Developing Bioaugmentation Cultures for Chloroethene Remediation in Low pH Aquifers
One of the major limitations for bioremediation of chlorinated ethenes in aquifers with a pH of approximately 6 and below is the perceived need to adjust the pH to the circumneutral range. This is based on numerous studies with Dehalococcoides and mixed cultures containing Dehalococcoides that indicate a steep reduction or cessation in cDCE and VC reduction to ethene at pH levels below 6. ...

Contract award for East London scheme
HBR have been awarded a contract to carryout groundwater remediation within a busy area of East London. The works will comprise of the installation of 40 deep vertical wells and two horizontal wells positioned within the River Terrace Gravels. The operations are designed to reduce the ammonium from the minor aquifer over a period of 1 to 5 ...

Study: A third of global groundwater basins are overstressed
Satellite data show people are overdrawing water from some of the world's largest groundwater basins. Researchers from the University of California, Irvine say it's unclear how much water is left in the most overburdened aquifers. The problem is expected to worsen with climate change and population growth. Using measurements taken by NASA's twin Grace satellites, scientists found the most ...

UNESCO publishes first world map of underground transboundary aquifers
UNESCO is publishing the first-ever world map of shared aquifers to coincide with the submission to the General Assembly of the United Nations on 27 October of a draft Convention on Transboundary Aquifers. Almost 96% of the planet’s freshwater resources are to be found in underground aquifers, most of which straddle national boundaries. Despite its strategic importance, no global inventory of ...

EPA Designates Mahomet Aquifer as `Sole Source` of Drinking Water in East-Central Illinois
The U.S. Environmental Protection Agency today announced a decision to designate a portion of the Mahomet Aquifer system as a sole source aquifer. More than half of the population in east-central Illinois relies on the Mahomet Aquifer system as a source of drinking water. The Safe Drinking Water Act gives EPA authority to designate all or part of an aquifer as a "sole source" if contamination of ...

Our World’s Water is Diminishing, But How Fast?
The University of California, Irvine (UCI) recently released two studies (here and here) using data from NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites showing that the earth’s biggest groundwater basins are being depleted at troubling rates. The GRACE satellites observed the 37 largest aquifers on the planet by measuring their gravitational pull over the course of ...

U.S. EPA Seeks Public Comment on Mahomet Aquifer Designation
The U.S. Environmental Protection Agency today proposed approval of a petition to designate a portion of the Mahomet Aquifer system in east-central Illinois as a sole source aquifer. EPA’s public comment period on the proposed designation begins March 13 and closes June 12, 2014. The Safe Drinking Water Act gives EPA authority to designate an aquifer as a sole or principal source of ...

New study raises question: What don’t we know about water scarcity?
A new study from the United States Geological Survey (USGS) reveals troubling news: The aquifers that millions of Americans rely on for freshwater are being depleted at an accelerating rate. In fact, aquifer depletion in the years between 2004 and 2008 was nearly triple the historical average. Population growth and increasing demand—in particular for irrigating crops—are straining ...

October Tech Tip: Metals Sorption and pH
At the ambient pH of most aquifers many dissolved metals (Ag, Ba, Cd, Cr, Cu, Fe, Li, Mn, Ni, Pb, Zn) are present as positively charged ions (cations). Transport of these dissolved cations is often controlled by sorption to negatively charged surfaces including sediment iron oxides (e.g., goethite, ferrihydrite, and hematite). At low pH, iron oxides take on a positive charge and sorption of ...

Abu Dhabi looks into stormwater aquifer recharge
The Abu Dhabi City Municipality is investigating the possibility of using stormwater runoff to inject water into coastal aquifers, while at the same time countering the risks of flooding in the city. The municipality is in talks with the Environment Agency – Abu Dhabi (EAD) over the issue, with the city’s drainage collection network set for major investment and expansion this year. ...

Freshwater Aquifer Found off Hawaiian Coast
In areas beset by water scarcity, undersea aquifers - both fresh and brackish - may provide a reliable source of drinking water The bottom of the ocean is not typically where you’d look for new drinking water sources, but recent research is focusing attention in this unlikely direction. In 2019, scientists discovered an extensive aquifer off the Eastern coast of the United States. Now, ...
