Iron-related bacteria (IRB) in a groundwater well

IRB can be identified through several signs, including visual clues, odours, and laboratory testing. Here’s how you can tell if your well is affected:

Signs of Iron Bacteria in a Well

1. Slimy Deposits

   - A reddish, brown, orange, or yellow slime in your toilet tank, plumbing fixtures, or well components.

   - A greasy or jelly-like biofilm forming on pipes or well casings.

2. Discoloured Water 

   - Water may appear rusty, reddish, brown, or have an oily sheen on the surface.

3. Unpleasant Odors 

   - A swampy, musty, or sewage-like smell (sometimes resembling rotten eggs) due to bacterial activity.

4. Clogging Issues 

   - Reduced water flow due to buildup in pipes, pumps, or filters.

   - Increased maintenance needed for well screens and plumbing.

5. Floating Particles 

   - Rust-coloured clumps or stringy material in standing water (e.g., in a bucket or toilet bowl).

Testing for Iron Bacteria

- DIY Testing: Fill a clear glass container with water and let it sit. If reddish-brown or slimy particles settle at the bottom, it may indicate iron bacteria.

- DIY Observation: Open a pipe and look to see if it is clogged with mushy brown iron oxide.

- Laboratory Testing: A professional water test for iron bacteria can confirm their presence. Contact a local water testing service or health department for guidance.

Treatment Options

If iron bacteria are found, treatment options include: 

- Chemical Treatment: Using special biocides or acid treatments such as BoreSaver Ultra C and BoreSaver Multikleen (often performed by professionals). 

Shock Chlorination: Adding a high dose of chlorine to disinfect the well. 

- Regular Well Cleaning: Flushing and scrubbing well components. 

- Filtration Systems: Installing filters or water treatment systems to reduce iron buildup.
