NAPERVILLE, IL – Nalco has responded to the Environmental Protection Agency’s (EPA) release of test results that studied dispersants used to fight the oil spill in the Gulf of Mexico. In announcing the results, an EPA representative said that the EPA is not recommending any change in dispersants used to fight the spill.

"We are pleased that the EPA's initial testing results of dispersant alternatives continue to show the safety of our COREXIT 9500 dispersants," said David Horsup, Division Vice President, Research and Development for Nalco's Energy Services division.

The agency's press release said all the dispersants it tested, including COREXIT 9500, "have roughly the same impact on aquatic life.” Additionally, it stated that none of the dispersants tested displayed biologically significant endocrine-disrupting activity. In fish species tests, COREXIT 9500 was identified by the EPA as one of two products included in the safest category. The EPA also stated that dispersants biodegrade, have not been found in the water column and have not settled on the floor of the gulf.
