Albemarle County Jurisdictional Area request for water January 6, 1999
service-GOCO Oil Co.
ACTION: X INFORMATION:
SUBJECT/PROPOSAUREQUEST: CONSENT AGENDA:
Consider holding a public hearing to amend the ACSA ACTION: INFORMATION:
Jurisdictional Area to provide water service to GOCO Oil Gas
station on Route 250 East in Shadwell (TMP 79-18).
ATTACHMENTS: Yes
STAFF CONTACT(S): l
Messrs. Tucker, Climberg, Benish, REVIEWED BY:
BACKGROUND:
The applicant, GOCO Oil Company, requests Jurisdictional Area designation for water service to the GOCO Oil gas station at
Shadwell. The 1.02 acre parcel is located on the north side of Route 250 adjacent to the Norfolk Southern railroad and is designated
as Rural Area in the Land Use Plan (Attachment A). The request for water service is due to the contamination of the well serving
this site with the gasoline additive Methyl Tertiary Butyl Ether (MTBE) (Attachment B). The Board reviewed a request for water
service on this site on March 3, 1993. Although there was evidence of water quality problems at that time, the Board denied the
request for water service because an alternative site for a new well was available (prior staff report, Attachment C).
DISCUSSION:
The attached letter from the Virginia Department of Environmental Quality confirms the existence of petroleum within the existing
water supply. According to the DEQ letter, this is the second well at this facility to"become impacted by the documented petroleum
release."A new petroleum release has not occurred on site, therefore, it is presumed that the contamination of the second well is
a result of a prior petroleum release that affected the first well.
The Land Use Plan provides the following concerning sewer service to the Rural Area:
General Principle: Utilization of central water and/or sewer systems or extension of the public water or sewer into the Rural Area is
strongly discouraged except in cases where public health or safety are at issue.
•
Recommendation: Only allow changes in jurisdictional areas outside of designated Development Areas in cases where the property
is: (1) adjacent to existing lines;and, (2)public health or safety is endangered.
Verification of endangerment to public health and safety is provided in the attachments. An existing water line serving the Rivanna
Village is located along Route 250 adjacent to this property.This line was intended to serve the Rivanna Village and Stone Robinson
Elementary School only. The Land Use Plan further recommends that the capacity of the line should be"reserved...for a potential
for a potential new school in the Village until such time it is determined that the school is not necessary (p. 99)."
RECOMMENDATION:
Based on information provided by DEQ, the request is consistent with the Land Use Plan strategies for the provision of service
outside the designated Development Area. Staff recommends proceeding to public hearing to consider providing water only to existing
structures.

Re: Request for Corrective Action Plan, GOCO Bulk Plant, Shadwell
DEQ Tracking Number: PC 89-1392
Dear Mr. Montague:
The Department of Environmental Quality (DEQ)was notified on July 21, 1998,that the
potable well serving the above facility was contaminated with petroleum. In response to the
report, DEQ sampled the well on July 23, 1998. The laboratory results confirmed the presence
of MTBE in the water, and you were notified of the results on August 4, 1998. DEQ decided to
postpone further action at the site until the completion of a previously initiated AST closure.
Based on a review of the AST closure documents received at this office on October 16,
1998, it appears that a new petroleum release has not occurred at the facility. Accordingly,the
contamination in the potable well is presumed to have occurred as a result of a petroleum release
previously investigated under PC 89-1392. Given this determination, DEQ has decided to
reopen PC 89-1392.
Since the potable well is the second well at the facility to become impacted by the
documented petroleum release, DEQ believes that the best option for a safe potable water supply
is to connect to the Albemarle County Service Authority(ACSA) water supply running along
Route 250. Please submit a Corrective Action Plan (CAP) by December 7, 1998, outlining a
schedule to connect to the ACSA water supply. If ACSA will not agree to your request for
connection, DEQ will attempt to negotiate with ACSA on your behalf.
Since the petroleum release occurred from an AST system and additional impact to the
surrounding community is not-anticipated, public notice of the CAP will not be required. Upon
receipt and approval of the CAP, DEQ will grant a CAP Permit with instructions for initiating

