USA Today's story about lead factory contamination in nearby yards is a good example of CAR reporting.
They looked at records of soil tests and documents of hazardous contamination. USA Today also did their own soil testing of 21 neighborhoods. They used a 2007 report by the EPA to show the lack of response to previous concerns of contamination.
The reporter used analysis of these reports and data to determine they needed to do their own examination of the quality of government assessments.
They needed computer skills to a) find the documents and reports b) compute their own data. They needed basic searching skills along with more technical skills for testing.
