Landfill sparks alarm after test reveals toxic chemicals exceed safe limits: 'The plume size is completely unknown'
Advocacy group Friends of Rocky Top had previously called out other environmental problems at the Rocky Top Environmental landfill near Yakima, per Northwest Public Broadcasting. The concerns included fire, pungent odors, and airborne litter.
Now, it's worried that soil tainted with per- and polyfluoroalkyl substances and dumped at the site has contaminated groundwater. In response to protests by the group, the landfill set up monitoring wells, and testing showed PFAS levels surpassed cleanup levels. One well tested at 21 nanograms per liter; the Environmental Protection Agency considers levels of 4 nanograms per liter too high, per the report.
"The amount of the contamination and the plume size is completely unknown," said Scott Cave, a consultant for Friends of Rocky Top, according to Northwest Public Broadcasting. "We have no idea where that plume is gone or if we're even going to find it in neighbors' wells."
PFAS are a group of human-made chemicals that are found in a variety of consumer products including nonstick cookware and water-repellent clothing along with firefighting foams. Exposure to these substances has been associated with a number of negative health impacts. For instance, one study found that exposure to PFAS through drinking water before birth could lead to an increased risk of childhood cancers. Another paper tied these chemicals to an increased risk of cardiovascular diseases in postmenopausal women.
Meanwhile, these chemicals are all around us. For instance, one study found that over 20% of Americans may be exposed to detectable levels of PFAS in their tap water, and the Agency for Toxic Substances and Disease Registry says most Americans have been exposed to PFAS and have it in their blood.
In April 2024, the EPA issued its first national and legally enforceable drinking water standard for PFAS, part of the agency's PFAS Strategic Roadmap. However, it is unknown how the EPA will move forward with PFAS regulations under the Trump administration. For instance, in February, the administration rescinded a proposed rule that would have set national limits on the discharge of PFAS into waterways.
However, some states are taking action to protect residents. For one, Minnesota recently enacted a law that prohibits the willful addition of PFAS to 11 product categories, including cleaners, mattresses, automotive maintenance products, cookware, and other items. The law will expand to ban nearly all uses of PFAS by 2032.
You can help reduce your exposure by opting for PFAS-free brands and limiting your purchases of nonstick cookware as well as stain- and water-resistant clothing.

Samples before space suits: America must be smart about its mission to Mars
On day one of this administration, the president included his ambitions for Mars in his inaugural address, and again several weeks later to a joint session of Congress: 'We are going to conquer the vast frontiers of science, and we are going to lead humanity into space and plant the American flag on the planet Mars, and even far beyond.' President Trump's vision for Mars is correct, and now there is a plan for the next steps in how he achieves it. The U.S. has led the world in the exploration of Mars since Vikings I and II landed in 1976. We now stand on the precipice of two ultimate achievements: the return of samples from Mars to Earth, and sending the first humans — Americans — to the Martian surface. The fiscal 2026 presidential budget request proposed 'to terminate the Mars Sample Return Program given that current architecture options remain unaffordable.' But, it adds: 'It is anticipated that future missions to Mars will return samples for study on Earth.' We need those samples robotically returned for study on Earth. Delaying Mars Sample Return or waiting for astronauts to pick them up will make the human exploration of Mars significantly more expensive and dangerous — and for the first time ever, almost certainly cede decades of U.S. space exploration leadership to China. A lower-cost robotic Mars Sample Return would more than pay for itself from savings realized by simplified human missions. Martian soil has substances known to be toxic, as well as uncharacterized biological potential. Without Mars Sample Return, human mission designs must account for the full range of possibilities and the most demanding scenarios. Laboratory tests are needed to make direct measurements of the Mars samples to determine concentrations and forms of toxic materials to understand threats and develop solutions. This will be needed to design spacesuits and protect astronauts from the fine martian dust. It allows risk mitigation to shift from large and expensive requirements to quantifiable ones with reduced uncertainties. While no martian life has been detected yet, our exploration has shown that much of Mars would previously have been habitable, and parts of Mars may currently still be habitable. In advance of humans to Mars, we need to robotically return samples in a highly controlled manner to satisfy planetary protection back-contamination requirements to ensure that Mars does not have organisms that might impact human health or have adverse effects on Earth's biosphere. Mars Sample Return will accelerate U.S. leadership in space. Mars is several hundred times farther from Earth than the Moon. Using current propulsion technologies, a Mars round trip will take up to three years, with minimal abort opportunities, as compared to Apollo's round trip of days. Even then, there were three uncrewed and four crewed missions before Apollo 11, the first Moon landing. Completing Mars Sample Return supports technology demos needed for human missions, such as advancing from the current precision landing (7-10 km) to pinpoint landing (~100 m) to put astronauts in proximity to safe sites and pre-positioned supplies. Mars Sample Return also achieves a profound international first: the first samples — with potential for evidence of life — returned from Mars. These samples might once and for all answer the fundamental question of 'Are we alone in the universe,' and that is a question we most certainly want the United States to answer first. Lockheed Martin, my former employer, has been studying Mars Sample Return missions for more than 50 years, and is confident it can deliver an end-to-end architecture for under $3 billion — less than half of previous estimates — by leveraging heritage components, reducing design complexity, and streamlining the program structure. They have built and flown four highly successful Mars landers and four highly successful Mars orbiters, as well as pioneered all three of NASA's previous sample return missions (returning material from a comet, the solar wind and an asteroid), and have established credibility and mission success across a wide variety of additional deep space missions, from Venus to Saturn. NASA's Mars 2020 rover, Perseverance or 'Percy,' at Jezero Crater has been caching an unparalleled set of samples that will shed more light on the history of Mars than all previous Mars missions combined. China has announced it plans to launch a sample return mission to Mars in 2028, with an Earth return likely in 2031. If we forgo the timely return of Percy's superior set of samples, it will be China that leaps ahead. Mars soil and dust are uniquely different, and potentially dangerous — returning samples should precede astronauts going to Mars, while also maintaining our nation's pre-eminence in Mars exploration as NASA lays the groundwork for the next giant leap. Ben Clark has been a member of the science teams of every NASA mission to explore the surface of Mars, and designed the instrument on Viking that made the first analysis of martian soil. He was chief scientist for deep space exploration at Lockheed Martin. Currently, he helps analyze chemical compositions of the diverse samples the Perseverance rover has been acquiring during its multi-year trek on Mars.

