NTL now offers onsite testing equipment and supplies, including the Aquaking, a colorimeter preprogrammed to run up to 60 contaminants such as iron, manganese, nitrate, hardness, tannins and chlorine. Reagents are uniquely delivered in the vials used to collect your sample so there is no messing with powdered reagents.
The interest in reducing environmental lead exposure is evident with the recent revision by the U.S. Environmental Protection Agency (EPA) for the nation’s Air Quality Standards, which were lowered from 1.5 to 0.15 ug of lead per cubic meter of air. “With these stronger standards, a new generation of Americans is protected from harmful lead emissions, especially children,” said EPA Administrator Stephen L. Johnson. The same goal was desired for the drinking water lead standard, which the EPA lowered in 1998 from 50 to 15 µg of lead per liter of water.
Elevated levels of lead in drinking water occur despite government action
The SA-1000 scanning analyzer provides schools, municipalities and health departments with an easy-to-use, accurate test for lead and copper in potable water. Using a U.S. EPA- approved testing method, the SA-1000 tests for results as low as 5 ppb for lead analysis. Results are obtained in three minutes and data is stored for review or to upload to a PC.
A recent third-party study by Minnesota-based Water Science & Marketing (WSM), LLC, identified commercially available point-of-use (POU) treatment devices as effective for removing perfluorochemicals (PFCs) from drinking water supplies. Stephanie Harris, managing editor of Water Quality Products, recently spoke Phil Olsen, partner and project manager for WSM, about the findings of this study.
