Study finds high sodium bicarbonate concentrations in water from coal-bed natural gas production harms aquatic life; water treatment can mitigate effects

Green Car Congress

Produced water from coal-bed natural gas (CBNG) production may contain sodium bicarbonate (NaHCO 3 ) at concentrations that can harm aquatic life, according to a new study by the US Geological Survey; Montana Fish, Wildlife and Parks; the Bureau of Land Management and the US Environmental Protection Agency.

The presence of monovalent ions, such as sodium and potassium, is not a significant issue in the conventional precipitation method since their salts are highly soluble. ppm) and an abundance of interfering ions (i.e., doi: 10.1039/D1EE00354B.

Ionic liquid-enhanced solvent extraction for oil sands bitumen shows high recovery rates, less water use and no tailing water

Green Car Congress

Canadian oil sands are a complex mixture of sand, clays, water, and bitumen. For surface mining oil sands production, a hot water extraction process (HWEP) has been widely applied. In this process, hot water and processing aids are mixed with oil sands to liberate bitumen from the minerals by shearing the oil sand particles.

UMD-led study: road salts and other human sources are threatening world’s freshwater supplies

Green Car Congress

But a new study led by Sujay Kaushal of the University of Maryland warns that introducing salt into the environment—whether it's for de-icing roads, fertilizing farmland or other purposes—releases toxic chemical cocktails that create a serious and growing global threat to our freshwater supply and human health.

Researchers discover new way seawater could corrode nuclear fuel

Green Car Congress

Uranium in nuclear fuel rods is in a chemical form that is “pretty insoluble” in water, said Professor Alexandra Navrotsky, UC Davis, corresponding author on the paper, unless the uranium is oxidized to uranium-VI—a process that can be facilitated when radiation converts water into peroxide, a powerful oxidizing agent.
