Dry but periodic flooding = periodic mold

My garden level apartment floods every time we get rain for an extended period or heavily. It comes up through the foundation. I keep my apartment as dry as possible – to the point where my skin is very dry. I do everything possible – to the point where I stay home waiting with my shop vac and mop if I know a rainstorm or major snowmelt is coming. I clean things up as the water comes in. But a few times a year, I still get sick and smell mold. What can I do (other than move, because I’m stuck here) to make it less bad? Landlord already ripped up some laminate so I have all tile now thankfully. Any suggestions have to be safe around a cat.
