Your assumption about concentric circles is correct, and the nodes do ignore land as an obstacle. Personally? The trouble's only worth it if you think there's at least q30+ water there.
However, well points are exactly a dime a dozen. You probably won't have one right on the node center, but if the node is inland from the rivers the quality should go up nicely.
I did find q30+, but I thought I should be able to know what q is under my well precisely.
