Economic impact of invasives in the Great Lakes
The Great Lakes – our largest global reserve of freshwater – are under attack from invasive species, and a new study provides an estimate of what this will cost us.

The inevitable expansion in renewable energy infrastructure will require keen attention and careful management of restricted water supplies.
Though shale gas extraction with the use of hydraulic fracturing has been underway in the U.S. for about a decade, peer-reviewed literature looking at its impacts has only begun to be published. Some of the articles that were among the first published on the environmental impacts, and remain among the most talked about, are described here.
Previous research on hydraulic fracturing has indicated possible contamination of water wells by methane. A new research article attempts to model potential contamination pathways to aquifers from Marcellus shale gas beds.
Drinking water wells are only 60 to 90 meters below the surface, while the Marcellus Shale is at depths of 1,200 to 2,500 meters. Still, new research suggests that, because of the hydrology of northeastern Pennsylvania, hydraulic fracturing poses a risk to these shallow drinking water resources.
Scientists explore how and what kind of methane makes it into natural gas wells.
A new study calculates the total water usage for shale-gas production in Texas. While the total water usage doesn’t overwhelm state resources currently, the variability in local conditions over time will call for more careful consideration of water resources in the future.
The government is supposed to provide clean drinking water. But, in many cases, they aren’t and consumers are paying for it.
Some populations – often those with the fewest resources and constituting a racial minority – ultimately pay more for basic water and sewer services than others.
Coral reefs are one of the most critically endangered ecosystems on the planet, and untreated human waste is contributing to their decline.
