Why Does My Well Water Smell or Stain?
A rotten-egg smell is usually sulfur (hydrogen sulfide) or sulfur bacteria; rusty or orange staining is iron, and black specks or staining are manganese — all common in Willamette Valley well water. Most are water-quality issues fixed with the right treatment. If the smell is only in your hot water, it usually points to the water heater, not the well.

What's Usually Causing It — Ranked Most to Least Common
- 01
Iron — rusty / orange staining
Very common locally. Stains fixtures, tubs, and laundry; gives water a metallic taste.
- 02
Sulfur / hydrogen sulfide
The rotten-egg smell. Sometimes seasonal as groundwater chemistry shifts.
- 03
Manganese
Black staining or specks, often paired with iron. Same family of fix.
- 04
Sulfur or iron bacteria
Living biofilm in the well or plumbing — slimy buildup, intermittent smells.
- 05
Water-heater anode reaction
Smell ONLY in the hot side usually means the water heater, not your well.
Safe Checks You Can Do Yourself
Check whether it's all taps or hot-only (hot-only usually means the water heater, which we can confirm). Note the color: orange = iron, black = manganese. This isn't something to just live with — and clear-looking water isn't proof it's clean: arsenic and nitrate, both documented in Willamette Valley groundwater, are odorless and tasteless. We start with a water test (free for well owners), then match treatment — iron filter, softener, UV, or a combined system — to what the test actually shows.
Anything beyond surface checks — pressure switch, 220V wiring, pulling a pump — is our job. Well systems carry high pressure and dangerous voltage; leave them to a licensed pro.
Cost Context — National Ranges
Depends entirely on what the test finds. A single-issue filter (iron or sulfur) is modest. A whole-home multi-stage system with UV is more. We test first, then quote firm — no guessing.
