16. Abstract (Limit: 200 words)
The U.S. Geological Survey is monitoring the water quality of three major
tributaries to the Chesapeake Bay at their fall lines to obtain estimates of con-
stituent inputs potentially available to the bay. The monitoring sites are:
Susquehanna River at Conowingo, Md.; Potomac River at Washington, D.C.; and James
River at Cartersville, Va. Water-quality data collected from October 1978 to
April 1980 are presented in tables. Concentrations of major ions, nutrient and
carbon species, metals, pesticides, suspended sediment, and other selected con-
stituents are presented for a range of flows. The mean, standard deviation,
minimum, maximum, and median values for each constituent were determined by stand-
ard methods and are presented for each sampling station. Bivariate linear regres-
sions were run for all constituents versus streamflow, specific conductance, and
suspended sediment. Those relationships exhibiting coefficients of determination
greater than 0.50 are tabulated.

DEFINITION OF TERMS
Terms related to streamflow and water quality as used in the report
are given below:
Alkalinity is the capacity of a water to neutralize acids. Alkalinity
in water is caused primarily by bicarbonates, carbonates, and hydroxides,
and is expressed as equivalent calcium carbonate, CaCO .
Chlorophyll a is the primary pigment of all oxygen-evolving photo-
synthetic organisms and is present in all algae and photosynthetic organ-
isms, except some photosynthetic bacteria (Wetzel, 1975).
Chlorophyll b, although common to higher plants, is found in green
algae and other lower plants. This pigment functions as a light-gathering
pigment in which absorbed light energy is transferred to chlorophyll a for
primary photochemistry (Wetzel, 1975) .
Cubic foot per second (CFS, ft /s) is the rate of streamflow repre-
senting a volume of 1 cubic foot passing a given point during 1 second and
is equivalent to 7.48 gallons per second or 448.8 gallons per minute.
Fecal coliform bacteria are bacteria that are present in the intes-
tines or feces of warmblooded animals. Their presence in water is con-
sidered to indicate fecal pollution. In the laboratory, they are defined
as all organisms that produce blue colonies within 24 hours when incubated
at 44.5 ±0.2°C on M-FC medium (selective nutrient medium for fecal coliform
growth). Their concentrations are expressed as number of colonies per 100
milliliters (mL) of sample.
Fecal streptococcal bacteria are bacteria that are present in intes-
tines or feces of warmblooded animals. Their presence in water is con-
sidered to indicate fecal pollution. They are characterized as gram-
positive, cocci bacteria which are capable of growth in brain-heart in-
fusion broth. In the laboratory, they are defined as all the organisms
which produce red or pink colonies within 48 hours at 35 ± 1.0 °C on M-
enterrococcus medium (nutrient medium for fecal streptocci growth). Their
concentrations are expressed as number of colonies per 100 milliliters of
sample.
Hardness of water is a physical-chemical characteristic that is com-
monly recognized by the increased quantity of soap required to produce
lather. It is attributable to the presence of alkaline earths (principally
calcium and magnesium) and is expressed as equivalent calcium carbonate,
CaC03.
Kjeldahl nitrogen is the sum of free-ammonia and organic nitrogen
compounds that are converted to ammonium sulfate, (NH )2SO , under special
conditions of sample preparation. The sum of all nitrogen in a water
sample is equal to Kjeldahl nitrogen plus nitrite and nitrate nitrogen
concentrations.
VI
-------
Micrograms per gram (PG/G, yg/g) is a unit expressing the concen-
tration of a chemical element as the mass (micrograms) of the element
sorbed per unit mass (gram) of sediment. One microgram is one one-mil-
lionth of a gram.
Micrograms per liter (JJG/L, yg/L) is a unit expressing the concen-
tration of chemical constituents in solution as mass (micrograms) of the
solute per unit volume (liter) of water. One is equivalent to one milli-
gram per liter.
Milligrams per liter (MG/L, mg/L) is a unit for expressing the con-
centration of chemical constituents in solution as mass (milligrams) of
the solute per unit volume (liter) of water. One milligram is one one-
thousandth of a gram.
Organic nitrogen includes all nitrogenous organic compounds such as
amino acids, polypeptides, and proteins. It is present naturally in all
surface waters as a result of natural nitrogenous materials and biological
life in the watersheds and streams, but excessive concentrations may indi-
cate contamination from man-induced influences.
