            A CRITICAL REVIEW OF THE LITERATURE  OF 1957

                Pollution Surveys and Investigations


       Cooperative state-industry stream studies are being carried out

on several rivers of Wisconsin (20U).  Chemical, physical, and biological

conditions in the Fox River below Lake Winnebago, were studied intensively.

It was found that some stretches of the river may receive as much as

UOO tons of organic matter per day; that sludge deposits are formed, and

that in some sections D.O. is reduced to critical levels.  Graphs of D.O.

concentrations indicate that lethal levels for fishes are reached in one

area.

       A Fish and Wildlife Service report (I8li) points out that pollution

of the Delaware River in the Philadelphia area prevents its use by shad

as a spawning and nursery area.  Pollution has been most severe on the runs

of shad in recent years, affecting spawners during the upstream migration
                                            r-4
and both young and adults on their downstream migration.  The Delaware

River fishery for shad has declined from a peak production of

19,000,000 Ibs. in 1896, to a level at which it is economically unfeasible

for fishermen to operate.  Apparently the decline is due primarily to an

-------
                                 -2-





oxygen block between Torresdale and Marcus Hook where the D.O. falls to



zero or near zero in the late summer.  The period of low flow, low D.O.,



and downstream migration of juvenile shad occur simultaneously in Sep-



tember and October.  There is also a high mortality of spawned out fish



as only 1.7 percent of adults are repeat spawners while in other



Middle Atlantic streams the percentage is 3^.6 to £l percent.



       Many statewide surveys are being carried out through the use of



Dingell Johnson funds.  These serve to indicate the condition of streams



and of fish populations.  Hulsey (86) reports that the Red River watershed



is the most seriously polluted area in Arkansas.  Oil field wastes pollute



111!? milesj silt and shifting sand pollute 136 miles, paper mill wastes,



110 miles, phenolic compounds, 2£ miles, and barite mine seepage waters,



20 miles.  The Arkansas River watershed is the second most polluted with



silt and shifting sand being the main pollutant.  In the Russell and



Levisa Forks of the Big Sandy River in Kentucky, pollution is due to coal



washings, acid mine waters, sewage, oil, silt, and sawdust«  In some



sections of the streams coal deposits are four feet deep (101).  Electric



seining operations indicated that U5 species of fish were present in these



streams.



       A survey of the Bhadra River of India (lj.J>) indicated extensive



biological effects of industrial pollution.  Fish found dying below paper



mills had not been feeding as their digestive tracts were empty.  A stror^,



mixed odor of sulphides, sulphonates, and chlorine emanated on opening



these fishes.  Heavy sewage pollution in the Schliersee brought about a



deterioration in condition and a decrease in numbers of ihe fish (169).

                                 -3-




The fish which were examined showed signs of starvation.   Vivier found that


a rayon plant on the Sorame increased the mineral content  of the  stream


and encouraged slime growths which at times broke loose and caused sudden


fish kills (196).  The discharge of organic wastes into lakes brought


about a decrease in the oxygen content of the deeper waters and  caused the


near disappearance of salmon in Lake Eguaon and Annecy.  Lake Leman is


affected most by the sewage of Lausanne which has caused  a putrid slime


deposit on the bottom about 60 cm. deep.


       Hawkes (75) presents and illustrates the use of a  biological


method of classifying the pollution of streams.  He stresses the need for


complementary biological and chemical examinations in all surveys of


pollution and points out that biological examinations have shown rivers


to be seriously polluted by toxic substances which were only subsequently


detected by chemical tests that were not practiced on a routine  basis.



The Freshwater Biological Association (British) in its 23rd Annual Report


describes its continuing studies of pollution and the aquatic environment


(8).  These studies deal with water movements in stratified lakes, the


source of dissolved solids, factors governing the abundance of algae,


composition of lake muds, and population studies of fishes and invertebrates,


       In Great Britain there are several river boards which make annual


reports on their surveys and investigations.  These reports contain much
                                              -4

valuable information on the effects of pollution and the  benefits of


various abatement methods.  In their 1956 report (5) the  Bristol Avon


River Board gives information on water use, floods, waste discharges,


pollution abatement, stream classification, waste treatment, fisheries,

-------
                                 -k-






and toxicity.



       Reports on pollution abatement and research activities in several



areas were made at the Seminar on Biological Problems in Water Pollution



at the Robert A. Taft Sanitary Engineering Center and are included in



the Transactions of the meeting.  Research activities in Great Britain



were summarized by Beak (17) who pointed out that the research program is



shaped to meet the requirements of the 1951 River Pollution Prevention Acts



with special emphasis on standards of purity to be established.  One team



has been carrying on fundamental research on the toxicity to fish of



various chemicals, particularly CN, 002, anc* ammonia.  Another team has



been carrying on field studies of pollution biology, particularly as



pertains to fishes.  In Ohio, the Division of Wildlife is responsible for



the protection and preservation of wildlife and thus the majority of their



studies are concerned with fish kills.  An intensive study is being made of



the effects of acid mine drainage in the Racoon Creek basin and possible



corrective measures are under test.  Studies are under way on the Little



Miami River to determine improvements, resulting from sewage treatment (l£8



       In British Columbia, studies of the effects of wastes from forest



products industries on the marine environment are being stressed (198).



In Ontario, the most intensive investigation has been on the Spanish River



where it was found that the deposition of wood fibers was of prime



importance in the elimination of fish food organisms over an extended



area (llj.1).  The mining industry has also created problems due to ore



pulverizing wastes which have produced turbidity and unstable bottom



conditions.  The mining of uranium ores has added new problemsy namely,

-------
highly acid wastes and toxic mstals.  Methods for the control of blue


green algae by the removal of phosphorus have been developed and tested.


Routine stream surveys are now complete in Wisconsin and more intensive


studies are now being made on the major waterways.  These have indicated


that studies during the winter period are of importance (129).  A cooper-


ative program of investigations in water pollution biology is being


carried out by the Dept. of Fish and Game Management of Oregon State


College and the Robert A. Taft Sanitary Engineering Center of the Public


Health Service,  Complementary field and laboratory research designed to


provide basic information on pollutional problems in fresh and marine


waters is under way.  Current field studies include physical, chemical,


and biological investigations of polluted streams and studies of small


streams, experimentally subjected to controlled pollution.  Artificial


stream studies are being used to evaluate the effects of low level


pollution and studies are in progress on the influence of D.O. upon the


survival, development, growth, activity, and movement of fresh water


fishes (200).  The relation of the various fish and game programs of the


Fish and Wildlife Service to the pollution problem was described by


Meehan (131).  Acid mine drainage, mining wastes, oil pollution, lumbering


operations, pesticides, water development projects, and domestic and


industrial wastes all may have adverse effects on large segments of wild-
                                              •«•*••

life populations.  In the Missouri Basin wastes from the processing of


agricultural products are the main pollutants.  Other sources of industrial


wastes are oil fields, refineries, steel mills, and chemical plants.


An unusual fish kill in the Yellowstone was directly occasioned by aerial

spraying with DDT to control spruce budworm in the headwater areas (ll|.0).

                             Fish Kills






       The use of a 30 percent DDT concentrate in an emulsifiable oil with



0.5 percent "Lissapol" as a spray to control Tanytarsus lewsii in the



Nile above Khartoum, resulted in an extensive fish kill.  Labea were



killed in 8 hours and Synodontis in 36 hours (2U).  Low oxygen levels



during the night and early morning hours due to excessive growths of



aquatic vegetation were responsible for heavy fish mortalities in



Madras State (30).  A similar kill in a temple tank resulted from a



heavy growth of Micro'cystis aeruginosa (193).  Methods for the investi-



gation of fish kills and steps to be taken when such a kill occurs are



outlined by Liebmann (117).  In their "Fish Conservation Highlights of



1956" Stroud and Seaman list damage to fish populations throughout the



country by various pollutants„  Insecticides are becoming of increasing



importance in fish kills (181).

              Water Quality Criteria for Aquatic Life





General



       Since the purpose of water quality criteria for aquatic life  is  to



maintain conditions which are favorable for aquatic organisms  they must



be based on knowledge of the environmental requirements of these organisms.



While much is known concerning the environmental requirements  of the



aquatic biota much remains to be learned.  Ecological, life history, and



environmental studies are, therefore, pertinent and valuable.   Studies



carried out in Belgium have lead to the conclusions that:   alkaline  waters



are most favorable for fishesj the optimum pH is between 7.0 and 8.0



although values of 5.0 to 9.0 are tolerated^ water passing over granite



rocks is usually acid and not favorable for breeding] D.O. content is very



important and should be fairly stable throughout the yearj trout require



more oxygen than do carp and tench, and the optimum water temperature for



trout breeding is 15° to 17° C. and for carp, 20° to 25° C. (85).  A study



of mayflies in Douglas Lake, Michigan, has shown that Hexagenia nymphs



are limited by the oxygen concentration to that portion of the mud bottom



above the level of the hypolimnion(125).



       In a general discussion of the subject, Tarzwell (185) states that



while much remains to be learned, enough information is now at hand for



the setting of tentative criteria.  It is suggested that pH values should



not.fall below 5.0 or exceed 9.5, but for good production they should be



maintained between 6.5 and 8.5j that for Salraonoid fish 6.0 p.p.m. of D.O.



is desirablej that for a well rounded warm water fish population, D.O.

