ABSTRACT: The municipal Akouedo landfill of the city of Abidjan (Cote d’Ivoire) is composed
of more than 60% of household waste. It lacks a leachate collecting and
treatment device. To highlight the impact of the leachate on the receiving environments,
some sampling campaigns of leachate, groundwater and surface
waters were conducted from June 2013 to January 2014. Analyses of leachate
samples revealed relatively high concentrations of trace metals: Fe (6450 ±
8690 μg/L), Cu (400 ± 272 μg/L), Zn (520 ± 240 μg/L), Cd (113 ± 105 μg/L),
Pb (550 ± 237 μg/L), Ni (312 ± 97 μg/L) and Co (77 ± 56 μg/L). Fe is the most
abundant chemical element. The analysis of groundwater and surface indicates
that the levels of trace metals in these waters are higher than WHO
standards except Zn.
