Sewers at Capacity, Pollution Spills Into Waterways - NYTimes.com
One goal of the Clean Water Act of 1972 was to upgrade the nation’s sewer systems, many of them built more than a century ago, to handle growing populations and increasing runoff of rainwater and waste. During the 1970s and 1980s, Congress distributed more than $60 billion to cities to make sure that what goes into toilets, industrial drains and street grates would not endanger human health.
But despite those upgrades, many sewer systems are still frequently overwhelmed, according to a New York Times analysis of environmental data. As a result, sewage is spilling into waterways.
In the last three years alone, more than 9,400 of the nation’s 25,000 sewage systems — including those in major cities — have reported violating the law by dumping untreated or partly treated human waste, chemicals and other hazardous materials into rivers and lakes and elsewhere, according to data from state environmental agencies and the Environmental Protection Agency.
But fewer than one in five sewage systems that broke the law were ever fined or otherwise sanctioned by state or federal regulators, the Times analysis shows.
