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 [...]

Report: Drilling spills ruined wells and polluted streams in Westmoreland, across Pennsylvania

Source: Report: Drilling spills ruined wells and polluted streams in Westmoreland, across Pennsylvania | TribLIVE.com Edward Mioduski holds a jar of water produced by his Loyalhanna Township well in June 2017, a month after the water became polluted during drilling underneath nearby Loyalhanna Lake. Alice and Edward Mioduski point to where the Mariner East II pipeline cuts across their farm in Loyalhanna Township. It has been more than four years since Edward and Alice Mioduski of Loyalhanna Township have been able to drink water from their well near Loyalhanna Lake. Drilling mud mixed with the mineral bentonite leaked from the hole that Sunoco Pipeline L.P. was boring underneath the lake in May 2017. It bled into the aquifer that their 95-foot-deep well had tapped into for decades. The crystal-clear water turned cloudy gray with little white blobs floating around. “Within a short time, it went to hell,” Alice Mioduski said. Before that, their water was “the nectar of the gods. We never ran out of water.” Now, they have a 1,500-gallon plastic tank in their backyard that provides water for showering and washing clothes — when it doesn’t freeze in the winter — paid for by Sunoco. A filtration system inside the house provides water for drinking and cooking. The damage to streams and water supplies by the leaks and lost fluids during construction of the 307-mile Mariner East II pipeline is outlined in a 64-page indictment handed down last week by a statewide investigating grand jury. Energy Transfer L.P. of Dallas, a successor to Sunoco Pipeline, was slapped with 48 criminal violations of the Clean Streams Law. Fluids that were to return to the surface and be dumped into a drill pit for reuse simply disappeared underground or bubbled up to the surface. The grand jury alleges [...]

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 [...]

South Dakota Homeowners Sue County Over Sinkhole Risks

Source: South Dakota Homeowners Sue County Over Sinkhole Risks More than 150 homeowners in a development outside Rapid City, South Dakota, are suing Meade County over risks to their properties after a sinkhole exposed an abandoned gypsum mine. The federal complaint filed Sept. 27 by Hideaway Hills residents in Black Hawk seeks damages to be determined by a jury and other relief “allowed by law or equity.” The sinkhole forced about 40 residents from 15 homes in April 2020. Geotechnical studies show there could be water flowing through the abandoned mine and toward Interstate 90 and there is the potential for future sinkholes, the Rapid City Journal reported. The complaint alleges several violations of the state Constitution. It says the decision to approve the subdivision by the county Planning Commission and the Meade County Commission put homeowners at risk. “Without the decisions to approve the subdivision, issue building permits and certificates of occupancy, the opportunity for harm would not have existed,” the complaint states. Developers allegedly informed the county in 2001 of an underground gypsum mine and discussed taking steps to determine if it was safe to build on. The commission approved the subdivision proposal in 2003. Katelyn Cook, an attorney for the county, said her legal team does not comment on pending litigation. South Dakota isn't the only area that suffers from sinkholes. Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania tend to have the most damage from sinkholes.

Sustainable solution to mining’s ‘red mud’ waste enters final stage of testing

Source: Sustainable solution to mining’s ‘red mud’ waste enters final stage of testing | Central Queensland Today University of Queensland has developed technology that could rehabilitate mine waste back to useful soil is entering full-scale trials. 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 [...]

Lancaster County sinkhole raises concern over detours, emergency responder response times

Source: Lancaster County sinkhole raises concern over detours, emergency responder response times | WHP LANCASTER COUNTY, Pa. — A nearly 20-foot sinkhole on State Route 324 (Marticville Road) between Sprecher Road and West Penn Grant Road in Lancaster County is causing detours for community members and concern over delays for emergency responders. PennDOT implemented a detour Sunday night, originally anticipating work to fill the sinkhole would begin in a month. PennDOT Engineering District 8 Press Officer Dave Thompson exclusively tells CBS 21 News’ Samantha York Thursday the timeline has extended. “We expect this road might be closed into next spring before we can actually start working on it,” Thompson says. “That’s- that’s news to me,” New Danville Fire Company Fire Chief Brad Shenk says. 20% of his 25 active volunteer firefighters live on the opposite side of the sinkhole and respond to emergencies from home in a rural town. He says being delayed for a few minutes can make a big difference when time is of the essence, requesting the sinkhole to be filled sooner. “It’s going to have an adverse effect on our response times to get those members here,” Shenk tells CBS 21’s Samantha York. “We’re a small fire company, we’re counting on everybody to go up at any given time, whoever’s available responds and these guys are going to be delayed by several minutes.” Community members speculate the sinkhole, which reaches from the middle of the road through a drainage ditch and into adjacent property, has something to do with new construction nearby. However, the cause remains undetermined by officials – which is causing the delay in getting it fixed. “We’ve assessed what needs to be done, but we need to get some- an agreement in place with a local property owner that’s property is adjacent to [...]

