FOREWORD
The Environmental Protection Agency was established to coordinate adminis-
tration of the major Federal programs designed to protect the quality of our
environment.
An important part of the Agency's effort involves the search for information
about environmental problems, management techniques, and new technologies
through which optimum use of the nation's land and water resources can be
assured and the threat pollution poses to the welfare of the American people
can be minimized.
The Great Lakes National Program Office (GLNPO) of the U.S. EPA, was
established in Region V, Chicago to provide a specific focus on the water
quality concerns of the Great Lakes. GLNPO also provides funding and
personnel support to the International Joint Commission activities under
the U.S.- Canada Great Lakes Water Quality Agreement.
Several land use water quality studies have been funded to support the
pollution from Land Use Activities Reference Group (PLUARG) under the
Agreement to address specific objectives related to land use pollution to
the Great Lakes. This report describes some of the work supported by this
Office to carry out PLUARG study objectives.
We hope that the information and data contained herein will help planners
and managers of pollution control agencies make better decisions for
carrying forward their pollution control responsibilities.

PREFACE
The main thrust of this volume is to present a documentation of a 3-year
monitoring program designed to assess kinds and amounts of pollutants arising
from land drainage of mixed and predominantly single land uses in the Menomonee
River Watershed. Data are summarized on seasonal, annual and unit area bases
which include estimates of variances. Although numerous parameters were
determined, discussion is focused mainly on the principal parameters of concern
in the Watershed, i.e., suspended solids, total- and soluble-P and lead, to
illustrate behavior and magnitude of contaminants during runoff events, seasons
and years. Major factors affecting loadings of these key parameters are
indicated.
As part of this volume, data of the benthic macroinvertebrate surveys
are presented and evaluated in an attempt to establish a biological indicator
of pollution.

Abstract
The quality of runoff from nine mainstem river stations and three inner
harbor stations were monitored between 1975 and 1977. Automatic flow
recording and water sampling instruments were used at the mainstem river
stations. Seasonal flow and concentration data for 26 parameters monitored
throughout the study are documented, although discussion is focused on the key
parameters—suspended solids, total- and soluble-P and lead—to demonstrate
seasonal and site differences. Bacterial counts and PCB concentrations
determined sporadically are also included. Evaluation made on the
concentration data includes 1. comparison with water quality criteria, 2.
correlation to show relationships between parameters and 3. behavior of
parameter concentration and loading rates during an event.
Seasonal events and baseflow loads for four parameters estimated by a
stratified random sampling model enhanced by a ratio estimator are
presented. The most important hydraulic and land use activity factors
affecting variation in loading from one tributary area to another are
discussed. These factors either affect generated runoff or pollutant
concentrations. Remedial measures should be based on controlling land use
activities which result in high pollutant concentrations, and towards those
areas which because of such hydraulic characteristics as high connected
imperviousness, generate persistently high pollutant loadings.
Rainfall-runoff relationships and occurrence of first flush were also
analyzed.

1-1. INTRODUCTION
The river monitoring stations were established to determine the types
and amounts of water pollutants reaching the Menomonee River and its
principal tributaries. Emphasis was placed on the collection of samples
during runoff events. Because these stations are located on the mainstem
of the river they integrate drainage from all land use activities tributary
to that station. In contrast, Part II of this volume exhibits monitoring
data for drainage of areas in a predominantly single land use. In this way
it is possible to compare loadings for relatively large areas containing
mixed land uses while evaluating single land use impacts in those areas.
This volume deals only with a description of the monitoring activities and
the data found. Subsequent volumes (4, 5 and 6) will deal with the inter-
pretation of this data by various modeling and other methods.
The data outlined in Part I were collected during the period January
1975 to November 1977.

1-2. CONCLUSIONS
Mean seasonal ba'seflow and event flow and concentration values fluctuated
between seasons for each station and between stations during a season. The
trends in mean event concentrations between seasons for all stations, as
illustrated by the key parameters, reveal that 1. suspended solids levels were
highest in the summer, 2. the highest total-P concentrations were shared by
two of the seasons in any single year, 3. the soluble-P values were similar
for all seasons and 4. the chloride levels were always highest in the
spring. The mean event flows were highest in the spring for all stations in
any single year. The large size and multiple land uses characterizing each
tributary area normalized the mean event parameter concentrations between some
of the stations during a season. For example, total- and soluble-P
concentrations were similar at all stations during a season except at stations
413009 and 683002 which had concentration values affected by sewage treatment
plant discharges. The mean seasonal event suspended solids concentrations at
stations in the lower more urbanized part of the Menomonee River Watershed
were always higher than concentrations at stations in the less urbanized upper
watershed. Mean seasonal concentration of pollutants associated with
particulate matter were usually higher during runoff events than during
baseflow; soluble parameter levels were usually similar or lower during events
than during baseflow. The importance of non-point source contributions to the
level of particulate parameter in the river system is demonstrated clearly by
the relatively high mean concentration of suspended solids, total-P and lead
for events. Mean seasonal event concentrations of suspended solids were lower
in the inner harbor than in the river; total- and soluble-P concentrations
were similar in the two systems.
Bacterial counts were usually higher during events than baseflow.
Bacterial counts during events were usually lower at stations with
predominantly rural tributary areas.
Comparison of overall mean parameter concentrations with water quality
criteria indicate that the levels of lead, suspended solids, total-P and fecal
coliforms exceeded the acceptable levels for drinking water and/or freshwater
aquatic life.
A significant linear correlation was observed between suspended solids
and total-P concentrations at all stations during each season. The
significant correlation between suspended solids and total-P suggests that a
management strategy to control suspended solids also will reduce the input of
the pollutants associated with particulate matter. Metals—exemplified by
lead—are included in the group of parameters likely to be controlled by
management of suspended solids sources. In most cases, a positive linear
correlation was evident between flow and suspended solids but only occasional
significant correlation was observed for total-P and soluble parameters with
flow.
1-2
-------
The levels of suspended solids, total-P and lead always increased in the
rising stage of an event hydrograph as the overland flows produced washoff of
particulates. Soluble-P levels usually did not increase during events. The
variability in the concentration values for these parameters reveals that a
runoff event can only be characterized fully by sampling across the entire
hydrograph. The significant correlation observed between loading rates of all
the key parameters and flow during events suggest that flow is more important
to the determination of loading rate than concentration. The relationship of
concentration of the key parameters to flow and loading rate were less
predictable.
Seasonal event unit loadings varied between seasons for each station and
between stations during a season. The significant correlation observed
between seasonal parameter loadings and runoff (water loading) suggests that
the differences between seasons is largely accounted for by variation in the
amount of runoff. Changes in concentrations would account for any variability
in the relationship. Although the parameter and water unit event loading
values could be grouped into several ranges for each season, the most
urbanized station (413006) was usually amongst the group with the highest unit
loadings of water, suspended solids, total-P and lead and the least urbanized
station (673001) was usually amongst the group with the lowest loadings for
these parameters. The seasonal event loadings usually were a significant
portion of the total seasonal loadings (event plus baseflow); event
contributions accounted for a greater proportion of the total annual loadings
of suspended solids and total-P than point sources. Considerable amounts of
the event loadings in the Watershed for 1976 and 1977 were contributed by
three and two big events, respectively.
In order to develop non-point source remedial measures for the mainstem
river stations, it is important to identify factors responsible for
accelerating the pollutant loadings in the tributary areas. The factors
affecting loading are hydraulic factors which determine the amount of runoff
and the land use activities that affect pollutant concentrations. The
hydraulic factor most manageable and important in urban areas is the degree of
connected iinperviousness area in a tributary area. Water, suspended solids
and total-P seasonal unit event loadings were significantly correlated to
degree of conrected imperviouness area in 1977. The storm sewered station
with the highest degree of connected imperviousness (413006) usually generated
the highest amount of runoff and unit loading values of suspended solids. The
station with natural drainage and the lowest percent connected imperviousness
(673001) usually generated the lowest amount of runoff and suspended solids
loadings. Variability in the relationship between loading and connected
imperviousness was due to other hydraulic factors affecting the large amounts
of pervious area in each tributary area. Temporary land use activities such
as construction and road salting and long term activities such as heavy
vehicular traffic and industrialization affect the amount of pollutant
material available for transport. Although the most critical land use/land
activities could not be isolated from the mixed land uses present in the
tributary areas, the stations with more urbanized land uses usually had higher
loadings of suspended solids and lead. Remedial measures should be based on
controlling land use activities which result in high pollutant concentrations
and towards those areas, which because of their hydraulic characteristics like
1-3
-------
high degree of connected impervious area, generate persistently high pollutant
loadings.
Analysis of rainfall-runoff relationships indicates that runoff was not
significantly correlated with rainfall except at the station (413006) with a
high degree of connected impervious-area. The percent of runoff did not
necessarily increase in seasons with large amounts of rainfall. The impact of
the amount of rainfall on this percentage of runoff is modified by the effect
of factors such as evapotransporation.
The occurrence of first flush during events was observed but was not
consistent.

Site Selection
Selection of the mainstem river monitoring sites was guided primarily
by distribution of land uses in the Menomonee River Watershed and the loca-
tion of tributary/mainstein confluences. Sites were also selected to charac-
terize water quality in the inner Milwaukee Harbor. Land use in the
Watershed can best be delineated as an industrial-commercial complex in the
lower quarter, a low to medium density residential section in the center half
and an area of transition from rural to urban land use in the upper quarter.
Land use distribution monitored at each of the automatic sampling sites is
shown in Table 1-1. Principal river tributary sites were established to
divide the total Watershed into more manageable proportions and to allow
direct loading comparisons between these subwatersheds and the Watershed as
a whole. Further comparisons were obtained between the mixed land use areas
tributary to the mainstem stations and the drainage from the predominantly
single land use sites (1). To calculate land use distribution directly
adjacent to a sampling site it is necessary to examine the footnotes to
Table 1-1. Other land use information can be found (2).
In total, nine automatic sampling stations were established on the
mainstem and principal tributaries of the Menomonee River and three grab-
sampling sites (413014,- 413013, 413012) were located in the inner Milwaukee
Harbor area. The sites were numbered according to the format used for the
U.S. EPA STORET data base (Fig. 1-1).
Principal criteria used to locate a sampling site were: 1. Availability
of a suitable construction area close enough to the stream, 2. suitability of
the stream channel for accurate measurement of flow and representative sampling
for water quality and 3. ease of accessibility. Permission (private and
governmental) to construct the stations at the chosen sites was obtained
between June and October 1974.
The grab sampling stations in the inner Harbor area were located at
bridges.
Sampling Equipment
Sampling equipment was housed in stone, brick or aluminum shelters of
approximately 3 x 3 m dimensions. The stations were constructed by the U.S,
Geological Survey (USGS) and an example of a shelter is shown in Fig. 1-2
and the flow and water sampling equipment in Fig. 1-3. Each shelter was

heated in winter and furnished with electrical power.
The USGS-designed PS-69 water sampler—manufactured by the St. Anthony
Falls Hydraulics Laboratory—was installed at each location. Power was
provided either from 3 x 12 volt automobile batteries, wired in series, or
from the DC output of a transformer. An impeller pump served to draw water
samples through a 2-cm plastic and copper intake line positioned 15 cm
above the river bed. Height of the intake corresponded to average water
depth during summer baseflow periods. The inlet—positioned perpendicular
to the direction of flow—was placed in the center one-third of the stream.
If the intake line on the sampler was clogged, a blown fuse curtailed
further sampling. At some stations clogging of the inlet with filamentous
algae or other debris was fairly frequent in the early stages but the problem
was later alleviated by angling the intake pipe at about 45°. A rotating
arm on the sampler distributed the water to 72 wide-mouthed, 1-L polypropylene
bottles.
Stage height of the stream was measured using manometers manufactured by
Scientific Instruments and recorded on a digital tape recorder (Fisher
Porter); samples were collected at hourly intervals and marked on the tape
recorder. Stations 413005, 413006, 413007 and 683001 utilized a Stevens
Recorder that traced the shape and size of the hydrograph on a stage chart.
Dissolved oxygen and temperature were measured during baseflow with a
Yellow Springs Instrument Co. dissolved oxygen meter.
Five of the mainstem monitoring sites (673001, 683001, 413008, 413005
and 413004) were equipped with Hydrolab continuous monitoring meters which
recorded pH, conductivity, dissolved oxygen and temperature. The equipment
consisted of electrodes housed in a protective plastic casing, a data
scanner capable of separating data impulses and a strip chart recorder. The
system was powered by a 12-volt automobile battery and internal mercury
batteries. Depending on conditions the probes were calibrated once or
twice a week. The strip charts were digitized and stored on computer
magnetic tapes for further analysis.
Grab samples at the inner harbor stations were obtained with 1-L
Kemmerer bottles.
Sampling Procedures
The objectives of the project dictated that emphasis on sampling be
placed on runoff events since baseflow loadings comprise only a small
fraction of the total tributary loadings to Lake Michigan. During the
course of runoff event sampling, collections were made to delineate the
entire hydrograph and its corresponding pollutograph.
Initiation of sampling occurred at station 413005 in June 1975, stations
683001, 413006 and 413009 were completed for sampling in spring 1976, and
the remainder were ready for sample collection in spring 1977. Sampling
dates and parameters measured are shown in Tables 1-2 and 1-3 for 1976 and

