  1. Water Quality Survey of Alternative Safe Water Devices in Emergency Villages in Jessore District Md. Shamim Uddin Senior Chemist Asia Arsenic Network

  2. Location of Jessore Jessore

  3. Number of Alternative Safe Water Options and their Operational Status

  4. Location of Alternative Safe water Options in Emergency Response Villages DW PSF PWSS

  5. Introduce of Safe Water Option Dug Well with Filter Dug Well Pond Sand Filter Rain Water Harvester

  6. Pipe Water Supply System Using Surface Water Ecological Filter Water Supply Tap Supply Tank

  7. Objectives • To know the water quality of surface and sub-surface water based alternative safe water options in the rainy season. • To compare the water quality between rainy and dry season of dug wells.

  8. Tested Water Quality Parameter and Methodology

  9. Turbidity (Rainy Season) Excess Value of Bangladesh Standard : NTU<10

  10. Ammonium (Rainy Season) Excess Value of Bangladesh Standard : <0.64 mg/l

  11. Iron (Rainy Season) Excess Value of Bangladesh Standard : < 1.0 mg/l

  12. Manganese (Rainy Season) Excess Value of Bangladesh Standard : < 0.1 mg/l

  13. Arsenic (Rainy Season) Excess Value of Bangladesh Standard : < 0.1 µg/L

  14. Comments • The concentration of Arsenic, Iron, Manganese and turbidity were found relatively high in rainy season in Dugwell water. • The concentration of Ammonium was found relatively low in Dugwell water in rainy season

  15. Fecal Coliform (Rainy Season) Excess Value of Bangladesh Standard : < 10 cfu/100ml

  16. Bacteriological Contamination of Dugwell with Filter and Dug Well with Exceeding Bangladesh Guideline Value

  17. Water Quality of Pond Sand filter

  18. Comments • Dugwell and PSF were found highly fecal contaminated, but Dugwell is more serious. • We could not find out effectiveness of site selection of Dugwell in this study. • Sand filter seems effective to reduce the Fecal contamination, but not enough. • Chlorination is also necessary to produce Bacteriological safe water for dugwell with filter as well as PSF.
