                           I.  INTRODUCTION
     The cranberry industry, as well as other fruit producers, has
over the past several decades, become increasingly dependent upon the
use of chemically formulated pesticides to control insect damage, and
thus increase its overall crop production.  As a result of this in-
crease in pesticide use and associated hazards, the Environmental
Protection Agency (EPA) has, as part of an ongoing National  Pesticide
Use Observation Program, surveyed several agricultural sections of
the Country.   In this instance, southeastern Massachusetts was selec-
ted to represent a major fruit producing area using Class I* pesti-
cides to control insects.

     Two studies have been conducted by the National Enforcement In-
vestigations Center (NEIC) on cranberry bogs in Wareham, Massachusetts
[Figure 1].   The first took place in the fall of 1977 with the follow-
ing objectives:   to determine if pesticide residues were present in
cranberry bogs following a season of treatment with insecticides; and
to determine the extent and effect, if any, of pesticide transloca-
tion from the cranberry bogs to adjacent wetlands and receiving waters.
The results of that study were published in March 19781.  The second
investigation, discussed in this report, was conducted in the spring
of 1978 prior to and during the season's first pesticide application.
The primary objective was to determine if the field application of
pesticide on cranberry bogs was performed consistent with registered
labeling, FIFRA** regulations, and appropriate State codes.

     The second use observation study was from June 10 to 19, 1978.
NEIC personnel observed the application of parathion to control fruit
    Classes defined in FIFRA. **  FIFRA:
    Federal Insecticide, Fungicide, and Rodenticide Act,
    PL94-140, Nov. 1975.

worms on two 9.75 hectare (19.7 acre) cranberry bogs.   Pesticide was
applied on one bog by a low-gallonage sprinkler system, and a second
bog was sprayed aerially by a helicopter.

     Environmental quality information at each study site was obtained
prior to and following the application of pesticide.   Water,  sedi-
ment, soil and biological samples were collected from several sites
for pesticide analyses.   In addition, various types of spray drift
cards were used to characterize pesticide drift beyond the target
area.  This allowed comparison of pesticide levels in the environment
before and after application, and supplied relevant information on
application techniques.

     On-site studies were made to determine,  (a) if the licensed*
applicators read and understood the product labels, (b) if they
followed the directions and precautions on the label,  (c) if they
properly cleaned and maintained application and protective equipment,
(d) if pesticides were stored properly, and (e) if the disposal of
excess pesticides and containers was proper and safe.
*  Pesticide applicators in Massachusetts are licensed to apply pesti-
   cides but not certified to handle "restricted use" insecticides.

-------
                     II.  SUMMARY AND CONCLUSIONS
     At the request of EPA Region I, a pesticide use study was con-
ducted by NEIC from June 10 to 19, 1978 on two cranberry bogs in
Wareham, Massachusetts.  The purpose of the study was to observe and
evaluate the activities associated with aerial and sprinkler applica-
tions of PARATHION E-8* to control an infestation of Sparganothis
fruitworm.  The following findings resulted from the NEIC study.

     PARATHION E-8 is a "restricted use" pesticide to be sold to, and
used only by, certified applicators.  Massachusetts at this time has
no certification program; therefore, the use of PARATHION E-8 by uncer-
tified applicators in Massachusetts^during this study was not consistent
with Federal regulations.  This did not, however, constitute a violation
of State regulations.

     Although certain chlorinated hydrocarbon pesticides are no longer
used on cranberry bogs in Massachusetts to control infestations of
insects, their persistence is evident.   Dieldrin, DDT and several
other related compounds were found in soil and sediment samples during
this study.  Further investigations should be conducted to determine
if chlorinated hydrocarbon pesticides occur in the fruit.

     Both aerial and sprinkler applications were conducted efficiently.
Every effort was made to contain the pesticide within the bogs.  Safety
procedures specified on the label were closely followed by the licensed
applicators during handling and application of the pesticide.  Approaches
to the sprayed areas were well posted with adequate poison warning
signs.

     Despite precautions by the applicators, it was impossible to
avoid contaminating the drainage water in the irrigation ditches
surrounding and traversing the study sites.

     Analytical results of water samples indicated that irrigation
water was not impounded in the irrigation ditches for adequate lengths
of time after spraying (96 hrs or more).   One hour after application
of parathion to the Pierceville bog, discharging irrigation ditch
water contained concentrations of ethyl parathion ranging from 130-150
ug/1 over a one-half hour sampling period.   This contaminated water
was being discharged into the Sippican River and would eventually
become available to commercially important marine species in the re-
ceiving estuary.

     Although parathion uptake was determined in two samples of the
fish exposed _in situ, no harm or adverse effects were observed in the
natural aquatic biota following the insecticide application.

     The spray drift cards were effective in determining the pesti-
cide drift patterns during both applications.  The sprinkler method
of pesticide application appeared to produce less spray drift than
the aerial application.

     Insect counts following the application of PARATHION E-8 showed
the treatment to be 90% effective against fruitworm infestation.

