Memories in the Ground--The Intersection of Technology and Ethics of Regeneration (December 2008)
Japan's soil and groundwater are quietly eroding. Technology has finally emerged to respond to the silence that was once overlooked in the name of industry. From surface removal to in-situ remediation. The jet rinse method, which uses high-pressure water to flush out the water, the Svajnavi method, which uses the power of microorganisms to decompose the water, and sand washing-all have the philosophy of "not moving the site, but following the laws of nature.
On the other hand, there is also the option of containment. Bottom barriers and encircling geobarrier technologies are attempts to stop the spreading shadow at the boundary. Companies measure the risk and offer their technology. Chemical grouting and Kashima Road, for example, have inorganic names, but their activities are rooted in human responsibility and ethics.
The mistakes of the past accumulated in this ground will be rewrapped with the knowledge and sincerity of the future. What we see ahead is not just harmlessness, but a new landscape of symbiosis between society and technology.
