Keeping Up With the Contaminants

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.

Iron Filter

Company Reference: 

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.

Packaged Treatment Systems

Company Reference: 

WaterPod containerized treatment units contain one of many AdEdge package units treating a wide variety of contaminants for drinking water, remediation or industrial applications. The fully integrated, pre-engineered, pre-wired packaged water treatment solution combines system performance with economy, resulting in a solution for sites where space, cost and schedule are critical.

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.

Filtration System

Company Reference: 

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.

Radiation & Water

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.

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.