     New disposal  regulations for used containers of toxic materials
have yet to be promulgated under the January 31, 1978 Massachusetts
Pesticide Control  Act.   Therefore, regulations under a preceding Act
remain in effect.   The present law recommends that used containers of
toxic materials be triple-rinsed, crushed and disposed of in approved
sites.   Presently there are no disposal sites in southern Massachusetts

-------
approved by the Department of Environmental  Quality Enforcement.   The
toxic containers used in this application were rinsed,  crushed and
disposed of in a pit in a local landfill.

-------
                           III.   BACKGROUND
     Since the passage of the Federal Insecticide, Fungicide,  and
Rodenticide Act (FIFRA), in 1972, and its Amendments in 1975,  severe
restrictions have been imposed on the use of pesticides and on appli-
cators.  The Act makes it illegal to use a pesticide if it is  not
labeled for use with a specific pest.  Also the Act classifies pesti-
cides for restricted and non-restricted use.  Parathion is categorized
by FIFRA for restricted use.   According to Federal regulations, there-
fore, it is necessary to have a certified private applicator license
for applying parathion to land owned or rented by the applicator, or
applying it in trade for services rendered.   Furthermore, a certified
commercial applicator license is required for someone who applies
parathion commercially.   Massachusetts does not have a certification
program under its 1978 Pesticide Control Act; therefore, any "restricted
use" pesticide applicator in the State violates Federal, but not State,
regulations.  Many of the cranberry growers in Massachusetts have profes-
sional applicators to do their spraying if a pest control advisor
indicates the necessity.

     Presently, two methods are used to apply pesticides to a cran-
berry bog:  through a sprinkler system or by airplane.  Bogs equipped
with sprinklers have a multi-use system which also provides for irri-
gation and fertilization.  More remote bogs that maintain irrigation
ditches for water supplies use aerial application for fertilizer or
pesticide.

-------
                     IV.  DESCRIPTION OF THE STUDY
     The cranberry bogs selected for the study were identified by the
grower as the north piece of the Tremont Bog and the middle portion
of the Pierceville Bog.  Both sites are in Wareham, Massachusetts
[Figures 2 and 3] and consist of approximately 9.75 hectares (19.7
acres) each.   The Pierceville Stream flows through the middle of the
Tremont Bog and contributes to the reservoir supplying the Pierceville
Bog.   A spring adjacent to the Pierceville Bog also provides irrigation
water.  The Pierceville Stream joins the east branch of the Sippican
River, which eventually discharges into Buzzards Bay south of the
Cape Cod Canal [Figure 1].  Water for flooding, sprinkler irrigation,
and pesticide applications through the sprinkler system is obtained
from the Pierceville Stream.

     Background information was collected on each bog prior to pesti-
cide application.   To determine possible pesticide contamination from
upstream locations, pre-application samples of water and sediments
were collected from the reservoir upstream of the Tremont Bog (Station
01) and the water intake to the Pierceville Bog (Station 14).  To
assess the presence of pesticide residues on the study sites, water
and sediment samples were collected from the Pierceville Stream (Sta-
tion 04), and soil samples were collected on and adjacent to both
bogs (Stations 06-13 and 15,  16, 17, 18, 19, 22, 23, 25).   At the
southern extremity of the Tremont Bog (Station 05) and the discharge
sluice gate at Pierceville Bog (Station 20), samples of water and
sediment were collected to determine pesticide translocation from the
bogs.   Following the initial  sampling, daily samples were collected
and i_n situ water quality data were obtained from the water intakes
and discharges on both application sites until the completion of the
investigation [Tables 1 and 2].

   On-site elevations required the elimination  of several  sampling
   stations.   The original  station numbering system remained,  which
   accounts for absent station numbers  on several  tables.

     The sampling procedure following the pesticide application was
similar to that used for pre-application data collection except that,
just prior to application, spray cards were placed close to the soil
sampling stations at both sites.

     During the spraying operations NEIC and Region I personnel eval-
uated the mixing, loading, and application procedure used at each
cranberry bog.

     Throughout the study, channel catfish, Ictalurus punctatus
(Rafinesque), were held in submerged cages to monitor acute physio-
logical effects of pesticide exposure.  In Tremont Bog these were
placed in the storage reservoir (Station 01), in Pierceville Stream
upstream of the first sluice gate (Station 04), and at the third
sluice gate in the lower bog (Station 05).  Two stations were located
on the Pierceville Bog:  at the water intake (Station 14) and at the
water discharge (Station 20).

                         V.   USE OBSERVATIONS
PESTICIDE APPLICATION METHODS

     A major distinctive feature associated with the cranberry bogs
under investigation was the method adopted to apply the pesticide.
Sprinklers were used to dispense the chemical on the Tremont Bog
which entailed direct injection into the system; while the applica-
tion on the Pierceville Bog involved the use of a nurse rig to trans-
fer dilution water and pesticide into helicopter tanks for subsequent
aerial spraying.   The only practices common to both sites were the
similar methods for detecting pest infestations, impounding irrigation
waters, use of parathion E-8, and the posting of the properties.

