bay. The
funds for this amendment came from EPA region Ill's Chesapeake Bay Program.
The purposes of this amendment included (1) the field testing of two hypotheses
of the causes of plant die-offs in recent years - agricultural herbicides and/
or increased shading due to sediments and phytoplankton; and (2) laboratory
bioassay studies of herbicide effects on rooted aquatics.

ABSTRACT
The research program was initiated in April, 1976 (to obtain baseline
data before crop planting) and full-scale activity (funded) began in June.
Data on herbicide and fertilizer application, soil chemistry, and the volume
and composition of runoff waters were obtained for a cornfield watershed for
a complete year. Rainfall, soil moisture and temperature, plant growth and
nutrient removal, soil coverage by plants, soil erosion rates, soil mineral-
ogy and particle size distribution were also monitored. A woodlot watershed
has also now been instrumented. Data on the volume and composition of runoff
from this second field-sized watershed are also being gathered,, as well as
soil temperature, moisture, and compositional data. Runoff samples from eight
basin-sized watersheds and rainfall composition were also analyzed for cation
and herbicide concentrations. A site for a pasture watershed has been selected
and a weir has been constructed. Instrumentation of the weir and soil stations
are under way. Some water quality data have been collected. A total of six
fraction collectors have been constructed and a suspended sediment splitter
was designed and built. An improved rainfall gauging network has been
instrumented including seven recording and 20 manual gauges. A freezer, an
explosion proof refrigerator, and a walk-in cold room have been purchased and
installed. A Tracer gas chromatograph with both (E-C and Hall detectors was
purchased and is now operational. Improved areas for well ventilated solvent
extraction and concentration have been provided for herbicide extraction.
Surveys of farmer and homeowner land use practices have been carried out.
Sampling and measurement of herbicide concentrations in estuarine waters,
suspended sediments, and bottom sediments, turbidity, suspended sediment load
and phytoplankton chlorophyll concentrations, bottom sediment characteristics,
iv
-------
salinity, and submerged, rooted aquatic plant populations was carried out
monthly at five stations in the Rhode River estuary, four times a year at
eight stations in the Choptank River estuary, and at four stations in the
shallows near the Poplar Islands in the open areas of Chesapeake Bay.
Beginning in the spring of 1977, weekly studies were conducted at one Rhode
River station including in situ bioassays of respiration and photosynthetic
rates of the plants.
The first set of laboratory bioassays under controlled conditions has been
completed. Zanriichellia palustris (Horned pondweed) was grown in aquaria
under controlled conditions selected to simulate conditions prevalent at the
Rhode River station which is assayed weekly. Moncontaminated forest soils
• were used for bottom sediments. Linuron and atrazine toxicity were separately
studied in a total of 16 tanks. Plant responses measured included weight gain,
growth in length of leaves, photosynthetic rates, and respiratory rates. These
parameters were measured at eight time points over a time span of four weeks.
All samples taken prior to May 1977 have been analyzed for all parameters
with the major exception of cations and herbicides. Many soil and
estuarine bottom sediment samples have not yet been analyzed for herbicides
and, while all runoff samples have been processed and prepared for cation
analysis, the atomic absorption assays are not completed. Some of the acquired
data has not yet been computer processed and not very much detailed data
analysis and summarization has been completed.
This report was submitted as the first annual progress report on research
Grant No. R804536-01 by the Smithsonian Institution's Chesapeake Bay Center
for Environmental Studies under the partial sponsorship of the U. S. Environ-
mental Protection Agency. This report covers the work done during the period
April 1976 to June 1977.

INTRODUCTION
This is the first annual progress report on this grant. It is both a
status report and a detailed data report. It is not an in-depth analysis of
results. It does include information with respect to an amendment to this
grant entitled "The Relationship Between Die-Off of Submerged Higher Aquatic
Plants in Chesapeake Bay and Herbicides in Land Runoff", which was funded by
Region III of Environmental Protection Agency. Some prior work on this aspect
of the research program was funded in June and July, 1976 under Contract WD-6-
99-0766-J from Region III (Correll, Wu, and Pierce; 1976).
The watershed research part of this grant was focused, for the first year,
upon:
(1) The selection and instrumentation of three field-sized watersheds
with predominantly one land use. These were row crops(corn), pasture!and, and
forest.
(2) The measurement of a restricted set of parameters (herbicides, cations)
on runoff from eight previously instrumented basin-sized watersheds and of a
much more detailed set of watershed and runoff parameters from the three field-
sized watersheds.
The research in the above amendment was focused upon testing two hypotheses
of the causes for a general die-off of rooted, submerged aquatic plants in
Chesapeake Bay in recent years. These hypotheses were:
(1) That the plants are being inhibited or killed by agricultural
herbicides in land runoff, and
(2) That increased turbidity due to erosion and increased phytoplankton
blooms are shading out the rooted plants.
-------
These two hypotheses need not be mutually exclusive since both agri-
cultural herbicides and reduced light penetration would reduce photosynthesis
(many of the herbicides are photosynthetic inhibitors).
The watershed program'at Rhode River
The Chesapeake Bay Center for Environmental Studies, established in 1965
by the Smithsonian Institution, is a 1,000 hectare research facility on the
Rhode River. Rhode River is a subestuary on the western shore of Chesapeake
Bay just south of Annapolis, Maryland, This site was chosen for long-term
environmental research because it offered the opportunity to study an estuary
and its associated watershed which had many desirable features for an intensive
study. The system is small enough (485 ha of open water and 3,332 ha of
watershed) to be studied in some detail, yet large enough to have most of the
characteristics of an estuary and multiple land use watershed typical of the
coastal plain on the western shore of Chesapeake Bay. A large part of the
research program at the Center is concerned with man's effect on the watershed
through air pollution, land use practices, and the changing pattern of land
brought about by a rapidly growing human population.
The goals of the watershed program include:
(1) The accurate measurement of the loading of the estuarine receiving
waters with land runoff waters and the contents of the runoff waters.
(2) The determination of the present average area yield loading rates
for each major land use category on the watershed for each parameter. This
will enable accurate predictions of the effects of urbanization, etc. on
diffuse source estuarine loading to be made by a deterministic approach.
(3) The determination of sufficiently detailed information on watershed
characteristics, local meterology and runoff parameters from small single-use
2
-------
watersheds, typical of each major land use category to allow the development
of mechanistic predictive models.
(4) The determination of the effects of variations in land use practices
upon runoff from each major land use category.
(5) Testing the results and predictions derived from studies of the Rhode
River watershed for their validity or transferafaility on other coastal plain
watersheds in this region.
(6) To develop a tested methodology for application in other regions.
These goals point out the extent to which this program is focused upon the
impact of man's activities upon the watershed. The watershed was settled by
Europeans in the 1650's and cleared for agriculture. Prior to that time, it
was occupied intermittently by Indian villages for several thousand years. It
should be noted that this watershed had a human population of about 3,000 in
1973, and in 1976 the portion of the watershed under study (2,964 ha) had a
land use composition as follows: 15.8% row crops; 2.2% freshwater (nontidal)
swamps and ponds; 1.9% tidal marshes; 58.6% forest and old fields; 10.2%
pasture; and 11.2% residential, commercial, and other categories. A land use
history based upon written records has been compiled by Dan Higman and an oral
land use history is being compiled by Amy Hiatt. The spatial pattern of land
use on the watershed can best be described as a mosaic, and is typical of this
region. Thus, it is not possible to select subwatershed basins of any size
(more than a few ha) which contain only one land use. Instead, basins contain-
ing a more complex mixture of land uses must be studied and the results
analyzed with respect to the effects of land use.
-------
Description of watershed
The geography of the Rhode River watershed and the various subwatersheds
which are under study are shown in Figure 2. The location of the weather
station (W) and rain gauges (R) are also shown. Table 1 lists the subwater-
sheds under study by name and number, as well as giving their total surface
areas and a summary of the proportions of six land use categories present on
each. The monitored watersheds vary in size from a few hectares to about 1,200
hectares. Land use varies from all or nearly all one type to complex mixtures
of all land use categories. The larger basins include some (102, 108) with
relatively high proportions of row crops, one (121) with more upland wet areas,
one (122) with more tidal wet areas, many (103, 105, 107, and 122) with high
proportions of forest and old fields, some (101, 106) with more pasture, and
two (123, 124) with more residential area. Small single-use watersheds (109,
110, 111) have been selected for intensive study of areas which best typify
row crops, forest, and pasture land uses. The slopes of the larger watersheds
average between 3 and 9 percent with an overall average slope for the whole
study area of about 5 percent. Geologically the Rhode River watershed has
sedimentary soils from the Pleistocene Talbot formation at low elevations on
the eastern portion of the watershed and Eocene Nanjemoy formation soils at
low elevations further west, Miocene Calvert formation soils at intermediate
elevations and Pleistocene Sunderland formation soils at the highest elevations.
