Aluminum may affect lead levels in drinking water

Researchers find aluminum in water could affect lead’s solubility — in certain cases

It is not uncommon to find aluminum in municipal water systems. It’s part of a treatment chemical used in some water treatment processes. Recently, however, it has been discovered in lead scale, deposits that form on lead water pipes.

The aluminum presence in pipes is both unsurprising and, in the quantities researchers saw in water pipes, not … [more…]

Nanocellulose used to remove microplastics from water

Nanocellulose used to remove microplastics from water

While no one likes seeing plastic waste floating in our waterways, tiny unseen "microplastic" particles are also a threat to the aquatic environment – and to human health. A new study now suggests that a material known as nanocellulose could be used to remove them from … [more…]

Researchers identify new toxic byproducts of disinfecting drinking water

What's in your water? Researchers identify new toxic byproducts of disinfecting drinking water

Mixing drinking water with chlorine, the United States’ most common method of disinfecting drinking water, creates previously unidentified toxic byproducts, says Carsten Prasse from Johns Hopkins University and his collaborators from the University of California, Berkeley and Switzerland.

The researchers’ findings were published … [more…]

Scientists: new way to get ‘forever chemicals’ linked to cancer out of our water

Scientists found a new way to get 'forever chemicals' linked to cancer out of our water. They're in the bloodstreams of 99% of Americans.

They’re in the bloodstreams of 99% of Americans.

  • Researchers at Clarkson University are working with the US Air Force to remove a group of "forever chemicals" from water.
  • The chemicals, known as PFAS, have been associated with cancer, liver damage, and developmental issues.
  • They’re found in food packaging, cookware, outdoor gear, and firefighting

PFOS & PFOA: Air Force researchers develop new weapon to cleanse water

Air Force researchers develop new weapon to cleanse water

As the state gears up for wider testing of public water systems for potentially harmful chemicals, civilian researchers at Wright-Patterson Air Force Base believe they may be closing in on a new weapon in the battle against toxic water.

Researchers at the base recently completed a two-week field demonstration of a plasma technology they say destroys potentially harmful chemicals perfluorooctane sulfonate and perfluorooctanoic acid — also known as “PFOS” and … [more…]
