Dear Mr. Salvetti,
BENNETT & O'REILLY, INC., bas prepared the following Report and Supporting
Documentation as a surnmary of findings relative to the lmmediate Response Action (IRA;
corryleted a tbe above referenced hcatbn in the period ofAprfl 8, 1998 tbrough June 11, 1998. The
IRA was completed to mitigate environmental and health hazards identifed with the release of an
unknown quantity of fuel oil from a leal<mg 275 gallon underground storage tank as discovered by
A&znced Environmemal Servic€s in Apnl 1997. Tbe IRA conducted by BENNETT & O'REILLY,
INC., included: 1) the remoral of fJ.f,{ 16ns 6fgonhminded soils in the area of the former UST and
extending to the cellar area under the dwelling, 2) the evacuation of 660 gallons of irnpacted
groundwater from the groundwater interhce within the excavation, and 3) the construction atrd
capping of a passive Soil Vapor Exraction System (SVE) to serve as a subslab venting system
within the area of excavation These remedial actions were accoryanied by an environmental
assessrned progam to evahute the effectiveness ofcleanup activities and evaluate risk to identified
environmental and human receptors. The contaminated soils generated were tralsported to the
Bardon Trimount Facility in South Dennis, MA for licensed recycling under an approved Bill of
Lading. The contaminated groundwater was mnsported for recycling to the licensed Olson's
Greenhouses in Raynham, MA under a Hazardous Waste Manifest. This report is an addendum to,
and essential part oi the modified lmmediate Response Action Plan verbally approved by the MA
DEp (SERO); BWSC/ERS [Dan Crafton] as set forth in correspondence filed with the Department
dated April 8, 1998.

SITE F'EATURES [Ref* toAppendixA]
The W'ollerman property, shown as Lot A22 on the Yarmouth Assessors Map 20, is located
immediately south of Route 28 between Hudson Road ond Appleby Road in West Yormouth some
1,000'west of the Pokers River [refer to Figwe 1]. The property contaira some 0.83 aoes of land
oea od is developed by fow ingle storey wood frome dupl* cottages strrounding a cental pool
area. Two of the cottages (12-14 ond 18-20) are located on Hudson Road and the rernaining two
cottages ( 7-9 and 11-1j) are located on Appleby Road. The two cottages along Hudson Road are
ctrren y rented os residcntial dtcllings [refer to Figre 4]. The two cottages on Appleby road are
currently vacant. The sabject Yollerman property was originally a portion of the Seagull Beach
Motel properly to the north operated as the 'Vacationland Resort" through the mid-1960's. The
Wryrties vEre seryded tn 1967 ,i,hen Valtet Wollem@, prchased the subject site and contimted
to operate the cottage colony as the "Arcadia Cottages". The seasonal rental use of the property
as o cottage colony was discontinued in the early 1990's.
The abutting properties to the north along Route 28 are in high density commercial use as
a restautant @lack Rock Grill) otd motel (Seagull Beach Motel), as consistent with the Route 28
corridor between llyannis od Dennis. The properties to the soUh are primarily in high density
residential use with single family dwellingt on 0.2 to 0.3 acre parcels. The area is generally low
lyingwith sMtow groudder (<15' 4L) associaed with the tidal esuay represented by Parkers
River [refer to Figure j].
Detailed consideration of the MA DEP/BYSC GIS mqs shows lhe area along Route 28 is
within the nopwd Non-Potential Drinhng water source area (NPDYSA). This mapping is
consistent wii the W and LIC classifications for trbanized oeas along a mdiol transportation
corridor where there is a high density of commercial development as descibed abow [refer to
Figqe 21. The stbject ite falls within the B-1 Business Zone shown on the Yormouth Zoning map
i*rifng 500, in enhei stde of Route 28 [refer to Figwe 5]. Because the wbiect property has

On Febntary 23, 1998, BENNETT & O'REILLY, NC., proceededwith an initial series of
six (6) hand borings to delineate the extent and magniude of residual soil contdmination.
Additional hotd boings were con&tcted on i/l l/98 and 4/2/98 to firther qualify the dovmgradient
limit of significant capillary fringe impact. Two foot soil samples were collected at each location
from the rurface to the groundwater interface for field photoionization (PID) screening by "jor

