Oil wells in L.A. and Residential Health Problems

Source: Oil wells in L.A.: Nearby residents grapple with health problems Magali Sanchez-Hall, a Wilmington resident for over two decades, has struggled with asthma her entire life. She says the health issue stems from her proximity to oil and gas drilling. Emma Newburger | CNBC LOS ANGELES, CALIF. — Stepping out of a coffee shop near Interstate 110 in the Wilmington neighborhood of Los Angeles, you’re immediately hit by a foul odor. Magali Sanchez-Hall, 51, who’s lived here for more than two decades, is used to the smell of rotting eggs wafting from the hundreds of oil wells operating in the neighborhood. She’s used to her neighbors describing chronic coughs, skin rashes and cancer diagnoses, and to the asthma that affects her own family, who live only 1,500 feet from a refinery. “When people are getting sick with cancer or having asthma, they might think it’s normal or blame genetics,” she said. “We don’t often look at the environment we’re in and think — the chemicals we’re breathing are the cause.” Wilmington, a predominantly working-class and Latino immigrant community of more than 50,000 people, has some of the highest rates of asthma and cancer in the state, according to a report by the non-profit Communities for a Better Environment. It’s surrounded by six oil refineries and wedged in by several freeways and the ports of L.A. and Long Beach. California, the seventh-largest oil-producing state in the U.S., has no rule or standard for the distance that active oil wells need to be from communities. For many Californians, especially Black and brown residents, acrid smells, noise and dirt from oil production is part of the neighborhood. Walking around Wilmington, pumpjacks are visible in public parks, next to schoolyards where children play and outside of people’s windows at home. At night, the sky is lit [...]

Shapiro files 48 charges against pipeline company for drilling spills

Source: Shapiro files 48 charges against pipeline company for drilling spills | City & State PA   Attorney General Josh Shapiro on Tuesday in Pennsylvania announced a slew of criminal charges against Energy Transfer Partners, the Texas-based company behind the construction of a controversial 350-mile natural gas pipeline that runs through 17 counties. Shapiro announced that his office filed 48 criminal charges against Energy Transfer for violating state environmental statutes, with 45 of the charges being for illegally releasing industrial waste throughout the state. The charges follow an 18-month investigation by a statewide grand jury which found that Sunoco Pipeline L.P. – which later merged with Energy Transfer – “criminally failed to properly report and address the environmental hazards created by its operations during the entirety of the pipeline project.” Shapiro said the charges stem from the illegal release of industrial waste at 22 different sites in 11 counties across the state. The grand jury’s findings detailed the release of hundreds of thousands of gallons of drilling fluid into lakes, waterways and residential areas since the pipeline’s construction began in 2017. Shapiro said upwards of 150 families suffered contaminated drinking water from construction of the pipeline. “Corporations should not be treated leniently just because there's not a mugshot of Energy Transfer being arrested today,” Shapiro said at a press conference. “They should be held accountable to the fullest extent of the law. That is what we are here to do – to apply the law without fear or without favor.” Shapiro announced the charges from Marsh Creek State Park in Chester County, which was polluted with between 21,000 and 28,000 gallons of drilling fluid just last year, according to the grand jury’s findings. A spokesperson for Energy Transfer did not immediately respond to a request for comment. The charges prompted some to [...]

HS2 tunneling machine completes first mile under the Chilterns

Source: HS2 tunneling machine completes first mile under the Chilterns The first 2,000 ton tunneling machine passed the one mile mark this week during the construction of the first tunnels for HS2. Launched in May, the 170m long Tunnel Boring Machine (TBM) covered the first mile cutting through a mix of chalk and flint beneath the Chiltern hills just outside London. The TBM – named Florence – is one of two identical machines excavating the twin ten-mile-long tunnels. A second machine, Cecilia, is a short way behind, with both TBMs expected to break out in around three years’ time. Designed specifically for the geology of the Chilterns, each machine is a self-contained underground factory, digging the tunnel, lining it with concrete wall segments and grouting them into place as it moves forward. Welcoming the progress, HS2 Ltd Project Client Rohan Perin said: “The 10 mile Chiltern tunnel will take HS2 underneath the hills and safeguard the woodlands and wildlife habits above ground as well as significantly reducing disruption to communities during construction and operation of the new railway. “Once complete, HS2 will offer low carbon journey options linking London with the major cities of the north and releasing capacity for more freight and local trains on our existing mainlines. It’s great to see how much progress has been made over the summer and I’d like to thank the crew of Florence and all the tunneling team for their hard work.” The first two TBMs are operated by HS2’s main works contractor, Align – a joint venture formed of Bouygues Travaux Publics, Sir Robert McAlpine, and VolkerFitzpatrick. A crew of 17 people keep the machines running, working in shifts and supported by over 100 people on the surface, managing the logistics and maintaining the smooth progress of the tunnelling operation.

