Can you put bleach in a well for sulfur?

Yes, you can use plain, unscented household bleach to disinfect a well and control sulfur odors, a process called "shock chlorination," by adding it to the well and flushing the system until the chlorine smell appears at all faucets, but you must use the right amount, follow safety precautions, and often need to treat the hot water heater too. This method kills sulfate-reducing bacteria that cause the rotten-egg smell but may need repeating, or a permanent chlorination system might be better for chronic issues.

What is the cheapest way to remove sulfur from well water?

Chlorine bleach can effectively remove medium to high levels (over 6 mg/l) of hydrogen sulfide. The chlorine in the bleach chemically reacts with (oxi- dizes) the hydrogen sulfide eliminating the "rotten egg" odor. Chlorine bleach also reacts with iron or manganese, and disinfects water supplies.

Sulfur, particularly hydrogen sulfide gas causing odors, is neutralized by oxidizers like chlorine or hydrogen peroxide, which convert it into solid, odorless sulfur; by aeration systems that strip the gas; by zinc-infused products (for breath); and in soil, by adding lime to raise pH, while diets can be managed by reducing high-sulfur foods and using digestive aids like probiotics or flaxseed.

Bleach struggles to kill bacteria that form tough protective endospores, like Clostridioides difficile (C. diff), and certain naturally chlorine-resistant types such as Bacillus, Mycobacterium, and Tsukamurella. Other survivors include H. pylori (which can actively swim toward bleach) and microbes protected by biofilms, with effectiveness also depending on contact time and solution strength.
