Large Swath of Texas Oil Patch Rapidly Sinking and Uplifting, Study Finds
West Texas is already home to two giant sinkholes near the town of Wink caused by intensive oil and gas operations. Now, according to an unprecedented study, the "Wink Sinks" might not remain the last in the region.
Geophysicists at Southern Methodist University (SMU) in Dallas have found rapid rates of ground movement at various locations across a 4,000-square-mile swath around the two sinkholes. This area is known for processing extractions from the oil-rich Permian Basin.
The scientists made the discovery after analyzing radar satellite imagery taken between November 2014 and April 2017. Combined with oil-well production data from the Railroad Commission of Texas, the researchers concluded that the area's sinking and uplifting ground is associated with decades of oil activity and its effect on rocks below Earth's surface.
"Based on our observations and analyses, human activities of fluid (saltwater, CO2) injection for stimulation of hydrocarbon production, salt dissolution in abandoned oil facilities, and hydrocarbon extraction each have negative impacts on the ground surface and infrastructures, including possible induced seismicity," the study, published in the journal Scientific Reports, says.
Two massive sinkholes about a mile apart from the other in West Texas. The first "Wink Sink" opened up in 1980 and is about as wide as a football field. The second and larger hole opened in 2002 and stretches around 900 feet at the widest point.Google Earth
One location saw as much as 40 inches of movement over the past two-and-a-half years, the geophysical team found.
"The ground movement we're seeing is not normal," said co-author Zhong Lu, a professor in the Roy M. Huffington Department of Earth Sciences at SMU. "The ground doesn't typically do this without some cause."
The latest findings build on the team's 2016 report that revealed the existing "Wink Sinks" are expanding and new ones are forming.
Radar detected significant ground sinking a half-mile east of the huge Wink No. 2 sinkhole, where there are two subsidence bowls, one of which has sunk more than 15.5 inches a year. The rapid sinking is most likely caused by water leaking through abandoned wells into the Salado formation and dissolving salt layers, threatening possible ground collapse.

The region is populated by four counties and six towns, in addition to a vast network of oil and gas pipelines and storage tanks.
"These hazards represent a danger to residents, roads, railroads, levees, dams, and oil and gas pipelines, as well as potential pollution of ground water," Lu warned. "Proactive, continuous detailed monitoring from space is critical to secure the safety of people and property."
The researchers suggested that ground instability could be occurring in areas outside the ones surveyed.
"Our analysis looked at just this 4,000-square-mile area. We're fairly certain that when we look further, and we are, that we'll find there's ground movement even beyond that," said study co-author and research scientist Jin-Woo Kim.
"This region of Texas has been punctured like a pin cushion with oil wells and injection wells since the 1940s and our findings associate that activity with ground movement."

In response to the study, Todd Staples, president of the Texas Oil & Gas Association, told Dallas News: "Subsidence and uplift are found in many areas and the variety of conditions described in the report obviously require additional research to properly reflect on the situations."
"We look forward to reading the report in depth and will continue to produce oil and natural gas responsibly and safely, and in compliance with science-based rules and regulations."

In the midst of a pandemic, sales of cleaning products have skyrocketed, and many feel a need to clean more often. Knowing what to look for when purchasing cleaning supplies can help prevent unwanted and dangerous toxics from entering your home.
1. Fragrance – Avoid It<p>One of the fastest ways to narrow down your product options is immediately eliminating any product that promotes a fragrance, or parfum. That scent of "fresh breeze" or lemon might initially smell good, but the fragrance does not last. What does last? The concoction of various undisclosed and unregulated chemicals that created that fragrance.</p><p>Many fragrances contain phthalates, which are linked to many health risks including reproductive problems and cancer.</p>
2. With Bleach? Do Without<p>Going scent-free should have narrowed down your options substantially – now, check the front of the remaining packaging. Any that include ammonia or chlorine bleach ought to go, as these substances are irritating and corrosive to your body. While bleach is commonly known as a powerful disinfectant, there are safer alternatives that you can use in your home, such as sodium borate or hydrogen peroxide.</p><p>While you're at it, check if there are any warnings on the label – "flammable," "use in ventilated area," etc. – if the product is hazardous, that's a red flag and should be avoided.</p>
3. Check the Back Label<p>Flip to the back of the remaining contenders and check out that ingredient list. Less is more, here. Opt for a shorter ingredient list with words you recognize and/or can pronounce.</p><p>You may notice many products do not have ingredient lists – while this doesn't necessarily mean they contain toxic ingredients, transparency is key. Feel free to look up a list online, or stick to products that are open about their ingredients.</p>
4. Ingredients to Avoid<p>We already mentioned that cleaners containing fragrance or parfum, and bleach or ammonia should be avoided, but there are other ingredients to look out for as well.</p><ul><li>Quaternary ammonium "quats" – lung irritants that contribute to asthma and other breathing problems. Also linger on surfaces long after they've been cleaned.</li><li>Parabens – Known hormone disruptor; can contribute to ailments such as cancer</li><li>Triclosan – triclosan and other antibacterial chemicals are registered with the EPA as pesticides. Triclosan is a known hormone disruptor and can also impact your immune system.</li><li>Formaldehyde – Causes irritation of eyes, nose, and throat; studies suggest formaldehyde exposure is linked with certain varieties of cancer. Can be found in products or become a byproduct of chemical reactions in the air.</li></ul>
Cleaning Products and Toxics: The Bottom Line<p>Do your research. There are many cleaning products available, but taking these steps will drastically reduce your options and help keep your home toxic-free. Protecting your home from bacteria and viruses is important, but make sure you do so in a way that doesn't introduce other health risks into the home.</p><p><em>Reposted with permission from </em><em><a href="https://www.ehn.org/how-to-shop-for-cleaning-products-while-avoiding-toxics-2648130273.html" target="_blank">Environmental Health News</a>. </em><a href="https://www.ecowatch.com/r/entryeditor/2649054624#/" target="_self"></a></p>

