I. INTRODUCTION
This report presents a compilation of water quality
data collected from the various waterways within The Metro-
politan Sanitary District of Greater Chicago. The data was
primarily collected within two spans of time: May through
October 1965 and June through October 1966. The data
presented for the Calumet area is the result of a weekly
sampling program covering the period from October 1965
through October 1966. Sampling stations on the Sanitary
and Ship Canal at Lemont and Lockport provided data on a
daily basis during both 1965 and 1966. Similarly, a daily
sampling and analytical program was carried out on the
DesPlaines River at Lemont.
For the purposes of this report, the waterways
under consideration are divided into various sections as
follows:
1. The North Shore Channel (NSC), North Branch
of the Chicago River (NBCR) from Wilmette downstream to the
junction with the Chicago River.
2. The South Branch of the Chicago River (SBCR)
from the junction with the Chicago River downstream through
the Chicago Sanitary and Ship Canal (SSC) to the Lockport
-------

Locks and Controlling Works.
3. Sampling stations maintained at Lemont and
Lockport on the Sanitary and Ship Canal.
4. The waterways within the designated Calumet
area: the Calumet River (CR), Little Calumet River (LCR),
and the Cal-Sag Channel (CSC) from Lake Michigan to the
junction with the Chicago Sanitary and Ship Canal. ihis area
also includes the lower reach of the Grand Calumet River
(OCR).
5. The DesPlaines River in the vicinity of Lemon t.
Figure I is a map of the area showing a number of
the more important sampling stations. The specific locations
where data has been collected are presented in Table I for
the Main Channel system and Table 2 for the Calumet area
system. The station designations are in river miles
measured above the Lockport Controlling Works and Locks on
the Sanitary and Ship Canal.
The physical, chemical, and bacteriological analyses
included in this report were carried out, unless otherwise
indicated, in accordance with the procedures published
in "Standard Methods for the Examination of Water and Waste-
water", referred to throughout this report as "Standard
Methods".

II. MAIN CHANNEL WATERWA/ SYSTEMS
A. CHEMICAL AND PHYSICAL EXAMINATIONS
The following section covers the chemical and
physical analyses made on samples taken at various stations on
The Metropolitan Sanitary District of Greater Chicago Water-
ways System. The periods covered are from May 1965 to
October 1965 and from June 1966 to October 1966. Sampling
was carried out both by means of the District's research in-
vestigation vessel and by grab sampling from bridges.
The temperature and dissolved oxygen data are
grouped according to various monthly periods, whereas the
other chemical and physical analyses are grouped into the
yearly periods. The determinations are presented as the
algebraic means of the individual observations of each
sampling station along with the minimum and maximum values
observed for the given time periods.
The data from Lemont and Lockport has been averaged
according to the corresponding sampling periods of the other
Waterways systems and are presented in the proper figures.
A more detailed presentation and discussion of the Lemont
and Lockport data is given in a future section. The routine
-------
567
V. W. Bacon
chemical and physical examination which were made and
are presented in this section, included those for tempera-
ture, dissolved oxygen (DO), Biochemical oxygen demand
(BOD), chemical oxygen demand (COD), pH (hydrogen ion con-
centration), total alkalinity, specific conductance, organic
nitrogen, ammonia nitrogen (NHs-N), nitrites and nitrates,
turbidity, and suspended solids.
A number of mineral analyses were carried out on a
selected number of samples during 1965. These anlyses in-
cluded calcium, magnesium, potassium and sodium, In addition
the same samples were analyzed for the group of heavy metals
consisting of cadmium, chromium, copper, iron, lead, man-
ganese, nickel and zinc.
Laboratory analyses in general were made in accord-
ance to Standard Methods for the Examination of Water and
Wastewater. Measurements of temperature, specific con-
ductance, alkalinity, dissolved oxygen, ammonia, nitrite
and nitrate were carried out on the District's research
investigation vessel. The mineral constituents and the
heavy metal analyses were by atomic absorption techniques.
The results of the analyses of samples taken at the
various sampling locations are presented in Tables 3 through
5, for the North Shore Channel, North Branch of the Chicago
River, Chicago River; South Branch of the Chicago River,
-------
568
V. W. Bacon
Chicago Sanitary & Ship Canal; and the Calumet River,
Cal-Sag Channel System. These tables present the minimum,
maximum and mean values of the individual parameters
measured at each station for the two yearly periods pre-
viously discussed. The data for the individual parameters is
discussed and presented graphically in the following sections
Temperature
The average values of water temperature taken at
the time of sample collection for each of the stations during
the sampling periods designated are presented in Figures 2 to
5. Due to seasonal temperature fluctuations, the data is
divided into the following periods: May, June, 1965; July,
August, September, 1965; October, 1965; July, August,
September, 1966; and October, 1966. The mean observed
temperatures for the North Shore Channel and the North
Branch of the Chicago River are plotted in Figures 2 and 3,'
for 1965 and 1966, respectively. A rise in temperature
occurs as the water flows through the Waterway System, with
major increases in temperature occurring below the discharges
from the North Side Treatment Plant and the Commonwealth
Edison generating station at Belmont Avenue. Other tempera-
ture increases occur due to various cooling water discharges.
-------
569
V. W. Bacon
Overall, the temperature increases about two to three
degrees in the summer between Wilmette and the junction of
the South Branch of the Chicago River, and in October a three
to five degree Centigrade increase was observed.
Temperature averages for the South Branch of the
Chicago River and the Sanitary & Ship Canal during the 1965
and 1966 periods are presented in Figures 4 and 5. Here, we
see the same general trend of increasing temperatures as we
move downstream from Randolph Street (SBCR 34.45) on the South
Branch of the Chicago River to Lockport (SSC 0.18) on the
Sanitary & Ship Canal. Initially, there is a decrease in
temperature after the North Branch of the Chicago River
waters mix with the cooler Chicago River waters. Levels at
Randolph varied between 21° and 23° during the summer months
of 1966 and between 16° and 15° C. in October 1966. The
greatest increase in temperature occurred below the Common-
wealth Edison Power Plants at Throop, Crawford-Pulaski,
and Ridgeland Avenues, as well as the West Southwest dis-
charge between Central and Ridge land Avenues. It is of
interest to note that the pattern is one of a very sharp
jump in temperature in the immediate vicinity of the thermal
discharge, followed by the subsequent decline in water
temperature to a lower level, but a level which is still
higher than that previously observed above the thermal
-------
570
V. W. Bacon
discharge. The decline in temperature is most likely due to
the more complete mixing with the colder river waters and
with heat dissipation to the cooler atmosphere. After a
slight cooling effect, due to the input of the Cal-Sag Channel
waters, there is a further rise in temperature between Lemont
and Lockport. In the thirty-five (35) mile distance between
Randolph Street and Lockport, an overall rise in temperature
of 5 to 6° C was observed. Sharp monthly variations in
the water temperatures are experienced corresponding to the
seasonal ambient air temperatures. In general, the water
temperatures during the 1966 periods were two to three degrees
higher at most of the stations as compared to 1965 periods.
Dissolved Oxygen
During the warmer weather, the oxygen solubility is
decreased and the rate of biochemical oxygen consumption is
increased. Hence, the dissolved oxygen content in the river
water is influenced by the water temperatures. The DO data
was divided into the same periods as the temperature data.
The average values observed for the different periods are
shown in Figures 6 through 10 for the various waterway
systems.
The average DO profiles for the North Shore Channel
-------
571
V. W. Bacon
and North Branch of the Chicago River are shown in Figures
6 and 7 for the 1965 and 1966 periods respectively. The
dissolved oxygen levels dropped from their high values
entering at Wilmette to the lowest values at station NBCR
35.01 (Grand Avenue), just above the confluence of the
North Branch of the Chicago River and the Chicago River.
There are no apparent areas of dissolved oxygen recovery in
this stretch of the waterways. During the summer months,
when the DO level is low in the North Shore Channel immediate-
ly above the North Side Treatment Works, an initial rise in
DO occurs after mixing with the North Side Treatment Works
effluent. However, the oxygen increases are soon lost
as the waters proceed downstream. The dissolved oxygen
levels appear to start leveling off in the vicinity of mile 38
to 37, but then drop rapidly after mile 36.8. This acceler-
ation in dissolved oxygen decline coincides with the increase
in BOD and COD in this area, as presented in another section.
The lowest levels of dissolved oxygen were generally ob-
served during the warmer summer months. Between May and
September 1965, the dissolved oxygen content dropped from
an average of about 8 mg/1 at Dempster to less than 1 mg/1
in the lower region in the North Branch of the Chicago
River. In October of 1965, the decrease was from 10 mg/1
down to 2.5 mg/1, on an average basis.
-------
572
V. W. Bacon
The dissolved oxygen averages do not present a
representative picture of the oxygen levels in the North
Branch of the Chicago River. Although, on an average basis
some dissolved oxygen was observed at all sampling stations
down to the junction with the Chicago.River, there were
substantial numbers of days during the summer months in
which zero or less than 0.5 mg/1 of dissolved oxygen were
observed. Based upon oxygen content, the most critical
reach of this waterways system is a lower part of the North
Branch of the Chicago River between North Avenue and the
Junction of the Chicago River. Table 6 presents the percentage
of observations that dissolved oxygen content was equal
to or less than a stated value at several selected stations
in the lower reach of the North Branch of the Chicago River.
At station NBCR 37.53 the DO content of at least fifty
(50%) percent of the samples was less than 1.4 mg/1 in
toy, June 1965, less than 1.8 mg/1 in July through Septem-
ber, 1965, and less than 1.5 mg/1 in June-September, 1966.
Out of a total of 49 DO samples collected during May
through September, 1965, twenty-three (23%) percent con-
tained no dissolved oxygen. Further downstream the fre-
quency of anaerobic conditions was even greater. At station
NBCR 34.82, during May-June 1965, a zero DO level was
observed in 86 percent of the samples and in 55 percent of
-------
V. W. Bacon
the samples during July-September 1965. During June-
September 1966, at station NBCR 35.01, 50 percent of the
samples had DO of less than 0.5 mg/1.
Although there is no known major continuous pol-
lutional discharge between Wilmette and Oakton on the North
Shore Channel, the rate of oxygen depletion within this
reach is quite rapid, especially during the summer months.
During the period of July to September 1965, the dissolved
oxygen level dropped from 8.5 mg/1 at Linden Avenue to 4.5
mg/1 at Oakton, for a decrease of 4 mg/1 within 3.2 miles.
In 1966, the observed decrease was approximately 3 mg/1
within this reach.
The dissolved oxygen levels shown in Figure 7 and
Figure 8 are the mean values observed for the designated
periods in 1965 and 1966 on the South Branch of the Chicago
River and the Sanitary & Ship Canal. A sharp rise in DO
occurs after mixing of the oxygen depleted North Branch
Chicago River waters and the higher oxygen containing Chicago
River waters. The average DO concentrations in the Chicago
River at CR 34.78 Wells Street were 5.6 mg/1 during June to
September 1966 and 6.2 mg/1 in October 1966. At Randolph
Street, mile 34.45, the sampling station immediately below
the confluence of the North Branch and the Chicago Rivers, the
mean DO values observed were 2.4 mg/1 in May-September 1965
-------
574
V. W. Bacon
and 3.3 mg/1 in June-September 1966. The increase in
dissolved oxygen was between one to three mg/1 in DO, depend-
ing upon the relative flows and DO levels in the North Branch
Chicago River, and Chicago River. Downstream from this
station there was a resumption in the general decrease in
the dissolved oxygen to Just above the West-Southwest
Treatment Works at SSC 26.20, Cicero Avenue.
Immediately below the incoming discharge from the
West-Southwest Treatment Works, there is a sharp rise in
dissolved oxygen levels due to the addition of oxygenated
effluents and the turbulence created by the discharge into
the channel. The apparent benefit obtained by the addition
of the oxygenated discharge is lost within about three miles
below the point of discharge where the dissolved oxygen
i
levels are approximately the same as they were above the
Treatment Plant at Cicero Avenue. At Station SSC 21.98,
Lawndale Avenue, the average DO levels were 1.4 mg/1 in the
summer of 1965 and 1.9 mg/1 in October of 1965. The individual
DO concentrations varied from a minimum of 0.0 mg/1 to a
maximum of 4.7 mg/1 over the 1965 period. In the 1966
period the same approximate range was observed.
In the reach of approximately twelve (12) miles from
the Chicago River to the Junction with the Cal-Sag Channel,
the dissolved oxygen level decreased on the average from a
-------
V. W. Bacon 575
level of 2.5 mg/1 at the upstream points to less than 0.5
mg/1 at the downstream points during the summer of 1965.
During the summer of 1966, the DO decreased from an average
level of 3 to 1 mg/1. The October 1965 dissolved oxygen level
showed a decline from a value of 4.3 mg/1 at SBCR 34.^5
Randolph Street down to a level of 0.6 mg/1 at SSC 13.08 High-
way #83. Approximately the same decrease was observed in 1966.
Although the cooler periods, October 1965 and 1966, showed
higher dissolved .oxygen levels initially at the upstream sta-
tions, the downstream dissolved oxygen levels in the lower
sections of the Sanitary & Ship Canal, below mile 18.37* are
the same as the summer months, the mean values being approxi-
mately 0.5 to 1.0 mg/1. Although, on the average, the samples
taken for dissolved oxygen were 1 mg/1, this does not give a
true indication of the dissolved oxygen conditions occurring
in this reach. Table 6 presents the frequency distribution of
the observed dissolved oxygen levels during the designated
periods at various sampling stations. At Station SSC 21.98,
Lawndale Avenue, which is approximately 2.5 miles below the
West-Southwest Treatment Works outfall, during the 1965 summer
period, fifteen (15#) percent of the samples analyzed for dis-
solved oxygen were recorded as 0 mg/1; twenty-five (25#) percent
of the samples were between 0 and 1 mg/1. At Station SSC 16.8U,
Willow Springs Highway, fifty-three (53#) percent of the total
-------
576
V. W. Bacon J
observed values during June through October 1966, were
equal to or less than 1 mg/1, that is, fourteen (14) out of
thirty-six (36) observations. The June through September
period, twenty-four (24%) percent of the observations were
less than 0.5 ppm; and in October 1966, forty-five (45%)
percent were less than 0.5 mg/1. Therefore, it is apparent
that on many days during the summer periods, this reach of
six (6) miles has near anaerobic conditions occurring.
Especially true, since the DO sampling was carried out at
midstream, at between three (3) to five (5) feet below
the surface. Thus, the dissolved oxygen levels closer to
the bottom of the channel could possibly be zero on days
when the levels were only a few tenths (10th) of a mg/1 of DO
observed close to the surface. There is strong indication
that the extremely low dissolved oxygen levels are main-
tained in this area due to accumulation of organic bottom
deposits immediately upstream of this reach. This is
evident by the intensive gassification which has been
observed in the summer months and at times through the
cooler fall months.
After the confluence with the Cal-Sag Channel there
is a slight rise in dissolved oxygen level due to the higher
oxygen levels contained in the waters from the Cal-Sag
Channel. From the Cal-Sag junction downstream towards
-------
577
V. W. Bacon
Lockport the DO profile is rather flat with a slight
decrease of a few tenths of a mg/1. At Station SSC 0.18
Lockport the mean DO levels were 0.6 and 1.2 mg/1 in 1965
and 0.8 and 1.5 mg/1 in 1966. Since the mean DO values
do not give a complete evaluation of the dissolved oxygen
conditions occurring at these stations, a more detailed
discussion of the extensive sampling at Lemont and Lockport
is presented in a subsequent section of this report.
The dissolved oxygen profile which was observed
in the Calumet River, Little Calumet River and Cal-Sag
Channel system for the 1966 period is shown in Figure 10.
The dissolved oxygen content declined from the upstream
sampling station in the Cal-Sag Channel, CSC 27.99 Ashland
Avenue, to a low point in the vicinity of CSC 23.97 Cicero
Avenue, at which station the DO showed a minimum of 0.4
mg/1 and a maximum of 3.6 mg/1 with a mean of 1.6 mg/1.
Below this station a slight recovery in DO may be observed
as the waters move further downstream towards the junction
with the Sanitary & Ship Canal. Table 7 presents the
distribution of observed dissolved oxygen levels at CSC
13.11 Highway #83, on the Cal-Sag Channel. Whereas, the
range of dissolved oxygen values during July through
September 1966, was from 0.7 to 7.8 mg/1 with an average of
2.8 mg/1, fifty (50%) Percent of the values were less than
-------
578
V. W. Bacon
approximately 2.3 mg/1.
pH (Hydrogen ion concentration)
The pH results for both the 1965 and the 1966 samp-
ling periods are shown as ranges in Figure 11. Ihis Figure
represents the range of pH values observed from Wilmette
Controlling Works down through the Lockport Controlling
Works for the 1965-66 period. The data show no significant
difference in pH in the two-year period, and since an average
pH value has no real chemical meaning, only the minimum and
maximum observed values have been plotted throughout the
Waterways System. In the upper reaches of the North Shore
Channel, the water entering through Wilmette controlling
waters varied between 8 and 8.7 pH units. The sharpest
decrease in pH occurs after mixing of the North Shore
Channel with the North Side Treatment Works effluent. Below
the North Side Treatment Works outfall the pH varied between
6.9 and 7.5 and remained in this range down to the confluence
with the Chicago River. With the input of the slightly
higher pH of the Chicago River waters, there is a slight
increase in pH at Randolph Street. Below this point in the
rest of the waterways system down to Lockport, the pH was
maintained between 7 and 8.0, the median value being 7.3.
-------
V. W. Bacon 579
Lower pH values in general were observed during May and
June as compared to the later summer and fall months.
Total Alkalinity
The total alkalinity values plotted in Figure 12
represents a mean value of the alkalinity determinations per-
formed on samples collected in July and August 1966.
These results represent between 4 to 8 determinations
made at the various sampling locations, and are expressed
in terms of CaCO3. The alkalinity as reported coming in
through the upper part of the North Shore Channel has a
mean value of 20 mg/1. Alkalinity slowly rises as the water
moves downstream, and a sharp increase occurs in the vicinity
of Station NBC 37.53 Ashland Avenue. At this sampling
station the mean alkalinity was approximately 170 mg/1.
The aIkaUnities range between 150 and 170 all the way down
to the junction with the Chicago River. The Chicago River
waters at sampling Station CR 34.78, Wells Street, exhibited
a mean alkalinity of 130 mg/1. Upon mixing of the Chicago
River waters and the North Branch of the Chicago River
waters, the resulting alkalinity is decreased to 143 mg/1 at
SBCR 34.47 Randolph Street.
Below Station SBCR 34.47 the alkalinity decreased
-------
580
V. W. Bacon
to a low mean value of 130 mg/1 at SB OR 30.55 Ashland
Avenue. This decline was followed by an increase to a mean
of about 160 mg/1 at the sampling station located below the
West-Southwest Treatment Works discharge. There is a con-
tinual rise in alkalinity down toward the Cal-Sag junction.
At Station SSC 15.84, Willow Springs Highway, the alkalinities
reached a level of 182 mg/1.
Biochemical Oxygen Demand (BOD)
Determinations of the 5-day BOD's were carried out
on samples at selected stations along the waterway system.
The number of samples analyzed during the periods in 1965
and 1966 varied from six to twenty-five determinations,
depending upon the sampling station. The average values
of 5-day BOD observed during the 1965 and 1966 periods are
presented in Figure 13. The waters entering the North Shore
Channel as measured at sampling Station NSC 49.89, Linden
Avenue, showed an average BOD of 2 mg/1 in the summer period
of 1966. An increase in the BOD level occurred as the waters
flowed downstream, with values of 6.0 mg/1 at NSC 47.05
Dempster in 1965 and 3.8 mg/1 found at Oakton in 1966.
Below the North Side Treatment Works, the BOD increased
by 1 to 1.2 mg/1, to levels of 7.6 mg/1 in the 1965 period
-------
V. W. Bacon ^
and 4.9 mg/1 in the 1966 period at NSC 45.06, Touhy Avenue.
At this station individual values as high as 16 mg/1 were
found.
From Station NSC 45.06 the BOD generally decreased
until the vicinity between mile 37.98 and 37.53 where the
BOD increased to an average value of 8.0 mg/1 (during the
1965 period) and 6.2 ing/1 (in the 1966 period) respectively.
The increased BOD also coincides with increased COD con-
centration in the area. This increase of approximately
2 mg/1 indicates the addition of an organic waste which is
probably the discharge from the Medill Incinerator Plant. It
should be noted that construction plans have been formalized
and this source of waste will soon be removed from the water-
ways to a sewer. The BOD then decreased downstream to
averages of 5.0 mg/1 at NBCR 34.82 in the 1965 period and 4.6
mg/1 at NBCR 35.01 Grand Avenue in the 1966 period.
The thirteen samples collected from July through
October 1966 of the Chicago River waters at CR 34.78 Wells
Street had a BOD ranging from 0.9 to 7.7 mg/1 with a mean
of 3.1 mg/1.
Below the confluence of the North Branch Chicago
River and the Chicago River, the BOD averaged 5.0 mg/1 at
SBCR 34.25 Madison (1965 period) and 3.6 mg/1 at SBCR
34.45 Randolph (1966 period).

