The new findings were published today in the journal Proceedings of the National Academy of Sciences.Oil and gas development — particularly the introduction of horizontal drilling and high-volume hydraulic fracking — has generated public concern in Colorado over potential groundwater contamination due to the possibility of leakage from oil and gas wells. When present, natural gas can turn drinking water flammable, a safety hazard observed in numerous historical cases.The researchers sifted through over 25 years of publically-available historical information in order to determine the sources and occurrence rate of methane and other gases in groundwater. All of the data were sourced exclusively from open records maintained by the Colorado Oil and Gas Conservation Commission (COGCC), a regulatory division of the state’s Department of Natural Resources.The study was funded entirely by the National Science Foundation’s AirWaterGas Sustainability Research Network, which is based in Boulder, Colorado. “The ability to do this kind of far-reaching impact study using public domain data is key,” said Owen Sherwood, a research associate with the Institute for Arctic and Alpine Research (INSTAAR) at CU Boulder and lead author of the new research. “This study highlights the immense value of a large, continuously updated and publically accessible geochemical database maintained by a regulatory agency.”In data dating back as far as 1988, dissolved methane was discovered in 523 of the 924 water wells sampled, a rate of about 64 percent. However, based on a geochemical analysis, the researchers determined that 95.5 percent of that methane was generated by naturally-occurring microbial processes, a result of proximity to shallow coal seams criss-crossing northeastern Colorado.Aside from the microbial methane, oil and gas wells have been found to leak methane and other natural gases such as propane and butane due to faulty or unsuitably shallow surface casings. Older gas wells built as far back as the 1970s were typically cased to a depth of approximately 300 feet, leaving the state’s deepest water aquifers unprotected from potential gas leaks. Updated regulatory standards have since required that new wells be cased far deeper and a number of older wells are currently being repaired. Between 2001 and 2014 (the last year of complete data), dissolved gas that could be directly linked to deep oil- and gas-bearing formations affected 42 water wells in 32 separate incident cases, a rate of about two cases per year. That rate did not change after the introduction of horizontal drilling and high-volume hydraulic fracturing in the state in 2010. Eleven of those cases could be linked to older, vertical wells drilled before 1993. The remaining 21 cases were either settled privately with the landowner, or remain unresolved due to lack of data.“This study incorporates a tremendous amount of hard data, but also considers individual case narratives so that we can see what happened in each particular instance of natural gas contamination,” said Joseph Ryan, a professor in the Department of Civil, Environmental, and Architectural Engineering at CU Boulder and a co-author of the new study. “It’s important to remember the human impact of this issue across the state.”The new research is believed to be the most comprehensive study to date on the prevalence and sources of groundwater methane in Colorado using only public data. Previous studies have sampled fewer oil and gas sites and/or relied on data provided by industry stakeholders. Published: July 11, 2016 The rate of groundwater contamination due to natural gas leakage from oil and gas wells has remained largely unchanged in northeastern Colorado’s Denver-Julesburg Basin since 2001, according to a new University of Colorado Boulder study based on public records and historical data.The results also suggest that microbially-generated methane, rather than high-volume hydraulic fracturing, is the primary source of dissolved methane present in the area’s groundwater. Old and faulty oil and gas wells contribute a smaller percentage, with the risk of groundwater contamination due to a leak estimated to be between 0.12 percent of all the water wells in the region to 4.5 percent of the water wells that were tested.

