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.
New wells will provide early alerts for groundwater contamination
Scientists from the U.S. Geological Survey (USGS) began drilling “sentinel” wells at the first of three locations in the Trumbull Village neighborhood in Albuquerque, N.M., to provide early alerts for groundwater contamination.
These new sentinel wells will provide early warning if there is a northeastward movement of the Kirtland Air Force Base Bulk Fuels Facility plume, and would provide Albuquerque Bernalillo County Water Utility Authority (ABCWUA) and Air Force officials lead time to implement plans to protect nearby groundwater drinking water supply wells.
EPA decides no further action needed to address the capping of two closed landfills
The U.S. Environmental Protection Agency (EPA) has finalized its determination that no further action is needed to address the capping of two closed landfills at the Cinnaminson Groundwater Contamination Superfund site in the townships of Cinnaminson and Delran, N.J. The site, which covers approximately 400 acres, includes residential and industrial properties and the two landfills.
New USGS modeling report describes chloride movement in the area's aquifer
Chloride contamination of Wichita, Kan.’s, water supply wells is inevitable unless actions are taken, according to U.S. Geological Survey (USGS) scientists and authors of a new modeling report describing chloride movement in the area's aquifer.
There are many different technologies that can be used to reduce the level of contaminants in water. The two most common that are tested in the Water Quality Assn.’s (WQA) product testing laboratory are reverse osmosis (RO) systems and filters. This testing is used to provide independent third-party certification for these types of products.

The process for certifying POU & POE devices to NSF standards
In 2011, the Water Quality Assn. (WQA) reported in Water Quality Products on the history of lead in drinking water and the difficulties of testing for it.

Duke Energy takes full responsibility for the Dan River incident
Duke Energy's North Carolina state president, Paul Newton, spoke before the N.C. Joint Environmental Review Commission (ERC) on the company's response to the Feb. 2 Dan River coal ash incident and its near-term and longer-term actions to address coal ash across the state.
Newton told the ERC the company takes full responsibility for the Dan River incident. He also discussed the significant steps Duke Energy has taken on the site and in the river since the company's previous update to the ERC on Feb. 17. These include:
