                              Introduction







A.  Purpose:




     The Water Quality Study was initiated to determine existing




conditions of the Codorus Creek Watershed necessary to establish a




Wastewater Management Plan.  The Susquehanna ^iver Basin Coordinating




Committee, in their June, 1970 report, recommended regional sewerage




studies be conducted.




     A high priority was given to six sub-basin areas, the Codorus




Creek being one of these areas,  The Coordinating Committee consisted




of federal and state officials having -jurisdiction within the basin.




The Baltimore office of the Corps of Engineers obtained funds to




develop a Wastewater Management Plan.  Region III of the Environmental




Protection Agency was requested bv the Corps of Engineers to provide




water quality data for the plan.







B.  Scope;




     The scope of this report is limited to the presentation and inter-




pretation of analytical data relative to the existing water quality of




the Codorus Creek Watershed.







C.  Objectives-




     (1)  Establish a base-line record of water quality for the Codorus




Creek Basin.
                                   -I-

-------
     (2)  Determine characteristics and rates of natural  purification


of the Codorus Creek and its tributaries.


     (3)  Determine patterns of pollution downstream from waste


discharges and effects on water uses and monitoring effects of waste


discharge.


     (4)  Estimate waste assimilation capacities of the Codorus Creek


and its tributaries.


     (5)  Estimate reductions in waste loads necessary to meet water


qualitv requirements




D.  Authority:


     This Study x^as conducted and the report prepared under the pro-


visions of Section 3 of the federal Water Pollution Control Act As


Amended (33 U. S. C. 466 et seq.) which authorizes the Administrator

                                         /
of the United States Environmental Protection Agency to cooperate with


other Federal agencies to make joint investigations for the development


of comprehensive programs for the elimination or reduction of interstate


waters and tributaries thereof and improving the sanitary condition of


surface and underground waters.  The Baltimore District, Corps of


Engineers, by letter dated August 30, 1971, requested this office make


a water quality study of the Codorus Creek Watershed, Tributary of the


Susquehanna River, for the purpose of establishing a Wastewater Manage-


ment Plan.

                         Summary and Conclusions




     An intensive field investigation, including sampling and flow




measurements, and laboratory analysis were conducted to determine the




existing water quality of the Codorus Creek,  The summary for this




study is as follows:




     1.  The Codorus Creek watershed, which is a sub-basin of the




Susquehanna ^iver, has a drainage area of about 294 square miles.




     2.  The waters of the Codorus Basin are classified by Pennsylvania




as:




          (a)  water supply for domestic, industrial, live stock,




wildlife and irrigation purposes;




          (b)  recreational use for warm and cold water fishery and




water contact sports;




          (c)  treated waste assimilation and power.




     3.  There are six municipal wastewater treatment facilities, all




of which have secondary treatment.




     4.  There are forty (40) reported industrial pollution sources of




which the State Environmental Protection Field Office, Lewistown, Pa.,




states twenty-two (22) discharge directly into the Codorus Creek.  The




remaining industrial pollution sources are discharged into municipal




treatment facilities, soil application or to the Codorus Creek.  The




largest volume of wastewater is discharged by the Clatfelter Paper Company,
                                   -4-

-------

-------
     5.  All seven (7) wastewater discharges,  sampled in this survey,




do not comply with the effluent standards established by the Pennsyl-




vania Implementation Plan dated December 20,  1967.




     6.  Concentrations of toxic materials exceeding State water quality




standards were found in the stream.  These toxic materials are of the




type normally found in industrial discharges  and are not naturally




occurring within this area.




     7.  Nutrient concentrations far exceed the levels generally found




to be necessary to stimulate the growth of algae and aquatic weeds thereby




accelerating eutrophication.  Stream discoloration, caused by the effluent




from P. H. Glatfelter Paper Company, has retarded this phenomena by




limiting the light penetration.




     8.  Bacteriological data show high counts of indicator micro-




organisms, indicating the potential presence  of disease-causing




bacteria, suggesting inadequate chlorine applications to treatment




plant effluents, direct discharges from individual homes to the receiving




stream and livestock waste discharges.