University of Queensland has developed technology that could rehabilitate mine waste back to useful soil, with the technology now entering full-scale trials. Developed by researchers at UQ’s Sustainable Minerals Institute in partnership with Rio Tinto and Queensland Alumina Limited (QAL) the bio-engineering technology works by transforming bauxite residue, a by-product of alumina refining also commonly called ‘red mud’, into a soil-like material capable of hosting plant life. QAL Environment and Tailings Manager Trent Scherer said there was an excitement amongst the team to see the project move to a full-scale trial. “After years of watching various trials unfold within our daily work environment, to now be able to see the tangible outcomes of UQ’s work unfolding has been encouraging for the team,” he said. Mr Scherer said QAL were committed to minimizing their environmental footprint through their 5-YES program and the funding and resources provided to this project were further steps in that journey. In 2018 QAL commenced works for their 5-Year Environmental Strategy, comprising of 60 capital works projects and culture change initiatives. With a budget of $440 million designed to improve the environmental performance of QAL. This initiative with UQ is in addition to the 5-YES funding and QAL are hoping will pave the way for the future of tailings management. Ecological Engineering of Mine Wastes Group Leader Professor Longbin Huang said the technology would be trialed on an operational scale at two red mud sites in Queensland after the team secured new multi-million dollar funding agreements with Rio Tinto and QAL. “The technology demonstrates how transformative industry-academia partnerships can [...]

NASA grants UArizona $500,000 to research mining lunar resources

Source: NASA grants UArizona $500,000 to research mining lunar resources - Tucson, Arizona - Eminetra TUCSON, Ariz. — The idea of space mining is growing popular. Engineers at the University of Arizona are mapping out a plan to harvest the moon's resources. They’ll do so with a new excavation technique using autonomous robot swarms to mine lunar resources. The research team received a $500,000 two-year grant from NASA to advance space mining methods. “This is a really super exciting grant that is letting us really work in this domain of excavation, site preparation, and resource mining,” said Jekan Thanga, an associate professor for aerospace and mechanical engineering. Thanga developed a system called HEART to help with their research. It is an autonomous robotic system that will train robots to work together and improve over time. “It is also a system that cooperates with humans. So the humans work together with the system to identify new scenarios, identify with unknown scenarios, and then work together to sort of figure out a suitable solution,” said Thanga. A solution, for example, such as mining core from the moon. “To break this rock it takes enough power to light a 100 watt light bulb for about an hour. So if we're going to do the same thing on the moon, we’re going to need more efficient processes,” said Moe Momayez, the interim department head of mining and geological engineering. To mine and drill on the moon, Momayez developed a process that can drill through rock five times faster than any other method. “So water being a scarce commodity on the moon, we may have to modify our technique to use very little water or no water at all,” said Momayez. The team still considers humans a critical part of space exploration, but these robot [...]

Reusable Ionic Liquid from Coal Fly Ash Enables Extraction of Rare Elements

In a paper published in ACS’s Environmental Science and Technology on June 23, the Georgia Tech researchers showed that by applying an ionic liquid directly to solid coal fly ash, rare-earth elements can be successfully removed in a safe process that creates little waste. The study is co-led by Ching-Hua Huang, a professor of environmental engineering and Ph.D. candidate Laura Stoy. A third co-author, Victoria Diaz, is an undergraduate student who joined the lab as part of Georgia Tech’s Summer Undergraduate Research in Engineering/Sciences (S.U.R.E.) program. Rare-earth elements (REEs) are a set of 17 elements that are utilized to make everything from permanent magnets in windmills to LED screens for computers and smart phones. While rare-earth elements aren’t as scarce as their name implies, only a few locations around the globe have deposits large enough to mine directly. Many of these reserves are in politically sensitive locations, resulting in global supply chain tensions. “Right now, China produces over 80 percent of the world’s supply of rare-earth elements, meaning that if something were to happen to disrupt the global supply chain— like a ship getting stuck in the Suez Canal, or a pandemic, or a trade war with China—United States manufacturing might be cut off,” Stoy said. “Our work is one of many efforts to secure a [...]

Using Torque Testing for Better Designs

Source: Using Torque Testing for Better Designs All Engineers can relate to an experience we’ve had where what we designed was not how it turned out in “the real world”. Rarely does a project end up being exactly as what we put down on paper. Soil testing for foundation supports is no exception and unfortunately these differences almost never end on the positive side of a cost estimate. One way to mitigate those differences is to use a testing process which directly relates with the type of foundation being used. For helical piles, while there are well-established trends between ASTM D1586 N60 blow count N values and potential pile length, even the slightest variations in testing methods and/or soil description can create significant differences in the “design” versus “reality”. The more accurate method for a helical pile foundation design would be to do actual torque tests (a.k.a. helical probe tests) at the site. While most designs initially begin with a Geotechnical Report including boring logs, for helical piles using an actual torque test prior to start of work instead will provide a much more accurate picture of soil capacity and allow for a finite design. Even with boring logs and N60 blow counts being used for preliminary designs, a torque test can be used to “fine-tune” the foundation design. Many owners might think that the additional cost associated with a site torque test, albeit nominal, is not needed. However, time and time again, the small additional cost has proven to save substantial money on the foundation project by allowing the engineer to confirm and enhance their foundation design. In addition, site torque tests can be incorporated directly into a design created in the HeliCAP® v3.0 Helical Capacity Design software to provide real time updates to designs giving better solutions with more confidence. Adding actual [...]

Karst sinkholes form when the bedrock of the Earth is slowly worn away by erosion.[SLIDESHOW: How karst sinkholes form]Under the top soil is a layer called the overburden. Under that is bedrock, which may seem tough and solid, but it's actually filled with cracks and crevices water is constantly seeping through and infiltrating. As the water erodes the bedrock, the overburden starts to fall down into the space left behind. Years later, all that's left is a thin layer and the potential for a sinkhole to open up.However, if there's a slab over the surface you may not know there's a problem until it's too late. That's why Matt Dettman developed MSEDS, short for Mechanical Sinkhole Early Detection System. Dettman is a WKU Associate Professor of Civil Engineering [...]