A few outcrops of Pleistocene Wicomico formation soils are also found. The
mineralogy of the soils in the various parts of the watershed is fairly
uniform with a high level of montmorillonite and quartz, intermediate levels
of illite and kaolinite, and low levels of gibbsite, chlorite, potassium
feldspar, and plagioclase. The soils differ locally primarily with respect to
the proportions present of sand, silt, and clay. Bedrock is several thousand
4
-------
feet below the surface. The aquaclude is a clay layer, the Marlboro clay
at about sea level elevation throughout the watershed.
Scope of the research
The Rhode River watershed research program began in the summer of 1971.
At that time the monitoring of water composition in five streams was begun.
Also, Dr. Edward Pluhowski, of the U. S. Geological Survey built a 90° notch
weir on watershed 101 and began to establish a rough correlation between
stream flow on each of the other four streams and the flow he measured at
station 101. The composition of grab samples from these streams was measured
until it became apparent in 1973 that permanent weirs and volume-integrated
composite sampling on each watershed would be necessary to accurately measure
discharge rates. By early 1974, the first five of these weirs were completed.
The network of weirs has been enlarged to 11 permanent and 2 temporary weirs
in operation at the beginning of 1977. Six more permanent stations are under
construction or planned for 1977. These monitoring stations are of two general
types but all are designed to measure the volume of water movement and to
sample proportional to that flow. In addition to composite samplers, six
fraction collectors for the discrete sampling of storm events have been built.
Special rainfall collectors for rainfall and dryfall chemistry were first
used in early 1973.- Now several types are in use. They are located at the
weather station in Figure 2. A network of rain gauges was established in 1973.
One has been operated at the weather station for many years. The weather
station, operated by Dan Higman, measures sunlight, rainfall, evaporation,
wind speed and direction, air temperature, dew point, and barometric pressure.
Rainwater and stream water samples are now analyzed for: pH, turbidity,
temperature, total and orthophosphate phosphorus in filtered and whole water,
5
-------
total Kjeldahl nitrogen, nitrate, nitrite, ammonia, organic matter, alkalinity,
total and mineral suspended participates, suspended particle mineralogy, eleven
cations (Ca, Mg, K, Fe, Ni, Cu, Zn, Pb, Cr, Cd, Mn), total viable bacterial
cells, total and fecal coliform bacteria, fecal Streptococci, and six herbicides
(alachlor, atrazine, simazine, linuron, trifluralin, and paraquat).
Land use is determined by the analysis of low elevation aerial photos and
ground truth surveys. Land use practices of landowners are surveyed by the use
of door to door questionnaires. The land use practices surveyed include area
planted in each crop, applications of agricultural chemicals (e.g. herbicides,
fertilizers, lime), livestock populations, residential use of pesticides,
fertilizers and lime, and human populations.
In the case of field-sized watersheds, selected to typify major land use
categories, a number of parameters are measured to enable a better assessment
of the mechanisms or causes of changes in the composition of runoff waters.
These include detailed studies of land use practices, plant populations,
productivity, soil cover, frequent surveys of soil chemistry (e.g. levels of
various forms of nitrogen and phosphorus, levels of pesticides, pH, major
cations such as Ca, Mg, and K), detailed geochemistry (e.g. percentage of
organic matter, sand, silt and clay; mineralogy of silt and of clay), frequent
monitoring of soil temperature and moisture. The soil parameters are usually
determined as vertical profiles at each of a series of elevational contours.
Submerged aquatic plants research program
Dense beds of a number of species of higher plants formerly occurred
widely in Chesapeake Bay as submerged 'seagrass1 or 'seaweed' beds ten to
twenty years ago. These plant beds have suffered great declines, especially
in the last few years. The populations of many valuable animal species are
-------
now suspected to be, in turn, adversely affected by this vegetat.ional decline.
For example, Canvasback ducks depend heavily upon Potamogeton pectinatus (sago
pondweed) for forage and the 'seaweed' beds provide 'nursery grounds' for many
shellfish and finfish species. The dense beds of plants acted (1) to stabilize
the bottom sediments and (2) as wave filters to protect shorelines on the Bay,
thus their decline has been speculatively linked to increased rates of shore-
line erosion in recent years. The plant beds also function not only as primary
producers, but also as a mechanism of nutrient recycling from bottom sediments.
At least three speculative hypotheses have been advanced to help explain the
decline of higher aquatics in the Bay.
The first hypothesis is plant diseases. In one case, the so-called north-
east disease of milfoil, a specific virus has been shown to be involved in the
decline. However, many species of plants in several families are involved and
no strong evidence is available linking general plant population declines to
diseases.
The second hypothesis is increased turbidity due to both erosion and
phytoplankton, and consequent shading out of submerged plant beds. There is
some support for the contention that turbidity due to phytoplankton has increased
in the upper Bay in the last ten to twenty years (chlorophyll levels have gone
up significantly). Erosion has also been high in areas adjacent to housing
and industrial land developments. However, the evidence is not very compelling
that this is 'the major1 causal mechanism for the plant decline. Erosion has
not increased in many localities on the Bay where plants have died out and the
effects of erosion are rather localized.
The third hypothesis is that increased levels, as well as new types of
herbicides, used on agricultural lands in Maryland are the cause of the plant
die-offs. The list of herbicides which have been introduced on a wide scale
7
-------
in Maryland agriculture in the last twenty years as a partial or complete
substitute for mechanical crop cultivation includes simazine, atrazine,
linuron, alachlor, trifluralin, and paraquat. These compounds are generally
toxic to the 'seaweed1 or 'seagrass' plants, since they are vascular plants.
In fact, when these plants were abundant on the bay, atrazine and simazine
were used in their control. Some of this list of compounds are of special
interest, since they are more likely to be transported into the estuary
(linuron) or they are likely to be relatively persistent (simazine and atrazine).
Fieldwork
This research program was designed to experimentally approach the question
of whether any of these herbicides is, in fact, responsible for part of the
dramatic die-off of submerged aquatic plants in recent times. Much of the field
research is being carried out in the Rhode River, a subestuary of Chesapeake
Bay near Annapolis, Maryland. The Rhode River estuary has a surface area of
about two square miles of open water. The discharge of runoff water from most
of its watershed into the Rhode River is currently being monitored and sampled
for chemical analyses as part of the watershed research program. Less intensive,
but more extensive field research is being conducted on the Choptank River, a
large eastern shore subestuary of Chesapeake Bay, and at the Poplar Islands
(on the open bay). The watershed of the Choptank River supports relatively
intensive no-till agriculture while the crops on the Rhode River watershed are
primarily grown with minimum-till practices. No agriculture is practiced on
or immediately adjacent to the Poplar Islands.
Laboratory work
Bioassays of the effects of the herbicides most abundant in the bay on
important species of rooted, submerged higher aquatic plants are being conducted
8
-------
in the laboratory under controlled conditions. This is being done to test
whether herbicide concentrations encountered in Chesapeake Bay can be shown
directly, to be toxic to the plants.

CONCLUSIONS
After one year of funded activity, we feel that our non-point source
pollution research and estuarine plant/herbicide research program is pro-
ceeding well. Our initial intensive effort to measure the application of
herbicides and fertilizer to a cornfield watershed, as well as enough
parameters during the growing season and prior to planting to calculate a
mass-balance for these components has succeeded. A backlog of frozen,
stored samples is being analyzed for herbicides and no final results can be
reported yet, but no serious sampling or analysis omissions have been found
and the research is flowing smoothly as planned. The construction and
instrumentation of a cornfield watershed weir, a woodlot watershed weir,
and a pasture watershed weir have been completed. Samples from previously
existent basin-sized watershed weirs are being analyzed routinely for cations
and herbicides. Landowner chemical application data is being collected by
door to door survey. Estuarine data on plant populations, habitat factors,
shading factors, and herbicide factors.is being collected. Plant bioassays
in the laboratory are ongoing. Data from all phases of the program are being
processed and stored on a computer data bank. We have no reason to suspect
that our original two year work projections and time schedules cannot be met.