     In the cranberry producing area of Massachusetts, the growers
receive agricultural information, advice, counseling, and other assis-
tance from the University of Massachusetts Cranberry Experiment Station
located in East Wareham.  This Station issues a yearly chart detailing
the general schedule for insect control.2  This publication provides
cautions and notes relating to pesticides or other treatments applied
to the bog.  The publication emphasizes the necessity to apply pesticides
in such a manner as to prevent contamination of streams, ponds and
public ways and confine irrigation ditch water as long as possible
after application.  Furthermore, it strongly suggests that insecticides
be applied only if damaging numbers of insects are present.2  Finally,
the need to read and follow all directions and safety precautions
printed on pesticide labels is strongly emphasized.  Informative pub-
lications such as these have not only contributed to the production
of higher cranberry yields, but have made the growers more cognizant
of the dangers associated with pesticide use.

-------
                                                                      15
     On June 10, the consulting entomologist estimated that the harm-
ful insect population density on each bog was approaching infestation
level and pesticide application was essential when the weather per-
mitted.  The injurious insects infesting the bogs were Sparganothis
fruitworms.   The Cranberry Experiment Station suggested that parathion
be used as a control agent and that it be applied at the rate of 0.18
kg/ha (1 Ib/acre) on the Tremont Bog and 0.14 kg/ha (0.75 Ib/acre)
on the Pierceville Bog.


SPRINKLER APPLICATION

     The Tremont Bog was selected for the initial spraying which was
scheduled for the evening of June 12.  In preparation, the bog owner
tested the sprinkler system and adjusted or replaced faulty spray
heads.  All  access roads and immediate areas were posted with appro-
priate poison warning signs.  Moderately strong winds on the selected
evening and on several following evenings prevented spraying.   How-
ever, on the evening of June 15, weather conditions were proper for
spraying operations.  The wind was calm, the air temperature was 18°C
(65 °F) and the relative humidity was 52%.

     Prior to spraying the field, EPA obtained water samples from the
upstream reservoir (Station 01) and the irrigation discharge (Station
05).   Also,  approximately 15 minutes before application, the survey
team placed spray cards, consisting of Linagraph (10 x 25 cm) Kromcote
and Thermofax (10 x 12.5 cm) cards fastened horizontally to cardboard,
around the field perimeter at Stations 06 to 11.

     Team members were stationed at strategic locations near the field
to observe the application.   Other observers were located near the
pumping area to observe mixing and injection of pesticide into the
system.  All team members were wearing appropriate safety equipment
*  EPA Reg. No. 148-475 (Pierceville Bog); EPA Reg. No. 8590-204
   (Tremont Bog).

                                                                      16
as outlined on the pesticide label [Appendix A] and in the NEIC Pro-
ject Plan.

     Pesticides, such as PARATHION E-8, must remain on the plant for
several minutes to be effective.   When using a sprinkler system,
caution must be used to hold the application time to a practical min-
imum to prevent washing of the pesticide from the plant.3  The low-
gallonage systems used on these bogs applied water at a rate of 170
liters (45 gal) per minute; hence ten minutes proved a satisfactory
time to obtain complete wetting of the cranberry plants.

     After the licensed applicator determined the dispersion effect
of the sprinkler heads, he injected the pesticide into the system.
To do this, a large bucket was used for mixing and injecting the
pesticide.   Two hoses were connected to small gate valves in the
pump, one on the discharge side and the other on the suction side.
The discharge hose was used to fill the bucket and the suction hose
to draw the mixed pesticide from the bucket into the pump and sub-
sequently into the irrigation system.  The application commenced at
1945 hours and was completed at 2000 hours.

     During the spraying operation, the applicator followed the label
requirements for mixing and safety which resulted in a clean and effi-
cient operation.  However, spray did enter the Pierceville Stream
along its entire length in the upper Tremont Bog.  The stream had
been partially dammed pending the application, but because the Com-
pany did not wish to flood the bog at this growth stage, a small
volume of water was passing over the lower sluice gate, which was
contrary to the 96-hour holding time.  Additionally, some spray did
extend outside the bog (3 to 4 m) in some areas but fell harmlessly
onto the surrounding road and adjacent bogs.  Negligible drift was
observed.

                                                                      17
     Shortly after spraying ceased, spray-drift cards were retrieved.
Further sampling was postponed until the following morning because of
darkness.

     Post-application sampling on Tremont Bog was completed on June
16.  Water and sediment samples were collected at Stations 01, 04,
and 05.  The caged fish (Stations 04 and 05) and other aquatic fauna
in irrigation ditches were examined and no ill effects from the pesti-
cide were visually noted during this time.   Soil samples were obtained
at Stations 06 to 13.
AERIAL APPLICATION

     The morning of June 17 was selected for the aerial application
of parathion on approximately twenty acres (9.75/ha) of the Pierceville
Bog.   On June 16, the Cranberry Experiment Station issued a warning
that growers should prepare for a possible frost that night or during
the early morning hours of June 17.   Because the section of Pierceville
Bog selected for spraying was not equipped with a sprinkler system,
it was necessary for the Company to increase irrigation water level
with flow from the adjacent reservoir.   When EPA observers arrived at
the site on the morning of June 17,  the ditch water level had been
raised so that it caused fog just above the bog, thus providing pro-
tection against frost damage.  This fog was allowed to dissipate before
spraying began and the excess water in the ditches was allowed to
drain off the bog into the Sippican River.  Water samples were obtained
at Stations 14 and 20 before the discharge sluice gate was opened.  A
small amount of water was still draining from the bog both during and
after the spraying operation.

