Gary, I appreciate all of the advice and suggestions. I don't appreciate the ridicule when I do a ton of research and follow the same methods advised by state health department literature, local well drillers, forum experts and so on. There is more than one way of dealing with this problem. Other than my very first treatment (with puck), I have treated everything just as suggested (with liquid) but I have not been able to squeeze in follow up treatments. The iron totally disappears for 6 weeks or so after a small chlorination of 6% bleach. 95% of the "experts" have told me try this first. I know that this forum takes time for everyone. Speedbump spends alot of his time tearing down others methods. A good transfer of Q & A is healthy for anyone who will read this in the future and incurs similar problems. Maybe they can benefit from my mistakes or success.
Ridicule.... I don't recall seeing any but maybe you mean corrections to your assumptions.
The health department gets its info from universities and other governmental agencies and combined they usually simply repeat the same decades old message (while supporting the use of chlorine) but... they usually don't know what they are doing because no one there has ever had any hands on experience, just book larnin' if ya know what I mean, IOWs they're dummer'nhell.
Sorry to disagree with you again but... There is only one RIGHT way to deal with any problem, including your water quality problem. And you haven't listened to me yet, and I do water treatment right the first time and usually at the lowest cost of anyone...
You are dealing with IRB, they live in the ground above and under the water table; aerobic and anaerobic (need or don't need air to live). Your shocking the well is killing those within reach of the bleach only and are replaced as soon as you use the smallest amount of water. It is a band aid at best and can cause serious damage to the pump, power cable, drop pipe if metal and metal fittings AND cause nontreatable water quality problems AND a reduction in water production of the well requiring well cleaning and rehabilitation.
Now did you read about any of that at any government site, or from well drillers that live off drilling new wells or working on old bad wells, or any 'forum experts' that only are 'cuz they own or have owned or wouldn't want to own a well? I think not except for Speedbump and I....
Now you want to inject bleach through and into your steel well casing to dribble or run down the inside of it.... chlorine eats steel very quickly, within days, trust me on that. Note Speedbump's caution too.
And you can't drill a new well on your property!
That's because you don't have a way to get a drilling rig in. See now I would have thought about that before building any building to prevent a drilling rig or derrick truck to my ONE'N ONLY ever WELL!!
Since that is the case, you best treat that well and its casing as if it was Fort Knox because the future value of the ENTIRE property depends on it.
Property like a house with no water is worthless. The same goes for a property with useless water. You know I'm right. So get rid of the attitude and stop all assumptions or run a high risk of really screwing up your future. It's your choice to get over your hurt feelings or not.
I have equipment that will kill the bacteria, stop any odor and oxidize iron, H2S and any manganese and then filter out the chlorine and rust/dirt delivered anywhere in the lower 48 for less than $1750.00. That is with an automatically backwashed filter large enough for a 2.5 to 3 bathroom house. You may not need that size filter and then the price would be less. I have sold that system for 15 years and since Sept 2003, roughly 50 of them to DIYers online. But you don't have to buy from me, there are a lot of online and local dealers, but you better listen to me and others here and buy something instead of using bleach in your well consistently and damaging it permanently because it's the only well your house will ever have.
