Abstract: A method and apparatus for cleaning a well wherein chemicals are applied to the well screen with steam. The well screen may be first washed with a sterilizing agent, and subsequently a chemical mix is added to the steam. The chemical mix includes a sterilizing agent, an acid, and perhaps a surfactant. The well is capped during treatment so the well becomes pressurized; and, the chemical mix is forced out beyond the well screen. The surfactant aids in penetrating the clog, while the sterilizing agent kills any plant or animal life that is causing or contributing to the clog. Some sterilizing agent may remain to prevent regrowth of life forms that may feed on other chemical components. The well may be surged to assist further in breaking up the mass clogging the well.
