PROBLEM TO BE SOLVED: To provide a method for treating fluorine polluted soil which does not require secondary treatment of water etc. used for washing, permits construction on an original site without accompanying excavation and prevents the elution of fluorine easily and properly. SOLUTION: In the method for treating fluorine polluted soil, a calcium component and a phosphate component are allowed to exist in the state dissociated to each other in fluorine-containing soil and, thereafter, both components are chemically combined with each other to form calcium fluoroapatite.
