The Armed Forces of Ukraine blew up the Ternovskaya dam of the Kurakhovo Reservoir, strana.ua said in its Telegram channel. Russian military pages reported the same.  "Apparently, the AFU decided to blow up the facility in order to slow down the advance of the Russian army,” authors of War Correspondents of the Russian Spring Telegram channel said.

Ukraine showed a video of the explosion of the Kurakhove water reservoir dam in the Donetsk People's Republic (DPR). The video that was published by Ukraine's TSN TV military correspondent Yulia Kiriyenko shows the moment and aftermath of the explosion on the reservoir near the village of Starye Terny. The dam itself, the road passing through it, and a technical structure located nearby were partially damaged in the explosion. At the same time, the video does not show a possible artillery or air strike on the dam. This confirms that the Russian army was not involved in the destruction of the dam.

The differentially pumped rare-gas filter at the end of the VUV beamline of the Swiss Light Source has been adapted to house a windowless absorption cell for gases. Absorption spectra can be recorded from 7 eV to up to 21 eV photon energies routinely, as shown by a new water and nitrous oxide absorption spectrum. By and large, the spectra agree with previously published ones both in terms of resonance energies and absorption cross sections, but that of N2O exhibits a small shift in the { ilde{f D}} band and tentative fine structures that have not yet been fully described. This setup will facilitate the measurement of absorption spectra in the VUV above the absorption edge of LiF and MgF2 windows. It will also allow us to carry out condensed-phase measurements on thin liquid sheets and solid films. Further development options are discussed, including the recording of temperature-dependent absorption spectra, a stationary gas cell for calibration measurements, and the improvement of the photon energy resolution.

The absence of solvent molecules in high-resolution protein crystal structure models deposited in the Protein Data Bank (PDB) contradicts the fact that, for proteins crystallized from aqueous media, water molecules are always expected to bind to the protein surface, as well as to some sites in the protein interior. An analysis of the contents of the PDB indicated that the expected ratio of the number of water molecules to the number of amino-acid residues exceeds 1.5 in atomic resolution structures, decreasing to 0.25 at around 2.5 Å resolution. Nevertheless, almost 800 protein crystal structures determined at a resolution of 2.5 Å or higher are found in the current release of the PDB without any water molecules, whereas some other depositions have unusually low or high occupancies of modeled solvent. Detailed analysis of these depositions revealed that the lack of solvent molecules might be an indication of problems with either the diffraction data, the refinement protocol, the deposition process or a combination of these factors. It is postulated that problems with solvent structure should be flagged by the PDB and addressed by the depositors.

The synthetic availability of mol­ecular water oxidation catalysts containing high-valent ions of 3d metals in the active site is a prerequisite to enabling photo- and electrochemical water splitting on a large scale. Herein, the synthesis and crystal structure of di­ammonium {μ-1,3,4,7,8,10,12,13,16,17,19,22-dodeca­aza­tetra­cyclo­[8.8.4.13,17.18,12]tetra­cosane-5,6,14,15,20,21-hexa­onato}ferrate(IV) acetic acid tris­olvate, (NH4)2[FeIV(C12H12N12O6)]·3CH3COOH or (NH4)2[FeIV(L–6H)]·3CH3COOH is reported. The FeIV ion is encapsulated by the macropolycyclic ligand, which can be described as a dodeca-aza-quadricyclic cage with two capping tri­aza­cyclo­hexane fragments making three five- and six six-membered alternating chelate rings with the central FeIV ion. The local coord­ination environment of FeIV is formed by six deprotonated hydrazide nitro­gen atoms, which stabilize the unusual oxidation state. The FeIV ion lies on a twofold rotation axis (multiplicity 4, Wyckoff letter e) of the space group C2/c. Its coordination geometry is inter­mediate between a trigonal prism (distortion angle φ = 0°) and an anti­prism (φ = 60°) with φ = 31.1°. The Fe—N bond lengths lie in the range 1.9376 (13)–1.9617 (13) Å, as expected for tetra­valent iron. Structure analysis revealed that three acetic acid mol­ecules additionally co-crystallize per one iron(IV) complex, and one of them is positionally disordered over four positions. In the crystal structure, the ammonium cations, complex dianions and acetic acid mol­ecules are inter­connected by an intricate system of hydrogen bonds, mainly via the oxamide oxygen atoms acting as acceptors.

In the structure of the title compound, C22H22N4O4·C3H7NO·H2O, the entire tricyclic system is approximately planar except for the carbon atom bearing the two methyl groups; the meth­oxy­phenyl ring is approximately perpendicular to the tricycle. All seven potential hydrogen-bond donors take part in classical hydrogen bonds. The main mol­ecule and the DMF combine to form broad ribbons parallel to the a axis and roughly parallel to the ab plane; the water mol­ecules connect the residues in the third dimension.

For the last month, Frank Galaviz has wondered when running water will return to his town.

The 77-year-old resident of Teviston — a small rural community in Central California — has been forced to depend on stored and bottled water after the pump in the town's only functioning well broke down in early June. Since then, residents have had to travel to neighboring towns to shower or depend on the town's water storage tanks for their daily needs.

Temperatures continue to reach into triple digits as a brutal heat wave sweeps across the West Coast. The ongoing drought only exacerbates the problem, Galaviz says.

