Michigan Water Pollution Reversal Requires Global Solution
Since Congress approved the Clean Water Act in 1972, most of Michigan’s lakes and rivers have seen improved water quality, but mercury and toxic PCB pollution is still a problem that needs to be resolved.
The problem however, cannot be solved without cutting global emissions. The reason, 75% of the mercury and 55% of the PCBs that fall into Michigan waters come from outside the state.
Reducing PCBs and mercury in Michigan fish to safe concentrations would require global PCB emissions by 94% and global mercury emissions by 82%, getting there could take over 50 years.
