Iron and manganese removal

Eagle Point's Agate Desert and Western Cascades volcanic-bedrock wells fit Oregon Health Authority's "reducing groundwater" pattern exactly: iron, manganese, and hydrogen sulfide co-occur, often producing black iron-sulfide deposits at fixtures (Oregon OHA — Iron and Manganese in Groundwater).

The right treatment depends on form, concentration, and pH. For dissolved iron under 3 mg/L without manganese, an air-injection oxidation tank with manganese-coated media handles it. For manganese, or for iron above 3 mg/L, manganese greensand or Katalox Light with potassium permanganate regeneration is the standard media. Never run iron-bearing water through a plain softener — fouls the resin fast.

Jacksonville's foothill and Applegate-area private wells fit the regional "reducing groundwater" pattern: iron and manganese co-occur with hydrogen sulfide and produce black iron-sulfide staining (Oregon OHA).

Iron above 0.3 mg/L fouls standard softener resin; specialty pretreatment is required before any salt-based softener is sized. For most Jacksonville-area wells with measurable iron, manganese greensand or Katalox Light is the right primary filter.

White City wells in the Agate Desert volcanic aquifer share the regional iron, manganese, and H2S co-occurrence pattern documented by Oregon Health Authority (Oregon OHA — Iron and Manganese in Groundwater).

For White City wells, iron and manganese testing should run alongside the area's larger industrial-VOC concern — a single comprehensive well panel is more efficient than separate visits. Treatment design depends on whether iron, manganese, and H2S are present together, plus the specific pH and alkalinity numbers.

Shady Cove's private-well universe sits in Western Cascades volcanic geology with classic reducing-aquifer chemistry — iron, manganese, and hydrogen sulfide co-occurring at variable concentrations (Oregon OHA — Iron and Manganese in Groundwater).

Treatment design is well-by-well. For low-to-moderate iron (under 3 mg/L) without manganese, air-injection oxidation handles it. For higher iron or any measurable manganese, the standard answer is manganese greensand or Katalox Light with appropriate regeneration — paired with a sediment pre-filter and, where indicated, an H2S oxidation step.

Gold Hill area wells in gold-belt and surrounding alluvial geology commonly carry iron and manganese alongside the documented arsenic risk. Oregon Health Authority documents the regional reducing-aquifer pattern (Oregon OHA).

Treatment is sized to the specific iron, manganese, pH, and alkalinity numbers — with a backwashing media filter (manganese greensand or Katalox Light) as the typical primary stage. Pretreatment iron filters are non-optional before any softener install.

Klamath Falls city water generally runs low iron and manganese — but private wells in the basin, especially deeper geothermally influenced wells, can carry both. The Conger, Debbie, Fremont, Hilyard, and Wocus city wellfields all report measurable manganese in the 2024 CCR (Klamath Falls 2024 CCR).

For private wells with iron, manganese, or H2S, the standard treatment is a manganese greensand or Katalox Light filter sized to peak flow, with an oxidation pretreatment step where indicated.
