Simple colorimetric test strips can make a profound impression. In 1999, Lifewater volunteers were working in a community in Ghana. During the training workshop, the local well was tested. It was found to contain elevated levels of nitrate and nitrite — clearly related to a latrine located right beside the well.
Facility leaders were shown the dark colours on the test strips. They asked what it meant and were told that the latrine was contaminating the well and that an infant drinking water from it could get sick to the point of death.
The workshop then resumed but communication was difficult due to loud, rhythmic pounding. During a break the volunteers went outside and found the source of the noise. The latrine was being torn down, even while the workshop was still in session! Education can mobilize people and bring about needed change!
