contamination, property lines, and rights- of- way'or easements;
• Graded to divert surface run -off from the well and to prevent-pondiing on the well :lot;.
• Served by an all- weather access° road;
• Any well lot located in an area that livestock has been or will be used, must have a fence placed
around the well lot.
The requirements for constructlon and development of new wells are covered in the Commonwealth of Virginia

Dear Ms. Ambler,
This letter is in reference to my June 26, 2006 evaluation of two proposed well sites for approval as a public water
supply source to eventually serve the Red J3i11 Sellool and 12 nearby residential connections in Albemarle County;.,
h accordance with Section 12 VAC 5.-590- 280 of the Commonwealth of Virginia Waterworlrs Rogulatlons, this latter is
to advise that the proposed well sites approximately located on the attached wap of the Oakey property are, tentatively
approved by this Office for construction, The wells shall meet Class H-13 specifications as set forth in Section 12.. VAC
5. 590.846 A4b oftho Commonwealth of Virginia Water°worla Regulations.
This approval is valid for a period of 12 months. If construction of the. wells has not commenced by June 25, 2007.a re-
evaluation of the well sites will be required. The following itemsldocuments must be submitted to this office .for final
approval ;.
1. The wells must be located at least 50 feet inside the boundaries of a surveyed, platted, and .dedicated well lot.
The well lots must be graded to divert surface runoff from the well and to prevent ponding on the well lot,
and an all - weather access road, public or private, must be provided to each well lot. The well lot plat:must
be recorded in Albemarle County with the well lot dedication document. An example well lot dedication
document is enclosed for your information.
2. The wells must be constructed to meet Class II -13 requirements. The wells must be cased with approved
casing to a depth of not less than 50 feet amid the bottozn:of the well casing must temiivate in solid bedrock or
other impervious formation.. In addition the wells must be grouted with neat cement grout to a depth of not
less. than 50 feet. A signed copy of the well drillcr's water well cornpletion.report must be provided to this
office h1dicatitig these minimwn construction requirements have been met.
During construction of the wells, it is requested that the Lexington Envilonnaentai Engineer' :Field Offzee
be notified of the date and approximate time that grouting of the wells will be accomplished. Please transmit
this notification as soon as the information is available to you so that an engineer from this Office can be
present, if possible,
4. Upon completion of the wells, a yield and drawdown test of a minimum duration of 48 hours is required to
determine the reliable well production, A copy of the completed test results must be submitted.

5, Near the end of the yield. test, water samplos' must be collected for metals, inorganic,. organic, radiological,
and nitrate analyses, You may use the state laboratory or any certified private laboratory for these analyses.
You .should be aware that few, if any, single private :laboratories will be certified to .conduct all of, the
required analyses so you may have to use several differont.tabs to cover all of the required tests. We have
enclosed a summary of all of the required chemical analyses and the associated state-laboratory fees for your
information. You are requested to notify this office for assistance in the proper collection of these samples
and to insure that all required..parameters are included in the analyses.
6. A series of twenty bacteriological samples must be collected from the discharge of each well and submitted
to. the state laboratory or any certified .private laboratory to determine the bacteriological quality, of the raw
groundwater prior to the issuance of an operation permit One bacteriological sample must be collected each
hour, of the pumping test. These samples must be analyzed by the total colifonn Most Probable Number
(kVJlPN) test method, Additional - bacteriological :monitoring or other quality .evaluations may be required
depending upon the specific geology of the site and other factors, The :need for additional water quality
evahiations will be determined on a case by case basis.
A
7. Upon completion of the wells and submittal of the samples; plans and specifications for construction of the
well house and development of the well lead must be submitted to this Office, for review i n accordance with
Section. 12 VAC 5-590-280 of the Regulations, These plans and specifications must be prepared by a
professional engineer licensed in Virginia.
Upon receipt of all required information and documents, and after approval of the plan's and specifications have been

Chlorination, soda ash and orthophosphate injection
Three wells
4,000 gpd
The Red Hill School public water supply consists of three drilled wells, a 6,000- gallon hydropneumatic tank,
chlorination plus soda ash and phosphate treatment.
Well No. 2 is located in a softball field (right field) at the base of the hill behind the school approximately 300
feet east of the school building. It is drilled to a depth of 345 feet and buried under a poured concrete pad.
Estimated yield from this well Is 7 gpm based on pump capacity. The depth of casing, grouting and reliable
well yield is unknown.
Well. No. 3 is located approximately 200 feet east of the school at the top of the hill adjacent to the filter
building. It Is drilled to a depth of 365 feet and supplied with a well cap and sealed conduit. The casing is 6
inches in diameter and terminates 1.2 inches above a 6 -foot by 6 -foot concrete pad. Estimated yield from this
well is 4 gpm based on pump capacity, The depth of casing, grouting and reliable well yield is unknown,
Well No. 4 is located approximately 300 feet south of the school building along the southern property
boundary. The well was completed on August 22, 1997 and is drilled to a total depth of 405 feet, The well is
cased with 6 -inch heavy steel casing to a depth of 61 feet and cement grouted to a depth of 50 feet. The well
casing extends 12 inches above a 6 -foot by 6 -foot concrete pad and is equipped with a pitless adapter
assembly and sanitary well cap. A Red Jacket submersible well pump delivers 5.8 gpm at 490 feet TDH into
the existing 6,000 gallon hydropneumatic'tank located in the school water treatment building. The well yield
following a 48 -hour pump test was 6 gpm. An existing sample tap and totalizing flow meter, located in the
treatment building, will be used for this new well.
Page 2 - Albemarle County— Red Hill School Engineering Description Sheet
The treatment building, located adjacent to Well No. 3, houses the control end of a 6,000 - gallon
hydropneumatic tank, a solution feed chlorinator, corrosion control treatment, raw and finished water sample
taps and a meter with bypass piping downstream of the confluence of all three wells.
Treatment consists of a solution of soda ash blended with hypochlorite and separate orthophosphate (Aqua -
Mag) injection directly into the well discharge. Both foods are equipped with a 4 gpd metering pump. The
soda ash has a 40 gallon solution crock and the orthophosphate draws from a 5- gallon premixed solution
drum. Both metering pumps are wired in parallel with the well pump.
Design CgngcitX
Source /Pump Capacity: Well Numbers 1 and 2 - Unknown
Well Number 4 = 5.8 gpm (pump limited)
5.8 gpm x 2 ERCs /gpm = 11.6 ERCs
11.6 ERCs x 400 gpd /ERC = 4,640 gpd
Storage Capacity: 6,000 - gallon hydropneumatic tank
A 6,000 + 3 = 2,000 gallons effective storage
2,000 gallons - 200 gallons /ERG =10 ERCs
10 ERCs x 400 gpd /ERC = 4,000 gpd
Existing Condition: 300 students /staff
Therefor®, the design capacity of the Red Hill School waterworks is Iimited by storage to.a design capacity of
4,000 gpd.