-------
levels should not fall below £.0 p.p.m. for more than 8 hours out of a
21; hour period, and at no time should they fall below 3 p.p.m. while for
coarse fishes they may drop to 2 p.p0m0j for warm water fishes temperature
should not exceed 93° F. in the northern portion of the country or 96° Fa
in the south, and for trout best production is obtained in streams having
summer temperature of 60° to 68° F.  It is suggested the amount of toxic
wastes which can be added to a specific stream should be determined in
each case by means of bio-assay.
Suspended Solids and Turbidity
       Studies in Oklahoma (23) revealed that high turbidities reduced
the growth and yield of bass and bluegills and favored the production but
not the growth of channel catfish.  Clear reservoirs attracted more
anglers and yielded greater returns per unit of fishing effort as well as
more desirable species of fishes.  Experiments in clear ponds, turbidities
less than 2£ p.p.m., intermediate ponds, turbidities from 25 to 100 p.p.m.,
and muddy ponds, turbidities over 100 p.p.m., showed that the average
total weight of the fish in the clear pond was 1.7 times that from the
intermediate pond and £.£ times that from the muddy pond.  Wilson (207)
reviewed the literature on the destruction of aquatic life by turbidity
and silt and presented evidence of lowered productivity due to the
screening out of light and the abrasive and smothering action of sediment
on the bottom fauna and fish eggs.
Temperature
       Experimsnts to determine the effects of temperature on the
respiratory movements of carp indicated that the upper lethal temperature

-------
                                 -9-




is lower for the older heavier carp than for the smaller younger fish


which showed little change in respiration rate over a temperature range


of IS0 to 35>° C. (13U).  Experiments with guppies have shown that in fresh


water the optimum temperature range for growth is 23° to 2£° C. and that


growth in 25 and £0 percent sea water is greater than in fresh water (65).


The upper temperature threshold for the normal development of Chinook


Salmon eggs was found to be 57.5° to 60° F. while the lower threshold was


liO° to 1*2.£° F. (37).  It has been experimentally demonstrated that lobsters


can be acclimated to certain temperatures, acclimatization for transfer


from Hu5° C. to 23° C. being completed in 22 days.  Moulting lobsters


are less resistant to high temperature, low salinity, and low D.O. -than


are hard-shelled lobsters.  The upper IB thai temperature was raised by an


increase in thermal acclimatization, lowered by a decrease in the level of


oxygen acclimatization, and lowered by acclimatization to reduce salinity


(128).


Dissolved Solids and pH


       Since the war industrial plants on the Werra River of Germany have


been discharging large amounts of chlorides and have brought about fish


kills in 19l*9,  that were  positively correlated with the increase in the


salt content of the river water.  Fish that were moribund recovered when


placed in polluted water  that was diluted 30 percent with tap water.
                                              ««i

Fish kills  occurred in winter when  the salt content exceeded 12,000 p.p.m.


The next spring surveys showed that fish were absent from the river


immediately below the  industrial concentration.  The resistance  to salinity

-------
                                -10-





is greater at lower temperatures.  The insect larvae disappeared from the



more saline regions and there was a reduction of fish food organisms



(170).  A year round study was made of a prairie stream polluted with



brine wastes from oil wells and in which the concentration of chlorides



ranged from 20,000 p.p.m. at the headwaters down to 100 p.p.m.  The 3h



species of organisms found in the stream throughout the year are arranged



according to their chloride tolerance.  Fish were present only in the



section having chloride concentration of 100 to 1000 p.p.m. (3k).

Dissolved Oxygen and COg



       Experiments were carried out to determine the respiration of aquatic



animals at different rates of flow and the relation of the lethal oxygen



tension to til e rate of flow and of the oxygen demand of larvae to the



oxygen tension and the rate of flow (91).  In experimental studies with



caddis fly larvae, it was found that larvae normally inhabiting riffle



areas are readily immobilized at a relatively high oxygen concentration in



still waters but can tolerate low oxygen concentrations in flowing water



comparable to levels tolerated by the species found in pool areas (152).

-------
                                -li-





lt was found that goldfish acclimated for several days to low D.O.



levels, could withstand considerable lower D.O. concentrations than



goldfish which had not been acclimated.  The goldfish acclimated to low



oxygen had increased hemoglobin and higher red cell counts and a lowering



of the oxidative activity of some tissues (15>3>),  The maximum lethal



concentration of D.O. for yellow perch during short exposure periods



varied from 0.77 p.p.m. at 53° F. to 1.3k p.p.m. at 70° F., as determined


by turnover in a sealed container (26).  It has been shown that concen-


trations of C02 which sometime occur in polluted streams can more than



double the minimum concentration of D.O. necessary for the survival of



half the rainbow trout during a 2li hour exposure period.  In solutions



containing up to 67 p.p.m. C02, survival times are shortened by an



increase in temperature from 12.5° to 19.5° C. (2 )•


       Studies of winter kills on six southern Minnesota lakes lead to



the conclusion that the dissolved oxygen level is the best basis for fore-
                                                               f

casting winter kills.  High concentrations of C02, H2S, and ammonia are



concurrent phenomena of low oxygen conditions and are not the cause of the



kills, (172).  In connection with a fish kill below a kraft pulping plant,



field bio-assays were run to determine the toxicity of free chlorine



(Cl2) at different D.O. concentrations.  It was found that 0.2 p.p.m.



C12 killed all the test fish at D.O. levels of 1.0 to 2.0 p.p.m. but did
                                              -4

not kill fish at 5.0 p.p.m. D.O. (15).  The resistance of several species


of fish to low D.O. concentrations was tested at temperatures of 10°,



16°, and 20° C.  Rise in temperature reduced the resistance of all species

-------
                                -12-

tested to low D.O.  Tench were the most resistant to low oxygen and
in general trout were the most susceptible (U8).

Toxic Wastes,
       Methodst  Bio-assay procedures are not in wide use for the determi-
nation of the toxicity of wastes and other materials to fish and other

-------
                                -13-




aquatic organisms.  Work is also under way to develop methods for using


the results of short time tests to indicate safe concentration under


conditions of continuous exposure.  Studies are being made of a great


variety of toxicants and the influence of various environmental conditions


on their toxicity.


       Burdick (2JJ) suggests that the curvature found in logarithmic plots


of concentration against time for death in toxicity studies is induced


by failure of the effective range to conform to the axes of the paper.


Translation may be effected by subtracting the threshold value from


concentration and a minimum time from death time.  When this is done the


curve becomes a straight line and represents a simple inverse proportion.


A graphical method is presented by which these corrections may be approxi-


mated and an equation for the original curve derived.  The value of this


procedure lies in the evaluation of the threshold concentration which may


be used to establish safe disposal rates for toxic wastes.


       Jferkens has described an apparatus which  can be used with very


little manual attention to vary independently the temperature, pH, D.O.,


and concentration of toxicants in water supplied to six specially designed


aquaria (132).  Halsband developed, a method  for  assessing the toxicity of


substances in water through changes in respiratory rates.  Fish are kept


in a constant flow of water in a dark  pipe.  Their respiratory movements
                                             .-••-I

are measured by a new electrical method first  in normal water and then


after the addition of the toxic substance  (71).  As the result of tests


carried out in Belgium, the value  of bio-assays  in assessing water quality

-------
                                -Ill-
is discussed.  It is concluded that fish toxicity tests are of use for


determining the effect of a given effluent on fish in a river and the


dilution or degree of treatment required to prevent fish mortality (111).


A field technique has been developed whereby the concentration of sodium


pentachlorophenate in natural waters can be determined by observing the


mortality rate of the common guppy and comparing it with standard mortali-


ty curves developed for known concentrations of the material under


conditions encountered in the field (102).
                    *

       Henderson points out (76) that the toxicity of mixed industrial


wastes cannot generally be estimated from chemical composition.  It is


necessary to conduct bio-assays with the mixed waste using for dilution


the water from the receiving stream or water with similar characteristics.


Further a numerical value called the application factor, must be developed


and applied to the TLm derived from short time tests to indicate safe


concentrations for aquatic life under conditions of continuous exposure.


In developing the application factor major consideration is given to


relating the test to actual conditions, the test fish to other aquatic


life, and to possible effluent fluctuations (76).


       Garrett (61) points out that it is becoming increasingly important


to obtain biological information on a waste problem and in many cases


this information is as important as chemical and engineering data.  Bio-


assay data on wastes from a Monsanto Chemical Company plant were used in


the design of waste treatment facilities.  One-tenth of the 2k or lj.8 hr.


    was set as the effluent standard.  In another article (62) the same

-------
                                -15-
author points out that the most serious toxicity problem facing a manu-



facturing plant in providing for waste discharges is concerned with the



effects on aquatic life.  One of the principal reasons for this is that



the appearance of dead fish in a receiving stream has long been considered



the ultimate evidence of bad industrial practice.



       The use and value of bio-assays in meeting toxic industrial waste



problems, methods, equipment, supplies, procedures, and costs for carrying



on bio-assays, and the use of bio-assay results in meeting specific



problems are described by Henderson and Tarzwell (77).  Several examples



are given of the use of bio-assays by industry in the safe disposal of



toxic wastes.  Conventional physical and chemical tests of the effluent



of a large synthetic fiber plant gave no evidence of serious pollution.



Bio-assays showed this effluent to be highly toxic to fish under minimum



river flow conditions and also helped to locate the major toxic component.



