In The News
Sulfate concentrations continue to decline in Northeast U.S. streams, according to a new analysis of 40-years' worth of water quality data from relatively pristine watersheds across the country. The analysis shows the effectiveness of the Clean Air Act and the value of a unique stream monitoring network that has faced frequent threats of having its budget cut.
The U.S. Geological Survey's Hydrologic Benchmark Network covers stream sites in watersheds that have seen little disturbance from humans through activities like urban development, agriculture or dam building. The HBN launched in 1963 and once had as many as 59 sites, but has since been slimmed down to 37. A USGS gauge measures streamflow at each site and a smaller set of sites are sampled for water chemistry.Read More
It’s an open, dirty secret that the ocean is used as the ultimate sewage solution.
Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up.
“This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.Read More
In 2012, for maybe the first time, Lake Superior got scummy.
Visitors to the Apostle Islands National Lakeshore reported algae washing up on shore around the park.
It was a marked shift for the park, made up of a portion of the Lake Superior lakeshore and nearby islands. The water surrounding the park is cold, clear and typically low in nutrients: a combination unlikely to result in algal blooms.
But, in 2012 and again in 2018 after violent storms, major algal blooms—ones observed over multiple days—washed ashore and clogged the beaches with unsightly, scummy algae.
Not the usual suspects
The algal blooms of Lake Superior are not the algal blooms of warmer, more nutrient-rich lakes like Lake Erie.Read More