On 3/20/98, an additional groundwater sample was collected at the downgradient MW-S
monltor vell for standod &inking *wer unlysis in review of the applicable groundwater category.
Laboratory results slow that grondwoter at the MW-5 location has an eleyated sodium content and
metal concentrations (irory'manganese) on an order of 5 to 10 times the drtnhng water standard as
cottsistent with the USGS (traer-Resowces Investigation Report 94-4156) map entitled "Potenttal
Water Supply Areas of Cape Cod", where the subject ite is mapryd within the arca of greatest
limitation due to saltwer intnsion ond impired *aer quality associated with business/utility land
use [refer to Figure jJ. This plrysical testing and the referenced doctrmentation fiirther qulified
the rubject property as wirtin the NPDWSA, in accardutce with the ptovisions of j 10 CMR 40.0932
(s)@(2).
On April 8, 1998, BENNETT & O'REILLY, INC., contacted the MA DEP (SERO),
BWC/ERS to review analytical test results recieved in the period of 3/l l/98 to i/30/98. Because
of time constraints to implement and complete remedlal lesponse actions without further delay,
verbal authorization of an Immediate Response Action was requested. The proposed IRA tould
require the slwring of the single story, wood framed cottage. The cottage will be held in place and
clean overbwdcn segegdted arrd stocbiled on site a assisted byfield PID screening using a 5 ppm
field guidance level as indicated by initial anolysis. Excavation of antaminaed soils below 3' in
a 25' x 20' area tould be con&tcted in the wea of the former UST and extended under the dwe ing
for the removal of soils to the capillary fringe. Excsvation of contaminoted soils through the
capilloy fringe would be accomplished through de-watering. Impacted groundwater twuld be
allovcd to acc.ntulate into the open excavation which will be sdmmed to remwe any LNA?L and
cont@ninated gouMer. Verbal qprwal of the proposed IRA was granted by Dan Crafton with
doantentotion provided to the Depotment in conespondence from BENNETT & O'REILLY NC.,
datedApril 8, 1998.
REMEDUL RESPONSE [Refer to Appendb B]
Implementaion of the IRA uns delayed because of permitting issaes raised by the Yarmouth
Building Departnent as complicated by the Butlding Inspector's leave. W'ith permitting ond site
preptation completed by Ewirofufe, additional response actions proceeded under the supervision
of BENNETT & O'REILLY, NC., on 5/13/98. A portion of the western foundatton wall was
iemoved and an occess ramp was constructed beneath the building to facilitate soil removal
operdions. Clean overbtrdei was stoclEiled on site, as facilitated by Jield screening. An area of
soil contamtufiion appro*mtely 26'. (L) x 22', (W) x 9',@) was defined extending under the dwelling
to the east, originatingfrom the from the former UST locdion.
contaminated soil removal and stoc@iling proceeded through 5/15/98. Composite soil
sanples collected were feld screened using an HW PI-101 Photoionimtian Detector with a l0'2
eVionp,inaccordorcewiththeMADEi"Intertm...SoilsPolicy"YSC94'400. Afieldvalueof
5 po'ti per million (ppm) was used to define the extent of excavation

IRAC/RAO RTN# +13054
W'ork proceeded with the removal of contaminated soils to the groundwater intedace,
approximately 8' belot, grade. Random field phuoionization readings along the northern and
westera sidewalls were corcistently below l0 ppm as indicating sufficient soil removal in these
oeas. Lilcewise, photoionlmtion screening of the narthern half ond westem holf of the respective
eastert and sotlhern sidewalls, recorded detector response consistently below l0 ppm. Elevated
photoionization detector response in the southeast corner of the excaeation indtcated that the
laeral extew of contarrirution in this qea qten&d beyond that which was originolly estimated and
the capcity of the available shoing. To quolify the need to flrthel extend the lateral ertent of soil
removal in this oea soil samples *ere collected for confirmaory hborotory analysis. Subsequently,
a slonp *as constructed in the ,rortheast corner of the ercavation and a vac-tntck wss utilized to
de*aer the bottom of hole tea to advance the vertical qtent of excavation to 9'. A conJirmatory
soil sample was collected from the bottom of the hole for laboratory analysis- The vac-truck was
shut down and grotmdwater was allowed to accumulale in the open exccvation. This impacted
groundwater was periodically skimmed oyer a 4 hour period. A total of 660 gallons of impacted
gtototMer vtos removed and trasprted to Olson's Greenhouses in Raynham, MA for recycling.
Absortent pds v,vre plocel in the open *,cavation as a precautionary measwe ond to evaluate the
accumulation of any free product. The area was secured with fencing and the stocfoiles covered
pending receipt of laboratory onalysis. Soil samples for the bottom of hole @OII, sidewalls (SW)
and clean overbrrden were submitted to Groundwater Analytical of Buzmds Bry, MA., for Rush
analysis of TPH GdFID.
Prior to leaving the site, BENNETT & O'REILLY, INC., sampled monitor wells MW-i and
MW-4. The sanplingvqs used to confrrm groundvater conditions immediately outside the area of
excavation (withtn l0) through the projected Time of Travel, as previously te*ed. Groundwater
samples were analyzed for IutA DEP EPH analysis with tmgeted analytes as consistent with the
"Inpletrctation of the MA DEP EPII/WH Approach" poliq (10/j1/97)for *eathered fuel oil as
de termine d by prellminry assessment.
Laboratory rerults for TPH CtgFID analysis of sidewall and bottom of hole samples,
received on 5/20/98, indicated residual soil contamination within the sidewall east, side'tall souh
potentially botton of lwle areas exceeded tlu Method I - Risk Choracterization standods for the
appropriate soil categories. TPH concentations reported within the sidewall nonh and sidewall
west samples were repofied as Below the Reporting Linit @RL < 69 ng/kg). The TPH
concentlation o! the clean overbwden was reported at 69 mAkg. Laboratory analysis of
gromdWer sa tples ot Mtr-3 otd MV4 reponed all fractional EPH and target anolytes as BRL.
subseqnnt to corrsultation with the homeowner, BENNETT & O'REILLY, NC., scheduled
additional siil remwal with boiroSafe, as facititated by_additionol shoing and inslructed the
labofdory to re-run the bottom of lole somple for MA DEP EPH analytis with targeted analytes,
as consistent with the " Implementation of tlrc MA DEP EPII/WH Approach" policy (10/31/97).

