Well Water Quality in Ada County
Ada County well water varies dramatically by location and depth. Common issues include elevated hardness (8-20 GPG), iron (causing orange staining), manganese (causing black staining), and in some areas elevated arsenic or nitrates. Annual testing through the Idaho Department of Environmental Quality is strongly recommended.
Essential Well Water Treatment
Most Ada County wells benefit from: a water softener for hardness, a sediment filter for particulates, and potentially an iron filter if iron exceeds 0.3 mg/L. UV disinfection provides protection against bacteria without chemicals. A reverse osmosis system at the kitchen sink provides premium drinking water.
- ✓ Water softener: Essential for most Ada County wells
- ✓ Sediment filter: Catches particulates before they enter plumbing
- ✓ Iron filter: Needed if iron exceeds 0.3 mg/L
- ✓ UV disinfection: Chemical-free bacterial protection
- ✓ Reverse osmosis: Premium drinking water at point of use
Pressure Tank and Pump Maintenance
Your well pump and pressure tank are the heart of your water system. Pressure tanks should maintain 40-60 PSI. Signs of failure include: pump cycling on and off rapidly (waterlogged tank), low pressure, and no water at all. Pumps typically last 10-15 years, pressure tanks 10-20 years. Annual inspection prevents unexpected failures.

Idaho requires well permits for new wells and well abandonment permits for decommissioning. If you're connecting to municipal water, your old well must be properly sealed to prevent contamination of the aquifer. We coordinate with licensed well drillers when needed.
Frequently Asked Questions
How often should I test my well water?
Test annually for bacteria (coliform), nitrates, and pH. Test every 3-5 years for a full mineral panel. Test immediately if you notice changes in taste, odor, or color.
My well water smells like rotten eggs — is it safe?
The smell is hydrogen sulfide gas, common in some Ada County wells. It's not harmful at typical levels but is unpleasant. An oxidizing filter or aeration system removes the odor.
How much does a well water treatment system cost?
Basic softener + sediment filter: $1,500-$3,000. Complete system (softener + iron filter + UV + RO): $4,000-$8,000. Cost depends on your specific water chemistry and flow requirements.
