The Environmental Protection Authority (EPA) estimates that $35 million is required to restore the polluted Birim River, which has been severely affected by illegal mining. CEO Nana Ama Brown Klutse disclosed this on February 24, 2026, during a pilot project using ionic nano copper technology at Kyebi-Adukrom in the Eastern Region.

The pilot has shown promising results, but extending the intervention across the 175-kilometer river requires significant funding. It costs approximately $200,000 to treat one kilometer of river, leading to the total cost estimate of $35 million. The degradation of the Birim River has impacted water quality and access for local communities, necessitating ongoing financial support for restoration efforts.