Chemical Oxygen Demand (COD)
The mean values of the chemical oxygen demand
determinations at the various sampling locations through
the waterways system, which were conducted during the 1965
and 1966 season, are presented graphically in Figure 14.
During the 1966 season the average COD levels for the
North Shore Channel waters above the North Side Treatment
Works, ranged between 14 and 18 mg/1. In 1965 at sampling
location NSC 47.05, Dempster Avenue, the COD average was
33 mg/1, with a range of 7 to 64 mg/1 for seventeen (17)
determinations. The COD levels increased rapidly immediate-
ly below the discharge from the North Side Treatment Works
at NSC 45.06, Touhy Avenue, levels of 52 mg/1 in 1965 and
36 mg/1 in 1966 were observed. A single maximum value of 120
mg/1 occurred in the 1965 samples. These levels represent
an increase of approximately 20 mg/1 on the average over the
upstream sampling station. Below this location a slight
decline in the COD concentration was evident followed by
another sharp rise in the vicinity of mile 37.98 and mile
37.53. The mean value in the 1965 period at NBCR 37.98
was 59 mg/1 and in 1966 was 45 mg/1. This coincides with
the observed increase in BOD at this point. This area is
also where the increase in the rate of dissolved oxygen
-------
583
V. W. Bacon
decline occurred, as mentioned in the previous section.
An individually high COD value of 99 mg/1 was measured at
Station NBCR 37.53, Cortland Avenue, during the 1966
season. The COD then decreased again to a level of 47 and
38 mg/1 in 1965 and 1966, respectively, in the lower
portion and North Branch of the Chicago River.
The Chicago River waters entering below this
point had COD values ranging between 4 and 48 mg/1 with a
mean of 22 mg/1 at sampling station CR 34.78, Wells Street.
Moving down through the system to sampling location SSC
26.20, Cicero Avenue, which is just above the West-South-
west Treatment Plant Works, the COD levels were 34 and 38
mg/1 in 1965 and 1966, respectively, ranging from a low of
12 mg/1 up to 76.mg/1, maximum. The levels increased
upon.addition of the West-Southwest effluent to an average
level between 43 and 45 mg/1 in the reach between Harlem and
Lawn dale Avenues. Further on downstream, the COD results
fluctuated widely, and at sampling Station SSC 16.84,
Willow Springs Highway, the range of values observed was
from 27 up to 45 mg/1, with a mean of 35, in the 1965
period, and in 1966 ranged from 28 to 71 mg/1 with an
average of 44 mg/1.
Below the Cal-Sag junction, the COD values declined
with an average at SSC 9.51 Lemont from June-October 1966
-------
584
V. W. Bacon
of 27 mg/1. There was only a slight change in this level
as the water reached Lockport where the average COD for the
corresponding 1966 period was 30 mg/1. The COD determina-
tions give no indication of any great increases in organic
material between the Lemont and Lockport sampling stations.
This is contrary to the observed BOD results, but as dis-
cussed in another section, the high apparent BOD values ob-
served at Lockport are probably due to nitrification
occurring in the laboratory bottles. The waters of the
Cal-Sag Channel showed a mean COD in the 1966 season of
45 mg/1 at CSC 13.11 Highway #83, just above the confluence
with the Sanitary 8s Ship Canal.
Organic Nitrogen
The averages of the organic nitrogen determinations
made during the periods indicated are plotted in Figure 15.
The organic nitrogen levels in the upper reaches of the
North Shore Channel fluctuated from individual low values
of 0.1 mg/1 to as high as 6.6 mg/1 with mean values of
2.6 mg/1 observed at NSC 47.05 Dempster in the 1965 period
and of 0.8 mg/1 at NSC 46.05 Oakton during the 1966 period.
At Station NSC 45.06 Touhy, below the North Side Treatment
Works, the averages increased to 3.2 mg/1 during the 1965
-------
V. W. Bacon ^ ^
period and to 2.2 mg/1 during the 1966 period. From this
point downstream the levels varied, but showed a general
decline to 1.0 mg/1 at SBCR 30.55 Ashland Avenue on the
South Branch of the Chicago River. At the next downstream
station SBCR 26.20 Cicero Avenue the average was 1.8 mg/1.
The data for July-October 1966 showed the organic nitrogen
levels remaining rather constant down through the North
Branch of the Chicago River. Below the confluence with the
Chicago River the values declined to 1.6 mg/1 at SBCR 26.20
Cicero Avenue.
With the addition of the West-Southwest effluent
the organic nitrogen increased to averages of 5.5 mg/1 in
1966 period and 3.0 mg/1 in the 1965 period at the down-
stream stations. Below this point the 1966 data showed a
rapid decrease occurred to 1.1 mg/1 at SBCR 16.84 Willow
Springs, then increased to about 2.0 mg/1 for the rest of
the reach down to Lockport.
Ammonia Nitrogen
Figure 16 presents the ammonia nitrogen averages
of the various waterway sampling stations during the
indicated periods. The ammonia data for the 1965 period
represents from 22 to 27 determinations whereas the 1966
-------
V. W. Bacon 586
period contains 6 to 24 determinations at the various
stations. The data from both periods followed the same
general pattern with the 1965 values being slightly higher
in certain sections of the waterways.
Above the North Side Treatment Works in the North
Shore Channel the ammonia values varied between 0.1 and
1.5 mg/1 with averages of 0.4 to 0.5 mg/1. Below the
North Side Treatment Works, at. Station NSC 45.06, the
ammonia rose to 4.3 mg/1 in the 1965 period and 4.6 mg/1
in the 1966 period. Values as high as 8.3 mg/1 were ob-
served at this location. Downstream from this station the
levels continued to a high of 5.5 mg/1 at NBCR 38.37
Fullerton Avenue.
Upon mixing with the incoming Chicago River
waters the ammonia dropped sharply to an average of 3.8
mg/1 at Station SBCR 34.45, Randolph Street. The Chicago
River waters at CR 34.78 had ammonia averages of 2.7 mg/1
in the 1965 period and 1.3 mg/1 in the 1966 period. Below
the confluence of the North Branch of the Chicago River
and the Chicago River the ammonia concentrations con-
tinued in general to decline downstream to an average low
of 3.0 mg/1 at SSC 26.20 Cicero Avenue.
Downstream of the West-Southwest Treatment Works
the average ammonia concentrations ranged from 7.4 mg/1 to
-------
V. W. Bacon 58?
6.3 mg/1 in the 1965 period and between 5.4 mg/1 and 6.6
mg/1 during the 1966 period. In the Sanitary & Ship Canal
from SSC 9.51 Lemon t to SSC 0.18 Lock port the ammonia levels
were about 4.3 mg/1 during the 1966 period.
Hitrite-Nitrate
The average concentrations of nit rite-nitrate during
May through October 1965 are plotted in Figure 17. The
levels in the North Shore Channel above the North Side
Treatment Works ranged from less than 0.2 to 0.35 mg/1.
Just below the North Side Treatment Works, the average
concentrations increased to 1.71 mg/1. After remaining
rather constant, between 1.4 and 1.6 mg/1, the concentra-
tions started increasing at NBCR 38.37 and continued to
rise to a peak of 2.64 mg/1 at NBCR 36.85, North Avenue.
Thereafter, the concentrations decrease to 2.0 mg/1 just
above the confluence with the Chicago River.
The Chicago River waters at CR 34.78, Wells Street,
contained values ranging from 0.2 to 1.8 mg/1 with an
average of 0.6 mg/1.
In the reach from the confluence of the Chicago
River down to station SSC 26.20 on the Sanitary and Ship
Canal, the levels varied between 1.0 and 1.6 mg/1. With
-------
V. W. Bacon 588
the addition of the West-Southwest Treatment Works effluent,
the nitrite-nitrate levels decreased from 1.4 mg/1 to 0.9
mg/1.
Suspended Solids
The results presented in Figure 18 represent the
averages of the observed values for suspended solids at the
sampling stations along the Main Channel. The samples were
collected during the period from May to October 1965 and
the number of determinations varied between 6 to 20 depending
on the sample location. The only suspended solids data
available in 1966 are the determinations carried out on
samples at Lemont and Lockport sampling locations on the
Sanitary & Ship Canal. The suspended solids averages
fluctuate between 15 mg/1 and 55 mg/1 throughout the water-
ways system. There is a general pattern of decrease con-
centrations in the suspended solids at those sampling sta-
tions immediately below the major treatment plant discharges.
This occurred both below the North Side Treatment Works on
the North Shore Channel and below the Southwest Treatment
Plant on the Sanitary and Ship Canal. At NSC 46.05, Oakton
Street, on the North Shore Channel, the sampling location
above the Nortfeside Treatment Plant, the suspended solids
-------
589
V. W. Bacon
coocentratiODs were 50 mg/1. Subsequently, after mixing
with the treatment plant effluents, the suspended solids
at NSC 45.06, Touhy Avenue, were found to be 30 mg/1. At
Cicero Avenue, the sampling station located above the dis-
charge from the rfest-Southwest Treatment Works, the suspended
solids levels averaged 37 mg/1. Below the West-Southwest
discharge, the suspended solids averaged 12 mg/1 at Lawn-
dale Avenue. This decrease in suspended solids below the
Treatment Plant discharges is probably due to the occurrence
of a natural flocculation upon mixing of the river waters
and the treated effluent, and the subsequent settling of
what was finer, colloidal suspended materials in the river
water, as well as in the plant effluents. The suspended
solids then gradually declined in the lower reach of the
Sanitary & Ship Canal from a level of about 23 mg/1 at
Lemont to 18 mg/1 at Lockport.
Turbidity
Between June and October 1965, turbidity measure-
ments were conducted on the many samples taken in the water-
ways system from NSC 49.89, Linden Avenue, on the North
Shore Channel down to Willow Springs Road on the Sanitary
& Ship Canal. These values of the observed turbidity
-------
590
V. W. Bacon
measurements are shown in Figure 19. The turbidity levels
follow the same general pattern as that of the suspended
solids. The turbidity fluctuated between 2 and 21 JC units
down through the system, with definite decreases in tur-
bidity occurring below the discharges from the major
treatment plants. The North Shore Channel, upstream from
the North Side Treatment Plant, had turbidity values
which ranged between 14 at Linden Avenue to 21 at Oak ton
Street. At sampling station NSC 45.06, Touhy Avenue,
below the Northside Treatment Works, the turbidity was 13.
The turbidity fluctuated but, in general, declined as it
moved down in the North Shore Channel and through the
North Branch of the Chicago River, reaching levels of about
12 in the vicinity of NBCR 35.01, Grand Avenue, on the lower
reach of the North Branch of the Chicago River. From SBCR
34.45, Randolph Street, on the South Branch of the Chicago
River, just below the junction with the Chicago River, down
to SSC 26.20, Cicero Avenue, the sampling location just
above the West-Southwest Treatment Plant, the turbidity
fluctuated between 12 and 17. At the Cicero sampling loca-
tion, the average turbidity was 15. After mixing with the
West-Southwest effluents, the turbidity of the water started
to decline to values of 11 at SSC 22.98 down to a low of
7 at SSC 18.37, U. S. Highway #45.

