•     Tn understand Aquifer productivity and water quality variations in depth and lateral
’ To acquite subsurface data to calibrate die geophysical investigation results
*     To Obtain Aquifer parameters
The test wells  are drilled sl the major fan areas  in the study  area, moreover the depih nf the Wells  were shallow Id deep depending on the depth for Fresh aid Sait waler interface and the fan thickness  . The minimum depth of test wdl is  92m ( DTW-Jft which is  drilled north east of GeherU fan close to the sad plain and the maximum depth of test well Is  250m i.DTW-7 and DTW-9 ) drilled on Saba fan area.
The lea well drilling in lhe proposed mne sites  of the piojcct area wftS started in Ecb. 2012 TWO months  later after lhe signing of the Centrad i.e Dec. 2Q12. The main Cotiuacior is  Ettiwpduh BV Ethiopian branch and the Sub Contractor 15 Kaja ltaja Mineral and Expiation Techniques  Wt The contractual Lime for the drilling was  six  months  however due Io various problems  related to cuing supply  and iccces roads  the contract was  emended tor two months where a toial of xn test boreholes  (one extra lest borehole added with amcndmcnlsj are completed successfully.
The distribution of test boreholes  was  planned Ln lesL the potential of the major tan areas  of Asahuyc  , Musky, Gchenu ( North Musky) and Bckcrti ( South Musleyj and Saba fan areas.

Lil, Drilling
According   fo   the   contract   agreement,   the   target   depth   intended   tn   drill   is   250   m   on   average.   The drilling work id tpially carried out with Mud Rotary system. The drilling w&rk ii designed id drill
Up   to   150m   depth   with   L4   "   diameter   and   below   this   with   IG'1     diameter   for   the   installation   p|'
| IO ’and 6” diam. PVC casings.

The major drilling problems  encountered so far are Bit damaged repeatedly  due to very  hard boulders  of basement rucks  transported from western escarpment areas  and casing slacking in most of the test weils  which was  solved by  continuous  riming especially  for the deep boreholes in Norin Muslcy (DTW-4) due to hard meta-sedimentary rocks and intercalated thick clay in
Saba and Bckc ni fan (DT W-7 and DTW-6) tesL bore holes.
According to the contract, the drilling work was agreed io be carried out with 20'1 drilling bit for
the   upper   six   mcLer   soft   formaLinn   where   i?   “steel   surface   casing   is   installed   and   the   dolling   is 
»        II
continued with 34 "bit up to 15dm with the installation of 10“ casing and again drilling is continued to the bonom with id " bit where 6 " casing is  installed . For some boreholes  which are drilled up in 200-250m depth, this design is followed (DTW-2, DTW-4, DTW-7, DTW-9) .
However    there    arc    also    some    local    hydro-geological    conditions    where    the    drilling    wLth    large diameter is continued below 150 m for Some depth like DTW-4, DTW-2, DTW-6 and DTW-H-
In the center of the alluvial fan area, [he drilling has  encountered coarse gravel and sand formation up io 160m lDTW-3 and DTW-2 in Gchcrtu fanj with the intercalation of clay  at different depth, but below 160 or 170 meter the drilling has  encountered basement rocks  of Meta sedimentary and mem-volcanic rocks.
1.1,2,      Lithologic and Boreholt Geophysical Logging
Rock  cuttings  were: collected at 2m interval and where there were lithologic  variations  during drilling in all test Wells. Rock  cuttings  and sediments  were described properly  and waler bearing zones  were identified Prior w casing installation, geophysical borehole loggings  like resistivity  , natural gamma , porosity, conductivity  , caliper, and temperature logging? were conducted to identify the water-bearing formation and lithologic unit variations through geophysical signature

