Sampling water and its analysis results with some comments are as below: a) Desalinated water from existing facilities in Praia and Santa Cruz - Quality is generally within or close to the allowable level as drinking water -Cl- and Boron contents in Praia are slightly higher than WHO guideline b) Beach well water for the existing plants in Praia and Santa Cruz - No serious issue is found c) Ground water near the candidate sites of the planned water distribution - Quality of the water is within allowable level as drinking water - Nitrate, Total Coliform and Total Hardness should be further investigated d) Sea water around the candidate sites for the planned desalination facilities - No serious issue for RO desalination application is found - Ordinary pre-treatment is required for RO desalination - Analysis result was applied to the planned facility design 6 2-2 Sampling Location and Desalinated Water Current Desalinated Water Analysis Sample Praia St. Cruz Location SP 1-1 Sa SP 1-2 SS 1-1 Dringking Water Regulation mplin g No. 1-1 SS 1-2 1-2 Analysis Item Range Range WHO EU Japan Item Unit Temperature °C 16.4 ~ 19.1 24.1 ~ 24.2 pH - 6.4 ~ 7.4 at 21 °C 6.0 a 20 °C - 6.5 ~ 9.5 5.8 ~ 8.6 Conductivity ȝS (cm) 940 ~ 1,100 at 25 °C 220 ~ 230 at 25 °C 2,500 TDS mg/l 770 ~ 790 160 ~ 1801,000 5,000 200~500 Tubidity NTU <0.3 (LQ) - 1 (Max 5) - <2 deg Total Hardness mg(CaCO3) 71.1 <9.6 (LQ) - - <300 Chloride mg (Cl-)/l 320 ~ 800 64 <250 <250 <200 Boron mg (B)/l 0.65 ~ 0.69 <0.05(LQ) ~ 0.51 <0.5* <1.0* <1.0* Total Coliform ufc/100ml 0 0 Bacteria Count 7 2-3 Ground Water Analysis 4) Sao 7) Ribeira S 3) Assomada 6) Sao ample L 1)Sao Miguel 2) St. Cruz Lourenco dos 5) Tarrafal