                         FOREWORD
    The National Eutrophication Survey was initiated in 1972 in
response to an Administration commitment to investigate the nation-
wide threat of accelerated eutrophication to fresh water lakes and
reservoirs.

OBJECTIVES

    The Survey was designed to develop, in conjunction with state
environmental agencies, information on nutrient sources, concentrations,
and impact on selected freshwater lakes as a basis for formulating
comprehensive and coordinated national, regional, and state management
practices relating to point-source discharge reduction and non-point
source pollution abatement in lake watersheds.

ANALYTIC APPROACH

    The mathematical and statistical procedures selected for the
Survey's eutrophication analysis are based on related concepts that:

        a.  A generalized representation or model relating
    sources, concentrations, and impacts can be constructed.

        b.  By applying measurements of relevant parameters
    associated with lake degradation, the generalized model
    can be transformed into an operational representation of
    a lake, its drainage basin, and related nutrients.

        c.  With such a transformation, an assessment of the
    potential for eutrophication control can be made.

LAKE ANALYSIS

    In this report, the first stage of evaluation of lake and water-
shed data collected from the study lake and its drainage basin is
documented.  The report is formatted to provide state environmental
agencies with specific information for basin planning [§303(e)], water
quality criteria/standards review [§303(c)], clean lakes [§314(a»b)L
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.

-------
                                iii
    Beyond the single lake analysis, broader based correlations
between nutrient concentrations (and loading) and trophic condi-
tion are being made to advance the rationale and data base for
refinement of nutrient water quality criteria for the Nation's
fresh water lakes.  Likewise, multivariate evaluations for the
relationships between land use, nutrient export, and trophic
condition, by lake class or use, are being developed to assist
in the formulation of planning guidelines and policies by EPA
and to augment plans implementation by the states.

ACKNOWLEDGMENT

I.   CONCLUSIONS
    A.   Trophic Condition:
        1.   Lake Champlain exhibits a variety of trophic  conditions  rang-
        ing from near oligotrophic in the  deeper main  lake  areas  to  eu-
        trophic in some of the bays and near-shore areas.
        2.   South Lake Champlain has  characteristics commonly associated
        with eutrophy, i.e., shallow  and  nutrient rich; however,  primary
        production in South Lake Champlain is apparently suppressed  by
        natural turbidity caused by non-biological materials.
        3.   While the main water body of Lake Champlain is  currently in
        an acceptable trophic condition,  some of the embayments and  the
        South Lake Champlain have shown signs of accelerated eutrophication,
        It is believed that the continued addition of unnecessarily high
        quantities of phosphorus will shorten the useful life of the lake.
    B.   Limiting Nutrient:
        1.   The algal assay tests indicate that phosphorus is the nutrient
        of major importance in controlling primary production in Lake
        Champlain.
    C.   Nutrient Controllability:
        1.  The average yearly total  phosphorus input from point and non-
        point sources to  Lake Champlain is estimated to  be 1,318,650
        pounds before the New York phosphate detergent ban.

-------
        2.  Of the total phosphorus input to Lake Champlain before the
        New York phosphate detergent ban, New York point sources (muni-
        cipal and industrial) accounted for 11% (140,270 pounds) of the
        total annual input and Vermont point sources accounted for 19%
        (253,100) of the total annual input.
        3.  After the New York phosphate detergent ban*, the total annual
        phosphorus input to Lake Champlain is estimated to be 1,260,510
        pounds.
        4.  Of the total phosphorus input to Lake Champlain after the New
        York phosphate detergent ban*, New York point sources accounted
        for 7% (82,230 pounds) of the total annual input and Vermont point
        sources accounted for 20% (253,100 pounds) of the total input.
        5.  The total annual nitrogen input to Lake Champlain is 28,928,400
        pounds.
        6.  Of the total annual nitrogen input, only a maximum of 9% is
        contributed by New York and Vermont point sources.
        7.  The annual total phosphorus loading to South Lake Champlain
        from all  sources before the New York phosphate laundry detergent
        ban was 197,350 pounds.
        8.  Of the total phosphorus input to South Lake Champlain before
        the ban,  New York point sources contributed 31% (60,390 Ibs) and
* The assumption was made that the New York phosphate laundry detergent
  ban will decrease the annual phosphorus load from New York municipal
  sewage treatment plants by 50%.

-------
      New York diffuse sources contributed 27% (54,080 Ibs) of the total.
      Vermont point sources contributed 7% (13,650 Ibs) and Vermont
      diffuse sources contributed 35% (69,230 Ibs) of the total.
      9.  After the New York phosphate laundry detergent ban*, the
      total phosphorus input to South Lake Champlain is estimated
      to be 179,200 pounds per year.
      10.  Of the total phosphorus input to South Lake Champlain
      after the New York ban, New York point sources contributed
      24% (42,240 pounds) and New York diffuse sources 30% of the
      total.  Vermont point sources contributed 8% (13,650 pounds)
      and Vermont diffuse sources 38% (69,230 pounds) of the total.
  D.  Phosphorus Reduction:
      1.  In that primary production in the waters of Lake Champlain
      is stimulated by the addition of phosphorus, phosphorus inputs
      from all sources should be minimized to reduce the eutrophica-
      tion rate.
      2.  Prior to the New York phosphate detergent ban, the loading
      rate to Lake Champlain was 0.53 grams total phosphorus/m  lake
      surface area/year.
      3.  If phosphorus inputs from New York and Vermont municipal
      and industrial  discharges were decreased by 80% or equivalent
      reductions in phosphorus inputs from non-point sources were
The assumption was made that the New York phosphate laundry detergent
ban will decrease the annual phosphorus load from New York municipal
sewage treatment plants by 50%.

