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.

RE: Atluifer Testing nen I-Iorseshoe 1\<.1,& r-ligbwny 56. 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.

RECEIVED: 10/30/01 ;8:29;" ->CH2M HILL; #109; PAGE 3 " Oat' 30 01 09:39a GRAVES 8034719211 p.3 '\ 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 2 '" , Davls, Soh/eL T From: Sent: To: Cc: Subject: Lorentz, Rob/ATL November 09, 2001 8:38 AM Davis, Bob/CL T Scott, Larry/A TL 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. --Original Message-- From: Davis, Bob/CL T Sent: November 01, 2001 2:54 PM To: Lorentz, Rob/ATL Cc: Scott, Larry/ATL Subject: RE: Augusta CIP - Groundwater Treatment Plant NO.4 Wellfield Rob, Could you find out how long it is estimated to take to complete the work once they are started? -Original Message--- From: Lorentz, Rob/ATL Sent: November 01, 2001 2:41 PM To: Davis, Bob/CL T; Scott, Larry/A TL Subject: RE: Augusta CIP - Groundwater Treatment Plant NO.4 Wellfield Graves indicated that they would be in a position to begin work on the existing well within three weeks of notification if not sooner. ----Original Message---- From: Davis, Bob/CL T Sent: November 01, 2001 12:21 PM To: Scott, Larry/ATL Cc: Lorentz, Rob/ATL Subject: 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.
