1
Arsenic Contamination of Groundwater in Ghazni an Maidn Wardak Provinces of Afghanistan
21, June, 2016 Eng. Hassan Saffi
2
Outline Afghanistan Distribution pattern of Arsenic concentration in
Finding Arsenic contamination in DWPs of Afghanistan Distribution pattern of Arsenic concentration in the DWPs of study area High Arsenic content DWPs and possible health impact Hydro-Chemistry trend and other water quality concern elements Recommendation
4
Arsenic and other trace element contamination may be concern due to availibilit of source minerals in Afghanistan
5
Peoples using high Arsenic content drinking water
in Panjsher province of Afghanistan
8
Recent Q: Gravel, Sand, Silt and Clay
Late- Recent Q: Gravel, sand, Silt clay, clay and conglomerate Late Q: Gravel mixed with sand, silt and clay, conglomerate and clay Middle Q: Conglomerate, sand with sand and silt and clay Oligocene: Phase 2, Granodiorite Eocene: Dunit, peridotite and serpentines Late Permian: Limestone, dolomite, marl, Carboniferous-Earl Permian: Siltstone, sandstone, shale, marfic volcanic Late Devonian: Siltstone, sandstone and limestone Middle Proterozoic: shiest, gneiss, quartz, marble and amphibolites
9
Arsenic contamination in the study area
Arsenic contamination is mostly Geologic occurrence Distribution pattern of Arsenic concentration in the DWPs is irregular. Arsenic concentrations ranged mg/L No clear clinical information about health effect of using high As content DW
10
Ghzni city with human population density
and high Arsenic content drinking water
13
Time series arsenic concentration values variation
14
Arsenic concentration levels in Surface water
0.016 mg/L 0.021 mg/L
15
Groundwater major ions chemistry of Chazni city
16
Groundwater major ions chemistry of Khwaja Umary district
17
Hydro-Chemistry model of Study area
19
Recommendation Enhance capacity building of WASH sector
Construct the DWPs in regard technical hydro-geological and WQ consideration. Encourage practical research for availability of alternative WSs Search cost effective technology for removal of Arsenic content drinking water
