Our world is so gross right now. Via Inhabitat:
The EPA has declared that an astounding 55 percent of rivers and streams in the country are in “poor condition for aquatic life.”
The results of their first comprehensive survey of waterway health reveal shrinking vegetation cover, high levels of phosphorous and nitrogen, and pollution from mercury and bacteria—none of which are all that great for human health either. Additionally, as the EPA emphasizes, the polluted, unhealthy waterways include vital sources of drinking water.
So where are these contaminants coming from? Phosphorous and nitrogen, both key ingredients in fertilizer, have long been recognized as a problem in US water health. 40 percent of waterways surveyed had high levels of phosophorous, while high levels of nitrogen were found in 27 percent of waterways.
Over 13,144 miles of waterways featured levels of mercury that similarly exceed safe levels for human health, making it ill-advised to consume fish from those areas.