     Approximately 15 minutes before spraying operations began, the
survey team placed drift cards, Kromcote, Linagraph and Thermofax
cards which were fastened horizontally to cardboard, on and around
the field perimeter at Stations 15-19, 22, 23, and 25.  Two drift

                                                                      18
cards were also placed about 300 m east on County Road adjacent to a
residential area (Stations 21, 26).

     At 0430 hours on June 17 the day of the scheduled pesticide appli-
cation, the nurse rig arrived at the mixing and loading site adjacent
to the bog.  The nurse rig consisted of a large flatbed truck carrying
a 3 m fiberglass sphere containing the water supply and two 210-liter
(55-gal) drums containing the parathion, attached horizontally.  The
exposed ends of the drums displayed the PARATHION E-8 label [Figure 4].

     The pesticide loading apparatus used by the applicator was an
open system consisting of two nozzled rubber hoses; one connected
from the water supply and the other from the pesticide drum to the
helicopter spray tank.  Each liquid was metered to the helicopter
tank and mixed simultaneously.  During the loading operation, no
water or pesticide solution was spilled at the site.   Three appli-
cator employees comprised the team performing the loading operation,
but only one member loaded the helicopter spray tank.  All employees,
including the pilot, wore proper safety equipment consisting of hat,
long-sleeve coveralls, boots, gloves, glasses and respirator.  The
workers appeared to be very conscientious, neat and familiar with
their jobs.

     The application began at 0530 hours and was completed at 0600
hours.   The wind was calm, air temperature was 7.0 °C (45 °F) and the
relative humidity was 93 percent.

     The aircraft used was a Bell  47 63B2 helicopter.  The 7.3 m spray
boom was equipped with 19 No. 08 nozzles evenly spaced [Figure 5].
Boom pressure was set at 2.5 to 2.8 kg/cm2 (36-40 psi).   The aircraft
operated at a speed of 61 to 64 km/hr (38 to 40 mph)  approximately
3.6 m (12 ft) above the bog surface [Figure 6].  The  pilot made passes
southwest and northeast, paralleling the main irrigation ditches and

then trimmed the edges and more difficult indentations.   It was im-
possible for the pilot to avoid spraying pesticides into the irriga-
tion system because of bog configuration.

     Two tank loads of pesticide mix were needed to complete the operation.
Before leaving for another bog, the pilot filled the pesticide tank
on the helicopter with water and dispensed it over the site.

     Shortly after spraying operations ceased, the spray cards were
retrieved from the outside perimeter of the bog, and further sampling
was delayed for one hour to allow the moisture to dissipate.

     When sampling resumed, water and sediment samples were collected
at Station 14 (intake), and a sediment and three water samples, at 15
minute intervals, were collected at the water discharge sluice gate
(Station 20).   Caged fish examined at these stations did not appear
to have been affected by the pesticide.  The remaining spray drift
devices were gathered from the interior of the bog and the post-ap-
plication field work was completed when soil samples were taken at
Stations 15-19, 22, 23 and 25.  To determine if irrigation water con-
taining parathion had been discharged from the Pierceville Bog, a
water sample was collected 2-1/2 hours after application from the
Sippican River (Station 30) about a quarter mile downstream from the
application site at Pierceville Road bridge.
CLEANUP

     The helicopter used in the aerial application was not observed
during the cleanup operation.   However, an officer of the contracted
firm stated that, at the end of the day, the helicopter spray tanks
are filled with water and flushed over a previously treated area.
This method of cleaning the spray tanks is normal following parathion
applications.

                                                                      21
     At the Tremont Bog, discussed earlier,  the method used for
cleanup of the spinkler apparatus after pesticide application was to
flush the system with clean water for several  minutes.


CONTAINER DISPOSAL

     To date, disposal regulations for used  toxic material  containers
have not been promulgated under the January  31, 1978 Massachusetts
Pesticide Control Act.  Therefore, the regulations established under
the preceding Act remain in effect.   For used  containers of toxic
materials, the existing law recommends that  they be triple-rinsed,
crushed and disposed of in an approved site.   Presently, there are no
disposal sites in southern Massachusetts approved by the Department
of Environmental Quality Enforcement.   The toxic containers used in
this application were rinsed, crushed and placed in a pit in a
local landfill.
EFFECT OF PESTICIDE

     Insect counts conducted by the company entomologist several days
following the PARATHION E-8 application on both sites indicated that
the treatment was 90% effective in controlling the fruitworm infesta-
tion, and therefore was considered acceptable.

-------
                      VI.   DISCUSSION AND RESULTS
     During the period of this pesticide use observation study a total
of eighty-eighty (88) samples were collected from both sites.   Thirty-
two (32) of these samples were selected to assess the effects  of the
pesticide applications on the surrounding environment.

     The analytical results from each site are discussed separately
below and in the sequence in which the pesticide would probably
follow in passing through the local ecosystem.  The spray drift cards
were examined to provide immediate indications of likely drift settle-
ment.   From this examination, site selections were determined  for later
soil sample analyses.  Translocation of the pesticide will be  discussed
relative to its presence in water, stream bottom sediments and uptake
by fish.   [See Appendix C for Analytical Methods].