1977, respectively. For comparative purposes, event samples were collected
at predominantly single land use sites in 1976 and 1977 (1).
During the course of an event, samples (700 ml) were collected at hourly
intervals until the stage dropped below the original triggering height or the
sampler was manually turned off. Samples were removed during or as quickly as
possible after the event terminated. Depending on the size of the event,
five or more samples were selected for analysis; larger sample numbers were
selected during the period of spring runoff. Selection was based on observa-
tion of the field-drawn hydrographs and samples were chosen on the rising,
peak and falling stages of the hydrographs. Actual time of sampling was
recorded on digital tape.
For transport to the laboratory for analysis, the samples were placed in
narrow-mouthed polypropylene bottles and mailed immediately or stored in a
frozen condition (Wisconsin Department of Natural Resources Southeastern
Office). All samples were mailed in styrofoam containers (4 samples each)
fitted with an ice compartment. The wide-mouthed bottles used in the
automatic samplers were replaced after washing in phosphorus-free detergent
and rinsing with distilled water.
Periodic sampling during non-event stages were conducted at each mainstem
location. In 1975, sampling was scheduled 1. at 2-week intervals during
January through March; 2. twice a week in April through June; and 3. once a
week July through December. In 1976 baseflow was surveyed on a weekly basis
from January through March and every two weeks between April and December.
All baseflow samples collected in 1977 were obtained on a monthly schedule.
Confusion sometimes occurred between event and non-event surveys during
periods of high spring runoff. Transportation and storage of non-event
samples corresponded to the procedures described for event sampling.
Furthermore, two grab samples were collected at one station (chosen randomly)
during each non-event sampling collection. The grab samples were obtained
very close to the inlet of the samplers. These samples provided some quality
control information on such factors as sample storage effects, river homoge-
neity and differences between sampling methods. For comparison with event
samples, in situ measurements of dissolved oxygen, conductivity and tempera-
ture were obtained during each survey.
Grab samples in the inner harbor area were collected during and between
runoff events. The days chosen for this sampling usually were not determined
by flow conditions and consequently the majority of samples were obtained
between events. In 1975, the harbor sites were surveyed every 2 weeks from
January through March and July through December and each week from April
through June. In 1976, the survey was conducted every 2 weeks while an
irregular schedule was maintained in 1977; spring and summer sampling in 1977
occurred at approximately monthly intervals. Samples were obtained with a 1-L
Kemmerer bottle lowered from a bridge. The water was sampled at the surface,
at approximately mid-depth and at about 1.5 m from the bottom; dissolved oxygen,
conductivity and temperature were determined by in situ methods at each depth.
All samples were transported and stored by the procedures described earlier.
Effluent samples were collected for water quality analysis at the
1-12
-------
Germantown Waste Treatment Facility on September 18, 1975 and July 13, 1976
and at the Parkside and Parkview Facilities of the City of Menomonee Falls
on June 19 and 25, 1975 and on September 1, 1976. At each survey, 24-hr
composite samples were collected and analyzed.
Laboratory Analysis
A listing of the water quality parameters determined on Menomonee River
samples is shown in Table 1-4. With the exception of hardness, alkalinity
and total organic carbon, all group A parameters were determined on most of
the event and non-event samples. The other groups of parameters were
analyzed less frequently. For the bacterial parameters (group B), analysis
was conducted on small grab samples. When pesticides (group D) were
scheduled for determination, large grab samples were collected and stored in
glass bottles. Group C parameters were determined on the automatically-
collected samples but were transported and stored in bottles separate from
the group A samples.
All analyses were conducted at the Wisconsin State Hygiene Laboratory
located at the University of Wisconsin-Madison some 130 km from the sampling
sites. Those parameters likely to undergo rapid transformation (e.g.,
inorganic nitrogenous forms) were analyzed within 24 hr after arrival at the
Hygiene Laboratory. To prevent overloading of the analytical capability,
some samples were held in a frozen condition in Milwaukee until it was
convenient to receive them in Madison.
Analytical procedures used for the analysis of nitrogen and phosphorus
forms, total organic carbon, metals and phenols were those recommended by
the U.S. EPA (3). Nitrogen and phosphorus forms were determined by
approved autoanalyzer techniques (3). Digestion of samples for metal
analysis was described in (3) and atomic absorption spectroscopy utilizing
a graphite furnace was—in most cases—the chosen method of determination.
Flame atomic absorption spectroscopy was used for determination of magnesium,
zinc and iron. Alkalinity hardness, total-, suspended- and volatile
suspended-solids; chloride; and the group B parameters were analyzed by
methods described in (4). Group D parameters, except phenols, were analyzed
by methods contained in the Federal Register (5).
The data were filed in the STORET data base and in the WDNR computer
mass storage files for reporting and statistical analysis.
Methods for Calculating Loadings
The term "hazardous land use" is relative, being defined as a land use
from which significantly greater amounts of a pollutant are derived. It is
possible to calculate pollutant from land use activities in a number of
ways; however, it must be kept in mind that the goal is to be able to

statistically compare loading values. Consequently, the method of calculating
loads should 1. be consistent with the assumptions associated with the
sampling schemes that were used, and 2. be capable of estimating the variance
associated with each load (to permit a statistical comparison).
Initially, loads for the Menomonee River Watershed were calculated
using an "integration" method whereby loading values were possible only for
events for which concentration data were available. This "model" linearly
interpolated between measured concentration data points in order to assign a
concentration for each measured instantaneous flow. For events during which
extensive concentration information is available, this interpolation routine
can be a reasonable approximation of concentration variation with time. For
events with limited concentration information, the interpolation routine can
introduce unsystematic (and unquantifiable) variation. The integration
method does not produce loads for events for which flow information is
available, but concentration information is not; and it does not produce any
estimate of the variation associated with the loads it produces.
A stratified random sampling model enhanced by a ratio estimator has
been described for pollutant loading calculations at the monitoring stations
(6). The assumptions of the model are: 1. Simple random sampling of water
quality within nonoverlapping subpopulations or strata is possible and
2. supplemental flow information is available rather than instantaneous flow
values taken only at those times when water quality samples were taken. This
model meets the goal stated above in that it produces load and variance
estimates for each stratum and for the sum of the strata.
The technique of stratifying subsample data is used because it provides
a means of gaining precision in estimates by clustering homogeneous units
(periods of like concentrations). The overriding assumption of this
technique is that a better estimate of what is occurring in the population
can be gained by observing subpopulation characteristics rather than by
sampling from the population as a whole. The procedure for the stratified
random sampling model consists of the following stages: 1. Division of a
heterogeneous population into strata, each of which is internally homogeneous
(to the extent that each stratum is homogeneous, a precise estimate of the
pollutant load can be made); 2. the selection of a random sample from each
stratum; and 3. the consolidation of the strata statistics into a combined
statistic weighted for size of strata.
Since water quality samples were gathered without regard for strata,
the selection of strata in the application of this model is particularly
critical. Two general criteria must be met in this selection: 1. Subsamples
within a stratum must have had equal probability of being chosen (subsamples
gathered under different collection frequencies must not be in the same
stratum); and 2. homogeneous units can be determined after examination of the
subsample data, but must not be tailored to each data point (i.e., a
generally applicable set of rules for inclusion in a stratum should be
developed).
The process used to apply the stratified random sampling model to water

-------
quality data collected in 1976 as part of the Menomonee River project is
described. This example serves to acquaint interested researchers with an
acceptable method to calculate pollutant loads.
At all stations, water quality samples were collected systematically
during all event times during which automatic samplers were functioning. At
those stations which had flow during non-event periods, samples were collected
for those periods on an irregular schedule. Continuous flow monitoring data
were collected for all stations for the year. Concurrently, continuous
rainfall monitoring data were collected at sites throughout the Watershed.
First, determine if the assumption of random sampling within a stratum
dictates that certain data should not be grouped together. For the
Menomonee River stations where water qiality was systematically sampled during
events and irregularly during non-events, two strata were dictated by the
assumptions of the model. Other sampling situations that could result in
data not being grouped within a stratum include changing the sampling
frequency on an automatic sampler, or changing the schedule for the collection
of non-event samples.
For the Menomonee River project, estimated loadings were compared on an
annual basis, between seasons at a station, and within a season at all
stations. As a result, seasonal loads were estimated. While the initial
reason for this move was to be able to compare estimated loadings for
seasons, the resulting partition separated the water quality concentration
data points on the basis of storm type, stage of vegetation and other seasonal
factors which may or may not be related to observed concentrations. At
stations for which non-event water quality was sampled, eight strata were
defined for 1976, i.e., event and non-event data for each of four seasons.
For stations at which only event water quality was sampled, four strata were
defined.
Having satisfied the key assumptions of the model, any additional strata
are designated for the purpose of calculating a more precise estimate of
load (i.e., for minimizing the variance associated with a load estimate). To
accomplish this, similar concentrations are grouped within the same stratum
after previewing the concentration data plotted against time, instantaneous
flow, rainfall intensity, or any other factor related to concentration.
In an attempt to reduce the variance associated with the estimated
seasonal loading (and the estimated annual loading), the concentration data
were previewed for each season at each station. Concentration changes with
time and concentration against instantaneous flow were plotted in order to
gain insight into the factor(s) accounting for observed variability in the
concentration data. Observing concentration variations with time permits
the examination of hydrograph positional effects, i.e., concentration
variations between ascending and descending portions of the hydrograph (e.g.,
the first flush effect). Viewing plots of concentration versus instantaneous
flow permits the examination of a correlation between flow and concentration;
higher concentrations occurring primarily with higher flow, or, conversely,
higher concentrations occurring primarily with lower flows.
1-16
-------
If the ascending compared with the descending limb of the hydrograph was
adopted as a rule for further stratification for one or more seasons, all
times during which events were identified would have to be assigned to either
the ascending stratum or the descending stratum. A complication arose in
this regard. During events with multiple peaks, observed concentrations
fluctuated in an apparently unsystematic fashion. Occasionally each of the
multiple peaks evidenced a first flush. In other instances only one peak
displayed this effect. This inconsistency makes assigning all time during
the season a difficult, if not unsupportable, proposal. In addition, a
comparison of stratification on the basis of ascending versus descending
limb (for one event for which extensive concentration data were available)
to stratification on the basis of flow showed no difference in either the
estimated load or the variance associated with the estimate. For these
reasons, stratification on the basis of a flow rule was chosen over stratifi-
cation on ascending versus descending limb of the hydrograph.
Underlying stratification on the basis of flow is the assumption that
relatively similar concentrations are observed with similar flows. Central
to this process is the determination of the flow cutoff rule. For the
Menomonee project, two general types of flow cutoff rules were investigated:
1. For each event hydrograph a flow cutoff is chosen, and 2. for each season
a flow cutoff is chosen. An event based cutoff rule groups concentrations
across events on the basis of the instantaneous flow when the water quality
sample was collected. This implies that concentrations observed during event
times when flow is higher than the cutoff would be expected to be similar
not only within each event, but also across events. Setting a flow cutoff
for events during which water quality samples were collected is obviously
more straightforward than setting a cutoff for events during which no samples
were collected. Again, a general rule must be established in order to
accomplish this task (e.g., a cutoff flow of 1. 0.5 (event peak flow),
2. 0.5 (event initial flow and event peak flow), or 3. [peak flow-(event
peak flow-event initial flow)]. A seasonal flow cutoff rule also groups
concentrations on the basis of the instantaneous flow when the water quality
sample was collected; however, there is one cutoff flow which determines the
assignment of concentration data points to strata for an entire season.
Visual inspection of the plots of concentration against flow for a
season and concentration with time for a season did not provide information
by which either of the two general types of flow cutoffs could be chosen.
Load estimates calculated using different specific rules for each of the
general flow cutoff types were compared for a series of events for which
extensive concentration data were available. There was no trend in the
variance estimates which favored one general type of flow cutoff rule over
the other.
The next consideration in choosing the general type of flow cutoff is
the ease of application of the method. For the event based cutoff rule for
events during which many water quality samples were collected across the
hydrograph, choosing a reasonable cutoff flow is straightforward. With few
water quality samples for an event or with a poor distribution of water
quality samples across the hydrograph, the choice of a cutoff flow becomes
1-17
-------
difficult. However, in order to arrive at a general rule to apply to event
times for which flow information is available but water quality data is not,
enough event hydrographs must be examined for each season to be able to
characterize what is being observed in terms of flow versus concentration for
an event. To the extent that this characterization of events is possible,
a reasonable general rule can be determined. If a good characterization is
not possible, then it is not possible to determine a general rule for
stratification. For the seasonal cutoff flow rule, the assumption is that
higher concentrations are associated with similar flows (high or low) for
the season under consideration. From an additional examination of the plot
of concentration versus instantaneous flow, good candidates for the seasonal
cutoff flow can be determined. For the Menomonee River Project the seasonal
cutoff flow approach was chosen over the event based cutoff flow for two
reasons: 1. The two methods were indistinguishable on the basis of
estimated load or variance for test data, and 2. the application of the
seasonal cutoff flow approach is more straightforward.
For the purposes of further illustrating the process of choosing a
cutoff flow for stratification, Figs. 1-4 and 1-5 are included. Each
figure includes a plot of suspended solids concentration versus the
instantaneous flow at the time when the water quality sample was collected,
and a plot of instantaneous discharge and suspended solids concentration
with time. All plots are for the time period March 26, 1976 to June 1, 1976.
No single cutoff flow is obvious.
To investigate the effect of different cutoff flows on the estimated
load and its associated variance, loads were calculated using several
stratification schemes. A one stratum scheme was used as a baseline. Four
different two strata schemes were used for each of the two stations repre-
sented by Figs. 1-4 and 1-5. Flow cutoffs were chosen to represent an
approximate range of 5 to 30% of the peak flow for the season. For the
stations and season represented by Figs. 1-4 and 1-5, estimated loads and
variances (actually the square root of the mean squared error, which is
an estimate of the standard deviation) in kg/ha of suspended solids for the
stratification schemes are shown in Table 1-5.
While the size of the variance term is the sole criterion with which to
judge which of several estimated loadings is the most precise, an additional
factor must be taken into account before a final choice is made. The
additional factor that must be considered is the degrees of freedom (df)
associated with an estimated load, which is important in statistical
comparisons. Generally, with more df, a more sensitive comparison can be
made. However, the rate of increase in sensitivity with more df from 1 to
15 df is much greater than from 15 to 120 df. Consequently, if estimates
having greater than 15 df are compared, it is generally safe to choose on
the basis of the smallest associated variance. If, on the other hand, the
estimates have < 15 df associated variances that vary and a Student's t—
distribution table should be referenced in order to assess the increase in
sensitivity traded for a greater variance.
For the estimated loadings and variances located above, all df were

Methodological notes
1. For the Menomonee River Watershed normalized loads (kg/ha) were
desired. To get the variance associated with a normalized load,
divide the square root of the mean squared error (standard
deviation) by the same number that the load was divided by to
normalize it.
2. Individual strata characteristics (i.e., the estimated load,
variance, and df) can be combined to estimate loads, etc., for
longer time periods; however, this combination is ordinarily not a
simple summing and should, therefore, be done according to the
accepted procedure (6).
To apply the stratified random sampling model in other watersheds (and
for other parameters) after water quality samples have been collected without
regard for strata, the following process should be used:
1. Determine what strata need to be designated on the basis of either
the random sampling (within a stratum) assumption or the need for
estimated loads for particular time periods.
2. Plot the concentration data for each period of interest versus
instantaneous flow, with time (superimposed on the hydrographs
for that period), and any other way considered informative in
understanding the variation in concentration.
3. Examine the plots in order to determine whether concentrations vary
more within an event (which would imply an event related stratifica-
tion scheme, such as ascending versus descending hydrograph, or an
event based cutoff flow) or from event to event (which would imply
a seasonal cutoff flow.
4. Evaluate which general stratification scheme seems most appropriate
given the amount of concentration data available and initial test
results.
5. Calculate test loads and variances to determine which stratification
scheme gives the most precise load, within the constraints listed
for degrees of freedom.

