Keep soaking that foot until you can pop the top off easily and then squeeze it, rinse it, squeeze it some more until you get all of that nastiness out of there. Pack it with triple antibiotic (without pain killer, the sort that has the consistency of vaseline), put a teflon non-stick gauze over the wound, and wrap in sports tape to make a little bootie for her. The gauze will get wet when she swims, but the sports tape should be fine. Change the dressing daily and examine for swelling or persistent infection.
