EPA has recognized Underwriters Laboratories as a provider of the services needed to comply with new water regulations
Water quality and water safety company Underwriters Laboratories Inc. (UL) recently announced that it has become one of the first organizations approved by the U.S. Environmental Protection Agency (EPA) to test for 28 contaminants in EPA’s third Unregulated Contaminant Monitoring Rule (UCMR 3).
The DR6000 advanced lab spectrophotometer offers high-speed wavelength scanning across the UV and visible spectrum, and comes with more than 250 pre-programmed methods that include the most common testing methods used today. With optional accessories allowing for high-volume testing via a carousel sample changer and increased accuracy with a sample delivery system that eliminates optical difference errors, this instrument ensures readiness to handle wide-ranging water testing needs.
The International Accreditation Service is recognizing June 9 as World Accreditation Day
The International Code Council’s subsidiary, International Accreditation Service (IAS), is recognizing June 9 as World Accreditation Day and promoting the theme for the day: Accreditation-Supporting Safe Food and Clean Drinking Water.
More than 60 countries are participating in the global initiative established by the International Accreditation Forum (IAF) and the International Laboratory Accreditation Cooperation (ILAC).
Approved method for global bottled water safety
3M Food Safety announced May 21 that its Petrifilm Aqua Coliform Count Plate has received NF validation from France-based Assn. Francaise de Normalisation (AFNOR) for its ability to detect and enumerate colonies of E. coli and coliform bacteria in bottled water samples.
When considering reverse osmosis (RO) for water treatment, there are several things that should be taken into account. One of the most important things to consider is the quality of the water to be treated. RO is widely used to remove harmful inorganic contaminants; however, due to the limitations and higher operating cost, pretreatment of the water may be necessary. For example, hardness minerals are common in groundwater, and at high levels, pretreating with a softener is often recommended.
WQHC to offer free pH and chlorine test strips again this year
As Memorial Day approaches, heralding the summer pool season, a new survey on swimmer hygiene conducted by the Water Quality & Health Council (WQHC) finds that although most (93%) say they would never reuse someone else's bath water, almost seven in 10 (68%) admit they do not always shower before getting in the pool. Failing to shower before swimming adds contaminants to the pool that can lead to unhealthy swimming conditions.
Protecting public health by providing safe drinking water to citizens served by community water systems is and will always be a serious concern of government agencies, public water suppliers and private industry around the world. There is a growing need to make the onsite testing of these water supplies easier and more reliable to detect and assess contamination in a timely manner to shorten the harmful health effects of heavy metals in drinking water.
Detecting heavy metals in drinking water
The most common question from customers of water treatment systems utilizing adsorbent media is, “How long will the media/system perform?” The most common answer may be a number of months or years but should be more elaborative than a mere number. The most honest answer is, “It depends on the water chemistry.”
New test improves prediction of system and media performance
USGS analysis examined concentrations of chloride, dissolved solids and nitrate in groundwater
There was no change in concentrations of chloride, dissolved solids or nitrate in groundwater for more than 50% of well networks sampled in a new analysis by the U.S. Geological Survey (USGS) that compared samples from 1988 to 2000 to samples from 2001 to 2010. For those networks that did have a change, seven times more networks saw increases as opposed to decreases.
Newly published research paper demonstrates test inaccuracies due to sample holding time
Water management services company Phigenics LLC recently announced the publication of a research paper that demonstrates up to 33% false-positive test results for Legionella bacteria when following conventional sampling methods.
