An investigation by the Government Accountability Office found that during the Bush administration the White House was delaying the EPA’s efforts to assess whether chemicals posed a public health risk. The agency said it needed to complete 50 assessments a year to do its job properly. Instead, it averaged five a year. The Obama administration promised to fix this. But in the past three years, it has completed fewer assessments of chemicals than at any time in the EPA’s history.
