Hirose, M; Yamaguchi, A

To root out Minamata disease, which is representative of pollution-caused diseases, a large-scale sediment disposal work was conducted with special care to prevent the secondary pollution due to the work. The basic approach for disposal work consisted mainly of two kinds of ideas. One was to install boundary nets to prevent the mixing of contaminated fish in the Minamata Bay area and noncontaminated fish outside the Bay. The other was to dredge mercury contaminated sediment without disturbance and to confine it in the reclamation area, enclosed by highly watertight revetment. This work was commenced in 1977 and is going to be successfully completed in March of this year with the disposal of roughly 1.5 million cubic meters of sediment over a 2 million-square meter area.
