2022 Cat A - Chromatic riparian decontamination
The site is close to River Tawe to the north where floods occurred relatively frequently, and the two communities near the site, Caehopkin, and Ystradgynlais, were most affected. More importantly, after a long period of mining, the soil is heavily polluted by heavy metals. In particular, the site has abundant rainfall. The soil pollutants may penetrate into groundwater through the soil and then slowly flow into river channels, affecting the water source on which people depend for survival. And with global warming, heavy rains and flooding will become more intense, and water pollution from mining will become more frequent. The area is devoid of life due to mining, but outside the mining area is in good ecology. In addition, there are two nature reserves in the northeast and northwest corner of the site, as well as abundant species along the river. In the context of these situations, my project will build a biological hydrological network to reorganize the connection between water and biology at the site. I will use an Acid Mine Drainage Remediation system to realign the flow direction of the site to form a continuous water network, combined with topography and water purification plants, to purify and eventually flow into the mine crater. After the long-term function of my probiotic agent(water) and rewilding, the species in the surrounding environment start to spread. There will also be a rewilding corridor for species, which helps restore the soil quality of the riparian zone. Through the harmonious combination of hydrological network and creatures, rewilding is finally achieved.
