Lovely home near oil refinery.

First time home, everything I'd want for the price is in this house, I'm not in a rush, but the price, area, proximity to town is amazing. When I talked to the neighbor during the tour, he mentioned how close an oil refinery is, and how many people he know have gotten some form of cancer. The property is .3 miles away, to the northeast. Ive been trying to see what prevailing /common wind direction has been in the area, but have had no luck. Is this a red flag? It's a small refinery.