Specific Conductance
The specific conductance of a water sample is
related to the concentration of the dissolved ions contained
within the sample. Specific conductance readings were made
aboard the patrol boat as it moved through the waterways
system on a given sampling date. Mean values for the May
through October 1965 period and July through October 1966
period in the North Shore Channel, North Branch of the
Chicago River are plotted in Figure 20. The conductivity
levels followed the same general patterns during both
i
periods with the 1966 values being slightly lower in cer-
tain areas. Conductivity of the water entering the North
Shore Channel remained at a level of 270 pmhos/cm. After
addition of the effluent from the North Side Treatment
Works, the conductivity rose sharply to an average of 520
and 490 at NSC 45.06, Touhy Avenue, respectively. Below
this station, a gradual rise occurs as dissolved solids
are added to the water flowing downstream. A high of about
570 is reached at sampling location NBCR 37.98, Ashland
Avenue, on the North Branch of the Chicago River. Just
above the junction of the Chicago River and the North
Branch of the Chicago River, the conductivity drops off
to 540 in the 1965 period and 510 in the 1966 period. The
-------
592
V. W. Bacon
conductivity at Wells Street of the Chicago River waters
are in the range of 370 in 1965 and 345 in 1966.
Figure 21 presents the mean conductivity values
found in the South Branch of the Chicago River and the
Sanitary & Ship Canal for the two periods indicated. With
the addition of dilution water from the Chicago River, the
conductivity dropped to an average level of 450. Con-
ductivity then showed a varying but steady increase to an
average level of 460 in 1965 and 510 in 1966 at SSC 26.20,
Cicero Avenue, A sharp rise occurred with the addition of
the West-Southwest effluent, with the conductivity increasing
to levels of 625 in 1965 and 595 in 1966, in the vicinity
of Harlem Avenue and Lawndale Avenue. Thereafter, a gradual
increase in conductivity results as the waters flow down-
stream reaching a level of 700 in 1965 and 650 in 1966 at
SSC 0.18, Lockport sampling station during the summer
months. The 1966 values are approximately 50 ^mhos/cm lower
in various reaches of the waterways system, as compared to
the 1965 periods. The North Branch of the Chicago River at
NBCR 37.55, Cortland Avenue, the conductivity range was from
380 to 655, with a mean value of 520 in 1966. However, in
1965, for the May through October period, conductivity
ranged from 400 to 825 with a mean of 570. The higher
conductivities *ere mainly observed in May 1965, ranging
-------
V. W. Bacon
between 520 and 800 for a mean of about 620, which accounts
partially for the higher conductivity levels observed in 1965
as compared to 1966. Similarly, high values in the lower
region of the Sanitary & Ship Canal may be attributed to the
high values which occurred during the May period. At the
Lemont sampling station, the May mean value was 830 in
1965. The mean value from June through October 196E
would be only 710, which would compare with the 700 value
observed for the July through October period in 1966.
Minera1 Const it ueots
The mineral constituents in the water, including
calcium, magnesium, potassium and sodium, were measured in
a number of river samples taken from various locations
along the waterways system from the North Shore Channel
down through the Sanitary & Ship Canal to Cal-Sag junction.
Samples were taken during the months of September and October
1965 at the upper part of the system, and between July
through December, at the lower end of the Sanitary & Ship
Canal. Table 8 shows the concentration of the constituents
found at the various sampling locations. Calcium and mag-
nesium constitute the quantity in water known as hardness.
The average observed values are plotted in Figure 22 for
-------
V. W. Bacon
the overall main channel system. At Station NSC 49.91,
Isabella Avenue, on the North Shore Channel, the calcium
values ranged from 36.5 to 46.3 rag/I, with the magnesium
values ranging between 10.1 and 13.2 mg/1. These con-
stituents increase to a level for calcium of 35.0 to 56.8
mg/1, and for magnesium, 12.9 to 22.4 mg/1, at the sampling
station just above the junction with the Chicago River. In
the fifteen-mile distance from Isabella Avenue down to
the junction with the Chicago River, the Calcium concen-
trations on the average increased by 6 ppm and the magnesium
concentrations increased by 6.3 mg/1. The major percentage
of this increase was due to the discharge coming into the
North Side Treatment Plant at mile 44.0.
Potassium levels observed in North Shore Channel
waters were in the range of 1.15 to 1.50 above the North
Side Treatment Works. Immediately below the treatment
plant discharges, NSC 44.06, Touhy Avenue, the average
concentration increased to 4.85 mg/1 and continued to
increase only slightly as the water moved downstream
towards the Chicago River, resulting in an average con-
centration of 5.42 mg/1 at Kinzie Avenue. Sodium values
follow the same pattern, with the mean value in the upper
part of the North Shore Channel being 3.7 mg/1. The sodium
concentrations increase greatly at NSC 44.06, Touhy Avenue,
-------
V. W. Bacon 595
to a level of 27.8 mg/1, and then increase slowly to a
final level of 31.7 mg/1 at NBCR 34.82, Kinzie.
Table 9 presents the minimum, maximum and mean
values observed at the sampling stations along the South
Branch of the Chicago River and Sanitary & Ship Canal for
calcium, magnesium, potassium and sodium. From the sampling
station just below the junction of the North Branch of the
Chicago River, SBCR 34.27, the calcium concentrations
increased from a mean value of 48.1 mg/1 to a mean value of
57.2 mg/1 at SSC 27.27, Pulaski, Below this station down
to Lockport, the average concentration varied between 50 and
56 mg/1. The magnesium values increased by about 3 mg/1
from an average of 16.8 mg/1 at the confluence of the Chicago
River (SBCR 34.27) to 19.5 mg/1 at SSC 0.18, Lockport.
The concentrations of magnesium varied between 12 mg/1 and
25 mg/1 throughout the Sanitary & Ship Canal from Madison
to Lockport. It may be noted that no appreciable rise
occurred below the West-Southwest Treatment Works, indica-
ting the same concentration levels in the plant effluent.
The concentration of potassium increased from the
SBCR 34.27 mean value of 5.33 mg/1 to a mean value of
6.9 mg/1 at Lockport. The major portion of this increase
is observed below the Southwest Treatment Works. Similar-
ly, the sodium concentrations follow the same general
-------
596
V. W. Bacon
pattern increasing from a mean value o:f 32.6 mg/1 up to
44.4 mg/1 downstream at the Lock port sampling station.
Heavy Metals
During 1965, in the months of September and
October, samples for analyses of the heavy metals were
taken from selected stations, along the North Branch of
the Chicago River, the South Branch of the Chicago River,
and the Sanitary & Ship Canal. At the lower end of the main
channel system, sampling was conducted from July through
December 1965, at stations: Willow Springs, Lemont,
Lockport, on the Sanitary & Ship Canal, and Highway 83 on
the Cal-Sag Channel. Heavy metals were measured in a number
of samples to ascertain if any one of them might be found
in significant concentration. The heavy metals which were
analyzed, included chromium, manganese, nickel, copper, zinc,
cadmium and lead. Those metals which were found in de-
tectable amounts are shown in Table 10 for the North Shore
Channel and North Branch of the Chicago River and in Table
11 for the South Branch Chicago River and Sanitary & Ship
Canal. The tables present the number of samples in which
the observed values were above the detection limits out
of the total number of samples analyzed. Wherever the
-------
597
V. W. Bacon
metals were above detectable limits, the range of values
is presented. At all sampling locations the concentrations
of chromium, nickel, cadmium and lead were not found to be
above the detection limits of .02, .03, .01 and .10 mg/1,
respectively, in all samples examined. One out of 42
samples taken from various locations on the N0rth Shore
Channel and the North Branch of the Chicago River gave
values of copper above the detection limit of 0.03 mg/1.
Individual high value of 0.7 mg/1 was found in one instance.
Only five samples out of 52 samples were found to contain
any traces of copper from the lower reach of the Sanitary
& Ship Canal at Lemont Road and Lockport. The values
ranged from below detection limits to 0.18 mg/1. The rest
of the sampling station locations on the South Branch of
the Chicago River and the Sanitary & Ship Canal were below
detection limits of 0.03 mg/1. Zinc was found at all
stations where samples were taken. Concentrations varied
from below the detection limit of 0.01 mg/1 up to a
maximum value of 0.18 mg/1, the maximum value being ob-
served at SSC 27.27 on the South Branch of the Chicago
River. The mean value at thte station was 0.07 mg/1.
Manganese was found in measureable amounts at all the
sample locations, ranging from below the detection limit of
0.02 mg/1 to a maximum of 0.10 mg/1. The mineral analyses

which were determined on samples from the Calumet River,
Little Calumet River, are presented in the section covering
the Calumet area surveillance data.
B. BACTERIOLOGICAL EXAMINATION OF WATER QUALITY
The bacteriological data presented in this section
was obtained from sampling at the various locations in the
waterway systems during September and October 1965 and
from July to October of 1966. Total coliform and fecal
streptococci densities were determined on all bacteriologi-
cal samples collected. Fecal coliform determinations were
made on many samples taken during the 1966 periods.
Presentation of the data is divided into the three major
sections of the waterways system: (1) Nbrthshore Channel,
North Branch of the Chicago River, (2) South Branch of
Chicago River, Chicago Sanitary and Ship Canal and (3) The
Calumet River, Oil-Sag Channel. The results are expressed
in terms of the geometric mean count per 100 ml as well as
the minimum and the maximum values of the individual obser-
vations. The total coliform densities were determined by
a membrane filter technique as described in "Standard
Methods". The membrane filter technique was also used
in the determination of the fecal streptococci using KF
-------
V. W. Bacon 599
streptococci broth. Fecal coliform counts were by a mem-
brane filter technique using MSC media as per "Standard
Methods"
North Shore ChapDOI. North Branch of the Chicago River and
Chicago River Systems.
Table 12 presents a summary of the total coliform
densities at the sample location along the North Shore
Channel - North Branch Chicago River. The data is presented
for September, October 1965 and July through October 1966.
A comparison of the geometric means of the total coliform
densities found in 1965 and 1966 periods are plotted in
Figure 23. Fig;ure 24 is a plot of the minimum, maximum
and geometric rnean total coliform values observed during
the 1966 period.
In th.e upper reaches of the North Shore Channel,
above the Northside Treatment Works, the geometric mean
values increased from about 300 per 100 ml at Linden NSC
49.89 to about 6,000 per 100 ml at Oakton NSC 46.05 which is
Just above tltie Northside Treatment Works. An individual
high of 90,000 per 100 ml was observed during October 1965
at Central Avenue NSC 49.23. Just below the Northside
discharge at station NSC 45.06 the total coliform densities
-------
V. W. Bacon 600
Increased to about 111,000 per 100 ml in 1966 and 134,000 per
100 ml in 1965. This is an increase of approximately 20 times
over the upstream sampling point. Below the Northside Treatment
Works the total collform densities generally increased moving
downstream with minor fluctuations, to a high of about 920,000
per 100 ml at station NBCR 36.32 - Division Street in September,
October of 1965. This was followed by a decline to a level of
about 545,000 per 100 ml, Just above the Junction of the North
Branch and the Chicago Rivers at station NBCR 34.82. During the
summer period of 1966 the general increase in total conforms in
the vicinity of NBCR 37.98, Ashland Avenue to NBCR 36.32, Divi-
sion Street was not observed. The range of counts increased
from 110,000 per 100 ml at Touhy to about 210,000 per 100 ml at
Damen. It then declined to about 90,000 per 100 ml at Grand,
NBCR 35.01. Individual values as high as 7.2 and 7.4 millions
per 100 ml were observed at NBCR 36.32 and NBCR 35.90 during the
1965 period. These counts were observed on days following heavy
storms. For the summer period of 1966 the maximum value was 3.1
million per 100 ml detected at station NBCR 35.41 and NBCR 35.01.
The intermediate high values in 1965 may be due to intermittent
combined sewer discharges occurring during this period.
The results of fecal coliform examinations during
the 1966 period are presented for the individual stations
in Table 13. The minimum, maximum and geometric mean values
are given to illustrate the variations at the individual
sampling points and are plotted in Figure 25. The same
-------
V. W. Bacon 6o1
general trend was observed for fecal coliform as was shown
for the total coliform. At Linden Avenue, NSC 49.89 low
values are observed varying between less than 10 and 300.
There was an initial rise in fecal coliform density down to
the Northside Treatment Plant. Below the Northside Treat-
ment Plant the fecal coliform densities jumped up to a
level of about 30,000 per 100 ml at NSC 45.06. A slight
decline in densities occurs below the junction at North
Branch of the Chicago River in the North Shore Channel.
The levels are approximately 25,000 per 100 ml at Argyle,
North Branch CR 42.26. Below this junction point the
fecal coliform geometric means varied between 40,000 and
70,000 per 100 ml with a general increase at Cortland,
NBCR 37.50. At the sampling station (NBCR 35.01) just
above the junction of the Chicago and the North Branch Chica
go Rivers the fecal coliform mean values drop to 17,000 per
100 ml.
A summary of the fecal streptococci densities
found during the September, October 1965 period and during
the July to October 1966 period is presented in Table 14.
The geometric mean values observed during the two periods
are compared in Figure 26, and Figure 27 shows the minim urns,
maximum, and the geometric means of the observed fecal
streptococci values for 1965. Similar to the pattern of
-------
602
V. W. Bacon
the total coliform densities we observe that the fecal
streptococci averages are lower in September and October
1965 as compared to July through October 1966 in the lower
reaches of the North Branch of the Chicago River. Moving
downstream through the North Shore Channel the densities
increased from a level of about 200 per 100 ml above the
Northside Treatment Works at NSC 46.05 to a level of about
4,000 per 100 ml at the downstream station NSC 45.06
Touhy. This is a twenty fold increase in density. Between
stations NSC 45.06 and NBCR 37.98 during 1965 period the
level of fecal streptococci varied between 3500 and 2500
per 100 ml and then slowly decline to about 900 per 100 ml
at Grand, NBCR 35.01, just above the confluence of the
Chicago River. Comparison with the September, October 1966
data shows that the fecal streptococci densities continued
generally to increase to a level of about 26,000 per 100 ml
between mile 36.85 and 36.32 and then dropped off to 20,000
at Kinzie Avenue, NBCR 34.82.
The ratio of total coliform to fecal streptococci
densities fluctuated for the individual observations. On
the average, during the 1966 period, at Touhy Avenue,
NSC 45.06 just below the Northside Treatment Plant the
ratio was about 35 to 1 whereas, in the lower reaches of
the North Branch Chicago River the ratio of total coliform
-------
603
V. W. Bacon
to fecal streptococci is between 60 and 70 to 1.
The results of the total coliform, fecal coliform
and fecal streptococcus examinations for 1966 have been
plotted for the Chicago River in Figures 31, 32 and 33
respectively. In the Chicago River, just before the junc-
tion of the South Branch and the North Branch of the Chicago
Rivers at CR 34.78 Wells Street, the mean total coliform
densities found were 28,000 per 100 ml in 1965 and 3,300
per 100 ml in 1966. The fecal streptococci densities were
450 per 100 ml in 1965 and 135 per 100 ml in 1966. The com-
parison Is between 7 samples taken during the months of
September, October 1965 and 12 samples taken over July
through October in 1966. In the 1965 period a high result of
63,000 total coliform per 100 ml accounted for the high
average. If this result were omitted the geometric mean
would be 8,000 per 100 ml.
Rranch of The Chicago River and Chicago Sanitary and
Ship Canal
Bacterial analyses on samples from this section
on the waterways were only carried out during the July to
October period in 1966. Table 15 present the minimum,
maximum and geometric mean values of the total coliform

