There are numerous sites in Arizona where the soil and groundwater have been contaminated by improper disposal of contaminants. To check if a property is in an area designated by the ADEQ as requiring cleanup, see www.adeq.state.az.us/environ/waste/sps/phx.html for available maps to view. The EPA also has information on Federal sites at www.epa.gov/superfund/spanish/index.htm (Spanish).
