The BAF 565 Series chemical-free filter removes iron, manganese and hydrogen sulfide while using up to 50% less water than traditional iron filters. Natural oxidation removes iron without the need for chemicals, air pumps or veturis. The 95 Series also is available for high flow rates for large residential and commercial applications. Both series are available in three models: BAF for neutral or higher pH, BIF for pH of greather than 7, and BIF MN for pH between 6 and 6.9.
Concentrations of cadmium, lead and zinc have been significantly reduced since cleanup activities began in the 1990s
A new report published by the U.S. Geological Survey (USGS) shows that U.S. Environmental Protection Agency (EPA)-led efforts to clean up historical mining contamination in the Coeur d’Alene and Spokane river basins in Idaho are improving water quality. Concentrations of three trace metals of concern—cadmium, lead and zinc—have been significantly reduced since cleanup activities began in the 1990s.
This patent-pending POU water filtration device produces drinking water without frequent maintenance, chemical additions or component replacement. The system traps and neutralizes contaminants through an ion exchange process. It processes enough water to support a family of six, includes built-in safe water storage and lasts for 10 years. The system meets the World Health Organization’s Household Water Treatment specifications for removing bacteria, protozoa and viruses.
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).
