Hoosiers Urge EPA to Uphold Strong Coal Ash Regulations at Public Hearing

Hoosiers Urge EPA to Uphold Strong Coal Ash Regulations at Public Hearing

Residents of Indiana, known as Hoosiers, attended a public hearing held by the Environmental Protection Agency (EPA) to voice their opposition to weakening coal ash regulations. The hearing addressed Indiana's proposed Coal Ash permitting program, which critics argue would allow the state to bypass federal protections in favor of less stringent statewide rules. Indiana has the highest number of coal ash dumps in the U.S., with over 100 landfills and ponds containing approximately 134 million cubic yards of toxic coal ash. Environmental groups like the Sierra Club contend that the Indiana Department of Environmental Management (IDEM) has a history of permitting dangerous coal ash contamination, and approving their application would leave communities vulnerable to further pollution.

EPA Accelerates Soil Cleanup at PCE Southeast Contamination Superfund Site in York, Nebraska

EPA Accelerates Soil Cleanup at PCE Southeast Contamination Superfund Site in York, Nebraska

The U.S. Environmental Protection Agency (EPA) has successfully met its soil cleanup objectives for Operable Unit 01 at the PCE Southeast Contamination Superfund site in York, Nebraska. This achievement is part of the EPA's Superfund Solutions initiative, which aims to expedite the remediation of contaminated sites. The agency utilized in-situ thermal remediation, an innovative technology that heats contaminated soil to convert pollutants into vapor for treatment, significantly reducing the cleanup timeline by over a decade. This method proved to be more efficient and less disruptive than traditional soil removal techniques. Laboratory analyses have confirmed that tetrachloroethene (PCE) levels in the soil at Operable Unit 01 now meet the established cleanup goals. EPA Region 7 Administrator Jim Macy highlighted that this accelerated approach minimizes community impact while effectively restoring the site. Cleanup goals for Operable Unit 02 were met in 2025, and efforts will now shift to addressing the con...

Albany Park Launches Volunteer-Led Rat Birth Control Program to Combat Infestation

Albany Park Launches Volunteer-Led Rat Birth Control Program to Combat Infestation

Albany Park, a neighborhood in Chicago, has initiated a volunteer-driven rat birth control program to address its significant rat infestation. This program involves residents, such as Lark Digges-Elliot, who were concerned about the rat problem and sought non-toxic solutions. Volunteers are trained to maintain 40 rat birth control bait boxes distributed throughout the area. Each week, these volunteers replace plant-based sausages, made with cottonseed oil, inside the bait boxes. This method aims to reduce fertility in both male and female rats over time. Albany Park is the third Chicago neighborhood to partner with the Arizona-based company SenesTech for this initiative, following Lincoln Park and the Wicker Park-Bucktown area. The bait boxes are strategically placed in alleyways along commercial corridors and near the Kimball Brown Line train station, with entrances specifically designed for rats.

New Research Links Paraquat Herbicide Inhalation to Parkinson's Disease in Mice, Raising Regulatory Concerns

New Research Links Paraquat Herbicide Inhalation to Parkinson's Disease in Mice, Raising Regulatory Concerns

Preliminary new research from scientists at the University of Rochester and the University of Georgia indicates that exposure to paraquat herbicide through inhalation can cause neurotoxic brain effects consistent with Parkinson's disease. The study, which is a preprint and has not yet undergone peer review, exposed laboratory mice to air containing paraquat particles for 60 days. The results showed reduced dopamine neurons and impaired motor function in the mice. This research is significant because it models human exposure more closely than previous studies, which often involved dietary or injected paraquat. Deborah Cory-Slechta, a neurotoxicologist and co-author, stated that these findings strengthen the existing body of evidence linking paraquat to Parkinson's. The study also noted greater impacts in male mice, mirroring the higher diagnosis rate of Parkinson's in men. This comes as U.S. regulators are reportedly re-examining the chemical, which is banned in approximately 70 other countries, including C...

