Signs to look for
Orange or brown staining often points to iron. Black staining can indicate manganese. A rotten-egg smell usually means hydrogen sulfide gas.
Common treatment approaches
Oxidation filters (air injection, chlorine, or hydrogen peroxide) convert dissolved iron and sulfur into particles that a filter bed can capture. The right approach depends on concentration, pH, and whether iron bacteria are present.
When to call a professional
High concentrations, iron bacteria, or a combination of problems may need a professionally designed system. Ask installers for written specs and warranty terms.
