1.0 , INTRODUCTION
Analytical Services, Incorporated. (AS) is pleased to submit this Tier .3 groundwater
.assessinent report for the Sbadwell Market property oil behalf of the property owner., Mr.
Lloyd Wood. The report has been prepared to address the .requirements within Section
206 of the Albemarle County Design Standards Manual.. The subject property is.located
just cast of theintersectionof Roi.ite..25 - 0 and Route 2.2, in Slia.dwoll,'Virginia. The subject
property consists of approximately 1,.17 acres which,is currently improved by an existing
C.Onve*iiience store and .associated fueling islaud. The,planned development will :include
tit&. building of a new!8tru.c.turQ on the eastern ,portion. of the .site twhich will replace the
existing structure: Rtedevelopment plans f6r,the project have been prepared by-M.6Kee
Carson f6r the pro pery owner Mr Lloyd Woo Water supply to -the. existing site is
provided by a -single bedrock supply wells which was constructed on the propert Y .iii
1976: The splanned development;of the new .Sliadwell:Market will continue to utilize this
well.. VWe understand that the :site wi11 utilize approximately 4:0.0 gallons: of groundwater
per day.
2..0 . SITE DESCRIPTION
2.1 Topography.
The -subject property consi-sts of 1. 1�7 ` acres,situated. just east of the intersection of Route
250 and Route 22. The existing convenience store and associated parking area lies
between Route 250 and Route 22. The majority wof,this area i s r .01 ati Y l y
flat with the
e.Nepp embankment hear the eastern portion of the 'site. The site extends
exception, an e n
southward. across Route 250 and this :portion of the site is currently ,undeveloped. The
southern. 1 shoulder,, of Route: 250 slopes steeply:downward to a rel-ativeIrflat.area. -where a
proposed .drainfibld for the site is planned. The propert-y'.extends southward and borders

along the:southernportion of the site,,
2.2 Surface Water Drainage
Surface water :drainage. on the subject property is: ac.c.Qmm.odatcd by storm drains aild by
sloping topography, Drainage fi-oin the-northwestem.. port ion offhe site . currently enters a

.2A Land Use
Analytical Services obtained and reviewed planinietric.mapping -fi-oin Albemarle County
to aid in assessing land use in the larger site area. Adjacent properties (to the subject
property) are either -undeveloped or developed with :cominercial and or- industrial use.
The Stond Rob son Scho 01 i' ; also located approxiinately, 100-0 f oefsoufh- of tl' e southern
s
most property boundary. Usin lin
.g the plan' etric tapping, AST identified approximately
six structures within.-roughly 1000 feet of the site boundary (Figure 3):
The area to thenorth of the:site,is understood to be the Edgers oi.it.Varm which: appears to
have millim6l development At this tinid in the vicinity of the subject property; . However
an, existing gr-du-,nd*ate.r well, Which does not appoaf-to be in use was: identified: just
across Route 22 ftPfn..th6 site., hi additiot, 6 fi I ite hydtalit was observed of thd,borth side
of Route 52.2, MT. Woods, the property owner, -indicated that public-Water Was available
for fire -protection: :only; and not fordomestic consumption. The area east: of the existing
stilaoffire is bordered by a large concrete retai'ming. wall. Beyond the wall lies a parking
area ..aii.d relatively lai'gt.b-,uildiii 9 that is*currently for` sale. The sigiiage for the building
.indicated a former Wine and Gourmet Shop. The Stone Robinson Elementary School is
located south of the. site across the CSX Railroad tracks. Luck Stone: Corporation
operates a quarry near the site and the Luck Stone property borders the southwestern
portion.of the subject site.
3.0 PROPOSED DEVELOPMENYLAYOUT AND LAND DISTvRBANCE
The development plan, prePared by M6Kee:Carsoii.j -provides details on the proposed
.development and disturbanc*e. Figure 2. shows the liettlallocation of site boundaries and

4.0 GROUNDWATER. AVAILABILITY
Tlid plaiuled Shadwell Market :dev.el,opmcht will utilize an existing well for groundwater
sup} ly that has.lii•ovided .service to the existing convenience store since 197.6. Prior to
the. installation. of the well, the site had utilized a spring fed system for water supply. The
spring, :which is located on the south side ofRoute.250.,,became inopei:able,when piping
beneath Route 25`0 apparently.deterlorated. Albeniai:le.County Groundwater Availability
Maps ing indicates .that, "flee entire site .lies WithliiAlie Category 2 (Mgdiuni.) .Groundw:ater

store structure. Select photographs of the -site qded as:.ADljbjjdix B.
Mr. Wood was asked. about. the 'source for water supply,and. sewer for the- existing site.
According to Mr., Wood, the site, has been serviced by a,sitigle, W.611 since 1976. The
location of the well was indicated by - M - r. Woods: and is: located near Route 22, oil the
north: side of the existing structure-. The wellhead was surrounded by tectangular steel
tubing for protection. Prior to. 1976 the, site has utilized a spring system on the southern
portion of the site for water supply which was piped:buneath Route 250, Mr. Wood said
that the. existin a structure does not hava a. baffiro6m. A sink dt the site i§,iised:aiidhewas