so  as   to  place  the  screen  in  appropriate  position  where  adequate  water  can  pass  through  it  and  io characterize di Herein formations.
1.2.3.     Casing installation
Permanent casings  PVC and water level observation pipes  were installed at the completion of drilling As  per the design 10 'L PVC casings  were installed Up TO 150m and 6 " PVC casings  up to 250m for lest boreholes  like DTW-7 and DTW-9. For some lest holes  Like [>TW-4, DTTW-2, DTW-6 and DTW-8 installation of 10 “ PVC casing was  continued below 150m depth depending On the prevailing hydro geologic  condition. On the other hand drilling was  stopped before the target depth to avoid salt intrusion from lower beds  in some EeSL holes  like DTW-], DTW-3 , DTW-5and DTW-10
1.2.4.     Gravel Packing and Well Completion
For   all   Completed   wells,   the   annular   spaces   were   packed   with   properly   washrd   and   rounded   river gravel of 6-9 mm size.
I. ,2-5. Pumping Teat
Prior   to   the   commencement   of   step   draw   down  test,   provision   tests   were  conducted   at   least  for  I- 2hrs io estimate the discharge rate for step and constant rate pumping tests.
To evaluate well efficiency  and to determine the discharge rate for the constant test, step draw down tests  were conducted only  fur DTW-4 since the draw down is  minimum fen the other tested boreholes.
Constant rate pumping tests  were conducted for the completed lest wells  to know the aquifer hydraulic  paramtiers  of the mapping wells. Submersible pump with maximum discharge capacity  of 50 l/s  were used io conduct the tests. The constant pumping test was  4K hrs.Thc discharge obtained from the pumping test ranges  from 5 l/s  - ID l/s  ( for DTW-2 . DTW-4 and DTW- 5 ) Lo more than 50 l/s  for DTW-1 DTW-3 and DTW-10 test holes  in Musky  and Gcheriu fan areas  with minimum draw- down. This  indicates  thaL Lhe wells  can yields  more than this yields if higher pumps were used.

In the whole course of dr illing, drill cuttings  were collected at 2 meters  fixed interval to describe both ihc  lithology  of formation samples  penetrated by  the borehole and the stratigraphical succession. Samples were desenbed properly and water bearing zones were identified.
For the purpose of litho logical lugging, formation samples  that were collected and provided at every  two linear meters  interval were described using ihc  aid of hand lens. In general the stratigraphic  sequences  encountered throughout the penetrated depth of the well are fine sand, gravel and coarse sand. The possible water bearing formations are gravel and coarse sand.

2.1.6 Casing and Observation Pipe installation and Gravel Packing
Casing arrangement is  done after considering geophysical logging, formation samples  (drill culling), penetration rate in order to identity' the water bearing format i ons and arrange the screen and bland production casings  so as  to set the screen casings  against the aquifer portion of the well Since Lhe proper positioning of the screen and bland casings ensure the fret passage of the ground water flow from die aquifer to lhe well and thereby  maximize (he amount of water withdrawn from the wellF special care was given to lhe appropriate placing of the screens.
Then after, well is  cleaned to maxc  ready  for installation of production casing. Installation of IO" inches  PVC producuon casing with screen setting pursuant: io the water bearing formation were performed.

LIJI Cementing and Grouting
Grouting was done both nerween the wall of the borehole and the surface cuing and in between the surface casing and production The cement grout provide 3 seai which is readily placed and develop the strength to contain load, hold casing firmly in position and the most important thing is to prevent the seepage of surface water in to the well
The grouung between the surface casing and wall of the borehole is  done just after the installs ion of six maters steel Surface casing The grouting between the production casing and the conductor cuing is done after the gravtj packing and development which is six meter below the surface and half a meter above the surface
2.1.12 Well Head Construction
The final part of the well construction is the well head Well bead was done according to the specified Design as it out line m the contract agreement in actual fact to protect the stick up above ground from breakage and movement during pump installation including capping of rectangle is constructed But most importantly to avoid the rescue of pollution and for sanitary purpose with special care is taken for the mixing ratio and quality of sand, water, cement and aggregate used for the construction of the well head with 1 tn x 1 m x 0 5m dimension

