10 Signs of Contamination in Well Water

January 3, 2025

Your well is a vital source of clean and safe water for your household, but contamination can compromise its quality and pose health risks. Identifying the signs of contamination early is essential to maintaining your well water’s safety. Here are 10 common signs that may indicate your well water is contaminated.

1. Unusual Taste or Odor

A metallic, salty, or sulfur-like taste or odor can signal contaminants like iron, manganese, or hydrogen sulfide gas in your water.

2. Discolored Water

Cloudy, brown, or reddish water often indicates the presence of sediment, rust, or organic matter, which may point to surface contamination or aging pipes.

3. Slimy or Stained Fixtures

A slimy residue or stains on sinks, toilets, and tubs could indicate excessive bacteria, algae, or mineral buildup.

4. Unexplained Illnesses

Recurring gastrointestinal issues in your household might be linked to bacteria, viruses, or parasites in your water.

5. Presence of Sediment

Visible sediment or particles in your water could stem from disturbed well sediment, damaged equipment, or runoff contamination.

6. Changes in Water Pressure

Fluctuating water pressure may signal a clog or damage caused by debris or contamination within your system.

7. Recent Nearby Construction or Flooding

If heavy construction or flooding has occurred near your property, it may have introduced contaminants into your well.

8. Positive Water Test Results

Routine water testing revealing high levels of nitrates, bacteria, or other harmful substances is a definitive sign of contamination.

9. Algae Growth in the Well Area

Algae growth near your well cap or in the surrounding soil can indicate nutrient-rich runoff has infiltrated your water source.

10. Unusual Corrosion in Plumbing

Rapid corrosion in pipes and fixtures may result from high acidity or chemical contamination in the water.