Key Parameters
Two major types of pollution arising from nonpoint sources have been
identified in the Great Lakes Basin, namely, nutrients and sediments which
accelerate eutrophication of lakes and toxic materials which constitute a
public health hazard and a hazard to the biological communities. The basic
guidelines used in selecting key parameters for these types of pollution
are 1. the pollutant must be present in significant amounts in the watershed
and 2. it must be amenable to remedial control measures. The key parameters
selected include suspended sediment; total phosphorus; toxic metals,
primarily Pb, Cd, Cu, Zn; toxic organic materials, principally pesticides,
PCBs and phenols; and fecal coliforms.
The parameters deemed to be of greatest importance in the Menomonee
River Watershed are suspended sediment, total phosphorus and lead. Discus-
sion of results will be focused primarily on these parameters.

1-4. RESULTS AND DISCUSSION
Flow and Concentration
Seasonal flow and concentration
Concentrations of the 26 parameters were monitored during runoff events
and during baseflow (non-events) at the 12 malnstem river stations. The
monitoring stations included nine automatic and three harbor grab sampling
sites. Flow was recorded continuously at the automatic stations. Monitoring
of flow and parameter concentrations was begun in 1975 and continued through
the fall of 1977. The concentration data were compiled and stored in the
U.S. EPA STORET system. Flow records were maintained on computer tape and
are available from the WDNR. From 1975 to 1977 mean daily and monthly flow
values were tabulated for each station in the U.S. Geological Survey Water
Data Reports for Wisconsin (7-9).
Seasonal mean flows during events and baseflow at the automatic stations
and the concentrations of 24 parameters at each of the 12 mainstem stations
are presented in the Appendix (Tables I-A-1 to I-A-36). Data for temperature
and pH was obtained during baseflow but is not tabulated in this report.
Mean seasonal temperature during baseflow ranged from 0.3 to 9°C in winter
and 19 to 23°C in summer; pH during the total period of observation ranged
from 7.1 to 8.5. Concentration data presented in the tables include the
number of samples (frequency) used in the calculation of the seasonal mean
values and the standard deviation for each mean.
Seasons were defined as follows:
Summer - was the period from June 1 to September 30 of each year.
Fall - was the period from October 1 to December 21 of each year.
Winter - was the period from December 22 to the onset of spring.
Spring - was initiated by observing the onset of sustained high flows and
varied from year to year and between stations in a particular year.
Ranges of dates for the onset of spring were March 14 to March 20
in 1975, February 2 to February 17 in 1976 and February 22 to
March 21 in 1977 and always terminated on May 31 of each year.
Concentration data at the automatic sampling stations and at the harbor
grab sampling sites are discussed separately because of the differences in
sampling techniques and the presence of lake effects (seiche) in the harbor.
For illustrative purposes the key parameters—suspended solids, total-P,
soluble-P and lead—are emphasized to show seasonal and site differences.
1-24
-------
Automatic sampling stations
Seasonal mean event flow values were most often highest in spring. High
spring flows may exert a significant impact on total water loading but this
impact may be normalized by taking into account the number of event days.
For example, in 1977 mean spring flows were higher than mean summer flows
even though twice the number of event days were observed in summer.
Mean concentrations of suspended solids during events were usually
highest in the summer. Except in 1977, lowest concentrations occurred in
the fall; trends in 1977 were ill-defined because only a few samples were
collected. For the entire study period high concentrations of total P
occurred during at least two seasons and summer was always one of the
seasons involved. For 1975 and 1976 comparable concentrations of total P
were found in summer and fall. In 1977 these comparable concentrations
occurred in summer and spring. High concentrations of soluble P were not
observed consistently in any single season. Seasonal trends for lead are
difficult to assess because only limited numbers of samples were analyzed.
With the exception of station 673001, chloride concentrations were always
high in spring because of road salt use in the winter; land uses tributary
to station 673001 are largely rural. Unlike total- and soluble-P, high
concentrations of suspended solids occurred only in summer. Because the
peak of construction activities occurs during the summer it is probably
of particular importance to provide sediment control measures during summer
when high intensity rains are prevalent. The significance of the high summer
concentrations of suspended solids is elaborated upon in the section dealing
with loading data.
During events, parameter concentrations differed between stations during
a particular season and for all seasons. However, similarities in mean
concentrations exist at some stations as illustrated by the key parameters,
thereby allowing ranking of the stations into low, intermediate and high
flow or concentration groupings. Differences in flows between stations may
contribute to variations in parameter concentrations. High mean seasonal
flow values were usually observed at stations with large tributary areas.
In general these stations exhibited low concentrations of suspended sediments.
The relative pollutant concentration from each tributary area in the water-
shed is elucidated further in the discussion of loading data. At the three
stations (673001, 683002 and 683001) located in the upper part of the water-
shed, low concentrations (based on mean values) of suspended solids were
observed during all seasons. For all seasons, high concentrations of sus-
pended solids were encountered at stations 413008, 413007 and 413006.
Low concentrations of total- and soluble-P were observed at all stations
except 413009 and 683002. Total- and soluble-P concentrations were highest
at station 413009 regardless of season. These high P levels can be
attributed to the combined sewered area monitored at this station. Inter-
mediate concentrations of total- and soluble-P were encountered usually at
station 683002. These relatively high peak concentrations may reflect the
impact of two sewerage treatment plants discharging above the station.
1-25
-------
The mean Pb concentrations for all seasons were highest at stations
413007 and 413009, i.e., the more urbanized areas of the watershed. The
lower concentrations were encountered at those stations tributary to the
more rural areas. During periods of runoff, urban sources of suspended
solids and lead appear to have a greater impact on the water quality of the
river than do rural sources. Non point sources of total- and soluble-P—in
urban and rural settings—appear to have minimal impact on concentrations of
total- and soluble-P in the river.
Seasonal concentrations of parameters associated with particulate
matter were usually higher during runoff events than during baseflow.
This trend as exemplified by suspended solids, total-P and lead also
occurred at all stations except at 673001 and 413006 for suspended solids
and 683001 for total-P; at these three stations concentrations of these
parameters were similar for events and baseflows. The importance of the
non-point source contribution to the levels of particulate parameters in
the river system is demonstrated clearly by the relatively high concentra-
tions of suspended solids, total-P and lead during events.
In contrast, seasonal event concentrations of soluble parameters were
either lower or similar to those observed during baseflow. At some stations-
particularly 683001, 413005 and 413004—the baseflow concentrations of
soluble-P were higher. High baseflow concentrations of soluble parameters
may indicate point source contributions as shown by high soluble-P and
ammonium-N concentrations at station 683001. This station is immediately
downstream from the sewerage treatment plant in Menomonee Falls.
Inner harbor stations
Stations in the inner harbor include 413014 and 413013 located in the
Menomonee River portion of the inner harbor which starts at the dam below
Falk Corporation and ends at 2nd Street. Station 413012 lies just below
the confluence of the Menomonee and Milwaukee Rivers.
Concentration data from the inner harbor stations provide an indication
of water quality in the mixing zone between the Menomonee River and
Lake Michigan. The inner harbor has a mean depth of 6 m and width of 60 m.
Rapid mixing of the river and lake waters is restricted by a breakwater
across the entrance of the harbor. A seiche effect has been evidenced at
each of the inner harbor stations.
For most of the parameters during events, no consistent patterns in
concentrations emerged between seasons. The mean event concentrations of
suspended solids, total- and soluble-P for all seasons were similar at the
three stations although variability was observed during some individual
seasons. High concentrations of chlorides occurred in the spring and fall.
Parameters associated with particulate matter were always higher during
events than during baseflow as evidenced by analysis of samples at the
1-26
-------
automatic stations. Overall, concentrations of soluble parameters were
the same during events and baseflow. The baseflow levels of dissolved
oxygen were much lower than levels during events in the summer and Fall, The
dissolved oxygen dropped to levels considered critical for most fish species.
Comparison of concentration data showed that the mean event concentra-
tions of suspended solids, total- and soluble-P and lead in the inner harbor
for all seasons were higher than the levels observed in the nearshore zone
of Lake Michigan (10). Mean seasonal concentrations of suspended solids
during events were lower in the inner harbor than in the river; total- and
soluble-P concentrations were similar in the two systems. Lead concentrations
in the inner harbor were between the low concentrations found at the more
rural stations and the high concentrations in the urbanized settings.
Bacteriological and organic pollutants
Bacterial counts were determined during baseflow events and runoff
events at the automatic mainstem stations (Table I-A-37 and I-A-38). One
grab sample was collected during three events and during baseflow for most
of the stations. Even though there were only a limited number of samples
examined the bacterial counts during events were always much higher than
during baseflow. During events, bacterial counts usually were lowest at
the predominantly rural stations (673001, 683002, 683001 and 413008). The
fecal coliform:fecal streptococcus ratio was usually less than four at all
stations. The ratio indicated that human wastes were not an important
source of bacteria in the Watershed.
Organochlorine insecticides and PCBs were scanned during one event and
two baseflow surveys. Concentrations were below detection limits in all
samples.
Comparison of runoff and baseflow
quality with water quality criteria
The overall mean values of event and baseflow concentrations of selected
parameters at stations 413006 and 413005 were compared to water quality
criteria (Table I-A-39). The stations selected for such evaluation were
considered representative of urban land uses. The water quality criteria (11,
12 ) specify concentrations of contaminants that—if not exceeded—result in
an aquatic ecosystem suitable for higher uses of the water. The criteria
levels for domestic water supply incorporate the available data for human
health protection. The criteria for freshwater aquatic life were chosen to
offer a degree of safety for survival of fathead minnows in the Menomonee
River. The metal values used for the water quality criteria represent
soluble forms and are not directly comparable to the total metal concentra-
tions determined at the mainstem stations. Usually, only a small percentage
of the total metal is in soluble forms.
A potential exists for lead levels to exceed drinking water criteria,
1-27
-------
but not levels considered potentially hazardous to fathead minnows. The mean
event concentrations of the other key parameters (suspended solids, total-P,
and fecal coliform) exceeded acceptable levels for drinking water and/or fresh-
water aquatic life. The extremely high event fecal coliform counts especially
demonstrated the potential impact of runoff events on the water quality of
urban rivers.
Parameter concentration relationships
Correlation matrices relating flow, suspended solids, total- and
soluble-P and chloride were determined at eight of the automatic mainstem
stations for the spring and summer of 1977 (Table I-A-40). These seasons
were represented by a relatively high number of samples, but lead was not
among the parameters frequently analyzed. All the samples were collected
during runoff events. A strong linear correlation was indicated between two
parameters if the correlation coefficients were significant at probability
levels of 0.05 or 0.01.
In most cases, a positive linear correlation was evident between flow
and suspended solids. Only occasionally did significant correlations
exist between total-P and flow. The soluble parameters—soluble-P and
chloride—exhibited either low or negative correlations with flow. Negative
relationships were observed more often between chloride and flow. The
relationship between the parametersand flows was also observed in plots of
the same seasonal data from stations 413006 and 413005 (Figs. I-A-1 to
I-A-4). xhe plots also indicate that significant linear correlations exist
between flow and some of the parameters at both stations. However, the
significance of the correlation coefficient for suspended solids and total-
P appear to depend upon the relatively low variability in the concentrations
at lower flow values. A relatively high variability in concentrations at
higher flows was less of a factor in the correlation coefficient, because
most of the data points were in lower flow ranges. A similar problem was
revealed in the flow to chloride correlations except the chloride concentra-
tions demonstrated less variability in the high flows and when plots of
concentrations and flow data used in the correlation analysis were made at
stations 413006 and 413005, the same relationships existed (Figs. I-A-1 to
I-A-4). However, the high correlation coefficients for suspended solids
and total-P with flow appear to depend upon the relatively small variability
in concentrations in the low flow ranges. Although large variability in
concentrations occurred at higher flows it was less of a factor in determin-
ing the correlation coefficient, because most of the data points were in
the lower flow ranges. A similar situation was evident for the chloride
and flow correlations except that the chloride concentrations exhibited less
variability at higher flows. The correlation coefficients would have more
accurately described the relationship between the parameters and flow if the
concentration data had been separated into two strata based on flow. The
variability of the concentration values indicates the difficulty of using
flow to predict concentrations of pollutants associated with particulates
at higher flows and concentrations of some soluble parameters at low flows.
1-28
-------
A highly significant linear correlation was observed between suspended
solids and total-P concentrations at all stations during each season (Table
I-A-40). The significant linear correlations between suspended solids and
total-P values at all the stations indicate that a management strategy to
control suspended solids will also reduce input of theparameters associated
with the particulates. Metals such as lead would be included in the group
of parameters likely to be controlled by management of suspended solids
sources.
Relationships of flow, concentration and
loading rate during events
Trends in the relationship of flow, concentration and loading rate
during individual events are illustrated with data from a few well-sampled
events. Patterns in flow, concentration and loading rates of suspended
solids, total- and soluble-P, chloride and lead, during the course of an
event were observed by plotting them against time (Figs. I-A-5 to I-A-14).
Events were selected from stations 683001, 413007, 413006 and 413005. The
loading rate was calculated by multiplying the flow and concentration values.
Additional events were selected to demonstrate the concentration patterns of
all the frequently analyzed parameters (Tables I-A-41 to I-A-46). Flow and
time of sampling are included in the tables along with the concentration
data. The relationships of flow, concentration and loading rates of suspend-
ed solids, total- and soluble-P and chloride during events were further
characterized by determining relationships using simple regression and
correlation analysis. To depict these relationships, data from two events
at station 413006 and one event at station 413005 were plotted and regression
equations and correlation coefficients determined (Figs, I-A-15 to I-A-23).
The levels of suspended solids, total-P, lead, and flow always increas-
ed significantly over baseflow levels during the course of an event (Figs.
I-A-5 to I-A-14). Concentration curves for suspended solids, total-P and
lead almost paralleled the hydrograph at all stations. In approximately
50% of the events evaluated, the concentration curves of suspended solids
and total-P were shifted to the left of the peak of the hydrograph. Thus
the peak concentrations were reached before the peak flow and decreased
rapidly on the descending part of the hydrograph. Soluble P levels usually
did not increase during events and the curves did not follow the shape of
the hydrograph. The same pattern was observed in the mean seasonal concen-
trations discussed earlier. The variability in concentration values for
these parameters reveals that a runoff event can only be characterized
fully by sampling across the entire hydrograph. Loading rates of the three
parameters followed the behavior of the hydrograph. It appears that flow has
a greater influence on the loading rates of soluble-P than on concentration.
The higher concentrations of total-P, suspended solids and lead during
individual events again dramatize the important impact of urban runoff on
river water quality. Similar results were observed for mean seasonal event
concentrations.
Strong linear correlation was always observed between loading rates
1-29
-------
and flow for all parameters evaluated (Figs. I-A-18 to I-A-20). The relation-
ships of suspended solids, total-P and chloride concentrations to flow (Figs.
I-A-15 to I-A-17) and loading rates (Figs. I-A-21 to l-A-23) were less
predictable. The concentrations of suspended solids and total-P were signifi-
cantly correlated with flow and loading rates for one event at station 413006
but not for the other event evaluated. The concentrations of soluble-P and
chloride were never correlated significantly with flow or loading rate. These
results suggest that flow is more important to the determination of loading
rate than the concentration of the parameter.
The degree of data points scatter determines the significance of the
correlation coefficients. It is also important to note the variability in the
values of the slopes and intercepts of the regression equation for the same
parameter. Regression equations are probably not transferable from one event
to another without averaging the slope and intercept values from a large
number of events.
Monitored Loading Data
Seasonal loading
Seasonal water and other parameter loadings were determined for the
mainstem river stations during runoff events and baseflow. Runoff event
loadings do not include baseflow loadings during events and thus provide
estimates of non-point source pollution from land use activities in the area
tributary to each station. Seasonal baseflow loadings were added to the
seasonal event loadings to estimate total seasonal loadings. The importance
of non-point source pollution in the Watershed was determined by comparing
total seasonal loadings with seasonal event loadings. Parameter loadings were
determined using a random sampling technique enhanced by a ratio estimator.
The method is described in the Materials and Procedures section. Water load-
ings were calculated by integration of flow values with time.
Seasonal event unit area loadings of parameters in water are presented in
Tables I-A-47 to I-A-51. Parameter loadings were determined for suspended
solids, total- and soluble-P and lead. The error estimator for each parameter
loading is presented as the 95% confidence interval. The mean flow-weighted
concentration for the season was calculated by dividing the seasonal event
parameter loading by seasonal event water loading.
Parameter and water unit area loadings (unit loading will be used here-
after) varied for each season at the same station. Loadings also varied
between years for the same station. Parameter and water unit loadings during
fall were always lower than those observed during spring and summer. The
trends between spring and summer unit loadings were less consistent. In 1976,
the spring parameter and water unit loadings were significantly higher for
most stations than summer loadings. However, summer unit loadings were higher
than spring loadings in 1977. Unit loadings of suspended solids during spring
and summer in 1975 were similar for most stations. Spring loadings were
higher than summer loadings for those stations with significantly different
suspended solids loadings in 1975. The number of groupings in each season for
1-30
-------
suspended solids unit loadings ranged from 3 to 6; total- and soluble-P unit
loading estimates fall into 2 or 3 groups. Variations of unit loading
estimates for total- and soluble-P between stations were less than those for
suspended solids. Although the nine mainstem river stations can be ranked
into groups, the stations found in each group can vary between seasons, years
and parameters. Ranked groupings of stations for annual event unit loadings
of 3 parameters are shown below. The Honey Creek station (413006) usually was

