Captured at a Trianon, Haiti in February 2013, three years after a devastating earthquake, this image depicted representatives of the National Directorate for Drinking Water and Sanitation (DINEPA), who were in the process of performing tests on water samples, in order to determine their chlorine concentration. Here, one tech was adding the required DPD colorimetric reagent (N,N-diethyl-p-phenylenediamine) to the sample, and will look for the appropriate color change in the presence of chlorine. With Centers for Disease Control and Prevention (CDC) support, 54 of the 270 Drinking Water and Sanitation Technicians, or TEPAC (Techniciens en Eau Potable et en Assainissement pour les Communes) across Haiti, work for, and are equipped with motorcycles and testing equipment, and salaried through DINEPA.
