Shinkawa river is a small river, about 3 km long, and flows through Tsuchiura city into Kasumigaura lake of Ibaragi prefecture. I live in Tsuchiura city, close to Shinkawa river, which is polluted, abundant of blue-green algae throwing off fowl odor. Fishes and insects were hardly be seen. Ecology almost collapsed in and around the river.
It was confirmed that "T.S Minetase" activated ecology system of the river and helped improve polluted water.
Right upper picture was taken on October 27, one day before termination of the trial period. Color of the water and smelling of the environment was quite different from 100 days ago. Number of fishermen alongside the river also increased.
Following is a summary of 100 days observation record. Ecology system has recovered its health, which in turn, helped the river regain self-purification capacity.