2.1,13 Borehole camera inspection
Borehole camera inspection is done to have visual record of the well for the Mure rchabllilai ion
and pump installation problem. This borehole camera is designed also to have a partial side view The borehole camera inspection was performed by downward looking accompanied by an appropriate light source, The recorded data of lhe inspected wells is submined on with DVD tape
by the contractor with this report.
2.1.14   Well capping
After the completion of well head construction, we sealed and capped the well with 6mm thick steel plale of lhe same diameter as the conductor casing was wtlded as security measure to assure that no foreign object fall into the well before the well starts giving the intended service. On the middle of well cap half inch threaded opening is prepared to send in the dip mater for checking she water table anytime. The Lrcadedi opening is closed with Lhreaded half inch cap
2.1.15 Conclusion and Recommendation
After diligent examination of the drilling cutting and result of constant test, the main aquifer in the area is coarser sand and gravel. The whole construction works i.e. the drilling, developing installation of casing and sanitary protections had been performed.
The  screen  production  casings  are  set  to  be  against  aquifer  portion  of  the  well.  This  was confirmed from examination of the drill curlings and electrical Logging.
According to the agreement, the proposed, total drilling target depth is 250m (he intended, to drill with in ±20% was 300m, however, the well is drilled up to a depth of 188m. Again from careful examination of casing arrangement and total draw* down observed in the well and aquifer position we recommended to set the pump position to be around at the depth of 100m.
As the laboratory chemical analysis show the water is grouped under the fresh water only the problem is sulphate (So4) concentration which is not advised to drink it without treatment but for solution mining to extract minerals will not be problem. So as to see from all perspective the Gchartu fan looks  good with further investigation it can give additional wells  for lhe solution mining process.

Casing arrangement is  done after considering geophysical togging, formation samples  (drill cutting), penetration rate in order lo identify  the waler bearing formations and arrange the screen and blind production casings  so as  to sei the screen casings  against the aquifer portion of the well Since rhe proper positioning of the screen and biind casings ensure the free passage of the ground water flow from the aquifer co the well and thereby  maximize the amount of water withdrawn from the well, special care was given to Lhe appropriate placing of the screens.
Then after, well is  cleaned lo make ready  for installation of production casing- Jnsia! lai ions  of JO” and 6*" PVC production casing with screen setting pursuant to the water bearing formation were performed

XXII Cernraling and Grouting
Grouting was done both between the wall of the borehole and the surface casing and in between the surface casing and production The cement grout provide a seal which is  readily  placed and develop the strength to contain loud. hold casing firmly  m position and the mosi important thing ia to prevent the seepage of surface water m to the well
The grouting between the surface casing and wall of the borehole is  done just after the installation of six  maters  steel surface casing The grouting between the production casing and the conductor casing is done after the gravel packing and development which is six meter below the surface and half a meter above the surface

2 2.12 Well Head Construction
The final part of the well construction is  the well head. Well head was  dune according to the specified Design as  it out iint in the contract agreement in actual fact to protect lhe stick  up above ground from breakage and movement during pump installation including capping of rectangle is  constructed. But most importantly  to avoid the rescue of pollution and for sanitary purpose with Special care is  taken for the mixing ratio and quality  of sand, waler, cement and aggregate used for the construction of lhe well head with I m x Im x U.Sm dimension.
2.2,13 Borehole camera inspection
Borehole camera inspection is done to have visual record of the well for the future rehab il italion and pump installation problem. This borehoie camera is designed also to have a partial side view, The borehole camera inspection was  performed by  downward looking accompanied by  an appropriate Light source. The recorded data of lhe inspected wells is submitted on with DVD tape by the contractor with this report.
2-2-14 Well Capping
After the completion of well head construction, wc  scaled and capped the well with 6mm thick steel plate of the same diameter as  the conductor casing was  welded as  security  measure to assure that no foreign object fall into the well before the well starts  giving the intended service. On the middle of well cap half inch threaded opening is  prepared to send in the dip mater for checking the water isdIc anytime. The treaded opening is closed with threaded half inch cap.
2-2.15 Conclusion and Recommendation
After diligent examination of lhe dnlling culling and result of constant test, the main aquifer in the area is  coarser sand and gravel. The whole construe Lion works  i.e. lhe dnlling, developing installation of casmg and sanitary protections had been performed.
The  screen  production  casings  arc  set  to  be  against  aquifer  portion  of  lhe  well.  This  was confirmed from examination ot the drill cuttings and clectncai logging.