     9.  Biological data indicated extremely poor water quality within




the Main and West Branches below Spring Grove.
                                   -5-

-------
     10.  A summary of all the physical, chemical, biological and




bacteriological information indicates the Main and West Branches of




the Codorus Creek- along with the major tributaries of Oil Creek and




Mill Creek are grossly polluted from municipal and industrial waste-




water discharges and agricultural runoffs.

                        Description of Study Area







A. General:




     The Codorus Creek Watershed comprises approximately one-third of




the total area of York County and contains over 60 per cent of the




county's population.  The headwaters and outlet drainage occur within




the confines of York County although the watershed limits extend very




slightly into neighboring Maryland.  Three main tributaries drain the




watershed; The East Branch (drainage area - 54.0 square miles), the




South Branch (drainage area - 117.6 square miles, including the East




Branch'i , and the West Branch (drainage area - 95.4 square miles).  At




a point about four and a half miles due south of the City of York, the




East Branch flows into the South Branch, and approximately three miles




southwest of York, the South and West Branches -join to form the main




stem of Codorus Creek which then flows northeast (through York) for




approximately 5.5 miles where the Mill Creek (approximately 20 square




miles) joins the Codorus Creek which then flows for approximately




9.5 miles where it empties into the Susquehanna River.  At its mouth




the Codorus Creek drains a total of 293.6 square miles of open rolling




country in the Piedmont Plateau Region.  (See Figure T)




     The West Branch rises in the southwestern corner of the watershed ,




flows north to Spring Grove, includes the West Branch, East Branch of
                                -7-

-------
the West Branch-and Oil Creek, and then northeast to its junction with




the South Branch.  Lake Marburg, Lake Lehman, Mill Dam and Lake Pahagaco,




along with the Indian Rock Floor Control Reservoir are the impoundments




in the portion of the watershed.  The area drained is generally open




rolling country with a drainage pattern sloping gently toward the York-




Hanover Vallev from an average headwater elevation of approximately




1000 feet.  The stream grade falls less than 600 feet to its confluence




with the South Branch.  Tributary valleys are relatively narrow




(500-1000 feet maximum) until reaching the main valley where a broad,




flat plain borders the Spring Grove area.  Except for isolated reaches,




a wide flood plain prevails along the West Branch to its "junction with




the South Branch.




     The South Branch drains an area with characteristics similar to




the West Branch.  The total fall of the stream from its headwaters




to the West Branch confluence is less than 600 feet.  Rising in the




mid-southern area of the watershed at an approximate elevation of




1000 feet, the stream flows on a general northerly route having a




relatively narrow flood plain.  The valley floor averages approximately




300-500 feet in width until it reaches the vicinity of the York Water




Company Pumping Station below Brill Hart, where alluvial deposits




have created a plain of 1000-2000 feet in width.




     The East Branch -joins the South Branch  approximately four miles
                                   -8-

-------

-------
above the confluence of the West and South Branches.  The Branch rises




in the southeastern corner of the watershed at an elevation of approxi-




mately 1000 feet and flows in a general direction to the South Branch.




The upper reaches of the stream have slightly steeper gradients, the




total fall being approximately 600 feet in 12 miles.  Expanded Lake




Williams is the only impoundment in this Branch.




      The Main Branch of the Codorus Creek starts at the confluence of




the West and South Branches at an approximate elevation of 400 feet




and flows in a northeasterly direction to the Susquehanna River and




discharges at an elevation of approximately 250 feet.  The main stem




of the Codorus Creek has cut a deep rocky gorge through the westward




extension of the Hellam Hills near its mouth.






B.  Geology:




      The Codorus Creek watershed is located in three geologically




similar areas:




      (1)  The Hanover-York Valley consists of limestone (Cambrian




and Ordovician), dolomites with minor quartzites.  This valley is




geologically complicated, badly faulted and contorted.




      (2)  The Southeastern Upland which consists of schists inter-




layered matabasalts and phylites (Cambrian and probably early Paleozoic),




The Pigeon Hills and Hellam Hills, considered as part of this geological




unit, consists of mainly quartzites (Cambrian), and is badly faulted




and contorted.
                                    -9-

-------

-------
     (3)  Triassic Upland which is in the Codorus Creek watershed area




consists of red shales and sandstone (New Oxford).