RE: Albemarle County Service Authority (ACSA)
Jurisdictional Area Amendment for David W. Booth/Sandra
Andrews and Sherwood Exum (GOCO, Inc. ) - Tax Map 79,
Parcels 18 and 19
This item will be before you as a public hearing on March 3 ,
1993 . Enclosed is the original report on this matter from
October and subsequent information regarding each parcel.
Tax Map 79 , Parcel 19 (Booth/Andrews)
Samples from the well on this property were taken by Applied
Technology and Engineering, P.C. (January 28 , 1993 letter from
John W. Walenten) . The Department of Engineering has provided
response (February 24, 1993 memo from Jack Kelsey) . Engineering
' Staff does not find that jurisdictional area amendment is
adequately justified.
Tax Map 79, Parcel 18 (GOCO)
This property was the subject of the August 14, 1989 State Water
Control Board letter and the "Site, Risk and Remediation
Assessment of Groundwater Contamination at the Shadwell "76"
Station Shadwell, Virginia" report. Siibstantia-l—petr_o.Ie_uti3
=contamination was found.in-~thez4domesticr`welT:Isupp.ly at ,tfis-stye.
A Corrective Action Plan (page 24 of the report) was identified.
It has since been found that the line carrying runoff from the
gravel area near the unloading rack is not a source contaminating

Page 2
the well. According to Mr. Harry Montague, a representative of
GOCO, it is now believed that contamination of the unloading rack
area and contamination ofthe well were unrelated. The well is
believed to be the source of isolated contamination resulting
from vandalism. The well is no longe.p: being used as there is
only one employee on-site. GOCO has not attempted to establish
another domestic well on-site, although monitoring wells
established for the assessment indicate the contamination was
localized.
Summary
As stated previously, utility service outside of designated
growth areas has typically been limited to those cases where
properties have experienced quality/quantity problems and are
adjacent to existing lines. Booth/Andrews desires water only
and. has a documented coliform level not acceptable for drinking
water. However, the recommended procedure for resolution of this
problem has not been undertaken. Staff does not recommend
jurisdictional area amendment for Parcel 19 (Booth/Andrews) until
the four step procedure for resolving the coliform problem has
been exhausted. GOCO desires water only to existing structures
and has documented localized petroleum contamination. No new
well source has been attempted to be established. The use of the
site is restricted by its non-conforming zoning status and
on-site activities do not require more than domestic water needs.
Staff does not recommend jurisdictional area amendment for Parcel
18 (GOCO) until evidence is provided that no other_ on-site water
source is available.

RE: Site Selection for New Water Supply Well, Shadwell Store, Route 250.
Dear Mr. Montigue:
Per. your request, I have analyzed the groundwater data for the above referenced Site to
determine the best location for the placement of a new water supply well on GOCO's property.
The data.I reviewed is contained in the June 12, 1990 report HYDROSYSTEMS prepared for
submission to the Virginia State Water Control Board and is titled "Site, Risk, and Remediation
Assessment of Groundwater Contamination at the Shadwell 76 Station, Shadwell, Virginia". As
you are aware, the current water supply well is contaminated with petroleum, mainly in the form
of gasoline type compounds. Benzene concentrations greatly exceed the U.S. EPA and Virginia
Drinking Water Standard of 5 ppb. Benzene is a known carcinogen.
To evaluate potential new water supply well locations on GOCO's property, I reviewed all of
the existing data including water quality, groundwater flow direction, potential sources of
contamination, geologic conditions, and available area. Because of the existing severe
contamination in the upgradient areas of the site, the use of a septic field to the north of the
Station, the existence of an underground storage tank, unpaved dispensing areas, and
groundwater flow to the northwest, HYDROSYSTEMS has determined that most of the property
is absolutely unsuitable for the installation of a water supply well. Wells placed within this
area will either immediately encounter contaminated groundwater or will upon usage draw in
contaminated groundwater from other areas of the site once the well is placed in operation.
ThiC eases one small area at-the-southernpoi i ethe-site:3 Placing-'a water supply W6117herg
swill=be 'gamble=at best. Well MW-4 was contaminated with total petroleum hydrocarbons just
above the Virginia Drinking Water Standards. The source of this contamination is not known.
In addition, the most highly contaminated monitoring well on site is only 135 feet away at the
loading rack. cit—is`v"ery61e that=a wateLsupply_wellirr-tti s-location�wilLdraw