     During the analyses of soil and sediment samples, traces  of chlor-
inated hydrocarbon pesticides were also detected.  The locations and
relative persistence will be discussed later.
TREMONT BOG STUDY AREA

     Microscopic examination of drift cards exposed on the boundary of the
study site revealed that pesticide droplets drifted beyond the north side
of the treated field (Station 10).  Chemical analysis of the thermofax por-
tion of the card array revealed that 0.1 ug ethyl parathion spray drift
contacted the card surface.   No methyl parathion was detected* [Table 3].
*  Methyl parathion was not applied to the cranberry bogs during the
   PARATHION E-8 applications.  However,  during chemical analyses of
   samples, methyl parathion is often detected with ethyl parathion
   and is considered an impurity in the pesticide formulation.

     Analyses of soil samples collected prior to the pesticide appli-
cation (Stations 06, 10) revealed no traces of ethyl parathion.   A
soil sample from Station 10 (north of the bog) collected after the
application contained ethyl parathion at a concentration of 0.01
ug/g.  No additional post application soil samples were committed to
analyses [Table 3].   This indicated spray drift beyond the north  edge
of the bog.

     Several days of adverse weather delayed parathion application to
this bog and for this reason more water samples were collected than
were scheduled.   During this delay six water samples were obtained at
the reference station (01) and six at the point where the Pierceville
Stream discharged from the bog (Station 05).  Water samples from
Station 05 collected on June 12 and 13 contained ethyl parathion  at
concentrations of 0.5 and 0.3 ug/1, respectively.   Samples obtained
from reference Station 01 and the bog discharge Station 05 on the
evening of June 15,  just before the spraying operation, contained
traces of ethyl  parathion [Table 4].   The source of parathion in
Pierceville Stream and the upstream reservoir prior to the June 15,
1978 pesticide application was not determined.

     Analyses of post-application water samples showed an increase in
parathion levels for both the reference station (01) and the station
downstream of the treated area (05).   Water samples from Station  01
collected at 12 and 36 hours after the application contained 0.4  and
8.4 ug/1 of ethyl parathion, respectively [Table 4].  This implies
that intensive pesticide use was occurring on bogs upstream of the
reservoir.   At approximately the same time intervals, water samples
collected at the bog discharge (Station 05) contained levels of ethyl
parathion ranging from 8.4 to 9.0 ug/1.  A single water sample col-
lected June 16,  1978 just downstream from the treated section of  the
bog (Station 04) contained 2.3 ug/1 ethyl parathion.  With such a
widespread distribution of parathion throughout the water system, it

is not possible to determine the contribution attributable to this
particular application.

     Sediment samples were obtained from three locations near the
study site prior to and following the pesticide application.   The
analytical results for Stations 04 and 05 showed neither methyl or
ethyl parathion contaminated the stream bed [Table 3].

     A record of the water quality and fish conditions throughout the
exposure time is contained in Tables 5 and 6.   [See Appendix 0 for
Massachusetts Water Quality Standards].   Station 04 on the Tremont
Bog was not monitored as closely since it was bracketed by Station 01
upstream and Station 05 downstream.

     The water supply sources of each application site caused dis-
tinctive ranges for the water quality parameters measured.  The large
reservoir supplying Tremont Bog caused the water temperature to be
higher and the pH range at Station 01 to be slightly lower in com-
parison to the spring-fed water supply flowing past Stations 14 and
20 at the Pierceville site.  Heavy growth of aquatic plants in the
main irrigation ditches caused the dissolved oxygen (DO) content on
both bogs to remain high during the daytime sampling.   Most of the 00
readings were well above 100% saturation.

     On June 18, 1978 the J_n situ exposed fish were retrieved, frozen
and returned to the NEIC laboratory for chemical analyses of pesti-
cide uptake.   Fish from Station 01 (Reference) and Station 04, im-
mediately downstream from the treated area, were the only samples
analyzed.  An ethyl parathion concentration of 2.0 M9/9 was detected
in fish from the reference site (station 01) and 1.4 ug/g from the
fish exposed at Station 04.  No methyl parathion was evident in either
sample [Table 3].   There was no indication of harm or stress to the
local aquatic biota resulting from this application.

PIERCEVILLE BOG STUDY AREA

     The spray drift cards exposed on and around this study site were
retrieved shortly after the pesticide application to prevent possible
interference from local mist conditions.   Seven of the ten sets of
cards examined on-site appeared to have droplets from the aerial appli-
cation.   Microscopic examination later confirmed this.   Chemical an-
alysis for parathion on five of the contaminated Thermofax cards
showed that heavier and more consistent overspray occurred along the
southern border of the treated bog.  This was attributed to the bog
irregularities in this sector which apparently caused spray overlap
by the aerial applicator.   Ethyl parathion on the Thermofax portion
of cards placed around the southern boundary ranged from 2.0 to 4.2
ug/card [Table 7].  The Thermofax cards at Stations 23 and 25,  lo-
cated on the bog, received ethyl parathion dosages of 400 and 140
ug/card, respectively; methyl parathion (a formulation impurity) was
detected at 0.5 and 0.2 ug/card.  Drift cards at Stations 21 and 26
located east of the site on County Road received no spray or droplet
drift from the aerial application.

