Ion exchange is the primary household technology for measured hardness. Read the hard-water guide.
Oxidation, specialty media and filtration depend on form and chemistry. A softener has a limited role in some cases. Iron guide.
Dark deposits may respond to oxidation-filtration when pH and chemistry allow. Manganese guide.
Find the source first — well, heater or plumbing — then aeration, oxidation or rated carbon as the chemistry allows. Hydrogen-sulfide guide.
Neutralizing media or a controlled feed raises low pH before it reaches copper plumbing. Acidic-water guide.
Sediment filtration protects downstream stages; it does not remove dissolved constituents. Compare filtration equipment.
Nitrate, arsenic and bacteria require conservative, result-specific and equipment-specific planning — only devices rated for the constituent and its form. Nitrates · Arsenic.
Correct the source, apply appropriately designed disinfection and confirm with retesting. Ordinary RO is not a bacteriological safety solution. Bacteria guide.
| Category | Typically targets | Does not address | Usual placement | More |
|---|---|---|---|---|
| Softening (ion exchange) | Measured hardness; limited role for low dissolved iron | Bacteria, nitrate, arsenic, odor, sediment | Point of entry | Equipment |
| Oxidation / filtration media | Iron, manganese, hydrogen sulfide when chemistry allows | Hardness, dissolved contaminants it is not rated for | Point of entry | Equipment |
| Neutralization | Low pH before copper plumbing | Staining already caused; other constituents | Point of entry | Equipment |
| Sediment filtration | Selected particles; protects downstream stages | Dissolved hardness, nitrate, arsenic, bacteria | Point of entry | Equipment |
| Carbon | Rated taste, odor and disinfectant goals | Dissolved metals, nitrate, arsenic, bacteria | Either | Equipment |
| Point-of-use reverse osmosis | Selected dissolved constituents only when the exact device is rated | Whole-house objectives; bacteriological safety | Point of use | Equipment |
| UV / disinfection | Microbiological safety after source correction, with proper dose and pretreatment | Chemicals, metals, hardness | Point of entry | Equipment |
Use this guide for private-well testing frequency, certified laboratories and symptom-based testing questions.
Review California guidance for testing a domestic well and interpreting laboratory results.

No. The objective determines point-of-entry versus point-of-use treatment.
Use appropriate post-treatment testing and ongoing service based on the identified issue.
Rarely. Each category addresses specific constituents; more than one measured condition usually means more than one stage, ordered so each protects the next.
A softener may have a limited role with low levels of dissolved iron when chemistry allows, but oxidation-filtration is the usual approach. The form and concentration in your result decide.
No. Ordinary RO is not a bacteriological safety solution. Correct the source, use appropriately designed disinfection and confirm with retesting.
It depends on the water and the stage. Sediment loads, hardness, iron and use all change intervals, so service follows monitoring rather than a fixed number.
Begin on the well-water services page: confirm the source, document the concern and test before choosing equipment.
Tell Water Fixers about the well, the symptoms and any test results. We can plan the right treatment.