amongst the stations included in the highest group for water and parameter
unit loadings. The Honey Creek tributary area has the largest percentage of
urban land uses; its connected imperviousness (28%) is high relative to the
tributary areas of the other stations. The River Lane site (673001) was
usually amongst the stations with lowest water and parameter unit loadings.
The tributary area for the River Lane site contains the smallest percentage of
urban land uses with very low connected imperviousness (1%). The non-point
contribution unit area appears to be higher from the more urbanized tributary
areas.
The seasonal and annual event unit water and parameter loadings were
determined for the areas adjacent to stations at Pilgrim Road (683002), 124th
Street (683001), 70th Street (413005), and Falk Corporation (413004) stations
1-31
-------
(Table I-A-52). The adjacent area unit loadings were determined by subtract-
ing the upstream event loadings from the downstream event loadings and divid-
ing the difference by the area adjacent to the station. The adjacent area
unit loadings for the stations (413007, 413006 and 413008) without upstream
stations are presented in Tables I-A-47 to I-A-51. Based on the adjacent
areas, the Menomonee Watershed can be divided into eight separate areas with
independent loading values. Subtraction of areas of upstream stations for the
4 stations (683002, 683001, 413005 and 413004) listed in Table I-A-52
increases the percentage of urban land uses contributing to the stations.
This is especially true for stations 413005 and 413004 which include all the
more rural upper watershed in their tributary areas. The adjacent area unit
loadings for the four stations were usually higher than the tributary area
unit loadings. Increase in unit area loadings was variable; adjacent area
unit loadings of suspended solids for several seasons increased more than
twice over those of the tributary unit area loadings. By using the adjacent
area unit loadings the ranking of the stations within a season is changed. In
four of the nine seasons monitored, suspended solids unit loadings at 70th
Street were high enough that the station was included in the highest ranked
group. Caution must be used in the interpretation of the adjacent area data
for the above four stations since large variances in the estimates of loadings
produced several negative loading values. Also, an error estimate for the
adjacent area unit loadings could not be determined. However, the results
indicate that an increase in the percentage of urban land uses is accompanied
by an increase in unit loadings.
The annual water, suspended solids and total-P loadings were determined
for the three sewage treatment plants discharging into the Menomonee River and
were compared to the annual event loadings (Table I-A-53). The annual non-
point source pollution was significantly higher relative to the total (event
plus baseflow) annual loadings than the point sources in the Menomonee River
Watershed. The baseflow loading would account for the remainder of the total
annual loadings. The relative point source contribution of total-P was much
higher than the value for suspended solids. Other important point sources of
pollutants to the Menomonee River are the 23 combined sewer overflow (CSO)
outfalls between the Falk Corporation station (413004) and the confluence of
the Menomonee and Milwaukee Rivers. The Milwaukee Metropolitan Sewerage
Commission has estimated that approximately 2.0 x 10 kg of total-P and 1.6 x
10 kg of suspended solids are discharged annually from the 23 CSOs to the
river. Direct comparison of the CSO loadings with average annual loadings is
difficult because the CSO values include point and non-point contributions;
however, they are important sources of pollution since the annual CSO loadings
were of the same order of magnitude as the average annual event loadings.
Seasonal and annual total parameter and water loadings were determined by
combining baseflow and event loadings (Tables I-A-54 to I-A-57). That portion
of the total loading due to events was also calculated. Since the total
loadings are not expressed as unit loadings, the ranking of the stations
within a season is not possible because the magnitude of the loadings is
related to the size of the tributary area. Highest loadings were always
observed at the 70th Street site which drains most of the Watershed. As with
the seasonal event unit loadings, total loadings were highest during the
spring of 1976 and summer of 1977. The total water loading was always highest
during the spring of 1975, but trends for suspended solids total loadings
between spring and summer were variable. Since the fall total and unit
1-32
-------
loadings are always the lowest of any season, highest loadings occur either in
spring or summer. The percentage of total loadings due to events is always
highest for suspended solids; at most of the stations about 80% of the total
suspended solids loadings was contributed by events. Far more of the total
loadings of suspended solids and total-P was generated during events than was
the case for water and soluble-P loadings. The data are consistent because of
the relatively low suspended solids and total-P concentrations observed during
baseflow surveys. Soluble-P concentrations during events were similar to
baseflow values. Contributions of events to pollutant loadings differed
between stations. The percentage of total parameter and water loadings
contributed by events increased from the rural to the urbanized areas of the
Watershed. The low event contribution observed at the River Lane station can
be explained by the high perviousness and very low connected imperviousness of
its tributary area. The relatively large amount of pervious area of this
station reduces the amount of runoff. Approximately 50% or more of the annual
parameter and water loadings at many of the stations monitoring urbanized
areas is'due to events.
The calculation of annual and seasonal event loadings included flow and
concentration data from events of widely differing magnitudes. The events
with exceptionally large amounts of rainfall appear to contribute a
significant portion of the annual event loadings. Calculation of event data
from 70th Street revealed that 48 and 59% of the total-P and suspended solids
annual loadings, respectively, occurred during three rainfall events—namely,
March 1-9 cm, April 23 - 7.5 cm and May 5-5 cm—in 1976. Two rainfall
events—namely, June 6 - 5 cm and July 17 - 10 cm in 1977 accounted for 37 and
30% of the total-P and suspended solids annual event loadings, respectively.
Factors affecting loading
When analyzing the factors affecting loadings at the inainstem stations it
is useful to differentiate between the two components of loading. Initially
the runoff (water loading) and concentrations play dependent roles in the
calculation of loadings. Evaluation of the impact of the factors on the
loading components provides an understanding as to the manageability of non-
point source pollution.
The most important hydraulic factor affecting urban runoff is the portion
of impervious areas directly connected to the stream or drainage system. Most
types of urban development in the Menomonee River Watershed have impervious
areas directly connected to a subsurface storm sewer system which drains to a
stream. The street surfaces and parking lots are usually about 90% connected
and rooftops about 25% connected to a storm sewer. The results of connecting
impervious areas to storm sewers or rivers is to increase the amount and
intensity of runoff. This result was observed in the seasonal unit water
loading data. The highest unit water loadings were associated with the
station (413006) having the largest percentage of connected impervious area.
This relationship was shown further when unit loadings were calculated based
on areas adjacent to the station. Other hydraulic factors included slope,
rainfall intensity, soil permeability, land cover and depression storage.
These factors have greater influence on runoff quantity from pervious areas
than from impervious areas. All of the tributary areas for the mainstem sites
1-33
-------
contain large amounts of pervious area. Thus the observed seasonal unit water
loadings were affected by all the above hydraulic factors. Management of the
factors controlling urban runoff would be difficult or impossible. Reducing
the degree of connected impervious area would be most beneficial in developing
areas.
The concentration component is largely affected by the land use
activities. The potential amount of material available for transport is
determined by land use activities. Construction activities disturb vegetative
cover and expose soils to erosion. Heavy traffic and air pollution in indus-
trial, commercial and residential areas increase the accumulation of
pollutants on impervious areas. The observed increases in concentration of
suspended solids, total-P and lead during events revealed that a source of
these pollutants existed in the tributary areas of the mainstem stations.
Because of the multiple land uses in each tributary area, attempts to isolate
the important sources of these pollutants is difficult. It is assumed that
the largest source of suspended solids in an urban area is construction sites
while lead originates largely from vehicular emissions deposited in streets
and parking lot surfaces. The fact that chloride concentrations only increase
in spring indicates that road salting is the only important source of this
contaminant. Factors affecting delivery of pollutants are important in
controlling the concentrations of materials transported. Hydraulic factors
affect the transport of pollutants. Increasing the amount of runoff by any of
the hydraulic factors will increase the transport of many of the pollutants.
Large areas of connected imperviousness affect the transport of pollutants
from urban areas by increasing scouring energy and velocity of overland
flow. Thus, both the hydraulic factors and land activities contributing to
high concentrations of pollutants should be considered in the development of a
management strategy for urban areas. Both components of parameter loadings
affect the level of non-point source pollution, but runoff may exert a greater
influence than concentration.,
The relationship of runoff to parameter loadings is demonstrated in Figs.
I-A-24 to I-A-30. The parameter loading was almost always highly correlated
to the water loading. Loadings of suspended solids, total- and soluble-P for
seasonal and individual events usually increased with increasing runoff for
all four stations evaluated. As mentioned earlier the most important hydrau-
lic factors affecting urban non-point pollution is the degree of connected
imperviousness. Correlation analysis showed that the seasonal suspended
solids, total-P and water loadings were related significantly to the percent
connected imperviousness for the spring and summer of 1977 (Figs. I-A-31 to I—
A-34). This relationship was not observed consistently in 1975 and 1976. The
variability in the relationships in different years is probably due to the
effect of both the hydraulic factors related to the amount of runoff on the
pervious areas and the small range in connected impervious areas for seven of
the mainstem river stations. The importance of the degree of connected imper-
viousness is sometimes masked by the large amounts of rural pervious areas in
each of the tributary areas.
The results reveal the importance of a remedial policy based on controll-
ing hydraulic factors that are manageable. However, a policy to control the
transport of pollutants would be shortsighted if it did not also include the
control of sources of high pollutant concentrations. Implementation of
erosion control practices at construction sites is an obvious example.
1-34
-------
Controlling hydraulic factors will involve long term policies which involve
reduction of connected imperviousness in developing urban areas.
Rainfall-Runoff Relationship
Rainfall events and snowmelt generate runoff and pollutant washoff but
amounts of runoff and pollutant loadings are not always correlated signifi-
cantly with the amount of rainfall. This relationship of runoff and event
suspended solids with rainfall for seasonal and individual events is demon-
strated in Figs. I-A-35 to I-A-38. Data for the individual events are
presented in Table I-A-58. Of the four mainstem river stations (683001,
413007, 413006 and 413005) evaluated runoff was correlated significantly only
with rainfall at the Honey Creek (413006) station. The relatively high amount
of connected imperviousness at station 413006 probably explains the high
correlation. The seasonal event loadings of suspended solids were highly
correlated with rainfall for stations at 70th Street (413005) and River Lane
(673001) but not for stations at Honey Creek (413006) and Underwood Creek
(413007). In contrast, the individual event suspended solids loading was
highly correlated with rainfall for the three stations (683001, 413006 and
413005) evaluated. The general lack of significant correlation between runoff
and rainfall is attributed to other hydraulic and hydrologic factors affecting
runoff from pervious areas. Factors like evapotranspiration, soil permea-
bility and rainfall intensity will affect runoff differently throughout the
year and cause the observed variability in the relationship between runoff and
rainfall at stations with tributary areas having a large degree of pervious
surface. For example, evapotranspiration will reduce the amount of runoff
more in the summer than in the spring. The tributary areas with a large
percentage of connected imperviousness would be expected to show a more signi-
ficant relationship between runoff and rainfall, as was observed at station
413006.
The effect of hydraulic and hydrologic factors on runoff is further
demonstrated by observing the relationship between percentage runoff and
rainfall amount for each season (Table I-A-59). More rainfall occurred in the
summer of 1975 than in the spring, but the spring evinced a higher runoff
percentage. In 1977, summer had higher rainfall than spring but the runoff
percentages were similar for both seasons. Furthermore, spring 1976 had the
highest rainfall and percent runoff values. Again factors affecting runoff in
pervious areas including evapotranspiration, rainfall intensity, depression
storage, and soil permeability would account for the variability in the
relationship between percent runoff and rainfall. Even with lower rainfall
these factors could result in percent runoff values at least similar to those
observed in summer. Spring is characterized by more saturated soil conditions
because of such phenomenon as snowmelt, and lower evapotranspiration rate.
The presence of frost in the soil at the onset of spring will also increase
runoff in this season. Approximately 10 cm of rain fell on frozen ground in
1976 and about 3 cm in both 1975 and 1977. The stations with the lowest
connected imperviousness area usually had the lowest percentage runoff. The
trends in rainfall amounts during the spring and summer of 1976 and 1977 were
similar to the trends observed for the seasonal event parameters and water
loadings. The rainfall amounts and loadings were highest in the spring of
1976 and summer of 1977. As previously discussed, the water and pollutant
1-35
-------
loadings do not always have a significant correlation to rainfall when all the
seasons are included in the evaluation of each station.
First Flush Analysis
Previous urban monitoring programs have observed a first flush
phenomenon, or the passage of the largest percentage of the pollutants in the
early part of an event. As defined in this study, first flush occurs when the
percent of the total parameter load discharged exceeds by more than 20% the
corresponding percent of total water discharged. The comparisons are valid at
any point in the event before 50% of the water is discharged. A first flush
will occur if exceptionally high pollutant concentrations occur before peak
flows are reached.
The first flush analysis for two events at station 413005 and 413006 are
presented in Table I-A-60. A first flush was evident for suspended solids and
total-P during some events but none was observed for soluble-P. Thus a moder-
ate first flush probably occurs sometimes at the mainstem river stations. The
observed first flush probably has limited application to a remedial program.

