The Soil Safety Resource Guide for Urban Food Growers out of the John Hopkins Center for a Livable Future discusses how growers can reduce the risk of soil contaminants on plots of land within urban areas. Specifically the publication discusses contaminants such as lead, petroleum products, and asbestos, and how people may come into contact with these contaminants. “Farmers and gardeners can be alerted to the presence of contaminants by testing their soil and investigating prior uses of their land. Contact with potential contaminants can be minimized by following best practices, such as locating plots away from busy roads, thoroughly washing produce, and peeling root vegetables. While risk exists no matter where our food comes from, these precautions can keep soil contaminant risks to a minimum”.