According la lhe agreement, (he proposed total drilling target depth is  250m the intended to drill with an ±20% was  300m, however, lhe well is  drilled up lo a depth of 223m. Again from careful exami nation of casing uirangemcnt and lotaJ  draw down observed in the well and aquifer position we .recommended io set the pump positron to be around at the depth of 155m
In general, lhe value of lhe aquifer parameters  shows  lhai (he area has  high ground waler potential, the chemical quality  of the well water is  Braekish this  is  not recommend for any  other man mineral extraction and oil and gas  production. So this  well will only  be used for solution mining widen is  pianned for the future in the area and funhcT detail, study  has  to be done to delineate which part of Gchenu fan is saiine

2.3.6 Casing and Observation Pipe installation and Gravel Packing
Casing arrangement is  done after considering geophysical logging, formation samples  (drill culling), penetration rate in order to identify  the water bearing formations  and arrange the screen and blind pToductLon casings  so as  to set the screen casings  against the aquifer portion of the well Since the proper positioning of (he screen and blind casings ensure the free passage of the groundwater flow from (he aquifer to the well and thereby  maximize the amount of water withdrawn from the well, special care was given to the appropriate placing of the screens.
Then after, well is  cleaned to make ready  for installation of production casing Installations  of 10’* PVC production casing with screen setting pursuant to the water bearing formation were performed.

2.111 Cementing and Grouting
Grouting was done both between the wall of the borehole and the surface casing and tn between ibe surface casing and production. The cement grout provide a seal which is readily placed and develop the strength io contain load, hold casing firmly in position and the most important thing is to prevent the seepage of surface water m to the well
The grouting between the surface casing and wall of the borehole is done just after the installation of six maters steel surface casing The grouting between the production casing and the conductor casipg is done after the gravel packing and development which is six metes below ihe surface and half a meter above the surface

1.3.12 Well Head Construction
The final part of the well construction is the well head. Well head was done according to the specified Design as it out line in the contract agreement in actual fact to protect- the stick up above ground from breakage and movement during pump installation including capping of rectangle is  constructed But most importantly  io avoid the rescue of pollution and for sanitary  purpose with special care is  Lai.cn for the mixing ratio and quality of sand; water, cement and aggregate used for the construction of the well head with lm k Im x0.5m dimension.
2.3.13  Burt ho it omen inspection
Borehole camera inspection is  done to have visual record of the well for the future rehabilitation acid pump installation problem. This  borehole camera is  designed also to have a partial side view lhe tort hole camera inspection was  performed by  downward looking accompanied by  an appropriate light source. The recorded data of the inspected wells  is  submilled cm with DVD tape by  the contractor with this report.
2.3-14 Well Capping
After the completion of well head construction, we sealed and capped the well with fimm thick sieci
plaie of the same diameter as the conductor casing was welded as security measure to assure that no
foreign object fall into lhe well before the well starts giving the mlunded service. On lhe middle of
well cap half inch dircaded opernng is prepared to send in lhe dip mater for checking the water (able
anytime. The treaded opening is closed with threaded half inch cap
2.3-15 Conclusion and Recommendation
After diligent examination of the drilling cutting and result of constant test, the main aquifer in the area is  coarser sand and gravel. The whole construction works  i.e. lhe drilling, developing installation of casing and sanitary protections had been performed
The  screen  production  casings  are  set  to  be  against  aquifer  portion  of  lhe  well.  This  was  confirmed frniii examination of the drill tunings and electrical logging.
According  to  rhe  agreement,  the  proposed  total  drilling  target  depth  is  250m  the  intended  to  drill  with in ±29% was 300m. however, the well is drilled up to a depth of cXhn Again from careful