-------
attained, the loading rate to Lake Champlain would be reduced
to 0.40 grams/m2/year, or to 75% of the pre-ban loading rate.
4.  According to the Vollenweider relationship, a loading rate
of 0.53 grams total phosphorus/m2/year is equivalent to a eu-
trophic condition for a lake with the morphometric character-
                                                            2
istics of Lake Champlain, whereas a loading rate of 0.40 g/m /
year corresponds to a mesotrophic loading rate.

II.  INTRODUCTION
    The National Eutrophication Survey was established by EPA in late
1971 with the directive to investigate all significant lakes and reser-
voirs in the contiguous United State which receive effluents from muni-
cipal sewage treatment facilities.  The stated objectives of the Survey
were to determine the extent of eutrophication in each water body and
to assess the total nutrient input to each water body, differentiating
between inputs from point-sources (primarily municipal) and diffuse
land runoff.  The goal was to determine the controllability of nutrients
(particularly phosphorus), the impact of point source and non-point source
nutrients on each study lake and the expected benefit to each lake by
reducing the point-source nutrient inputs.
    This report is concerned primarily with the trophic condition,
nutrient levels and nutrient loadings of the waters of Lake Champlain
and represents a preliminary assessment of the data gathered by the
Survey from June, 1972 through June, 1973.  Lake Champlain  is but one
of approximately 484 water bodies east of the Mississippi now being
studied by the Survey, albeit an  important one due to its size and the
fact that it borders the States of New York and Vermont as  well as the
Canadian Province of Quebec.
     In this report "Lake Champlain"  refers to the entire lake which  is
defined as the portion extending  from the southern tip of South Bay  near
Whitehall, NY to the  Richelieu River outlet.  The total drainage area of

-------
 the  Lake  Champlain  basin  is approximately  7,744 square miles not in-
 cluding the  Lake  Champlain water  surface area which is approximately
 436  square miles.   Lake Champlain can be described as long and narrow
 with a maximum  length of  109 miles and a maximum width of 11 miles.
 The maximum  depth of Lake Champlain is 400 feet and the mean depth is
 64 feet.  The mean  hydraulic detention time  is approximately 2.6 years.
     In this  report, "South Lake Champlain" refers to that portion of
 Lake Champlain  extending  from the southern tip of South Bay near White-
 hall, NY  to  the Crown Point Bridge.  The total drainage area of South
 Lake Champlain  is 1,216 square miles not including the South Lake Cham-
 plain water  surface area  which is 22 square  miles.  South Lake Champlain
 is also long and narrow with a maximum length of 37 miles and a maximum
 width of  less than  two miles.  The maximum depth of South Lake Champlain
 is 46 feet and  the mean depth is 8 feet.  The mean hydraulic detention
 time is approximately 40  days.
    Separate phosphorus loading estimates were prepared for Lake Champlain
 and South Lake Champlain  in this report.  A  nitrogen loading estimate
was prepared only for Lake Champlain in its  entirety.
    The map on page x indicates the approximate location of each sampling
site and delineates the U.S. portion of the  Lake Champlain drainage area.
The map on page xi shows only South Lake Champlain and its drainage area.

IV.   LAKE WATER QUALITY  SUMMARY

     EPA field staff sampled  13  stations  in Lake Champlain during the

 spring, summer,  and fall  seasons of 1972.  Dates for each of the three

 samplings were June 1 - 2, July 30 - August 2, and October 5-8.  Ap-

 proximate locations of  the sampling sites are depicted on the maps, on

 pages  x and  x1.   Specific locations and  depth characteristics of each

 station from the southern to the northern end of Lake Champlain were as

 follows.   The complete  set of lake data  for each station is in Appendix

 C of this report.

    21 feet (Latitude 44°48I00"N, Longitude 73°12'30"W).
Station 500113:  located in mid-lake, due west of Point au Per;
    maximum depth of 25 feet (Latitude 44056'25"N, Longitude

A.  Physical and Chemical Characteristics:
        To briefly summarize the grouping of stations according to
    the morphometry of the lake, stations 500101, -02, -03, and -04
    were located in South Lake Champlain (south of Crown Point);
    stations 500105, -06, -12, -07, -09, -10, and -13 were located
    in the main lake between Port Henry and Rouses Point; station
    500108 was located in the Malletts Bay area; and station 500111
    was located in the northeastern portion of Lake Champlain.
        To simplify the presentation and discussion of the results
    of lake sampling, data from stations which were related geographi-
    cally or morphometrically are grouped.  For each grouping,  a sum-
    mary table is provided which gives maximum, minimum, and mean
    values of all observations at the grouped stations and mean values
    for each sampling date.

