Lower, soluble iron concentrations, without the presence of bacteria, can be treated with filters or with phosphate additives placed in the well's pressure tank. Zeolite softening agents will remove iron as well, although this can cause the iron to crystallize and accumulate in pipes. Serious iron problems can be treated with the installation of a manganese green-sand filter, which can remove both soluble and insoluble iron, although the filter must be cleaned and recharged periodically to remain effective. A bleach treatment will kill iron bacteria and can be used in conjunction with other treatments.
