Background

ESW Stanford is currently working to organize information on varous testing techniques that are often needed by our collaborators in the field.
Challenges arise daily while working in rural, remote locations of the world. Supplies of clean water and electricity may be inconsistent or nonexistent. Water quality testing critical to determining the effectiveness of sanitary interventions becomes a daunting task under such conditions. Many sophisticated techniques used in conventional laboratories become too expensive, too impractical, or too difficult to use in developing nations.
We are working to compile a survey of existing technologies that are designed for remote, inaccessible locations. On the following pages one will find information on some the techniques we have researched.

Format

All of the following pages include:

• Topic Background: Prevalence, Symptoms, Worldwide Health Significance, Indicators, Importance of Testing
• Testing Matrix Summary:

Summary of Testing Methods
