Well water treatment in Canada: iron, sulphur and UV
Private wells need more than a pitcher filter. How iron filters, sulphur treatment and UV disinfection fit together after a proper water test.
Start with a lab test
Test for bacteria (total coliforms and E. coli), nitrates, hardness, iron, manganese, sulphur, pH and TDS. Add arsenic, uranium or PFAS where local geology or industry suggests risk.
Iron and sulphur
Oxidizing filters, aeration and specialized media handle staining and rotten-egg odour. Softeners alone rarely solve heavy iron.
UV disinfection
Ultraviolet systems kill bacteria and viruses when the water is already clear enough for UV to work. Sediment and iron pretreatment is often required first.
A typical well train
Sediment → iron/sulphur → softener → carbon → UV → optional kitchen RO.