Grande de 8) Praia ocation and Picos Domingos Orgaos Santiago FBE-146 FT-186 FT-145 FBE-129 FBE-153 FBE-145 FBE-58 Dringking Water Regulation FT-09 FBE-116 FT-21 SST-04 FBE-156 FBE-205 58-09 FT-202 Samplin FT-47 FBE-161 FT-23 FBE-131 FT-81 g No. FBE-188 58-01 FBE-1A FT-59 FBE-100 FT-80 FBE-113 PT-29 FBE-112 FT-171 FT-63 FBE-117 FT-84 FST-24 FT-208 Analysis Item Range Range Range Range Range Range Range Range WHO EU Japan Item Unit Temperature °C 26.1~26.8 24.3 ~ 28.8 26.0 ~ 28.7 26.2 ~ 28.1 26.0 ~ 28.4 25.5 ~ 28.2 27.5 ~ 27.8 26.8 ~ 30.6 7.5 ~ 8.5 7.2 ~ 7.8 7.2 ~ 8.1 7.4 ~ 7.7 7.9 ~ 8.2 7.0 ~ 8.0 8.0 ~ 8.2 8.2 ~ 8.4 pH - - 6.5~9.5 5.8~8.6 at 22 °C at 20 °C at 20 °C at 22 °C at 25 °C at 23 °C at 22 °C at 24 °C <0.3(LQ) ~ <0.3(LQ) ~ <0.3(LQ) ~ <0.3(LQ) ~ <0.3(LQ) ~ Tubidity NTU 0.3(LQ) ~ 1.55 <0.3 (LQ) <0.3 (LQ) 1(Max 5) - <2 deg 0.62 0.68 0.79 0.72 0.41 Nitrate mg(NO3)/Ll 1.0(LQ) ~ 73.9 5.6 ~ 54.4 31.0 ~ 71.6 <1.0 ~ 54.4 12.4 ~ 16.6 <1(LQ) ~ 54 12.3 ~ 16.1 10.6 ~ 24.8 <50 <50 <10 <0.01(LQ) ~ <0.01(LQ) ~ Nitrite mg(NO )/l <0.01 (LQ) <0.01 (LQ) <0.01 (LQ) <0.01 (LQ) <0.01 (LQ) <0.01 (LQ) <3 <0.5 <0.05 2 0.02 0.21 Chloride mg (Cl-)/l 78 ~ 220 59 ~ 300 37 ~ 85 96 ~ 200 43 ~ 92 120 ~ 230 42 ~ 85 42 ~ 130 <250 <250 <200 <0.05(LQ) ~ Boron mg (B)/l 0.05 ~ 0.14 0.06 ~ 0.13 0.05 <0.05 ~ 0.09 <0.05 ~ 0.06 0.07 ~ 0.12 <0.05(LQ) <0.5* <1.0* <1.0* 0.07 Fluorine mg (F)/l <0.5(LQ) ~ 2.2 <0.5(LQ) ~ 0.6 <0.5 (LQ) <0.5 (LQ) <0.5 (LQ) <0.5 (LQ) <0.5 (LQ) <0.5 (LQ) <1.5 <1.5 <0.8 Total Coliform ufc/100ml 0 ~ 130 0 ~ 610 92 ~ 3,400 0 ~ 576 0 ~ 3,600 0 ~ 16 38 ~ 1,200 31 ~ 36 Bacteria Count Standard Plate ufc/ml 0 ~ >300 0 ~ >300 0 ~ 36 0 ~ 28 0 ~ >300 0 ~ 40 83 ~ 89 0 ~ 82 Count