Abstract<br />
Groundwater <strong>of</strong> the town <strong>of</strong> Abidjan is collected by many private traditional wells.<br />
This study use hydrochimical, isotopic and statistical methods whose, classification in<br />
typical <strong>of</strong> water and multivariable analysis. The physicochemical analyses carried out on<br />
this water show that they are acid. The average temperature <strong>of</strong> water is close to the ambient<br />
temperature (25°C) <strong>of</strong> the city. Groundwaters are strongly mineral bearing. They are<br />
chlorinated sodic (76%) and bicarbonated sodic (26%). The contents <strong>of</strong> certain chemical<br />
elements in particular the nitrates and lead present values excessive higher than the<br />
standard <strong>of</strong> potability defined by the organization <strong>of</strong> the health (WHO) <strong>of</strong> 50 mg/L and 0,1<br />
mg/L what thus endangers pubic health which consumes them. The groundwaters collected<br />
<strong>of</strong> wells in the town <strong>of</strong> Abidjan are polluted. The principals components analyse shows that<br />
this pollution is <strong>of</strong> anthropic origin. It is the consequence <strong>of</strong> the domestic, industrial and or<br />
artisanal activities carried out in the town <strong>of</strong> Abidjan. The contents <strong>of</strong> stable isotopes <strong>of</strong> the<br />
environment indicate that this tablecloth is reloaded starting from the infiltration <strong>of</strong><br />
rainwater.
