How To Fix Acidic Well Water?

To fix acidic well water, use a whole-home acid neutralizer with Calcite if your water's pH is above 6.0, and a Calcite-Corosex blend if your water's pH is below 6.0. Here's a comprehensive guide to fix acidic well water:


Step-by-Step Process to Fix Acidic Well Water


1. Test Your Water

  • pH Testing: Acidic water typically has a pH of less than 7. Use a home testing kit or send a sample to a certified laboratory for precise results.

  • Additional Tests: Check for other contaminants such as heavy metals (lead, copper, iron), which can be leached from pipes by acidic water​.


2. Identify the pH Level

  • Mildly Acidic (pH 6.0 - 6.5): Slightly acidic water can cause minor corrosion and taste issues.

  • Moderately Acidic (pH 5.5 - 6.0): More significant corrosion and potential health risks from metal leaching.

  • Highly Acidic (pH below 5.5): Severe corrosion, strong metallic taste, and higher health risks​.


3. Choose a Treatment Method

  • Neutralizing Filters (our preferred method):

    • Calcite Filters: Use filters containing Calcite (calcium carbonate) to raise the pH. Suitable for mildly acidic water.
    • Calcite-Corosex Filters: For more effective treatment, combine calcite with Corosex (magnesium oxide). This is useful for water with a lower pH as it neutralizes more effectively​.


  • Soda Ash Injection Systems:

    • Soda Ash (Sodium Carbonate): Injecting a soda ash solution into the water can neutralize the acidity. This method is suitable for highly acidic water and provides precise control over pH levels.

    • Installation and Maintenance: These systems require a metering pump and regular monitoring to maintain the correct pH balance​.


  • Chemical Feed Pumps:

    • Sodium Hydroxide: Another option is to use a chemical feed pump to inject sodium hydroxide (caustic soda) into the water. This method can handle extremely low pH levels but requires careful handling and monitoring​.


4. Install the Chosen System

  • Professional Installation: While some homeowners may install simpler systems themselves, hiring a professional ensures proper setup and optimal performance.

  • Location: Place the system where water enters your home to ensure all water is treated​.


5. Regular Maintenance and Monitoring

  • Replenish Media: For neutralizing filters, periodically replenish the Calcite or Corosex media to maintain effectiveness.

  • Monitor pH Levels: Regularly test the water’s pH to ensure the system is working correctly and adjust settings as needed.

  • System Checks: Regularly inspect and maintain the injection system or chemical feed pump to prevent malfunctions​.


6. Additional Considerations

  • Add A Sediment Filter: Install a sediment filter to prevent clogging of neutralizing systems if your water contains other particulates.

  • Add An Iron Filter: Iron filters are effective at remof your water has have iron iron, manganese, hydrogen sulfide, arsenic, zinc, copper, lead, radium, and other heavy metals.

  • Professional Help: Engage a certified water treatment specialist for regular maintenance and to address any issues promptly​.


By testing your water, selecting the appropriate treatment system, and maintaining it regularly, you can effectively neutralize acidic well water, protect your plumbing, and ensure safe, pleasant-tasting water for your household.