Attention to the elimination of this material in the treatment process



restored the aquatic life of the river in a short time.  According to an



article by Vinogradov (19U) the sanitary authority of the U.S.S.R. is



meeting toxic waste problems by limiting the concentration of  certain



substances which may be discharged.  The limit for lead, copper, nickel,



cyanide, and chromium is  0.1 p.p.m., and for other materials is as follows:



picric acid, di- and tri-nitrotoluol, dinitrochlprobenzole, tetrfcnitro-



methane, 0.5 p.p.m., mercury, 0.005, arsenic 0.05, carbon disulphide 1.0,



fluorine 1.5* carbon tetrachloride  5.0, DDT 0»2, dinitronaphthalin 1.0,



dichlorethane 2.0, and  chlorine 0.0 p.p.nu  This, approach disregards the

-------
                                -16-





quality of the receiving water, synergy and antagonism, wastes already



present, and size of the receiving stream but gives strict and uniform



regulations which are easier to enforce.



       Tests indicate that the time of response of fish to Sarin decrease



relative to decreases in the D.O. content of the water.  Fish used in the



studies were fathead minnows, green sunfish, and goldfish (203).



The toxicity to Gambusia of 86 compounds which may occur in oil refinery



wastes was determined by means of bio-assays.  Because the waters of



Oklahoma, which were of chief concern, are mostly turbid, bio-assays were



conducted in turbid water.  The results seem to suggest a protective



action of the turbidity (199).  For that or some other reason some of the



results are at variance with those obtained by other workers.  For some



years bio-assay tests have been carried out in an effort to find a specific



toxicant for the larvae of the sea lamprey, Petromyzon marinus, in the



Great Lakes area.  Tests were made with the lamprey > rainbow trout, and



the bluegill.  Of the h,k36 chemicals so tested, 26k were toxic to only



one species and 333 were toxic to only two species (ill).  This work has



lead to specific materials for the control of the lamprey larvaej namely,



the Nitrophenols.



       Metals;  Extensive experimental studies of the effects of dilute



solutions of toxic substances, discharged into the Kama River, on various



types of river bottom animals indicated that 0.01, 0.002, and 0.001



normal solutions of KgC^Oy were lethal in 25, Ii7, and 67 minutes re-



spectively, to Daphnia pulex.  Similar tests were made with

-------
                                -17-



methyl violet, and other industrial wastes.  Among other harmful industrial


wastes are those from dye plants, coke plants,  oil refineries, soda works,


paint factories, and fertilizer works (18?).  It.was found that a
                                                \

5 x 10"^ M. sea water solution of uranyl nitrate inhibited the formation


of the fertilization membrane in Urechis eggs and lead to polys penny


(103).  These findings indicate that in determining the effects of toxic


materials more than lethal effects should be considered.  Experiments with


chum salmon, Oncorhunchus keta, 3.9 to f>.8 cm. in length in salinities of


17.9 to 18.1 p.p,t., at temperatures of ll|.U° to l£.0° C., and at D,0. level


of 8£ percent of saturation, indicated a 1*8 hr. TI^ value for AS2CU of


11 p.p.m. (U).  There is now experimental confirmation of the hypothesis


that metallic cations are toxic because they combine with an essential


sulfhydryl group or a key enzyme.  It is assumed that the affinity of the


cations for the sulfydryl group is a linear function of the insolubility


of the corresponding metal sulfide.  Ifetal ions that form the most insolu-


ble sulfides will also be the most toxic.  Experiments carried out with


distilled water indicate that the metals, listed in their order of toxidLty


are as follows:  Ag, Hg, Cu, Cd, Pb, Zn, Ni, Co, and Mi (175).  Experi-


ments with fish spawn, young fish, and Daphnia showed that Zn plates


placed in hard well water did not form poisonous salts but such salts were


formed in soft water ponds which were toxic (15U).  Other experimental


studies indicated that temperatures as well as hardness, influence the


toxicity of Zn.  In soft water the 96 hr. TI^ was 2.86 p.p.m. at 18°C. and


1.93 p.p.m. at 30° C.  In hard water it was 10.13 p.p.m. at 18° C., and

-------
                                -18-





10.15 p.p.m. at 30° C. (29).  Bio-assays to determine the effects of



various Cu and Hg compounds on Artemia salina, Elmihi'us modestus, and



Acartia clausi indicate that the latter two were more sensitive than



Artemia to all the materials tested.  The mercuric compounds were more



toxic than Cu to Artemia.  Mixtures of the two materials gave a synergistic



effect.  Exposure of Artemia to Cu rendered it much more sensitive to



subsequent exposure to HgCl2, but not to Cu.  The opposite was also true



(ill).  Additional studies demonstrated that the toxicities of primary



alkylmercuric chlorides become considerably less when cystine and reduced



gluthathione are added to the toxic media.  In general, a good measure of



agreement has been found between the relative lipoid solubilities of both



primary and secondary alkylmercuric chlorides and their respective



toxicities to Artemia (14.2).  Many toxic materials are not avoided by fish.



Studies were made on the effects of periodic low oxygen and it was found



that when the D.O. was lowered to 2 p.p.m. for 2 hours in each 2lj. hr.



period the materials under study become considerably more toxic: KCN about



h times, Naphthenic acid, 2.5 to 3 times, and ZnCl2 about 1/3 more (28).



The accumulation of Zn   in the clam, Meretrix meretrix, was high in the



gill, mantle, viscera, and other soft tissue, but there was very little



in the shell.  About liO percent of the radioactivity was lost in 2 days



after removal to normal sea water.  With the carp much of the radio-



activity was deposited in the gills and kidneys as was the Zn"5 injected



into the muscles.  After U8 hours, Sr"   injected into the muscles was



found largely in the hard tissues^ whereas Cs1^ was chiefly retained in

-------
                                -19-





the heart and kidney and found in both soft and hard tissues  (165).



       Phenol;  Experiments with fractions of the black  liquor from the



sulphate process demonstrated that there was no relation between phenolic



concentration and toxicity and that the most toxic fraction was the



residue after distillation, which contained no phenols (21).



       Ammonia;  Bio-assay studies with un-ionized ammonia indicated



that the period of survival for all species decreased as the  concentration



of the toxicant increased, decreasing D.O. increased toxicity with the



greatest effects at the lower concentrations of un-ionized ammonia.



Resistance of perch and roach to lack of D.O. was not significantly



affected but that of rainbow trout was reduced significantly by a small



concentration of the un-ionized ammonia (133)*



       Paper Mil Wastes!  Sockeye fingerlings, Oncorhunchus  nerka,  were



exposed to various concentrations of full bleach kraft effluent under



experimental conditions simulating those anticipated in the estuary of the



Somass River, British Columbia.  At 17.8° C. in sea water of  20 percent



salinity, the limiting concentration of toxicant below which  survival was



complete and independent of length of exposure, was U.8 percent.  However,



when D.O, requirements for respiration and oxidization of the waste were



considered, it was necessary to lower the concentration of the waste



effluent from U.8 to 2.5 percent (3).  In studies carried on in Japan it
                                             . --4


was concluded that the harmful effect of paper mill wastes on aquatic



organisms is mainly due to active Cl2 in the effluent from the beater,



in sediment of the bleaching liquor tank, and in the effluent from the

-------
                                -20-






factory (95).



       Detergents:  In an investigation of detergents it was found that



toxicity was mainly due to alkyl-aryl-sulphonate and that about 3 p.p.m.



of this material produce a 50 percent fish mortality in about 12 weeks.



When they are present more D.O. is required to sustain the fish.  It is



stated, however, that detergents do not constitute a threat to fishes (79)«



       Other Toxicants;  Aquatic animals can tolerate concentrations of



tannery wastes up to U percent when chromates are not present.  The tox-



icity of tannery wastes is attributed to reduction in B.O., changes in



salt concentration, and changes in acidity (209).  Latex tubing used in a



recirculating experimental apparatus in which the water was not exchanged



proved toxic to stonefly nymphs.  In jar tests the tubing caused the



death of stone flies in 72 hours and small Chinook salmon in 2ii hours



(U6),  A three year study of fish populations in White Oak Lake which



received radioactive and chemical waste waters from Oak Ridge National



Laboratory showed that fish in the lake grew more slowly and did not live



as long as fish in nearby reservoirs of the T.V.A.  Radioassay indicated



that radioactive materials were selectively concentrated in all tissues



of the body.  Radioactive Sr and P were found in the hard tissues and



Cs and the rare earths in the soft tissues.  The total radiation received



by the fish was estimated to be 5>7(rep)per year from external radiation



and several times that amount from internal radiation (10U).  Fast swimming



carnivorous fish fed Sr ° excreted most of it in a few hours.  The remain-



ing Sr ' was found mostly in the skeleton.  Excretion was much slower and

-------
                                -21-





retention much higher in a small sluggish herbivore.  About three times



as much Sr was found in the muscles of injected tuna as in those receiving



the isotope orally while the gills had only half the activity  found in



orally fed tuna (19).  When capsules containing £.£ ^ic. of Y7*1 were placed


                                                          91
in fishes stomachs it was found that the rate of loss of Y7  was very



high, only 2 percent of the dose being retained after two days (20).



Insecticidest



       The widespread use of the new organic insecticides and their



increasing significance as water pollutants are indicated, in the literature.



The use of these materials for area control has resulted in several



extensive fish kills and a reduction in the fish food organisms.