C.  Climatology:




     Generally, a humid continental type climate prevails throughout




the Codorus Creek watershed.  A growing season approaching 200 days is




common with long hot summers and sufficient rainfall, thus promoting




the flourishing agricultural industry throughout the region.  The summer




months alone produce 10-13 inches of rainfall, the average annual amount




varying from 36 to 45 inches with the heaviest concentration being along




the Maryland border.  Drier winter months produce 7 to 9 inches of




precipitation of which approximately 30 per cent falls as snow.  The




average annual depth of snowfall in the watershed is 24 inches.




     The mean annual temperature for the area is 54 F.  Winters are



relatively short, 32 F reading occurring 100 days or less per year,




while the long, warm summers produce 90 F temperatures approximately 25



days during the season.




     Mountain ridges west of the area are a major influence protecting




the area from the more severe weather occurring to the west and north




induced by the prevailing westerly winds.

                            Study Methodology






A.  Time Period of Study:




     The study was started on August 18,  1971.   The field work was




completed on November 12, 1971, and all laboratory analysis was com-




pleted December 2, 1971.






B.  Sampling and Analytical Methods:




    All sampling and analyses were performed in accordance with either




Standard Methods for the Examination of Water and Wastewater,  Thirteenth




Edition, or The Environmental Protection Agency Methods for Chemical




Analysis of Water and Wastes (1971 Edition).  The Field Laboratory was




established in the Springettsbury Township Wastewater Treatment Plant,




The Field Laboratory was supplemented by the Environmental Protection




Agency Technical Support Laboratory at Charlottesville, Virginia.






C.  Hydrological Methods:




    Time of travel and stream flow data were obtained by the utilization




of a National Bureau of Standards Calabrated "Pigmy" Flow Meter.




    All wastewater flow measurements were obtained from the wastewater




treatment plant flow meters.

                      Analysis and Interpretation of Data







A.  Water Quality Standards:




    Recommended national water quality criteria were developed by the




National Technical Advisory Committee to the Secretary of the Interior




and was completed April 1, 1968.  A summary of these criteria appear in




Table B.




    Water quality criteria were also developed by the Pennsylvania




Sanitary Water Board specifically for the Codorus Creek.  These criteria




appear in Table C.




    The Pennsylvania Sanitary Water Board also developed an implementation




plan indicating effluent requirements and schedule for compliance.  This




plan appears as Exhibit 1.

Treatment Plant Effluent Criteria;


     Facilities axe expected to be designed to meet the criteria at the
critical periods.  In addition, facilities must be operated at all times
at that level of efficiency needed to meet requirements for thecritical
conditions.  This will result in stream quality higher than the criteria
most of the time.

     Specific;  A minimum of secondary treatment is required for all waste
discharge in this area.

     Secondary treatment is that degree of treatment which, in the opinion
of the Sanitary Water Board, will remove practically all of the suspended
solidsj will remove at least eighty-five (85) percent of the organic pol-
lution load as measured by the biochemical oxygen demand test; will accomp-
lish the removal of oils, greases, acids, alkalis, toxic, putrescible, taste
and odor producing substances, and other substances inimical to the public
interest in the receiving stream; will provide effective disinfection to
control disease producing germs; will provide satisfactory disposal of
sludge; and will produce a final effluent that is suitable for discharge
into the receiving wafers.

     In certain waters of this area, secondary treatment of the present
waste discharges is inadequate now, or will be in the future, if the water
quality criteria recommended in Section VI of this report are to be met.
Tertiary treatment of wastes or other methods of advanced water quality
control will be needed for the following waters of this area:

Exhibit 1
                    IMPLEMENTATION PLAN
I.  GENERAL

    The Sanitary Water Board, in accordance with its powers under the
Clean Streams Law, will issue appropriate orders, modify permits or take
other appropriate action to have all persons or municipalities under its
jurisdiction abate pollution to comply with the criteria.  The Board, in
all cases, will require either immediate abatement or the submission of
 a detailed abatement schedule providing for abatement within as short a
period of time as is* technically possible and will cause appropriate
investigations to be made to assure itself of compliance with the standards.