*Adjacent area unit loading is determined by subtracting total loading(s) of upstream station(s) from total loading of a downstream
station within the same tributary area and dividing the difference by the area adjacent to that station (e.g., sum of total load-
ings at 683001, 413008, 413007 and 413006 subtracted from total loading at 413005).
**Unit loadings for stations without upstream stations are presented in Tables I-A-47 to I-A-50.
***Large variances in the estimate of loadings produced negative adjacent area unit loadings. For example, total loadings at 413005
were, in some cases, similar or less than the sum of total loading estimates at four stations above it.
i.d. Date insufficient for determination of loading.

PART II
QUALITY OF RUNOFF FROM PREDOMINANTLY
SINGLE LAND USES
by
G. V. SIMSIMAN
G. CHESTERS
and
J. GOODRICH-MAHONEY
Il-i
-------
ABSTRACT
The quality of runoff from ten predominantly single land use areas (50 to
2,040 ha) were monitored in 1976 and 1977 using automatic flow recording and
water sampling instruments. Seasonal flow and concentration data for 26
parameters monitored throughout the study are documented, although
discussion is focused on the key parameters—suspended solids, total P, lead
and cadmium—to demonstrate seasonal and site differences. Data for
bacterial counts and PCB concentrations determined sporadically are also
included. Evaluation made on the concentration data includes 1. comparison
with water quality criteria, 2. correlation analysis to show interrelation-
ships among parameters and 3. behavior of parameter concentrations and
loading rates during an event.
Seasonal unit loadings of 21 parameters estimated by a statistical
model enhanced by a ratio estimator are presented. Main hydraulic and
land activity factors affecting variations of loadings from location to
location are discussed. These factors affect either the amount of runoff
generated or the pollutant concentration. Remedial measures should be
oriented towards those land use areas (heavy industry, freeway and commer-
cial), which because of their high connected imperviousness, generate high
amounts of runoff (loads), and towards curtailing those land activities in
land use areas like heavy industrial, freeway, commercial and developing
medium density residential areas, which result in high pollutant concentra-
tions.
Other data evaluated are 1. rainfall-runoff relationships and 2. occur-
rence of first flush.

II-l. INTRODUCTION
The heterogeneity of land uses in the Menomonee River Watershed pre-
cludes the use of most of the river and tributary sampling stations as
predominant single land use study sites. Additional monitoring stations
were built at the outlets of homogeneous and/or predominant land use areas
in the Watershed to define more precisely the quantity and quality of
stormwater from these areas. These study sites are representative of the
major land uses in the Watershed, and data gathered at the monitoring
stations complemented data from the major river and tributary monitoring
stations. Data from the predominant land use stations were also used to
calibrate the LANDRUN overland flow model described in (1) •
II-l
-------
II-2. CONCLUSIONS
Considerable fluctuations of flow and parameter concentrations
occurred between seasons at a given station and between stations during a
season. Flow and parameter concentrations as examplified by the key param-
eters—suspended solids, total P, lead and cadmium—were high in stations
with high connected imperviousness (413616, 413615 and 413010) and low in
stations with negligible connected imperviousness (413625 and 683090).
There was a dramatic effect of land use type on lead levels; high concen-
trations observed at the freeway (413615) and heavy industrial (413616)
sites and low concentration at the low density residential (413625 and
683090) and agricultural (463001) sites.
Comparison of overall mean parameter concentrations with water qual-
ity criteria indicates that the runoff contaminants that are most likely
responsible for water quality impairment are lead for domestic water
supply; suspended solids and zinc for aquatic life; total P for eutrophi-
cation; and fecal coliform for swimming.
Linear correlation analysis of overall parameter concentrations demon-
strated significant associations of suspended solids with nutrients (except
soluble species) and several metals. This relationship was also observed
seasonally for individual stations. Soluble P tended to have a low or
inverse relationship with suspended solids. The significant correlations
of suspended solids with total P and metals suggest that a management
scheme which includes removal of suspended solids from stormwater also
reduces associated pollutants.
Bacterial counts increased during events at two medium density resi-
dential sites (413011 and 413010) but not at the agricultural site (413001).
PCBs were detected sporadically during some events, particularly at the
heavy industrial (413616) and freeway (413615) sites.
During events, concentrations of suspended solids, total P and lead
increased generally at the rising stage of the hydrograph as increased
flow produces simultaneous scouring of particulate materials. Loading
rates of the above parameters including soluble P were associated closely
with flow and occasionally with concentration. A wide variation in con-
centrations occurred over the hydrograph which emphasizes the importance
of obtaining several samples during runoff to obtain a better representa-
tion of the event.
Water and pollutant loadings varied considerably from season to
season at each station and from station to station for each season.
Seasonal and site differences were accounted mostly by variations in the
amount of runoff and, to some extent, by the variation of pollutant
concentrations.
II-2
-------
In order to devise a hazard-ranking system for homogeneous land use
areas, it is imperative to identify factors responsible for accelerated
pollutant loadings, namely, hydraulic factors which determine amounts of
runoff and land use/activities that affect pollutant concentrations. The
main hydraulic factor affecting runoff generation is the connected imper-
viousness of a specific area. Storm-sewered areas with high connected
imperviousness (413616, 413615 and 683089) do not only generate high amounts
of runoff but also typically export high pollutant loads. Stations with
natural drainage systems and low connected imperviousness (413615 and
683090) have relatively lower runoff and typically generate much lower
pollutant loads. Some land use/activity factors are long term which cause
either persistently high concentrations, such as high lead values from
heavy traffic (413615) and heavy industry (413616) areas or persistently
low concentrations such as the apparent increased trapping efficiency for
suspended solids and associated pollutants at stations 413625 and 683090.
Other factors affecting pollutant concentrations are either temporary or
seasonal, notably, construction and salting activities. Remedial measures
should be oriented not solely on land use type but rather towards curtailing
those short term land activities which result in high pollutant concentra-
tions, and towards those areas, which because of their hydraulic character-
istics like high connected imperviousness, generate persistently high
pollutant loadings.
Analysis of rainfall-runoff relationship indicates that the amount
of runoff was associated closely with rainfall only in areas with high
imperviousness. The percentage of runoff did not necessarily increase with
the size of rainfall event. The time elapsed since the previous rainfall
affected neither runoff nor pollutant loadings.
The occurrence of first flush is apparent particularly in areas
with high imperviousness.

II-3. MATERIALS AND PROCEDURES
Study Sites
The predominantly single land use sites were selected to represent
most of the major land uses in the Menomonee River Watershed, namely;
residential, commercial, industrial, agricultural and freeway. Table II-l
and Fig. II-l show the land use distribution and imperviousness in the
drainage areas for the sites and relative location of the monitoring
stations, respectively. For more detailed description of the sites refer
to (2).
Sampling Equipment
Each station consisted of a flow control structure, stage recorder,
stilling well, automatic water sampler and protective enclosure (Table II-2
and Fig. II-2). Power was provided by either a direct electric line or a
12-volt heavy duty battery.
Sampling stormwater in urban areas poses a problem in that the high
percentage of impervious surfaces results in flashy or rapid increase and
decrease in discharge. Generally, sampling proportional to flow is
unsatisfactory since a fixed water load must be used to actuate the sampler.
To partially eliminate this problem, activation of the Instrument Sepcialties
Company (ISCO) 1680 sampler and event marker of the Stevens Type A Model 71
stage recorder strip chart was accomplished using an electromechanical
system (Fig. II-3). Mounted on the 750 mm circumference float pulley of
the stage recorder were fifteen magnets spaced 5 cm apart. As the float
pulley rotated, with changing stage, the magnets came to near contact with
a mangetic reed switch. The closure of this switch, induced by the magnetic
field, activated the ISCO sampler. The system was set up such that at the
initial change in stage the ISCO commercial sampling. After this sequence,
the sampler oeprated after a set number of pulse counts (magnetic reed
switch closures) determined from field observations and the hydraulic
characteristics of the drainage area of the site.
During the interval of sampling the ISCO sampler's event signal was
used to activate a single pole double throw (SPOT) relay (Fig. II-3). This
SPOT relay controlled the event marker push solenoid to which a pen was
mounted. For the duration of sampling, an event mark was written on the
strip chart. After the sampling was completed the SPOT relay, push solenoid
and pen returned to a relaxed position.

