The plot thickens and there is definitely an odour involved as well. My findings are not yet definitive however something is wrong.  What has me concerned? Well for starters asphalt highways on hot days emit fumes. Bad fumes. Volatile Organic compounds as well as Polycyclic Aromatic Hydrocarbons (PAHs) are emitted. Apparently coal tar based roads (Macadm) emit higher concentrations. But that's the rub. How many tarmacadam or just plain macadam roads or highways have you been on lately? Exactly. 

So why are our authorities removing subsurface coal tar (macadm) based roadways such as beneath Church St. East in Elmira? It would seem to me that whatever the concentration of various chemicals are that they are more likely to be emitted when exposed to sunshine and heat. Is the removal of old, buried coal tar roads or chunks thereof simply virtue signaling? I will await further communication from both the Region of Waterloo and the Ministry of Environment and hope that they can shed some light on this matter.
