  6. Science Topics to be addressed byALFALFA: 1 The investigation of the HI Mass Function 2 High Mass HI sources 3 Environmental variations of the HI properties of galaxies 4 The low HI Column density environment of galaxies 5 Environmental differences in the HI Mass function 6 HI absorbers and the link to Lyman a absorbers 7 OH Megamasers at intermediate redshift