RECOMMENDATIONS
I. Watershed Research Program
As a result of our research efforts to-date several recommendations can
be made to improve future results.
1. More emphasis should be placed on shallow ground water hydrology.
a. Ground water wells for the measurement of water table slopes,
percolation rates and ground water composition would be very helpful.
b. A neutron probe would provide much better soil moisture data for
hydrological purposes.
c. Some exploration of stratigraphy to establish the aquae!ude for
these watersheds would be very useful.
2. A much closer interaction with the people involved in watershed
modeling for EPA would be desirable.
3. The use of an apparatus to measure the light scattering due to
particulates in unprocessed water samples, such as a ruby layer system
marketed by Spectrex, would be valuable in the determination of the
degree of aggregation and flocculation of suspended particulates.
II. • Estuarine Plant Die-Off Program
As a result of this research study, a series of recommendations can now
be made with respect to further resolving and defining, in an objective
quantitative way, the causes of the observed die-off of submerged higher
aquatic plants in Chesapeake Bay. Also some recommendations can be made with
respect to other ramifications of our findings.
1. Data on the concentrations of other commonly used herbicides,
especially paraquat and the phenoxyacetic acids should be collected.
11
-------
2. Bioassays of chronic toxicity to filter-feeding shellfish and their
larvae such as oysters should be run by varying the concentrations of
herbicides in suspended particulates.
3. Attempts should be made to identify and quantitate principal
degradation products of such herbicides as atrazine and to test their
toxicity.
4. A sediment seed-bank study should be carried out in Chesapeake Bay
to establish the come back potential of the rooted, submerged higher
aquatic plant species native to the Bay.
5. Bioassays of synergistic herbicide effects on submerged, rooted
aquatic plants should be initiated.
6. Bioassays of the toxicity to submerged, rooted aquatic plants of
potential replacement herbicides for preemergent applications on soybeans
and corn should be initiated.
7. Bioassays of the toxicity of paraquat on submerged, rooted aquatic
plants should be carried out to test whether this herbicide is toxic to
the plants after it binds to clays and particulate organic matter.

METHODS
I. Land Use Survey
1. Farm land use
Using the 1972 tax map as a guide (with some revisions) we have
identified 53 farms in the Rhode River watershed. These lands cover
about 6648 acres or about 74% of the watershed. For the purposes of
this survey we have defined a "farm" as any individual parcel (or
combination of adjacent parcels with the same owner) which consists of
20 acres or more. Only about 60% of these "farms" contain any land that
is actually being used for the production of crops, so the term is some-
thing of a misnomer. The remaining lands fall under a variety of land
use categories: woodland, recreational, abandoned fields, etc. Since
almost all real farms also contain some of these other land uses we saw
no reason to limit the sample.
So far we have surveyed all of the farms in the watersheds covered
in this report. Detailed data on livestock, land use ground truth for
each field, fertilizers, lime, and pesticides have been compiled. Where
advisable the amounts and identity of farm chemicals have been further
confirmed at the local farm cooperatives, where most local farmers obtain
their materials.
2. Residential land use practices
A retired door-to-door salesman who lives on the watershed, was hired
part-time to conduct this survey. A questionnaire was designed to put
the home owners at ease by asking such questions as how do you keep your
lawn so good looking? The residential parts of the watershed were first
divided into neighborhoods whose boundaries correspond to both drainage
13
-------
basins and neighborhood age, affluence, etc. Then each was subjected to
a stratified random subsampling of about 20% of the homes and businesses.
3. Land use on field-sized watersheds
a. Herbicide application on cornfield 109
Herbicides are applied (by a tractor-drawn sprayer) to the corn
fields in the normal manner recommended by U.S.D.A. and the manufac-
turers. The more commonly used herbicides that are recommended by
the state of Maryland on corn fields are atrazine, simazine, alachlor,
and paraquat. In order to accurately measure the dose per surface
area of applied herbicides, the rate of spray application is measured
in three ways: (1) the time of application is measured per whole
field and volume of spray per time is measured under actual field
conditions; (2) 142 mm Whatman #42 filter paper discs are placed flat
on the field prior to spraying at ten stations and later analyzed for
pesticide; (3) large volume soil cores are taken for 0 - 1 cm
segments. Samples of spray and the filters and soil samples are then
analyzed in the laboratory.
b. Fertilizer application on cornfield 109
Times and application rates and methods are noted from observation,
consultation with the farmer and manufacturer's labels, actual samples
of granular and liquid fertilizer are also laboratory analyzed. Spray
application rates are also measured as above (part a).
c. Other land use data on 109 and 111
Lime application rates are calculated from farmer data and times
of application are noted. Cultivation times and methods are noted
for 109. Dates and populations of cattle on 111 are recorded
routinely. The dates and yields of hay mowing for 111 are recorded.
14
-------
Dates and yields of corn harvest from 109 are also recorded. Any
other farm management practices are also noted.
II. Soil Analysis
1. Sampling
Soils are sampled as needed for the purposes of the pesticide and
nutrient transport models with a split tube soil coring tube and/or a
large volume shallow coring apparatus (as developed by Charles Smith,
Athens, Georgia, EPA). Sets of integrated soil samples are taken at
specified intervals by taking three cores at each of ten stations on
*
each watershed, segmenting them, and combining segments (one from each
core) from like depths at each location and in some cases from stations
on the same elevatfonal contour line (Correll and Miklas, 1975).
Stations are placed along elevation contours. Cores have been divided
into segments; 0 - 1 cm, 1 - 2.5 cm, 2.5 - 5 cm, 5 - 8 cm, 8 - 12 cm,
18-24 cm, and 24 - 30 cm. These segment dimensions may change as model
requirements are defined. Composite soil samples are then homogenized
with a twin-shelled blender. Sampling frequency varies from daily (for
herbicides) immediately after application of chemicals to seasonal.
Soil samples are kept frozen until they can be analyzed.
2. Temperature and moisture
At each soil sampling station moisture and temperature probes
v/ere buried at depths of 5, 15, 30, and 75 cm with electrical leads
connected to sockets in a junction box aboveground for manual readings.
Delmhorst gypsum block moisture sensors and a Delmhorst, Model KS-1,
moisture testor are used. The ranges of the tester have been modified
to allow zeroing against 0, 100, or 10,000 ohms resistance. In situ
calibration curves for each probe were constructed by gravimetric
15
-------
moisture determinations from soil cores at the appropriate depths under
various moisture conditions. Temperature was measured with Fenwal preci-
sion unicurve thermistors, coated with epoxy cement and resistance was
read with a battery powered Fluke digital multimeter. During intensive
study periods reading of probes are made daily. At other times they are
read approximately weekly.
3. Percent sand, silt, and clay, organic matter; mineralogy
Soils are fractionated into sand, silt, and clay by screening and
hydrodynamic methods and each fraction is weighed. The amount of organics
is determined by firing. Mineralogy is determined on silt and clay
fractions by X-ray diffraction. Preparation is described by Carroll
(1970). Soils are analyzed for free-iron oxides and allophane (Jackson,
1956).
4. pH
pH was measured with a hydrogen electrode system after suspension of
an aliquot of soil core in one ml of distilled water per g of soil and
centrifugation.
5. Cations
A sample of 0.1 g of oven-dried soil is placed into a 30 ml micro-
Kjeldahl flask. 5 ml of concentrated nitric acid is added and boiled
gently until the solution is about 2 ml, cool the Kjeldahl flask and add
10 ml of distilled water and again boil down to about 2 ml. The solution
is then diluted to 50 ml with distilled water in a volumetric flask.
Aliquots of this solution are subjected to atomic absorption analysis for
Fe, Mn, Zn, Ni, Cu, Cd, Pb, Cr, K, Ca, and Mg. A Jarrell Ash 82-500
atomic absorption spectrophotometer was used. Concentrations reported
are corrected for efficiency of analysis.
16
-------
6. Herbicides
a. Extraction
To a glass thimble which contains approximately 3 g of anhydrous
sodium sulfate an accurately weighed wet soil sample of 10 g is added.
