ATMOSPHERIC LOADINGS TO
WATERS OF THE FOUR
UPPER GREAT LAKES
A STATUS REPORT

Charles T. Elly
Surveillance and Analysis Division

Central Regional Laboratory
Chicago, Illinois 60605
February, 1980
-------
RECOMMENDATIONS
The existing EPA, Region V network of 30 bulk samplers on land should be
continued. To strengthen the atmospheric loading program, wet-dry or
"event" samplers should be added to 20 of the sites. That would enable
measurements of total loading and wet deposition. Dry deposition could
be estimated by difference.
Field and laboratory functions of the atmospheric program should be
contracted. Collection of the samples should be contracted to one
company which can in turn subcontract to those operators who actually
collect the samples. Laboratory analyses should be done at the CRL
by a contractor. All analyses should be completed within two weeks
after arrival at the CRL. " - '
A regional study plan is currently being drafted which recommends re-
placement of 30 bulk samplers with wet-dry "event" samplers. However
this program is not expected to be operational until next fiscal year,
if approved.
The Region V EPA, and R&D atmospheric programs should be coordinated by
the SXA Senior Research Advisor so that data are available to both programs
on a timely basis. Alternately, those stations operated by R&D should
not be included in the Region V study.
Arsenic, copper, cadmium, chromium, lead and silver should be analyzed
by flame!ess atomic absorption or other means which will readily attain
detection limits of 0.1 ug/1.
Future atmospheric sampling should include PCB's pesticides and other
organics, but this will require modification of the samplers.
Samplers at Superior, Wisconsin, Silver Bay, Grand Marais and Two Harbors,
Minnesota should be relocated out of the influence of industrial activity.
The sampler at Port Sanilac should be discontinued and moved to the coast
guard station at Alpena, Michigan. Other station locations are acceptable.

Despite analytical and operational problems which plague the atmospheric
loading program, data cited in this report should be merged with Canadian
data so that final loading estimates for nutrients, metals and minerals
can be calculated for each Great Lake. IJC sources have commented to
the author, that American-Canadian data cannot be merged until the Great
Lakes Commission gives its approval. This is not expected to happen
before the November, 1980 meeting. Final percentage contributions of the
parameters cannot be tallied until data from both sides of the border
are assembled.
CONCLUSIONS
Based on data collected by bulk precipitation samplers, significant con-
centrations of minerals, nutrients, solids, calcium, magnesium, zinc, lead,
iron, and aluminum are being deposited to the four upper Great Lakes
from the atmosphere.
Average pH values were less than 5, which indicated that the combined
materials deposited to the lakes were acidic.
Metal loadings to Lake Superior near Minnesota appeared to be higher
than at the other stations due to local industrial influences. While
data are higher, and the samplers may have to be moved, nevertheless,
industrial operations are adding significant loadings to Lake Superior.
Data were incomplete at many of the Region V operated stations and all
of the EPA, R&D operated stations. The reasons are due to operational
problems involving volunteer operators and lack of timely analysis by
CRL and R&D.
Metal samples were analyzed by inductively coupled plasma, which resulted
1n many values which were reported at "less than". The method is not
sensitive enough for lead, cadmium, silver, copper, chromium and some
other transition metals of interest.
-------

There are many inherent problems in the bulk precipitation collector program,
such as the design of the sampler, the constant leakage of plastic bags,
improper usage of bug screens, shipment of supplies, careful examination
of field sheets to determine whether the samples are valid, and many
other problems which make it difficult to get a valid sample each month.
The program needs more overall (internal or external) management
devoted entirely to atmospheric loading.
Sampling was not conducted for pesticides, PCB's and other organics. The
original study plan called for sampling twice per year on a grab basis.
It is impossible to take samples out of the bulk samplers because the
collectors are plastic bags.
' ' "-v-
The precision of the overall process as estimated by usage of paired
samplers at Cudahy and Superior, Wisconsin was 22% and 39% respectively
at those sites.
OBJECTIVES
The purpose of this study was to estimate total atmospheric loadings to
the waters of the four upper Great Lakes for selected chemical parameters.
The chemical parameters were chosen because some are known to be toxic,
while others may contribute to eutrophication of the lakes. Due to
incomplete data at some stations, and other shortcomings of the study,
this report represents both a summary of the loadings and deficiencies
of the study program.
INTRODXTION
The quantity of material input to the waters of the Great Lakes from the
atmosphere impacts significantly on the water quality of the lakes. For
example, atmospheric inputs (wet and dry deposition) make up about 19%
of the total phosphorus loading to Lake Superior and 11% of the loading
to Lake Huron (ILL. R.G. Vol I, 1977). In addition, atmospheric loadings
are estimated to contribute 30-40% of the total metal loadings to the
upper Lakes as well as being a primary pathway for synthetic organics
to these water bodies.
-------
-4-
Atmosphen'c contributions to the Lower Lakes are somewhat less significant,
as Shiomi and Kuntz (1973) and Kuntz (1977) have Indicated that between 5
and 15% of the loading for N and P are contributed to Lake Ontario by
the atmospheric processes and about 51 of the P loading to Lake Erie
is from this source.
To date, studies have measured the total loading (both wet and dry
deposition) to the lakes; so called "bulk-precipitation" measurements.
Currently, new samplers on the Canadian side are being used to determine
the relative contribution of wet and dry deposition to the total loading.
Data collected in this study were acquired using modified bulk-precipitation
collectors, located within the American boundaries of the Great Lakes.
Data will be eventually merged with Canadian atmospheric loading data
to acquire total loadings for the Great Lakes.
This study also includes data on pH, specific conductance, sulfatest
chlorides and nitrates, which can be used to supplement acid rain data
sought by researchers and surveillance personnel.
DESCRIPTION OF SAMPLING PROGRAM
Modified bulk precipitation samplers were located in the 30 areas listed in
Table 1 and shown on Figure 1. These sampling site areas were selected
to give representative information concerning variations in precipitation
and dry particulate matter chemistry within the major agricultural,
forested, and industrial/urban regions considering the best available
knowledge of ..prevailing winds, source of atmospheric pollutants, prevalent
forms of deposition, frequency and amount of precipitation events, and
other meteorological and physical processes.
Figure 2 is a drawing of the original bulk precipitation collector.
The original collector was modified by adding two additional standpipes
to It In order enable analysis of preserved samples. The three-moduled,
modified bulk precipitation collector enable analyses of pH, conductance

