Good job bringing this to light. People won't realise how huge the problem is and municipalities are woefully ill equipped to...
Agreed; mining can never be sustainable, but then how do you get the metals to make all the things you need in the course of...
Very good piece.
An electrical technique developed at the Pacific Northwest National Laboratory, USA, would help clean contaminated land. In this process, electric current is employed to heat the soil that leads to evaporating the moisture. Thus, volatile contaminants are removed from soil particles. Contaminated steam is then collected above ground and treated. Researchers are now developing a method to destroy non-volatile contaminants. They would use high voltages to destroy organic contaminants such as grease, pesticides and oil.