     Four of the six soil  samples collected on the southern boundary
of the bog (Stations 17, 18, 19, 22) prior to the pesticide applica-
tion were chemically analyzed.   Station 19 soil samples, south of the
bog, contained 0.03 ug/g ethyl  parathion which could not be explained.
Analyses of five post-application soil samples, also on the southern
boundary, indicated no ethyl parathion present.  Two post-application
soil samples were obtained from the bog (Station 23 and 25) and the
results of their analyses  showed a concentration of 0.06 ug/g of ethyl
parathion in only one, Station 25.  None of the above analyzed soil
samples contained traces of the impurity, methyl parathion [Table 7].

     Fifteen water samples were collected from the Pierceville study
site; ten before and five  following the pesticide application.   All

water samples were collected from a supply tributary to the bog
(Station 14) and from an irrigation ditch discharging from the bog
(Station 20) with the exception of one water sample obtained at the
conclusion of the study from the Sippican River (Station 30).   All
pre-application samples contained traces of ethyl parathion from
unknown sources [Table 4].   A series of water samples taken at
Station 20 showed that ethyl parathion steadily decreased in the
irrigation ditch water [Table 4].   Continued drainage from the bog
during this sampling period was the probable cause of this decrease
in concentration of pesticide.   The intake water at Station 14 still
contained a measurable concentration two hours following application
(0.4 |jg/l).  Further indication that the discharge irrigation ditch
at Station 20 was grossly contaminated was the presence of methyl
parathion in the samples.   A water sample from the Sippican River
about a quarter mile downstream from the Pierceville Bog discharge
contained an ethyl  parathion concentration of 37 ug/1 and a methyl
parathion concentration of 0.1  ug/1.  Since there was no apparent
damage resulting from this pesticide concentration, the Massachusetts
Water Quality Standards were not violated [Appendix D].  Whether this
level is related to the application on the Pierceville Bog or the
results of contamination from upstream bog discharges can only be
speculated.

     Sediment samples were obtained from two locations on the study
site before and following the pesticide application.   Results of
chemical analysis of sediment from Stations 14 and 20 showed that no
methyl or ethyl parathion was found in the stream bed at these loca-
tions [Table 7].

     No indication of harm or stress to the indigenous aquatic biota
or to caged fish was visually evident resulting from this application.
Therefore,  the jjn situ exposed fish retrieved on June 19, 1978 from
Stations 14 and 20 were not analyzed for pesticide uptake.  A record
of the water quality and fish condition throughout the exposure time
is contained in Tables 3 and 4.

CHLORINATED HYDROCARBON PESTICIDES
     Chemical analyses of soil and sediment collected during the
June 1978 pesticide study at Tremont and Pierceville bogs,  revealed
the presence of chlorinated pesticides.   These pesticides were not
detected in the October 1977 study done by EPA.   Analyses of the
October 1977 samples were completed using a gas chromatograph
equipped with an alkali flame ionization detector (AFID), which was
specific for phosphorus and nitrogen compounds,  but did not respond
to chlorinated compounds.   During the June 1978 study, soil and
sediment samples were analyzed using an AFID and an electron capture
(EC) detector.   The EC detector is extremely sensitive to chlorinated
compounds, and therefore the chlorinated hydrocarbon pesticides
present were detected.  The chlorinated hydrocarbon compounds
detected were p,p', DDE; o,p', ODD, p.p1, ODD, Dieldrin and Technical
DDT [Table 8].

     Because organochloride pesticides were detected incidently and
not as an objective of the pesticide use observation study, the full
significance of their presence, concentration and distribution on and
off the study sites cannot be determined fully.

     Of the sixteen soil samples from the Tremont study site, two of
the three from the bog perimeter contained traces of chlorinated com-
pounds.  At this time, there is no analytical evidence that chlori-
nated hydrocarbon pesticides are present in the bog soil.  The soil
samples obtained off the bog [Station 10] contained the following
concentrations of organochloride pesticides: p,p', DDE (<0.01 and
0.20 ug/g), o,p', ODD (<0.01 and 0.40 ug/g), p.p', ODD (<0.01 and
1.5 ug/g). Dieldrin and DDT (<0.01 ug/g) [Table 8].  The same
chlorinated compounds, except Technical  DDT, were detected  in sedi-
ment from two stations (04 and 05) located in the Pierceville Stream
which flows through the Tremont study site.

     Two soil samples obtained from the bog sector of the Pierceville
bog and analyzed for chlorinated pesticide compounds.  One contained
a detectable amount of Dieldrin (0.03 ug/g).   The remaining compounds
were present in less than detectable amounts  in both samples.   Soil
samples from the perimeter of the bog contained detectable concentra-
tions of p, p', DOE Dieldrin and Technical DDT.   Four sediment samples
collected from two stations (14 and 20) in the irrigation ditches con-
tained detectable concentrations of all five  chlorinated hydrocarbon
pesticides [Table 8].
     In 1975 the national average for Dieldrin in crop soil  was
0.03 |jg/g.  This average is exceeded on the Pierceville study site
both off the bog (<0.0.1-72 ug/g) and in the irrigation ditch sediment
(<0.01-0.09 ug/g) [Table 8].   Records are not available to determine
whether the insecticide was applied as Dieldrin or as Aldrin and con-
verted to epoxide dieldrin by air, bacteria or plant and animal en-
zymes.6  The average time required for 95 percent "breakdown" of
dieldrin is estimated at 9.7 years.4

     The concentration of Technical DOT in the soil surrounding the
Pierceville study site and in sediment from the irrigation ditch ex-
ceeded amounts reported by the National Soils Monitoring Program in
1969 for soils in Illinois.5  Technical DDT was reported in a range
of 0.06-0.12 ug/g.   Residues of Technical DDT found on the Pierceville
study site were <0.01-0.09 ug/g for the sediment and <0.01-1.1 ug/g
for soils adjacent to the study site.  It is estimated that 11 years
is needed to attain 95 percent "breakdown" of DDT in soil.6

     The above analytical results lend credence to the claim that
organochlorine insecticides persist in the environment.  Application
records of chlorinated compounds are not readily available for these
particular study sites.