2.4.4 Casing and Observation Pipe instillation and Gravel Packing
Casing arrangement is  done after considering geophysical Logging, formation samples  (drill cutting), penetration race in order io identify  Lhe water bearing formations  and arrange She screen and blind production casings  so as  to set the screen casings  against she aquifer portion ol she well. Since the proper positioning of the screen and blind casings  ensure the free passage of the ground waler flow from the aquifer to lhe well and thereby  maximize lhe amount of water withdrawn from the well, special care was given to the appropriate placing of the screens.
Then after, well is  cleaned to make ready  for installation of production casing. Installations  of ] 0" and 6" PVC production casing with screen setting pursuant to the water bearing formation were performed

Grouting, was dune both between the wall of the borehole and the surface casing, and in between the surface casing and production The cement grout provide a seal which is  readily  placed and develop the strength to contain load, hold casing firmly  in position and the most important thin® is to prevent the seepage of surface water in to the well
The grouting between the surface casing and wail of the bocehole is  done just after the installation of six  maters  steel surface casing The grouting between the production casing and The conductor casing is done after the gravel packing and development which is six meter below (he surface and half a meter above the surface

The final pan of the well construction is the well head- Well head was done according to the specified Design IE 11 out line in the contract agreement in actual fact lo protect the slick up above ground from breakage and movement during pump installation including capping of rcclangle is  constructed. Hut most importantly  io avoid Lhe rescue of pollution and for sanitary  purpose with special care is taken for the mixing ratio and quality of sand: water. cement and aggregate used for the construction o£ the well head with Im x im x 0 5m dimension
2-4.14 Borehole camera inspection
Borehole camera inspection is done to have visual record of the well for the future rehabilitation and pump installation problem This  borehole camera is  designed also to have a partial side view. The borehole camera inspection was  performed by  downward looking accompanied by  an appropriate light source. The recorded dais  of the inspected wells  is  submitted on with DVD tape by  the contractor with this report.
2.4.15  Weil capping
After the completion of well head construction. we sealed and capped the well with 6mm thick steel
plate of the same diameter as rhe conductor casing was welded as security measure to assure that no foreign object fall into the well before the well starts giving the intended service. On rhe middle of
well cap half inch threaded opening is prepared to send in rhe dip mater for checking the water cable anytime. The Lttaded opening is closed with threaded haif inch cap.
2.4.16 Conclusion and Recommendation
After diligent examination of the drilling cutting and result of constant test, the main aquifer in the area is  coarser sand and gravel. The whole construction works  i.c. the drilling, developing installation of casing and sanitary protections liad been performed.
The  screen  production  casings  are  set  to  be  against  aquifer  portion  of  the  well.  This  was  confirmed from examination of the drill cuttings and electrical logging.
According IO the agreement, the proposed total drilling larger depth is 250m the intended to drill with in ±20% was 300m; however, lhe well is drill'd up to a depth of 2$0m Again from careful
final fl*port well Atcamplu.hrner.i Report of Musky i-ans 
artii [&aiiai^ ?c 14
L4?■■■aui wprits Dfiign jnd Superwior. Enterprise
examination of casing arrangement and total draw down observed in the well and aquifer posit recommended to set the pump position to be around at the depth of 155m.
As the laboratory chemical analysis show the waler is saline this is not recommend for an\ other mineral extraction and oil and gas production. So this well will only be used for solution mining which is planned for the future in the area. Il also recommended using bigger pump to determine the aquifer parameter because the one which we use is too small to make a drawdown.