Sample Collection, Handling and Preservation
During storm events, samples at sites 463001, 413010 and 413011 were
collected by PS69 samplers using the "time" mode, i.e. samples were taken at
a predetermined time interval (see Part I for description of sampling).
Samples from the other stations (413616, 413615, 413010, 413011, 683089,
413034, 463001, 413625 and 683090) were obtained either by "time" or "flow"
modes. During spring snowmelt, when the stage increased slowly during the
day, the ISCO samplers were actuated in the "time" mode by a microswitch on
the moving pen assembly of the water level recorder. During the remainder of
the sampling season, the samplers were actuated in the "flow" mode by a reed
switch mounted opposite the float wheel of the water level recorder as
described earlier. Magnets, mounted near the circumference of the float
wheel, closed the switch and actuated the samplers for a predetermined change
in water level.
Table II-3 shows the storm events sampled in 1976 and 1977 at the
predominantly single land use monitoring sites. Several samples were
obtained over the hydrograph during an event. The inclusive dates
corresponding to the seasons for the 2-year period were as follows:
Season 1976 1977
Spring Feb. 10 to May 31 Mar. 3 to May 31
Summer June 1 to Sept. 30 June 1 to Sept. 30
Fall Oct. 1 to Dec. 20 Oct. 1 to Dec. 20
Winter Dec. 21 to Mar. 2 Dec. 21 to Mar. 2
The spring season was reckoned as the first snowmelt that resulted in
runoff.
Samples were collected and/or composited at the sites as quickly
as possible after an event. Different sample volumes were required for
the various parameter groups analyzed (Table II-4). Samples for nutrients
and other parameters (1 L), bacteria (250 ml) and metals (250 ml) were
contained in plastic bottles while those for organic (2 to 3 L) parameters
were stored in glass bottles. Samples were either sent immediately to the
State Laboratory of Hygiene at the University of Wisconsin-Madison (a
distance of 113 km) or, if not warranted, brought to the Wisconsin
Department of Natural Resources (WDNR) Southeastern District Laboratory
in Milwaukee, for appropriate storage (Groups A and C samples were frozen;
Group D samples were refrigerated). All samples except those for Group D
were packed with ice in insulated containers and sent via a special U.S.
mail-parcel post to the State Laboratory of Hygiene for analysis. Samples
for Group D parameters were picked-up from the DNR Southeastern District
Laboratory.
Non-event or baseflow samples were collected by manual activation
of the water samplers. Only sites 463001 and 413011 were sampled during
baseflow because the other stations either had intermittent or no flow
during dry periods. The handling and volumes of samples for the various
groups of parameters were the same as those for the event samples.

Nutrient analysis and bacterial counts were performed immediately
after receiving the samples in the laboratory. Samples for metal analyses
were acidified and refrigerated after removing aliquots for the analysis
of dissolved reactive silica. Samples for organics were refrigerated
until extraction could be performed.
Laboratory Analysis
Groups A and B parameters
Analysis of parameters under Groups A and B were performed at the
State Laboratory of Hygiene. Nutrient forms under Group A parameters
were determined following the procedures recommended by the U.S.
Environmental Protection Agency (3). Group B and the rest of Group A
parameters were determined according to the methods described in (4).
Groups C and D parameters^
These parameters were analyzed in the Water Chemistry Laboratory of
the University of Wisconsin-Madison.
Samples for metal analysis were acidified in the shipping bottles
(3 ml HN03/50 ml sample) after aliquots (25 ml) were removed and filtered
through 0.4 ym Nucleopore membrane for dissolved reactive silica determina-
tion. Acidified samples were digested according to the technique recommend-
ed by the U.S. Environmental Protection Agency (3) for total metals in
waters. Depending upon the level of metals, concentrations were determined
by flame or flameless atomic absorption spectrophotometry (AAS) using a
Perking-Elmer Model 603 Atomic Absorption spectrophotometer equipped with
an HGA 2100 graphite furnace accessory. Iron, Mn, Zn and Cu were analyzed
by flame AAS while Cr, Cd, Ni and Ac—because of their low concentration—
were detected by flameless AAS utilizing a deuterium arc background
correction. The detection of Pb required an electrodeless discharge source
to lessen noise and permit a greater expansion scale. Iron and Al were
measured to 100 yg/L; Zn, Cu, Mn and Pb to 10 g/L; and Cr, Cd, Ni and As
to 1.0 yg/L. Selenium was not determined regularly because of its
extremely low concentrations in runoff water, thus adequate deuterium
background correction was not attained.
Dissolved reactive silica was determined by formation of the silico-
molybdate complex and spectrophotometric measurement of the absorbance at
810 m (5).
Extraction of organochlorine insecticides and PCBs from runoff samples
was accomplished using the U.S. Environmental Protection Agency method (6).
Further cleanup of extracts was performed utilizing the alumina column
chromatography technique to obtain samples suitable for PCB analysis.

Calculation of Loadings
Water loadings were estimated by integration of flows over the hydro-
graphs of all events recorded. Parameter loadings were calculated using
a stratified random sampling statistical model enhanced by a ratio
estimator described in (7).
Key Parameters
Two major types of pollution arising from nonpoint sources have been
identified in the Great Lakes Basin, namely, nutrients and sediment which
accelerate eutrophication of lakes and toxic materials which constitute a
public health hazard and a hazard to the biological communities of the
lakes. The basic guidelines used in selecting key parameters for these
types of pollution are 1. the pollutant must be present in significant
amounts in the watershed and 2. it must be amenable to remedial control
measures. The key parameters selected include suspended sediment; total
phosphorus; toxic metals, primarily Pb, Cd, Cu, and Zn; and toxic organic
materials, principally pesticides, PCB, and phenols. The parameters deemed
to be of greatest importance in the Menomonee River Watershed are:
Suspended sediment, total phosphorus, lead and cadmium. Discussion of
results will focus primarily on these parameters.

II-4. RESULTS AND DISCUSSION
Flow and Concentration
Seasonal flow and concentration
Detailed flow and concentration data for storm events measured in 1976
and 1977 as well as concentration data of non-event samples obtained in the
same period were placed in STORET. Computer tapes and printouts of the data
are available from the Water Resources Center, University of Wisconsin-
Madison.
Event seasonal flow and concentrations of 24 parameters in ten predomi-
nantly single land use monitoring sites during 1976 and 1977 are presented
in Appendix II-A, Tables II-A-1 to II-A-26. These tables contain arithmetic
means and ranges of flow and parameter concentrations, standard deviations
and number of samples for each station.
Although flow and concentration measurements were made for 1976 and
1977 only the latter data were used for comparison because 1. drought
conditions occurred in 1976 and 2. stations were sampled uniformly in 1977.
The highest flow of runoff water was observed during summer at most stations
and only a slight flow variation occurred between spring and fall. Generally,
the highest concentrations of suspended solids, total P, lead and cadmium
occurred in spring. It is interesting to note that the stations with the
highest concentrations of suspended solids also had the highest concentrations
of total P, lead and cadmium. Such high concentrations of suspended solids
and associated parameters during spring could be due to low flow and/or to
more particulate materials available for transport. However, it appears that
more particulate materials are transported in spring as borne out by the
considerably lower concentrations of suspended solids and associated para-
meters in the fall compared with spring despite the similarity of flows
during the two seasons. Soluble P (dissolved reactive P) concentrations did
not vary between spring and summer. Chloride concentrations in spring were
high largely as an aftermath of road salting during previous winter months.
Flow and parameter concentrations differed widely between stations
during a season. In general, runoff flows were high for stations that have
high connected imperviousness, e.g., stations 413616, 413615 and 413010.
Lower flows were observed for stations with low connected imperviousness as
shown at sites 683090, 413625 and 413614. High levels of suspended solids
and total P were detected at stations 463001, 413615, 413010, 413616, 683089
and 413034. The relatively high concentrations of suspended solids and
total P at station 463001 indicate that soil erosion is active and fertilizer
11-15
-------
being applied in the adjacent agricultural drainage area. High concentrations
of lead were found at stations 413615, 413616, 413034, 683089 and 413010.
Highest values occurred at sites 413615 and 413616; the drainage areas of both
stations are freeway and heavy industrial complex, respetively. Automobile
exhaust may contribute largely to the high amounts of lead in heavily
traveled areas. Low lead concentrations were shown in areas of lower traffic
density as exemplified by site 463001 (largely agricultural land use) and
site 683090 (a low density residential area).
Seasonal non-event or baseflow parameter concentrations were determined
for two stations—463001 and 413011 (Table II-A-27 and _I-A-28). The other
eight stations either had intermittent flow or remained dry during non-event
periods. Generally, non-event concentrations of several parameters were
lower than event concentrations. This was exemplified by suspended solids,
total P and to some degree by soluble P. Lead concentrations tended to be
lower during non-events than during events although comparable data were
obtained only in the spring of 1976. The higher parameter concentrations
observed during events suggest that more materials are being carried by the
runoff water although dilution is occurring concomitantly as a result of
greater flow.
Bacteriological and organic pollutants
Bacterial counts were determined in non-event and event samples at three
stations (Table II-A-29). Although determinations were performed on only a
few samples, there was a tendency for coliform and fecal streptococcus counts
to be higher during events in the two medium density residential sites (413011
and 413010); this observation was not repeated at the agricultural site
(463001).
Organochlorine insecticides and PCBs were scanned for a number of event
samples. Levels of organochlorine insecticides were below detection limit.
PCBs were detected sporadically during some events, particularly in the
heavy industrial (413616) and freeway (413615) sites (Table II-A-30).
Comparison of stormwater r.unoff quality
with water quality criteria
Overall event mean concentrations of selected parameters during 1976 and
1977 at ten predominantly single land use sites were compared with water
quality criteria for domestic water supply and aquatic life (Table II-A-31).
The water quality values are recommended maximum limits designed to protect
the beneficial uses of receiving water with a reasonable degree of safety.
If a monitored concentration exceeds the criteria, it does not mean that a
problem exists but rather may indicate important sources of pollutants.
The following list summarizes those parameters that exceeded the
recommended beneficial use criteria:

