                  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

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,

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 21ฐ and 23ฐ  during the summer  months



 of  1966 and  between  16ฐ and 15ฐ 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

                      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 6ฐ 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

                    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

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

                     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

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

brane filter technique using MSC media as  per  "Standard



Methods"

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

                     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.

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

 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.

and the Cal-Sag Channel waterways.  The samples for these
analyses were taken mainly from the District boat and do

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                          ฐ9



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

                     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 2ฐ or



3ฐ 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

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 6ฐ 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 35ฐ C.  Downstream of this station,


temperatures  tend  to decline slightly to mean values of


19ฐ C. in summer,  13  C. in spring-fall and 6ฐ 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 oฑ 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.

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,

-------
                                                     630
                    V. W. Bacon

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 22ฐ 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 29ฐ C. with a




mean value of 28ฐ C.  During the summer period of 1966 the



temperature ranged between 16 to 25ฐ C., with a mean value of




22ฐ 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 2ฐ 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

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.

                    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

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.

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

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  "


          J -  4.2   "                D -32.2  "


                 average  - 7.5 cfs


Note:   *Chlorination of by-passing began at the pumping


         station  In July   1966.


          At the minimum, discharge at the O'Brien  Lock was


19  times the by-passing at the pumping station  (December).


          This type  of operation  Insures  that undesirable


wastes discharged to the  waters of the Calumet  River are


continuously moved downstream away from  Lake Michigan.

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.

           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

 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

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

          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

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.

the executive session of January 31* and February 1, 1966:
          1.  Preliminary engineering planned documents
               completion - December  1966.
          2.  Final engineering plans documents completion -
               June  1967.
          3.  Construction completion with facilities in
               operation - 1968.
          These documents are to be filed in sufficient
time so that they may be approved by The Metropolitan
Sanitary District in conformance to the aforementioned dates,
          The conferees recognize that modifications in
this schedule may be necessary and these may Include:
          1.  A  lesser time when the Metropolitan Sanitary
               District considers a practical method of
               control can be in operation prior to the
               time  stated.

           2.   In a few  Industries  some variations  from  this


                schedule may  be sought from  the Metropolitan


                Sanitary District.   In such  cases,  after


                review,  the conferees may make appropriate


                recommendations to  the Secretary of the


                Department  of  Health, Education and Welfare.

           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

-------
                     V. W. Bacon



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.

            (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.

           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

               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

              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

             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. )
