Environmental impact assessment from marble exploitation on surface and underground water in SAKALALINAMADAGASCAR

The determination of the impacts of marble exploitation on the surface and underground water at SAKALALINA-MADAGASCAR was determined by assessing the physico-chemical properties of the water samples obtained from SAKALALINA and its environs. The concentration of Fe, Mn, Cu, Zn, Pb, Cd, Hg, As and selected major ions in water samples were analyzed in the laboratory to assess their role in the contamination of both surface and ground water. The water in this Study area is mainly used for drinking and industrial purposes followed by agriculture to some extent.
