What is New at EPA? FOR IMMEDIATE RELEASEMay 9, 2012 EPA Promotes Safer Alternatives to Nonylphenol Ethoxylates WASHINGTON — The U.S. Environmental Protection Agency has released the final report on alternatives to nonylphenol ethoxylates (NPE) through the Design for the Environment (DfE) Alternatives Assessment Program. NPEs are widely used surfactants with a range of industrial applications and are commonly found in consumer products, such as laundry detergents. When released into the environment, they can be persistent and highly toxic to aquatic organisms. The report identifies eight safer alternatives to NPE that meet EPA’s criteria for safer surfactants. More information on the DfE Alternatives Assessment Program and the NPEs Report:http://www.epa.gov/dfe/pubs/projects/npe/index.htm

Why do I have to take that sample every month when the result has not changed in 10 years? Develop Your “If Only I Could…” List