V. W. Bacon
counts per 100 ml observed in this part of the waterway
system. ID the reach from the Junction of the Chicago and
North Branch of the Chicago Rivers down to just above the
West-South West Treatment Works (Cicero Avenue, BCR 26.20)
the general level total coliform densities fluctuated be-
tween 9,000 and 41,000 per 100 ml. A sharp increase in
coliform densities occurs at the sampling locations below
the West-Southwest Treatment Works discharge. Between
station SSC 22.38 and station SSC 16.84, a distance of
about 5.5 miles, the coliform counts range between 200,000
and 430,000 per 100 ml based on the geometric means. Most
significant were the counts that were observed at the
Harlem Avenue station SBCR 22.98 about 2.5 miles below the
main discharge. At this location the coliform geometric
mean was only 110,000 per 100 ml, relatively lower than the
next few downstream stations. These levels increased two
to threefold at the next several downstream sampling stations
Similar results were observed for fecal coliform. Below
SSC 18.37, which is about 6 miles below the Southwest Treat-
ment Works discharge the total coliform densities pro-
gressively decreased to a low geometric mean value of about
17,500 per 100 ml at SSC 5.18. The Calumet Sag-Channel
comes into the Sanitary and Ship Canal at mileage point
12.48 whereupon a substantial drop in density occurs at
-------
605
V. W. Bacon
the next downstream station, due to the lower total coliform
density of the Cal-Sag waters.
The individual total coliform counts ranged from
a low of less than 1,000 per lOO ml at several sampling
stations to a high value of 5.7 million per 100 ml.
The Harlem Avenue sampling station showed in itself great
variation in total coliform counts. The range going from
less than 1,000 to a maximum 5,700,000 per 100 ml with a
geometric mean of 110,000 per 100 ml.
The fecal coliform densities observed during the
1966 sampling period are presented in Table 16 for the
South Branch of the Chicago River and the Sanitary and
Ship Canal, and are plotted in Figure 32. The fecal coli-
form densities follow the same trend as the total coliform
densities, only with a value of 12,600 per 100 ml down to
a low value of 4,500 per 100 ml at Cicero Avenue. A sharp
rise was observed at the sampling stations downstream of the
Southwest Treatment Works discharge. However, the maximum
mean values were not obtained until between stations
SSC 22,38 and SSC 18,37. At Harlem Avenue SSC 22.98 the
fecal coliform densities ranged from less than 100 to a
maximum of 1.2 million per 100 ml, with a geometric mean
density of 26,400 per 100 ml. At I*wndale Avenue SSC
21.98, one mile below Harlem Avenue, the minimum value
-------
V. tf. Bacon
was 3,000 and the maximum value was 1.2 million per 100 ml,
with a geometric mean of about 80,000 per 100 ml. Similar
to the total coliform densities the levels which would be
anticipated below a major waste treatment plant discharge
which was not chlorinated, do not generally occur until one
to two miles further downstream. Incomplete mixing may
account for some of the discrepancies in the counts at the
Harlem Avenue stations. However, the results of a limited
number of cross-sectional sampling for total coliform as
well as fecal coliform at this station showed no significant
differences in counts from six points taken within the cross
section. These limited results indicate that there is per-
haps some constituent or toxic material in this immediate
area which is contributing to either an inhibitory effect
upon the total coliform and fecal coliform organisms or is
perhaps interfering with the coliform test itself.
After mile 13.08 the fecal coliform densities
gradually decreased from a geometric mean value of 90,000
per 100 ml to a geometric mean low of 2,000 per 100 ml
eight miles downstream. The last sampling station SSC 5.18
Romeo Highway, however, had only 6 samples taken during the
period of study. The range of counts varied from a minimum
of 110 per 100 ml up to a maximum of 32,000 per 100 ml.
The fecal streptococcus results are presented in
-------

V. W. Bacon
Table 17 for those sampling stations on the South Branch
of the Chicago River and the Sanitary and Ship Canal. The
minimum, maximum, and geometric mean observed values have
been plotted in Figure 33. In the reach from the junction
with the North Branch of the Chicago River down to the
sampling station just above the Southwest discharge at
Cicero Avenue SSC 26.2 the fecal strep densities ranged
between less than 100 per 100 ml to approximately 500 per
100 ml. A sharp rise in fecal streptococci counts occurs
below the discharge of the West-Southwest Plant at SSC 22.98,
Harlem Avenue. The values range between less than
10 and 120,000 per 100 ml with a geometric mean of about
13,600 per 100 ml. From this high point the densities
decreased progressively as the water moved downstream
reaching a low value of 137 per 100 ml at the Romeo
Highway.
Calumet River, Little Calumet River and Cal-Sag Channel
System
Table 18 summarized the total coliform densities
observed within the Calumet River, the Little Calumet River,
and the Cal-Sag Channel waterways. The samples for these
analyses were taken mainly from the District boat and do
-------

V. W. Bacon
not include the results of the regular Calumet Area
Surveillance sampling program in the Calumet River and Little
Calumet River (presented in section III). Comparison of
the data showed very little difference between the bacterio-
logical values obtained in the two different sampling pro-
grams. In order to obtain an overall indication of the
bacteriological quality of these river systems, all the
data gathered between July and October 1966 was used in
computing the geometric means which are plotted in Figure 18.
In the Calumet River the observed geometric mean total
col if or m densities fluctuated between 300 and 3,000
counts per 100 ml, with individual observations as high as
140,000 counts per 100 ml being noticed in certain samples.
A sharp increase in total coliform counts occurred below the
discharge of the Calumet Treatment Works. The sampling
station immediately below this point Is station LCR 21.02,
HaIsted Street. The mean values increased from a level of
3,200 per 100 ml upstream of the treatment plant discharge
to a level of 309,000 per 100 ml downstream of the treat-
ment plant discharge. From this point on the Little Calu-
met River the levels of total coliforms remained nearly
constant down through the Cal-Sag Channel at a value of
about 2pOO,000 per 100 ml until station CSC 19.78, South-
west Expressway. Below this point as the waters move
-------
V. W. Bacon °9
downstream the total coliform densities died off to a level
of about 11,000 counts per 100 ml at station CSC 13.11,
U. S. Highway 83, which is located just above the junction
with the Sanitary and Ship Canal.
The fecal coliform densities observed during the
period of June to October 1966 are presented in Table 19, the
minimum, maximum, and geometric mean values are plotted in
Figure 35. The range of values in the Calumet River start
at less than 10 per 100 ml in the Harbor area and increase
to about 100 to 400 per 100 ml through the Calumet River to
O'Brien Locks. The fecal coliform densities increased to a
level of 65,000 per 100 ml at the sampling station below the
influent of the Calumet Sewage Treatment Works. From this
point on down to CSC 19.87 the fecal coliform densities
fluctuated between 20,000 and 60,000, then declined to a
geometric mean value of 14,000 per 100 ml at CSC 13.11,
U. S. Highway 83. An individually high value of 520,000
per 100 ml was observed at Cicero Avenue, CSC 23.97 on the
Cal-Sag Channel.
Table 20 presents the minimum, maximum and geo-
metric mean values for the fecal streptococcus densities
that were observed in the Cal-Sag Channel and the Little
Calumet River - Calumet River system. Figure 36 is a plot
of the observed values. The waters entering from the
-------
610
V. W. Bacon
Calumet Harbor had a geometric mean fecal streptococcus
density of 7 per 100 ml. Levels then increased within the
Calumet River to between 200 and 300 per 100 ml. Moving
downstream to the Little Calumet River there is a rise in
the vicinity of the Calumet Treatment Works discharge to
a geometric means value of about 1,800 per 100 ml. As the
waters move down through the Cal-Sag Channel from below
station CSC 27.99 the general trend of fecal strepto-
cocci was downward as the waters passed through the Cal-Sag
Channel to CSC 13.11 near the confluence with the Sanitary
and Ship Canal. The fecal streptococcus geometric means
generally decreased from 2,000 per 100 ml at the upper end
to about 30 per 100 ml at the lower end of the Cal-Sag
Channel. The ratio of total coliform to fecal strepto-
coccus densities based upon geometric means was found to be
35 to 1 at HaIsted Street just below the Calumet Treatment
Works and up to 350 to 1 at CSC 13.11, U. S. Highway 83, on
the lower section of the Cal-Sag Channel. A more detailed
discussion of the sampling stations along the Calumet River
and Little Calumet River will be presented with the Calumet
surveillance data.