Then add another 3 g of anhydrous sodium sulfate on top of the soil
sample. This thimble is subjected to a soxhlet extraction with a
mixture of 50 ml benzene and 150 ml of methylene chloride. Water
content of the soil is determined by drying a duplicate sample of
0.20 g wet soil at 100° C for 24 hours.
b. Clean-up procedure
The organic extract is treated overnight with anhydrous sodium
sulfate and is then concentrated to about 8 ml with a Kuderna-Danish
Evaporator on a water bath, a glass chromatographic column packed
with 15 g of alumina (activity grade V) and topped with 5 g anhydrous
sodium sulfate, is washed with 50 ml petroleum ether. The sample is
applied to the column and eluted with 100 ml hexane and then a mixture
of 50 ml bezene and 50 ml hexane. The combined elute is then con-
centrated to about 8 ml and stored in a refrigerated glass tube.
c. GLC chromatography
A 2yl sample of a cleaned-up sample is injected into a Packard,
model 802, gas chromatograph equipped with a tritium electron capture
detector, or a Tracor, model 560, gas chromatograph equipped with a
Hall, model 310, detector and a Ni 63 E-C detector. A 6 ft X 4 mm
coiled all glass column is used. The column is packed with 10% DC
200 on Gas-chrom Q (80-100 mesh). Input temperature is 190°, column
temperature is 165°, detector temperature is 200°, and outlet
17
-------
temperature is 190°. Standard herbicides are run between each
unknown sample and the next. Calibration series are run with
standard solutions of each herbicide.
d. Confirmation of GC peaks
It is necessary to confirm the identity of various peaks
occasionally. We plan to do this in two ways.
First, we plan to confirm by subjection of samples to integrated
GC/mass spectrograph analysis. This confirmation work is to be done
by Dr. Edward Oswald in the Analytical Chemistry Laboratory of the
EPA facility at Research Triangle Park, North Carolina.
Secondly, we make confirmations by the two column procedure. A
second GC column (Carbowax 20 M) is run (Muir and Baker, 1976).
7. Nutrients
a. Nitrogen
i. Total Kjeldahl nitrogen is determined by digestion with
sulfuric acid and hydrogen peroxide, distillation and
Nesslerization (Martin, 1972).
ii. Total ammonia is determined by Kjeldahl distillation from
undigested but alkaline samples plus Nesslerization.
iii. Water soluble ammonia is determined as above but on
distilled water extracts of soil
iv. Exchangeable ammonia is determined on 1 M K Cl extracts of
previously water extracted soils.
v. Nitrate is determined by the modified Conway microdiffusion
method Stanford, et al (1973).
18
-------
b. Phosphorus
Total phosphorus, acid labile, and orthophosphate were determined
as described by Correll and Miklas (1974). Total phosphorus was
determined on whole soil only. Orthophosphate was determined on
whole soil, a 1 M K Cl extract, and on a distilled water extract. The
extraction procedure is to extract one gram of soil with 15 ml
distilled water, then with 10 ml distilled water, removing soil from
extraction liquid by centrifugation. The extracted soil is then
reextracted in the same manner but with 1 M K Cl.
III. Meteorological Measurements
1. Rainfall and dry fall
Tilting bucket rain gauges (Stevens) with a resolution of 0.01 inch
per pulse and a readout on paper tape every five minutes are located at
six stations (Figure 6). A strip chart recording weighing rain gauge is
also located at the weather station (Figure 2). A total of 20 manual
rain gauges are now located on the watershed (Figure 6). Rainfall is
also collected in a special apparatus mounted 13 meters above the ground
for chemical analysis (nutrients and heavy metals). The rain collectors
consists of two identical four liter pyrex glass bottles, and two
Nalgene polyethylene 28 cm diameter funnels. The funnels are fitted to
the top of the bottles with a rubber stopper. Fiberglass window screen-
ing was placed over the funnels to prevent insects from getting into the
bottles. Both funnels were exposed to atmospheric fall out at all times.
One funnel was used for bulk precipitation measurements, the other was
used for dry fal1.
19
-------
Bulk precipitation samples were taken continuously. The sampler
was emptied after each rain event and then repositioned. If sufficient
sample was taken from one rain event, it was then analyzed. If the
rainfall amount was too small, it was placed in a sealed plastic bottle
and refrigerated at 4° C until the next bulk precipitation sample was
added to it. This procedure went on until sufficient sample was obtained.
The bulk precipitation collector bottle funnel and screen were cleaned,
and dates and times recorded each time a sample was removed. This
procedure assumes that each rain event washes the dry fall off the funnel
into the bulk precipitation collector bottle. Thirty-three bulk
precipitation sampling events were analyzed for 1976. The exposure time
ranged from one day to twenty-eight days. Elemental loading rates in
Kg/ha-day were determined for each bulk precipitation sampling event.
This data was then cumulated into monthly, seasonal, and yearly values.
Dry fall samples were taken intermittently. If a rain event occurred
while the sampler was in position, the sample was discarded. Each time
a sample was taken or discarded, the entire sampler was cleaned, then
it was repositioned, and the dates and times were recorded. If no rain
event occurred during sampling time, a liter of distilled water was used
to wash the dry fall off the funnel into the collector bottle. The
sample was then analyzed for the five elements. Exposure time ranged from
two to six days and the mean time was 2.9 days. One hundred thirteen
days of dry fall data were analyzed in 39 separate sampling events for
1976. Naturally more samples were taken in dry months than wet months.
Exposure time, surface area of the funnel, and concentration were all
used in determining the loading rate in Kg/ha-day. This loading rate
was determined for each dry fall sampling event. Time points between
20
-------
sampling events were given mean loading rate values as determined by
averaging the loading rates determined immediately before and after the
missing time interval. Loading rates were then cumulated for the entire
month and were then adjusted by subtraction of a fraction equal to the
proportion of the time when rain was falling. These adjusted monthly
values were cumulated into seasonal and yearly values, and expressed as
percent of bulk precipitation.
Another large surface area stainless steel apparatus is located at
the Center on a roof top for the collection of rainfall for pesticide
analysis.
2. Evaporation and wind run
These parameters are monitored with automated standard weather
equipment (evaporation pan and anemometer).
3. Air temperature, dew point, wind speed and direction, and sunlight
These parameters are monitored with automated thermister, Lithium
chloride sleeve dew point apparatus, anemometer and weathervane {at
elevation of 20 meters), and an Eppley precision pyroheliometer.
IV. Plant Populations on Field-Sized Watersheds
1. Corn plant heights and soil coverage on watershed 109
Corn plant height and total plant soil coverage are measured in the
cornfield watershed at approximately 10 day intervals during the growth
season. Heights were measured at five stations on randomly selected
plants. Soil coverage was measured by taking vertical color pictures
from an elevation of 6 meters. Percent leaf coverage was estimated by
projecting the color slides onto a grid with randomly selected intercepts
premarked. The percentage of intercepts which fell on plants was then
used to calculate soil coverage (point-intercept method).
21
-------
2. Biomass and nutrient removal of corn on watershed 109
At approximately 20 day intervals during the growing season and at
harvest time corn plants were excavated at five stations. They were
separated into roots, stems, leaves, flowers, corn kernels, and corn cobs
for dry weight determinations, total Kjeldahl nitrogen content, and total
phosphorus determinations. Nutrient assays were done by the same
techniques as for soils. In September aboveground weed biomass was
P
measured as numbers and dry weight by species in three 25 m plots at
each of the ten stations. Three random 0.5 X 0.5 m subplots were
sampled.
3. Plant leaf area indexes
At approximately 20 day intervals during the growing season corn
leaf areas per plant were determined and in September weed leaf areas were
determined by species in the same plots used for biomass.
4. Plant populations on watershed 109 cornfields
In September the numbers of plants of each species on the cornfield
watershed were measured per surface area in the same plots used for
biomass and leaf area.
5. Plants on watershed 110
•j
Twenty 1 m wooden litter fall boxes, with screen bottoms, were
distributed over the entire watershed in a stratified random pattern.
Leaf, seed, and miscellaneous litter were collected at one or two week
intervals. These samples are sorted by species and counted. Regressions
of weight and leaf areas for each species are used to establish these
parameters based on data collected the two prior years.
22
-------
V. Runoff Waters
1. Hydrographs and water sampling
All weirs (Stations 101, 102, 103, 105, 106, 107, 108, 109, 110, 111
in Table 1) are now 120° sharp crested V-notch weirs. The instrumentation
of these weirs was described in Correll, Pierce, and Faust (1975). It
has now been improved to include two parallel sampling pumps one of which
pumps to a glass sample bottle, the other to a plastic sample bottle
which contains a small volume of 18 N sulfuric acid initially. In some
cases, on very small watersheds, the normal 25 lobe sampling cam in the
Leupold and Stevens Model 61 R flow meter has been replaced by a 50 lobe
cam. Custom fraction collectors have been built for use on some weirs,
especially on small single land use watersheds. These fraction collectors
are designed to trigger automatically at a predetermined water stage.