contaminated groundwater-from-the—site-to-the north: In my experience, this is not an
uncommon occurrence. I am currently working on a case in Albemarle County where a new
well drilled 250 feet up hill from ai'area of gasoline contamination became contaminated after
it was put into use. Everyone assumed the well was far enough away and was upgradient of the
contamination. Because of the fractured nature or the bedrock aquifer systems in Albemarle
County, the influence of a pumping well can reach long distances along those fractures, even
pulling in groundwater from downgradient areas as was seen in this case.
Because of the severity of the groundwater contamination at this site and the existing geologic
conditions, HYDROSYSTEMS cannot recommend the placement of a water supply well on the
GOCO property. We are not comfortable with the minimal isolation distances available. We
would instead recommend that a location on one of the surrounding properties be considered or
if possible tapping into the proposed water main.
If you have any questions concerning this letter report or if you wish to pursue potential off-site
well locations, please contact me at your convenience.

February 24, 1993
RE:
Jurisdictional Area Request - Tax Map 79 Parcel 19
As requested this Department has reviewed the analysis of the drinking water sampled from
the above referenced private well and the technical grounds for support of an extension to the
ACSA jurisdictional area.
Sampling and testing of this well indicated unacceptable coliform bacteria levels. According
to the Thomas Jefferson Health Department this type of contamination is very common
(especially in older wells) and is a problem they deal with on a daily basis. Very rarely is
the groundwater the source of this type of contamination. Bacteria contamination is
generally due to intrusion of surface runoff into the well as a result of poor installation or (in
the case of old wells) the standards utilized at that time.
The Health Department utilizes a four step procedure for recommending a resolution to these
problems. The first recommendation is to protect the wellhead from the intrusion of surface
runoff, chlorinate and flush the well to remove the bacteria from the stored water as well as
the liner and appurtences, and then test the water. Should these measures fail to correct the
contamination, the second recommendation is to install a new well in accordance with present
standards. If bacteria contamination continues to persist, installation of a chlorination system •
is then recommended. Lastly, for the rare case when all options fail, the Health Department
will recommend the owner apply for extension of the ACSA jurisdictional'area.
As a policy the County has discouraged extension of ACSA jurisdictional areas in other than
County designated growth areas, unless public health and safety is endangered. This site is
not located within a County designated growth area.
Wayne Cilimberg
February 24, 1993
Page 2
The scope of the sampling and testing of this well was limited to the determination of the
water quality in the present condition of the well and are not conclusive evidence that the
well is a danger to public health and safety.
Extension of the ACSA jurisdictional area is not adequately justified until disinfection,
remedial measures to eliminate the source of the contamination, and/or the other options
described above are attempted and failed. Therefore, at this time the Engineering
Department cannot support this request.

Re: Shadwell GOCO "76" - Albemarle County, PC 89-1392
Dear Mr. Exum:
This is in regard to the report of the taste and odor of petroleum in
the domestic well water supply at the referenced site. On April 28 ,
1989 Mr. John Paul Jones, Albemarle Fire Inspector, reported
petroleum contamination at the referenced site. On June 29 , 1989
Mr. Larry Carpenter of this office obtained water samples for,
analysis from the well which serves this site. Analytical results
from these samples (copy attached) indicate substantial petroleum
contamination is affecting ground water at this site.
Due to the presence of this contamination, Valley Regional staff
believe that a site, risk and remediation assessment is necessary to
protect human safety and the environment. Therefore, I must request
GOCO Oil Company to submit a site, risk and remediation assessment by
September 29, 1989 . To be considered complete, these assessments
must address the following elements.