The number and volume of aquatic insects emerging from tributaries of the



Miramichi River of northern New Brunswick, where forest-covered watersheds



had been sprayed from the air with 0.5? pounds of DDT per acre, were



compared with insects emerging from unsprayed streams.  It was found that



there were fewer kinds of insects in the sprayed streams with the greatest



reduction occurring in the larger species which are the main food of the



young salmon (87).  A sudden complete mortality of landlocked salmon



fingerlings in a commercial fish hatchery was believed to be due to



aerial spraying with-DDT.  Bio-assay studies showed that landlocked salmon



are more sensitive to DDT than either rainbow or brook trout.  Low D,0.
                                             -4 .      ......


levels .increase the toxicity of DDT.  Under conditions of oxygen satu-



ration, 0.08 to 0.16 p.p.m., DDT is lethal to landlocked salmon but sub-



lethal for rainbow and brook trout (73).  Two applications of BHC, DDT,

-------
                                -22-






and Strdbane at the rate of 0.1, 0,2, and 0.3 pounds per acre respective-



ly, were made to the tidal marshes of Bombay Hock National Wildlife



Refuge.  At this low rate of application no damage of consequence was



observed from the two applications, with the exception of that to the



marsh fiddler crab (6k}•  Bio-assay tests with toxaphene indicate a



three-fold increase in the toxicity to bluntnose minnows when the tempera-



ture is raised from 5>0° P. to 7?° F.  Toxaphene was found to be more toxic



to the bluntnose minnow than to some of the aquatic invertebrates.



In treated lakes many groups of invertebrates were killed but they reap-



pered while the lake water was still toxic to fish.  Detoxification in



water proceeds more rapidly when it is exposed to light and where the



temperature and D.O. were high (8U).  In July 195$, the U. S. Forest



Service sprayed 132,8£6 acres of the upper Yellowstone River drainage with



approximately 133,000 pounds of DDT for spruce budworm control.  First



observations of dead or dying fish in the area were made in mid October



19£5*  Mortality was extensive but predominantly whitefish were affected.



Dead fish were in an emaciated condition and it is believed death was due



to reduced food supply.  Comparison of sprayed with unsprayed areas



revealed a noticeable absence of stoneflies, caddis flies, and mayflies



in the treated area (Ili7).  Bio-assays were made of the runoff water



from an experimental plot before and after treatment with dieldrin.



It was found that the runoff from the first rain from an area treated with



dieldrin at the rate of £ lb. per acre was toxic to fathead minnows in a



one in three dilution.  Some toxicity to fish was still present in runoff

-------
                                -23-





from the third rain after treatment (186).  The application of approxi-



mately 0.1 p.p.ra, of toxaphene had a marked detrimental effect upon the



Tendipedidae population of a northern Colorado lake.  Living larvae were



absent three days after treatment and repopulation was not complete until



nine months later.  The Oligochaetes exhibited no adverse effects from the



toxaphene.  Rotenone had little adverse effect when applied at 1 p.p.m.



(U3).  A very good summary of the pesticides, their use and toxicity to



wildlife, has been prepared by Rudd and Genelly (16U).

                         Putrescible Wastes





Effects of Organic Enrichment




       A Field study of two stream sections, one in its natural state



and the other enriched by the sewage from a town of 500 people, showed



that trout grew much faster, were in better condition, and the bottom



fauna was more abundant in the enriched section (U9)»  Physical, chemical,



and biological surveys of the Sone River which receives wastes from kraft



pulp mills, a sugar factory, and cement factory, show that the involved



portion of -the stream may be divided into five zones according to the



degree of pollution.  Toxic constituents of the pulp mill are well



diluted even during the low flow period but the high organic content of



the wastes reduce the D.O. to near zero and change water quality and



bottom conditions for 15 miles, adversely affecting the fish and inverte-



brate habitat (138).



       The production of oysters in the United States has declined to



half its former volume.  Domestic and industrial wastes affect the oyster



bottoms by:  direct poisoning of shellfish) smothering of shellfish



grounds by sludge; and rendering the water unsuitable for harvesting



shellfish because of the high bacteria content.  Siltation has covered

-------
                                -27-





covered many beds.  Sulfite mill wastes encourage the diatom Melosira,



which increases to the point where the oysters are smothered under a



thick blanket of diatoms.  Overfertilization by duck farm wastes produced



a similar problem (?8).  In Britain many formerly productive oyster beds



have either been abandoned or have declined in value as domestic and



industrial pollution has increased (35).  A study of the process of



pollution and self-purification in oysters and mussels indicated that



when the water temperature is above 10° G. both pollution and cleansing



take place rapidly as the quality of the water overlying the bed alters



and that both types of shellfish may become highly polluted..  When the



temperature of the water is about 1° to 2° C. mussels continue to show



this same pattern of pollution and cleansing but oysters may not become



polluted (210).



       It is pointed out that suspended matter may represent a greater



pollution danger than liquid effluents.  The deposition of sludge on the



stream bottom has many biological effects and is of outstanding importance



(192).  Fertilization can have very marked effects on plankton production



and general productivity, transparency, and pH (li;2).  Investigations of



the area around three sewage outfalls in southern California indicated



discoloration of the water and increased plankton growths (1?8).



Investigation of a number of small ponds showed that the-addition of



sewage increased Daphnia populations (191).  Experiments on eutro-



phication in mixtures of river water and effluents showed that algae



titre is affected by numerous factors and can be used as a criterion of

-------
                                -28-





tlie degree of eutrophication of water and mud (22).



Indicators of Organic Enrichment



       The intestines of fishes caught off shore in the Mediterranean



are free of entero-bacteria whereas in those caught in the littoral



zone there is an intestinal flora similar to that in man or the warm



blooded animals.  Laboratory studies have shown that the investigation of



the entero-bacteria and enterophages in fishes can give information as to



the pollution of the waters in which the animals live (70).  Bottom samples



from Santa Monica Bay, California, indicate six biological zones, each



supporting a characteristic fauna which differs with depth of sea floor,



nature of sediments, and distance from the end of outfall sewers (72).



Bottom fauna studies in the Los Angeles Harbor area in the vicinity of



waste outfalls indicate that the area can be divided into five zones on



the basis of bottom conditions and bottom organisms.  Samples taken in a



line away from the waste outfalls indicate that the number of species of



bottom organisms increased with distance.  Capitella capitata was found



in the zone around outfalls and appears to occupy a position similar to



Tubifex in fresh water (160).  In the Los Angeles Bay area dredging



provided new and clean bottom areas which were then colonized by benthic



organisms.  Within a year conditions deteriorated and oil sludges deposited



on the bottom.  The effects of the removal of contaminated bottom materials



and the progress of contamination thereafter were demonstrated by D.O.,



sulfide, odor, organic carbon content of deposits, and the makeup of



benthic populations (159).

-------
                                -29-





       Weimann believes that organisms serve as indicators of different



degrees of organic enrichment or pollution and that the  flora and  fauna



can give more information than chemical and bacteriological examination



(202).  From a bacteriological point of view the coliform group is



currently considered the best available indicator for use in the esti-



mation of pollution of waters and in the sanitary evaluation of pure



waters of potable quality.  Only when the count exceeds  a normally



expected minimum number of coliform organisms is pollution indicated (92).



Fungi which are very common in association with decaying organic matter



cannot be used as indicators of pollution because of their ubiquity



throughout nature.  Pollution tolerances occur but must  be evaluated care-



fully in regard to individual species.  A negative approach can be used



wherein larger numbers of colonies of small numbers of species can be iso-



lated from samples obtained in the more polluted portions of a single



stream (38).



       Results of river surveys have shown diatoms to be easy to collect



and study and good indicators of river conditions.  It is believed that



similar relations hold for estuaries, bays, and ship canals as for fresh



water rivers (15>1).  From many studies that have been made it is believed



that diatoms can be used as a group to indicate the ability of a water to



support aquatic life.  From variation in the nunber of species and



individuals of each species, curves are developed which  when compared may



reveal waters adversely affected by pollution, mildly affected, severely



affected, or not affected

-------
                                -30-





       In Florida the indicator organism program is based on organisms



which are indicative of the absence of organic pollution rather than on



its presence (18).  Number of species present and the abundance of



individuals appear to be a criterion of pollution in lakes as well as in



streams,  In enriched areas the following forms were the most abundant:



Tubificid worms, Procladius midges, Tendipes plumosus, and Tendipes tentans,



Under conditions of severe pollution with organic wastes only Ihe



Tubificidae were able to survive (183).  The genera of algae occurring most



frequently in enriched waters are Oscillatoria, Euglena, Navicula,



Chlorella, and Chlamydomonas^  The five most abundant species are



Nitzschia palea, Oscillatoria limosa, 0. tenuis, and Arthrospira jenneri



(llj.8).  Immediate sewage pollution of a stream, resulting in oxygen



depletion, tends to eliminate all but a few species of anaerobic ciliates



and colorless flagellates.  Certain species of algae and protozoa are



readily associated with sewage wastes but investigators should distinguish



between "characteristic of" and "indicative of" organic enrichment (105>).



Certain mollusks, as the Unionidae, are not associated with near septic



water resulting from organic enrichment.  Such forms have an index value



in that their presence typically indicates good D.O. and attendant physical



and chemical conditions associated with clean water, and they may be



called index organisms of clean water (89).  Studies in the River Mora vice



indicated that several species of Trichoptera were indicative of pure water



conditions.  Among these are Pojycentropus flavomaculatus, Notidobia



ciliaris, Rhyacophila septentrionis, Glossosoma boltoni, and several

-------
                                -31-





others (116).  In order to utilize macro-invertebrates as indicators of



environmental conditions in streams it is essential to have a knowldege



of the composition of the population and the abundance of the different



organisms under the various environmental conditions which prevail in



clean and organically enriched waters.  Clean waters are usually charac-



terized by a great variety of invertebrates, consisting of herbivores,



carnivores, and omnivores, lung, tracheal tube, and gill breathers.



