The Environmental Protection Authority (EPA) has initiated a pilot water cleansing project using ionic nano-copper technology on the Birim River in Adiukrom to address pollution from illegal mining. Concerns have been raised by Professor Paul Poku Sampene Ossei, a Forensic Pathologist, who asserts that while nano-copper is effective against microorganisms, it does not remove heavy metals, which are a significant concern in polluted rivers.

He warns that excessive copper accumulation can lead to oxidative stress, damaging DNA and vital organs. The EPA estimates the project will cost approximately $200,000 per kilometer of river.