-------
                          12
     The mean parameter values  presented  in  the  tables are not
 volume-weighted to account  for differences  in nutrient levels
 occurring  in the various  layers of  the lake during stratifica-
 tion.   Nevertheless,  the  mean  values  are  useful as a general
 guide  to differences  in water  quality between areas.
     Table  1  summarizes  the  combined data  for stations 500101,
 -02, -03,  and -04,  all  of which were  located in South Lake
 Champlain.
     Secchi disc  transparencies  in South Lake Champlain were low
 during  EPA visits  in  1972 with  a maximum  depth of 52 inches in
 Ticonderoga  Bay, which may  have been  caused by the diluting effect
 of the  discharge through  the Lake George  outlet, and a minimum of
 3 inches.  Observations by  the  field  staff indicate the turbidity
 was  caused primarily  by suspended sediments although some surface
 algae were also evident.  Hensen and  Potash (op. cit.) stated that
 South Lake Champlain  was  characteristically turbid, apparently due
 to natural shoreline  erosion.
    The  chemical data indicated  that  nitrogen and phosphorus
were relatively abundant  in waters  of the South Lake and, parti-
 cularly, that the contribution  from the Delaware-Champlain Canal
and Poultney River system was rich  in nutrients.  The availability
of nutrients in South Lake was  not matched by correspondingly high
chlorophyll a_ values during EPA  samplings—probably due to the
high turbidity which prevented plankton blooms from developing;

however, during August and September of 1972, algal blooms were
observed by staff of the Vermont Department of Water Resources
and T. W. Beak Consultants, Limited.  The algal genera Aphani-
zomenon and Melosira predominated on those occasions.
    Station 500104, the deepest EPA station in the South Lake,
was stratified during the June, 1972 sampling; however, there
was no apparent oxygen depletion in the hypolimnion at that time.
During the August sampling at station 500104, stratification was
not as pronounced, indicating that the shallow depth of the South
Lake permits periodic mixing to occur throughout the summer.
    In summary, the South Lake area can be characterized as gen-
erally having poorer water quality than other areas of the lake
as evidenced by high phosphorus concentrations and low Secchi disc
readings.  South Lake Champlain has the characteristics of a
eutrophic water body although primary productivity is apparently
suppressed by the high turbidities which occur in that portion
of the lake.  South Lake Champlain waters, which are relatively
high in phosphorus, could conceivably stimulate primary produc-
tion in the main lake as the waters mix and the turbidity-causing
materials settle.  It is also possible, however, that the excessive
phosphorus is adsorbed to the silt and becomes unavaiable for algal
assimilation when the silt settles to the lake bed.

-------
                         15
    Table 2 summarizes the data for stations 500105, -06,  and -12.
Perhaps station 05 should not have been included in this group
as the water quality there reflects the South Lake Champlain
influence to a great extent because of proximity to Crown Point.
Generally speaking, water quality in Lake Champlain between Crown
Point and Thompson's Point was much better than in South Lake
Champlain.  Secchi disc readings ranged from 27 - 144 inches, total
phosphorus concentrations did not exceed 0.032 ppm., and there was
no evidence of dissolved oxygen depletion in the hypolimnion.
One extremely high chlorophyll a^ value (67.7 ug/1) at station 05
probably resulted from the combination of South Lake Champlain
and Port Henry, NY nutrient contributions to the area.
    In summary, the area of the lake between Crown Point and
Thompson's Point could best be classified as mesotrophic or
perhaps mildly eutrophic.  Although chlorophyll a. values were
among the highest measured, there was no evidence of significant
dissolved oxygen depletion in the hypolimnion.
    Summary data for station 500107, -09, and -10 are presented in
Table 3.  These stations were all located in the main lake water
mass between Schuyler Island and Cumberland Head.  Secchi disc
readings in this area were relatively high, ranging from 72 to 168
inches and averaging 122 inches.  Total phosphorus  concentrations
were low, averaging only 0.018 ppm in the area.  Although the water
was thermally stratified at stations 500107 and 500109  during the

July sampling, there was no evidence of significant oxygen deple-
tion in the hypo limn ion.  Chlorophyll ^values at stations 500107,
-09, and -10 averaged somewhat lower than the previous group of
stations further south and ranged from 5.4 to 29.2 micrograms/
liter with a mean of 11.1 micrograms/liter.  Overall the area
would be classified as mesotrophic although signs of oligotrophy
were also evident.
    Table 4 summarizes the data for station 08 in the Mallets
Bay area which was sampled only during July and October of 1972.
Secchi disc readings at this station were among the highest
observed in the entire lake with a maximum reading of 172 inches.
Total phosphorus concentrations were low, ranging from 0.007 ppm
to 0.021 ppm and averaging 0.012 ppm.  Specific conductance was
also somewhat less at this location than other sites on the lake
with a mean of 106 micromhos.  The lake was stratified in the
Malletts Bay area during both the July and October samplings,
and dissolved oxygen concentrations in the hypolimnion were
approximately 24% of saturation, which is symptomatic of a meso-
trophic condition.  Settling of previous algal blooms could ac-
count for the high Secchi disc readings which were observed.
Potash, Sundberg, and Henson (op. cit.) classified the Malletts
Bay area as eutrophic and noted that hypolimnetic oxygen concen-
trations dropped as low as 0.1 mg/1 during the summer of 1967.

    Table 5 summarizes the data from station 500111 in the north-
east arm of Lake Champlain.  Total phosphorus concentrations
averaged higher in this area than for all other Champlain sta-
tions except for those in South Lake.  Secchi disc readings were
generally high with summer and spring values of 168 and 178 inches
respectively.
    Station 500111 was shallow and was not stratified during the
1972 sampling dates.  A significant difference between station
500111 and the other sampled areas of the lake was the low in-
organic nitrogen concentrations.  Mean inorganic nitrogen values
were approximately 41% of the lowest mean observed in any of the
other areas.  The overall classification in the Northeast area
of Lake Champlain is mesotrophic to mildly eutrophic.
    Table 6 summarized data from station 13 located in the north-
west part of the main water mass of Lake Champlain.  This station
was relatively shallow (25 feet) and was not stratified during
the sampling periods.  Total phosphorus concentrations averaged
0.017 ppm and Secchi disc readings were consistently high, ranging
from 125 - 168 inches.  This area of the lake would be classified
as mesotrophic.