A toxicologist's guide to poison ivy's itch and bee stings' burning pain – 2 examples of nature's chemical warfare
Enjoying the outdoors carries the danger of running into nature's less-friendly side: toxic plants and animals. As toxicologists at the University of Virginia's Blue Ridge Poison Center, we see many patients each year suffering from itchy rashes from poison ivy and stings from wasps or bees. Plants and animals deploy toxins most often in order to defend themselves. Learning how they do that and what happens when the human body is exposed to these substances can offer insights on how to prevent or manage these encounters with nature. The goal is not to scare people away from the outdoors, but to equip them with the knowledge to appreciate these organisms' intricate self-preservation strategies and to protect themselves in return. Whether in a remote state park or on a city playground, most people have encountered poison ivy. This plant is recognizable by its characteristic arrangement of leaves growing in groups of three with edges that vary from smooth to jagged. It can take many forms: a single small plant, a mass of ground cover, a small bush, or a climbing vine reaching many feet up a tree or building. READ: The molecule that makes you itch also stops inflammation Poison ivy – its scientific name is Toxicodendron radicans – and its close relatives poison oak and poison sumac contain an oily substance called urushiol. This chemical is found in every part of the plant: the leaves, roots, stems and even the small white berries it produces in late summer. About 75% of people will develop an allergic reaction on contact with urushiol. Urushiol has antimicrobial properties, and scientists think its job in the poison ivy plant is to protect it from diseases. Because it is so oily, urushiol spreads easily. It can transfer from the plant to your skin, clothes, garden tools or even your pets. Direct plant contact isn't the only risk: If urushiol is on your clothing or a pet's fur and your skin later brushes against it, you can develop the same rash as you'd get from directly touching the plant. Urushiol triggers a delayed allergic reaction. When the oil touches your skin, it binds to skin cells, changing their shape. A molecule called CD1a then clocks urushiol as a foreign substance, prompting the immune system to mount an attack on the cells – hence the rash. READ: Are twins allergic to the same things? The symptoms do not appear instantly; the rash usually appears 12 to 48 hours after exposure. It often starts as redness and itching, then develops into small bumps or fluid-filled blisters. The reaction can be mild or severe, depending on how sensitive you are and how much urushiol got on your skin. The rash itself isn't contagious. Fluid from the blisters doesn't spread it. What spreads the rash to other areas of your body or to others is the urushiol lingering on your skin, clothing, tools or pets. Once the oil is adequately washed away, the rash can't spread to other people or to other areas of your body. If you have touched poison ivy, wash the area as soon as you can with soap and water and change your clothes if possible. After that, the rash will eventually resolve on its own. You can help alleviate symptoms by using a topical steroid or anti-itch cream on the rash. In severe cases, or if the face is affected, patients may require oral steroids to treat the symptoms. Bees and wasps are most active in the late summer. Because of this, we receive more frequent poison center calls about them during this season. Bees and wasps generally sting to defend their hives or nests or to protect themselves from perceived threats. They store venom in their abdominal sacs. When they sting, the venom flows through their stinger and is injected into their target's skin. This venom is a clear, slightly acidic liquid loaded with various active ingredients. For example, it contains enzymes such as phospholipase A2 that break down cell membranes, and peptides such as melittin that cause pain. The venom also contains natural chemicals such as histamine and epinephrine that affect blood vessels and the immune system. Unlike with poison ivy, where the immune system's reaction to the substance causes irritation, with bee and wasp stings it's primarily the substance itself that causes pain – although immune response can still play a role. As soon as the venom enters a person's skin, their body reacts. READ: Are you really allergic to penicillin? A sharp, burning pain comes first as the components of the venom begin to inflict damage, followed by redness and then swelling of the area. Symptoms commonly peak within a few hours and fade within a day. However, some people have stronger reactions with larger areas of swelling that can last for several days. This is because everyone's immune system is slightly different, and some people tend to have stronger reactions than others to foreign substances. In rare cases, the immune system overreacts, releasing large amounts of histamine and other chemicals all at once. Histamine is most often released in response to a foreign substance, causing symptoms of an allergic reaction. This can lead to anaphylaxis, a severe allergic reaction that can make breathing difficult, lower blood pressure and cause airway swelling, and which can quickly become life-threatening. READ: How to manage hay fever in your pets Getting stung multiple times at once can also be life-threatening due to the sheer amount of venom injected, even in people without a bee venom allergy. If you're stung and the stinger is stuck in the skin, it should be removed immediately by the quickest means available. Bee stingers are barbed and can continue to deliver venom for up to a minute. Most bee or wasp stings require only symptomatic treatment, such as an over-the-counter steroid cream or oral antihistamine to reduce itching and swelling. However, people who begin to develop more severe symptoms such as full body hives, vomiting or difficulty breathing should immediately seek emergency care. Anaphylactic reactions require rapid treatment with a medication called epinephrine and close monitoring in the hospital. Christopher P.
