South Carolina District Court reinstates the Clean Water Act WOTUS rule in twenty-six states

Atlean Lake in British Columbia

On August 16, the South Carolina District Court ruled that President Donald Trump’s Executive Order 13778 to suspend the Obama Administration’s Clean Water Rule was in violation of the Administrative Procedure Act. Finalized in 2015, the Clean Water Rule—also called the Waters of the United States or WOTUS rule—clarified the scope of federal water protected under the Clean Water Act. The nationwide halt of the applicability date rule effectively reinstates the WOTUS rule in twenty-six states.

Managing Groundwater Storage

Wednesday, July 18, 2018

Background:
Groundwater is a critically important source of water in the U.S., supplying fresh water for drinking supplies, agricultural irrigation, and streams, rivers, and ecosystems. However, groundwater is becoming increasingly depleted in most aquifers around the country, with impacts including shrinking aquifer storage capacities, land subsidence (and associated impacts like higher flood risk), and declining freshwater resources for communities and ecosystems. To mitigate and reverse the depletion of groundwater storage in local aquifers, many communities are turning to managed aquifer recharge (MAR) and aquifer storage and recovery (ASR). MAR and ASR practices vary depending on local geology, groundwater and recharge water composition, local land use practices, and water use requirements. Implementing MAR and ASR requires careful planning to both maximize groundwater replenishment and protect groundwater supplies from contamination.

IUGS: Resourcing Future Generations Second Open Call for Proposals

IUGS Logo
The International Union of Geological Sciences has posted its second open call for the its global initiative called Resourcing Future Generations (RFG), to bring geoscientists together to address the world's future resource needs head-on. Bids for small top-up grants to take forward discrete pieces of work in support of RFG. Grants will average $3000, but more may be awarded. More information ins available in right sidebar on the linked site.