Lake Champlain and assigns a trophic condition to each general

lake area.  From an overall standpoint, Lake Champlain waters
cover a gamut of trophic conditions ranging from oligotrophic
in main lake areas to eutrophlc in some embayments and near-
shore areas.  If one classification were assigned to the
entire lake, mesotrophy would be most appropriate.

B.  Limiting Nutrient Studies:
        Two sets of algal  assay samples  were  processed  by  the
    National  Eutrophication Survey.   The first set of ten  samples was
    collected by staff members  of the Vermont Agency of Environmental
    Conservation and T. W. Beak Consultants on September 27  and  Octo-
    ber 3, 1972.  These samples were all collected in South  Lake
    Champlain in the general  area from two miles  south  of  Chipmans
    Point to three miles north  of the International  Paper  Company
    effluent diffuser (see Figure 3).  Each sample was  frozen  and,
    following the last collection, all of the samples were packed  in
    ice and sent air freight to Corvallis, Oregon on October 3,
    arriving October 6, 1972.
        The second set of algal assay samples., which involved  all  of
    Lake Champlain, was collected by EPA during October 5-8, 1972.
    Because of limitations on the number of assay samples  which  could
    be processed from each of the lakes included in the Survey,  only
    three samples from Lake Champlain were assayed.  Each  of the
    three EPA samples were depth-integrated and composited from  mul-
    tiple sampling sites on the lake as follows:
        Assay Sample 72:  contained equal portions of water from EPA
            stations 500101, -02, -03, and -04 (all South  Lake Champlain)
        Assay Sample 78:  contained equal portions of water from EPA
            stations 5001C5, -06, -07, and -12.

    Assay Sample 66:  contained equal  portions of water from EPA
        stations 500108, -11, and -13.
    EPA stations 500109 and -10 were not included in any of the
        assay samples.
    The algal assays were generally performed according to the
procedures outlined in the Algal Assay Procedure Bottle Test
published by EPA (1971).  The test organism was the green alga,
Selenastrum capricornutum.  The cultures were inoculated for
two weeks at 24°C with continuous shaking under 400 foot-candles
of lighting.  Growth of the cultures was monitored by periodic
determination of cell  numbers with electronic particle counters.
Cell numbers were converted to equivalent dry weight values using
a predetermined calibration curve.
    The growth curves and chemical analyses of both the Vermont
and EPA algal assay samples appear in Appendix D.
    The results of the Vermont samples from South Lake Champlain
will be discussed first.  These results are summarized in Table
8 which (1) identifies the sample, (2) indicates the treatment
given to the sample, (3) lists available nutrient concentrations
at the time the growth period started, and (4) lists the algal
yield in terms of mg/1 dry cell weight at the conclusion of the
14 day incubation period.  The results are presented in the gen-
eral order of sample site location from the southernmost sampling
site to the northernmost sampling site.

    There was laboratory error in the preservation of subsam-
ples taken for chemical analysis from the original Vermont sam-
ples (see Appendix E for Gakstatter Memo of February 1,  1973).
The preservation error could well have influenced the concentra-
tion values for orthophosphate and inorganic nitrogen given in
Table 8 although the assay response should not have been affected.
    The samples, for which assay results are given in Table 8,
were autoclaved and filtered before spiking with nutrients or
inoculation with the test organism.  Autoclaving served  the func-
tion of resolubilizing the maximum amount of nutrients which were
bound in cellular material or detritus so that these nutrients
were available for growth during the assay.  The filtration pro-
cedure which followed autoclaving was simply a method for removing
residual cellular and detrital material which would interfere
with the electronic particle counter method of monitoring growth
of the test organisms.
    As indicated in Table 8, the results demonstrated that, with
only one exception, growth was limited by phosphorus in  the sam-
ples collected from South Lake Champlain on September 27 and
October 3, 1972.  The exception was the sample collected from
station 11 for which the assay indicated limitation by nitrogen.
While the samples collected from stations E and 189 B only re-
sponded to additions of phosphorus and nitrogen together, pro-
ductivity under such conditions could be limited by controlling
phosphorus.

    The results of the three EPA composite algal  assay samples
are summarized in Table 9.   Each of the samples  were autoclaved
and filtered prior to nutrient addition and inoculation with  the
test organism.
    As indicated by Table 9, the algal  assay results for all
three of the EPA samples indicated that primary  productivity
in the samples at the time of assay was limited  by phosphorus.
Maximum yields were not increased above control  values when only
nitrogen was added but yields were significantly increased above
control values by the addition of phosphorus alone.
    In summary, samples collected by Vermont and EPA which were
assayed by the bottle test using the green alga, Selenastrum
capricornutum, indicated that phosphorus was the nutrient which
was limiting to primary productivity in both South Lake Champlain
and Lake Champlain in its entirety.
    To a limited degree, the algal assay test gives a relative
comparison of potential productivity of different waters.  This
information is provided by the autoclaved-filtered control which
permits growth of the test organism to the extent of nutrient
availability in the lake water.
    In the algal assays of 206 lakes which the National Eutro-
phication Survey has conducted to date, the productivity range
of the controls was very large.  The most oligotrophic water
bodies yielded less than 0.1 mg/1 dry cell weight after 14 days