They then collect a fixed aliquot of water every time the flow meter
sampling switch is triggered (giving a pulse) by a given volume of flow.
A pulse counter triggers the fraction collector to move from one bottle
to the next when the preset number of pulses have been received, and an
event marker on the flow meter strip chart records the times of fraction
collector movement. Twelve bottles of twelve liters volume each can be
collected. Since the fractions-are collected at identical times to the
volume-integrated composite samples, the composition of flows prior and
subsequent to storm event flows can be calculated. All stations are
entirely battery operated and are usually serviced twice a week. Volume-
integrated samples are collected weekly.
Grab samples are also taken every two weeks at a recorded time and
discharge rate for analysis of non-conservative parameters. Samples from
storm events are split with a stainless steel water-sediment splitter
(Fleming and Leonard; 1973). Samples are refrigerated prior to analysis.
23
-------
2. Particulates
Samples of water from weirs are filtered and the concentrations of
total participates and mineral phase are then determined, as well as
size fractions and mineralogy. The volume-integrated composite samples are
filtered through pre-weighed and treated, 0.45 urn nominal pore size
filters to remove the particulates. Weight-gain of the filters gives
total particulate material, and loss of material upon combustion gives
a measure of organic material. Spot-samples at known flow rates will
be taken for mineralogy by X-ray diffraction and size distribution.
Mineralogy will be done on selected volume-integrated samples also.
(Carroll, 1970).
3. Cations
Samples for heavy metals determinations are prepared by concentration
of 500 ml of whole water to 10 ml after acidifying with 5 ml cone. HN03.
Samples are then diluted appropriately and assayed for Fe, Mn, Zn, Ni,
Cu, Cd, Pb, Cr, K, Ca, and Mg by atomic absorption.
4. Nutrients
Samples are analyzed for concentrations of (1) total and ortho-
phosphate before and after Millipore HA filtration, (2) nitrate plus
nitrite, (3) ammonia, (4) organic nitrogen, (5) total organic matter.
The techniques used are those in common practice for nonautomated wet
chemistry. These concentrations multiplied by the water discharge rates
give total discharges per watershed.
a. Particulate and dissolved ortho- and total phosphorus
Samples plus or minus Mi Hi pore HA filtration in the field are
analyzed for phosphate by the stannous chloride method (Standard
Methods, 1971) before and after digestion with perchloric acid
24
-------
(King, 1932). Composited samples are only analyzed for total
phosphorus.
b. Nitrate plus nitrite
Nitrate is converted to nitrite by passage through an amalgamated
cadmium column. Then nitrite is determined colorimetrically
(Standard Methods, 1971).
c. Ammonia
Determined by oxidation to nitrite with sodium hypochlorite and
then as above.
d. Organic matter
Determined by Kjeldahl digestion as described by Martin (1972),
distillation of the released ammonia and Nesslerization.
e. Organic matter in fresh water samples. Determined by the wet
oxidation method of Maciolek (1962).
5. Herbicides
Samples of 2 or 10 £ are treated with 5 g CaCl2 • 6H20 per liter
overnight under refrigeration. They are then filtered through a 47 mm
Gel man, type A, glass fiber filter. The filter is placed in a glass
thimble with anhydrous sodium sulfate and is extracted with a mixture
of 50 ml benzene and 150 ml methylene dichloride in a Soxhlet extractor.
The filtrate is first extracted with 80 ml benzene, then two times with
100 ml and 50 ml of methylene dichloride. The organic extracts are then
combined.
The organic extracts from (1) the filter (particulates) and (2) the
filtrate fractions are then concentrated, cleaned up on alumina columns,
and chromatographed (GLC) as described under the section on soils.
25
-------
The extracted filter is then stored in a freezer and shipped on
dry ice to the Athens, Georgia EPA laboratory for paraquat analysis.
6. Bacteria
Bacteria that are indicators of fecal pollution and water quality
are monitored. These bacteria are total coliforms, fecal coliforms,
total and fecal Streptococci and Salmonella. Water samples are collected
from the weirs in sterile bottles at weekly intervals. Collected samples
are properly treated to retain viability of the above bacteria and
returned to the laboratory within two hours of collection. The
identification of pathogenic bacteria involves procedures and techniques
recommended and described in Standard Methods for Examination of Water
and Waste Water (1971). Two methods are used for the identification and
enumeration of pathogenic bacteria, the Membrane Filter and Multiple
Tube Fermentation techniques. These techniques separate these organisms
based upon their physiological and temperature requirements such as
lactose fermentation, selenite, and azide tolerance, etc. Positive
cultures for Salmonella will be confirmed by using biochemical and
serological characters of these organisms. Isolated cultures will be
serotyped with Salmonella 0 group A - E antisera, Salmonella 0 poly
valent antisera, and Salmonella V^ antisera. All of the above antisera
are commercially available (Blair, et al, 1973). Total viable counts of
heterotrophic, aerobic bacteria are determined by standard plate counts.

June, 1976 under EPA contract WD-6-99-0766-J. Rhode River stations are
sampled once a month, year around. Other stations are sampled in April,
June, August, and October. Stations were selected in shallows (0.5 -
2 meters at mean low tide) in areas which are relatively protected from
wave action.

2. Submerged higher aquatic plants
A common steel garden rake is used to collect plants by scrapping the
surface of the bottom sediments in random paths in areas of 0.6 to 1.2
meters depth. A total area of bottom of from 10 to 100 square meters per
station is sampled, depending upon plant abundance. Samples of plants
from each station are sorted by species, counted, dried to constant
weight at 60° C in an oven and weighed. On site visual observations are
also recorded of presence or absence of plants.
The Shannon diversity index was calculated from plant population
(numbers) data by the formula:
Shannon Index = -z p^ In p^
where; p-j = number of individuals of species i per m2 divided by
o
the total number of individuals per nr
3. Habitat parameters
a. Salinity
Vertical profiles of salinity were determined at each station
with a Beckman model RS5-3 induction type salinometer calibrated
before each cruise with standard seawater.
b. Bottom sediment characterization
At each station 3 Pflueger cores were taken unless the bottom was
too hard in which case 3 Ekman Dredge samples were taken. These
samples were analyzed for percent organics, mineralogy, and mineral
particle size distribution. In the case of cores these parameters
were measured as vertical profiles. These parameters were determined
as in the section on soils.

Between stations the boat was operated at an even speed and
surface waters were pumped continuously from a depth of 0.5 m through
a flow-thru door (110-880A) on a Turner model 111 fluorometer. The
fluorometer had a F4T4-BL blue excitation lamp, a Corning 5-60
excitation filter, a Corning 2-64 emission filter, and a red
sensitive photomultiplier tube (R-136). The signal was recorded on
an integrating strip chart recorder. A sample of known volume was
taken at a marked time position on the chart for each transect
filtered through a Mi Hi pore HA filter, and the filter was dissolved
in 90% acetone saturated with MgCOg and stored in the dark. The
acetone extract was then analyzed for chlorophyll a by the method of
Loftus and Carpenter (1971). The average in vivo fluorometer response
was then determined by regression of the transect recording versus
the in vitro concentrations. Concentration of chlorophyll a was
determined by multiplying times the ug in vitro chlorophyll a, per
in vivo response unit from the regression.
b. Turbidity
A Hach, model 2100A, turbidimeter was used to measure the
turbidity of samples in the field. It was calibrated, in Jackson
units, with sealed standards before each measurement. Three samples
of surface waters were analyzed at each station.
c. Suspended particulate characterization
Surface water samples were filtered through prewashed and. weighed
Mi Hi pore HA filters. Weight gain was used to assay for total parti c-
ulates. Mineral particulates were determined after firing organic
30
-------
matter present in the sample. Size fractions and mineralogy were
determined as described by Carroll (1970).
d. Photosynthetically active radiation penetration
A Lambda model LI-185 quantum radiometer equpped with a LI-190S
quantum sensor and a LI-192S underwater quantum sensor was used,
beginning in the spring of 1977, to measure incoming PAR quanta flux
and underwater penetration of PAR to various depths.
5. Herbicide parameters (estuarine)
a. Sampling and extraction
At each station 15 £ of surface waters are taken and 50 g Ca C^
are added. The sample is allowed to stand overnight and is then
filtered through a Gilman, type A, glass fibre filter. The filter
is then treated with anhydrous sodium sulfate and extracted with
benzene and methylene dichloride. The filtrate is extracted with
benzene and then with methylene dichloride. Sediment cores (3) are
taken at each station with a Pflueger corer. In cases of hard
bottom conditions, a set of three Ekman dredge samples were taken.