as a convenience store and gasoline station, since; the 195 . Os, !'it had previously been
operated :as a post office.
According to. Mr., Wood, ;the site previously had underground storage tanks (U,.ST9) Which
were removed., New USTS were then installed, at the site by Quarles Petrolquili.
According.to Mil; ',ATbod the property does. not have an y en ding pollution cases with the

aide), of the building. Mr. Wood indicated that Quarles Petroleum would have more
information on the tanks at the site:
.AS:I contacted Mr. Billy Quarles, with Quarles Petroleum, to obtain additional
information on the both the use of existing and former USTs. at the site. Mr.. Quarles
:indicated that two. (2) USTs are located on tlre: site. One .UST is 8,000 gallons in. size and
is used to store regular grade gasoline. Anotlier UST, which is .6,000 gallons.in ize, is
used to store super grade gasoline. 'Both tanks are fitted to a third ,dispenser so aliat they
can be'blended and :provide mid - grade gasoline: Tbd tanks.are believed to lie single -wall
steel tanks tliat are. coated with fiberglass. Such tanks are routinely referred to as "Buff. -
Hi;de" 'tanks. Mr., Quarles suggested that.. ...;P.. with Mr:. Erick: `Hiltzlei; .Quarles
Petroleum's Environi iental Director, to :obtain :additional : nforination on the history of
USTs at:the.subject:,property. Mr. Hil.hier indicated :that; dui.ing the itemoval of the former
USTs, petroleum contamination -was enco.unter..ed, During, the removal, the Virginia
Department of Environmental Quality ..(D:EQ) was reported to be involved and petroleum
impacted soil was excavated and removed fiom thesite:forproper di'sp:osal. According to
M1, Hiliner, the site cliaracterization activity involved the completion and sampling of
three .shallow, monitor wells .at the site. While die report of this work was; riot readily
available, Mr: Hiltner indicated that :the DEQ closed tl1..e.case: iii, a very timely 11i
upon con pletion.of the site characterization activity. Tvh;: H:i.ltaer, was asked if the-s to
monitor wells were properly:abandoned:and he indicatetlzat to:lis knowledge they were.
During the site reconnaissance; much :of the site was observed to be gravel surfaced;.
including :a parking lot in the rear, or eastern-:.side, of the building; Limited . asphalt
paveirieiit tivas observed: A fi•eezer tint was. identified 'adjacent to the east side of ;the.
buildi g: A relatively steep %embankment was observed along.the. extrem;e,eastern.po •tion
of the site adjacent to the northeizi. side:of :Route 250. A drainage dutch. was noted ;at the.
base of this. enb:aiikmei %t which appears to drain to the :east. S:cattered...domestic : debi7s
were i'denti'fied in this area. A storin, drain was ideritifled. within Ilie harking: area in front
of the building. !t was not clear where the drain discharged;
Afire hydrant was observed along the noithern side .of Route 22, .across from the subject
site, :oil property—identified by Mr. Wood ..as'the Edgemont Fami: Mr. Wood indicated:
that the water line supplying the hydrant was provided by ClZarlottesville for fire
protection and was not accessible for connection for.public water.supply When asked
about planned water consumption :for the new building, Mr. Woods indicated that it
would be minimal... He stated that the, site would have restro.oms and a septic field for the
new building would be located on the southern side,of :the property, across Route 250.
When.asked about the quality of the-water. froin the well :and the well yield; Mr. Woods

well data reviewed, thzxis�ting site well 11 appears to, nearly match the -average yield for
the area. The use of this well by the: site owner siiice-1976.; without any reported
problems , 'regarding, .quality or quantity, suggests that the well would be expected: to
continue to provide adequate groundwater :resources:for the site. Given the size� of the
site . and the location of the planned` buildings and septic field, there ;may be limited
options for any additional well. sites on this PI-Operty. Every attempt should, be made to
protect the integrity of the. well. head and su !ounding,sourco water area.

8A. CONCLUSIONS
1. The project site is located in a D-oundwater availability zone where successfully
placed wells possess an average yield of nearly 14 gallons per minute, (Pha:se 11
Albemarle County Hydrogeologic Assessment Report). The construction well log
for ,the .existing site well, ilidi.cates a well yield of 15 gallons per iiiinute. This
well,, wl lich has been in service as'� not experienced any
osljndd 1976 problems,

Protective measures :should be .implemented prior: to begilmiiig `construction
activity on the site.
4. -County wide sensitivity :mapping indicates that the subject site lies within an
identified sensitive area. The sensitive area is associated with USTs, both on the
site and in the nearby.area: A D.EQ po:liuti.on..case was confinned .for .the site. in
1.994 and is currently listed .as' being closed by the DEQ. According to
information obtained I= Quarles Petroleum, :a release of petroleum has
previously occurred at. the site. Following the removal of petroleum .impacted
soil and the.::completion. of a site :characterization study the. case was closed by y the
DEQ. Due to the historical use of USTs at the -site, includin a foriner petrol etiiil
release and the continued use of the site for petroleu>n storage, periodic
monitoring of the groundwater well.,for quality is recommended.
.5 AS projected groundwater use at he .S.h.Adwell Market: is deeined to be minimal
(approximately 400 gallons per day),'the planned ;use of the site appears to ni, atcl
well with the opportunities of the groundwater resource. While much of the site
area between Route. 2.5.0 and .Route 22 will be paved.. or'built upon, the southern.
portion of the site mslould provide. o:pp.oriuility -for 'continued groundwater
:recharge.