    Facilities are expected to be designed to meet the criteria at the
critical periods.  In addition, facilities must be operated at all times
at that level of efficiency needed to meet requirements for the critical
conditions.  This will result in stream quality higher than the criteria
most of the time.

II.  SPECIFIC

    A minimum of secondary treatment, or its equivalent, is required
for all waste discharges in this area.

    Secondary treatment is that degree of treatment which, in the opinion
of the Sanitary Water Board, will remove practically all of the suspended
solids; will remove at least eighty-five (85) percent of the organic
pollution load as measured by the biochemical oxygen demand testj will
accomplish the removal of oils, greases, acids, alkalis, toxic, putrescible,
taste and odor producing substances, and other substances inimical to the
public interest in the receiving streamj will provide effective disinfection
to control disease producing germs; will provide satisfactory disposal of
sludge; and will produce a final effluent that is suitable for discharge into
the receiving waters.

B.   Physical and Chemical Quality;




     1.  Physical Quality




          (a)  Color exceeded the Pennsylvania Standard set for the




West Branch and the Main Branch from the point of discharge of the P. H.




Glatfelter's Treatment Plant outfall at river mile 24.5 to approximately




the sample point at river mile 10.6.  The color increased again at the




discharge for the York City Treatment Plant outfall at river mile 9.0




to the last sample point at river mile 0.6.




     Color in excess of 50 units (Platinum - cobalt method) may limit




photosynthesis and have a deleterious effect upon aquatic life, par-




ticularly phytoplankton, and the benthic biota.  Color can modify water




temperature and fish will have difficulty finding food.  (See Figure III)




          (b)  Turbidity was not included in the Pennsylvania Water




Quality criteria   however, the National Water Quality committee set




criteria  as follows:  "Turbidity in the receiving water due to a




discharge should not exceed 50 JTU in warm-water streams or 10 JTU in




cold-water streams."




     This parameter is exceeded from the sample point at river mile




32.6 to the confluence of the West Branch and Oil Creek at river mile




28.1.  This Section is classified by Pennsylvania as cold-water




fishery.  (See Figure IV)
                                  -28-

-------
          (c)  Temperature standards were only exceeded from the




sampling point at P. H. Qlatfelter's Treatment Plant outfall at river




mile 24.5 to the sampling point at river mile 14.4.  Warm waste dis-




charges raise the temperature of the receiving waters with the following




concomitant effects:




(a)  higher temperatures diminish the solubility of dissolved oxygen




and thus decrease the availability of this essential gas,




(b)  elevated temperatures increase the metabolism, respiration, and




oxygen demand of fish and other aquatic life, approximately doubling




the respiration for a 10 C rise in temperature; hence the demand for




oxygen is increased under conditions where the supply is lowered,




(c)  the toxicitv of many substances is intensified as the temperature




rises,




(d)  higher temperatures militate against desirable fish life by




favoring the growth of sewage fungus and the putrefaction of sludge




deposits, and finally




(e)  even with adequate dissolved oxygen and the absence of any toxic




substances, there is a maximum temperature that each species of fish or




other organism can tolerate; higher temperatures produce death in 24




hours or less.  (See Figure V)




          (d)  pH in most fresh, natural waters usually has a range




between 6.5 and 8.5.  In primary contact recreation waters, the pH




should be within the range of 6.5 and 8.3.  The pH range for surface




water  criteria  for  public water supplies  is  6,0  to  8,5,   (See Figure VI)
                                   -29-

-------
          (e)  Solids in general are high; however, the concentrations




are within the limits of water quality criteria for designated usage.




Dissolved solid concentrations limit the light penetration, which in




turn limits the food chain for aquatic growth.  Soil runoff has produced




some sediment problems, and is indicated in the concentration increase




of suspended solids during rainstorms.

     2.   Chemical Quality




          (a)  Dissolved Oxygen, Biochemical Oxygen Demand, Chemical




Oxygen and Total Organic Carbon.




