Information　about　the　concentrations　of　strontium　(Sr(II))　in　drinking　water　in　China　and　the　corresponding　health　risks　to　Chinese　residents　is　lacking.　This　study　investigated　Sr(II)　in　drinking　water　through　a　monthly　sampling　campaign　in　twelve　locations　in　Xi＇an,　Northwest　China.　A　health　risk　assessment　for　different　age　groups　and　exposure　pathways　were　carried　out　by　Monte　Carlo　simulation.　The　results　show　Sr(II)　concentrations　of　0.06-1.69 mg/L　in　all　drinking　water　samples,　which　exceeded　the　minimum　reporting　level　(MRL)　of　0.3 μg/L.　Also,　one　sample　exceeded　the　health　reference　level　(HRL)　of　1500 μg/L.　Higher　Sr(II)　levels　were　recorded　in　groundwater　supply　zones　and　springs,　and　more　potential　changes　in　Sr(II)　occurred　in　distribution　pipes　transporting　groundwater.　The　non-carcinogenic　risk　associated　with　Sr(II)　exposure　via　drinking　water　was　less　than　1,　indicating　no　significant　health　risk　to　the　residents　of　Xi＇an.　As　the　first　attempt　to　provide　information　on　the　health　risks　of　Sr(II)　in　drinking　water　in　China,　findings　from　this　study　can　be　useful　for　the　development　of　potential　strategies　for　risk　control　and　management.
