RATIONAL EXPRESSIONS

POLLUTION IN CHICAGO Recently, the Chicago River was added to the EPA’s list of “America’s Most Endangered Rivers”, due to the 1.2 billion gallons of partially treated human and industrial waste dumped into the river every day. The cleanup would require up to $72 million in new germ-killing equipment at two sewage treatment plans and $355 million to complete the Deep Tunnel project, a labyrinth of sewer pipes and reservoirs designed to store waste and storm runoff until it can be treated. Is this worth it?
