Radiological contamination of water is due to the presence of radionuclides, which are defined as atoms with unstable nuclei. In an effort to become more stable, a radionuclide emits energy in the form of rays or high-speed particles. This is called ionizing radiation because it displaces electrons, which creates ions. The three major types of ionizing radiation are alpha particles, beta particles and gamma rays.
Risks, testing & treatment of radionuclides in drinking water
A Ph.D. student's research may save lives
A "super detector" that can track the traces of a lump of sugar in the Baltic Sea was the starting point for a potentially life-saving technique developed at Lund University in Sweden. The method detects toxic algae blooms in drinking water.
A biosensor recently developed at Lund University can detect substances at 10,000 times lower concentrations than what is currently possible. PhD student Lesedi Lebogang found a practical application that could be particularly helpful in warm climates such as Africa, Australia and the southern U.S.
EPA meets with residents to find non-time critical cleanup alternatives for drinking water
The U.S. Environmental Protection Agency (EPA) held a public meeting to inform the public of the draft Engineering Evaluation and Cost Analysis (EE/CA) for the non-time critical cleanup alternatives for drinking water impacted by the Ore Knob Mine Superfund Site in Laurel Springs, Ashe County, N.C.
The meeting’s outcome will help EPA choose the best alternative to ensure residents living in the vicinity of the historical mining operations and flooded underground mine workings are protected from releases to groundwater at the Ore Knob Mine Site.
NSF Intl. survey findings reinforce the need for water quality standard
A vast majority (82%) of consumers report they are concerned about trace levels of emerging contaminants in drinking water, such as pesticides and herbicides (87%), prescription drugs (34%) and detergents (24%), according to a new survey from NSF Intl.
Research finds higher levels of infectious pathogens in water from faucet taps with aerators
New research has found significantly higher levels of infectious pathogens in water from faucet taps with aerators compared to water from deeper in the plumbing system, which Sweden's Bluewater believes underlines the need for additional research to discover how water contamination threatens patient health.
The nearly $12 million in funding will be made available to Ohio, Michigan and Indiana agencies, as well as some federal organizations
U.S. Environmental Protection Agency (EPA) Administrator Gina McCarthy announced that the Great Lakes Restoration Initiative (GLRI) will provide almost $12 million to federal and state agencies to protect public health by targeting harmful algal blooms (HABs) in western Lake Erie. The funding builds upon GLRI’s ongoing efforts to reduce algal blooms and will be made available to Ohio, Michigan and Indiana state agencies and to the U.S. Geological Survey, the U.S. Department of Agriculture Natural Resources Conservation Service and the National Oceanic and Atmospheric Administration.
NSF/ANSI 401: Drinking Water Treatment Units - Emerging Compounds/Incidental Contaminants addresses the ability of a water treatment device to remove up to 15 contaminants from drinking water
NSF Intl. has developed the first American National Standard that validates the effectiveness of water treatment devices that are designed to reduce trace levels of emerging contaminants in drinking water. The standard, named NSF/ANSI 401: Drinking Water Treatment Units - Emerging Compounds/Incidental Contaminants, addresses the ability of a water treatment device to remove up to 15 contaminants from drinking water. Types of contaminants include some pharmaceuticals, over-the-counter medications, herbicides, pesticides and chemicals used in manufacturing, such as bisphenol A (BPA).
Protecting the quality and safety of our nation’s drinking water is an important and never-ending task. NSF Intl., a global independent public health organization, works with government, industry and consumer groups to make sure harmful contaminants and chemicals are not added to drinking water.
New standards ensure protection against tampering & emerging contaminants
“Ensuring Safe Drinking Water” offers 21 case studies and in-depth analysis
The American Water Works Assn. (AWWA) released its newest publication, Ensuring Safe Drinking Water: Learning From Frontline Experience With Contamination by Steve E. Hrudey and Elizabeth J. Hrudey.
The forum is a response to the microcystin contamination in Toledo, Ohio
In response to the microcystin contamination in Toledo, Ohio, the Water Quality Assn. (WQA) Water Sciences Committee is hosting an online meeting/conference call to share information and have a technical discussion regarding this event.