On 5/21/98, BENNETT A O'REILLY, INC., returned to the site ond conducted a series of
laterol hand borings into the southern and eastern sidewalls to establish the lateral ertefi of
capillary finge soil contaminotion in consideration of additional shoring requirements. Field
photoionimtion indicated thal a 3' exlension of soil removal in these areas'nnuld be adequate to
neet Methd I - Risk Claracterization standards. Supplemental shoring was installed to facilitate
this additional soil removal. No ignificant impact was noted within the exposed groundwater with
minor areas of sheen in the orea of contdct with the south and east sidewall.
Iabordory oulysb, recetved 5/22J98 ord 5/29/98, reponed the si&wall east, sidewall south
and bottom of hole oeos as below the apploptiate S-1/GW-2, Method I - Risk Characterization
standards. Subsequent to consultation with the homemner regoding the feasibility to meet
background condttions, the excsvation contractor wos bstructed to bacl$ll the area of *cavation
installing a soil vapor recovery system (SW) 1' obove groundwter on a bed of I %" stone and
cqped with poty slieeting. The exhotut port wcis vented above the roof ltne with a turbine vent to
facilitate sub-slab venting of any organic vapors and natural attenuotion and biodegradation of
residual contaminotion impact.
A total of 65.84 tons of contaminated soil was transported on June I I, 1998 to Bardon
Trimount in South Dennis, MA. The completed Bill of Lading is included with the Supporting
Documents in Appetdb C. The contractor has subsequently reconstnuted the cellar area and
removed the shoring from under the dwelling. The clean overbulden stocblled on site has been
utilized as fill ogaiwt the rc-constructed cellar with additional clean sand-

Preliminary assessment activities conducted by BENNETT & O'REIAY NC., in the
development of the.Immediate Response Action had included monitor vell gauging to qualify an
easterly grototd*we:rflow direction Q,l89E to S56E) and to confirm thot the AE-3 (MW-j) and the
AE4 (IuM4) monitor wells me lepresentative of potential grondwater impact and contaminant
migration o&side the hrmediate oea of release. Groundwater samples collected by BENNETT &
O'REILLY, INC., on Februory 23, 1998, reportedfractional MA DEP EPH as below the method
reporting limit as irdi@lng no significox grouMer impact o*side the immediate release oea.
To fir'ther EnliIy these fndings, the projected Time ofTravel for dissolved phase petroleum
contaminant migrotion was estimoted from the UST grave to the AE-i(tlW-3) and AE-4(lulW-4)
monitor vrells to govide confrnnatory woteT malysis. Using tle site specific lrydroulic gradient and
consemtive lry*aulic cotductivity/porosity values, Time of Travel between the area of release otd
the domgrdient monitor vells was computed to be 12 days. Therefore, sompling of monitor wells
MW-3 ord MW-4, qproximaely 7' and 10' downgradient, was funher quolilied as representative
of downgradient impact intermediate to the sensitive receptors, well within the projected time of
impaa for the release offiul oil which hod ocarred prior to April, 1997 (300+ days). The samples
colleaed on May I 5 , I 998 rwre sent to Groundwater Analytical of Buzards Bay, MA for MA DEP
EPH analysis, with toget oulyes, as cottsistent with uuahered fuel oil doatmented by preliminary
a.sses$nent. Labolatory results received on 5/20/98, reported EPH values, and torget analytes,
below reponbY limit (BRL). Tlu reporting limtts for the fraclfional EPH compounds, and the target
otaytei (yqWnoUne, 2-Mettrylnaphthalene, Phenanthrene and Acenapththene) are less thon' or
equal to, the Method l-Risk Cheacterization thresholds for the GV-l, GY-2 and GY-3