-------
                          32
 incubation while the richest water body yielded more than 248
 mg/1 after the same growth period.  Although the relationship
 between assay yield and trophic state has not been clearly
 defined, Miller (1974) has developed some tentative guidelines
 from his study of 49 American lakes.  Miller reported that (1)
 control yields ranging from 0-0.1 mg/1 corresponded to low
 productivity (oligotrophic) lakes, (2) control yields of 0.11 -
 0.8 mg/1 corresponded to moderate productivity (mesotrophic)
 lakes, (3) control  yields of 0.81 - 6.0 corresponded to moder-
 ately high productivity (eutrophic) lakes and (4) control yields
 of 6.1 - 20 corresponded to high productivity (eutrophic) lakes.
 The control yield values cited above represent lake conditions
where planktonic algae and not aquatic macrophytes dominate
 primary production.
    According to the above guidelines, the South Lake Champlain
 and Lake Champlain assay samples represented primarily moderate
 to moderately high productivity which corresponds to mesotrophic
or mildly eutrophic conditions.

V.  NUTRIENT LOADINGS
    A.  Introduction:
            One of the objectives  of the  National  Eutrophication Survey
        was to estimate nutrient inputs to  each  studied  lake and to
        determine the relative percentage of the total input which
        originated from point waste  sources.   To meet  this objective for
        Lake Champlain, a  sampling program  was initiated utilizing the
        volunteer services  of both the Vermont and New York National
        Guard organizations.
            National  Guard  sampling  teams from both States collected
        monthly samples from  pre-selected stream sites,  preserved the
        samples with  mercuric chloride, and shipped them to the  Pacific
        Northwest Environmental  Research  Laboratory in Con/all is, Oregon,
        for the analysis of nitrogen and  phosphorus constituents.  Sam-
        pling of Vermont streams was started in July,  1972, and  New
        York streams  were  started in November, 1972.
            Nutrient  concentrations  used  in loading calculations for New
        York streams  were  based on monthly  stream samples collected from
        November, 1972 through July, 1973.   For Vermont  streams  the sam-
        pling period  was July, 1972  through June, 1973.
            Stream flow estimates, which  are necessary to calculate total
        nutrient loads delivered to  a lake, were provided by the New York
        and New England District Offices  of the U.S. Geological  Survey.

-------
                              35
    U.S.G.S. also provided the majority of the data  on the  drainage
    areas of various stream systems.
        Phosphorus loadings were calculated for the  entire  Lake
    Champlain water body, which includes the South Lake area,  and
    separately for only that portion  of the lake designated as
    South Lake Champlain.
B.  Point Nutrient Sources:
    1.   Domestic -
            Tables 10 and 11 list domestic waste sources in the  Lake
        Champlain watershed from the  States of New York and Vermont
        respectively.  Also provided  in the Tables are (1)  the
        population served by each system, (2) the type of treatment,
        if any, (3) the estimated annual discharges  of total phosphorus
        and total nitrogen by each facility, (4) the name of the river
        or stream which ultimately delivers the nutrients to Lake
        Champlain, and (5) the approximate watercourse mileage of the
        discharges from Lake Champlain.  For each State, the discharges
        are listed in the order of river basin from the northern to
        southern end of the lake.
            The raw waste loadings of phosphorus and nitrogen to each
        facility were estimated on the basis of annual contributions
        of 3.2 pounds total phosphorus per capita (Hetling  and Carcich,
        1972) and 9.4 pounds of total nitrogen per capita.   For

-------
                    36
facilities providing either primary or primary plus secondary
treatment, the assumption was made that approximately 22% of
the total phosphorus (Bartsch, 1972) and 20% of the total
nitrogen was removed.  Therefore, if the facility provided
any type of treatment, the discharge was estimated to con-
tribute 2.5 pounds of total phosphorus per capita per year
and 7.5 pounds of total nitrogen per capita per year.  For
12 of the plants, nitrogen and phosphorus loads were esti-
mated on the basis of the analysis of composited effluent
samples.  The sampled plants are noted in Tables 10 and 11.
    Estimates of populations served in each community for
the State of New York were taken from the EPA STORET System
Municipal Waste Facilities Inventory and from State Inventory
Data provided by New York.  Population estimates for Vermont
communities were obtained directly from staff of the Vermont
Agency of Environmental Conservation.
    For both States, only those communities which were
partially or completely sewered and which had a direct
discharge of either treated or untreated wastes to surface
waters were considered.
    A total New York population of 84,773 was served by
systems discharging directly to surface waters in the Lake
Champlain drainage basin (Table 10).  On an annual basis
these discharges contributed 218,410 pounds of total

* Loading  values  were estimated on  basis of population served.  Estimates for untreated waste are 3.2 Ibs total
  P/capita/year and 9.4 Ibs  total N/capita/year and for treated wastes 2.5 Ibs total P/capita/year and 7.5 Ibs
  N/capita/year.

      phosphorus and  767,280 pounds of total nitrogen to the basin
      prior to the New York ban on phosphate laundry detergents.
      After the phosphate ban became effective (July 1, 1973), the
      New York phosphorus load would theoretically have been re-
      duced by 50% to approximately 109,000 pounds/year while the
      nitrogen load would have been unaffected.
         A total  Vermont population of 164,738 was served  by sys-
     tems discharging directly to surface waters in the Lake
     Champlain drainage  basin  (Table  11).  Annually,  these dis-
     charges  contributed an  estimated  444,410  pounds  of phos-
     phorus and 1,465,930 pounds  of nitrogen  to  the basin.
         Table 12  summarizes domestic  nutrient contributions  to
     Lake Champlain  by river basin  from  both New York and  Vermont.
     Also tabulated  separately  in Table  12  are total  pounds of
     phosphorus discharged from point  sources  within approximately
     25 river miles of Lake Champlain.   The total  point source
     phosphorus loading  in the basin from both states, prior to
     the New York phosphate ban, was 662,820 pounds of which 409,650
     pounds was discharged within 25 miles of  the  lake.  The total
     nitrogen loading in the basin from domestic sources in New
    York and  Vermont was 2,233,210 pounds per year.