In general a population containing numerous gill breathing forms as may-



flies, stoneflies, and caddis flies, is indicative of clean water and their



absence denotes a superabundance of organic materials and/or low. D.O.



By contrast associations engaged in the utilization of excess organic



materials are characterized by few species but large numbers of individuals,



The macro-invertebrates most characteristic of septic zones are those which



can exist under conditions of low oxygen or have adaptations for breathing



atmospheric oxygen (63).  The terms pollution and biological indicators



are often loosely used.  Biological indicators are generally indicators



of organic enrichment.  Pollution means damage to a beneficial use.



Changes in an aquatic fauna do not necessarily mean there has been damage.



It is believed that a more definite relationship must be shown between



changes in the biota and damage to beneficial use before certain organisms



can be referred to as pollution indicators.  A study of the fish popu-



lation and the fish catch gives the best information on how wastes are



affecting sport or commercial fishing (U7).

       An explosive epidemic (1?£) of infections hepatitis in Delhi,

India was attributed to municipal drinking water, and showed that the virus

was not inactivated by the treatment methods used.  This incident indi-

cated that contamination of the drinking water supplies by sewage should

be avoided, if at all possible.

       Richter (162) has reported the presence of at least 8 species of

Salmonella present at various times in channel water in Buxtehude Rasch,

Germany.  He noted the increasing occurrence of the Salmonella group in

western Europe as a result of intercontinental travel.  Stoll (179) re-

viewed the legal provisions of the German Democratic Republic in an

attempt to prevent human infection through polluted waters from slaughter

houses.  The conditions under which Salmonella can live and grow in water,

such as presence of protein materials, effect of salinity, influence of

movement and stagnation were discussed by Steiniger (177).  He concluded

that the degree of pollution, oxygen demand, and coli content are not

suitable methods of determining the presence of infectious agents; more

Salmonella may be present in apparently clean water than in a polluted

water.  Greenberg, Wickenden and Lee (69) have successfully identified an

S. typhi carrier in a town of 2200 by application of the swab procedure
                                              ~4
developed by Moore, in which gauze swabs were suspended in sewage at

various points through the sewer system and followed back through house

connections into the toilets.  A new procedure for the more rapid isolation

of Salmonella from polluted water was described by Kenner, Rockwood and



Kabler (99)»  The technique combined the use of a selective medium,



selenite brilliant green, with membrane filter culture.



       Gol'dfarb (67) demonstrated dysentery bacilli in low concentration



in water by the phage titre increase reaction.  In experimentally infected



well water, bacteria were detected in lower concentration and over longer



periods of time than in tap or river water.  Kenner and Kabler (98)



isolated five strains of Mlmeae from Ohio River water.  All previous



isolations of these organisms have been made directly from specimens of



human origin,  Greenberg and Kupka (68) have reviewed "Tuberculosis



Transmission by Waste Water".  Hospitals treating tuberculosis patients,



as well as dairies and slaughter houses handling tuberculous animals may



be expected to discharge tubercle bacilli in their wastes.  Conventional



sewage treatment is inadequate to significantly reduce the nunber of



tubercle bacilli in the sewage.  In order to provide adequate disinfection,



complete treatment plus chlorination with 20 p.p.m. for at least 2 hours



contact time is necessary.  Cooke and Kabter (lj.0) and Cooke and Busch (39)



found sewage polluted waters to be rich in certain strains of "plant



disease fungi" and cellulose-decomposing fungi which have become acclimated



to living in aqueous habitats, and which were able to use dissolved



oxygen in competition with other sewage organisms for reduction of organic



materials.  During the treatment of sewage and wastes these fungi were



active in purifying sewage in which they were living.



       Dauer and Sylvester (i4i) in their "1956 Summary of Disease Outbreaks"

-------
                                 -35-





 included nine water-borne  outbreaks in which 1,719 persons were affected.



 Two large and two  small outbreaks were from contaminated public water



 supplies, one of 800  cases was due to Shigella flexneri.  One outbreak of



 typhoid  fever, 27  cases, was attributed to contaminated well water.



 One outbreak of infectious hepatitis of 276 cases was considered water-



 borne and E. coli  was isolated from the supply.



       Hendriksen  (78)  has extended his studies on coliform tests of



 water carried out  in mannitol broth at 30°C. followed by subcultures in



 lactose broth at 39°C.  The rate of coliform detection was higher by the



 new method and seemed to give more reliable results than tests in lactose



broth at  37°C.  Karakasevic (9k) made a comparative study of culture media



 for  the enumeration of  coliform bacteria, and recommended that the technique



 now in use in Yugoslavia be replaced by "Standard Methods" (U.S.).  In his



 study of  the effect of  storage temperature on toe survival of coliform



 organisms in water, McCarthy (127) found that water samples with relatively



low  coliform densities  (23 or less) which had been in shipment up to



 2l| hours at any reasonable temperature yielded results which statistically



 correlated very well with the degree of pollution existing at the  sampling



point at the time of collection.   Samplss with higher initial coliform



densities, 230 or more,  were more likely to  exhibit decreases in coliform



content during  2h hours  storage.   Njoku-Obi  and Skinner (1140 consistently



obtained lower counts of coliforms and Escherichia species in boric acid



lactose broth at U3°C. than when  standard lactose broth was used at 3S>°C.



They concluded that boric acid  lactose broth  cannot be depended upon to

-------
                                -36-





detect fecal coliforms, although they did not clearly define their



criteria for differentiating Escherichia, Aerobacter and intermediate



forms.



       Sullivan, Hartley and Slanetz (182) reported that the enterococci



occur in the feces of man and certain animals and in polluted water or



sewage in as great or even greater numbers than do the coliforra bacteria,



and that in some instances it may be possible to distinguish between



human and animal contamination of water based on the types of enterococci



present in the samples.  In the examination of 1000 water samples in



Argentina, Leiguarda et al (113) demonstrated contamination in 332,



83.1$ contained coliforms and U5.8$ contained streptococci.  Because



16.9$ of the contaminated samples contained streptococci only, they



considered the possibility of adding tests for streptococci to the other



methods used in the bacteriological examination of water.



       Reitler and Seligmann (161) showed that Pseudomonas aeruginosa and



E^ coli can coexist in pure water, but in mixed cultures%in peptone water



Ps. aeruginosa can inhibit E. coli.  Water supplies containing many



Ps. aeruginosa but few or no coli-aerogenes bacteria were found to be



relatively common in northern Israel and in view of Ps. aeruginosa'a fecal



origin and its potential pathogenicity, it was concluded that this



organism should be considered as well as the coli-aerogenes bacteria in



assessing the suitability of water for drinking purposes.  Due to the high



concentration of cytochrome oxidase within the cells of Ps. aeruginosa a



practical differential test has been developed (5>7) based on the  formation

                                 -37-





 of indophenol blue  from the  oxidation of  P-aminodiraethylaniline oxalate



 in the  presence  of  alpha naphthol.   This  test suggests the possibility



 of a  procedure for  the  selective enumeration of Pseudomonas in polluted



 water,



        Collin and Kipling (36) have  devised a new technique for the



 enumeration of water-borne bacteria by a  "direct count method".  Results



 by the  direct count were from six times to 11,000 times greater than by



 the colony  count.  Fournelle (5>U) described a procedure for determining the



 potability  of water supplies in the field, which is said to be adaptable



 to special  areas for removal from a  laboratory.  Fournelle and Page (£5)



 found the dye  uranin and Streptococcus zymogenes to be satisfactory



 indicator agents to determine the direction and rate of travel through



 ground  waters.  Robson  (163) added Serratia indica to sewage to determine



 the distribution of effluent material discharged into the sea.



        Willis  (206) showed that black  colonies 3 mm. or more in diameter,



 which developed on Wilson and Blair's medium inoculated with untreated water



 from a  city's supply, signified the presence of Clostridia, usually Cl.



welchii..  He  (205) also  found anaerobic bacilli in the sand from .the filter-



beds of a city water supply, and thought it probable that these organisms



were being added to the water as it passed through because anaerobes were



present in the treated water.  It was pointed out that the anaerobe test



 on treated waters was useful in assessing filter efficiency.



       Friberg and Hammarstrom (56) studied "the effect of free available



chlorine on bacteria and bacterial viruses".   At pH 7.2 and temperature <

                                -38-






of 6° C., exposure for 1 minute to a concentration of 0.025 to 0.05 mg/L



chlorine effected a thousandfold reduction of typhoid bacilli, S. sonnei



and coliform bacteria, but concentrations of 0.10 to 0.15 mg/L chlorine



were necessary to effect the same reduction in numbers of Sal, typhimurium,



Strep, faecalis and Staph. aureus.  The coliform, sonnei and typhimurium



phages were reduced a thousandfold by concentrations of O.OU to 0.0? mg/L



free chlorine.  Kelly and Sanderson (97) pointed out that chlorine residuals



found to be sufficient for bacterial disinfection were not similarly



effective as viral disinfectants, and that inactivation of Poliovirus by



chlorine may follow a course not strictly linear.  Watkins, Hays and



Elliker (201) made a comparison under laboratory conditions of the relative



effectiveness of representative hypochlorite, quaternary and iodophor



germicides- in the destruction of Strep, cremoris phage.  The results



suggested that an active hypochlorite preparation should provide the most



effective sanitizing procedure for control of bacteriophage in dairy plants.