Re: GOCO Bulk Facility, Routes 250'& 729, Shadwell -
- -' -DEQ Tracking Number: PC 89-1392
Dear Mr. Benish:
Per our telephone conversation on January 7, 1999, I have prepared a summary of Department
of Environmental Quality (DEQ)records pertaining to the petroleum contamination at the above site:
On April 28, 1989, Mr. J. P. Jones of the Albemarle County Fire Department reported that No.
2 fuel oil was leaking from a loading rack valve at the GOCO facility. The valve problem was
corrected, but soon after,the State Water Control Board(SWCB),now DEQ,received a report that the
potable well water serving the facility had the taste•and odor of petroleum. The SWCB sampled the
well and determined that the groundwater at the facility was contaminated with components of
gasoline. Accordingly,the SWCB requested that GOCO submit a site,risk, and remediation
assessment to address the contamination.
On June 22, 1990,the SWCB received GOCO's report,prepared by Jeffrey A. Sitler of
Hydrosystems, Inc. Five groundwater monitoring wells were installed at the site to determine
groundwater characteristics and contaminant levels. Groundwater flow was measured to be to the
west-northwest toward the western corner of the site near the intersection of the C&O railroad and
Route 250 (see Figure 5). Given the extreme geologic heterogeneity, groundwater velocities at the site
were estimated to range between 20-550 ft/yr. Significant dissolved-phase contamination was
encountered only in the wells in the vicinity of the loading rack(MW-1, MW-2, and the potable well).
These wells had significant concentrations of BTEX compounds--benzene,toluene, ethylbenzene, and
xylenes--indicative of gasoline. The downgradient monitoring wells (MW-4 and MW-5) and the
Mr. David Benish
January 24, 1999
Page 2
intermittent stream located along the northern boundary of the property did not have detectable BTEX
levels. No free-phase petroleum was encountered in any of the monitoring wells.
According to the report,the GOCO site has been utilized as a commercial gas station and bulk
distribution center since approximately 1940, and the observed groundwater contamination was
attributed to repeated leaks, spills, and overfills at the loading rack. The lack of contamination in the
stream and downgradient monitoring wells indicated that the contaminant plume was stable and was
not migrating from the site. GOCO declined assistance from the DEQ's alternate water supply
program to address the contaminated potable well, and since no additional investigation was warranted,
DEQ.closed the case on August 2, 1994.
On July 21, 1998, Mr. and Mrs. Jacques Logarides visited DEQ and reported that the potable
wells serving the GOCO facility and the Shadwell 7-Day Junior convenience store at the intersection of
Routes 22 and 250 were contaminated with petroleum. Mr. and Mrs. Logarides were concerned
because they were planning to purchase the parcel of property between the two sites, and they did not
want to have a contaminated drinking water supply. In response to the report, I visited both sites July
23, 1998,to collect water samples. At GOCO facility, I discovered that a new potable well had been
drilled in the early 1990's. The sample results indicated that the well serving the 7-Day Junior store
was free of contamination,but the new well serving the GOCO facility contained MTBE, a gasoline
additive.
Tests for MTBE had not been run at the GOCO facility prior the July sampling event, and in all
likelihood, MTBE has been present at the site since the original pollution report was received in 1989.
Because MTBE may serve as an indicator of more toxic and/or carcinogenic gasoline constituents,
DEQ required GOCO to inquire about connecting to the Albemarle County Service Authority water
line running along Route 250. DEQ considers this to be the most cost-effective solution to address the
contaminated water supply issue at the GOCO facility. If you have additional questions about the
content of this letter,please contact me at 540-574-7846.
Sincerely,