III. SANITARY AND SHIP CANAL AT LEMONT AND LOCKPORT
Because the analytical program at these stations
was carried out at much greater frequency, a more detailed
review of these data is warranted.
Dissolved oxygen data for both 1965 and 1966 are
presented in lables 41 and 42 and plotted in Figures 61 to
64. The figures show only the monthly mean values, in terms
of percent saturation and in mg/1. There are no signifi-
cant changes between these stations. Both show extremely
low values, with Lockport consistently lower than Lemont.
The critical DO levels occurred between April and October.
Summertime levels at Lemont averaged 1 mg/1 or less between
May and October, and below 5 mg/1 even in the winter. At
Lockport, summertime averages were 1 mg/1 or less between
April and October, and below 4 mg/1 in winter.
The Tables present a more definitive breakdown
of the oxygen data, showing the monthly frequency distri-
bution. The Lemont data consists of four daily samples
taken during the daylight hours, and the Lockport data
represent the readings from a continuous DO monitor.
Although there is some difference in the frequency distri-
butions between 1965 and 1966, it is apparent from these
-------
V. W. Bacon 612
Tables that a DO minimum of 1.0 mg/1 was achieved at
Lemont, only in the five winter months in 1965 and only
in three winter months in 1966. DO values below 1.0 mg/1
occurred as high as 91 percent of the time in July 1965, the
worst month, and 100 percent of the time in 1966. The
Lockport data showed a similar pattern, except that in
1965, September appeared to have the period of lowest
DO with 97 percent of the values below 1 mg/1. In 1966
the DO values were less than 0.5 mg/1 97 percent of the
time.
The monthly average temperature data for these
two stations are presented in Figures 65 and 66. The
Lockport readings are consistently higher than Lemont. The
data also show that 1966 temperatures were usually higher
than 1965 temperatures at both stations by about 2° or
3° C. The month of July exhibited the highest mean tempera-
ture.
COD and BOD monthly average data are shown in
Figures 67 and 68. The COD data measured only in 1966
are consistent with expected patterns, showing slight re-
duction in levels at Lockport over that found at Lemont.
In general, the COD decrease from high values in January
and February to lower levels in August and September. The
BOD data with Lockport showing a BOD of about 7 mg/1
-------
V. W. Bacon 6l3
higher than Lemont indicate a much different condition.
This data, at first glance, would indicate that there is
a very large organic load entering the canal system be-
tween Lemon t and Lock port, when, in fact, no such discharge
is known to occur. The logical explanation, supported by
the COD data, is that the BOD rise Is due to nitrification
occurring at a much faster rate in the Lock port samples
than in Lemont.
If the high BOD were due to an organic load from
waste discharges, the COD would show a similar rise. Also,
because of the large flows, this BOD difference between
the two stations would represent a loading of about 130,000
pounds per day, equivalent to a P.E. of 780,000. Such a
loading is not known to be present in this reach of the
waterway.
The nitrogen data, Figures 69 and 70, show the
total nitrogen values averaging between 7 and 9 mg/1
throughout the year 1966. Approximately 70 percent of the
total nitrogen is in the form of free ammonia. The un-
oxidized nitrogen will result in heavy oxygen demands at
downstream locations due to possible conversion to nitrite
and nitrate by nitrifying bacteria.
The conductivity and total dissolved solids data
(Figures 71 and 72) for these stations follow similar
-------
V. W. Bacon 6l4
patterns for the two years of record, with the higher
dissolved solids values occurring in the colder months.
Extremely high values were observed during May 1965 with
a mean value of 1165. Based upon the 1965 and 1966 data,
the average ratio between dissolved solids and conductivity
was found to be 0.64 at Lemont and 0.73 at Lockport.
Chloride patterns (Figures 73 and 74) are similar
to the conductivity and dissolved solids, as expected. The
higher concentrations of chlorides occurring in the winter
and early spring months must likely be a result of the
heavy salting operations practiced in the Chicago area.
Average chloride levels in 1966 were about 10 mg/1 higher
than 1965 for each month of record.
The suspended solids levels at Lock port (Figures
75 and 76) were consistently below those found at Lemon t,
with minor exceptions* However, the concentrations found
were high at both stations, averaging 30 mg/1 or above
for most of the two years of record. At least 60 percent
of the suspended solids was organic in nature.
Turbidity data (Figure 77) show a comparable
pattern to suspended solids, as expected.
pH values at both stations were well within the
neutral zone. No problems due to highly acid or alkaline
waters were observed. A slightly higher alkalinity is
-------
V. w. Bacon 6l5
evident at Lemont (Figures 78 and 79).
Streamflow measurements for both stations are
presented in Figures 80 and 81. Tables 43 and 44 present
the monthly average Physical and Chemical water quality
data in summary form.
IV. CALUMET AREA SURVEILLANCE PROGRAM
This section presents an evaluation of the present
water quality in the Calumet Area under the jurisdiction
of The Metropolitan Sanitary District of Greater Chicago.
This evaluation is based upon the data collected by the
sampling program instituted in October of 1965. Samples
were collected for chemical and physical analyses on a
once-a-week basis from twelve locations on the various
rivers in the Calumet Area. The identification and location
of sampling stations was presented in Figure 2. In addi-
tion, data was collected during extensive studies in the
summer of 1965 in the Calumet River only. A summary of
this data is also presented for comparison with the Cal-
umet Surveillance Program. The data collected between
October 1965 and October 1966 has been divided into
three seasonal periods which are as follows :
1. Winter period includes December 1965,
-------
V. W. Bacon
January, February and March 1966.
2. Summer period includes June, July, August
and September 1966.
3. The Spring and Fall period includes October,
November 1965 and April, May 1966.
The various chemical and physical analyses have
been evaluated according to minimum, mean and maximum
values for each of the seasonal periods. Similarly, the
bacteriological data has been calculated on the basis
of minimum, maximum and geometric mean values for each
seasonal period.
A. CHEMICAL AND PHYSICAL EXAMINATIONS
The results of the chemical and physical analyses
for each of the individual surveillance stations are sum-
marized in Tables 31 through 32. The minimum, maximum and
mean values are given for the year as well as for each of
the seasonal periods previously mentioned. The analyses
summarized in these tables are temperature, dissolved
oxygen, BOD, COD, organic nitrogen, ammonia nitrogen,
nitrite and nitrate, pH, total alkai'nity, specific
conductance, chloride, sulphate, phenols, hexane solubles,
and total phosphates. In order to compare the changing
-------
617
V. W. Bacon
water quality from station to station, the data has been
plotted for the whole Calumet area river system on a para-
meter basis, and the resulting curves are shown in Figures
37 through 58. The following discussion will cover some
of the individual parameters and some of the more pertinent
observations with regards to them.
Temperature
The general trend of increased temperatures in the
middle portion of the Calumet River is due to the numerous
cooling water discharges in this area. A rise of 6° C.
occurred between mile station 41.64 and mile station 39.8
with summertime temperatures reaching a mean value of 28 C.
and maximum value of 35° C. Downstream of this station,
temperatures tend to decline slightly to mean values of
19° C. in summer, 13 C. in spring-fall and 6° C. in
winter, at CSC 27.99 Differences as high as 19 C. occurred
between the summer and winter average temperatures.
Dissolved Oxygen
The dissolved oxygen levels showed seasonal
differences with lower levels of DO experienced during the
-------
618
V. W. Bacon
warmer summer months, as shown in Figure 38. The lower
DO values are related to decreased solubility and increased
biological activity during the warmer months. All the
stations yielded some level of dissolved oxygen. However,
several of the stations had observed values of less than
1 mg/1 of dissolved oxygen, especially during the summer
months. At Station GCR 34.83 on the Grand Calumet River,
ten samples out of 46 had values of less than 1 mg/1. Five
out of 49 samples taken at LCR 29.02, HaIs ted Street, on the
Little Calumet River, were below 1 mg/1 DO.
The pH values for the samples collected in this
area varied between 6.8 and 8.3 with only a slight decrease
occurring in pH from the first station in from lake Michi-
gan on down to the station on the Cal-Sag Channel at
Ashland Avenue.
BOD
In the Calumet River, the mean BOD ranged between
less than 1 mg/1 to 4 mg/1. An occasional value of 15 mg/1
was observed at several of the stations on the Calumet
-------
619
V. W. Bacon
River. Station GCR 34.83, Torrence Avenue, on the Grand
Calumet River, showed seasonal fluctuations in the BOD
values with the winter BOD's ranging between 3 mg/1 and
7 mg/1, with a mean of 6 mg/1. The spring and fall BOD's
ranged between 4 and 36 mg/1, with a mean of 13 mg/1.
CSC 27.99, Ashland Avenue on the Cal-Sag Channel, which is
below the confluence of the Cal-Sag Channel and the Little
Calumet River and also below the Calumet Treatment Works,
had a yearly average BOD of 6 mg/1.
COD
The COD results for the various seasonal periods
are shown in Figure 40. The summer values tend to be
on the low side while the spring and fall values tend to
be higher on the average. Based on the yearly average, the
COD increased from about 12 mg/1 at CR 41.64, Swing Ave-
nue, to about 22 mg/1 at 130th Street on the Calumet River,
with the addition of various industrial wastes. The sharp-
est increase occurred after the Calumet Treatment Works,
with the COD levels going up to a yearly average of 45
mg/1. At LCR 29.18 on the Little Calumet River and GCR
34.83, Torrence Avenue on the Grand Calumet River, high
COD values were found in keeping with the high BOD values.
-------
V. W. Bacon 620
ODD values range on a yearly average of 48 mg/1 at LCR
29.18 and 52 mg/1 at GCR 34.83
Nitrogen
The observed seasonal averages for organic nitro-
gen, ammonia nitrogen and nitrite-nitrate nitrogen are
shown in Figures 42, 43 and 44, respectively. The lowest
values for both organic nitrogen and ammonia were observed
during the summer season. Conversely, in the summer sea-
son, higher nitrite nitrate values were observed as com-
pared to the rest of the year; thus indicating active nitri-
fication occurring in this particular region of the water-
ways system. For example, at Station CR 36.01, 130th
Street on the Calumet River, the total organic plus ammonia
nitrogen decreased by about 2.5 mg/1 from the winter to
the summer period; whereas, the nitrite-nitrate nitrogen
increased by 2.7 mg/1 in the same period on a seasonal
average basis. The individual values of organic nitrogen
fluctuated widely throughout the Calumet River and the
Little Calumet River System. The average organic nitrogen
increased from 0.4 mg/1 at CR 41.64 downstream to a value
of 0.8 mg/1 at CSC 27.99 at the upper end of the Cal-Sag
Channel. Ammonia values at CR 41.64, Ewing Avenue, the
-------
V. W. Bacon
Calumet River Station closest to Lake Michigan, showed a
yearly range of 0.1 to a maximum 2.8 mg/1 with a yearly
mean value of 0.5 mg/1. Then ammonia rose to about 1.8
mg/1 at 106th Street and remained between 1.4 and 1.8
mg/1 until LCR 29.02, HaIs ted Street on the Little Calumet
River, which is the first station downstream of the Calumet
Treatment Works. At this location, the yearly average of
7.4 mg/1 represents an increase in ammonia concentration of
about 5 mg/1 over the upstream station. Nitrite-nitrate
concentration from the spring, fall and winter season in
the Calumet River lake-ward of the O'Brien Locks were on
the average of 0.6 to 1 mg/1. From O'Brien Locks down to
CSC 27.99, Ashland Avenue, on the Cal-Sag Channel, the
nitrite-nitrate levels remained fairly constant at about
1.2 to 1.3 mg/1. During the summer, as previously noted,
the nitrite-nitrate levels increased rather markedly to a
summer mean value of 1.6 mg/1 at Ewing Avenue on the
Calumet River and 4.1 mg/1 at Ashland Avenue on the Cal-Sag
Channel.
At Station OCR 34.83, Torrence Avenue, on the Grand
Calumet River, the organic nitrogen concentration averaged
2.8 mg/1 and the ammonia nitrogen averaged 4.4 mg/1.
The Little Calumet River at Station BLCR 29.18,
Ashland Avenue, which is between the confluence of the
-------
V. W. Bacon
Cal-Sag Channel and the Illinois-Indiana State Line,
had an average organic nitrogen concentration of 2.5 mg/l
and ammonia concentration of 4.9 mg/l.
Specific Conductance
Figure 45 presents the conductivity results for the
various seasons as designated. The specific conductance
values did not exhibit any appreciable seasonal fluctuations.
The yearly mean value increased from Lake Michigan as the
water moved inland towards O'Brien Locks, due to the discharge
of various industrial outfalls. At Station CR 41.64, the year-
ly mean was 280 micromhos/cm. This value increased to 430
micromhos/cm at Station CR 36.01, just above O'Brien Locks.
Samples taken at GCR 34.83, Torrenee Avenue, on the Grand
Calumet River, over the yearly period range between 460 mini-
mum and 950 maximum, with a yearly average of 710 micromhos/cm.
The high conductivity values at this station are in keeping
with the high values also found for other parameters at
this station. The conductivity level increased sharply
below the Calumet Treatment Works at Station LCR 29.02.
For the winter, summer, and spring-fall periods, the averages
were 720, 690, and 580 micromhos/cm, respectively.
-------
623
V. W. Bacon
The two stations on the Branch of the Little
Calumet River, which are both above the junction with the
Cal-Sag Channel but before the Indiana State Line, showed
extremely high conductivity values. At BLCR 33.53,
Indiana Avenue, which is closest to the Illinois-Indiana
State Line, the 21 samples taken showed a range from 600
to 2100 jjhos/cm. The winter and summer seasonal averages
were 1,000 and 1,580, respectively.
Chlorides, Sulfates
Seasonal mean values found for chlorides and
sulfates are shown in Figures 46 and 47. These two con-
stituents follow the same general pattern as the specific
conductivity measurements. At CR 41.64, Ewing Avenue,
there was no seasonal difference in the chloride values.
The yearly mean was 19 mg/1. Chlorides levels increased as
the water flows inland toward O'Brien Locks. At 130th
Street, values of 58, 48 and 55 were found for the winter,
summer, spring-fall beans. The chloride levels stay
fairly constant until just below the Calumet Sewage Treat-
ment Works where as LCR 29.02, Halsted Street, the con-
centrations nearly double. At this location, the winter
period had a mean value o± 108 mg/1, the summer period had
-------
62JJL
V. W. Bacon
a mean value of 72 mg/1 and the spring-fall period showed
a mean value of 78 mg/1. It should also be noted that the
chloride levels were much higher during the winter period
than the other two periods at this station.
The sulfate levels increase from a yearly mean
value of 26 mg/1 near the mouth of the Calumet River (CR
41.64) up to a mean value of 81 mg/1 at CR 36,01, 130th
Street, which is still lakeward of O'Brien Locks. The levels
stay fairly constant down to the Calumet Treatment Works,
where, similar to the chloride values, the sulfate values
double. At Halsted Street, the mean values for the winter,
summer, spring-fall periods were 190, 157 and 172 mg/1,
respectively.
Rather high levels of chlorides and sulfates were
found at OCR 34.83, Torrence Avenue, on the Grand Calumet
River. The two stations on the Branch of the Little Calumet
River showed extremely high chloride and sulfate values, simi-
lar to the extremely high conductivity values. At these two
stations, the highest values occur during the summer months
rather than the winter or spring-fall months, as was noted at
several of the other sampling stations. The winter mean chloride
value was 147 mg/1. The winter mean sulfate value was 193 mg/1.
The summer mean value for chlorides was 256 mg/1, for sul-
fates, 370 mg/1. The spring and fall mean values were, for
chlorides, 116 mg/1, and for sulfates, 196 mg/1.
-------
V. W. Bacon
Phenols
The average values for phenols, as shown in
Figure 50, were greater during the winter months at the
majority of the sampling stations. With colder tempera-
tures and decreased biological activity, the phenols are
not as readily decomposed, and thus tend to be more per-
sistent. This assumes that the source of phenols to the
waterways remains constant throughout the year. During
the winter period, the fluctuation in the measured phenols
levels was quite marked. The highest levels in the Calu-
met River occurred at Station CR 39.81, 106th Street. The
mean winter value was found to be 25 micrograms / liter.
The summer and spring-fall mean values were 4 micrograms /
liter at this location. The level of phenolics at the
upper end of the Gal-Sag Channel, CSC 27.99, showed an
average of 21 micrograms / liter.
Hexane Solubles
Hexane solubles are a measure of the oil content
of the water sample. The difficulty in sampling for oils
is reflected in the wide scatter within the hexane
soluble results. The highest values were observed during
-------
V. W. Bacon 626
the spring-fall period, with a mean ranging between 70 mg/]
and 105 mg/1. The mean during the summer period ranged
between 4 and 16 mg/1 at the various sampling locations.
The locations which showed the highest levels were at
CR 36.01, 130th Street, on the Calumet River and at
BLCR 33.53, Indiana Avenue, on the Branch of the Little
Calumet River below the Indiana-Illinois State Line. The
mean values during the spring-fall period were 105 mg/1
at 130th Street and 131 mg/1 at Indiana Avenue.
Total Phosphates
The yearly mean total phosphate values in the
Calumet River ranged from 0.11 mg/1 at CR 41.64, Ewing
Avenue, to 0.30 mg/1 at CR 36.01, 130th Street, as shown
in Figure 28. The Grand Calumet River at GLCR 34.83.
had mean values of 4.96 mg/1 in the winter, 6.48 mg/1 in
the summer, and 4.15 mg/1 in the spring and fall. Unus-
ually high levels of total phosphates were found in the
Branch of the Little Calumet River at both sampling sta-
i \
tions. The Indiana Avenue, mile 33.53, showed mean values
for the summer, 27.18 mg/1; for the spring-fall, 10.22
mg/1; for the winter, 9.90 mg/1. Station BLCR 29.18 at
Ashland Avenue on the Little Calumet River showed the
-------
62?
V. W. Bacon
highest phosphate levels occurring in the summer, with
a mean of 25,40 mg/1 followed by the spring-fall with a
mean of 9.89 mg/1 and then the winter of 5.41 mg/1.
Although the flow is low in this part of the Little GUu-
met River, the concentrations are sufficiently high to
result in an increase in total phosphates in the Cal-Sag
Channel, below the confluence. Above the confluence at
LCR 29.02, Ha Isted Street, the yearly average value was
1.67 mg/1. Below the junction of the Little Calumet
River and Cal-Sag Channel at CSC 27.99, Ashland Avenue, the
yearly average value was 2.79 mg/1.
Mineral Constituents
The concentrations of calcium, magnesium, potas-
sium, and sodium found at each station during January
through September 1966 are presented in Table 1. These
results are presented as the minimum, maximum, and
median of the observed values and are also plotted in
Figures 52 to 55.
The concentrations of calcium increased, as the
waters proceed inland, from a median value of 43 mg/1 in
the Calumet River at CR 41.64, Ewing, to a median value
of 83 mg/1 at CSC 27.99, Ashland, on the Cal-Sag Channel.
-------
V. W. Bacon
Exceedingly high concentrations of calcium were found on
the Grand Calumet River ranging between 39 and 140 mg/1
at station GCR 34.83. Similarly, the stations on the non-
navigable reach of the Little Calumet River between the
Illinois-Indiana State Line had high median calcium con-
centrations of 112 and 120 mg/1.
The magnesium levels also increased from a
median of 12 mg/1 near the mouth of the Calumet River (CR
41.64) to a median value of 26 mg/1 at the upper end of
the Cal-Sag Channel (CSC 27.99).
From station CR 41.64 on the Calumet River to
station CSC 27.99 on the Cal-Sag Channel, the median levels
of potassium increased from 2.6 mg/1 to 8.5 mg/1.
Sodium concentrations gradually increased from a
low median value of 6.8 mg/1 near the mouth of the Calumet
River to a median value of 7.5 mg/1 at LCR 31.34 on the
Little Calumet River just above the Calumet Treatment Works.
At the next station (LCR 29.02) below the Calumet Treatment
Works, the sodium concentrations increased to 63 mg/1. The
samples taken at the two stations on the non-navigable
reach of the Little Calumet River had extremely high sodium
concentrations ranging between 30 and 226 mg/1 with a median
value of 112 mg/1.
-------
V. W. Bacon
Heavy Metals
The various heavy metals were found in general to
be very low* Table 35 presents the frequency of occurrence
above detectable limits and the ranges of concentrations
found at the various sampling stations.
At all locations, zinc was found in measurable
amounts, varying from a range of 0.03 - 0.04 mg/1 at
CR 41.64 on the Calumet River to the highest range of 0.01 -
2.00 mg/1 at station LCR 29.02 on the Little Calumet River.
At the sampling stations on the Calumet River,
concentrations of manganese varied from below the detection
limit of 0.02 mg/1 to a high of 1.33 mg/1. At station
LCR 29.02, Hals ted Street, on the Little Calumet River,
the manganese levels varied from 0.08 to 14.13 mg/1.
Copper was found in measurable amounts in only
two out of 148 samples from the Calumet River. All samples
from the Grand Calumet River were found to be below
detectable limit of 0.03 mg/1.
B. CALUMBT AREA CHEMICAL QUALITY COMPARISONS (1965 - 1966)
A survey of water quality on the Calumet River was
made during the period extending from June 2l to August 4,