Bacteria Fecal Coliform ufc/100ml 0 0 ~ 119 0 ~ 5,800 0 ~ 19 0 ~ 140 0 ~ 35.2 11 ~ 83 0 ~ 40 Bacteria Count <60(LQ) ~ <60(LQ) ~ 60(LQ) ~ Iron ȝg (Fe)/l <60 (LQ) <60(LQ) ~ 130 <60 (LQ) <60 (LQ) <60 (LQ) <300 <300 <300 <93(LQ) 100 1,900 Total Hardness mg(CaCO3) 11.7 ~ 497.7 189.7 ~ 575 98. ~ 148 149 ~ 418 96 ~ 138 200 ~ 770 111 ~ 136 84.1 ~ 217.1 - - <300 Arsenic ȝg (As)/l <1(LQ) ~ 12 <1 (LQ) <1 (LQ) <1 (LQ) <1 (LQ) <1 (LQ) <1 (LQ) <1 (LQ) <10 <10 <10 Cadmium ȝg (Cd)/l <0.5 (LQ) <0.5 (LQ) <0.5 (LQ) <0.5 (LQ) <0.5 (LQ) <0.5 (LQ) <0.5 (LQ) <0.5 (LQ) <3 <5 <10 Mercury ȝg (Hg)/l <0.1 (LQ) <0.1 (LQ) <0.1 (LQ) <0.1 (LQ) <0.1 (LQ) <0.1 (LQ) <0.1 (LQ) <0.1 (LQ) <1 <1 <0.5 Cr+6 ȝg (Cr)/l <2 (LQ) <2 (LQ) <2(LQ) ~ 4 <2 (LQ) <2 (LQ) <2(LQ) ~ 6 4 3 ~ 7 <50 <50 <50 Lead ȝg (Pb)/l <5 (LQ) <5 (LQ) <5 (LQ) <5 (LQ) <5 (LQ) <5 (LQ) <5 (LQ) <5 (LQ) <10 <10 <10 Manganese ȝg (Mn)/l <4(LQ) ~ 48 <4 (LQ) <4 (LQ) <4(LQ) ~ 80 <4 (LQ) <4 (LQ) <4 (LQ) <4 (LQ) <400 <50 <50 8 2-4 Geotechnical Survey - 3 bore holes for SWRO facility - 20 trial pits for Transmission line - 4 laboratory tests for construction Survey Results are under review, But no critical issues are found at moment. Actual survey was conducted by Tecnasol, Portugal. 9 3-1 Population & Water Demand in 2020 Horizon of population in 2020 of the project targeted year was assumed to be about 370,566 persons in Santiago island in PR/R, but the horizon was newly assumed to be 355,319 persons by the latest Institute Nacional de Estatistics (INE). The ratio of urban area to rural area was also newly assumed to be “60 to 40” instead of “66 to 34” in the island. Water consumption rate was also re-estimated, and summarized as below: Urban