Fetner and Ingols (52) determined the lethal concentration of ozone for



E. coll suspensions at 1° C. to be O.U to 0.5 mg/L.  Ladendorf and Ladendorf



(106) have made similar observations on the efficiency of chlorine dioxide



for disinfecting water.



       Lowe and Lindsten (120) have summarized the removal of GBR contami-



nants from water.  Lewisite and nitrogen mustard can be effectively re-



moved by treatment with activated carbon followed by good coagulation and



filtrationj GA and GB were reduced by treatment with soda ash plus coagu-



lation and filtration.  Sal, typhi, Coxiella burnette and Botulinum toxin

                                -39-





were removed by coagulation, filtration and chlorination to 20 minute



residuals of 0.35 to 0.75 p.p.m.

(168), Adams in Pennsylvania (1), and Gohar and Eissa in Germany (66)

in the bacteriological examination of water.  They have pointed out certain



advantages of the method and have also listed limitations.  These ad-



vantages and limitations have been discussed by Clark, Kabler and



Geldreich (32).  Felsenfeld and Rokkaku (51) have adapted the membrane



filter technique to the recovery of Vibrio comma from water supplies and



Papavassilion and Wegner (ll$) have used the technique for the detection of



sulfite-reducing Glostridia (01. perfringens) in water and other liquids.



       Levin, Harrison and Hess (115) Have published further observations



on the use of radioactive culture media in the enumeration of coliform



organisms in water.  pH exerts a pronounced biological and chemical effect



on the test.  When the broth is alkaline, much of the carbon dioxide



remains in solution in the form of the bicarbonate ion,, The nonmetabolic



evolution of G^k)2 from the sterile 1-C^ lactose is the chief immediate



problem demanding attention in the development of the test.

       Heukelekian (80) assembled a notable symposium in which it was



sought to present a review of the basic microbiological processes related



to purification of polluted waters.  While many of the papers may be noted



elsewhere, the assembled symposium is deserving of attention.  It includes



discussions by Wyss on "Microbial Adaptation" j Weindling on "Microbial



Associations and Antagonisms"j Nickerson on "Transformations of Carbon



Compounds"; Delwicke on "Biological Transformations of Nitrogen Compounds";



Starkey on "Transformations of Sulfur by Microorganisms"; Barker on



"Biological Formations of Methane"; Davis on "Microbial Decomposition of



Hydrocarbons"; and Krauss on "Photosynthesis in the Algae".  Each article



is discussed by one or more authorities.



       The direct chemical characterization of organic water pollutants has



found continued application and study.  Middleton and Rosen (135) review



technique and discuss trends in organic industrial pollution which make



specific chemical characterization of pollution a matter of growing im-



portance.  Holluta and coworkers (82)(83) have also presented the details of



techniques generally aimed at the recovery and characterization of organic



materials in surface water and water taken from infiltration galleries.



       In a paper which was overlooked in the 1956 review, Sawyer (166)



and his students reported on the interrelationship of rates of biological



assimilation and. chemical structure of synthetic detergent materials.



An additional report considering the effect of commercial synthetic



detergent ingredients on water and waste quality was presented by Sawyer

       Hexadecanol (Cetyl Alcohol) has been investigated as a water



pollutant because of interest in the material as a possible suppressor



of evaporation.  Lay cock (10?) commented on the effect of the material



on aquatic life.  Ludzack and Ettinger (121) report laboratory studies



of the biological destruction of hexadecanol and point out that the



material undergoes biological destruction under laboratory conditions



which simulate proposed use conditions.



       Other studies of the biological stability of various materials



appeared.  Hatfield (?U) studied the biological stability of 23 compounds



produced by petrochemical processes, using activated sludge cultures



acclimated to the chemical for periods of a month.  Ludzack and Kinkead



(123) made laboratory studies of the oxidation of hydrocarbons derived



from motor oil by microorganisms.  They also presented analytical



evidence of the formation of intermediate oxidation products.



       Mils and Stack (136) emphasized the importance of using acclimated



seeds when attempting to estimate the B.O.D. load caused by an industrial



waste,



       In an interesting application, Christenson, et al., (31) proposed



the use of activated sludge using nitrate ion as an oxidant source,



methyl alcohol as organic feed, in a system where removal of nitrate from



a waste was sought.

              OXYGEN SAG AND STREAM SELF-PURIFICATION

       In the third of a series of reports on comprehensive studies of
the character and stream self-purification characteristics of Wisconsin
rivers, Lueck et al (12lt) have presented analysis by several devices
of the stream self-purification capacities of the Fox and other Wisconsin
rivers.  They have suggested that the self-purification capacity of streams
may be compared on the basis of pounds per day of ultimate BOD satisfied
per 1,000 cfs per mile, or on the basis of the time required to oxidize
90/6 of the ultimate BOD taken together with the deoxygenaticn velocity
constant ki, or on the basis of pounds per day of 5-day BOD per cfs per
part per million of D.O. removed.  The capacity of the Lower Fox River
at various seasons and in several reaches is compared on the above basesf
This report represents a considerable amount of work, and some most
interesting data is presented.
       On the basis of the third of the above noted units for comparison,
namely, pounds of 5-day BOD per day per cfs per part per million of D.O.
removed, the authors conclude that "at low temperatures, when the stream
purification proceeds at a slower rate, considerably higher loadings can
be supplied to the stream without adversely affecting downstream con-
ditions."  And at a later point "it is evident from previous discussion
that the lower the purification rate, or k^ factor, the greater maybe
the load applied to the stream.  Any factor such as limited biological
activity at lower temperatures or characteristics of the waste to be

-------
                                -US-





oxidized which tend to decrease purification rate, will improve



purification capacity and make possible the satisfaction of higher



loadings."



       This concept is rather unusual in that it might imply, for



example, that unlimited loads could be placed upon a stream in the



event k-^ were reduced to zero - by the presence of sufficient amounts of



toxic materials, for example.  The 5-day BOD is, of course, affected by



the course of reaction, or k^, while the ultimate BOD, at least in



principle, should not be thus affected.  It is therefore difficult to     .



understand why the authors chose to use the 5-day BOD in this case for



the purpose of interpreting self-purification capacity in terms of k^



It would be interesting to compare the stated stream self-purification



capacities on the basis of ultimate rather than 5-day BODs.  Conceptually,



if the entire river is considered rather than a restricted reach, the



entire pollution load introduced at any point must eventually be satisfied,



and the critical point of the oxygen sag curve may or may not occur within



this restricted reach, depending upon the specific circumstances involved.



It is agreed that somewhat higher loadings may be tolerated at lower



temperatures, but the primary reason for this is  the increase, in oxygen



saturation values, rather than the reduction of kj_.          ;



       The above paper also presents very  interesting implications of the>,,



effects on .self-purification  capacity •,of large concentrations of algae.



       Hills and Stack (136)  have presented an interesting discussion of



the effects of  acclimation of seed on the  course- of the BOD reaction in

-------
                                -U6-






the case of four pure petrochemicals.  The £-day BODs of the petro-



chemicals are compared using both unacclimated and acclimated seeds.



The organic chemicals used were acrylonitrile, ethylene glycol, carbitol,



and acetone.  Only the acetone yielded classical BOD behavior without



acclimation of the seed.  In the other cases, the use of acclimated seed



resulted in higher BOD values, more closely approximating the oxygen



demands actually exerted in a stream.  The authors suggest that, to



evaluate the effects of other organic chemicals on stream self-purification



capacity, the ultimate BOD should be determined by the use of acclimated



seed organisms.



       That the potential pollutional effects of organic materials are



a function not only of their BOD as usually measured, but also of their



persistence and relatively slow oxidation, has been indicated by



Ettinger (5>0).  It is indicated in this paper that the theoretical oxygen



demand maybe distributed at any time as:  material oxidized to carbon



dioxide, unoxidized readily available food, cell material, and unoxidized



exotic food.  The actual distribution among these four phases will, of



course, be dependent upon the characteristics of the material involved.



Selected examples are taken from the literature to demonstrate the effect



of acclimation of seeds on organic materials previously looked upon as



essentially unoxidizable.



       Nickerson (1U3) has presented metabolic maps of various hydro-



carbons, oxygenated compounds, and amino acids as a basis for the under-



standing of sewage treatment and stream self-purification mechanisms.

Leclerc et al (108) have provided an example of the determination of



self-purification capacity of a river for the purpose of obtaining water



of sufficient purity for the food industry.  Pillai et al (15>3) present



an intensive reivew of the literature on the subject of stream self-



purification capacity, together with information regarding self-purification



of untreated sewage from Bangalore, India, in a series of open channels.



Muller (139) also presents a general review of -the factors involved in



stream self-purification, notes the inadequacy of even complete biological



treatment in densely populated regions, and discusses possible methods of



increasing the stream self-purification capacity.



       Rand (l£6) has presented an excellent critical review of toe



available literature on theoretical aspects of the reaeration factor.



In doing so, he has traced the development of theoretical concepts on this



subject from their beginnings through the most recent work, including that



of O'Connor and Dobbins (1U6).  The article provides an excellent review of



the available material and correlates the various  concepts involved.