Lead appears to be the main contaminant affecting the impairment of
domestic water supply. Mean values in all sites exceeded the limit. Except
for the agricultural (463001) and low density residential (683090) areas almost
all observed concentrations were higher than the recommended limit. Some
stations had runoff contaminated with other elements, i.d., cadmium and
chromium in the industrial site (413616) and chloride in the freeway area
(413615). Since metals were analyzed as total (particulate and soluble),
caution should be taken in comparing their concentrations with the criteria.
Bacterial counts in runoff tended to increase during storm events. In
three stations (413010, 413011 and 463001) where bacterial analysis was
performed, the swimming water criterion for fecal coliform was exceeded only at
site 413010, an established medium density residential area.
Stormwater runoff contains several contaminants that may affect its
beneficial use for aquatic life. Among the contaminants are suspended solids,
total P and such metals as zinc, copper and cadmium. Runoff mean concentra-
tions of total P and zinc at all stations exceeded the criteria. The limit for
suspended solids was exceeded at all sites except the low density residential
area (683090); copper at the established medium density residential site
(413010), the light industry site (413034), the freeway (413615) and the heavy
industrial site (413616); cadmium criteria were exceeded only at the heavy
industrial site.
The runoff contaminants arising from various land uses that are most
likely responsible for water quality impairment are lead for domestic water
supply; suspended solids and zinc for aquatic life; total P for eutrophication;
and fecal coliform for swimming.
Parameter concentration relationships
Correlation analyses between parameter concentrations were performed for
all data in 1976 and 1977 and by season at eight stations; correlation
11-17
-------
matrices are presented in Tables II-A-32 and II-A-33.
Multicolinearity did exist among many of the water quality parameters
(Table II-A-32). For example, high simple correlation coefficient values
(<_ 0.50) were demonstrated for 1. suspended solids with volatile suspended
solids, total P, total organic N, total organic C, copper, lead, zinc,
arsenic, nickel, iron, aluminum and manganese; 2. total P with the
parameters listed above and 3. among metals with the exceptions of cadmium
and chromium and occasionally with selenium. These relationships indicate
the close association of several of the paremters, particularly nutrients
(except soluble species) and metals, with suspended solids and the strong
interrelationships among lead, copper, zinc, arsenic, nickel, iron and
manganese. Apparently, the lower correlation observed for chromium and
cadmium with suspended solids is due to their weaker binding by solids as
compared to the other metals.
A significant correlation between suspended solids and total P was
observed almost consistently for each season at all stations (Table II-A-
33) . This trend was also found between suspended solids and lead and
between total P and lead except at sites 463001 and 683090. The breakdown
in the colinearity among these parameters in the two sites could be
explained largely by the low amounts of lead arising from the agricultural
(463001) and low density residential (683090) drainage areas. Soluble P
tended to have a low or inverse relationship with suspended solids. It is
likely that either the concentration of soluble P does not change or it
decreases with the increase in suspended particles in the runoff water.
The strong positive correlations of suspended solids with total P and
several of the metals particularly lead suggest that a management scheme
which includes removal of suspended solids from stormwater runoff also
reduces associated pollutants.
Relationships among flow, concentrations
and loading rates during events
Well-sampled events were selected from five stations—413615, 413011,
683090, 413625 and 463001—to illustrate typical variations of concentra-
tions and loading rates (instantaneous load) of suspended solids, total P,
lead and soluble P during an event (Figs. II-A-1 to II-A-7). The loading
rate was calculated by multiplying flow with the concentration at the time
a sample was collected. The percent load represents cumulative load; the
number on the last point being the total load at the end of sampling.
In order to gain further insight into the relationship of flow, concentra-
tions and input rates, regression and correlation analyses were performed
and examples of plots are shown in Figs. II-A-8 to II-A-13.
The data reveal that:
1. In general, the concentrations of suspended solids, total P and
lead increased during the rising stage of the hydrograph (Figs. II-A-1 to
11-18
-------
II-A-7). Highest concentrations occurred early in the storm usually near
the vicinity of peak flows. The relationship between the concentration of
soluble P and flow was not as distinct as the above parameters. Highest
concentrations of this soluble component were attained either early in the
storm or lagged after peak flows.
Although increased flow promotes dilution, it produces simultaneous
scouring of soil particles or particulate matter initially present on the
land surface, hence the increasing concentrations of suspended sediments
and associated pollutants during the rising stage of the hydrograph. The
decrease of concentrations during the falling stage indicates the exhaustion
of source materials.
Concentrations of parameters were found to be ocassionally correlated
with flow during events. These kinds of relationships are depicted in
Figs. II-A-8 and II-A-9.
2. Loading rates of suspended solids, total P, lead and soluble P were
associated closely with flow and concentration (Figs. II-A-1 to II-A-7).
High correlations existed between loading rate and flow but not consistently
between loading rate and concentration (Figs. II-A-10 to II-A-13).
It is noted that for several events examined loading rates tend to have
a consistently stronger correlation with flow than with concentration.
This implies that flow exerts greater influence on loading than concentra-
tion.
3. A wide variation in concentrations occurred over the hydrograph.
This emphasizes the importance of obtaining several samples during runoff
to obtain a better representation of the event.
4. Generally, more than half of the total load of the parameters
selected was transported immediately following major flows during events
(Figs. II-A-1 to II-A-7).
Event concentrations and loading rates of parameters other than those
mentioned above are presented in Tables II-A-34 to II-A-41 for selected
stations.
Monitored Loading Data
Seasonal loadings
Pollutant loadings were calculated using a stratified random sampling
statistical model enhanced by a ratio estimator while water loadings were
obtained by integration of flow for all events. Seasonal event unit
loadings of water and 21 pollutants deteremined at the ten predominantly
single land use sites are presented in Tables II-A-42 to II-A-63.
Included in the tables are 95% confidence interval values estimated for
11-19
-------
the loads and flow-weighted concentrations of pollutants. A pollutant load
divided by the corresponding water load gives the flow weighted concentration
for that pollutant.
Water and pollutant loadings varied considerably from season to season
at each station and from station to station for each season. During 1976
and 1977 highest loads occurred in different seasons. In 1976, the highest
pollutant loadings (suspended solids, total P and soluble P) was observed
in spring as exemplified by station 413010, 413011 and 463001—the only
stations sampled completely during the year. Conversely, in 1977, major
portions of the loads of suspended solids, nutrients and several of the
metals for most of the stations were generated in summer. It is evident
that the seasonal variation of pollutant loadings is influenced largely by
differences in the amounts of runoff. Most of the annual runoff (> 50%)
occurred during spring and summer in 1976 and 1977, respectively. Conco-
mittantly, the main bulk of the annual loads were attained during these
seasons.
Examination of pollutant loadings reveal that differences between
station within a season are due to the variation in the amount of runoff
and/or pollutant concentration. High pollutant loadings observed at
stations 413616, 413615, 683089, 413011 and 413010 were related to high
water loads and usually to high pollutant concentrations. For example,
this effect was exhibited for suspended solids and associated pollutants
such as total P and lead. Stations with low pollutant loads (413625 and
683090) had also low water loads and generally low pollutant concentrations.
The two components may exert varying degrees of influence but the data
indicate that the runoff yield has a greater effect on the magnitude of
pollutant loads from station to station.
Factors affecting loadings
In the analysis of pollutant loadings from predominantly homogeneous
areas, consideration must be given to their respective components. To the
degree that concentrations are similar, variations in pollutant loadings
are attributable to differences in the amounts of water load or runoff.
Likewise, to the degree that the amounts of runoff are similar, variations
in pollutant loadings are due to differences in concentration. Elaboration
of the factors affecting these components, hence pollutant loadings, is
extremely important so that those feasible to control through management
practices can be identified.
This dualistic analysis of stormwater pollution yields a two-sided
relative hazard-ranking systems. One aspect involves the hydraulic factors
which determine the relative amounts of runoff. In urban areas, these
primarily involve the nature of the drainage system and the degree of
imperviousness. The connectedness of impervious surfaces to drainage
systems determines the rapidity by which water is transported from the
drainage areas to receiving streams. Of lesser importance in determining
runoff in urban as compared to rural watersheds are soil permeability,
slope, ground cover, depression storage, etc. Storm-sewered areas with
relatively high connected imperviousness (413616, 413615 and 683089) do not
II-20
-------
only generate high amounts of runoff but also typically export high
pollutant loads. Additionally, there is not a strong dilutional effect
caused by the larger amounts of water. Rather, those stations with high
unit amounts of runoff often have high concentrations of pollutants. This
is likely caused by the easy washoff and efficient transport of pollutants
in curb and gutter storm sewer systems from impervious surfaces, and the
more intensive scour and transport capacities of larger volumes of water.
Stations with natural drainage systems and low connected imperviousness
(413625 and 683090) have relatively lower runoff and typically generate much
lower pollutant loads.
The other aspect of the relative hazard-ranking system pertains to
those land activities, land uses and land covers that affect the concen-
trations of pollutants. Some of these are long term factors which result
in persistently high concentrations, such as lead values from heavy traffic
or heavy industry at stations 413615 and 413616, respectively. Inversely,
some factors cause persistently low concentrations such as the apparent
increased trapping efficiency for suspended solids and associated
pollutants at stations 413625 and 683090 (statistical analysis shown earlier
revealed a significant correlation of suspended solids with total P, lead
and concentrations of other metals indicating that the latter
pollutants are strongly correlated with the solids fractions). Other
factors affecting pollutant concentration are of short term duration, i.e.,
either temporary or seasonal activities. Most visibly are the effects of
winter salting activities or chloride values at station 413615 during
spring and on suspended solids concentrations at station 683089 in the
spring of 1977. Some of the short term activities may mask longer term
differences, as at station 413011 where the impacts of ongoing construction
throughout the study period are impossible to separate from non-construction
related loads.
Water is the prime mover of pollutants and the more runoff generated
over the land surface the greater the pollutant loads. This relationship
is clearly demonstrated in Figs. II-A-14 to II-A-17). Loads of pollutants
such as suspended solids, total P, lead and soluble P increased significantly
with increased amounts of runoff regardless of the type of land use monitor-
ed. The single most important hydraulic factor affecting the generation of
runoff, and correspondingly pollutant loads, during storm events is the
connectedness of impervious areas to the drainage systems or receiving
waters. As shown for the 1977 data (Figs. II-A-18 to II-A-22), water
and pollutant loadings were related to the connected imperviousness;
significant correlation being observed more consistently for the summer and
annual loads.
It is apparent that no blanket remedial policy based solely on type of
land use is advisable. Rather, remedial measures should be oriented
towards curtailing those short term activities or phenomena which result in
high pollutant concentrations, and towards those areas, which because of
their hydraulic and/or other indigenous characteristics, generate long term
heavy pollutant loads. Undoubtedly, minimization of connected impervious-
ness in any future development or urbanization schemes could effectively
and inexpensively prevent high pollutant loads.
11-21
-------
Rainfall-Runoff Relationships
The amount, frequency and intensity of rainfall affects the amount of
runoff and resultant pollutant loads. These factors exert varying degrees
of influence and they may either enhance or depress runoff. Only the
effects of rainfall size and frequency are discussed. On-site rainfall
and corresponding runoff data obtained mostly in the summer of 1977 are
shown in Table II-A-64. Local variation in rainfall distribution was
observed at the sampling sites. For the same event, larger runoff usually
occurred in the relatively impervious areas (413615, 683089, 413011 and
413010) than in the pervious areas (413625, 683090 and 463001). Correla-
tion analysis of the data demonstrated clearly that a significant direct
relationship existed between the amount of runoff and rainfall for the
relatively impervious watersheds (Fig. II-A-23). This relationship was not
substantiated in more pervious watersheds, probably because larger rain-
falls are needed to exceed the saturation/infiltration capacity of the
soil before runoff occurs. Further analysis of the data showed the
absence of significant correlation between percent runoff and rainfall at
any of the sites (Fig. II-A-24). This suggests that the percentage of
runoff frequently does not increase with the size of an event.
Seasonal rainfall distribution at the various monitoring stations was
obtained by averaging information from all USGS rain gauges closest to the
sites (Table II-A-65). Most of the rainfall (> 60%) occurred during
spring in 1976 and during summer in 1977. A major portion of the annual
runoff was also generated during these seasons. It is interesting to note
that as shown earlier for individual events 1. the lowest seasonal runoff
generally occurred at the relatively pervious watersheds and 2. the amount
of runoff did not increase correspondingly with higher seasonal rainfall
in such areas.
The rainfall frequency or time elapsed since the last rainfall affects
the amount of runoff and accompanying pollution in two ways. In rural or
relatively pervious areas the amount of runoff should depend to a certain
extent upon the antecedent soil moisture conditions prior to an event.
When soil moisture content is high—which may occur when the intervals
between events is small—the infiltration capacity is exceeded rapidly
resulting in greater runoff and pollutant loads. Pollutant loadings in
relatively impervious areas may increase with prolonged intervals between
events due to accumulation of dust and dirt. Analysis of integrated water
and parameter loading data for well-sampled storm events (Table II-A-66),
however, showed no significant correlation existed between loadings and
days elapsed since the last rainfall at any of the monitoring sites
(Table II-A-67). Such low correlations (r= -0.422 to 0.464) indicate the
futility of predicting loadings based upon rainfall frequency because
different storm events vary in size and intensity. Furthermore, data from
this study cast serious doubt upon the validity of the assumption that
pollution from urban runoff increases with time elapsed since the previous
rainfall (10).
11-22
-------
First Flush Analysis
A frequently noted observation cited in the literature is the first
flush phenomenon, or the occurrence of highly concentrated pollutants in the
early stages of runoff. It has been commonly noted for areas of combined
sewers that the first overflows carry with them high concentrations of
scoured or flushed deposits. As defined in this study, first flush occurs
when the percent of the total parameter loads discharged at any point in
an event exceeds significantly the corresponding percent of total water
loads discharged. First flush is expected to be more prevalent during
larger storm events.
Cumulative water and parameter loads obtained by integration, for
closely monitored events are given in Table II-A-68 in urban areas with high
(683089), low (413614) and extremely low or negligible (413625 and 683090)
connected imperviousness. The amounts of rainfall during the events were
considered moderate to high (1.0 to 4.0 cm). Analysis of data indicates
that first flush occurred at all sites, particularly for suspended solids
and associated parameters such as total P and lead. Only occasional first
flush was observed for the dissolved species exemplified by soluble P.
The occurrence of first flush was more frequent at site 683089 which may
be explained largely by the higher connected imperviousness of its drainage
area which allowed easier transport of materials to the storm sewer system.
The concentration surge during the early stages of some events, as dis-
cussed previously, is dependent on the amount of materials available for
transport. Usually more materials are available for transport during the
initial stages of an event. However, trapping of materials during the
course of transport such as along natural drainage systems of pervious
areas tend to minimize first flush.
The implications of these findings are twofold, and are applicable to
areas with separate storm sewers or natural drainage ways. First, storage
and treatment of the initial portions of runoff may remove significant
amounts of pollutants depending upon the drainage areas under considera-
tion. Second, as the amount of pollutants are closely associated with
the amount of runoff, efforts to reduce the latter will result in reduction
of pollutant loadings.

ABSTRACT
The impact of agricultural and urban pollution from non-point sources
on benthic macroinvertebrate communities in the Menomonee River is evaluated
utilizing biological monitoring data collected by the Wisconsin Department
of Natural Resources (1951 to 1968) and University of Wisconsin Water
Resources Center (1975 to 1976).
Non-point pollution from agricultural areas in the headwaters of the
Menomonee River and point source pollution from industrial and commercial
areas mask any effects caused by pollutant-loadings attributable to urban
non-point sources. The diversity (genera level) and biotic indices can
locate areas of disturbance but cannot differentiate specific impacts of
major land use categories on macroinvertebrate communities. Due to the
relative intensity of the calculated indices, similar values are obtained
for the moderately polluted agricultural and urban areas even though the
macroinvertebrate genera may be different.

III-l. INTRODUCTION
The benthic macroinvertebrate community of the Menomonee River and its
tributaries was sampled by the Wisconsin Department of Natural Resources
(WDNR) from 1951 to 1968 (1 to 4). In 1975, the University of Wisconsin
Water Resources Center assumed responsibility for the biological monitoring
as part of the IJC-Menomonee River Pilot Watershed Study. This report
summarizes the earlier WDNR findings and examines the effect of agricultural
and urban pollution fromnon-point sources on aquatic macroinvertebrate
populations.
o
The Menomonee River Watershed is a surface water drainage unit, 352 km
in areal extent, located in the southeastern corner of Wisconsin (Fig. III-l).
The Menomonee River has its source in a woodland-wetland area located in the
northeastern corner of the Watershed in the Village of Germantown. The river
flows in a southeasterly direction for approximately 47 km and discharges to
the Milwaukee River at the City of Milwaukee. Approximately 26 km downstream
from the headwaters, the Menomonee River is joined by the Little Menomonee
River. The Little Menomonee River flows in a southerly direction for 16 km
before its confluence with the Menomonee River. Other principal tributaries
in the Watershed are Noyes, Underwood and Honey Creeks.
The average flow (1975 and 1976) upstream at Germantown was 0.43 m /sec,
the headwaters of the Little Menomonee at Donges Bay (STORET Station No.
463001) averaged 0.18 m3/sec and past the confluence, at 70th Street (413005),
the flow averaged 2.82 m3/sec (Table III-l).
Urbanization generally increases from the north to the south of the
Watershed. Existing urban land uses range from an intensely-developed
commercial/industrial complex in the lower quarter of the Watershed (City of
Milwaukee) to low-medium density residential areas in the center half while
the upper quarter is in the process of conversion from rural to urban. Noyes
Creek (413011), is an example of a rapidly urbanizing area.
The biological stations were arranged according to increasing urbaniza-
tion based upon 1975 land use data (5; Table III-l and Fig. III-2). Each
land use analysis included the total drainage basin of the station assuming
all land above a station will affect the water quality of the site. There-
fore, at 413005 the land use computation included the upper rural portion of
the Watershed although the biological community was predominantly affected
by the immediate surroundings (72% urban).
A rather large portion of the stream system has been altered for flood
purposes (Fig. III-l). In 1974, 67% of the perennial and intermittent
streams in the Watershed had undergone channel modification (6). Most of the
modification has been minor channelization consisting of localized clearing

and widening with scattered straightening. Only limited areas underwent
major channelization where extensive concrete or masonry was added to the
deepened, widened or straightened river. A conduit completely eliminated
the natural channel of a 3.7 km reach of Honey Creek (6).
Creosote pollution has been a problem in the Little Menomonee River
since the 1920's. Patchy deposits of the toxic hydrocarbon mixture are
found in the sediments from below the Moss American Railroad Tie Treating
Company to the confluence with the mainstern (7).
The stream bed substrate varies depending on the season and flow, but
generally it is sand and gravel (Table III-l). A layer of creosote-free silt,
sand, and detritus was found overlying the contaminated sediments of the
Little Menomonee (7).

