Chart: Earthquakes in Heart of Texas Oil Country Spur Water Crackdown
(Bloomberg) — Texas is considering new restrictions on how shale explorers dispose of wastewater from oil drilling as earthquakes rattle the largest oil-producing American state.
The new rules would target how much and at what pressure briny water that emerges from oil wells is injected back into the ground, Jared Craighead, chief of staff for the Texas Railroad Commission, … [more…]

The U.S. groundwater supply is smaller than originally thought, according to a new research study that includes a University of Arizona hydrologist.
The study provides important insights into the depths of underground fresh and brackish water in some of the most prominent sedimentary basins across the U.S.
The research by scientists from the University of Saskatchewan, the UA and … [more…]

Michigan businesses are discharging high levels of PFAS that move into the state’s waterways on a daily basis.
An MLive investigation found that manufacturing sources are sending one version of the "forever chemicals" at up to 20,000 times the allowed amount into wastewater systems that discharge it into the state’s lakes, rivers and, ultimately, threatening drinking water supplies for millions of people.
That comes … [more…]
Fecal contamination of urban and peri-urban water bodies is a major health issue in most low- and middle-income countries, where population growth exceeds the rate of development of wastewater or fecal sludge collection and treatment infrastructure. While the expansion of sewer systems and treatment capacity remain a high priority for municipal authorities, there are opportunities for applying low-cost, small-scale on-farm options for safe recovery of wastewater and fecal sludge for … [more…]

Elevated concentrations of strontium, an element associated with oil and gas wastewaters, have accumulated in the shells of freshwater mussels downstream from fracking wastewater disposal sites, according to researchers from Penn State and Union College.
"Freshwater mussels filter water and when they grow a hard shell, the shell material records some of … [more…]
