Map: Detroit Garden Soil Sample Tests 2004-2016


Keep Growing Detroit offers soil tests to its network of gardeners (Garden Resource Program) and has since collected quite a large dataset of soil samples specifically looking for lead in the soil. The soil samples are obviously taken in sites where people are active and so high lead tests match fairly well with areas that have high childhood lead exposures. The areas with the darkest red test results also appear to match historic industrial sites in Detroit where soils may be forever contaminated.