     The results of these analyses were not completely representative




Concentrations of various chemicals, metals and organic material




(i.e., tennins and lignins) inhibited the bacterial action and inter-




fered with the chemical procedure for determining dissolved oxygen and




the biochemical oxygen demand.   However, the analyses indicated that




there is a definite problem in the Codorus Creek which establishes an




existence of a number of dissolved oxygen values   lower than accept-




able limits.  (See Figure VII)




     A bacterial seed for the biochemical oxygen demand determination




is required,  This requires a period of one to two months to develop.




     A mathematical model for the oxygen balance could not be de-




veloped.  Recommendation is made that in the summer of 1972 additional




samples be taken after a proper seed has been developed to determine




the dissolved oxygen concentrations and long term biochemical oxygen




demands, with the resultant deoxygenation rate values.




     When Chemical Oxygen Demand analyses are made, organic matter is




converted to Carbon Dioxide and water regardless of the biological




assimilability of the substances.  Therefore, C.O.D. values are greater




than B.O.D. values when significant amounts of biologically resistant




organic matter is present.

     Nutrient concentration in this Basin is adequate to stimulate




troublesome growth of algae and aquatic plants.  The color concentration




has limited this reaction.  Evaluation of the Main and West Branches,




including loadings from wastewater treatment facilities and tributaries,




indicates that the impoundments at Spring Grove, for the Glatfelter




Company, reduced nutrients and the discharges from the wastewater




treatment facilities of Spring Grove and Glatfelter increased the loading




on the stream.  However, the major loading occurred within the city of




York, either from the municipal facilities or the industrial complex.




(See Figure VIII)




     Approximately 40 per cent of the total phosphorous and 20 per cent




of the total nitrogen entered the surface waters from the municipal




wastewater treatment facilities.   The remainder    was discharged from




industry and agricultural activities.




     All wastewater treatment facilities sampled, except Penn Township,




exceeded the Pennsylvania concentration limit of 1.5 mg/1 for ammonia




(as N) as a toxic material.




          (c)  Metals




     Analyses for various toxic heavy metals were conducted; however,




only three were present in measurable quantities.   (See Table D)  Two




of these, zinc and aluminum, are attributable to the metal finishing
                                  -38-

-------
wastewater.  Mercury, the third toxic metal, is harmful to aquatic life,




wildlife and human life, and comes from industrial wastes.




     The concentration of aluminum in this Basin does not appear to be




toxic to the aquatic life.  The high concentration noted at Station




SCOOOO was more likely from wash water from the water treatment plant




in the form of aluminum hydroxide.  Any concentration more than 0,5 mg/1




will cause acute eye irritations.  If any portion of this stream is to




be used as a body contact sport the concentration must be lowered to




less than 0.1 mg/1 to eliminate the eye irritation problem.




     The Pennsylvania Water Quality Standards set the zinc toxic con-




centration at a maximum of 0.05 mg/1 for this basin.  Most locations




exceed this limit.  Zinc is affected by the degree of hardness.  This




stream has hard water since the total hardness (as Calcium Carbonate)




exceeds 120 mg/1 at most locations.  Calcium is antagonistic toward




the toxicity of zinc.  Therefore, the concentrations of zinc are not a




hazard in the aquatic environment.




     Mercury is a highly toxic metal.  All municipal and industrial




wastewater facilities sampled indicated measurable amounts of mercury.




Other industries in the area appear to be discharging mercury into the




receiving waters also,  The sources of discharge of this metal should




be  identified and eliminated.
                                  -39-

-------
     Pennsylvania has set a limit of 1.5 mg/1 of total iron, and the




Water Quality Criteria established by NTAC sets a limit of 0.3 mg/1




of iron, 0.05 mg/1 for manganese for the usage classification of this




stream.




     Iron and manganese concentrations vary within the various areas of




the Basin and exceed the above mentioned limits.  Most high concentra-




tions are from municipal and industrial wastewater discharges, and from




backwashing of municipal water treatment plant filters.  Iron, at




present concentrations, may cause problems with live stock watering




and fish.  Cows will not drink this type of water which results in




lower milk production.  Irritation and blocking of  respiratory channels




in fish along with the smothering of eggs due to iron sedimentation will




reduce the fish population.

