I had posted earlier this year about sulfur problems with a recently drilled well. We are now without water due to the sulfur contamination and desperately looking for help / advice.
Here's what we've done:
July 2011 - New home, city water not available, well drilled, ran for 3 days out of a water hose. Sulfur smell strong.
August 2011 - Water tested at 10+ ppm sulfur.
January 2012 - After saving for months and building a small climate controlled addition to our new home, a peroxide injection, carbon filter, softener system was installed. Sulfur PPM less than 0.5. Day 3 sulfur smell returns, Day 4 water is grey and sulfur is at 6 PPM.
After doing some research, we found out the pressure tank was in the wrong order:
Well - Peroxide Inj - Carbon - Softener - Pressure Tank - House
We switched the pressure tank to after the peroxide injection point. Added new carbon and after 3 - 4 days had the same results as before. I made sure it was injecting peroxide and had the pump on 5. It was backwashing every 24 hours. I backwashed the system 4 times in one day with the peroxide pump maxed out at 10. The best I could get was 4 PPM sulfur at the tap.
I tested it at the well and it was maxed out on my test kit, which goes to 20 ppm.
Any suggestions? Is 20+ PPM just too much to filter out? I'm out of cash and out of ideas... Any advice is greatly appreciated!
