Augusta CIP - Groundwater Treatment Plant No; 4 Wellfield
Larry,
As discussed and requested, we have obtained some pricing from Graves Well Drilling to perform aquifer testing in the
proposed Groundwater Treatment Plant NO.4 area. Graves was chosen for their demonstrated capabilities for well
installation, well development, and aquifer testing. They also provide a very good database of information about the local
aquifers from the experience in the area.
Graves has proposed the following:
. Testing of Existing Production Well #127 - They will remove the permanent pump from the well, conduct a video
inspection of the well interior, isolate the lowest screen section with inflatable packers, install a temporary pump and
operate it at 100 - 200 gpm to collect water samples from the isolated screened section. They will repeat this process
of isolating, pumping, and sampling for each of the six screened zones within the well. A full spectrum water quality
analysis (or a limited analysis based upon our request) will be run on the samples taken from each of the screened
sections. Once the sampling and analysis is complete, Graves will reinstall the permanent pump. The intent of the
isolation of the screened sections is to determine what specific screened section any particular problems are coming
from. .
. Installation of one 4" or 6" test well - Graves will drill and conduct geophysical logging of the test bore hole to
approximately 700 BGS. Once completed, they will drill and construct a well to 650' total depth with 160' of screens.
They will develop the well, then isolate the determined screened intervals (4 included) as with the existing production
well. The difference between the 4" and 6" wells is that only 5 - 10 gpm can be pumped from the 4" while 50 - 60 gpm
can be pumped from the 6" well. The higher pumping rate will more closely approximate the flow from the well. A full
spectrum water quality analysis (or a limited analysis based upon our request) will be run on the samples taken from
each of the four screened sections.
The proposed cost for this work i~ as follows:
Total Estimated Cost
$30,500
$21 ,000 (full spectl umirr6 ZOlles @ $3,500/zolle)
$79,500
$14,000 (full spectrum in 4 zones @ $3,500/zone)
$145,000
. Existing production well testing
-.----Water Quality At,alysis fr011l existillg well
. New 6" well
. Water Quality Analysis from new well
The proposal does not include clearly necessary for the new well location. Clearing and access won't likely be difficult
given the conditions in the area.
Please let me know how you wish us to proceed. I'll have Rob check on the schedule for completing the work since the
proposal does not address this.

DESCRIPTION
Following are estimates for various testing of aquifers for the Augusta-Richmond Utilities nt the area
referred to RS the "Kimberly-Clark Well field":
A Testing of Existing Production Well # 127: EstimRte to remove permanent pump from
well, conduct video inspection of well interior, isolate lowest screen section with inflatable
packers, install temporary submersible pump and operate at approximately 100-200 GPM in
order to coUect Wl\ter snmples (:Il1:1lysis by others), and check flow I drllwdown of screened
area. Repeat isolation, pumping, nnd amtlysis procedme for total of six screen zones in well.
Reinstllll permanent pump andprep:\[e to opemte into system.
$ 30,500.00
13. four Inch Test Well: E!ltiI11ll.te to chill and conduct geophysical logging of the test bote hole

As noted above, cl::1emical analyses from the various screen zones are not included in this estimate.
However, for reference purposes, a full analysis of water from a new well as required by GAEPD is
approxllnately $3,000.00 - 3,500.00. The project scope would include sampling from each isolated
screen zone, but "full" analyses may not be necessaty from each sample.
Cbtl-i.ng of area(s), ingress and egress is to be provided by others and is not included in these
estimates. Unit prices for lesser/greater depth(s), screen sections, screen lengths, pumping tests, etc.
can' be furnished prior to awardoE the project.
Thank you for your interest and for considering Graves for the project. Please give me a call at your
convenience to discuss this proposaL

RE: Augusta CIP - Groundwater Treatment Plant No, 4 Wellfield
Reecieved a fax from Graves yesterday noting that the work associated with the existing well would take (4) weeks to
complete and the remainder of the work would take up to (4) months to complete. He did note that the work at the existing
well could be done concurrent with that of the new well.
So the long and short of it, it will take approximately four months to complete. There is approximately 3 to 4 weeks in the
process where no progress on site will be completed. This time is for sizing of the pump and recieving the equipment to
install.
We also know that the results of the testing can very dependent upon the tests required.

Rob,
Could you find out how long it is estimated to take to complete the work once they are started?

Graves indicated that they would be in a position to begin work on the existing well within three weeks of
notification if not sooner.
