The Most Common Well Water Problems in Central Indiana

1. Iron (Orange or Rust Stains)
Iron leaves reddish-orange stains on sinks, tubs, toilets, and laundry. It often appears in wells in Madison, Delaware, and Henry counties.
Cause: Naturally occurring iron in groundwater or oxidized iron once it reaches air.

2. Sulfur (Rotten Egg Smell)
The rotten egg odor usually means hydrogen sulfide gas or sulfur-producing bacteria.
Common in deeper wells in Hamilton and Tipton counties.

3. Hard Water (Calcium & Magnesium)
Nearly every county in Central Indiana has hard water.
Signs: Scale buildup on fixtures, cloudy spots on dishes, shorter appliance lifespan.

4. Sediment or Sand
Cloudy or gritty water may indicate:

• A dropping water table
• A failing screen
• Aquifer disturbance after storms
• Pump set too low

5. Low pH (Corrosive Water)
More common in rural areas, causing pipe corrosion and metallic tastes.

Why Water Quality Varies From One Home to Another
Even homes in the same area can have completely different water chemistry. That’s because:

• Aquifers vary across short distances
• Soil layers differ dramatically
• Wells draw from different depths
• Seasonal rainfall impacts water chemistry
• Older wells may have deteriorated screens or fittings

Central Indiana groundwater isn’t uniform — and that’s exactly why diagnosis matters.

How to Diagnose the Issue
A licensed professional will use a combination of:

• On-site water sampling
• Flow and pressure testing
• Aquifer depth evaluation
• Drop pipe inspection
• Pump performance analysis
• Water chemistry testing (iron, sulfur, hardness, pH, bacteria)

Treatment Options Based on the Problem:
Iron

• Iron filters
• Sediment filtration
• Oxidation systems
• Chlorination (for bacteria-based iron problems)

Sulfur

• Shock chlorination
• Iron Filters
• Aeration systems
• Activated carbon filtration
• Hydrogen peroxide systems

Hard Water

• Water softeners
• Scale reduction systems

Sediment

• Sediment filters
• Screen rehabilitation
• Pump repositioning

Final Thoughts
Water quality issues are common — but fixable. Proper diagnosis is the key to finding the right solution, and the proper diagnosis starts with hiring an experienced, licensed professional.
