Yes, well water can appear oily due to the presence of iron bacteria. These bacteria thrive in water containing iron and other minerals, creating a slimy substance that can leave an oily sheen on the water surface. The oily film may break up into pieces when stirred, indicating iron bacteria as the culprit.
Other potential causes for oily well water include:
- Hydrogen sulfide: This gas can also create an oily film on the water surface, but it does not break up when stirred.
- Incrustation from mineral deposits: These deposits can also cause an oily appearance in well water.
While the oily appearance may be aesthetically unappealing, iron bacteria are generally not harmful to human health. However, they can cause problems like staining, odor, and reduced water flow.
To address oily well water, you may need to treat the water with a water softener or iron filter. If the problem persists, it's best to consult with a qualified water professional.
