A recent report from the Environmental Working Group revealed the presence of hexavalent chromium in the tap water of 31 of 35 cities. Norman, Okla., had the highest level of all the cities tested. Water Quality Products (WQP) spoke with Dr. Robert Nairn of the University of Oklahoma (OU) to learn more about chromium-6.

University of Michigan to co-sponsor studies focusing on gold mining in Ghana and stomach cancer in Peru
The University of Michigan's Graham Sustainability Institute and the Center for Global Health are co-sponsoring two research projects addressing water quality impacts on public health, one in Ghana and the other in Peru.
Each of the projects, which are called integrated assessments, will receive $350,000 over the next three years.
Catalyst Energy Inc. must pay fines, take corrective actions at well sites
The Pennsylvania Department of Environmental Protection (DEP) today announced it has fined Catalyst Energy Inc. $185,000 for a number of violations at its non-Marcellus oil and gas well operations in Forest, McKean and Warren counties.
In addition to paying a fine and taking corrective actions at its well sites, Catalyst faces restrictions on drilling, hydraulic fracturing and developing new or existing well sites.
Patented KDF 55 process medium provides a highly effective means of removing contaminants in water in POE or POU applications, removing up to 99% of heavy metals from filtered water. KDF 55 medium is a high-purity formulation of copper-zinc alloy that reduces contaminants such as chlorine, bacteria and heavy metals using a chemical process called redox, or oxidation-reduction.
The Centurion filtration system uses Isobar II controls for forward and reverse motor capability, and can replenish its oxygen chamber without having to backwash, saving hundreds of gallons of water each week. Fully adjustable cycles and Vortech tank technology ensure that the media bed is backwashed to the fullest extent, removing iron or sulfur contaminants from the water.
Otis is located in Berkshire County, Mass., and has a population of 572, according to the 2000 U.S. Census Bureau data. The town is surrounded by several lakes and ponds. Berkshire County, located in the western part of the state, was founded in the early 18th century, prior to American independence. The Berkshires, as the general region is referred to, are the southern continuation of the Green Mountains, which are located directly to the north in Vermont.
Microbial reduction filtration system provides clean water for summer home in The Berkshires
LayneRT is a hydrous iron oxide impregnated resin that efficiently binds arsenic and never needs backwashing. It is engineered in a single-column design to treat a full cold-water flow so no special low-flow faucet is needed. The POU system provides simple installation and comfortably fits under most sinks. Because system performance is tied to site-specific water chemistry, SolmeteXWater has integrated a comprehensive sampling program into the npXtra system to ensure continued performance. Chemists regularly analyze your customer’s water quality by sending them pre-paid sample kits.
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 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.