2.5.5 J Geological Logging
!n the whole course of drilling, drill cuttings were collected al 2 meters fixed interval to describe bfflh the lithology  of formation samples  penetrated by  the borehole and the siraiigraphical succession. Samples were dcscrihcd properly and water bearing zones were identified.
For the purpose of lilho logical logging, formation samples that were collected and provided at every two linear meters interval were described using the aid of hand lens. In general the
suatigraphic sequences encountered throughout the penetrated depth of the well are fine sand, gravel, coarser sand and clay The possible water bearing formations arc gravel and coarser sand

2 5.6 Casing and Observation Pipe installation and Gravel Parking
r
Casing arrangement is  done after considering geophysical logging, formation samples  (.drill cutting), penetration rate in order to identify the water bearing formations and arrange the screen and blind production casings so as to set the screen casings against the aquifer portion of the well. Since the proper positioning of the screen and blind casings ensure the free passage ot the groundwater flow from [he aquifer to the well and thereby  maximize the amount of water withdrawn from the well, special care was given to the appropriate placing of the screens.
Then  afteT,  well  is  cleaned  to  make  ready for  installation  of  production  casing,  installations  of
V ] 0”  PVC  production  casing  with  screen  setting  pursuant  to  the  water  bearing  formation  were performed

2.5.13 Cementing and Grouting
Grouting was done both between the wall of the borehole and the surface casing and in between the surface casing and production The cement grout provide a seal which is readily placed and develop the strength to contain toad, hold casing firmly in position and the most important thing is to prevent the seepage of surface water in to the well
The grouting between the surface casing and wall of the borehole is  done just after the installation of six maters steel surface casing The grouting between the production casing and the conductor casing is done after the gravel packing and development which is six meter below rhe surface and half a meter above the surface
2.5.14 Well Head Construction
The final pan of the well construction is the well head Well head was done according to the specified Design as it out line in the contract agreement in actual fact to protect the stick up above ground from breakage and movement during pump installation including capping of rectangle is constructed But most importantly to avoid the rescue of pollution and for sanitary purpose with special care is taken for the mixing ratio and quality of sand, waler, cement and aggregate used for (he construction of the well head with 1 m x Im x 0 Sm dimension
2.5.15  Borehole camera inspection
Borehole camera inspection is done to have visual record of the well for the future rehabilitation
and pump installation problem This borehole camera is designed also to have a partial side view
final Report: Wei AccompiisJimr-nt Report of Musley fini and adpeent areas (OailolL 2014
17®Waler Wprks Denjn. and Supervision EmcrpftSf
The borehole camera inspection was  performed by  downward looking accompanied by  an appropriate light source. The recorded data of the inspected wells is submitted on with DVD tape by the contractor with this report.
2.5.16  Well Capping
After the completion of well head construction, we scaled and cupped the well with 6mm thick steel plate of the same diameter as the conductor casing was welded as security measure to assure that no foreign object fall into the well before the well starts giving the intended service. On the middle of well cap half inch threaded opening is prepared to send in the dip maicr for checking the water table anytime. The treaded opening is closed with threaded half inch cap.
2.5.17 Conclusion and Recommendation
After diligent examination of the drilling cutting and result of constant test, the main aquifer in the area is coarser sand and gravel- The whole construction works i.e, the drilling, developing installation of casing and sanitary protections had been performed.
The  screen  production  casings  are  set  to  be  against  aquifer  portion  of  the  well.  This  was confirmed from examination of the drill cullings and electrical logging.
According to the agreement, the proposed total drilling target depth is 250m the intended to drill with in ±20% was 300m; however, the well is drilled up to a depth of 152m, Again from careful examination of casing arrangement and total draw down observed in the well and aquifer position w recommended to set the pump position to be around al the depth of 130m
As the laboratory chemical analysis show the water is good except the sample analysis result which is taken at die binging shows hardness and so it ts recommended to identify why the hardness is not seen in the other samples.