Orthophosphate is the most common ionized form of phosphorus in water
and the only one derived from natural sources. Orthophosphates comprise
the inorganic portion of phosphorous and include the three ionization
products of phosphoric acid H PO -1 , HPO -2 , and PO -3 in a water body,
whose relative concentrations are governed by the pH of the water.
Particle-size classification used in this report agrees with recom-
mendations made by the American Geophysical Union Subcommittee on Sediment
Terminology.
The classification is as follows:
Classification Size (mm) Method of analysis
Clay 0.00024 - 0.004 Sedimentation.
Silt .004 - .062 Sedimentation.
Sand .062 - 2.0 Sedimentation or
sieve.
Gravel .... 2.0 - 64.0 Sieve.
The particle-size distributions given in this report are not neces-
sarily representative of all particles in transport in the stream. Most of
the organic material is removed, and the sample is subjected to mechanical
and chemical dispersion before analysis in distilled water.
VII
-------
Pesticides are chemical compounds used to control undesirable plants
and animals. Major categories of pesticides include insecticides, miti-
cides, fungicides, herbicides, and rodenticides. Insecticides and herbi-
cides, which control insects and plants, respectively, are the two cate-
gories presented in this report.
Phosphorus is one of the major nutrients required for plant nutrition
and is essential for life. Phosphorous is not the sole cause of eutrophi-
cation of natural waters, but there is evidence that it is the key element
required by fresh-water plants and, generally, is present in the least
amount relative to need.
pH of water is a measure of the hydrogen ion concentration, or more
specifically, the hydrogen ion activity. It is most conveniently ex-
pressed in logarithmic units and represents the negative base-10 log of the
hydrogen-ion activity in moles per liter.
Polychlorinated biphenols (PCB) are industrial chemicals that are
mixtures of chlorinated biphenyl compounds having various percentages of
chlorine.
Polychlorinated napthalenes (PCN) are organochemical compounds simi-
lar to polychlorinated biphenols, except the basic unit of molecular
structure is napthalene instead of the biphenol complex.
Sediment is solid material that originates mostly from disintegrated
rocks and is transported by, suspended in, or deposited from water; it
includes chemical and biochemical precipitates and decomposed organic ma-
terial, such as humus. The quantity, characteristics, and cause of the
occurrence of sediment in streams are influenced by environmental factors
such as slope, length of slope, soil characteristics, land usage, and
quantity and intensity of precipitation.
Specific conductance is a measure of the ability of a water to conduct
an electrical current and is expressed in micromhos per centimeter at 25°C.
Because the specific conductance is related to the number and specific
chemical types of ions in solution, it can be used for approximating the
dissolved-solids content of water. Commonly, the concentration of dis-
solved solids (in milligrams per liter) is about 65 percent of the specific
conductance (in micromhos per centimeter at 25°C). This relation is not
constant from stream to stream, and it may even vary with time in the same
stream with changes in the composition of the water.
Streamflow is the volume of water and sediment that passes a given
point within a given period of time.
Suspended, recoverable is the amount of a given constituent that is
in solution after the part of a representative water/suspended-sediment
sample that is retained on a 0.45- ym membrane filter has been digested by
a method (usually using a dilute acid solution) that results in dissolution
of only readily soluble substances. Complete dissolution of all the par-
VIII
-------
ticulate matter is not achieved by the digestion treatment and, thus, the
determination represents something less than the "total" amount (that is,
less than 95 percent) of the constituent present in the sample. To achieve
comparability of analytical data, equivalent digestion procedures would be
required of all laboratories performing such analyses because different
digestion procedures are likely to produce different analytical results.
Determinations of "suspended, recoverable" constituents are made ei-
ther by analyzing portions of the material collected on the filter or, more
commonly, by arithmetic difference, between the determinations of (1)
total recoverable, and (2) dissolved concentrations of the constituent.
Suspended sediment is any particulate or colloidal material that is
maintained in suspension by the upward components of turbulent currents.
Suspended-sediment concentration is the instantaneous or velocity-
weighted concentration of suspended sediment in the sampled zone (from the
water surface to a point approximately 0.3 feet above the bed) expressed as
milligrams of dry sediment per liter of water-sediment mixture.
