The Compact turbimeter tests for turbidity and TSS in drinking water, wastewater and surface water. It provides accurate readings of samples with settling matter and features continuous measurement, averaging and suspended solids operating modes. It has a resolution of 0.01 ntu and a dynamic range of 0 to 1050 ntu with results available in other units. Results are logged and tagged with operator and site identity information.
The eXact Micro 20 dual-wavelength photometer features quality design and engineering with the latest patented technologies to deliver sustainable water testing solutions that cost less. It is waterproof (IP-67) and quickly performs onsite testing for more than 30 direct-read water quality parameters without look-up tables. It features a narrow-band wavelength filter for optimal accuracy, long-life LEDs and a built-in cell for ultra performance. Each parameter stores the 20 previous results for a total of more than 600.
Conforlab of Brazil signs on as Phigenics LLC first licensing partner
Phigenics LLC has launched a licensing practice for its patented Legionella testing technology. Conforlab Engenharia Ambiental LTDA of Sao Paulo signed on as the first licensee in December 2012.
Update includes setting a limit for E. coli to better protect public health
The U.S. Environmental Protection Agency (EPA) has updated the rule for pathogens in drinking water, including setting a limit for E. coli to better protect public health.
The Revised Total Coliform Rule ensures that all of the approximately 155,000 public water systems in the U.S., which provide drinking water to more than 310 million people, take steps to prevent exposure to pathogens like E. coli. These types of pathogens can cause a variety of illnesses, with symptoms such as acute abdominal discomfort or, in more extreme cases, kidney failure or hepatitis.
The ColorQ DW is a handheld photo-meter kit for onsite drinking water testing. It digitally measures seven factors: hardness, pH, iron, nitrate, free chlorine, total chlorine and sulfide. The large digital display eliminates the guesswork with traditional visual color-matching methods. A sturdy case contains the meter, test solutions and instructions.
UL will provide testing services for public water systems serving fewer than 10,000 people
Underwriters Laboratories Inc. (UL) has won a contract from the U.S. Environmental Protection Agency (EPA) to test samples from small public water systems serving 10,000 people or fewer for contaminants listed in the third cycle of EPA's Unregulated Contaminant Monitoring Rule (UCMR 3) program.
Groundwater provides a valuable source of drinking water for millions of people across the U.S. But as new contaminants are discovered and droughts continue to worsen, resulting in depleted aquifers, it is increasingly important to monitor the quantity and quality of available groundwater. The U.S. Geological Survey (USGS) recently updated Water Quality Products on the status of groundwater quality in the U.S.
What is the role of the USGS in surveying and monitoring groundwater quality and availability in the U.S.?
U.S. groundwater faces increasing contamination & overuse
The PT2 pH and temperature pen is designed to be extremely accurate, fast and simple to use in diverse water quality applications. Advanced features include temperature compensation; one-, two- and three-point calibration; choice of continuous and snapshot measurement modes; and waterproof housing. A true one-handed instrument, it is easy to calibrate and use. To take a measurement, simply push a button, then dip in solution.
Water treatment has evolved greatly over the past several years, from simple filters and water softeners to more complex treatment including new and different media, reverse osmosis, ultrafiltration and nanofiltration. A major reason behind this move forward is that more water testing is being done throughout the U.S. by public water systems, in addition to studies by the U.S. Geological Survey that map common contaminants in groundwater and surface waters such as lakes and streams.