It is recognized that the work of  O'Connor and Dobbins makes possible for



the first time predictions of k2 independent of observed data.- Rand



indicates that the effects of turbulence on the reaeration velocity



constant are only now beginning to be understood,  and that much further



work remains on this phase of the  problem.  The evidence that he has



accumulated indicates that the effects of temperature on the reaeration



constant are adequately known, but that the effects of various pollutants



including ordinary sewage, as well as detergents,  insofar as such

-------
                                -US-






pollutants affect reaeration, are not well known as yet.  In another



discussion on this subject Rand (1^7) presents the results of some of his



own experiments on reaeration.  Upon examination of various factors >hich



might affect the reaeration rate, he indicates that the BOD correlates



best with the observed reaeration rates.  Both quiescent and agitated



systems were investigated with the same relative effects observed.



       Gameson (60) has presented the results of a study of reaeration



occurring as the result of water passing over weirs in rivers.  He re-



ports that the oxygen content of the water may be increased as much as



£0 percent of saturation, and an empirical equation to represent these



effects is presented.  The effects of various types of weirs are dis-



cussed.  Wagner (197) describes the use of turbines of water power works



for the purpose of oxygenating canalized streams.  He discusses experi-



ments carried out on the River Brenz, the air requirements,  and the effects



of various design features of the turbines.



       The subject of estuarine pollution is receiving considerably more



attention in the recent literature.  Kaplovsky (93) has described his



investigations of pollution of the Delaware River,  using the "same-slack"



sampling technique, and his results are most interesting.  The "same-



slack" method consists of taking from one to three surface water samples



in the ship channel at each sampling station just at the time that the



tide begins to turn.  In other terms, a sampling run is made in which the



samples are collected at all stations at the slack of the same tide.



That such surface samples are representative of the ship channel water

-------
                                -U9-





is demonstrated.  Kaplovsky concluded that this method of sampling,



provided results more valid than those obtained by cross-sectional



sampling.  His data indicate that the "same-slack "method eliminates much



of the effect of tidal periods and the results are therefore more easily



interpretable.  He also indicates that has studies of the Lower Delaware



River indicate no appreciable deviation from the usual picture of self-



purification of inland streams, and the data regarding the nitrogen



balance is especially interesting in this regard.



       Burt and Marriage (2?) have presented a theoretical analysis of the



distribution of pollution in the laquina River in Oregon on the basis of



Storamel's (180) equations.  The study involved wastes from a proposed



pulp mill on the Yaquina River, and five possible outfall locations were



investigated analytically.  The computations indicated that the,/pollution



concentration near any outfall, as well as the concentration: upstream: from



the outfall, would decrease rapidly as the outfall was moved toward the



ocean.i  However, concentrations at any given point downstream from two -or



more outfalls were found to be esential]y independent of the position of



the outfalls.  Following these analytical studies, it was decided to-pump



the pulp mill waste directly to the ocean and to thereby avoid significant



pollution of - the Yaquina River.



       An analysis of factors affecting the oxygen balance in Ihe



River Thames Estuary has been presented by Gameson and Freddy (59).



The data include  dissolved oxygen observations in the estuary over a



period of several years.  The various sources of pollution have been

-------
                                -50-
considered and a theory of mixing outlined on the basis of which the



distribution of oxidizable material from different groupings of waste



discharges has been computed.  The oxygen balance of the entire estuary



was then examined and an average rate of solution of oxygen from the



atmosphere estimated.  The oxygen balance having been thus estimated, the



theory has been checked against a variety of observed conditions in the



estuary and agreement of observed and computed data obtained.  On this



basis, it was then possible to predict oxygen changes most likely to occur



as the result of various alterations of pollution loads and other



controlling factors.



       Ingram (90) has presented a general review of the factors which



affect estuarial capacity for receiving wastes.  The factors considered



include tidal displacement, fresh water flow, tidal flow, wave action,



density currents, vertical and horizontal countercurrents, stratification,



and diurnal and nonperiodic wind effects.  Combinations and complications



of these factors are also discussed.  Mann (130) has also presented a



discussion of the general hydrologic conditions in a tidal river and



illustrated the principles involved by the example of behavior of sewage



from the City of Hairburg discharged into the  River Elbe.  The self-



purification capacity of the tidal stream and effects of polluted tribu-



taries are discussed.

                     STREAM STUDIES AND SURVEYS





       Water resource development and conservation with associated



water pollution control continues to be of prime importance.  Many stream



studies, however,  fail to reach formal publication and therefore are not



reviewed.  A greater effort should be made to encourage publication.



It may be noted this year that several studies of European waters have been



reported.



       Tsivoglou, Harwood and Ingram (189) emphasize the importance of



stream surveys for adequate control of radioactive liquid waste discharges



associated with the rapidly developing private use of radioactive materials*



Excessive radioactive wastes from nuclear reactors, uranium mills, and



radioisotope research laboratories will interfere with other legitimate



stream uses.  There is no stream self-purification capacity for radioactive



wastes as there is for ordinary organic pollutants.  Control is based on



three types of stream samples - water, aquatic biota, and bottom deposits.



       A survey was reported by Schneller (171) of a 25-mile stretch of



Salt Creek, Indiana, to examine the physical and chemical characteristics



of the water during the black-water period which persists during leaf-fall^



and to compare this condition with that during the remainder of the year.



The dissolved oxygen content was shown to decline to a minimum of 0.5 ppm



during the leaf-fall when free carbon dioxide was as high as 20 ppmj



during the remainder of the year the dissolved oxygen and free carbon



dioxide ranged from £-12 ppm and 5-15 ppm respectively.  The effect of



extreme conditions on fish life is discussed, no serious fish mortalities

 normally occur.  Wiley, et al  (20ii)  describe the combined chemical,
 physical and biological studies  on the Lower Fox River, Wisconsin, during
 19?5-5>6  through the cooperative  efforts of State and industry to determine
 sources  of pollution and the self-purification capacity of the stream.
 Combined artificial and natural  pollutants cause critical dissolved
 oxygen conditions below major  sources of wastes especially during hot
 weather.  Detail study of algae  problems will be required to assess more
 accurately the amount of organic matter derived from this source since it
 appeared that algae contributes a substantial portion of organic load
 during warm weather.  Scott, et al (173) discuss the organization of
 cooperative State-industry studies in Wisconsin.  The cooperative approach
 permits  assembly of much more  complete data covering more of the variable
 factors  than would otherwise be available to either industry or government
 acting alone.  Chemical, physical and biological characteristics of a
 30-mile  stretch of the Ottawa River below an oil refinery near Lima, Ohio
 was presented by Ludzack, Ingram and Ettinger (122).  Evidence indicates
 that oil was not biologically assimilated but stored as oily sludge on the
 river bottom and flushed by periodic river rises.  Accumulated sludges,
 as these, are believed to be responsible for extreme impairment of water
 quality which sometimes occur when a river is flushed out following a long
 period of low flow.
       The effects of polluted waters of the Flon on Lake Geneva at Vidy
were studied by Konod (137).  It vas concluded that the chemical composition

-------
                                -5U-





of the lake water was not altered by the Flon but that turbidity and the



quantity of micro-organisms were increased greatly.  Noisette (llii?)



conducted surveys on a continuing basis of the mineral content of the



rivers in France.  The source of minerals was geological, urban and rural



sewage, and industrial wastes.  The conclusions were that the sources of



salts are constant, variation in mineral content of the rivers depending



on rainfall and flow.  The degree of variation requires precaution by



industrial users; geologic factors acting alone can cause high minerali-



zation.



       Leclerc, Beaujean and Heuse (110) studied the pollution and self-



purification of the Geer River.  They indicate that the principle observa-



tions guiding such a study should be based on temperature, time and



turbulence.  Particular attention should be paid to gradient, flow and



temperature.  Leclerc and Beeckmans (109) describe a series of studies on



the Sambre River.  Data were gathered on flow, temperature, pH, settieable



and suspended solids, dissolved oxygen, £-day B.O.D., sulfates, iron,



chlorine and toxicity.  The stream was found to be very polluted.  LeStrat



(llU) observes that difficulties in sewage treatment attributed in the



United States to detergents have not been experienced in France because,



except in a few large cities, laundry water is dispersed to the ground via



gutters.  As a check on detergents, surface tension determinations are



made constantly on the Seine, Marne and Olse rivers and on the Chicky



interceptor sewer.  While the value for pure water is 7l*-75> dynes, the



rivers run to 70 dynes and the sewer is below 65, sometimes down to

-------
                                -55-

58 dynes.
       An article based on the  work of Kalweit and  Brandt  (10)  indicates
that hardly a river in Central  Germany reaches a scale  of  water quality
satisfactory for bathing purposesj  ground water is  being utilized to  a
greater extent by industry and  municipalities due to this  condition.
Further it is shown that damage to fisheries on the streams of  the'German
Republic can be caused by removal of oxygen, sewage fungus, presence  of
metal salts from mining and metal industries, sand, clay,  kaolin, coal
dust, and cyanide and phenol from chemical industries.   Fijiwara et al
(53) state that the river Yukawa, Japan, contains sulfuric acid derived
from sulphur deposits in the Yatsugatake volcanoes  districts.   The add
is considerably neutralized when the Yuhawa River joins the Ghihuma which
is used for irrigation and fishing.  If the sulphur deposits are mined, it
is believed that the increased concentration :of' add will damage the  use of
water.
       A summary (7) of a paper by Harwood and Wilson presents  an
investigation, including a model study, which considered disposal of  up -to
500,000 tons per year of power station ash by cooling water conveyance for
disposal by seaj barging to sea was the alternate.   Eighty percent of the
ash would be borne away to sea in the cooling water stream and  in calm
weather be deposited beyond the outfall.  When waves are 2 ft.  and upwards,
this deposit would be broken up and moved out to sea.  Experiments in
the wave channel pointed to the material being distributed at depths  as
great as I|0 fathoms and probably more, with likely dispersal over a wide

-------
                                -56-





area of the North Sea.  Shapiro (17k) reported on pollution survey



sampling of N. Y. Harbor.  The first problem dealt with the extent



New York Harbor and adjacent waters were actually polluted and the



second problem was concerned with the tidal and current distribution of



the polluting load.  Extensive pollutional and hydraulic surveys were



necessary to ascertain details of the problem and background for



corrective measures.