1966. The result of the chemical analyses is presented
in Table 33. A comparison of the results and levels of
constituents found during the summer of 1965 period with
the summer of 1966 surveillance data is made in the follow-
ing section. Table 33 presents the minimum, maximum and mean
values of the 13 samples which were taken during the 1965
summer period. The area under discussion extends from the
Calumet Harbor inland to the Thomas J. O'Brien Locks.
Station; CR 41.64 Swing Avenue - Calumet River
The average summer period temperatures were
within the same ranges for both periods with a mean value
of 22° C. The mean DO level of the 1966 samples was
5.4 mg/1 ranging between 3.8 and 7.0 mg/1. The 13 samples
collected during July - August 1965 had a mean DO of 6.3.
The samples varied between 5.3 and 7.4 mg/1. The COD
values showed a noticeable reduction from the 1965 sampling
period. The average COD value dropped from 28 mg/1 in
the 1965 period to a mean of 10 mg/1 for the 16 samples in
1966. Both organic nitrogen and ammonia showed comparable
levels during both study periods. Organic nitrogen found
was 0.6 mg/1 in 1965 and 0.4 mg/1 in 1966. The ammonia
values averaged 0.2 mg/1 in both cases. A sharp increase
-------
631
V. W. Bacon
in nitrite-nit rate occurred during the summer of 1966 period
as compared to the July 1965 period, increasing from 0.3 to
1.6 mg/1 at this station. The concentration of phenol was
within the same range during both periods and varied from
less than 1 fag/1 to 1O ug/1.
Station CR 39.81 - lO'Sth Street - Calumet River
The dissolved oxygen averages remained the same"
between the two sampling periods. However, the range of
the dissolved oxygen concentration was slightly greater
in 1965 period varying between 5.3 to 7.4 mg/1 for the 13
samples. In 1966 tine range of dissolved oxygen values for
16 samples was 3.5 to 6.2 mg/1. This could possibly be due
to the comparison of four months in 1966 to only one month
in 1965. A sharp decrease in COD values is noticed between
the two periods from 42 mg/1 in 1965 to 13 mg/1 in 1966.
Chloride concentrations showed a slight increase from 20 to
39 mg/1. The org;anic nitrogen and nitrite-nitrate concentra-
tions have both increased over the 1965 sampling period. The
average value for organic nitrogen increased from 0.8 mg/1 to
1.6 mg/1, in 1966. Nitrite-nitrate levels showed a substantial
rise from 0.4 m|5/l in the 1965 period to 2.6 mg/1 in the
1966 period. T!He ammonia values of the 13 samples in July 1965
-------
V. W. Bacon
and the 16 samples in the summer of 1966, were substantially
the same. Similarly, the phenol values ranged about the
same level for both sampling periods.
Station CR 37.07 - Torrence Avenue - Calumet River
At this station the mean temperatures were slightly
lower in the 1966 period as compared to the 1965 period.
This was mainly due to the inclusion of September data as
compared to only June to July data for 1965. The 1965
sampling period temperature ranged from 27 to 29° C. with a
mean value of 28° C. During the summer period of 1966 the
temperature ranged between 16 to 25° C., with a mean value of
22° C. The dissolved oxygen levels were found to be higher
during the 1966 period, increasing from a mean value of
1.9 mg/1 in the 1965 period to 2.4 mg/1 in the 1966 period.
The level of the chlorides and sulfates also were higher at
this station during the 1966 period. This increase is re-
flected in an increase in specific conductivity from an
average of 374 micromhos/cm in 1965 to an average of 410
micromhos/cm in summer 1966. Both the organic nitrogen and
ammonia nitrogen levels were less in the 1966 period as com-
pared to 1965 period. For the 13 samples taken in 1965, the
organic nitrogen ranged from 0.6 to 1.6 mg/1, with an average
-------
633
V. W. Bacon
of 1.0 mg/1. In the summer 1966 the organic nitrogen
ranged from less than 1 mg/1 to 4.2 with an average of 2.2
mg/1. Similarly, the ammonia nitrogen values averages 2.1
mg/1 in 1965 while the average for the 16 samples of 1966
was 1.5 mg/1. The nitrite-nitrate value showed a corres-
ponding increase between the two sampling periods. The mean
values increasing from 0.5 mg/1 to 2.9 mg/1. The 13 phenol
samples in 1965 ranged from 0 to 22.3 Pg/l with an average of
5.9 Vg/1. In 1966 the mean concentration was 3 ug/1 with
a maximum of 11 Vg/1 and a minimum value of less than 1 ug/1.
Decreases in phenols are possibly due to the increased tem-
peratures during the 1966 period, resulting in a greater bio-
degradation of the phenols within the waterway system.
Station CR 36.01 - 130th Street - Calumet River
A slightly lower temperature was observed in the
1966 period, with the average temperature 2° C. lower than
in the 1965 period. There was no appreciable difference
in the average DO contents found for the two periods. The
average ammonia concentrations were 2.1 mg/1 for the 13
samples in July 1965 as compared to 1.5 mg/1 for the 16
samples in the summer of 1966. The 16 samples in the summer
1966 period showed higher sulfate concentrations, with a
-------
V. W. Bacon
mean of 82 mg/1, as compared to the July 1965 samples with
a mean of 51 mg/1.
C. BACTERIOLOGICAL EXAMINATIONS - CALUMET AREA
The twelve river stations were sampled weekly for
total coliform and fecal streptococcus since October 1965.
However, for the purposes of evaluation only the data up
to October 1966 is presented in this report. Fecal coliform
densities were determined on samples collected from June 1966
through October 1966. Tables 36, 37, 38 present the maximum,
minimum and geometric mean values of total coliform, fecal
coliform, and fecal streptococcus observations respectively.
The data has been separated into three main seasonal
periods as previously discussed. In order to follow the
trends which occurred in relation to the various sampling
stations, the geometric mean counts of each of the bacterio-
logical determinations were plotted on a seasonal basis.
The plot of the total coliform densities are shown in
Figure 9 and the fecal streptococcus densities are plotted
in Figure 60. In addition to the data collected from the
weekly surveillance program, a number of bacteriological
samples were collected during an intensive survey conducted
in the Calumet River from lake Michigan to O'Brien Locks
-------
635
V. W. Bacon
during the period extending from June 21 through August 4,
1965. These latter samples were analyzed for total coli-
form and fecal streptococcus densities, and the maximum,
minimum, and mean values per 100 ml observed for these two
parameters are given in Table 39. The following section
is a discussion of the data collected from each of the
sampling stations.
Station CR 41.64. Swing Avenue. Calumet River
The total coliform counts made on the samples
collected at this station varied from a minimum of 40 to
a maximum of 44,000 per 100 ml with a geometric mean value
of 633 over the total yearly period* The higher coliform
densities occurred during the summer and spring-fall period.
In contrast, the winter period having a geometric mean of
only 162 per 100 ml as compared to 1,550 per 100 ml during
the summer period. Two out of the 16 samples had extremely
high values, one of 44,000 per 100 ml and the second of
34,000 per 100 ml.
The fecal coliform counts during the summer
period varied from 28 per 100 ml to 44,000 per 100 ml, with
a corresponding geometric mean of 371. The fecal strepto-
coccus counts varied from 8 to 2200 per 100 ml with a
-------
636
V. W. Bacon
geometric mean of 116 with the summer and spring-fall
values being higher than the winter values.
Comparison of the total col if or m counts during
June-August 1965 period with those in the summer of 1966 shows
higher densities during the 1966 summer period. The 13
samples collected in 1965 showed a coliform count minimum
of 70 and maximum of 1400 per 100 ml with a geometric
mean of 363 per 100 ml as compared to a geometric mean of
1550 per 100 ml for the summer of 1966 • Hie fecal strepto-
coccus densities varied between less than 10 per 100 ml and
250 per 100 ml, with a geometric mean of 88 per 100 ml.
Whereas, the summer 1966 data showed a geometric mean of
155 per 100 ml. The Ewing Avenue station is situated
between the mouth of the Calumet Harbor and the entrance to
the Howard Slip into which the 95th Street Pumping Station
discharges during periods of storm. A review of the
pumping records showed that the frequency of occurrence of
discharge to the Howard Slip was greater during the 1966
summer period than it was during the 1965 survey period. The
two days upon which high counts were observed followed
periods of storm discharge to Howard Slip.

V. W. Bacon
Station CR 39.18. 106th Street. Calumet River
This station is also located on the lake ward side
of the O'Brien Locks approximately 2.6 miles inland from the
mouth of the Calumet River and downstream of Howard Slip
the summer period showed the highest densities with total
coliform counts ranging from 410 to 111,000 per 100 ml with
a geometric mean of 1,390 per 100 ml. The overall geometric
mean value of total coliforms for the yearly period was 143.
The geometric mean values in the spring-fall period were
remarkably lower at this station than at the upstream
station, Ewing Avenue. This is primarily due to the absence
of the individual high maximum coliform counts that were
observed at Ewing Avenue.
The fecal coliform densities for the 16 samples
ranged from a minimum of 70 to a maximum of 1,900 per 100 ml
with a geometric mean of 267 per 100 ml. Fecal streptococcus
values for the year ranged from 5 to 3,500 per 100 ml with a
geometric mean of 95 per 100 ml. The summer months yielded
a geometric mean of 143 per 100 ml.
Similarly to Station CR 41.64 the coliform densities
observed were slightly higher during the summer 1966 sampling
period as compared to the 1965 sampling period. In 1965 the
13 samples collected showed a range for total coliform of
-------
V. W. Bacon 638
200 to 1,000 per 100 ml with a geometric mean of 418.
CR 37.07 - Torrence Avenue, Calumet River
A slight increase occurred in the bacteriological
densities observed at this point compared to the upstream
stations. The total coliform count ranged from 120 up to
31,000 with a geometric mean of 1450. Die 16 samples col-
lected during the summer period of 1966 yielded fecal coli-
form counts from a minimum of 70 to a maximum of 3,000 per
100 ml, with a geometric mean of 450 per 100 ml. The fecal
streptococcus values were also higher than the upstream
stations varying between 10 and 16,000 with a geometric mean
of 320. The 16 samples taken during the summer 1966
period showed higher average total coliform and fecal
streptococcus as compared to the 13 samples in July 1965.
Station 36.01 - 130th Street - Calumet River
This station is located about a half mile lakeside
of the O'Brien Locks. The flow at this point consists of
the lake water after receiving industrial waste discharges
from the various steel mills and chemical plants along the
Calumet River, as well as input flow at varying times from
-------
V. W. Bacon
Lake Calumet. The total coliform values ranged from 10 to
77,000 with a geometric mean of 710. It should be noted
that a single high value of 77,000 occurred during the
summer period and that the second highest value was only
3200 per 100 ml of the 29 samples collected. The fecal
coliform value for the summer period ranged from 20 to 1300
with a geometric mean of 216, the second highest value
being only 480 per 100 ml. The fecal streptococcus
values ranged from less than 5 to 1800 with a geometric
mean of 81 per 100 ml. These values are slightly higher
than the 13 samples which were collected in the summer of
1965. During this period the total coliform count varied
between 120 and 70 with a geometric mean of 73. The fecal
streptococcus count ranged from less than 10 to 800 with
a geometric mean of 46; whereas, the summer data in 1966
shows a total coliform count minimum of 200 and a maximum
of 76,000 to 77,000 with a geometric mean of 1200.
Station BR 34.83 - Grand Calumet at Torrence Avenue
This station is located Just upstream approximately
a tenth of a mile from the confluence of the Grand Calumet
and Little Calumet Rivers, southeast of the O'Brien Locks
Controlling Works. The total of the 46 samples collected
-------
640
V. W. Bacon
over the yearly period at this station yielded a minimum
total coliform value of 2000 and a maximum value of 9,000,000
per 100 ml. The fecal coliform values for this group are
also high ranging from 500 upwards to 1.3 million with a
geometric mean of 29,900. The fecal streptococcus values had
a geometric mean of 1,270 and ranged from less than 5 up to
119,000. These levels show the gross arterial pollution which
is coming down the Grand Calumet River.
Station BR 31.34 - Indiana Avenue - Little Calumet River
Since the Little Calumet River at this point flows
southwest toward the Cal-Sag Channel, the sampling station
is located upstream and northeast of the Calumet Treatment
Works. The total coliform counts ranged between 900 and
1.3 million per 100 ml with a geometric mean of 16,700 per
100 ml. The maximum observed value was during the spring-
fall months. The second highest value only being 160,000
per 100 ml with 50 percent of the values being less than
29,000 per 100 ml. The fecal coliform values ranged bet-ween
150 and 20,000 per 100 ml with a geometric mean of 2200 per
100 ml. These levels are slightly increased over the upstream
station on the Calumet River.
-------
641
V. W. Bacon
Station LCR 29.02 - Ha Isted Street, Little Calumet River
This station is located just downstream of the
Calumet Treatment Works discharge. Samples collected at
this point had a total coliform count ranging from a
minimum of 10,000 on upwards to a maximum of 11,000,000 per
100 ml and a geometric mean of 170,000 per 100 ml. The
second highest maximum value observed was 2.2 million per
100 ml. The highest coliform densities were during the
summer and spring-fall months. The geometric mean fecal
coliform density was 82,500 per 100 ml. The fecal strepto-
cocci counts ranged from 100 up to 110,000 per 100 ml with
a geometric mean of 4,730 per 100 ml. The bacterial
quality of the water at this point reflects the unchlor-
inated effluent coming from the Calumet Treatment Plant.
Station CSC 27.99 - Ashland Avenue. Cal-Sag Channel
This station Is located downstream on the Cal-Sag
Channel below the confluence of the Little Calumet River.
The 49 samples collected over the yearly period yielded
total coliform counts ranging from 26,000 to 3.1 million
per 100 ml, with a geometric mean of 147,000. The maximum
of 3.1 million per 100 ml coincides with the high count
-------
642
V. W. Bacon
at station LCR 29.02 of 11 million per 100 ml. Ninety-six
percent of the values found were less than 2.1 million
per 100 ml. The fecal coliform densities range from 10,000
to 900,000 per 100 ml, with a geometric mean of 67,100 per
100 ml. The fecal streptococci in the 48 samples taken range
from less than 100 up to 110,000 with a geometric mean of
3,990 par 100 ml.
Station 29,18 - Ashland Avenue - Little Calumet River
Ashland Avenue crosses a non-navigable section of
the Little Calumet River upstream of the confluence with the
Gal-Sag Channel. This station should not be confused with
those stations on the main stem or navigation channel of
the Little Calumet River. Total coliform counts varied from
5,100 up to 900,000 per 100 ml, with the geometric mean of
about 56,000 per 100 ml. The highest values'were observed
during the summer periods and range from 13,000 to 900,000
per 100 ml. The fecal coliform values for the 16 samples
during the summer range from 2300 to 90,000 per 100 ml and
a geometric mean of 10,300 per 100 ml. Minimum fecal strepto-
cocci values were less than 100 with a maximum of 110,000
per 100 ml. The fecal streptococci geometric mean values
at this station were 1,330 per 100 ml. Ninety-eight percent
-------
643
V. W. Bacon
of the values in this location had fecal streptococci
densities less than 28,000 per 100 ml. The range of values
for the total coliform, fecal streptococci, and fecal coli-
form were comparable to those found at the Indiana Avenue
GCLR 33.53 station, 4.3 miles upstream from this point.
Although the minimum and maximum values are slightly higher
at this point as compared to the GCLR 33.53 location the geo-
metric mean value was slightly lower.
Station BLCR 33.53, Indiana Avenue. Little Calumet River
Total coliform values range from 4700 up to 660,000
per 100 ml with a geometric mean of 22,300 per 100 ml. The
fecal coliform geometric mean value was 11,800 per 100 ml
with a minimum of 700 per 100 ml and the maximum of 90,000
per 100 ml during the summer months. Fecal streptococci
values ranged from 50 to 90,000 per 100 ml with a geometric
mean of 1600 per 100 ml. The summer period showed the lowest
values with an extremely low geometric mean of only 560 at
this station.
Station Wolf Lake at Spillway
This sampling station is located at the outlet from
-------
V. W. Bacon
Wolf Lake at about 126th Street Just below the spillway.
In general the bacteriological analyses show very low levels in
most of the samples. Total coliform counts ranged between 5
and 600 per 100 ml with a geometric mean of 20 per 100 ml.
The 16 samples taken during the summer months for fecal
coliform gave a range of less than 5 to 209 per 100 ml with
a geometric mean of 77 per 100 ml. The fecal streptococci
values range from 2 to 590 per 100 ml with a geometric
mean of 11 per 100 ml.
Station Carondolet Road - on Wolf lake Ditch
This station is about 3 miles downstream from the
outlet of Wolf Lake. The total coliform count value varied
from 5 to 24,000 per 100 ml with a geometric mean of 199
per 100 ml. However, the maximum of 24,000 per 100 ml
found during the summer months represents a single occurrence.
The second highest value which was observed was 5,100 per
100 ml. The fecal coliform results varied between 30 and
1,000 per 100 ml with a geometric mean of 195 per 100 ml.
The fecal streptococci varied from less than 5 to 380 per
100 ml, with a geometric mean of 82 per 100 ml. A slight
increase in counts is evident when compared to the Wolf
Lake outlet. This may partially be due to surface runoff