     Further investigations during the harvest time should be con-
ducted to determine if chlorinated hydrocarbon pesticides are present
in the fruit.

                       REVIEW OF NEIC PROCEDURES
                       PESTICIDE USE OBSERVATIONS
                         Wareham, Massachusetts
     Records regarding the Pesticide Use Observation Study were
evaluated against the established NEIC sample and document control
procedures.   Field data records, log books, sample tags, and
chain-of-custody records were reviewed by the Project Coordinator and
audited by the Enforcement Program Specialist to determine if there
were any deviations from the procedures.  The examination detected no
deviations from procedures.

     Chemical analyses of thirty-two (32) samples collected from the
study sites were completed within the prescribed holding limits.

     The analyses for fish brain acetylcholinesterase (AChE) inhibition
related to organophosphate poisoning were not performed, as outlined
in the Project Plan, because of a malfunction of the analytical equipment.
As an alternative, samples of fish were returned to the NEIC laboratory
and analyzed for pesticide uptake.  The procedural change did not
affect the survey results.

     Deviations from the Project Plan occurred when on-site obser-
vations required the elimination of several sampling stations.
The original station numbering system remained which accounted for
absent station numbers on this report.  This Project Plan altera-
tion did not affect the results of the study.

                             APPENDIX C-I
               METHODOLOGY - THERMOFAX SPRAY DRIFT CARDS
  I. Collection:


     1.   Three types of spray drift cards are attached to a sheet
          of cardboard during sampling.   The types and sizes are:
          Thermofax (10 x 12.5 cm or 4 x 5 in); Kromcote (10 x 12.5
          cm or 4 x 5) and Lingaraph (10 x 25 cm or 4 x 10 in).

     2.   After sampling, the large sheets are placed in a plastic
          bag and transported to the laboratory.
 II.  Extraction:


     1.    Remove the Thermofax card from the large sheet of cardboard.
     2.    Pour 110 ml of hexane into an 8" square Pyrex dish.
     3.    Submerge the Thermofax card in the hexane.   Keep the card
          in contact with the hexane for 5 minutes, turning the
          card frequently.
     4.    Remove the card from the Pyrex dish and discard.
     5.    Filter the hexane extract into a Kuderna-Danish evapor-
          ative concentrator by pouring the extract through a
          funnel  containing Whatman #3 filter paper filled with
          Na2S04.   The filter paper and Na2S04  are prewashed
          with hexane.
     6.    Rinse the dish with hexane several times and add these
          rinses to the Kuderna-Danish evaporative concentrator
          through the Na2S04.
     7.    Concentrate the extract to 10 ml.
III.  Analysis:


     1.    Analyze the extract using a gas chromatograph equipped
          with an electron capture (EC) or an alkali flame ioniza-
          tion (AFID) detector.   The conditions for analysis follow:

                          METHODOLOGY - WATER
  I.  Collection
          Water samples are collected in pre-washed 1  quart glass
          jars equipped with Teflon-lined screw caps.
          The samples are preserved in the field by saturating the
          sample with chloroform and shaking them vigorously.
          Samples are shipped to the laboratory for analysis and,
          upon arrival, stored in a refrigerator.
 II.  Extraction
     1.    Transfer the entire sample to a 2 liter separatory funnel
          and adjust the pH to 7 with 6N NaOM.
     2.    Extract the sample serially with 3 x 60 ml  of 15% methylene
          chloride in hexane.
     3.    Pass the combined extracts through a funnel containing
          glass wool topped with Na2S04 and into a Kuderna-Oanish
          evaporative concentrator.   The glass wool and Na2S04 are
          prewashed with hexane.
     4.    Concentrate the extract to 10 ml.
     5.    Add 50 ml of hexane to the extract and concentrate to
          10 ml on a hot plate under a gentle stream of air.  This
          removes the last traces of chloroform from the extract.
III.  Analysis


     1.    Analyze the extract using a gas chromatograph equipped
          with an electron capture (EC) or an alkali flame ion-
          ization (AFID) detector.  The conditions for analysis

          flask.
     3.    Add 150 ml of 15% methylene chloride in hexane and
          blend for 1  minute with a Polytron sample mixer at  a
          setting of 6-7.   Rinse down the mixing barrel with
          additional hexane and remix for 1 minute.
     4.    Filter the extract through Whatman #1 filter paper.
     5.    Pass the extract through Na2S04 which has been pre-
          washed with hexane and into a  Kuderna-Oanish evaporative
          concentrator.
     6.    Concentrate to 10 ml.
III.  Cleanup - Acetonitrile Partition