These sediment samples were stored on ice until they could be
segmented (cores) into surface to 3 cm and 3 - 6 cm segments. Sub-
samples of 10 g weight were then mixed with 10 g anhydrous sodium
sulfate and extracted with benzene and methylene dichloride
b. Cleanup and GLC
These steps were carried out as described under soils.

VII. Submerged Aquatic Plant/Herbicide Bioassays
1. Growth Conditions
Two 4 foot x 8 foot x 1 foot (deep) steel water jackets were.built,
insulated with styrofoam, and equipped with recirculating thermostated
water chillers (Neslab model CF 75 with PD-2 pumps). Two 4 foot x 8 foot
reflector lined fluorescent light banks were built. Each contains 24 -
80 watt fluorescent units with daylight type tubes. The light banks
are on timers set for 16 hour photoperiods. Vycor immersion heaters
were used to provide a constant heat load to the water jackets and the
temperature was maintained at 23 C. One water jacket was used to
temperature control 9-20 gallon all-glass aquaria, which are used as
holding tanks for experimental plants. The second water jacket was used
to temperature control 16 - 10 gallon all-glass aquaria for test
(bioassay) purposes. All aquaria were aerated with air from two commer-
cial aquaria compressors. Aerators are horizontal tubes with small holes
every inch of their length which run the full length of the aquaria.
They are regulated with needle valves and their depth can be adjusted.
Glass plates are kept over 90% of the surface of each aquarium. Forest
soils from watershed 110's drainage channel were analyzed for particle
size distribution, mineralogy, and percent organic matter to select a
sample for tank bottom sediments which best matched conditions at station
30.5 (Figure 6). This was done to assure a noncontaminated baseline in
the aquaria, since no herbicides have ever been used within approximately
one mile of watershed 110. In addition, samples were analyzed for
herbicides. Each tank was filled to a depth of 5 cm with this soil.
Herbicide, in alcohol or methanol, was added to a calculated concentra-
tion and was well mixed. Plants were transplanted into the soil
32
-------
(approximately 200 young ZannicheTh'a palustris per tank in the first
experiment). Well water plus enough instant ocean salt mixture
(Aquarium Systems, Inc.) to bring it to 5 parts per thousand was added
and it was aerated until the pH was about 8. The next day, after
excessive turbidity had subsided, herbicide was added to bring the
water to a level calculated to be a thousand fold lower in concentration
than the sediments. Eight tanks were used to assay atrazine effects and
eight for linuron effects. In each case two banks were controls
(untreated), two were given 1 ppm of herbicide in the sediments, two
were given 10 ppm of herbicide in the sediments, and two were given
100 ppm of herbicide in the sediments. Experiments were carried out for
four weeks from herbicide addition.

2. Assays
Tanks were routinely monitored for water temperatures and turbidity.
Photosynthetically active radiation was measured. At the surface of the
light banks PAR was 430 y E/m^ sec. At the water surface in the aquaria
o
PAR varied from 80 to 140 y E/m sec. Subsainples of plants were bio-
assayed two times a week by washing off the accumulated growth of algae
and sediments then placing them in BOD bottles filled with Millipore
HA filtered well water which had been adjusted to the same salinity and
33
-------
pH as the test tanks. A YSI BOD oxygen electrode probe was then
inserted in each bottle and the bottle was floated in the water jacket
under the light banks. Each assay was routinely begun at the beginning
of the 8 hour dark period. DO was read after thoroughly mixing the
bottle contents at 0, 4, and 8 hours of darkness, then at more frequent
intervals during the light period. The plants from each bottle were then
counted and their length and dry weights were measured. The data points
for dark and light DO sets were then subjected to linear least squares
regression to obtain DO slopes for respiration and photosynthetic rate
estimates.
3. Herbicide sampling
Bottom sediments from each tank were sampled at the beginning and
end of the four week run. Water samples were taken (one liter each)
once a week and were not replaced. Samples were analyzed as described
in other earlier sections.

QUALITY CONTROL IN HERBICIDE ANALYSES
To insure the precision and accuracy of the application of the analytical
method, a quality control program has been set up at CBCES for herbicide
analysis. The quality control program is one of the most important parts of
the herbicide analysis, and is the result of discussions with William Payne
and Jackie Benner of the Environmental Protection Agency, during their recent
visit to CBCES concerning herbicide analyses performed under EPA Grant Number
R804536-01.
The results from trace analysis of environmental samples are obtained
through many steps in the laboratory. Analytical methods, quality control of
instrumentation performance, computer handling and data analysis are all
important toward generating reliable analytical results. The CBCES Quality
Control Program is designed to handle large numbers of samples and to emphasize
the fact that these samples should be handled with the utmost care in the
preparation stage. Generally, the three most common difficulties with any
type of trace analysis are (1) Impurities imparted from the chemicals that are
used in the sample handling processes, (2) Contamination from glassware and
other containers, and (3) Errors made due to unsatisfactory personnel
performance.
(1) Impurities from chemicals - Blank Test
The major materials used in the herbicide analytical process that should
be tested for impurities should be solvents, filters, alumina, and anhydrous
sodium sulfate. Dichloromethane, benzene, hexane, acetone, and petroleum
ethers are all nanograde solvents from Mallinckrodt Inc. Filters are purchased
from Gelman Co. (Type AE) and are throughly cleaned in the CBCES lab as
described later in this section. Alumina and anhydrous sodium sulfate are
35
-------
purchased from Applied Science Laboratories, Inc. All of these chemicals are
suitable for trace analysis of pesticides. The quality control program ensures
that the low level of impurities present in these materials are monitored
through the use of blank tests.
A filter that is cleaned through the use of the filter cleaning process,
is extracted in a Soxlet extractor and processed through the entire procedure
as if it is a routine sample. One blank test is necessary every week. All of
the blank test results will be tabulated and dated for background information.
(2) Contamination from glassware - Cleanliness Test
• Almost all of the containers in the herbicide analysis are pyrex glassware.
Glassware is cleaned with water, soap, and with chromic acid. It is rinsed
throughly with tap water, and finally with distilled water. The glassware is
then dried in the oven at 100° C overnight before use.
Inspection of the cleanliness of the glassware should be made constantly.
Benzene is used as a test for herbicide contamination. After rinsing the glass-
ware with benzene, the benzene solution is tested with a gas chromotograph.
Other precautions concerning contamination from glassware include the
following:
(A) Do not store herbicide standards and commercial herbicides with
sample extracts in the same refrigerator.
(B) Avoid making herbicide standards in the same hood that is used for
sample preparation.
(3) Unsatisfactory personnel performance - Spiked Sample Test
Laboratory personnel involved with the herbicide analyses for the EPA
project are those who have had at least four years of college education, and
are chosen on a competitive basis. Judgment was made based on academic
standings, skillfulness of chemical analysis, enthusiasm, and interests in
chemical research, and recommendations from their previous supervisors.
36
-------
Training and education of CBCES personnel for herbicide analysis are
one important step toward a good quality control program. The broad over-
view of the entire research program, its goal and significance, is explained
and discussed, detailed laboratory procedures are explained and demonstrated.
Regular discussion sessions are held at least once a month in order to
exchange ideas and to evaluate suggestions for improvements. It has been
made clear, however, that nothing should be changed from our routine course
of analytical procedure. We all follow the procedures that are outlined in
this manuscript. Every day visits and observations of the skillfulness of
operations, neatness of the laboratory and other essentials are the duty of
the CBCES research chemist. Corrections will be made when it is necessary in
order to maintain a successful program.
Occasionally a spiked sample test will be given to each of the laboratory
personnel. The test will not be known to the person. This can be done by
substituting a standard herbicide mixture for a CBCES numbered sample, or a
sample can be spiked with a standard herbicide mixture. Spiked sample tests
can be done for the entire procedure or they can be just for a particular step.
The detailed method is the same as described in the precision and accuracy
section. The results will be made known and will be used for judgment of
skillfulness and carefulness of the laboratory personnel. Improvements in
quality control and in the reliability of our analytical results will result
from these routine quality control measures.
37
-------
Filter Cleaning
Gelman glass fiber filters (Type AE, 142 mm, no organic binder) are
precleaned according to the following procedures:
1. Soak a batch of the Gelman filters in distilled water for one day,
drain the water from the filters and oven dry the filters at 60° c for
24 hours.
