Not a problem to treat. The iron and pH are the main issues. Left untreated this will be nasty. You have many options but are you planning on DIY or having a local company deal with it? Do you have copper, pex, cpvc, or ? plumbing in the house?
pH neutralization and it is likely you will need to raise it above 7.5-8.0 to correct for LSi issues.
Simple neutralization, oxidant injection, contact tank, and iron reduction/ either manganese dioxide ore based media or GAC/clinptilolite blend may work.
1st big question - would this make you walk away from a house you really liked?
2nd big question - can you provide a quote with parts to fix the pH and iron issues, just a quote for materials?
I have no problem going the DIY route, but we have dealt with a local company that we feel good about and they use Water Rights products.
The house has polybutylene throughout, and the pressure tank is water logged.
Also, the house was built in 1989, sold in 2008 and has been vacant since 2008 aside from renters for 18 months.
Is it possible it will clear up if we replace the pressure tank and use it normally - could the water just be stagnat?
Appreciate all your help!