       The good and bad features resulting downstream from water storage



for hydraulic power generation is discussed by Ingols (88).  On the  good



side, water below a dam contains less sediment, color,  bacteria, and has



a lower temperature.  The bad features, oftentinss not fully appreciated,



are that directly below the dam, water may be devoid of oxygen during



the summer when water quality is critical, and may contain manganese or



sulphide.  Furthermore, flow pattern of power generation may permit



slime development on the bottom during low flow and scouring off of  slime



during high flcwj wastes may be stored in tributaries during high river



stages and discharged to the river during falling river stages, and, a



city may discharge its heaviest sewage load during minimum river stage if



located 12 or 36 hour flow time downstream from the dam.

       Vinogradov (19U) reports that the Sanitary Authority of the

U.S.S.R. regulates the concentrations of certain substances in waste

waters discharged to streams.  These include:

       In Austria Liepolt (118) concludes that the primary importance of

hygienic considerations justifies the general aim of restoring all

Austrian surface waters to their natural condition.  He suggests that the

Jiinimum standard should be the maintenance of beta mesosaprobic conditions

at all times.  This biological classification, proposed by Kolkwitz and

Marsson, describes the zone of stream recovery, following severe pollution

in which mineralization is approached, blue-green algae, diatoms and varied

animal forms occur, and dissolved oxygen nears saturation.
       The Olio River Valley Water Sanitation Commissicn staff (6) has
proposed a plan for controlling chloride pollution of the river.
The average monthly chloride concentration on the main river should not
exceed 125 ppm, based on the most probable minimum monthly-average 10
year flow, and the maximum concentration should never exceed 250 ppm.
The commission's primary concern in selecting chloride limits was pre-
vention of corrosion of metal structures rather than protection of health.
The low limit needed to prevent corrosion assures chloride concentrations
below those acceptable in public water supplies.  Alternate schemes for
computing allowable discharges of chloride wastes from individual sources
are described.

                      EFFECTS ON WATER SUPPLIES





        Kazuaki (96) attributes an outbreak of acute intestinal disease



 to contamination of a water supply by wastes from a sweet  potato starch



 factory.



        Zimmerman (211) reports on an incident of contamination of the



 Trier (Germany) water supply due to explosion of a  kerosene tank which



 released terosene to a tributary of the  Moselle  above the town.  He also



 discusses the  problems of both surface and undergound pollution by motor



 fuels and precautions in choosing  sites  for  and  constructing storage



 tanks for such fuels.  The  California  State Water Pollution Control Board



 (11)  has  published  a report  on an extensive  literature survey  on the



 effects of oily substances  on beneficial uses of water.  Garrett (62)



 discusses  the  problem of possible toxic effects of various chemical



 pollutants in  industrial wastes.



       A report on the continuing struggle to protect the London (England)



water supply against pollution was made (9).  The problem of protecting



water supplies against radioactive contamination resulting from nuclear



reactor operations was discussed at the Nuclear Congress  (13).

                       ABATEMENT AND CONTROL





       The completion of the last link in the $80 million sewage



collection and treatment system in Philadelphia is reported on by



Baxter (16).  Some 66 miles of collecting and intercepting sewers plus



three sewage treatment plants have been financed by sewer service charges



since 19l;6.  Plans are underway between Philadelphia and neighboring



communities to bring sewage from outlying areas to the Philadelphia



plants.  When these arrangements are completed practically all raw



sewage will have been eliminated from the Schuykill and Delaware Rivers



in the Philadelphia area.



       Spies (176) reports on the progress in the stream pollution control



in Oregon.  Since the initiation of the State program in 1938 an estimated



$50 million have been expended by municipalities, industries, and others



for pollution abatement.  During this period the State's population has



increased more than $0 percent, however, the population equivalent of



municipal sewage discharged without treatment has decreased from U£0,000



in 1938 to 60,000 in 19£6.  In 1938 less than 1 percent of the industrial



wastes was being treated while in 19£6 over 78 percent received treatment,



despite a 67 percent increase in population equivalent of industrial



wastes during this period.  Much additional work is required, however, to



protect Oregon's waters.  It is estimated that 100 communities require new



or improved facilities which will cost at least as much as has been spent



since the inauguration of the program, and several existing industries

-------
                                 -61-





 will likewise require new or improved treatment facilities.



        Cleary (33)  in reviewing the  progress being  made to clean  up



 the  Ohio River points out that  when  the  Ohio River  Valley Water Sanitation



 Commission was established in 19li8 less  than one percent of the popu-



 lation on the  Ohio  River  provided treatment.   In 19^7 facilities  are in



 operation or  under  construction to serve 86 percent of the population.



 Good progress is also being made by  the  industries as evidenced by the



 fact that more than two-thirds  of those  plants discharging effluents into



 the  streams of the  Valley now comply with Commission minimum requirements



 for  pollution control.  Much  more work remains to be done, however.



        McCallum (126)  reports on the first year of operation of the



 Construction  Grants  program under Public Law 660.  This section of -the



 Federal Water  Pollution Control Act  authorizing construction grants has



 been the  subject of much  controversy as  to whether or not it would



 stimulate  or retard  sewage  treatment works construction.  Because of the



 time required  for setting up  procedures  for administrative grants program



 no grants  could be offered  until December of 1956.  Reports from  state



water pollution control agencies as well as Contract Awards data  indicate



 that the  construction picture looks encouraging despite the advent of



factors tending to retard construction,  the principal one of which is



the  "tight" money market.



       The Engineering News-Record (112) in evaluating the  first year's



operation  of the Construction Grant Program cites data indicating  that



Federal Grants have stimulated sewage treatment construction.

-------
                                -62-
       The restoration of an important water use as a result of effective



pollution abatement is reported in the case of the Bluepoint Oyster



industry (12) in Moriches Inlet and Great South Bay on Long Island.



Pollution from Long Island duck farms had practically wiped out the oyster



industry.  Abatement proceedings initiated by the State in 195>1 together



with a flush-out of Moriches Inlet by the 195>3 hurricane have combined to



restore this area to favorable environment for the Bluepoint oyster.



       Hoak (81) discusses a rational program for stream pollution control.



He feels there is no direct evidence that stream pollution is a significant



health factor and calls upon state water pollution control agencies to



apply the principle that treatment should be provided only to the extent



that it will adequately protect downstream uses in the receiving water.



He cites the need for the establishment of criteria to better define the



effects of pollution on various water uses and points out that the single



most important factor in pollution abatement is education — as the



benefits of the abatement program are properly explained, funds necessary



to finance construction in order to maintain these benefits will be



f or th coming.



       Wisdom (208) presents an excellent and comprehensive review of



English water pollution law and Lovett (119) points out that the enactment



of legislation alone does not insure abatement of pollution.  A realistic



approach and proper appreciation of the need for a policy of true



conservation of water resources is essential.

        The pollution of surface waters in 18 European countries  is
 discussed by Key (100).  This very excellent summary supplies  information
 on population, industries, water quality, legal and  administrative
 control Measures, waste treatment facilities,  sewage,  and  special national
 and international problems for these several countries.  The story  of  gross
 pollution in Europe  is largely the  story  of industrial areas.  However,
 serious problems resulting from bacterial pollution  from domestic sewage
 are prevalent in small localized areas.   The author  observes that the
 pollution problem may be expected to increase  as the general standard  of
 living  increases and the  final and permanent solution  cannot now be
 foreseen.   The most  difficult pollution control problems appear to be
 associated with the  paper and allied industries.  Other important indus-
 tries are  sugar beet,  dairy products, gas and  coke,  textiles, mining and
 metallurgical.
        In  discussing pollution prevention philosophies and conflicts of
 interest the  author  notes  that several European countries have laws a
 century or more  old  designed  to protect fish from the effects of pollution.
 The author points out that  this may be understandable since the disap-
 pearance of fish is  often the most obvious effect of pollution and needs
 no scientific  test to establish the fact.  The observation is made,
however, that  over-stressing of this point may be in conflict with other
 uses that may be more beneficial to mankind.  The point is made that often
 unrealistic laws have not prevented pollution.  All of these facts point
up the need for better definition of the aims of pollution prevention in

-------
                                -6k-





European countries.  In many instances mistakes of ignorance were made



which now can be rectified only at an enormous expense.  Had present



developments been foreseen definite approaches to protecting the water



resources would no doubt have been applied.  Newly developing countries



should benefit from these unfortunate past experiences.



       Tsivoglou and Towne (190) call attention to the need for state



water pollution control agencies to assume increased responsibilities in



the control of radioactive discharges to surface waters.  The desirability



of basin-wide planning in establishing control measures is emphasized.