    (d)  Miscellaneous Chemicals (See Table E)




         Chlorides are found in most natural waters.  In this Basin




they could be of natural mineral origin and derived from human or animal




sewage; from salts spread on fields for agricultural purposes; or from




industrial wastes.  The highest concentration is discharged from the




Glatfelter plant.




      Sulfates are also found in most natural waters.  Sulfates are dis-




charged in numerous industrial wastes,  Glatfelters plant discharges




the highest concentration.




      Total Hardness, as Calcium Carbonate, determination along with




Calcium and Moynesium indicate the characteristic of this stream is hard,




This is generally due to the geology of the basin.

C.  Bacteriological Quality:

     All bacteriological determinations were accomplished by the Mem-

brane Filter technique,

     (1)  Total coliforms are introduced to water courses via water

run-off and wastewater outfalls.  They are considered significant as

indicator organisms because of their predominance in the intestinal

tracts of warmblooded animals.  The fecal coliform density is roughly

proportional to the amount of excremental waste present,  With ex-

ceptions, elevated coliform populations are suggestive of significant

contamination by excrement of warmblooded animals.  Several factors

which cause fluctuations in total coliform populations are summarized

as follows:

               Higher                     Lower

          Sewage intrusion                pH changes

          Nutritive effluents             Temperature changes
          (Containing sugar, dairy
           wastes, etc,)

          Storm drains                    Land run-off  (prolonged flow)

          Land run-off                    Toxic wastes
          (Initial flow)

Total coliform population limits set by Pennsylvania for this watershed

are for the period May 15 to September 15 of any year; not to exceed
                                  -45-

-------
1000/100 ml as an arithmetic average value; not to exceed 1000/100 ml

in more than two consecutive samples; not to exceed 2400/100 ml in

more than one sample.  For the period September 16 to May 14 of any

year; not to exceed 5000/100 ml as a monthly average value, nor to

exceed this number in more than 20 per cent of the samples collected

during any month; nor to exceed 20000/100 ml in more than 5 per cent

of the samples.

     The National Technical Advisory Committee to the Secretary of the

Interior on Water Quality Criteria limits the total colifora by watershed

usage as follows:

          Water Supply - 10,000/100 ml as permissable; less than
                         100/100 ml as desirable

          Agricultural Usage - 5,000/100 ml as the monthly arithmetic
                               average density for two consecutive
                               samples; 20,000/100 ml for any one sample

     The West and South Branches along with the Main Section of the

Codorus Creek exceeds the National Water Quality Criteria and Penn-

sylvania Criteria.  The East Branch of the Codorus Creek, the Mill

Creek and the Oil Creek appear to meet the standards.  (See Figures

IX and X)

     (2)  Fecal coliforms are gaining notoriety as pollution indicies

because of their relatively infrequent occurrence, except in associa-

tion with fecal pollution.  Moreover, because survival of the fecal

coliform group is shorter in water courses than for the coliform group

as a whole, high fecal coliform levels indicate relatively recent

pollution.
                                  -46-

-------
National Water Quality Criteria for fecal coliforms is as follows:

    Primary Contact Recreation         2OO/1OO ml

    General Recreation                2OOO/1OO ml

    Public Water Supply               20OO/10O ml permissable
                                        20/1OO ml desirable


The entire watershed with the exception of the East Branch of

the Codorus Creek and Mill Creek is only suitable for General

Recreation as indicated by this bacteriological indicator.


    (3)  Fecal Streptococci do not occur in pure water or virgin

soil, their presence in water courses indicates the existance of

warmblooded animal pollution.  Their validity as an index of

pollution is enhanced by their inability to reproduce in water

courses.  The following points should be considered when inter-

preting fecal streptococci data:

         (a)  The presence of this indicator in untreated water

indicates the presence of fecal pollution by warmblooded animals.

         (b)  Where the source and significance of the coliform

group are questionable, the presence of this group should be

interpreted as indicating that at least a portion of the coliform

group is derived from fecal sources.  Water quality criteria for

fecal streptococci has not been established, however, their presence

in the entire watershed is an indication that there is fecal pollution

present.