Gaming to improve geotechnical engineering education—and broaden diversity

Source: Gaming to improve geotechnical engineering education—and broaden diversity | Rowan Today | Rowan University A new research project at Rowan University’s Center for Research and Education in Advanced Transportation Engineering Systems (CREATES) aims to teach students real-world geotechnical engineering concepts and attract diverse candidates to the field using interactive video games. Called MERGE (Multiphysics Enriched Mixed Reality for Integrated Geotechnical Education), the project is led by Dr. Cheng Zhu, an assistant professor in the Department of Civil and Environmental Engineering; Dr. Ying (Gina) Tang, an expert in serious games and professor in the Department of Electrical and Computer Engineering; Dr. Sarah Ferguson, an assistant professor in the College of Education; Dr. Sarah Bauer, an assistant professor in the Department of Civil and Environmental Engineering; as well as collaborator Dr. Lei Wang, assistant professor of geotechnical engineering at the University of the District of Columbia, a historically Black college and university. Both universities are located on the East Coast of the United States near Delaware, New Jersey, Pennsylvania, Virginia, Maryland, and West Virginia. The study is supported by a $299,210 grant from the National Science Foundation. While college civil engineering programs nationwide focus on concepts like soil mechanics and geotechnical engineering, some course content and textbooks don’t reflect emerging technology and research methods. MERGE games will include real-world scenarios students are likely to encounter in internships and careers in the geotechnical engineering field. Because the games are computer-based, students don’t need access to a lab or expensive equipment, making the learning scenarios accessible anytime and anywhere. It is expected that such authentic, fun and engaging play in games will promote learning. “Most universities don’t really use games to teach students, especially in our field,” Zhu said. “When we design these games, we want to make it very different from the current efforts.” The [...]

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

Source: Reusable Ionic Liquid Enables Extraction of Precious Rare-earth Elements from Coal Fly Ash | School of Civil and Environmental Engineering Turnipseed Family Chair and Professor Ching-Hua Huang, left, and Ph.D. candidate Laura Stoy, right, published research outlining a new method for extracting rare-earth elements from coal fly ash. By Melissa Fralick Researchers from Georgia Tech’s School of Civil and Environmental Engineering have discovered a way to extract rare-earth elements—essential ingredients for nearly all modern electronics—from the ash left behind at coal-burning power plants using a non-toxic ionic liquid. 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 [...]

UD researchers study climate change impacts on soils at military installations

Source: The Ground Underfoot - Civil and Environmental Engineering UD researchers study climate change impacts on soils at military installations We walk over it, drive over it and build on it. Yet, it is probably safe to say, most of us rarely think about the ground beneath our feet. Underneath the grass, concrete, asphalt and other materials in our built environment, however, soil provides structure and stability for what lies above. The United States military wants to understand the role that climate impacts, such as flooding, storm surge or sea level rise, will have on soils at its coastal military bases and facilities, which are critical to national security. Soil conditions can affect the integrity of the ground underpinning buildings, roads, bridges and more. For example, if a soil’s pH were to rise significantly, due to increased salt content-containing ions such as sodium from storm surge, it could create saline conditions that could hamper the ground’s ability to support this necessary infrastructure. Understanding these threats will enable faster and more accurate routing and maneuverability for U.S. forces. The Delaware Environmental Institute (DENIN) is collaborating with the Engineer Research and Development Center (ERDC) of the U.S. Army Corps of Engineers and Louisiana State University to understand how vulnerable military installations along coasts may be affected by soil changes due to sea level rise and coastal flooding. DENIN has received $3.79 million in first- and second-year funding from the U.S. Department of Defense to start this work, and is eligible for an additional $3.82 million in continued funding over the following two years. Led by DENIN Director Don Sparks, Unidel S. Hallock du Pont Chair of Soil and Environmental Chemistry in UD’s Department of Plant and Soil Sciences, the UD effort includes interdisciplinary collaboration with Yan Jin, Edward F. and Elizabeth Goodman Rosenberg Professor [...]

3D Finite Element Analysis of a Contiguous Pile Wall

Source: 3D Finite Element Analysis of a Contiguous Pile Wall Source: RS3 | 3D Finite Element Software For Advanced Analysis | Rocscience 3D Finite Element Analysis of a Contiguous Pile Wall Introduction This article provides a brief summary of a 3D finite element analysis carried out using RS3 to model a contiguous pile retaining wall at the site of a proposed commercial development in the UK. The development site is located on sloping ground approximately 35 m from a motorway cutting. Due to the sloping topography of the site, cut and fill earthworks are to be undertaken to form a level development plateau upon which a large warehouse is to be built. This will require the construction of a circa 400 m long contiguous pile retaining wall to support the ground along the site’s upslope boundary where ground levels will be reduced by up to 8.4 m. Wall Design A plan showing the arrangement of the piles and the 2.0 m wide by 0.8 m deep capping beam is shown in Figure 1. The main 900 mm diameter piles are 17 m long and are staggered in a zigzag arrangement at 0.25 m offsets either side of the capping beam centerline. Interspersed mid-way between the main piles are 600 mm diameter infill piles. The infill piles are located along the capping beam centerline and are 11 m long. Figure 1: Pile and capping beam arrangement Ground Conditions The ground conditions are summarized in Figure 2 which shows a 2D section perpendicular to the wall alignment at the location where the retained height attains its maximum value of 8.4 m. The succession of strata comprises a veneer of clay-rich Glacial Till overlying Coal Measures bedrock. The Coal Measures bedrock is dominated by siltstone and mudstone and has been divided into three [...]
