Name: Cameroon Water Data

 

Abstract: Some of the members of the Nursing/Engineering Department at Hope College set out to Cameroon, Africa to help improve drinking water quality and community health in developing communities.  Twenty-six cement filters were installed in or near homes in Cameroon.  These families have no electricity, no water distribution system, and get their water from year-round streams.  The filter contains a diffuser plate, fine sand, coarse sand, and gravel.  Many different variables were looked at including the topics of general observations, filter observations, microbiology observations, household practice observations, user perceptions, and water source observations.

 

Variables (column):

  1. ID Number (1-26)
  2. Filter Number
  3. Region (1=Ndzen Dzui, 2=Roovisem, 3=Tankuv, 4=Rosang)
  4. Age of Filter (weeks)
  5. Location of Filter (0=Outside Home, 1=Inside Home)
  6. Filter is Level (0=No, 1=Yes)
  7. Filter Appears Clean (0=No, 1=Yes)
  8. Lid in Place (0=No, 1=Yes)
  9. Sand Level is More Than 2 inches (0=No, 1=Yes)
  10. Leaks in Housing (0=No, 1=Yes)
  11. Flow Rate (ml/min)
  12. Water Source Flow (0=Stagnant, 1=Flowing)
  13. Raw E. Coli Count (per 100 ml-without filter)
  14. First E. Coli Count (per 100 ml-this is water that has been filtered and sitting at the bottom of the filter from the day before)
  15. Second E. Coli Count (per 100 ml-this is water that was poured in that day and filtered through)
  16. Separate Storage Containers (0=No, 1=Yes)
  17. Type of Containers (1=Wide, 2=Narrow, 3=Both)
  18. Containers Covered (1=None, 2=Some, 3=All)
  19. Containers Clean (0=No, 1=Yes)
  20. Methods to Transfer Water (0=Pour, 1=Dip)
  21. All Drinking Water Produced By Filter (0=No, 1=Yes)
  22. Taste (1=Worse, 2=Same, 3=Better)
  23. Smell (1=Worse, 2=Same, 3=Better)
  24. Appearance (1=Worse, 2=Same, 3=Better)
  25. Reasons Family Like Filter
  26. Change in Health (1=No Change, 2=Better, 3=Decreased malaria, 4=Decreased or no cases of stomach pains, 5=Decreased or no cases of diarrhea, 6=Decreased fever, 7=Decreased malaria/decreased vomiting, 8=Decreased fever/decreased or no cases of stomach pains, 9=Decreased or no cases of diarrhea/decreased or no cases of stomach pains, 10=Decreased malaria/decreased or no cases of stomach pains, 11=Decreased or no cases of stomach pains/decreased malaria/decreased fever)
  27. Time Taken to Reach Water Source (minutes)
