Osorno's well treatment chemicals remove scaling, iron deposits, and persistent bacteria (iron bacteria or bacteria hidden in biofilms).

Osorno's well treatment chemicals are much more efficient and safer than commonly used methods such as concentrated acid (also known as hydrochloric or "muriatic" acid) or shock chlorination.

Osorno discourages the use of concentrated acid because:

• The user can easily inhale its fumes, posing a significant health risk;
• It is highly corrosive, even with stainless steel;
• In wells, it can react with deposits of manganese oxide to form chlorine gas.

Osorno discourages shock chlorination because:

• It produces chlorinated organic compounds that persist in the environment, which can harm living beings as many of these compounds are carcinogenic;
• The high pH of hypochlorite solution ("bleach", "liquid chlorine") causes precipitation of calcium ions, which can shield bacteria from disinfectant. This is obviously counterproductive.
