IDAHO FALLS, Idaho (AP) – Officials with the U.S. Department of Energy say the Idaho National Laboratory has developed an economical technique for removing arsenic from water supplies that is seven times more effective than anything currently available.

In a statement Friday the agency also says a licensing agreement that gives exclusive rights to market the technique has been signed with Water Technology Group Inc., based in Harvard, Mass.

The Environmental Protection Agency has set the maximum safe arsenic level for drinking water at 10 parts per billion, down from 50 parts per billion previously allowed, and that became effective in January 2006.

Some studies show arsenic in drinking water at levels greater than 10 parts per billion can increase rates of some cancers.