        The only  major  industrial  nutrient source known to be
    discharging directly to  Lake Champlain is  the International

        Paper Company  (IPC)  facility  near  Ticonderoga,  New  York.
            Flow data  for the  mill  effluent  and  phosphorus  concentra-
        tions in the effluent  for all  of 1972  and  January through
        June of 1973 were supplied by the  New  York Department of
        Environmental  Conservation (see  Appendix F).   Based on these
        data, the average annual  loading to  South  Lake  Champlain
        from the mill  effluent was 24,090  pounds of total phosphorus.
            In discussions with staff members  of the  Vermont Agency of
        Environmental  Conservation it was  indicated there was a ques-
        tion concerning sample processing  prior  to phosphorus analysis--
        specifically whether or not the  samples  were filtered prior
        to analysis.   If the mill effluent samples were filtered  prior
        to analysis,  the phosphorus loading  of 24,090 pounds/year
        would be a low estimate and would represent total  dissolved
        phosphorus rather than total  phosphorus.
            No specific data were obtained for total  nitrogen loadings
        from the IPC  facility; therefore,  the  loading figure of 386,900
        pounds/year reported by T. W. Beak Consultants was  used as
        the estimated  contribution from IPC.

National Eutrophication Survey—accounting for 6,549  square miles
of the total Champlain land drainage of 7,744  square  miles, (2)
unsampled minor tributaries and immediate drainage  to Lake Champlain
which includes the remaining 1,195 square miles of  Lake  Champlain
drainage, (3) eight municipal  sewage effluents which  discharge
directly to Lake Champlain, (4) one industrial discharge directly
to Lake Champlain, and (5) phosphorus contributed directly to the
lake in precipitation.
    The data in Table 13 indicate that 81.0% of the total phos-
phorus load to Lake Champlain is input via the sampled tributary
streams.  The total phosphorus load carried by the sampled  tribu-
taries includes not only phosphorus from land runoff but also
that discharged from municipalities in treated and untreated
wastewater.  The problem is to determine the percentage of total
phosphorus load in the sampled tributary streams which originate
from the point waste sources.
    Because of the magnitude of the Champlain drainage basin,
and the fact that multiple waste sources are located on some
of the streams, it is not feasible to calculate specifically
the percentage of total phosphorus originating from each of
the point waste sources.  It is, however, possible to make some
reasonable estimates of the significance of point source input
to Lake Champlain.

                            46
      Table  14  summarizes  the  phosphorus  and  nitrogen  loads
  discharged  to  Lake  Champlain  by each  sampled  tributary and also
  shows the  total point  source  nutrient discharges to  each tributary
  system.  If the assumption were made  that all phosphorus discharged
  from point sources  to  tributaries in  the Lake Champlain Basin
  reached the lake, then 55% of the total tributary load and 52%
 of the total phosphorus load to Lake  Champlain could be attributable
 to point sources (domestic and industrial).  This would be the
 extreme case since it is  unlikely that all  of the phosphorus dis-
 charged from facilities located up to 82 river miles from Lake
 Champlain would ever reach the lake.  Impoundments  such as
 Arrowhead Lake and Lake Lamoille on  the  Lamoille River and  Water-
 bury  Reservoir in  the Winooski  basin would  permanently trap a
 portion  of  the  phosphorus  load carried by  the  stream.  Some of
 the remaining  phosphorus  would be  assimilated  by periphyton and
 macrophytic  plants  in the  stream or  adsorbed to  particulate mat-
 ter in the  stream  bed,  although  it can be argued that eventually
 the phosphorus  would move  downstream and reach Lake  Champlain.
    Point waste sources discharging  within 25  miles of Lake Cham-
 plain account for 63%  (433,740  Ibs) of  the  total phosphorus  orig-
 inating from point sources in the  entire drainage basin.  If  it
 is assumed that only  50% (293,400  Ibs/year)  of all the point
source phosphorus discharged to sampled  tributaries reached the

  lake, then point sources (municipal and industrial) would ac-
  count for approximately 27% of the tributary load and 30% of
  the total  phosphorus load to Lake Champlain.
      Taking a  different approach to estimate  the percentage of
  total  phosphorus  loading due to point  sources,  Table  15  presents
  the  average nutrient contribution  from eight tributary systems
  which  receive little or  no  point source nutrient  input.   The mean
  total  phosphorus contribution for  the  eight  tributary systems is
  106 pounds total phosphorus/square mile/year.  Multiplying this
  factor by the drainage area of sampled tributaries  (6,549
 square miles)  results in an estimated non-point loading of
 694,190 pounds P/year with the remaining loading of 374,630
 pounds attributable to point source discharges to the tributaries.
 By this estimate,  35% of the tributary  phosphorus load originates
 from point  sources  and, including direct municipal and industrial
 discharge to the lake, 36% of the total loading  to Lake  Champlain
 originates  from  point sources.   This  method agrees well with
 the  results obtained  by assuming that 50%  of  all  point source
 nutrients discharged  to tributaries  actually  reach the lake.
     In  summary,  using the conservative  estimate,  approximately 30$
 of the  total phosphorus  load  to  Lake  Champlain can be  attributed
 to New  York and  Vermont point waste sources.  This  estimate was
 based on conditions through June, 1973, prior to a  New York ban
on phosphate laundry  detergents.