entering this drainage ditch.
V. DBS PLAINES RIVER WATER QUALITY AT LEMONT ROAD
Water quality in the Des Plaines River, above its
junction with the Sanitary & Ship Canal, was determined
at only one location, the bridge at Lemont. The data pre-
sented for both 1965 and 1966 represent samples collected
four times daily during daylight hours. Some of the data,
temperatures, DO, and pH are from individual determinations
on each sample. Most of the data represents a daily composite
of these samples. Ibble 4G presents a composite summary of
the data collected for the Des Plaines River at Lemont.
In contrast with the Sanitary & Ship Canal, the
water quality data for the Des Plaines River at Lemont
should be strongly influenced by the large variations in flow,
Figure 82, representing the monthly average hydrograph
for this location for the two-year period indicated, shows
flow extremes of 40 to 2,000 CFS, a fifty fold difference.
However, a scan of the various parameters measured at the
Lemont station shows little apparent correlation.
temperature readings (Figure 83) show the typical
o
seasonal extremes, averaging as high as 28 C. in July of
1965 and at or near zero0 C. in January and lebruary of 1966.
-------
646
V. W. Bacon
pH and alkalinity levels are somewhat higher than
those found in the Canal but are in the expected range
for natural streams of this area. (See Figure 84). Ihe
monthly mean pH values ranged from 7.6 to 8.6. Ihe alka-
linity levels showed great fluctuations, with the monthly
means varying between 160 and 292 mg/1 as CaCO3.
The dissolved solids, conductivity and chloride
data presented in Figures 85 and 86 show that these para-
meters are interrelated. The dissolved solids are consistent'
ly above the level of about 900 mg/1 in the summer of 1966.
Turbidity and suspended solids data, Figures 87
and 88 show high values during the summer low flow periods.
Suspended solids reached a high monthly mean value as
high as 145 mg/1 during summer months with about 60 percent
being organic solids. The cause of this high turbidity is
not clear from these data; however, other parameters suggest
that the cause of these high turbidities is heavy summer time
blooms of algae. The BOD and COD data in Figure 89 tend
to support this observation.
The BOD and COD averages are consistently above
4 and 30 mg/1 respectively, indicating that these waters
are carrying a significant organic load. During the summer
and early fall months of 1965, the levels increased to a
BOD of about 10 mg/1 and a COD of 50 mg/1. The large
-------
64?
V. W. Bacon
differences between the COO and BOD further indicate that
the organic matter is partially stabilized suggesting that
the BOD effect is due to die off of aquatic generated
algae rather than unstable organic matter from sewages.
Dissolved oxygen levels are presented as averages
in Figures 90 and 91 and a frequency distribution form in
Table 45. The data representing monthly averages showed
no levels below 4 mg/1 and the frequency distribution data
showed only occasional observations below 3.0 mg/1. However,
since all these data represent daylight samplings, the diurnal
effect is unknown. High DO variations which are possible in
streams supporting heavy algae growths can easily result in
DO levels near zero during the nighttime hours. Levels of
DO saturation occurred during the early spring and fall
months as a result of photosynthesis.
The nitrogen levels shown in Figure 92 indicate
a considerable degree.

O'Brien Lock and Dam Operation
The Waterways Control Section of the Sanitary
District controls the hydraulic operation of the O'Brien
Lock and Dam to cause a continuous flow of water In the
Calumet River away from Lake Michigan. This Is done by
opening the sluice gates at the Look to predetermined set-
tings depending upon the water levels above and below the
Lock. Telemetering of the water levels to the Waterway
Control Center In our downtown office allov/s for continuous
monitoring of the water levels and making changes to effect
a constant flow.
The year 1966 Is a prime example of this operation.
The monthly flows at the Lock are as follows:
J - 150 cfs J - 270 cfs
P - 170 " A - 3^0 "
M - 470 " S - 380 "
A - 260 " 0 - 370 "
M - 190 " N - 570 "
J - 240 " D - 610 "
average - 340 cfs
During 1966, extensive by-passing to the Calumet
River at Howard Slip was done by the 95th Street Pumping
-------
810
V. W. Baoon
Station. In the month of Maroh a blockage in the discharge
sewer at the pumping station was detected and sewage was
by-passed a considerable part of the time. Increased by-
passing occurred throughout the year due to the blockage
until the blockage was removed In December. The flows by-
passed are as follows:
J - 0 cfs J - 5.7 cfs*
F - 0 cfs A - 0.2 "
M - 17.0 " S - 0
A - 1.2 " 0 - 1.4 "
M - 5.7 " N -22.1 "

INTERLAKE STEEL CORPORATION - CHICAGO PLANT
Preliminary engineering plans have been submitted to The
Metropolitan Sanitary District during December 1966. These
plans depict the following waste treatment facilities used
to abate water pollution:
1. Blast Furnace Plant
Modification of existing thickener with
floculation, cyanide destruction and re-circulating
facilities.
2. Coke Plant
-------
V. W. Bacon
Installation of a piping system which will
discharge phenolic, cyanide and ammonia wastes to
the Sanitary Sewer.
Final engineering scheduled for approval before
October 31, 1967, with all systems installed and
operational before June 30, 1968.
REPUBLIC STEEL CORPORATION
The following has been accomplished:
1. 14" Mill
The new IV Bar Mill is nearing completion,
and it is anticipated that this mill will be in
operation during the third quarter of this year.
More than $500,000 is being spent on water treating
facilities in connection with this installation.
The 14" Mill's pollution abatement facilities
/
consist of two scale pits with automatic and con-
tinuous oil and scale removal facilities. Effluent
from the pits is recycled for scale flushing in the
mill. A complete water treatment plant is being
constructed to treat a portion of the scale pit
water, to a higher quality for certain uses on the
mill.
-------
V. W. Baoon 818
All cooling for the furnaces, air compressors
and related facilities Is handled through a separate
eystem, passing through cooling towers, and con-
tinuously reused. Blow down from this system will
be to the mill scale system.
Although the water demand on this mill will
be In excess of 8,000 gallons per minute, the
discharge will be limited to 300-400 gallons per
minute of coagulated and clarified effluent.
2. Waste Pickle Liquor
Wheelabrators have been installed in various
locations to remove the scale from the bars by
grit blasting as a replacement for the acid
pickling operations. Units installed In the 11,
12, and 32" mills have replaced five large pickle
tanks reducing the acid usage.
This use of Wheelabrators has reduced the use
of sulphuric acid for pickling by an estimated
65 percent of the total formerly used.
In addition, all of the spent pickle liquor
from the Continuous Coil Anneal and Wire Mill which
was formerly discharged to the river is now being
hauled from the plant by an outside contractor,
and averages in excess of 500,000 gallons per month.
-------
819
V. W. Bacon
3. Blast Furnace Dust
Solids from the blast furnace gases are removed
through a series of gas cleaning devices. Waste
water from the gas washer and preclpitator are
transferred to a thickener for treatment prior
to being discharged to the river.
The thickener is 105 feet in diameter and
has a retention time in excess of four hours.
Mechanical scrapper and a slurry pumping system
carry the sludge to the Sinter plant for reuse
in the blast furnaces. Provisions have been made
to direct the waters to a settling pond at the ore
dock in the event of mechanical difficulties with
the thickener. This prevents any direct discharges
of untreated wash water from being discharged to
the river.
A new heavy duty rake assembly with scum
removal equipment is on order for the thickener,
which will improve the dependability and efficiency
of the unit. Delivery of the unit will be 12-14
months and will be Installed upon receipt of the
equipment.
4. Recirculating Water
Water is now being reclrculated in three
-------
820
V. W. Bacon
different locations, namely, the Blast Furnace -
Coke Plant, Open Hearths and Bar Mill Reheat
Furnace. The volume of water reused in these
operations amounts to 30 million gallons per day.
All cooling water used in The Open Hearth Furnaces
is recirculated. This amounts to 28 million gallons
per day, formerly taken from the Calumet River.
Cooling water for the 11" Bar Mill Reheat Furnace
is recirculated In a manner similar to that used
in the Open Hearth shop.
From this it is obvious that water conserva-
tion is a basic policy in the water management
program.
5. Scale Pits
All scale produced in the various rolling mill
operations is transfered to sedimentation tanks.
There are a total of 16 sedimentation tanks used
for the recovery of scale and oil. Modifications
have been made in the older basins to improve the
efficiency of scale and oil removal.
The 11" Mill Is equipped with automatic and
continuous scale removal and a new continuous
belt type oil skimmer is In operation on this
unit. The flume from the 10" Mill has been con-
-------
821
V. W. Bacon
neeted to the 11" Mill scale pit to utilize the
facilities of the automatic scale pit.
6. Sanitary Waste
All of the sanitary waste in the Chicago
District are discharged directly into the Sanitary
District sewer lines and none goes to the Calumet
River.
7. Coke Plant
The only water discharged to the Calumet from
the Coke Plant is that used for cooling and does
not come in contact with the waste streams. Waste
waters containing ammonia, cyanides, and phenols
are pre-treated prior to discharge to the Sanitary
Sewer System.
8. Air and Water Management
The Chicago District is a pioneer in estab-
lishing a department solely for the purpose of
air and water management.
This department was established in 1966 and
comprises the departments formerly under Combustion,
Steam Production, and Mechanical Departments.
Engineers are assigned to a continuous
program of inspection and education on supervisors
of the operating departments in good housekeeping
-------
822
V. W. Bacon
and water management. The department correlates
all of the activities of the chemical laboratory,
engineering, operations, and maintenance In con-
nection with the design and installation of water
pollution control facilities.
More than 2-1/2 million dollars have been
spent on pollution abatement facilities in the
Chicago District since 1958, illustrating Republic's
awareness of water pollution control.
CATALIN CORPORATION
Company installed temporary lagoons to handle
process wastes which were separated from their cooling
water. Analyses disclosed remaining effluent not of adequate
quality. Company did not fully cooperate with The Metro-
politan Sanitary District to resolve remaining problem and
were called In for a Show Cause hearing in January 1967.
Since the hearing the company has fully cooperated with the
Metropolitan Sanitary District and have accomplished the
following:
1. Plans for a sanitary sewer extension to
divert all concentrated process wastes to a
Metropolitan Sanitary District interceptor have
-------
V. W. Bacon 823
been submitted to The Metropolitan Sanitary
District and approved. Construction phase of
this project sewer contemplated by March 17,
1967. This system will discharge all process
wastes to Metropolitan Sanitary District facilities.
2. Developed plans for a new condensing system
to prevent the discharge of steam entrained
pollutants to the river. The new equipment is
on order and being fabricated. Shipment scheduled
for April 10, 1967.
FORD MOTOR COMPANY
Company has completed the installation of all
waste treatment facilities In February 1967 deemed necessary
to comply with Metropolitan Sanitary District requirements.
Minor adjustments are under way to facilitate operation of
their acid treatment system. In addition, the continued
program of good housekeeping is being maintained to eliminate
contaminants from being discharged to the river. Company
has no plans for any additional waste treatment installa-
tions, since it is their belief that the operation of the
existing facilities in conjunction with good housekeeping
will provide the degree of control to conform to the water
-------
824
V. W. Bacon
quality criteria established so far. Industrial Waste
Control Division to evaluate effluent within 30 days.
BULK TERMINAL COMPANY - LAKE CALUMET
Company installed a secondary waste water treat-
ment facility during February 1967* which is currently
operational. Their routine monthly analyses indicates
that the waste treatment facility is not performing at
expected efficiency. Industrial Waste Control Division
to evaluate effluent within 30 days.
GULF OIL CORPORATION
Company is using an earthen dike sludge pond
for the storage of process wastes. This facility is
Inspected once per shift to prevent any leakage to the
river. A private scavenger has been retained to pump
out ponds when they reach capacity. Occasional river
discharges due to pond leakage after intense rainfall.
They have entered into an agreement with the
Catalin Corporation to install a sewerage system to convey
their wastes to a Metropolitan Sanitary District sewer in
Calumet City. Construction of this project scheduled for
-------
825
V. W. Bacon
March 17, 1967. This system will discharge all process
wastes to The Metropolitan Sanitary District facilities.
GENERAL MILLS, INC.
Company has diverted all contaminating wastes
to the Sanitary Sewer. Only cooling water Is discharged
to the river. Final correction completed during latter
part of 1966.
UNITED CHEMICAL CORPORATION
Industrial Waste Control Division observations
and surveillance show no process wastes being discharged
into the river.
CARGILL, INC.
Industrial Waste Control Division's evaluation
indicates that the company's new waste control facilities
and good housekeeping programs still eliminate the discharge
of any wastes to the river.
ALLIED CHEMICAL CORPORATION - INDUSTRIAL CHEMICAL DIVISION
-------
826
V. W. Bacon
The company still maintains effluents that meet the
minimum requirements set forth In The Metropolitan Sanitary
District directive of August 18, 1965. To insure their
continuing to maintain satisfactory conditions, they have
Increased the frequency of their sampling monitoring pro-
gram. In addition, they have Instituted a formal program
to prevent accidental spills of process materials.
SWIFT AND COMPANY
Industrial Waste Control Division observations
indicated occasional discharges to the river, due to lagoon
leakage. The lagoons have been reinforced, eliminating
this problem.
CHICAGO BRICK COMPANY
Company has discontinued discharging waste
effluent to the river. This has been achieved through
in-plant control and incorporation of good housekeeping.
LIBBY MCNEIL AND LIBBY
Since this company has diverted their process
-------
827
V. W. Bacon
wastes to the local sewerage system, no wastes have been
discharged to the river. Wastes are pre-treated prior to
their discharge to the sewer.
GENERAL
All Industry in the Calumet Area have been kept
under constant observation and/or surveillance by the
Industrial Waste Control Division. This consists of
routine inspections and helicopter observations. In
general, our observations have shown a marked improvement
of the effluents discharged to the waterways in this area.
All industries discharging to the waterways in
this area, regardless of volume of flow and/or type of
wastes created, must-continuously submit routine effluent
analyses, on a monthly basis, to the Research and Control
Department for review of representative analytical data.

