US to curb 'rocket-fuel chemical' in water
The US will clean up its act by setting tougher limits on levels of perchlorate in drinking water.
In a decision that reverses a 2008 policy of the Bush administration, the Environmental Protection Agency announced last week that it will regulate more strictly the permissible levels of perchlorate – a natural chemical which is also synthesised for use in rocket fuel, bleach and fertilisers. If ingested at high levels the chemical may disrupt the thyroid's ability to produce hormones that are critical to development.
The EPA says the chemical contaminates the drinking water of between 5 and 17 million Americans in 26 states. A 2009 study by the Centers for Disease Control and Prevention found that it was also present in 15 brands of powdered infant-formula.