     Effect of Phosphate Detergent Ban
         Phosphates in detergents account for approximately 50% of the
     total  phosphorus load in domestic wastewater.  In New York, a
     statewide ban on the sale of phosphate laundry detergents  became
     effective July 1, 1973.   Assuming that New York residents  in the
     Champ!ain drainage basin purchase and use  the non-phosphate
     detergents,  a 50% decrease  in wastewater phosphorus  loads  would
     be  expected.   The ban,  therefore, if effective, would decrease
     the phosphorus  load  to  Lake  Champlain and  the percentages  of the
     total  load attributed to point sources  as  indicated  in Table 16.
         Assuming  again that  50%  of all point source phosphorus  dis-
     charged to tributaries reaches  Lake  Champlain,  following the
     New  York  ban  the  total phosphorus  load  to  the  lake would decrease
     to  1,260,510  pounds per year,  of  which  30% would be  from point
     sources (municipal plus  industrial).
         If the State of Vermont  also  initiates a  phosphate ban,  the
     total phosphorus load to Lake Champlain would decrease to 1,133,960
    pounds per year, of which 18% would originate from point sources
     (municipal plus industrial).
D.  Annual  Total  Nitrogen Loadings to Lake Champlain:
        Table  17  lists the annual total nitrogen input to Lake
    Champlain  by  major sources including (1) tributaries  sampled
    by  the  National  Eutrophication Survey which account for 6,549
    square  miles  of the total Champlain land drainage of  7,744  square

    which  includes  the  remaining  1,195 square miles of  Champlain
    drainage,  (3)  eight municipal  sewage  discharges which  are
    direct  to  the  lake, (4)  one industrial discharge  direct  to  the
    lake,  and  (5)  nitrogen  contributed directly to  the  lake  in
    precipitation.
        The estimated  total  annual  nitrogen  loading  to  Lake  Champlain
    from all major sources  is  28,928,400  pounds.  Of  the  total, 75%
    is  input through the  sampled  tributary  streams.
        If it  is  assumed  that  all  nitrogen  discharged by  point  sources
    reaches Lake  Champlain, only  about 9% of the total  nitrogen input
    can be  attributed  to  these  sources.   The remaining  91% of the
    input results from land runoff and precipitation.  Point source
    nitrogen control from the  standpoint  of eutrophication would be
    pointless.
E.  South Lake Champlain Phosphorus Loading:
        Total  phosphorus  loadings to South  Lake Champlain are presented
    in Table 18.   South Lake tributaries  which were sampled by  the
    National Eutrophication Survey included 1,024 square  miles  or
    approximately 84% of the entire South Lake drainage area of
    1,216 square  miles.

estimated to be 197,350 pounds.   Of the total,  62% originates
from diffuse sources, whereas 38% originates from municipal  and
industrial  point sources which are subject to control.   Since
all domestic waste discharges are located within 25 miles  of the
lake, the assumption was made that 100% of the discharged  phos-
phorus eventually reached South Lake Champlain.
    Table 19 presents the annual phosphorus loading to South Lake
Champlain, by State, prior to the New York ban on phosphate
laundry detergents.  New York diffuse sources accounted for 27%
of the total input and Vermont diffuse sources about 35%.   Point
waste sources from New York and Vermont accounted for 31% and 7%
of the total input, respectively.  For all sources, New York con-
tributed 58% of the total and Vermont 42% of the total annual
phosphorus input.  The  International Paper Company, prior to the
New York ban, contributed 12% of  the total phosphorus to South
Lake Champlain.
    Table 20 summarizes  the  phosphorus contributions, by State,
after the New York phosphate laundry detergent  ban  (assuming the
ban  is 100% effective).   Under  this condition,  the  total load
to South lake would  be  reduced  to 179,200  pounds/year with  all
New  York sources  contributing 54% of the  total  load and all
Vermont  sources  contributing 46%.  With  the  New York  phosphate
ban  in effect,  the  International  Paper Company contribution
would  be 13%  of the  total  phosphorus  load.

        As an approximate check on the  reasonability of the  South  Lake
    phosphorus loading from diffuse sources,  the  average phosphorus
    loading from eight control  tributaries  (not receiving major
    point source discharges) to Lake Champlain was  106  pounds  P/
    square mile/year (see Table 15).
        This  factor, multiplied by the  total  South  Lake Champlain
    drainage  area of 1,216 square miles,  totals 128,900 Ibs  P/year;
    this is in very good agreement with the  diffuse source load in
    Table 18  of 123,310 Ibs P/year.
F.  Relationship Between Nutrient Loading and Trophic Condition:
        Based on phosphorus and nitrogen  loadings which have been
    reported  in the literature  for several  European and American
    lakes of  known trophic condition,  Vollenweider  (1973) estab-
    lished a  graphical  relationship between  annual  surface phos-
    phorus loadings, trophic conditions,  mean depths, and retention
    time of lakes.  While the validity  of the Vollenweider numbers
    has  not been completely established,  these numbers  are the best
    presently available and can be used as  an additional guideline
    to relate existing nutrient loadings  to  ideal loading rates
    and  trophic condition.
        Table 21  presents phosphorus loading  rates  to Lake Champlain
    for  point source phosphorus effluent  reductions ranging  from
    the  condition prior to the  New York ban  on phosphate laundry

