In urban planning, brownfield land is any previously developed land that is not currently in use that may be potentially contaminated. The term is also used to describe land previously used for industrial or commercial purposes with known or suspected pollution including soil contamination due to hazardous waste.
Generally, brownfield sites exist in a city's or town's industrial section, on locations with abandoned factories or commercial buildings, or other previously polluting operations like steel mills, refineries or landfills. Small brownfields also may be found in older residential neighborhoods, as for example dry cleaning establishments or gas stations produced high levels of subsurface contaminants.
Typical contaminants found on contaminated brownfield land include hydrocarbon spillages, solvents, pesticides, heavy metals such as lead (e.g., paints), tributyl tins, and asbestos. Old maps may assist in identifying areas to be tested.
