Abstract:
Dassa-Zoumes population has no spillway of human excreta and domestic wastewater.
Management of excreta and wastewater pose real problems on the environment and human
health. The objective of this work is to study the consequences of poor management of human
excreta and domestic wastewater on the environment and human health. Documentation, direct
interview, interviews and observations of water samples, were the methodological steps for data
collection. Analysis of linear regression tests helped in assessing the degree of connection
between fecal and hygiene and sanitation hydro diseases. This was complemented by socio -
economic investigations and the application of the model PEIR (Pressure-State - ImpactResponse) to better analyze the consequences of poor management of human excreta and
domestic wastewater on the environment and health. The analysis shows that in the commune of
Dassa-Zoume, good numbers of fecal hydro diseases stem from poor management of excreta and
wastewater. The lack of sanitation pollutes water wells and surface water. The physico- chemical
and bacteriological analyzes of well water and river are the main sources of drinking water
revealed the presence of high levels of fecal coliform bacteria that are in the order of 7777.5
CFU / ml for well water , 21946.15 CFU / ml for water tank 71,385.71 CFU / ml for river waters
and E . Coli 2773 UFC/100ml for wells, tanks for UFC/100ml 6363.73 and 7751.52 UFC/100ml
for rivers. These water sources are polluted and unfit for consumption. The use of this water
causes many cases of fecal the most recurrent in common are diarrheal diseases, gastrointestinal
infections hydro diseases. In 2011 the town had more than 133 cases of cholera and many cases
of gastro- intestinal infections. He is urgent to improve access to safe drinking water to all the
people of the town and to provide these populations works excreta disposal and wastewater to
limit the consequences of defecation to outdoors on the environment and human health. |