* * * * #
-------
V. W. Bacon 839
MR. STEIN: Are there any comments or questions?
MR. POOLE: I have one for my enlightenment.
It doesn't particularly help the record.
What kind of retention time do you have for that
chlorination at that 95th Street Station?
MR. BACON: In the slip?
MR. POOLE: I gather that is where the retention
was, in the slip.
MR. BACON: It varies between the pumps. It will
be somewhere between one hour to six or seven hours.
MR. POOLE: I see. In other words, it is a pretty
long time?
MR. BACON: Yes. It is 100 feet wide, 700 feet
long, and about 20-some-feet deep. With the storm pipes and
the dry weather pumps, it will be a little less than an hour,
as I recall.
We have good chlorine contact time and sufficient
settling, so that we are probably dropping out most of the
settleable solids. I don't know what state we are in now
for the skimming device, but we are planning a skimming device
for the area also.
Literally, we will be having primary treatment
with heavy chlorination.
MR. STEIN: Any other comments?
-------
840
V. W. Bacon
MR. KLASSEN: Just along that same line, Just
from a purely technical Information standpoint, what kind
of chlorine demands do you get? In other words, how much
do you feed relatively?
This is an interesting setup because of the rela-
tively long length of contact time. I wondered whether per-
haps we could discuss it later and not take the time here,
but I was just interested from a technical standpoint.
MR. BACON: We have not become that sophisticated
with this flow yet. We are using about 40 parts per million
of chlorine, using sodium hypochlorite. Under these circum-
stances, the cost of the chemical is not a controlling factor
I might volunteer that this has been encouraging.
They were going to put an identical installation at the
North Side Sewage Treatment Plant for chlorination of that
effluent with about seven and a half minutes detention with
forced gravity means to the North Shore Canal, and then see
what can be done in the canal itself as the contact basin.
It would save us millions of dollars in a couple of years if
this works.
MR. STEIN: Are there any further comments or
questions?
MR. POSTON: Mr. Bacon, in the South Works of
the United States Steel Corporation, what kind of a date are
-------
V. W. Bacon 8Z|1
you shooting for in terms of completion of waste treatment
works9
MR. BACON: Right now we would probably state that
they are about six months behind schedule. That is about the
best we can fix it.
Neither the president nor I were involved in any
way whatsoever in the program up until just recently. I am
speaking of President Egan. We have recently come aboard on
this industrial waste problem.
I am going to say a word for United States Steel,
because I think that there is a vast difference between when
you are talking about the Gary Works and the South Works.
I don't know how it is in the manufacturing or steel, but it
seems to me that in the water problem there is a difference,
and it is because of this.
I am going to use this chart for just a minute.
When O'Brien was put into operation, this made
this a lake (indicating). In other words, when the locks are
not working, are not operated, or when the sluice gates are
not opening, this, for all practical purposes, is a lake.
It is a very slowly moving lake.
It used to be when the lock was over here (indicat
ing) that the flushing all took place in this direction at
times, during storm and other times, but with the building
-------
V. W. Bacon
of the O'Brien Lock, now we have complete control, except
for minor circumstance, over this waterway.
Part of our program, as I have pointed out, has
been that we maintain an average of 350 cubic feet per
second in this action, and therefore we are pulling the
wastes this way (indicating) at all times during the critical
part of the year, and we hit it practically all of last year.
So, when we are not drawing that way, what is the
position of United States Steel? The position of United
States Steel South V/orks is that they draw water out of the
lake and go through this plant. We don't care whether they
put it in the river right here (indicating) or back in the
lake. It is in essence back in the lake, and they have to
make those stringent requirements for the lake which are
considerably higher than the requirements for here (indicating)
That is why I asked that question, in anticipation of this
explanation.
Do you follow me, Mr. Stein or Mr. Poston?
MR. STEIN: I have no trouble (indicating).
MR. BACON: This is actually a cycle here, and,
therefore, they are going to have to meet right at the shore
the criteria set by this conference, and those are tough
criteria to meet. We think their problem is so extremely
complicated and going to be so costly that we want to take a
-------

little more time too.
MR. STEIN: Yes.
Well, here you have talked about 16 industries,
Mr. Bacon. Do I understand your report that 13 of these are
on schedule and they are going to be completed by December
of 1968 and in operation?
MR. BACON: They are on schedule now as far as
the preliminary plans are concerned, and from what appears to
be, they will meet the schedule for the final engineering.
If they will fall down between now and the end of
1968, we don't know, but we are not anticipating that they
will.
MR. STEIN: But, as far as we know, they are on
schedule?
MR. BACON: Yes, sir.
MR. STEIN: And the other three steel plants, the
large steel companies — you didn't say three, did you?
MR. BACON: Yes, we did. We said the three.
MR. STEIN: Three are a little behind?
MR. BACON: As f?ir as we can determine now, we
would say six months.
MR. STEIN: Well, even with six months behind, if
they run six months behind and we have a date of December
1968 for it to be in opergition, six months behind would make
-------
844
V. W. Bacon
it July, say, or the end of June 1969, which would still be
ahead of what United States Steel said they were going to
do in Gary.
MR. BACON: I did not mean to imply that we are
extending that to the construction. I am talking about the
thing that we set the dates for, the plans and engineering,
and right now we would say they are that far behind on the
plans and engineering.
MR. STEIN: We understand that, but what I am
trying to get at is, is this an accelerating operation, or
do you feel that Just the six months won't accelerate it?
They are six months behind here. There shouldn't
be any indication that that six months should expand in the
future, should it?
MR. BACON: Mr. Stein, until we get their plans
and specifications, we have not asked them what the minimum
timetable can be on that construction.
As of now, we are assuming it can come close to
that schedule. They may come to us, as they did to the other
members of this conference, and say that they need more time.
We have not asked that question yet.
MR. POOLE: This may be an unfair question. If
it is, I will withdraw it, but —
MR. BACON: Go ahead and withdraw it.
-------
845
V. W. Bacon
(Laughter. )
MR. POOLE: You have listened to me and, I am
sure, you know pretty generally the problem of your steel
mills which you are discussing now.
Do you think we have been talking in too un-
realistic terms today?
I say I will withdraw it if you think it is an
unfair question.
MR. BACON: I think that is a conference decision,
Blucher.
I think all of us have individual professional
opinions on this, and opinions as to the reality of some
schedule. I think that is a conference decision.
MR. POOLE: Good answer, as usual.
MR. BACON: I want to make another comment.
When you talk about those 13 that are on schedule,
we had to cite one of them in for a show-cause hearing, and
it was a full show-cause-on-the-way-to-court hearing, and
then they promptly got on schedule, so we are going to use
our teeth when it is timely.
One of those 13 did not come easily by the
schedule.
MR. STEIN: Let me again, Mr. Bacon, go over
this. This is for clarification.
-------
846
V. W. Bacon
The December 1966 deadline was for preliminary
plans and specifications. They did not do this. Now, if we
have six months, that will be June 30, 1967, but your
sentence says It is doubtful that the large steel companies
will complete preliminaries by June 30, 1967.
If they are going to be about six months behind,
at least to me It would seem they should complete It by June
30, 1967. Does this indicate that they are going to be more
than six months behind?
MR. BACON: I don't know. You can't cross the
bridge until you get to it.
Although I was trying to illustrate to you, since
the endorsement of this was up to us in the District, if
this gets behind and we think it is not realistic, we are
going to move on it, just as we did on company No. so-and-so.
MR. STEIN: I recognize that, but what I am trying
to do Is understand what you said, and the position.
The point is, if they are running six months
behind, then the preliminary plans should be completed by
June 1967. If they are completed by June 1967* then I am
not sure, and I am asking for clarification, what the sentence
means where you say, "It Is doubtful if the large steel
companies will complete preliminary plans by June 30, 1967."
MR. BACON: This is our prediction, that the way
-------
847
V. W. Bacon
it is going they may not even complete their preliminary
plans by that time.
MR. STEIN: In other words, they are more than
six months behind?
MR. BACON: Yes, they will be then more, if that
happens; but, as I pointed out to you, the pressure that is
being brought to bear will be brought to bear even more in-
tensely.
MR. KLASSEN: This is just a technical question,
Mr. Bacon, but have you found in your Calumet River -- you
indicated how much like a lake it is - that wind directions
affect possible reversals, water going one way underneath
and another way on top?
I think you mentioned that at the last hearing.
What has been your experience?
MR. BACON: Right now, we just don't have devices
sophisticated enough to measure whether it is reversing or
not, although we believe we are going to be able to acquire
it, but what will happen if you have three or four per
second feet flowing in this direction (indicating) if the
wind suddenly reverses and goes offshore and drops the lake
by a foot, then from somewhere back in here out to there you
have a slope of about a foot, maybe over a half mile or over
a mile, so all the water that would flow in that direction
-------
V. w. Bacon
would not be the entire body, but the equivalent of that
thin wedge.
We just don't know how much that would be, and,
of course, frcn, a practical point too, we can't set this in
motion fast enough to overcome a wind. It takes quite a
few hours to get an increased diversion to be felt way back
at the mouth of the river.
MR. STEIN: Are there any further comments or
questions?
(No response. )
MR. STEIN: If not, thank you very much, Mr.
Bacon.
In talking to the conferees, we feel that we may
be pretty close to an announcement. We will recess for about
ten minutes..
If we find we are hitting any snags, we will send
word out, but if the conferees will go in through that door
to my right, we will confer, and I hope we will be out very
shortly.
(Whereupon a recess was had.)

Closing Statement - Mr. Stein
CLOSING STATEMENT
BY
MR. MURRAY STEIN
MR. STEIN: May we reconvene0
I am happy to say that the conferees have come to
a unanimous conclusion.
I will attempt to summarize the conclusion orally,
and then, of course, allow the conferees the opportunity to
suggest any modification or nuances I may not have caught
inside, so that we can have a complete record on the natter.
We all believe that considerable progress has been
made towards abating pollution, both by the municipalities
and the industries concerned. I think the progress here is
in full flight. We are having as much progress as you can
have in any area of a clean-up program, and I think those of
us who are professionals in the field can sense when there
is a clean-up program under way, and that is under way here.
We also recognize the difficulty that some of the
municipalities and industries are having in meeting the time
schedules, and because of the nature of the water and, I
think, the conscientiousness of the technical staff, both
the water quality requirements and the treatment requirements
-------
850
Closing Statement - Mr. Stein
and the time schedules, as you can appreciate, are rather
tight.
As a matter of fact, the water quality require-
ments, except for certain kind of specialty waters such as
Lake Tahoe, are probably as high as you will find anywhere In
the country.
Recognizing this, and recognizing that thr State
agencies and al] of us under other aspects of the program
have to establish action programs for all waters, the
conferees have unanimously agreed that for the present time
there will be no change in the time schedule which has been
previously announced.
However, the conferees have scheduled another
progress meeting for September 6th of this year in Chicago.
At that time, the conferees wil] have the benefit
of the State action programs, we hope, and will have the
benefit of evaluating the progress of the industries and the
municipalities in this area.
We recognize that many of the industries and
municipalities are making a valiant effort to meet the time
schedule established by the conferees and the water quality
requirements established by the conferees.
I think it behooves them to demonstrate in the
next six months that they are making this effort. If what
-------
851
Closing Statement - Mr. Stein
has to be done is the development of -engineering plans, the
Job is to go out and get consulting engineers, or other
technical staff, and get it.
The conferees, of course, will consider the
progress at the September 6th meeting, and the question of a
reasonabJe date of compliance will be opened for discussion at
that time. I think we will be in a much better position to
make the Judgment on reasonable dates of compliance when we
have all the facts that the State program and the District
are going to develop in establishing action programs and
standards between now and that time, and, Just as important,
by evaluating the progress that the industries and municipali-
ties have made.
If they have made a bona fide attempt to move
their program forward as rapidly as possible, and this very
well will show up by September, we will again reconvene and
determine how far ahead we have to move in order to keep the
program on schedule.
The present schedule is being maintained so that
we will give all the dischargers every opportunity to get
on the track, and, of course, we will be sympathetic, but I
think a good faith showing must be made in six months that
they have made every attempt to move this forward.
In large measure, I think we should recognize
-------
852
Closing Statement - Mr. Stein
that by and large the program is on schedule, and considering
this to be a complicated municipal-industrial area, that takes
second place to none in the complicated nature and the diffi-
cult technical nature of the problem, which is indeed an
achievement.
As a matter of fact, I would say that given any
major municipal and industrial program that I have been
connected with — and there have been quite a few -- the
adherence to the schedule in the Chicago metropolitan area
is at least as good as anywhere else, and perhaps better than
most.
I will ask the conferees if they have anything to
add.
MR. POSTON: I have no comment.
MR. KLASSEN: No.
MR. EGAN: No.
MR. POOLE: No.
MR. STEIN: If not, I would like to thank you all
for coming and staying with us. I think we have achieved
quite a lot.
We stand adjourned until September 6th.
(Whereupon, at 5=55 p.m., the conference was
adjourned until September 6, 1967. )