    (4)  Fecal streptococci determinations, when accompanied by fecal

coliform studies, serve as a valuable tool in the differentiation
                               -47-

-------
of animal from human wastes.  In intestinal wastes of human origin,




the ratio of number of fecal coliforms to number of fecal streptococci




tends to be greater than four.  When this ratio is less than O.7,




this suggests pollution derived predominately or entirely from




livestock or poultry wastes.  Ratios falling between 4.O - 0.7 are




not quite so certain.  Limitations to this ratio are:




         (a) Samples taken within 24 hours of flow time from origin




of pollution.




         (b)  p'H range of 4.0 to 9.0.




These limitations do not appear to affect the results of this study.






The results of this study indicates bacteriological pollution is




caused mainly by livestock or poultry wastes.  There are some




indications of human waste pollution.

D.  Biological Quality:  (See Figure XI)




      This portion of the study was accomplished in 1966 as a tributary




to the Susquehanna River Basin.




      COR - 001 about 0.5 mile below LR66152 Bridge, York County.




      At mile 1, Codorus Creek had recovered to the point where it




supported 13 kinds of bottom organisms.  However, pollution-tolerant




Physa sp. snails, sludgeworms, and leeches still predominated.  The




Susquehanna River receives an organic pollution loading from the




inflow of Codorus Creek.




      COR - 006 about two miles below Bridge at intersection of T-839




and LR66021.




      Below the City of York, significant organic pollution was in-




dicated.  Only four kinds of bottom organisms were found, with sludge-




worms making up 1,191 of the 1,196 organisms in the quantitative sample.




      COR - 014 at Pennsylvania Route 182 Bridge above York, Penna.




      Codorus Creek was sampled immediately below the confluence of the




West Branch and the South Branch, and upstream from the City of York,




Pennsylvania.  Seven kinds of bottom organisms were found in the




population of 35 organisms per square foot.  Among these were three




kinds of caddis flies.  Biological conditions at this station showed




an average of the high quality from the South Branch and the low




quality from the West Branch.

    WCO - 016 at First Bridge on LR6621O above Indian Rock Dam,




York County




    This station was just above the confluence of the West Branch




with the South Branch Codorus Creek.  Only one genera was present;




however, the size of the boulders in the stream did not permit




collection of a quantitiative sample.  This genera was the pollution-




tolerant Physa snail, which was very abundant.  Organic pollution is




still indicated at this station.




    WCO - 019 at Pennsylvania Route 616 Bridge, North of New Salem,




Penn sy1vani a




    About eight miles below Spring Grove, at mile 18, further




biological degradation from organic pollution was observed, with a




reduction in the number of kinds to four.  Again sludgeworms (1,945




per square foot) and air-breathing snails (895 per square foot)




constituted the majority of the total botton organism population of




2,844 organisms per square foot.




    WCO - 025 at T-452 Bridge, York County




    This station was just below Spring Grove and reflected the




results of organic pollution from the Spring Grove area.  Only five




genera were found, and pollution-tolerant kinds (air-breathing snails




and sludgeworms) dominated the population of 646 organisms per square




foot.




    WCO - O28 South of LR66008 South of Spring Grove, Pennsylvania




    Codorus Creek is formed by the juncture of its South Branch and




West Branch at stream mile 14.1.  The West Branch is considered the




main stem.  The first station on this tributary was located upstream




from Spring Grove at mile 27 on the West Branch.   Good quality water




                             -53-

was indicated by the 18 kinds (genera) of bottom organisms which




included clean-water associated caddisflies and mayflies,  with a




population of 275 per square foot.




    SCO - OOO near York, Pennsylvania Pumping Station below dam




    The South Branch was sampled near its mouth, and unpolluted




biological conditions were found to exist.  Thirteen genera of




bottom organisms'were found in the population of 223.  These genera




included many clean-water associated forms.




    Main Stem - SUQ - 043 at Wrightsville (W. B.) above US 30 Bridge




    The last station on the Susquehanna River West Bank was located




at Wrightsville, Pennsylvania, opposite the Columbia, Pennsylvania,




station on the East Bank.  The number of kinds of bottom organisms




here was reduced to ten, with 245 per square foot.  Although clean-




water associated forms perdominated, with caddisflies (the dominant




form), scuds, mayflies, and gill-breathing snails present, the




reduction in number of kinds reflected the deleterious effects of




Codorus Creek, which enters in this reach.