     1.    Transfer 10 ml  extract to a 125 ml  separatory funnel and
          adjust volume to 15 ml with hexane.
     2.    Add 30 ml  of hexane saturated acetonitrile and shake it for
          1  minute.   Collect the acetonitrile.   Repeat this extract-
          ion a total of four times.
     3.    Combine the acetonitrile extracts and discard the hexane
          remaining  in the separatory funnel.
     4.    Transfer the acetonitrile to a 1 liter separatory funnel.
          Add 650 ml  water and 40 ml  of saturated NaCl.   Shake the
          sample.
     5.    Extract the H20/acetonitrile solution with 100 ml of hexane,
          and repeat the extraction.   Combine the hexane extracts and
          discard the water/acetonitrile.
     6.    Transfer the combined hexane extracts to 1 liter separatory

                    METHODOLOGY - SOIL AND SEDIMENT
  I.  Collection

     1.    Soil and sediment are collected with a sediment core sampler
          and placed in aluminum foil  and refrigerated until  analyzed.
 II.  Sample Preparation

     1.    Pass the sample through a 2mm sieve.   Sediment samples
          may have to be air dried before sieving to facilitate the
          procedure.
     2.    Weigh approximately 10 gm of sampling into a tared beaker.
          Record the weight.   Place in a 105 °C oven overnight and
          reweigh to determine moisture.
III.  Extraction

     1.    Weigh 25-50 gm of the sieved sample into a 500 ml  Erlemyer
          flask.   Add water, if necessary, to adjust the moisture
          content of the sample to 15% minimum.
     2.    Add 40 ml  of acetone and shake the sample on a wrist action
          shaker for 20 minutes.   Add 80 ml of hexane and shake the
          sample an additional 10 minutes.
     3.    Decant the solvent into a 1 liter separatory funnel.
     4.    Add 20 ml  more of acetone to the sample and shake  it for 20
          minutes.   Add 80 ml  of hexane and shake the sample for 10
          minutes.
     5.    Add this solvent to  the solvent already in the 1  liter
          separatory funnel.
     6.    Add 500 ml of water  to the separatory funnel and  gently
          mix for 1  minute. Collect the hexane layer.
     7.    Back extract the water layer with 25 ml of hexane.   Com-
          bine this hexane with the hexane collected in (6).
     8.    Pass the combined hexane extracts through prewashed Na2S04
          and into a Kuderna-Danish evaporative concentrator.
     9.    Concentrate the extract to 10 ml.
III.  Analysis

     1.    Analyze the extract using a gas chromatograph equipped
          with an electron capture (EC) or an alkali  flame ioniza-
          tion (AFID) detector.   The conditions for analysis follow:

   REGULATION III — General Provisions
   1. It is recognized that certain waters  of the Com-
 monwealth possess  an existing  quality which is belter
 than the standards assigned thereto.
   A.  Except as otherwise provided herein, no new dis-
 charge of wastewater will be permitted into any stream,
 river or tributary upstream of the most upstream dis-
 charge of wastewater from a municipal waste treatment
 facility or municipal sewer discharging wastes requiring
 appropriate treatment as determined  by the Division.
 Any person having an existing wastewater discharge shall
 be required  to cease said discharge  and connect to a
 municipal sewer  unless it  is shown by said person that
 such connection is not available or feasible. Existing dis-
 charges  not  connected  to a municipal sewer  will  be
 provided  with  the highest and best practical  means of
 waste treatment to maintain high water quality. New dis-
 charges  from a municipal waste treatment facility into
 such waters  will be  permitted provided that  such dis-
 charge Is in accordance with a plan developed  under the
 provisions of Section 27( 10) of Chapter 2 1 of the General
 Laws  (Massachusetts Clean Waters Act) which has been
 the  subject of a Public Hearing and approved by the divi-
ision. The discharge of industrial liquid coolant wastes in
' conjunction with the public and private supply of heat or
•electrical power may be allowed provided that a permit
 has been issued by the Division and that such discharge is
 in conformancc with- the terms and conditions of the per-
                                              0-4

mil and in con Form ancc with the water quality standards
of the receiving waters.
  B. Except  as otherwise provided herein no new dis-
charge of wastcwalcr will be permitted in Class SA or SB
Maters.  Any  person having  an existing  discharge  of
wastewater into Class SA or SB waters will be required
to cease said discharge  and  to connect to a  municipal
sewer unless it is shown by said person that such connec-
tion is not available or feasible. Existing discharges not
connected to a municipal sewer will be provided with the
highest  and best practical  means of waste treatment to
maintain high water quality.  New discharges from  a
waste treatment facility into such waters will be per-
mitted provided that such discharge is in accordance with
a plan developed under the provisions of Section 27(10)
of Chapter  21 of I he  General Laws (Massachusetts
Clean Waters Act) whirl) has been the subject of a Public
Hearing and approved by (lie Division.  The discharge of
industrial  liquid coolant wastes in  conjunction with ttic
public and private supply of heat or electlical power may
be allowed provided that a permit lir.s been issued by the
Division and  that  such discharge is in conCormancc with
the terms  and conditions of the pc.nnil and in conform-
