Been several years since I last dealt with this company* for water treatment systems so I can not vouch for them now but it might be worth looking into if you need to treat your water. They used to have very good service. BTW I noticed you mentioned offering either the listing price or higher for the land. Seems odd to me to offer more than what is asked.It's got iron and sulphur but tastes excellent after treatment.
Edit - I have a friend that lives within a mile as the crow fly's and I'm currently within 5 miles of it.