The missing informal workers in India’s vaccine story Heartfulness group of organisations launches ‘Healthcare by Heartfulness’ COVID care app #Vocal for LocalCoronaOvenCOVID-19Emmanuel Macron’lockdownLog 9 MaterialsMake In IndiaPrime Minister Narendra ModiSARS-CoV1SSI GroupUltraViolet germicidal irradiationUS FDAUV-C rays Add Comment Read Article News Share Related Posts By EH News Bureau on May 27, 2020 Comments (0) SSI Group has placed orders for few paid samples of CoronaOven; one of these initial samples will be placed at Élysée Palace, i.e. President of France Emmanuel Macron’s official residenceAmidst the enormous socio-economic challenges arising out the COVID-19 pandemic and the subsequent countrywide lockdown, Prime Minister Narendra Modi, in his latest address to the nation, urged commoners and stakeholders across the country to ‘go vocal for local’ in an attempt to strengthen our local businesses. While the Prime Minister’s forward-thinking outlook and vision for the future is laudable, it is imperative to highlight that in order to harness its maximum potential and pave the way for a ‘self-reliant India’ in the coming years, the ‘vocal for local’ initiative must not restrict itself only towards reviving the older traditions and / or small enterprises, but also focus on the needs and demands of contemporary global markets. In a nutshell, we should take the ‘think local but act global’ route, and follow not only ‘Make in India’ but also ‘Make for the World’.‘CoronaOven’ is the latest product introduced in the market by Log 9 Materials in an attempt to prevent or limit the threat of surface-to-human-transmission of COVID-19; it is a scientifically-designed disinfection /sanitisation chamber which makes use of multi-focal UV-C rays to kill Coronaviruses and other pathogens it takes as low as two minutes (after any object is placed inside the chamber).Log 9 has already deployed a number of variants of its ‘CoronaOven’ product in hospitals, police stations, airports, among other public spaces across India, and is now extending footprints to the European and American markets. As a first step towards this goal, Log 9 has collaborated with Versailles, France-headquartered SSI Group — a conglomerate dealing in surveillance and security solutions — to process bulk orders for multiple clients in France. SSI Group has already placed orders for a few paid samples of CoronaOven; notably, one of these initial samples will be placed at Élysée Palace, i.e. the President of France Emmanuel Macron’s official residence.Akshay Singhal, Founder & CEO, Log 9 Materials said, “While outlining his vision and agenda for Aatmanirbhar Bharat or Self-reliant India, PM Modi highlighted ‘technology-driven systems’ as one of the five key pillars that will drive the required transformation for the nation, and we can’t agree more with him on this. Likewise, in combating the Coronavirus spread and for flattening the curve, science and technology-oriented innovations like CoronaOven are expected to play a big role in the coming days and months.”Singhal added, “We at Log 9 are determined to ensure that a life-saving yet cost-effective solution like CoronaOven should reach far and wide and benefit maximum number of front-end Corona warriors and the humanity at large; this is why we have now decided to export the product to international buyers and communities. To this end, we recently got the CE mark certification for our product, and are currently receiving queries for CoronaOven from several European countries. Meanwhile, some institutional buyers from Canada are also in the process of buying the product samples, and our next port of call shall be the US market.”For many years, artificially generated UV-C ray has emerged as a staple method of sterilisation; the process is known as ultraviolet germicidal irradiation (UVGI) and is being used in hospitals, offices and factories, flights, etc. CoronaOven has been built on the same scientific principle and also further validated by an US FDA study which demonstrates that controlled UVC light can permanently damage the RNA sequence of SARS-CoV1 virus. Till date, Log 9 is already manufacturing more than 200 units of CoronOven per day. The company expects to scale up production to 500+ units by the next month, while also optimising the supply chain, increasing exports, and hence positioning CoronaOven as a globally-accepted product from India.

