THE CHALLENGE OF WATER IN SANITARY CONDITIONS IN CANAAN

The Canaan district, a shantytown built in an area where drought rages, not only faces difficult access to water, but also the few water resources available are non-potable. Through Unicef/WHO, drinking water is defined as water whose microbial, chemical and physical characteristics comply with WHO guidelines or national drinking water quality standards. Following the earthquake of January 12, 2010, the already precarious water supply has deteriorated. DINEPA, the public institution responsible for implementing the State's public policy in the drinking water and sanitation sector, is struggling to fulfil its role.

The groundwater of the plaine du cul de sac is the largest source of underground water used by the population of the metropolitan area to satisfy their water needs. In Port-au-Prince, in addition to oocysts of cryptosporidium parvum, a parasitic protozoan, the risk of faecal contamination of the environment is very high. Clusters of faecal coliforms have been found in the water sources used to supply the population, and around 700 faecal coliforms per 100 ml have been detected in the groundwater of the cul de sac plains.

The aim of this study will therefore be to analyze the population's vulnerability to water-borne diseases.