2. Put the dried filters into the side chamber of a large extractor and
extract with a mixture of 2.5 £ of 2/1 methylene chloride and benzene
for 72 hours.
3. Air dry the filter under the hood and wrap with aluminum foil until
dry.
38
-------
Precision and Accuracy
The precision and accuracy of the entire analytical procedure for
herbicide analysis can be determined by a standard recovery study. In order
to determine the effectiveness of each step of the analytical procedure, a
recovery study of each step is conducted (refer to following schematic for
steps).
1. Addition to natural samples
To wet soil, wet sediment, particulate sample or filtrate sample 4 ml
of standard herbicide mix is added, and then the entire analytical
procedure is carried out. Before the standard addition to these various
forms of natural samples is performed, a major effort should be made to
determine the effectiveness of the procedure itself. This can be
accomplished by pippeting 4 ml of standard herbicide mixture into an
empty Soxhlet extractor and proceeding as if there is a sample, and thus
the complications due to adsorption and other effects can be eliminated.
2. Addition to organic solution I
Add 4 ml of standard herbicide mixture to organic solution I and
proceed as usual. The difference between the percent recovery of this
addition and the previous one will reveal the effectiveness of the
Soxhlet extraction.
3. Addi ti on to concentrate I
Add 4 ml of standard herbicide mixture to concentrate I just before
the cleanup procedure. This will enable us to determine the loss (if any)
due to the Kuderna-Danish evaporation process.
4. Addition to organic solution II
Add 4 ml of standard herbicide mixture to organic solution II. The
39
-------
comparison between this and the previous one will determine the percent
recovery of the column chromatographic cleanup procedure.
5. Addition to concentrate II
Add 4 ml of standard herbicide mixture to organic concentrate II.
The GC analysis will determine the matrix effect of the sample extract.

RESEARCH RESULTS FROM WATERSHED PROGRAM
Status of Watershed Activities
The major goals of the first year of the grant included (i) the construc-
tion and instrumentation of three V-notch weirs on cornfield, woodlot, and
pasture field-sized watershed; (2) the instrumentation of these watersheds,
(3) a major effort to obtain a full set of data on the application of agricul-
tural herbicides and fertilizers to the cornfield watershed and the composition
of the runoff from this watersheds; and (4) the analysis of volume-integrated
samples from our previously instrumented basin-sized watersheds for herbicides
and heavy metals.
By April 9, 1976 the cornfield weir site and watershed had been selected
and baseline soil samples were taken. Soil sampling stations were established.
A temporary, manual, rain gauge was put in position on this watershed on April
15 and total rainfall per storm, as well as the approximate time and duration
were recorded. A detailed map of watershed 109 is given in Figure 3. Record-
ing rain gauges (3) were ordered in June when funding was made available and
have now been received. Three more were ordered in September when permission
was received and have now been received. Additional manual gauges v/ere also
purchased and all are now in place as shown in Figure 6. A 120 V-notch weir
and instrument shed were built and instrumented to take volume-integrated
samples (only) by May 7 when corn planting commenced. A fraction collector
was designed and six were constructed. One is in use on each of the field-
sized watersheds. Fertilizer and herbicide application rates were measured
and soil cores were taken daily for herbicides, every two days for nutrients
for the first week, then with decreasing frequencies with time. Soil core
samples were stored in a freezer until analyses could be performed and the
42
-------
backlog of herbicide samples has not been overcome yet. Weir samples of
runoff were analyzed for all parameters planned. Vertical color photos were
taken at each of five stations every ten days during the growing season from
an elevation of 6 meters. Each time these were taken corn heights were
measured and at several times during the growing season the weight and nutrient
contents of the roots, stems, leaves, and ears were measured. At the end of
the growing season the corn and weed populations were also surveyed (number,
above ground biomass, and leaf area per square meter) for each species in a
series of random plots near each station.
As of mid-June we began to analyze all volume-integrated water samples
from basin-sized watersheds (8) for selected herbicides and heavy metals as
proposed. As of July 19 we began shipping one gallon subsamples from the
basin watersheds and the cornfield watershed to the Athens, Georgia EPA
laboratory for herbicide analysis. Many of the streams were dried up during
this time due to a very dry year so shipments averaged only a few samples per
week. At that time we also began shipping to Athens, Georgia the solvent-
extracted filters containing the suspended particulates from weir samples.
These were to be analyzed for paraquat in Mr. Payne's laboratory. In October,
we stopped shipping water samples to Athens, at the request of EPA. Only
suspended sediment and bottom sediment samples are now shipped to Athens for
the analysis of paraquat.
In late July and August the weir and instrument shed for the woodlot
watershed were constructed and instruments were installed for volume-integrated
water sampling. In the spring of 1977, soil moisture and temperature stations
were established (see Figure 4). Severe ice and frozen soil conditions broke
the foundations of the weir in early January 1977, and it was not repaired
until mid-April, at which time sampling was begun again.
43
-------
A pasture watershed was selected, permission to build a weir and carry
out studies there were obtained from the owner, and weir construction has been
completed. Soil stations with temperature and moisture probes have been set
up (see Figure 5). Weir instrumentation should be complete by July 1, 1977.
Land use practices surveys are ongoing.
In July, Dr. Correll visited the Iowa State University non-point pollution
study and discussed their work with these investigators, at the same time he
visited with Rob Johanson and Tony Donigian from Hydrocomp who were visiting
the Iowa site. As a result, we modified some of our sampling (e.g. we now run
distilled water extractable orthophosphate and ammonia, put in deeper soil
moisture and temperature probes, and measure total-P, and total-N in soils
less frequently).
We have purchased and received the budgeted explosion-proof refrigerator
and deep freezer and the twin-shell blender. We have received a 10 by 12 foot
walk-in cold room, and it is in use. Our Packard GC system is working well.
We have ordered and received a Tracor GC system with a Hall detector and they
are now operating satisfactorily. Our amendment request to increase funding
for herbicide analyses for watershed samples has been received and implemented.
A sediment splitter apparatus for storm water samples from weirs has been
constructed and is in use.
Rainfall and Soil Temperature/Moisture
Table 2 lists rainfall daily totals for watersheds 109 and 110. Storms
of over 2.5 cm were recorded in 1976 on May 1, May 29 -31, June 16, July 11,
July 16, August 7-9, August 14 - 15, August 27, September 15 - 17,
September 30 - October 3, October 9, October 20, October 24 - 25, October 30,
and December 7. We had an unusually wet summer and fall. In 1977 storms of
44
-------
over 2.5 cm were recorded on January 1 - 12, March 22, and April 2-5. Soil
moisture data are tabulated for manual gravimetric determinations on cores
(Table 3A) and for gypsum block sensor data (Table 3B). Data on soil tempera-
tures for watershed 109 is in Table 4. Soil moisture data from 75 cm depths
on 109 and at all depths for 110 were not included because they have not been
calibrated.
Cornfield Plant Populations
Soil coverage and corn heights are shown in Figure 11. Since fields 3
and 4 were planted later, data from those fields is plotted separately. By
mid-July plant heights and soil coverage had reached their maxima, approximately
80% and 290 cm, respectively.
The relationship between corn height and soil coverage is shown in
Figure 12. This relationship is so clear that it was considered unnecessary
to measure soil coverage in 1977. Corn leaf area index at four times are
listed in Table 5 and graphed in Figure 13. Leaf area index for the corn plants
averaged 3.1 on July 23 and declined to 2.9 in August and September.
Corn plant populations and nutrient withdrawal data are given in Table 6.
Total phosphorus withdrawal peaked at 5.7 g P/m2 in fields 1 and 2 and
4.3 g P/m2 in fields 3 and 4 on September 3. Total Kjeldahl nitrogen with-
drawal peaked at 28.6 g N/m2 for fields 1 and 2 and at 25.7 g N/m2 for fields
3 and 4 on September 3. In both cases most was in the aboveground corn biomass.
2
Corn total biomass per m is plotted in Figure 14. Above and below ground
biomass is plotted in Figure 15. The relationship between total corn biomass
and corn height is given in Figure 16. Total phosphorus in corn plants at
various ages is plotted in Figure 17. This is broken down into above and below
ground total phosphorus in corn plants in Figure 18. Total Kjeldahl nitrogen
45
-------
in whole corn plants is shown in Figure 19 and this is shown for above and
below ground plant parts in Figure 20. Tables 7 and 8 give a detailed break-
down of the composition of corn plant parts at various times (Table 7 is
total phosphorus, Table 8 is total Kjeldahl nitrogen). Table 9 gives details
of the dry weights for corn plant parts and their nutrient content per plant.
