I'm looking at putting in a lawn irrigation well. Unfortunately, the
two choices appear to be a relatively shallow well at about 50 ft,
which runs at least a 50% chance of containing too much iron, or a
500ft well which has only a 5% chance of having an iron problem. In
case you're not familiar with the iron issue, it creates brown side
walks or staining any place it gets on the house, etc. Looks like the
shallow well would be about $4K, while the deep one would be $12-15K.

With the shallow well, one option is a system that either filters out
the iron or treats it so that it will not create this problem. I'd
be interested in any actual experience others have to share on this,
ie what system they have, how much it cost to install, how much it
costs to operate, service, how well it works, etc. Also, keep in mind
this is an irrigation well, which will need to be capable of 28,000
gallons a week, so I'm not talking about a typical home water system.

I think you have answered your question. I speak as one who was responsible
for ensuring that folk on a public potable supply didn't get iron in their
water. Accepting a source that had a high iron content means treatment that
costs and is not guaranteed to work consistently. The extra $10k seems the
right choice to me.