Biotic Index  (An index valve based on biological findings and




indicative of the cleanliness, with regard to organic pollution




of a portion of a stream)




    Determinations at each of the stream stations was made for the




number of species of organisms that tolerate no appreciable organic




pollution (Class I) and the number of species that tolerate moderate




organic pollution but cannot exist under near anaerobic conditions




(Class II).







                                -54-

-------

-------
Biotic Index =  2(N Class I) + (N Class II)




                N = Number of Species







The index may vary from O to 40.  Above 10 is indicative of a




clean stream; a reading from 7 to 9 indicates an enriched stream;




a moderately polluted stream has readings between 1 to 6; a O reading




indicates a grossly polluted stream. (See Figure XII)

             SOURCES OF WASTEWATER DISCHARGES






A.  Domestic Wastewater Discharges;  (See Tables F and G)




    All six (6) municipal wastewater treatment facilities located




in the Codorus Creek Basin discharge both domestic and industrial




treated wastewater.  Located in this basin are four (4) small




school treatment facilities and one (1) discharge from a trailer




court.  Only the six (6) municipal outfalls were sampled during




this study.




    Springettsbury Township MUA facility utilizes a contact




stabilization process, chlorination and followed by a polishing




lagoon before discharging into the Codorus Creek.  The capacity




of this facility is 8MGD.  Nutrients appear to be high in the




wastewater discharge.  Since this is a new facility, the plant




is experiencing some problems due to industrial wastes being




discharged in the collection system without adequate pretreatment.







    The City of York facility is also using the contact




stabilization process followed by chlorination, and has a




capacity of 18 M.G.D.  There is a plant by-pass; however, the




by-pass flow can be chlorinated.  All parameters analyzed indicate




that this facility should be upgraded to meet water quality




standards for this section of the watershed.  Also, enforcement




of the industrial waste ordinance is required.
                              -57-

-------
Imhoff tanks followed by a standard rate trickling filter and


chlorination is the process utilized by the Spring Grove facility


with a capacity of O.25 M.G.D.  This facility is outdated and in


poor condition with the resulting poor effluent quality.  Extensive


upgrading is required.  The P. H. Glatfelter treatment plant


requires the addition of nutrients to its industrial waste. Before


Spring Grove undertakes any upgrading, they should investigate the


feasibility of combining their waste with Glatfelter, thus pro-


viding the nutrients for the industrial waste.


    The Penn Township treatment plant utilizes the contact


stabilization process and chlorination to treat its wastes.  The


plant capacity is 1.2 M.G.D. for parameters investigated.


Concentrations indicate an upgrading for existing criteria require-


ments.  Industrial wastes discharged to this plant also appear to


lower treatment efficiencies.


    The contact stabilization process at Glen Rock is followed by


chlorination and a polishing pond.  The capacity is 0.3 M.G.D.


Nutrient removal is still a requirement for this facility.

        Red Lion facility is to by phaaad-^ut ahoi-tlj/.  An


intercepter from this facility to the Springettbury Township plant


has been proposed.  Federal and State funds have been applied for.

B.  Industrial Waste Discharges:  (See Tables I, J, and K)




      There are three recorded lists of industrial wastewater discharges




into the Codorus Creek Basin.  These lists do not agree, and a study




would be required to determine which industries discharge directly




into the Codorus Creek Watershed and those that discharge into muni-




cipal wastewater treatment facilities.




      The laboratory results, as show in the Appendix, indicates a




high concentration of heavy metals, solids, color and oxygen demanding




materials which could be attributed to the types of industries located




in this watershed.  Metal finishing or plating industries contribute




heavy metals, color and solids.  Paper industries contribute color,




solids and oxygen demanding substances.  The agricultural and food




processing industries contribute nutrients, oxygen demanding materials,




turbidity, solids and bacteria.




      One industry was sampled, P. H. Glatfelter, which discharges




into the West Branch of the Codorus Creek.  Average outfall loadings




to the stream are listed in Table H.




      The various parameters examined indicate additional treatment is




required to meet the water quality standards required for this portion




of the watershed.  The existing system includes primary with chemical




treatment followed by a secondary process.