Table 10 contains dry weight to fresh weight ratios for corn plant parts.
It was noted that all during the growing season, weeds of several species
were abundant in the cornfields even though herbicides had been applied.
Weeds accounted for a significant percentage of ground cover and no doubt a
significant amount of nutrient removal. Therefore, some effort was made to
measure the weeds. Table 11 is a checklist of weeds commonly found in the
cornfield. Table 12 has data on weed populations in the fall of 1976. Weeds
were more abundant earlier in the season but no study was carried out then.
During the 1977 season more effort has been expended upon this aspect of the
plant populations. Corn population studies were also focused in 1977 on the
early part of the growing season.
Cornfield Soil Compositional Studies
Table 13 gives mean bulk densities of the soil at each station at three
depths. Table 14 gives the estimated soil mass per square meter in each slice
of depth analyzed routinely in 1976 for the cornfield. Table 15 gives soil
composition on the cornfield in terms of sand, silt, clay, and organic matter.
Table 16 contains the mineral composition of the silt and of the clay fractions
in the cornfield. Table 17 gives detailed soil nutrient compositions at
various times, as well as pH and organic carbon levels. Table 26 gives the
soil nutrient pool sizes for the cornfields in various soil slices. Table 18
gives all the soil herbicide analyses from the cornfield which have been
completed at this time. 46
-------
Land Use Practices Data
Table 19 gives estimates of the rates of application of fertilizer and
herbicides to the cornfields of watershed 109 in 1976 as measured by a
series of different techniques. Table 20 gives data on harvestable corn
production on the cornfield. Of the estimated 39.7 Kg/ha of phosphorus
applied, about 15 were removed in the harvest. Of the estimated 167.4 Kg N/ha
applied, about 90 were removed in the harvest. Table 21 gives summary data
of the application rates for pesticides and fertilizers by farmers on each
monitored watershed. It also gives livestock population data. Table 22 is a
summary of the progress made so far on land use practices used by residential
and business populations. The data obtained is much less accurate and
detailed than was the case for the farmer survey.
Data on Runoff Waters from Watersheds
Table 23 gives the results obtained thus far on the bacterial composition
of runoff from the cornfield (109) in part A, the wooded watershed (110) in
part B, and the pasture watershed (111) in part C. Table 24 gives the
suspended particulate composition data obtained from 109 and 110. Table 25
contains nutrient discharge data for 109 and 110. A special effort was made
to tabulate as much data for spring of 1977 as possible to allow a better
comparison to be made of nutrient discharges from 109 and 110 for last fall
and this spring. Table 26 gives suspended particulate and nutrient data for
a small storm event on the cornfield watershed, which occurred on April 24,
1977. The hydrograph is shown in Figure 21. Our new fraction collector was
in place and six discrete samples, as well as a volume-integrated sample were
collected. No other significant runoffs occurred until late in-June. Table 27
47
-------
has the data which has been processed so far on herbicide discharges from 109,
110, and from seven basin-sized watersheds. Table 23 lists the samples which
have been analyzed for paraquat in Athens, Georgia. None of these had detect-
able levels of paraquat, but that is not very surprising since none of the
farmers on these watersheds use paraquat (See Table 21). Samples from flux
sections (especially number 122) would be more likely to have paraquat due to
tidal action.

RESEARCH RESULTS FROM ESTUARINE PLANT/HERBICIDE RESEARCH.
Status of Activities
Sample collecting
The 12 stations on the Choptank River (Figure 8) and at the Poplar
Islands (Figure 9) described in the methods section were sampled in June,
August, and October 1976 and again in April and June 1977. The five Rhode
River stations (Figure 7) were also sampled every month from April 1976 to
June 1977, except in January and February when heavy ice conditions prevented
sampling. Data was also collected at six stations on the Severn River
(Figure 10 and methods) in June of 1976.
Laboratory bioassays
Plant bioassay equipment has been purchased and installed. Sixteen 10-
gallon and nine 20-gallon glass aquaria in temperature controlled water baths
are in use. They are illuminated by timer controlled fluorescent light banks.
Five cm of pesticide free soils, selected to match Rhode River station 8.5
bottom sediments with respect to % of sand, silt, clay, and organic matter,
as well as mineralogy, are placed in each tank and synthetic brackish water
is used. One series of plant assays on horned pondweed (Zannichellia palustris)
has been completed against 0, 1.0, 10, and 100 ppm of herbicide in the bottom
sediments. Two herbicides, atrazine and linuron, were used and each of the
eight herbicide/concentration conditions was replicated. Herbicide concentra-
tions in bottom sediments, solution, and suspended sediments were assayed at
the beginning and end of each experiment and the dissolved/suspended fractions
were assayed weekly during the experiment. Bioassays are run by selecting
subsamples of plants, transferring them to BOD bottles, measuring rates of
oxygen release in the light and uptake in the dark with Clark electrodes,
49
-------
then measuring, drying, and weighing the plants. A second series of assays
is in mid course now on Potamogeton pectinatus. (Sago pondweed). A third is
planned on eel grass (Zostera marina).
Data from field activities
Table 29 contains data on submerged plant populations. Table 30 contains
detailed data on bottom sediment characteristics such as percent sand, silt,
clay, and organic matter, as well as the mineralogy of the silt and clay
fractions. Table 31 gives data on suspended particulates in the surface
waters and Table 32 gives salinity, turbidity, and light penetration data.
Table 32 contains phytoplankton chlorophyll a concentrations.
Table 34 has all of the currently processed estuarine herbicide data.
Part A is for surface waters and part B for bottom sediments. In general,
whole surface waters have a thousand times less herbicide than bottom sediments,
but the suspended particulate fraction, on a weight basis, has the highest
concentrations.
Bioassay data on Zannichel1ia palustris
Table 35 has bioassay data from plants collected at station 30.2
(Figure 7) and immediately assayed in filtered estuarine water at depths of
20 and 50 cm. The same plants in the same water were then assayed in the
laboratory under standard temperature and light conditions. Table 36 gives
the data from a four week series of bioassays in the laboratory of plants
exposed to various concentrations of linuron or atrazine. Table 37 gives the
average response to linuron or atrazine in terms of net oxygen release per
day per gram of dry weight (Part A) and in terms of gross photosynthetic rates
(mg 02/hr g dry wt) in part B. The data for shoot length versus time are
given in Figure 22A for atrazine and Figure 22B for linuron. Data for plants
50
-------
exposed to 10 or 100 ppm of herbicide (in the sediments) ends before four
weeks are over because all remaining plants had died. A considerable amount
of variability especially between microcosms is seen in the data and confi-
dence limits have not been established. Control shoots grew on the average
twice as fast as those exposed to one ppm of atrazine and eight times as fast
as those exposed to one ppm of linuron. Figure 23A shows the change with
time in net daily oxygen production for plants exposed to atrazine and
Figure 23B gives the data for plants exposed to linuron. Control plants
produced less oxygen initially than those exposed to one ppm of herbicide,
but end up producing more oxygen in the last week. The differences were not
very large. Figure 24A gives the change in gross photosynthesis with time
when plants are exposed to atrazine.' Figure 24B gives data for change in
gross photosynthesis of plants exposed to linuron. It is obvious in the
case of growth, net oxygen production and gross photosynthesis that 10 or
100 ppm of either linuron or atrazine is very inhibiting and leads to plant
death. In the case of one ppm in the sediments the effects are much less
clear-cut.
These data are preliminary, in that only one species of plant has been
assayed and the data have not been thoroughly tested statistically. However,
the field data indicates the widespread presence of both linuron and atrazine
in Chesapeake Bay, The concentrations seem at this time to be in the range
V
which might inhibit submerged higher plants. Finally, it is known that these
compounds can act synergistically.

Footnotes to Soil Moisture Data Tables
1. Equations for calibration of station 7 at 15 cm and 30 cm and of
station 10 at 15 cm and 30 cm were derived from the mean moisture content
for a common moisture reading (resistance) and from the mean Y intercept
obtained in the gravimetric calibration of all other probes at the same
depth. All other probes were calibrated using a linear least squares
regression of the gravimetric data taken adjacent to the probe.
2. Beginning January 5, 1977, soil moisture data is also available for
a depth of 75 cm. The probes at this depth have not yet been calibrated
and therefore, this data has not been included in the table.
