Up the river in Borneo

Mercury, used in the mining process, also taints the water, although we see local boats fishing. I struggle to understand how this “illegal” mine is so well known- it is referenced in signage at Camp Leakey, most of which appears to be at least a decade old. It’s in the descriptions of the area online. Why isn’t anything done about it? Indonesia has systemic issues with corruption, although it has made tremendous progress to improve the record under the current president, “SBY”- Susilo Bambang Yudhoyono, an acknowledged corruption buster at high levels. It is simply pervasive.