2.6.5 Logging, EC and Temperature
2.6.5.1 Geological Logging
In the whole course of drilling, drill cuttings wctc collected at 2 meters fixed interval la describe both the lithology  of formation samples  peneLrated by  the borehole and the stratigraphical succession. Samples were described properly and water bearing zones were identified.
For the purpose of litho logical logging, formation samples iluit were collected and provided at every  two linear meters  interval were described using the aid of hand Jens. In general the stratigraphic sequences encountered throughout the penetrated depth of the well are coarser sand, clay and gravel. The possible water bearing format ions are gravel

Casing arrangement is  done after considering geophysical loggings  formation samples  (drill cutting),. penetration rate in order io identify  the water bearing formations and arrange the screen and blind production casings  so as  to sei the screen casings  againsi the aquifer pottiun oi the well. Since the proper positioning of the screen and blind casings ensure the free passage of the groundwater flow from lhe aquifer lo the well and thereby  maximize the amount of water withdrawn from the well, special care was given io the appropriate placing of the screens.
Then after, well is  cleaned to make ready  for installation of production casing- Installations  of 10” PVC production casing with screen setting pursuant co the water bearing formation were performed

2.6.9 Gravel packing
After the completion of casing installation the annular space between the wall of the well and the casing packed with 7mJgravel. The gravel is  clean, well rounded grains  of uniform size which ranges between 4-fimm and they are free from soluble materials.
2.6.10 Well Development
To remove the mud cake or drilling fluid film that coats the borehole and to increase the natural porosity  and permeability  of the formation in the vicinity  of the borehole, well development is carried out The well developed by air compressor, for 21 hours until die water become clean and sill/sand free.
2.6.11   Cementing and Grouting
Grouting was done both between the wall of the borehole and the surface casing and in between ihc surface casing and production. The cement grout provide a seal which is readily placed and develop the strength to contain loud, hold casing firmly in position and the most important thing is to prevent the seepage of surface water in to the well.
The grouting between the surface casing and wall of the borehole is  done just after die installation of six  maters  steel surface casing The- grouting between the production casing and the conductor casing is done after the gravel packing and development which is six meter below the surface and half a meter above the surface.
2,6.12   Well Head Construction
The final part of die weh ccmstruciion is  the well head. Well head was  done according to the specified Design as  it out line in the contract agreement in actual fact to protect the stick  up above ground from breakage and movement during pump installation including capping of rectangle is construe ted. But most importantly to avoid the rescue of pollution and for sanitary purpose with special care is  taken for the mixing ratio and quality of sand; waler. cement and aggregate used for the construction of the well head with Im x Im x 0.5m dimension.

2.6.13 Borehole camera Inspection
Borehole camera inspection is done io have visual record of the well for the future rehabilitation and pump installation problem. This borehole camera ls designed aJso to have a pan ial side view. The borehole camera inspection was  performed by  downward looking accompanied by  an appropriate light source. The recorded data of the inspected wells is submitted on with DVD tape by die contractor with this report
1.6.14 Well capping
After ihe completion of Well he:>d construction, we scaicd and capped the well with 6mm thick steel plate of the same diameter as  the conductor casing was  welded as  security  measure to assure that no foreign object fall into the well before the well starts  giving the intended service. On the middle of well cap half inch threaded opening is  prepared to send in the dip mater for checking the waler table anytime. The treaded opening is closed with threaded half inch cap.
2.6.15 Conclusion and Recommendation
After diligent examination of the drilling cutting and result of pre-luminary pumping test, the
area is highly weathered decomposed alluvial deposits and day. The whole construction works 
i e. die drilling, developing installation of casing and sanitary protections had been performed.
The screen production casings are set to be againsi aquifer portion of the well. This was 
confirmed from examination of the drill cullings and electrical logging.
According Co tile agreement, the proposed toul drilling target depth is 250m the intended to drill with m ±20% was 300m. however, the well is. drilled up to a depth of 160m.
During preliminary  rest the discharge was  very  small and creates  fast drawdown which is impossible to conduct pump rest with available higher pump on site to give 201/s with 100m head according to ilk- contract agreement specification.

