Environmental Protection Agency (EPA). 2011. Brownfields and Urban Agriculture: Interim Guidelines for Safe Gardening Practices. Accessed at: http://www.epa.gov/sites/production/files/2015-09/documents/bf_urban_ag.pdf
This guidebook is a result of input from 60 experts in 2010 who gathered in Chicago to discuss “the range of issues which need to be addressed in order to safely grow food on former brownfield sites”. In other words, when talking about environmental contamination, how clean is clean relating to food production in urban areas. Three major issues came out of the discussion and are covered in this resource. They are: the history and past uses of the site in question, options for testing and cleaning up the site so one can garden safely, and the gap between clean up standards regarding health safety and the often lacking consumption health standards.
