About 200 million Americans, nearly two-thirds of the population, drink water containing fluoride to fight tooth decay. That could be changed by a case now on trial in a San Francisco federal court.
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.
As California navigates a critically dry water year, many business-as-usual elements are getting a second look. One such transaction is a proposed water sale by the Merced Irrigation District.
House Democrats plan to release a massive green infrastructure package this week, an aide confirmed to E&E News, ending months of anticipation among transportation and infrastructure advocates.
The long-awaited package, which would include reauthorization of expiring surface transportation provisions, is expected to resemble a framework unveiled in January (Greenwire, Jan. 29).
“Text of the surface bill will be released in the coming days,” a House Democratic aide said in an email to E&E News yesterday. “Like the framework House Democrats released earlier this year, it’s expected a number of items will address climate change and safety, which are focal points.”
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.
The nation’s water utilities, facing more than $27 billion in lost revenue from the pandemic, are ramping up their outreach to Congress as lawmakers prepare to act on infrastructure legislation and additional relief in the face of a historic pandemic.
In addition to a flurry of letters and meetings, advocacy groups and lobbyists with congressional expertise are pushing for provisions in both Water Resources Development Act bills moving through the House and Senate, and the next round of COVID-19 stimulus funds.
In the near term, the bills could be a lifeline for both residents and utilities reeling from the economic fallout of the pandemic.
Over the longer term, some hope the bills could provide a pathway for revamping a highly fractured, aging water system — old lead pipes, vulnerable dams and 1,500 drinking water systems in violation of the Safe Drinking Water Act, said Robert Powelson, CEO of the National Association of Water Companies.
SACRAMENTO — Fewer rebates for electric-car buyers. No new oil and gas industry regulators. Less money to preserve wildlife habitats.
Gov. Gavin Newsom’s proposed spending cuts to balance a state budget mauled by the coronavirus pandemic have angered numerous progressive constituencies, but perhaps none more than environmental activists who were suspicious of him even before an estimated $54 billion deficit materialized.
Before San Francisco office workers start streaming back to downtown high-rises again, property owners and managers need to make sure those buildings are safe. Not just from the threat of coronavirus circulating among cubicles, but from medical problems that can be caused when water in buildings sits stagnant for months.
If you have a small, drinking water system in the Central Valley that’s full of nitrates, and there are plenty, a company has some bugs to sell you. Specifically, a company called Microvi is looking for a demonstration project in the valley to show that its “biological denitrification” process is feasible for small systems.
The EPA won’t be able to set drinking water limits for two PFAS chemicals in the next year, agency administrator Andrew Wheeler told the Senate Environment and Public Works Committee Wednesday.
The Environmental Protection Agency determined that it’ll set maximum contaminant levels (MCL) for the two chemicals—PFOA and PFOS—in drinking water, but hasn’t proposed what those limits should be.