Returning the ‘Three Sisters’ – Corn, Beans and Squash – to Native American Farms Nourishes People, Land and Cultures
By Christina Gish Hill
Historians know that turkey and corn were part of the first Thanksgiving, when Wampanoag peoples shared a harvest meal with the pilgrims of Plymouth plantation in Massachusetts. And traditional Native American farming practices tell us that squash and beans likely were part of that 1621 dinner too.
Abundant Harvests<p>Historically, Native people throughout the Americas bred indigenous plant varieties specific to the growing conditions of their homelands. They selected seeds for many different traits, such as <a href="https://emergencemagazine.org/story/corn-tastes-better/" target="_blank" rel="noopener noreferrer">flavor, texture and color</a>.</p><p>Native growers knew that planting corn, beans, squash and sunflowers together produced mutual benefits. Corn stalks created a trellis for beans to climb, and beans' twining vines secured the corn in high winds. They also certainly observed that corn and bean plants growing together tended to be healthier than when raised separately. Today we know the reason: Bacteria living on bean plant roots pull nitrogen – an essential plant nutrient – from the air and <a href="http://www.tilthalliance.org/learn/resources-1/almanac/october/octobermngg" target="_blank" rel="noopener noreferrer">convert it to a form that both beans and corn can use</a>.</p><p>Squash plants contributed by shading the ground with their broad leaves, preventing weeds from growing and retaining water in the soil. Heritage squash varieties also had spines that discouraged deer and raccoons from visiting the garden for a snack. And sunflowers planted around the edges of the garden created a natural fence, protecting other plants from wind and animals and attracting pollinators.</p><p>Interplanting these agricultural sisters produced bountiful harvests that sustained large Native communities and <a href="http://dx.doi.org/10.1353/eam.2015.0016" target="_blank">spurred fruitful trade economies</a>. The first Europeans who reached the Americas were shocked at the abundant food crops they found. My research is exploring how, 200 years ago, Native American agriculturalists around the Great Lakes and along the Missouri and Red rivers fed fur traders with their diverse vegetable products.</p>
Displaced From the Land<p>As Euro-Americans settled permanently on the most fertile North American lands and acquired seeds that Native growers had carefully bred, they imposed policies that <a href="https://doi.org/10.1086/ahr/87.2.550" target="_blank">made Native farming practices impossible</a>. In 1830 President Andrew Jackson signed the <a href="https://guides.loc.gov/indian-removal-act" target="_blank">Indian Removal Act</a>, which made it official U.S. policy to force Native peoples from their home locations, pushing them onto subpar lands.</p><p>On reservations, U.S. government officials discouraged Native women from cultivating anything larger than small garden plots and pressured Native men to practice Euro-American style monoculture. Allotment policies assigned small plots to nuclear families, further limiting Native Americans' access to land and preventing them from using communal farming practices.</p><p>Native children were forced to attend boarding schools, where they had no opportunity to <a href="https://doi.org/10.5749/jamerindieduc.57.1.0145" target="_blank">learn Native agriculture techniques or preservation and preparation of Indigenous foods</a>. Instead they were forced to eat Western foods, turning their palates away from their traditional preferences. Taken together, these policies <a href="https://kansaspress.ku.edu/978-0-7006-0802-7.html" target="_blank" rel="noopener noreferrer">almost entirely eradicated three sisters agriculture</a> from Native communities in the Midwest by the 1930s.</p>
Reviving Native Agriculture<p>Today Native people all over the U.S. are working diligently to <a href="https://www.oupress.com/books/15107980/indigenous-food-sovereignty-in-the-united-sta" target="_blank" rel="noopener noreferrer">reclaim Indigenous varieties of corn, beans, squash, sunflowers and other crops</a>. This effort is important for many reasons.</p><p>Improving Native people's access to healthy, culturally appropriate foods will help lower rates of <a href="https://www.cdc.gov/vitalsigns/aian-diabetes/index.html" target="_blank">diabetes</a> and <a href="https://www.apa.org/pi/oema/resources/ethnicity-health/native-american/obesity" target="_blank">obesity</a>, which affect Native Americans at disproportionately high rates. Sharing traditional knowledge about agriculture is a way for elders to pass cultural information along to younger generations. Indigenous growing techniques also protect the lands that Native nations now inhabit, and can potentially benefit the wider ecosystems around them.</p>

Amid reports that oil industry-friendly former Energy Secretary Ernest Moniz remains under consideration to return to his old post in the incoming Biden administration, a diverse coalition of environmental groups is mobilizing for an "all-out push" to keep Moniz away from the White House and demand a cabinet willing to boldly confront the corporations responsible for the climate emergency.
