Using new observations from the Virgo Environment traced in CO survey (VERTICO) and archival H I data, we study the H I and molecular gas within the optical discs of Virgo cluster galaxies on 1.2-kpc scales with spatially resolved scaling relations between stellar (S-*), H I (S-H I), and molecular gas (S-mol) surface densities. Adopting H I deficiency as a measure of environmental impact, we find evidence that, in addition to removing the H I at large radii, the cluster processes also lower the average S-H I of the remaining gas even in the central 1.2 kpc.
