As Chicago suburbs expand, their residents are looking increasingly to Lake Michigan for drinking water, according to Medill Reports Chicago . The lake, which has already been substantially tapped, may not be able to provide enough.
Unless conservation efforts are increased, experts say low lake levels and legal restrictions will leave many suburbs short of the water they need. Many of the communities are already extracting unsustainable levels of water from wells nearby.
A few Chicago suburbs have even seen elevated radium levels from over pumping wells, which is sometimes found in groundwater. With no regulation of groundwater use in Illinois, experts say the suburban sources will eventually run dry.Read More
Ocean acidification: University of Washington's giant plastic bags help control research conditions
With oceans becoming more acidic worldwide, scientists are getting creative in designing experiments to study them. For example, one group at the University of Washington is using giant plastic bags to study ocean acidification.
Each bag holds about 3,000 liters of seawater and sits in a cylinder-like cage for stability. The group at UW, made up of professors and students, is controlling carbon dioxide levels in the bags over a nearly three-week period, during which they are looking at the effects of increased acidity on organisms living near the San Juan Islands.
“These mesocosms are a way to do a traditional experiment you might do in a lab or classroom,” said Jim Murray, professor of oceanography at the University of Washington.Read More
National Oceanic and Atmospheric Administration scientists detected signs of ocean acidification in the waters that hold the vulnerable and valuable fisheries of the North Pacific off the coast of Alaska, but they only had a snapshot of the action.
“We know that in this place were important commercial and subsistence fisheries that could be at risk from ocean acidification,” said Jeremy Mathis, a NOAA Pacific Marine Environmental Laboratory researcher and professor at the University of Alaska Fairbanks.
To understand how ocean acidification affects the North Pacific, NOAA scientists created a mooring network that collects constant in situ data on parameters contributing to acidification. They hope it will reveal seasonal trends and patterns left out by their snapshots.Read More