and other minerals from the unpreserved standplpe, nutrients (nitrogen
and phosphorus) from a sulfuric acid preserved module and total metals
from a nitric acid preserved module.
Samples were collected monthly by the volunteer operators (whose names
are listed in Table 1) and mailed to the EPA, Region V, Central Regional
Laboratory (CRL) in Chicago, Illinois. In the field, the contents of
each bag were poured into one liter bottles. The excess volume over one
liter was recorded on a data sheet for each sample type (minerals, nutri-
ents, metals) and the excess water in each bag was discarded. Final
volumes were calculated by summing one liter plus the excess volumes in
each bag. During months when precipitation was low and there was insuf-
ficient water to fill to the one liter mark of the bottle, the volume
was measured (by weight) and recorded in the laboratory.
ANALYTICAL PROCEDURES
Bulk precipitation samples were analyzed using water analysis procedures.
Dry deposition matter adhering to plastic bags were leached with acid and
distilled water and analyzed as water samples. The collector bags for the
unpreserved samples were not leached with acid.
All demand parameters were analyzed by standard EPA procedures. Nutrient
samples were preserved with 12 ml of 33% sulfuric acid, and metals samples
were preserved with 12 ml of 33% nitric acid, which produced concentrations
greater than 2 ml sulfuric and nitric acids per liter of sample for the
large majority of samples. These procedures are defined in the 1974
edition of "Methods for Chemical Analyses of Water and Waste", EPA
Publication No. EPA-625/6-74-003.
All metal parameters, except mercury were analyzed using the CRL inductively
coupled argon plasma atomic emission spectrometer (ICAP-AES) procedure.
Mercury was determined via a CRL semi-automated method (Anal, Chem., 48,
110, 1976).

QUALITY ASSURANCE
Paired bulk samplers were Installed and operated at Pinconnlng, Michigan,
Chicago, Illinois, Milwaukee Superior, Wisconsin, to estimate the precision
for the total process (sampling, sample transportation, and analyses)
for each parameter.
RESULTS
Appendices I and II contain parameter concentration and loading data for
30 stations for the period August 1978 to July, 1979.
Parameter concentrations are expressed In milligrams per liter (mg/1)
for minerals, nutrients and solids, micrograms per liter (ug/1) for
metals, micromhos per centimeters (umhos/cm) for specific conductance
and pH units for pH.
Parameter loadings are expressed milligrams per square meter per day
(mg/M^/day) for minerals, nitrients and solids, and micrograms per
square meter per day (ug/M^/day) for metals. Loadings are not expressed
for pH and conductance.
The following factors were used for calculation of loading.

Significant loadings for minerals, nutrients, solids and several metals
were deposited on the four Upper Lakes.
Higher loadings occurred on the Ohio shoreline and in areas of higher
industrial activity.
Higher than average loadings of aluminum, iron, zinc, titanium and lead
were deposited on Lake Superior, at Bayfield and Superior, Wisconsin,
Grand Marais, Silver Bay, and Two Harbors, Minnesota. It appears that
the heavy loadings are due to fallout from on-shore ore operations
especially at Superior, Wisconsin.
The pH of the atmospheric samples averaged approximately 4.5 overall,
with the low (2.1) and high (7.9) being measured at Bayfield, Wisconsin
and Ontanagon, Michigan respectively, two remote areas.
The acidic precipitation at nearly all of the stations appeared to be
related to either the sulfate, chloride or nitrate data.
Data were incomplete for many of the stations operated by Region V personnel
including Port Sanilac, Glen Haven, Chicago and Zion, Illinois. The
station at Isle Royal National Park is only operated during the park's
open season.
Data are not reported for stations 7 through 12. These stations are
part of the American network of stations but are operated by EPA, Research
and Development personnel. Many of the analyses were done at the CRL.
Table II contains paired sample data for each parameter. Two samplers
were located approximately 100 feet or less apart from each other at
Milwaukee (Cudahy) and at Superior, Wisconsin to estimate the precision
of the total collection and analysis process. The values in Table II
represent the daily average loading values (in mg/M^/day and ug/M2/day)
from August 1973 to July 1979 for most parameters. The precision (or
percent deviation) data were estimated by the following formula:
-------
-8-
Flrst Value - Second Value x 100 % Deviation
Highest Value of the Two
The overall precision was 22% at Milwaukee at 39% at Superior. At this
time, an explanation cannot be given for the differences inprecision.
However, the precision of the overall sequence of deposition (rain, snow,
dry fallout), sample collection and handling, plus laboratory analysis
was suprisingly good considering the number of variables involved.
The design of the samplers are such that evaporation or volatilization
may be factors influencing the analytical results. Studies were not
conducted regarding these factors.
