+To approach the Chandasekhar mass and explode as a Type Ia supernova, a white    
+dwarf must accrete material from a binary companion. In most cases, this        
+transfer of material should leave an imprint on the environment in the form of  
+detectable circumbinary material. I will discuss multi-wavelength constraints on
+the environments of SNe Ia and the implications for progenitor systems, with    
+particular focus on our deep radio observations with the JVLA.
