The Clean Water Act (CWA) was passed in 1972, leading to the regulations for waterways we have today. In 1969 a river in Ohio started to burn, believed to be set off by a spark from a railcar. This was the thirteenth time a river in Ohio had caught fire due to high levels of pollutants. River fires were so common at that time, Time Magazine used a stock photo from a different river fire. While the CWA was passed with support from both parties, the recent rollbacks could be endangering wildlife and waterways.
