A multibillion-dollar measure that would help build, repair, and maintain a wide variety of water infrastructure projects sailed through the House Transportation and Infrastructure Committee Wednesday.
n article in the local newspaper caught Andrea Amico’s eye in May 2014. It reported that one of the three drinking-water wells at a sprawling business and industrial park nearby was shut down because of high levels of chemical contamination.
“Instantly, my heart sank,” says the Portsmouth, New Hampshire, woman. Amico recalls her reaction to the news: “My husband works there and he drinks water all day, and my two kids go to daycare there and they drink water all day.”
She’d never heard of the substances tainting the tap water—Portsmouth was one of the first communities in the US to discover these chemicals in public drinking water. Amico, who holds a master’s degree in occupational therapy and works in health care, started researching health effects from these contaminants and at first found little information.
Today, the situation has changed.
Senate Democrats want to know whether being exposed to PFAS chemicals, which have become ubiquitous in the environment, worsens the effect of the coronavirus on the human body.
US environmental regulators have decided they will not put restrictions on perchlorate – a rocket fuel ingredient known to harm fetal brain development – in drinking water. The Environmental Protection Agency argued that the federal government, states and public water systems have already taken proactive steps to reduce perchlorate levels.
Mounting public concerns and new state regulations in the U.S. are compelling water & wastewater utilities to address health risks associated with per- and polyfluoroalkyl substances (PFAS) – a class of pervasive chemicals found in drinking water and wastewater biproducts.
According to a new report from Bluefield Research, PFAS: The Next Challenge for Water Utilities, more than US $3 billion is forecasted to be spent annually on drinking water remediation technologies by 2030. While any significant increase in water treatment solutions hinges on federal policies, 29 states have already implemented a mix of policy directives, including testing requirements, prohibitions on product applications (e.g., food packaging), and the elimination of select fiirefighting foam constituents.
After decades of inaction, the federal government has gotten serious about cleaning up PFAS, a class of compounds known as “forever chemicals” that have been linked to health problems and inhabit the bloodstream of nearly every American.
Mounting public concerns and new state regulations in the U.S. are compelling water & wastewater utilities to address health risks associated with per- and polyfluoroalkyl substances (PFAS) – a class of pervasive chemicals found in drinking water and wastewater biproducts.
National Ground Water Association and others draft letter to EPA Administrator, urging science and research to be the leading factor in determining PFAS regulations.
University at Buffalo chemists have shown that self-assembling molecular traps can be used to capture PFAS — dangerous pollutants that have contaminated drinking water supplies around the world.
The traps are made from iron-based and organic building blocks that connect, like Legos, to form a tetrahedral cage. Experiments showed that these structures bind to certain PFAS (short for per- and polyfluoroalkyl substances), and a lab analysis revealed how this happens. As it turns out, the PFAS stick strongly to the outside of the cages instead of getting caught inside, researchers say.
Staring down a $3 billion — and growing — tab to clean up water sources at military installations across the country that are contaminated with cancer-causing chemicals linked to firefighting foam, the Defense Department is now in discussions with private firms about potential cleanup solutions that might reduce the cost.
