A large smelter was built in East Helena in USA around 1888. Historically, slag was considered innocuous and in absence of strict regulations, often dumped directly into lakes, streams, and low-lying areas in forests. The scale of heavy metal pollution in environment is as massive as the economic impact of Industrial Revolution. In general, the prominent heavy metals in slag-contaminated sites are lead (Pb), chromium (Cr), zinc (Zn), cadmium (Cd), copper (Cu), mercury (Hg), and nickel (Ni). The restoration project is creating an eight mile trail and park system connecting East Helena to Montana City’s community trails. East Helena is a success story of one of the world’s prominent slag piles receiving significant attention from the authorities. A restoration revolution is required to address the issue of environmental degradation caused due to the Industrial Revolution. The United Nations has declared 2021- 2030 as the UN Decade on Ecosystem Restoration, with one common goal of preventing, halting and reversing the destruction of natural spaces. Together, we need to build a global movement to accelerate remediation and restoration efforts to bring the world back on the track for a sustainable future.
