New efforts to reverse centuries of abuse
The 1970s brought reform, such as the Great Lakes Water Quality Agreement that sought to restore the lakes’ “chemical, physical and biological integrity”. But problems remain. Sewage systems continue to overflow, forcing many beaches to close. Levels of some toxins in fish have declined, but others pose new risks. Atlantic freighters still bring in foreign species—there are now 185. Regulations are tangled. In 2007 a refinery in Indiana received a permit to increase discharges into Lake Michigan. Only public uproar prevented it.