Rural With public pipeline connection 150 80 Without public pipeline connection 50 50 For hotel user (tourist) 300 300 (unit: liter/day/person) 10 3-2 Water Demand and Production in 2020 㪪㫆㫌㫋㪿 㪥㫆㫉㫋㪿 㪩㫀㪹㪼㫀㫉㪸 㪪㪸㫆 㪪㫆㫌㫋㪿㩷㫋㫆㫋㪸㫃 㪪㪪㩷㪻㫆 㪪㪸㫅㫋㪸 㪪㪸㫆 㪥㫆㫉㫋㪿㩷㫋㫆㫋㪸㫃 㪫㫆㫋㪸㫃 㪻㪸㫋㪸㩷㫊㫆㫌㫉㪺㪼 㫀㫋㪼㫄㫊 㪧㫉㪸㫀㪸 㪫㪸㫉㫉㪸㪽㪸㫃 㪪㪸㫆㩷㪤㫀㪾㫌㪼㫃 㪪㪸㫅㫋㪸㩷㪚㫉㫌㫑 㪞㫉㪸㫅㪻㪼 㪛㫆㫄㫀㫅㪾㫆㫊 㪤㫌㫅㪻㫆 㪚㪸㫋㪸㫉㫀㫅㪸 㪣㫆㫌㫉㪼㫅㪺㫆 㪸㪅 㪫㪸㫉㪾㪼㫋㩷㪰㪼㪸㫉㩷㩿㪉㪇㪉㪇㪀㩷㪧㫆㫇㫌㫃㪸㫋㫀㫆㫅㩷㩿㫇㪼㫉㫊㫆㫅㪀 㪈㪌㪎㪃㪐㪎㪏 㪈㪈㪃㪌㪍㪉 㪈㪎㪃㪊㪊㪈 㪈㪏㪍㪃㪏㪎㪈 㪉㪏㪃㪌㪎㪎 㪉㪈㪃㪈㪊㪎 㪈㪊㪃㪈㪌㪎 㪌㪏㪃㪊㪉㪈 㪊㪍㪃㪈㪇㪉 㪈㪈㪃㪈㪌㪋 㪈㪍㪏㪃㪋㪋㪏 㪊㪌㪌㪃㪊㪈㪐 㪠㫅㫊㫋㫀㫋㫌㫋㪼㩷㪥㪸㪺㫀㫆㫅㪸㫃㩷㪻㪼㩷㪜㫊㫋㪸㫋㫀㫊㫋㫀㪺㪸㩷㩿㪠㪥㪜㪀 㪸㪈 㩷㩷㪄㩷㪬㫉㪹㪸㫅 㪈㪌㪌㪃㪍㪇㪐 㪈㪃㪎㪋㪍 㪉㪃㪎㪎㪉 㪈㪍㪇㪃㪈㪉㪎 㪐㪃㪎㪈㪎 㪎㪃㪊㪐㪏 㪈㪃㪎㪎㪍 㪈㪏㪃㪍㪍㪊 㪈㪋㪃㪋㪋㪈 㪉㪃㪉㪊㪈 㪌㪋㪃㪉㪉㪍 㪉㪈㪋㪃㪊㪌㪊 㪠㪥㪜 㪸㪉 㩷㩷㪄㩷㪩㫌㫉㪸㫃 㪉㪃㪊㪍㪐 㪐㪃㪏㪈㪍 㪈㪋㪃㪌㪌㪐 㪉㪍㪃㪎㪋㪋 㪈㪏㪃㪏㪍㪇 㪈㪊㪃㪎㪊㪐 㪈㪈㪃㪊㪏㪈 㪊㪐㪃㪍㪌㪏 㪉㪈㪃㪍㪍㪈 㪏㪃㪐㪉㪊 㪈㪈㪋㪃㪉㪉㪉 㪈㪋㪇㪃㪐㪍㪍 㪠㪥㪜 㪹㪅 㪦㫍㪼㫉㪸㫃㫃㩷㪧㫀㫇㪼㫃㫀㫅㪼㩷㪪㪼㫉㫍㫀㪺㪼㩷㪚㫆㫍㪼㫉㪸㪾㪼㩷㩿㩼㪀 㪐㪐㪅㪇㩼 㪐㪇㪅㪇㩼 㪐㪇㪅㪇㩼 㪐㪌㪅㪇㩼 㪐㪇㪅㪇㩼 㪏㪇㪅㪇㩼 㪐㪌㪅㪇㩼 㪐㪌㪅㪇㩼 㪐㪇㪅㪇㩼 㪪㫋㪼㪼㫉㫀㫅㪾㩷㪚㫆㫄㫄㫀㫋㫋㪼㪼㩷㩿㪪㪘㪘㪪㪀 㫀㫅㩷㪉㪇㪇㪎 㪋㪎㪅㪊㩼 㪈㪇㪅㪐㩼 㪐㪅㪐㩼 㪍㪋㪅㪈㩼 㪌㪊㪅㪎㩼 㪈㪌㪅㪋㩼 㪋㪏㪅㪏㩼 㪎㪍㪅㪐㩼 㪋㪊㪅㪐㩼 㪠㪥㪜 㪺㪅 㪪㪼㫉㫍㪼㪻㩷㪧㫆㫇㫌㫃㪸㫋㫀㫆㫅 㪚㫆㫅㫅㪼㪺㫋㫀㫆㫅㩷㫉㪸㫋㫀㫆㩷㫀㫅㩷㪬㫉㪹㪸㫅㪃㩷㪻㪸㫋㪸㩷㪹㫐㩷㪠㪥㪞㪩㪟 㪈㪇㪇 㩼 㪺㪈㩷㪔㪸㩷㫏㩷㪹 㪦㫍㪼㫉㪸㫃㫃㩷㫇㫆㫇㫌㫃㪸㫋㫀㫆㫅㩷㫊㪼㫉㫍㪼㪻㩷㪹㫐㩷㫇㫀㫇㪼㩷㫅㪼㫋㫎㫆㫉㫂 㪈㪌㪍㪃㪊㪐㪏 㪈㪇㪃㪋㪇㪍 㪈㪌㪃㪌㪐㪏 㪈㪏㪉㪃㪋㪇㪉 㪉㪎㪃㪈㪋㪏 㪈㪐㪃㪇㪉㪊 㪈㪇㪃㪌㪉㪍 㪌㪌㪃㪋㪇㪌 㪊㪋㪃㪉㪐㪎 㪈㪇㪃㪇㪊㪐 㪈㪌㪍㪃㪋㪊㪏 㪊㪊㪏㪃㪏㪊㪐 㪚㫆㫅㫅㪼㪺㫋㫀㫆㫅㩷㫉㪸㫋㫀㫆㩷㩿㪬㫉㪹㪸㫅㩷㪫㫆㫋㪸㫃㪀 㪺㪉㩷㪔㩷㪸㪈㩷㫏㩷㪚㪦㪥㪜㩷㩼 㩷㩷㪄㩷㪬㫉㪹㪸㫅㪃㩷㫎㫀㫋㪿㩷㫇㫀㫇㪼㩷㪺㫆㫅㫅㪼㪺㫋㫀㫆㫅 㪈㪌㪌㪃㪍㪇㪐 㪈㪃㪎㪋㪍 㪉㪃㪎㪎㪉 㪈㪍㪇㪃㪈㪉㪎 㪐㪃㪎㪈㪎 㪎㪃㪊㪐㪏 㪈㪃㪎㪎㪍 㪈㪏㪃㪍㪍㪊 㪈㪋㪃㪋㪋㪈 㪉㪃㪉㪊㪈 㪌㪋㪃㪉㪉㪍 㪉㪈㪋㪃㪊㪌㪊 㪈㪇㪇㩼 㪺㪊㩷㪔㩷㪺㪈㪄㪺㪉 㩷㩷㪄㩷㪩㫌㫉㪸㫃㪃㩷㫎㫀㫋㪿㩷㫇㫀㫇㪼㩷㪺㫆㫅㫅㪼㪺㫋㫀㫆㫅 㪎㪏㪐 㪏㪃㪍㪍㪇 㪈㪉㪃㪏㪉㪍 㪉㪉㪃㪉㪎㪌 㪈㪎㪃㪋㪊㪈 㪈㪈㪃㪍㪉㪌 㪏㪃㪎㪌㪇 㪊㪍㪃㪎㪋㪉 㪈㪐㪃㪏㪌㪍 㪎㪃㪏㪇㪏 㪈㪇㪉㪃㪉㪈㪉 㪈㪉㪋㪃㪋㪏㪍 㪚㫆㫅㫅㪼㪺㫋㫀㫆㫅㩷㫉㪸㫋㫀㫆㩷㩿㪩㫌㫉㪸㫃㩷㪫㫆㫋㪸㫃㪀 㪺㪋㩷㪔㩷㪸㪄㪺㪈 㪦㫍㪼㫉㪸㫃㫃㩷㫇㫆㫇㫌㫃㪸㫋㫀㫆㫅㪃㩷㪥㪦㪫㩷㫊㪼㫉㫍㪼㪻㩷㪹㫐㩷㫇㫀㫇㪼 㪈㪃㪌㪏㪇 㪈㪃㪈㪌㪍 㪈㪃㪎㪊㪊 㪋㪃㪋㪍㪐 㪈㪃㪋㪉㪐 㪉㪃㪈㪈㪋 㪉㪃㪍㪊㪈 㪉㪃㪐㪈㪍 㪈㪃㪏㪇㪌 㪈㪃㪈㪈㪌 㪈㪉㪃㪇㪈㪈 㪈㪍㪃㪋㪏㪇 㪏㪏㩼 㪺㪌㩷㪔㩷㪸㪈㪄㪺㪉 㩷㩷㪄㩷㪬㫉㪹㪸㫅㪃㩷㫎㫀㫋㪿㫆㫌㫋㩷㫇㫀㫇㪼㩷㪺㫆㫅㫅㪼㪺㫋㫀㫆㫅 㪇 㪇 㪇 㪇 㪇 㪇 㪇㪇㪇㪇 㪇 㪇 㪺㪍㩷㪔㩷㪸㪉㪄㪺㪊 㩷㩷㪄㩷㪩㫌㫉㪸㫃㪃㩷㫎㫀㫋㪿㫆㫌㫋㩷㫇㫀㫇㪼㩷㪺㫆㫅㫅㪼㪺㫋㫀㫆㫅 㪈㪃㪌㪏㪇 㪈㪃㪈㪌㪍 㪈㪃㪎㪊㪊
