Coliform and E.coli Contamination in Your Well Water

How to Deal with Coliform and E.coli Contamination in Your Well Water

Discovering Coliform or E.coli in your well water can be unsettling. These bacteria can indicate the presence of harmful pathogens that pose serious health risks. Here’s a comprehensive guide on identifying symptoms, understanding common causes, and tackling such contamination effectively.

Well Water Testing

Recognizing the Symptoms and Causes

Symptoms of Contamination

Water contaminated with Coliform or E.coli might not always have a noticeable taste, smell, or color change. Therefore, regular testing is crucial. Symptoms of exposure in humans can include nausea, vomiting, fever, abdominal cramps, and diarrhea. If you experience these symptoms and use well water, consider testing your water immediately.


Common Causes

Coliform and E.coli can enter well water through several pathways:


  • Runoff from agricultural areas
  • Faulty septic systems
  • Floodwaters
  • Harmful waste from animal farming

Approaches to Prevention and Maintenance

Regular Testing

Testing your well water at least once a year for Coliform bacteria and E.coli is essential. These tests are often provided by local health departments or can be conducted by certified laboratories.

Well Water Testing

Proper Well Construction and Maintenance

Ensure your well is correctly located, constructed, and maintained. The well should be sealed adequately to prevent surface water from entering. Regular inspections by professionals can identify potential issues before they lead to contamination.


Managing Runoff

Diverting surface water away from your well can prevent contaminants from entering your water supply. Keep the area around your wellhead clear of debris, fertilizers, and pesticides.

Remedying Coliform and E.coli Contamination

Upon detecting Coliform or E.coli, stop using the water for consumption immediately. Use bottled water or boil tap water for at least one minute before drinking, cooking, or washing dishes.


Shock Chlorination

One of the most effective methods to eliminate bacteria from well water is shock chlorination. This process involves adding a strong chlorine solution to your well water and plumbing system. It’s essential to follow specific guidelines for shock chlorination to ensure safety and effectiveness.


Centers for Disease Control and Prevention (CDC) provides a detailed guide on performing shock chlorination.


Water Treatment Systems for Coliform and E.coli in Your Well Water

For long-term solutions, consider installing water treatment systems such as:


  • UV Light Filters
  • Reverse Osmosis Systems
  • Chlorine Injection Systems

These systems can effectively remove or kill bacteria, ensuring your water is safe for consumption. Always choose products certified by the National Sanitation Foundation (NSF) for water safety.


Preventing Future Contaminations

Regular Inspections and Maintenance

Conduct annual well inspections and water quality tests. Ensure the well cap is intact, and there are no cracks in the well casing.


Landscaping and Runoff Management

Proper landscaping around your well can prevent water contamination. Plant grass or other vegetation to absorb excess water and reroute drainage systems away from your well area.