"[My wife and I] have lived through many challenges," he says. "We both have survived cancer, but we will not be able to survive without water. This is a problem that is not going away."

Teviston sits between the cities of Fresno and Bakersfield in the San Joaquin Valley and is home to mostly Latino farmworkers. Normal days in town are usually slow-paced and idyllic, Galaviz says, with many residents commuting to the nearby towns and cities on business. Now, they leave to find more water.

This is not the first time Galaviz or his neighbors have struggled with a broken well. He says two other wells had broken down in previous years and had not been repaired. A new, more modern well is in the works, but Galaviz estimates its completion is still a few years off.

The community continues waiting for repair parts to arrive in hopes it will fix the current well's pump, he added, a process that could take a few weeks.

"It is not normal to not be able to flush toilets," he says. "It's not normal to not be able to take a shower."

Residents have managed to come up with a temporary fix, using their water storage tanks to offer relief.

"We were able to get some of the water pressure back," Galaviz said. "We put a submersible pump into one of our old wells and we're forcing water from the storage tanks through that system. But it's not a permanent fix."

Rural Latino communities in California have been particularly vulnerable to drought conditions, according to a report from the state Legislative Analyst's Office.

"Having no water equals bad health," state Sen. Melissa Hurtado, who serves California's 14th District, tells Weekend Edition. Hurtado says her bill, SB 559, would allot $785 million to fund and repair water supply infrastructure. One of the waterways posed for fixing is the Friant-Kern canal, which supplies Teviston and the towns around it. Over the years, the canal has become subject to subsidence — a condition that has caused some parts of the canal to sink and means it can't deliver as much water.

"SB 559 would help fix the canal so that the basin and the communities that rely on water here would be able to have more access to it," Hurtado says.

Galaviz has spent the last few weeks knocking on doors to check in on neighbors and trying to organize help.

"I have a neighbor whose daughter has medical problems. She needs drinking water, pure water," he says. "It hurts to see people suffering."

Radon in household water supplies increases peoples overall exposure to the gas, but waterborne radon poses few risks to human health, says a new report by a committee of the National Research Council.

The federal government should not increase the maximum level of copper allowed in drinking water, because higher levels could lead to liver poisoning in infants and children with certain genetic disorders.

The vast majority of healthy people adequately meet their daily hydration needs by letting thirst be their guide, says the newest report on nutrient recommendations from the Institute of Medicine of the National Academies.

The U.S. Environmental Protection Agencys standard for the maximum amount of fluoride allowed in drinking water -- 4 milligrams of fluoride per liter of water -- does not protect against adverse health effects.

Evidence exists that people who lived or worked at Camp Lejeune Marine Base in North Carolina between the 1950s and 1985 were exposed to the industrial solvents tricholorethylene (TCE) or perchloroethylene (PCE) in their water supply, but strong scientific evidence is not available to determine whether health problems among those exposed are due to the contaminants, says a new report from the National Research Council.

The numerous technical and operational breakdowns that contributed to the Deepwater Horizon oil rig explosion and spill from the Macondo well in the Gulf of Mexico suggest the lack of a suitable approach for managing the inherent risks.

Hydraulic fracturing has a low risk for inducing earthquakes that can be felt by people, but underground injection of wastewater produced by hydraulic fracturing and other energy technologies has a higher risk of causing such earthquakes, says a new report from the National Research Council.

Over the next several decades as the global population grows, society will be faced with pressing challenges such as providing reliable supplies of food and water, diminishing climate change and adapting to its impacts, and building healthy, resilient cities.

A new report from the National Academies of Sciences, Engineering, and Medicine offers guidance to the U.S. Environmental Protection Agency to inform the next revision of a permit program that requires industries to manage stormwater to minimize discharges of pollutants to the environment.

The supercritical water oxidation (SCWO) system is a secondary waste processing reactor of the Blue Grass Chemical Agent Destruction Pilot Plant (BGCAPP). It is perhaps second in importance behind the agent neutralization reactors, which perform base hydrolysis of chemical warfare agents stored at the Blue Grass Army Depot.

After several months sitting empty and quiet, commercial districts are coming back to life as businesses and offices are being given permission to reopen. When the lights come on and doors are unlocked, will the water that comes out of the tap be safe?

A review of the New York City Watershed Protection Program, released today by the National Academies of Sciences, Engineering, and Medicine, says the program has been largely successful in maintaining and enhancing water quality for New York City’s drinking water since its inception in 1997.

In many cities, shrinking populations and aging infrastructure mean increasingly unaffordable water

When shellfish farmers are deciding where to grow clams and oysters, they’re often acting on outdated water quality data — which can interrupt harvesting and cost them income. Gulf Research Program Fellow Natalie Nelson is working to predict water quality trends, so shellfish farmers can make better informed decisions.

Throughout the COVID-19 pandemic, wastewater surveillance has provided advance indications of community-level outbreaks, sometimes weeks before other indicators. A new report says that wastewater surveillance is worthy of investment and outlines a vision for the future of a national system.

Most of the offshore oil and gas industry operating in the Gulf of Mexico has improved its management of systemic risk in recent years, according to a new report that also points out where uneven progress and critical gaps remain for industry and regulators to address.