-------
                         59
detergents to a situation where all  effluent phosphorus  from
Vermont and Mew York is reduced by 90% through treatment.   Prior
to the New York ban on phosphorus laundry detergents, the  esti-
                                                     2
mated loading rate to Lake Champlain was 0.53 grams/m  lake
surface/year which, following the NY ban, would have been  re-
                     2
duced to 0.51 grams/m /year.  If Vermont also imposed a ban on
phosphate detergents and the International Paper Company plant
reduced phosphorus discharges by 50%, the loading to Lake  Cham-
                       2
plain would be 0.45 g/m /year or approximately 85% of the  loading
prior to the New York ban.  If both states reduced all effluent
phosphorus by 80% or by 90% the loadings would be 0.40 and 0.39
g/m /year respectively.
    The loading data cited  in Table 21 are all calculated with
the assumption that 50% of  the total phosphorus discharged to
streams in the Champlain basin eventually reaches the lake.
That assumption is not unrealistic because 62% of all tribu-
tary point source phosphorus is discharged with 25 miles of
Lake Champlain.
    According  to Vollenweider's  relationship  between  phosphorus
loading, mean  depth, detention  time and  hydraulic residence  time,
                     2
a loading of 0.51 g/m /year corresponds  to  the so-called  "dan-
gerous" loading level which is  the cut  off  between a  eutrophic

-------
                        60
and mesotrophic condition.  If the loading were reduced to 0.40
   2
g/m /year according to Vollenweider, Lake Champlain would be
well within the mesotrophic zone of the loading relationship.
    Loading relationships for South Lake Champlain for various
conditions of effluent phosphorus reductions are presented in
Table 22.  South Lake Champlain phosphorus loading rates are
about three times higher than for all  of Lake Champlain.  Prior
to the New York ban on phosphate laundry detergents, the loading
                 2
rate was 1.57 g/m /year which would be expected to decrease to
        P
1.43 g/m /year following the New York ban.  If Vermont imposed
a similar ban and the International Paper Company reduced its
phosphorus discharge by 50% the phosphorus loading rate would
be 1.28 g/m /year.  An 80% reduction by all point source dis-
charges to South Lake Champlain or its tributaries would re-
duce the loading to 1.10 g/m2/year while a 90% effluent phos-
                                                      2
phorus reduction would result in a loading of 1.04 g/m /year.
    According to the Vollenweider relationship, the "dangerous"
                                                             2
phosphorus loading level for South Lake Champlain is 0.85 g/m /
year.  This level could not be met even if all effluent phos-
phorus were removed from the South Lake Champlain drainage
basin.

        Memorandum

           The Record
187
                DATE:  February 1, 1973
n-»o>-  :    Jac!: •'• Sakstattar
           Chief, National Eutrophication Survey Program

-UBJECT:    Lake Champlain Algal  Assay Samples  Collected by Vermont

                This memo refers only to those ten samples collected from Lake
           Champlain by Vermont (and T.  W.  Beak Consultants) September 27, 1972
           and October 3, 1972.   After collection the samples wera frozen and
           sent air freight to Corvallis, Oregon arriving on October 6, 1972.
           Upon receipt the samples were placed in a refrigerator.  On October
           12 processing of the samples  began, i.e. they were split into equal
           portions and each portion was--either filtered (0.45 micron pore
           size) or autoclaved and then  filtered.  This is the point at which
           the improper amount of mercuric  chloride preservative was added.

                The question will probably  arise as to why we bothered to pre-
           serve the samples anyway after they had been in a relatively un-
           preserved state (except for cooling which certainly retards
           biological activity and is an accepted preservative method for
           short periods) from October 6 to October 12.  The reply to the question
           is that CLS (Consolidated Laboratory Services) provides analytical
           services to the entire laboratory on a first come - first serve basis.
           Samples submitted for analysis  are not refrigerated by CLS and since
           there is no guarantee that the  analytical work will be done immediately,
           it is standard procedure to preserve the samples with mercuric
           chloride (40 mg/1).

                After the fiIteration or autoclaving-fiIteration, aliquots were
           taken  from each portion of each  sample  to  be preserved with mercuric
           chloride and sent to CLS for analysis.   My algal  assay staff  inadvertently
           picked up the wrong container of mercuric  chloride  to  do  the  preserving.
           The net  result was that instead of preserving  at a  concentration  of
           40 mg/1  mercuric  chloride, each aliquot  contained only 0.04 mg/1  mercuric
           chloride which was insufficient to prevent biological  activity.   The
           improperly preserved samples were sent to  CLS  on October  12 and analyses
           did not  begin  until October  25.

     The question has also been raised as to why analyses were not
done on the raw samples before autoclaving-f literati on or filteration.
At the time these samoles were received, my staff indicated that thsra
was not enough sample volume to get an analysis for each raw sample,
as well as after each treatment.  Faced with the choice of either
analyzing before or after the autoclaving-f literati on or filteration  •
process, they chose to analyze after the treatments but before the
samples were set up for the algal assay so that the chemistry in
the water just prior to the assay would be known.
