Their main point is wrong... but it is worth pointing out that a lot of the soils in the northest _do_ need to be tested not because of industrial pollution but because of agricultural pollution.

Apple orchards in particular up until the 70s often used lead arsenate pesticide sprays. Yes, you read that right; lead and arsenic. Sprayed onto plants. It accumulated in the soil and basically never leaves, and is a serious potential health hazard.

There has been insufficient discussion of this, overall, and it's basically "buyer beware" for land.
