Program to serve as a model for similar programs across the country
Virginia’s approach to improving water quality in Chesapeake Bay gained recognition from several federal agencies, which dubbed it “an innovative, market-based approach” that will “serve as a model for similar programs across the country.”
A growing demand for potable water in the Asia Pacific region will transform the region’s residential water treatment equipment market
A new market research report on the residential water treatment equipment market in the Asia Pacific region by TechNavio reveals an expected growth at a compound annual growth rate (CAGR) of 15.53 percent from 2014-2019.
AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
Fifteen contaminants covered by standard include drugs, herbicides, pesticides and chemicals
EPA Awards Texas more than $2.5 million to reduce water contamination risk in underground tanks
The U.S. Environmental Protection Agency (EPA) recently awarded the Texas Commission on Environmental Quality $2,506,000 to prevent and respond to petroleum leaks from underground storage tanks (USTs).
Emerging contaminants and incidental compounds discovered in drinking water supplies have sparked consumer concern throughout the U.S. WQP Associate Editor Williette Nyanue spoke with NSF Intl. drinking water expert Richard Andrew to find out what consumers are saying and how the new NSF/ANSI Standard 401 will help address these concerns.

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.