Suspended-sediment discharge (tons/day) is the quantity of sediment,
as measured by dry weight or volume, that passes a section of stream in a
given time. It is computed by multiplying discharge, in cubic feet per
second, times suspended-sediment concentration, in milligrams per liter,
times 0.0027.
Suspended, total is the total amount of a given constituent in the
part of a representative water/suspended-sediment sample that is retained
on a 0.45- ym membrane filter. This term is used only when the analytical
procedure assures measurement of at least 95 percent of the constituent
determined. A knowledge of the expected form of the constituent in the
sample, as well as the analytical methodology used, is required to deter-
mine when the results should be reported as "suspended, total."
Total organic carbon is an index of the concentration of dissolved-
and suspended-carbonaceous matter. High concentrations of organic matter
in an aquatic environment can influence the dissolved-oxygen balance. If
decomposable organic matter occurs in sufficient concentrations, intensive
bacterial activity can result in complete oxygen depletion.
Total, recoverable is the amount of a given constituent that is in
solution after a representative water/suspended-sediment sample has been
digested by a method (usually using a dilute acid solution) that results in
dissolution of only readily soluble substances. Complete dissolution of
all particulate matter is not achieved by the digestion treatment and,
thus, the determination represents something less than the "total" amount
(that is, less than 95 percent) of the constituent present in the dissolved
and suspended phases of the sample. To achieve comparability of analytical
data, equivalent digestion procedures would be required of all labora-
tories performing such analyses because different digestion procedures are
likely to produce different analytical results.
IX
-------
Turbidity of a water is the reduction of transparency due to the
presence of suspended-particulate matter. Such material may consist of
clay or silt, finely divided organic matter, or other microscopic organ-
isms which cause light to be scattered and absorbed rather than transmitted
in straight lines through the sample. One measurement of turbidity is the
Naphelometric Turbidity Unit (NTU).

WATER-QUALITY MONITORING OF THREE MAJOR
TRIBUTARIES TO THE CHESAPEAKE BAY
INTERIM DATA REPORT
By David J. Lang and David Grason
ABSTRACT
The U.S. Geological Survey is monitoring the water quality of three
major tributaries to Chesapeake Bay at their fall lines to obtain estimates
of constituent inputs potentially available to the bay. The monitoring
sites are: Susquehanna River at Conowingo, Md.; Potomac River at
Washington, D.C.; and James River at Cartersville, Va. Water-quality data
collected from October 1978 to April 1980 are presented in tables. Concen-
trations of major ions, nutrient and carbon species, metals, pesticides,
suspended sediment, and other selected constituents are presented for a
range of flows. The mean, standard deviation, minimum, maximum, and median
values for each constituent were determined by standard methods and are
presented for each sampling station. Bivariate linear regressions were
run for all constituents versus streamflow, specific conductance, and sus-
pended sediment. Those relationships exhibiting coefficients of determi-
nation (R ) greater than 0.50 are tabulated.
INTRODUCTION
The U.S. Environmental Protection Agency (EPA) has been directed by
the U.S. Congress (Senate Report No. 94-326) to conduct an in-depth study
of the environmental quality of Chesapeake Bay. As part of the EPA study,
the U.S. Geological Survey (USGS) is monitoring the water quality of the
three major tributaries to Chesapeake Baythe Susquehanna, Potomac, and
James Rivers (see fig. 1). Together, these rivers drain about 65 percent
of the land surface area contributing inflow to Chesapeake Bay.
The ultimate objectives of the project are to provide the following
water-quality information for the Susquehanna, Potomac, and James Rivers
regarding:
1. Estimated loadings of major ions, suspended sediment, and selected
nutrient species and trace metals.
2. Seasonal characterization of organic compounds, including selected
pesticides.
3. Error analysis and statements of other limitations inherent in the
information provided in the first two objectives.

This report is a compilation of water-quality data collected from
October 1978 to April 1980. It provides a base of information useful to
many investigators studying Chesapeake Bay and river-estuarine systems.
Load assessments and further data analysis will be presented in a final
report after completion of the data-collection phase in April 1981.
ACKNOWLEDGMENT
The authors are grateful to Mr. Howard Jarmon and his staff of the
Susquehanna Electric Co. for the cooperation and assistance received while
sampling at Conowingo Dam on the Susquehanna River.