EPA Demonstrates New Lead Identification Technologies to Combat Exposure

EPA Demonstrates New Lead Identification Technologies to Combat Exposure

The Environmental Protection Agency (EPA) recently hosted a demonstration of emerging technologies aimed at improving the identification of lead service lines. The event took place at the EPA’s Lead Service Line Identification Test Bed in Edison, New Jersey. Researchers from Dartmouth College showcased their electromagnetic induction (EMI) technology, which uses electromagnetic fields to differentiate pipe materials like lead and copper without excavation. Drexel University’s team presented their stress wave technology, which employs mechanical vibrations to locate lead service lines by analyzing signals captured by ground sensors. These innovative methods promise to identify lead service lines more quickly, affordably, and with less disruption than traditional excavation techniques. According to Teresa Booeshaghi, associate administrator of the Office of Applied Science and Environmental Solutions (OASES), the test bed provides a crucial space for evaluating these technologies under controlled conditions ...

Arizona County Faces Heightened PFAS Contamination Risks Amid New Mine Approval

Arizona County Faces Heightened PFAS Contamination Risks Amid New Mine Approval

Santa Cruz County, Arizona, is grappling with severe perfluoroalkyl and polyfluoroalkyl substances (PFAS) contamination, ranking first in Arizona and tenth nationally for these 'forever chemicals.' Environmental activists are raising alarms as South32's Hermosa mine in Patagonia received federal approval under new fast-track 'critical mining' rules. Critics, including Robin Lucky, president of the Calabasas Alliance, fear the mine will exacerbate existing pollution by releasing arsenic and other heavy metals. The county's public drinking water systems already show unacceptable levels of PFAS in 44% of cases, according to the Arizona Department of Environmental Quality. The Nogales Wash, which carries wastewater and storm runoff from Mexico, is a significant source of contamination, with PFAS not adhering to political boundaries. Despite company assurances from President Pat Risner that arsenic levels are decreasing and that a high reading for another toxic metal was due to a lab error, activists remain con...

Court Rejects Government's Power to Dismiss Citizen Suits in X.AI Data Center Case, Impacts Environmental Litigation

Court Rejects Government's Power to Dismiss Citizen Suits in X.AI Data Center Case, Impacts Environmental Litigation

A U.S. District Court has issued two significant rulings in the National Association for the Advancement of Colored People’s (NAACP) lawsuit against X.AI Corp. regarding its data center in Southaven, Mississippi. The NAACP alleges that the MZX Colossus Gas Plant, which powers an X.AI data center supporting the Grok platform, operates in violation of the Clean Air Act due to unpermitted portable gas turbines. In an October 19, 2026 decision, the court rejected the U.S. government's motion to intervene and unilaterally dismiss the NAACP's claims, stating that the Clean Air Act does not grant the government such power. The government had argued that its right to intervene included the right to dismiss citizen suits and that allowing such suits to continue would intrude on its enforcement discretion. In a subsequent October 30, 2026 decision, the court also denied X.AI's motion to dismiss, ruling that the turbines, despite being mounted on trailers for portability, are not 'mobile sources' exempt from permitti...

EPA Demonstrates Emerging Technologies for Lead Service Line Identification

EPA Demonstrates Emerging Technologies for Lead Service Line Identification

The U.S. Environmental Protection Agency (EPA) recently conducted its inaugural public demonstration of emerging technologies aimed at identifying lead service lines. This event took place at the EPA's Lead Service Line Identification Test Bed in Edison, New Jersey. The primary goal of these technologies is to reduce the need for extensive excavation, lower costs, and decrease labor associated with identifying lead pipes. Researchers from Dartmouth College and Drexel University showcased two distinct methods. Dartmouth presented electromagnetic induction (EMI) technology, which uses electromagnetic fields to detect and analyze responses from buried metal pipes, allowing for material identification without direct exposure. Drexel demonstrated stress wave technology, which involves generating mechanical vibrations by striking an accessible service line valve. Ground sensors then capture signals traveling through the pipe and surrounding soil to differentiate between lead and non-lead materials. The EPA estab...