III-2. CONCLUSIONS
Since macroinvertebrates were only identified to the genera level and
chironomids, oligochaetes and gastropods were treated as three groups the
sensitivity of the indices was impaired. However, even if taxonomic identifi-
cation had been performed to species level, relative ratings of the stations
would likely not be changed.
Environmental factors that influence community structure cannot be
disregarded. The physical effect of high currents on the benthic organisms
cannot be separated from the pollutional load. One cannot say if a material
will be harmful by its concentration alone. The effect of toxic substances
on the biota in the aquatic ecosystem depends not only on the concentration
of the toxicants but also on exposure time, environmental characteristics of
the receiving system, age and condition of the organisms and presence of
other toxicants (8).
The pollution from non-point sources from agricultural areas in the
headwaters of the Menomonee River and the point source pollution from
industrial and commercial areas of the Watershed are so large that they mask
any effects caused by the loadings attributable to urban non--point sources.
The diversity and biotic indices can locate areas of disturbance but cannot
differentiate specific impacts of major land use categories on macroinverte-
brate communities. Due to the relative insensitivity of the calculation of
indices, values obtained in moderately polluted agricultural areas are similar
to those values for areas with moderate urban pollution even though the macro-
invertebrate genera may be different.

Ill-3. MACROINVERTEBRATES AND WATER QUALITY
Stream macroinvertebrates spend all or part of their life associated
with the water and substrate. Their distribution is naturally regulated
by speed of the current, temperature, seasonal changes, substrate character-
istics, dissolved substances, food and competition and can be altered
indirectly by man's activities on land or directly by channelization and
dredging (9). Replacement of native plants by agricultural crops alters
the amount of sediment and nutrients entering the system. In the urban
environment, impervious surfaces cause other non-point pollution problems.
Macroinvertebrates are sensitive to water quality and because of their
relative immobility have been used as indicators (10). Species vary depend-
ing on the types and concentrations of pollutants they tolerate. Some
organisms are unable to exist when a slight change in the aquatic environment
occurs. If the intolerant forms are reduced or eliminated an increase in
the more tolerant organisms often occurs due to reduced predation and compe-
tition. In harsh environments only very tolerant organisms will survive.
A clean water community usually is balanced, meaning it is composed of many
species with a few individuals in each; this balance is changed by pollution.
Macroinvertebrate Sampling in the Menomonee
River Watershed from 1951 to 1975
A sampling program, in July 1951, indicated that a polluted condition
existed below the Rockfield Cannery near the headwaters of the Menomonee
River. The population of sludge worms and leeches likely was caused by the
company's discharge of waste material into the river. One mile below the
sewage treatment plant serving the Village of Germantown, the macroinverte-
brate community was typical of a highly polluted river system (1).
During sampling programs in May and July of 1953, the Menomonee River
from 124th Street to Capital Drive was found to support a clean water benthic
community. Near North Avenue—located below three combined sewer overflow
devices—it was evident that the biological community had been affected by
pollution. The biological communities in the Little Menomonee River at
County Line Road and at Highway 100 (Fig. III-l) suffered from high levels of
suspended solids arising from current topsoil removal. At County Line Road
the macroinvertebrate population was small and at Highway 100 only pollutant-
tolerant sludge worms lived in the oil- and tar-contaminated bottom muds. The
sample from Honey Creek at 84th Street and Honey Creek Parkway indicated
polluted conditions. An appropriate upstream station could not be found due
to dredging, concrete or hard clay bottom (2).
III-7
-------
In March and April of 1968 samples at 124th Street on the Menomonee
River indicated a balanced macroinvertebrate community; downstream the
community structure was unbalanced. Above the Moss American Company, on the
Little Menomonee River, the benthic community was balanced but polluted
conditions were found below the industrial site to the confluence with the
main stem.
In October 1966, a sampling program indicated a balanced community in
the upper Menomonee River. Below the Gehl Guernsey Farms, Inc. milk
condensing plant waste outfall and the Germantown sewage treatment plant
outfall, an unbalanced community existed. Above the Menomonee Falls sewage
treatment plant—at Pilgrim Road—clean water conditions supported a well-
balanced benthic community. Below the point source there was a marked
increase in sludge worms, snails and bloodworms indicating partially polluted
conditions. Downstream—at Mill Road—a clean water benthic community
indicated a recovery zone (3).
In October 1971 a qualitative study of the Little Menomonee River was
conducted and revealed varying degrees of pollution from below the Moss
American Company to the confluence with the Menomonee River (4).
In October 1975 a qualitative Surber benthic survey from the Menomonee
River indicated a relatively balanced benthic community from Friestadt Road
to Pilgrim Road, while samples from Currie Park and further downstream were
extremely unbalanced. Quantitative sampling was performed at Silver Spring
Road, Jacobus Park and Mill Road (Little Menomonee River). At all three
sites oligochaetes comprised > 50% of the population. At Silver Spring
Road the remainder of the community was composed of Chewnatopsyche and
Chironomids. Ascellus dominated the sample at Mill Road indicating an area
high in organic debris (11). Jacobus Park exhibited a reduced population
of Chironomids and Gastropods (Tables III-A-1 and III-A-2 in the Appendix).
In general, the early studies describe a partially polluted stream with
occasional areas of recovery (12).
Recent Macroinvertebrate Sampling in the
Menomonee River Watershed
The macroinvertebrate community was used to examine the impact of land
use on the biological community of the Menomonee River from May to August of
1976 (13). Five sites were selected for biological monitoring of which four
coincided with continuous monitoring stations nos. 413005, 683001, 413008
and 673001 and an additional upstream site No. 683002 (Fig. III-l). To
allow uniformity between sites each station was equipped with a floating
structure on which six modified Hester-Dendy artifical substrate samplers
were suspended.
These samples were supplemented by Surber samples—samples containing
organisms collected directly from the substrate—because of vandalism and
Chi-rononridae colonization of the Hester-Dendy samplers. One hundred organisms
were subsampled to represent the sample population (TablesIII-B-1 and
III-8
-------
III-B-2). A biotic index (14) was used to assess the water quality at each
station due to the subjective nature of classifying organisms into tolerance
categories. Organisms were assigned index values based on an assessment of
the organisms ability to withstand varying degrees of pollution. Organisms
found only in clean water received low values while organisms found in
polluted waters were assigned high values. An average quality value or
biotic index (Bl) was calculated for the sampled site by multiplying the
number of organisms in each species or genera "a" by its index value and
continuing for all genera in the sample. If careful attention has been
given to the assignment of index values, the biotic index will not be greatly
affected by sample size. The biotic index was calculated from:
BI = -i Eq. (1)
where n. is the number of individuals in each genus, a. is the index value
for that genus (Table III-2) and N is the total number of individuals in the
samples (14). All aquatic organisms belonging to the class Inseata and
orders Isopoda and Amphi-poda were identified to genera with the exception of
the Chi-Tonomidae . Due to time limitations only random chironomids were
selected for generic identification. For site nos. 413005, 683001, 413008
and 683002 most of the Chironomidae were Cryptochironomus and Criootopus.
The Chironomidae at these stations were considered a single taxon and
assigned a BI value of 3.5. At station 683002 the majority of the
Chir>onomi,dae were Chironomus and Glyptotendipes and were given a BI value of
5 (13).
The biotic index values, ranging from 0 to 5, can be used to evaluate
water quality and stream conditions. When the biotic index value is < 1.75,
water quality is considered excellent and the stream undisturbed. Values of
1.75 to 2.25 indicate good water quality and some enrichment. Fair water
quality is indicated by biotic index values of 2.25 to 3.00. A stream with
significant enrichment or disturbance and poor water quality has ratings of
3.00 to 3.75. If values are greater than 3.75, gross disturbance and very
poor conditions prevail (14).
Biotic index values for both artificial substrates and Surber samples
are indicative of a disturbed stream (Table III-3) . Sites 673001 and 413008
fall into the grossly disturbed category. The magnitude of disturbance at
673001 is further indicated by the high number of organisms (Table III-4) ,
particularly Glyptotendipes, a chironomid with the special ability to survive
at low oxygen concentrations. These conditions were attributed to nutrient
loadings from the fertilized cropland and golf course immediately above the
location (13). The very low numbers of macroinvertebrates at 413008 most
likely resulted from toxic creosote deposits in the bottom sediments of the
Little Menomonee River.
To simplify the complex interface between land use and water quality,
the biological program was continued by studying sites in smaller, more
contained areas of known land use. In an attempt to find a more sensitive

index summarizing community structure the information theory index of
diversity,suggested by Weber (15), was used:
_ £
d = - (N log 10 N - Zn± log 10 n±) Eq. (2)
where C = 3.321928 (converts base 10 log to base 2 log); N is total number
of individuals; and n. is total number of individuals in the itn species.
Wilhm (17) suggested index values > 3 to indicate unpolluted water and
values < 1 to indicate pollution. Diversity indices, describing macroinverte-
brate community structure, have been used to locate municipal-industrial
point sources of pollution (10). Gislason (18) used the diversity index to
define areas with point and non-point urban pollution and heavy agricultural
pesticide inputs. The goal of this project was to determine the effects of
non-point sources of pollution from individual land uses in the Menomonee
River Watershed on the macroinvertebrate communities.
Sampling Periods and Locations
During November 8 and 9, 1976 Surber samplers were used to collect
macroinvertebrates in riffle areas at station nos. 463001, 413001, 413011,
413011A and 413011B, 413006, 413006A and 413006B and 413005 ("A" indicates
a site above a water quality monitoring station, "B" refers to one below).
Sites were selected with a gradient of land uses ranging from 86% agricultural
land at site 463001 to 20% at site 413005.
At each sampling site, temperature, dissolved oxygen, current, depth and
stream width were recorded. Samples were preserved in 70% ethanol and hand-
picked using rose bengal stain to aid in differentiating the organisms from
detritus.
The Little Menomonee River agricultural sampling station (463001) had
the highest diversity value (Table III-5). Based on the classification
scheme proposed by Wilhm (17) this is the only site that can be considered
clean. The community at the next station 413011A, consisted of 90%
oligochaetes likely due to the patchy creosote deposits in the bottom
sediment. In 1973, an attempt was made to remove the creosote-contaminated
bottom sediment from the river reach between station 413011A to slightly
upstream of station 413011B. According to the U.S. EPA (7) the project was
not completely successful and the creosote deposits could be the reason for
the low diversity index value. The increase in diversity further downstream,
at station 413011B, indicates possible recovery but all stations—agricultural
and urban—showed values indicative of moderate pollution. The exception was
the urban station no. 413006B with a value of < 1. A general decrease in the
number of macroinvertebrates is evident towards the urban area except for the
two tributarieSj Noyes and Honey Creeks (Table III-5). Noyes Creek Station
(413011) contained an extremely high number of isopods (Fig. III-3 and
Table III-C-1). This phenomenon has been associated with high organic matter

content and could be related to the sewage relief pump on the south branch of
Noyes Creek. At the Honey Creek station (413006) the observed large popula-
tion was due to the abundance of oligochaetes. Other than station 413011, in
areas of the Watershed that were at least 70% urban and/or had a point source
of pollution, the samples were predominantly oligochaetes, chironomids and
gastropods (Fig. III-3).
The sampling scheme employed in November, 1976 was repeated on May 12
and 13, 1977 with two additional agricultural sites sampled on the Upper
Menomonee River (673001A and 673001).
The greatest abundance of macroinvertebrates (Table III-5) as well as
the highest diversity indices were observed at the northwest Menomonee River
agricultural stations 673001A and 673001. According to the criteria proposed
by Wihlm (17), these sites are rated as moderately polluted. The uppermost
Station (673001A) supported Baetis and Hydropsyohe (Inseota) and Chironomidae
(Fig. III-4 and Table III-C-2). Below the golf course (673001), the community
was predominantly Simulium and Dugesia (Inseata) and the pollutant tolerant
chironomid, Glyptotendipes. Half the number of macro invertebrates were found
at the Little Menomonee River upstream agricultural station (463001) compared
with the mainstem agricultural sites, but its diversity value still placed it
in the moderately-polluted category (Table III-5). The data indicates that
sites 413006 (macroinvertebrates absent), 413011 and 413006A are heavily
polluted. The low diversity and faunal abundance at 413011 may be due to the
unusually high temperature (27°C) caused by the concrete channelization pre-
ceding the station. The milky water at station 413006 at the time of sampling
suggests a point source of industrial discharge. According to the biotic
index values exceeding 3.75, all stations rated as grossly polluted.

16. ABSTRACT
The quality of runoff from nine mainstem river stations and three inner harbor
stations were monitored between 1975 and 1977. Automatic flow recording and water
sampling instruments were used at the mainstem river stations. Seasonal flow and
concentration data for 26 parameters monitored throughout the study are documented,
although discussion is focused on the key parameters — suspended solids, total-
and soluble-P and lead—to demonstrate seasonal and site differences. Bacterial
counts and PCB concentrations determined sporadically are also included. Evaluation
made on the concentration data includes 1. comparison with water quality criteria,
2. correlation to show relationships between parameters and 3. behavior of
parameter concentration and loading rates during an event.
