Challenge 3 safe water opt

  1. 1. Safe Water Optimization Tool for Humanitarian Response Syed Imran Ali Ph.D., Dahdaleh Institute for Global Health Research, York University Jean-Francois Fesselet, Public Health Department, MSF-OCA Matt Arnold, MSF-OCA/DIGHR Emergency Data Science: Taking Advantage of the Data Flood | December 4th, 2018
  2. 2. • Waterborne diseases  leading threats • Safe water is essential for public health Core Challenge
  3. 3. • Chlorination is the main method for water treatment  Cheap, easy to use, offers residual protection • Current guidance not based on any field evidence  Often fails to ensure water is safe Core Challenge
  4. 4. • Hep E, South Sudan, 2012-13 • CDC: 40-60% households with no detectable chlorine1 • U of Barcelona: faecal viruses in stored water2 • Post-distribution contamination  waterborne diseases in camps in Uganda, Malawi, Kenya, Sudan3-8 Field Experience (1) CDC.

  5. 5. • Emergency guidelines not based on evidence from emergency settings Came from WHO GDWQ for cities • Not suitable for refugee camps • What’s important is water safety in the household! Core Problem
  6. 6. • Evidence-based guidance for water treatment in emergencies • UC Berkeley, UNHCR, MSF, HIF • 2014-2016: South Sudan, Jordan, Rwanda, Tanzania Previous Research
  7. 7. New Evidence-based Guidance
  8. 8. What would be ideal is to have a unique water treatment guideline for every site The Next Opportunity
  9. 9. …takes routine monitoring data and applies data analytics to generate customized water chlorination guidance for any field site that ensures water is safe to drink. Safe Water Optimization Tool