SHANGHAI – The HSBC Champions has a familiar look to Graeme McDowell, with a few exceptions. He goes into the weekend at Sheshan International in contention for a World Golf Championship, with Ian Poulter and a big-hitting American alongside. Only, now, the American is Masters champion Bubba Watson – not Dustin Johnson, who overpowered the course on his way to victory last year. And at least this time, McDowell has the lead. McDowell leaned on a hot putter to carry him to another 5-under 67 on Friday. That gave him a three-shot lead over Poulter, with Watson and Hiroshi Iwata of Japan right behind. Tournament organizers might be missing the presence of Johnson, the defending champion who is on a ”voluntary leave” for what he described as personal challenges. Just don’t count McDowell among them, especially not the way Johnson set the tournament record at 24-under 264. ”He looked unbeatable last year the way he played this golf course,” McDowell said. ”But we’ve got a fairly decent replacement in Bubba, who in his own way has got the same kind of talents as Dustin, the way he drives it and the short game. In many ways, it’s a very similar scenario – myself and Poults against the long-hitting American.” McDowell saved par when he had to and strung together back-to-back birdies early and late in his round to reach 10-under 134. Poulter and Watson showed that a deficit can be made up quickly, particularly on the dynamic finishing holes at Sheshan International. WGC-HSBC Champions: Articles, videos and photos Watson was seven shots behind when he made birdie on the par-5 14th, and he was just getting warmed up. He blasted a drive just through the end of the fairway on the 487-yard 15th hole and hit gap wedge to 8 feet for birdie on the 15th. He chipped in twice for birdie on the next two holes, and had a simple up-and-down on the par-5 18th to end his round of 67 with five straight birdies. ”Hit some good shots but couldn’t make some putts. Hit some bad shots and made some putts,” Watson said. ”It was a great last five holes.” Poulter was five shots out of the lead when he birdied four of the last five holes – he made par on the par-3 17th – for a 67 that put him three shots back. ”Probably the best I’ve played all year, which is very exciting,” Poulter said. ”It was a little frustrating the first 13 holes that I was missing chances, but four birdies in the last five holes … chances started to go in at the end and I’m very happy.” Rickie Fowler opened with 14 straight pars, added a few birdies and shot 70 to reach 5-under 139, along with Tim Clark (70), Jonas Blixt (68) and Kevin Na (68). McDowell is not one to complain about a pair of 67s on any golf course, though they were different. He only missed one fairway in the opening round, which set up plenty of birdie chances. He had to scramble more on Friday, though at least he could rely on his putter. ”I have to improve tee-to-green to have a chance on Sunday,” McDowell said. ”I’m putting great – I love these greens. I’ve just got to keep doing it. I have to go out there tomorrow and not think about making mistakes. Just have to keep the pedal down, execute my game plan, and give myself a chance to win on the back nine on Sunday.” Adam Scott might have cost himself a chance with a wild round. The Australian opened with four birdies through seven holes to get within a shot of McDowell. A poor tee shot changed everything. He pulled his drive into a water hazard on the 603-yard eighth hole and had to drop at one of the forward tees. Trying to reach the green in two, he came up just short of the creek in front of the green, and then his pitch from gnarly rough didn’t quite reach the green and rolled into the hazard next to a large rock. Scott decided to take a penalty drop from the other side of the creek and made a quadruple-bogey 9, wiping out those four birdies. He followed with an approach into the water on the ninth for a double bogey, and made eagle on the back nine to salvage a 72. He still was eight shots behind. Poulter liked his position much better. ”We’ve got 36 holes to go. You’ve got 36 potential birdies,” he said. ”So three shots is pretty close.”
That Tennessee is perhaps tougher than people thought and that Alabama can win in multiple ways.The Vols had lost eight straight to this archrival by an average margin of 23.5 points and a famous Southern rivalry teetered on the cusp of irrelevance. Tennessee’s gritty performance Saturday in Tuscaloosa injected new life in the tradition-bound game, putting up a ferocious fight until Tide RB Derrick Henry took a pitch and rumbled into the end zone with 2:24 left to put Bama ahead for good, 19-14.Henry finished with 143 yards and two touchdowns, a second consecutive sterling performance for the outstanding back who has been overshadowed this season by LSU’s Leonard Fournette. They were hard-earned yards for Henry, as the Tennessee defensive line played its heart out.But if Alabama’s old-fashioned formula of power football wasn’t enough to crush Tennessee, the Tide showed it had other offensive tools that make it even better. Down 10-7 in the fourth quarter, Bama QB Jake Coker led a drive that overcame penalties of 15 and 10 yards and finished with a touchdown to put the Tide ahead 13-7 with 7:08 remaining. On the winning drive, Coker converted third downs on touch passes to his right and his left.Alabama has a bye week before its home showdown with LSU on Nov. 7. In addition to the rest, the Tide will savor the knowledge it is a team that can blend finesse to complement its muscle.