2.7.6 Casing »nd Obscnaiion Pipe installation and Gravel Packing
Casing HJiangcmeni is  done after considering geophysical logging., formation samples  (drill culling), penetration rate an order to identify lhe water bearing formations arid arrange the screen and blind production casings  so as  to set the screen casings  against the aquifer portion of the well Since lhe proper positioning of lhe screen and blind casings ensure the free passage of the ground water flow from the aquifer U) the well and thereby  maximize die amount of water withdrawn from the well, special care was given to the appropriate placing of lhe screens 
Then  after,  well  is  cleaned  lo  make  ready  for  installation  of  production  casing.  Installation  of  10
inches  PVC  production  casing  with  screen  setting  pursuant  to  lhe  water  bearing  lormation  were performed

1,7 JI Cementing and Grouting
Grouting was done both between the wall of the borehole and the surface casing and in between the surface casing and production The cement grout provide a seal which is  readily  placed and develop the strength to contain load, hold casing firmly  m position and the most important thing is to prevent the seepage of surface water in to the well
The grouting between the surface casing and wall of the borehole is  done just after the installation of six  maters  steel surface casing The grouting between the production casing and the conductor casing is  done after the gravel packing and development which is  six  meter below the surface and half a meter above the surface
2.7.12 Wefl Head ConstraelMii
The final part of the well construction, is  the well, head Well head, was  done according to the specified Design as  it out line in the contract agreement in actual fact to protect the stick  up above ground from breakage and movement during pump installation including capping of rectangle is  constructed But most importantly  to avoid the rescue of pollution and for sanitary purpose with special care is  taken for the mixing ratio and quality  of sand, water cement and aggregate used for the construction of the well head with Im x Im x 0 5m dimension

installation of ca-SLng and sanitary protections had been perfonned
The  screen  production  casings  are  set  to  be  against  aquifer  portion  of  lhe  Well.  This  was confirmed front examination of the drill cuttings and electrical logging.
According 10 the agreement, Che proposed total drilling target depth is 250m the jmcndcd to drill
wilh in ±20% was 300m; however, lhe well is drilled up to a depth of 130m, Again from careful examination cf casing arrangement and total draw down observed in the well and aquifer

Dallol Area Groundwater Assessment Summary

Dallol Area Groundwater Initial Assessment Project

Project Overview

Client: Ministry of Water, Irrigation and Energy, Ethiopia

Contract Date: December 2012

Location: Dallol area, Afar National Regional State, Ethiopia

Purpose: Evaluate groundwater potential in Musley and adjacent fan areas

Key Findings

10 test wells drilled (DTW-01 to DTW-10) ranging from 91m to 250m depth
Wells located in major fan areas: Gehertu, Asabuye, Musley, Bekerti, and Saba
Yields varied significantly - from 2-3 l/s (low yield wells) to 50-60 l/s (high yield wells)
Water quality ranges from fresh to brackish/saline depending on location

Well Characteristics Summary

Well ID	Location	Depth (m)	Static Water Level (m)	Yield (l/s)	Water Quality
DTW-01	Gehertu	189	99.59	44	Fresh (high sulphate)
DTW-02	Gehertu	223	144.86	10	Brackish
DTW-03	North Gehertu	91	43.3	60	Brackish
DTW-04	Asabuye	261	132.8	10	Brackish
DTW-05	Musley	152	45.19	6	Fresh
DTW-10	Musley	130	79.28	50	Good quality

Methodology

The project involved:

Mud rotary drilling system with PVC casings
Lithologic and geophysical borehole logging
Gravel packing and well development
Pumping tests (preliminary, constant rate, and recovery tests)
Water quality analysis

Conclusions and Recommendations

Gehertu fan shows good potential with high yields (DTW-01 at 44 l/s)
Water quality varies - some wells have high sulphate content making them unsuitable for drinking without treatment
Recommend further investigation in Gehertu fan area for potential additional wells
Water suitable for solution mining despite high sulphate in some wells