HYDROLOGIC CONDITIONS
The three primary sampling sites are: Susquehanna River at Cono-
wingo, Md.; Potomac River at Chain Bridge at Washington, D.C.; and James
River at Cartersville, Va. As the monitoring points on the Potomac and
James Rivers are not located at the mouth of the rivers, the data at these
sites do not directly reflect constituent input to Chesapeake Bay. How-
ever, the data are representative of constituent concentrations and loads
that are potentially available to the bay.
Precipitation during the January 1979 to March 1980 period of data
collection was 19 to 41 percent above average (table 1) . Some areas
recorded in excess of 65 in. of rain in the 1979 calendar year. For the
same period, streamflows at the sampling stations were 12, 46, and 37
percent above the historical mean flows for the Susquehanna, Potomac and
James Rivers, as shown in the following table.

DATA COLLECTION AND PRESENTATION
Data-Collection Sites
Figure 1 shows the location of the water-quality monitoring stations
used in the study. The Susquehanna River station is at Conowingo Dam,
Conowingo, Md., where, if flow conditions permit, base-flow water quality
is measured every 2 weeks. The James River station is at Cartersville,
Va. , and the Potomac River site is at Chain Bridge at Washington, D.C.;
both are sampled monthly for base-flow water-quality constituents. The
USGS continuously monitors stage and flow at the Cartersville and
Conowingo sites. Potomac River flow is monitored at Little Falls, Md.,
half a mile upstream from Chain Bridge. Water samples analyzed for both
sediment and chemical quality are taken at high flows at all sites to
better understand the mechanisms that affect the water quality during
these critical periods of high mass transport.
Methods of Sample Collection and Analysis
All water-quality and suspended-sediment samples were collected by
USGS personnel by depth-integrating methods, as described by Guy and
Norman (1970). All water-quality samples were preserved in the field
according to methods described in the National Handbook of Recommended
Methods for Water Data Acquisition (U.S. Geological Survey, 1977) and
analyzed in the USGS Central Laboratory. Pesticide and organic carbon were
determined according to methods described by Goerlitz and Brown (1972) ,
and inorganic constituents were analyzed according to procedures cited by
Skougstad and others (1979). Sediment samples were analyzed in another
USGS laboratory, by methods described by Guy (1969).
Data Presentation
Simple bivariate linear regressions were run for all constituents
against discharge, specific conductance, and suspended sediment. The re-
gression line was fitted analytically by the method of least squares.
2
The coefficient of determination (R ) was then calculated for each
bivariate regression. This coefficient is a measure of the degree to which
the variance or square of the standard deviation is explained or accounted
for by the linear regression. The greater R is, the better the regression
line fits the observed data points, and the more highly correlated one
variable is to another. Table 2 contains a list of constituents whose
coefficients of determination are greater than 0.50 and are derived from at
least six data pairs. Coefficients of determination less than 0.50 were
not considered significant because, below this value, less than 50 percent
of the variation of the dependent variable is being explained by the
independent variable.

The data in table 2 demonstrate that there exists significant corre-
lations between chemical constituents for which data are available on an
infrequent, periodic basis, and streamflow, specific conductance, and sus-
pended sediment for which continuous or once daily data are available.
Along with continuous discharge record, these correlations can be used to
provide accurate estimates of constituent loadings.
Tables 3, 4, and 5 list the number of samples (n), maximum, minimum,
mean, median, and standard deviation for all parameters collected through
April 2, 1980.
A compilation of all water-quality data, except pesticides, for the
three stations is found in supplemental data A, B, and C. The data are
from the 1979 and 1980 water years.
Pesticide data collected in connection with the study are assembled
in supplemental data D. Atrazine and 2,4-D were the two constituents
detected most frequently; their concentrations were highest during summer
runoff.
Suspended-sediment concentrations and loads for the Potomac River at
Chain Bridge and the Susquehanna River at Conowingo are found in supple-
mental data E and F. Loads will not be tabulated for the James River
station until more suspended-sediment information is available.
Bottom material samples were collected approximately 1 mile down-
stream from Conowingo Dam on the Susquehanna River, on November 3, 1979.
Results of this analysis are found in supplemental data G.
