- Rotten-egg smell is usually hydrogen sulfide — treatable, not dangerous, and very common in these aquifers.
- Orange/brown stains point to iron; white scale to hardness. Both are treatment questions, not drilling questions.
- Test, then treat. Any treatment worth buying starts with a water test — nitrates and bacteria matter on farms and older wells in particular.
