If you've noticed that your well water has taken on a yellow hue, you may be wondering what's causing the discoloration. Identifying the source of the problem is crucial to finding the right solution and ensuring the water is safe to use. Cause #1 - Iron Ferric iron is a type of dissolved iron that has been oxidized and turned into a solid. When water containing ferric iron is exposed to oxygen, it will turn yellow or brown. If you notice that your well water is yellow and has a metallic taste, ferric iron might be the culprit. While it doesn’t pose an imminent health risk, it is unpleasant and causes stains and clogs appliances. The best way to remove ferric iron from well water is to use a water filter that is specifically designed to remove iron, such as the Springwell Whole House Iron Filter. Cause #2 - Tannins Tannins are natural byproducts of decaying vegetation and can be picked up by water as it seeps through swampy or peaty soils on the way to your well's aquifer. They can give water an unpleasant taste, smell, and color. Tannin filters are the most common way to remove tannins from well water. These filters work by absorbing tannins into a filter media, which can then be flushed out of the system. A good example is the Springwell Tannins System which not only removes organic material causing yellow water but also softens the water as well. Cause #3 - Rusty and corroded pipes The pipes of old wells are mostly made of iron, which tends to rust without proper maintenance. As water flows through these pipes, it picks up small particles of iron and rust which turns the water yellow. The best way to fix rusty pipes is to replace them with new pipes. Although it can be costly, it’s the ideal solution. Getting a qualified professional to do the job is essential to ensure that it’s done correctly. Cause #4 – Sediment and particles Sediment in your well water can also cause it to appear yellow. This can be due to the presence of organic material, minerals, or other particles that have settled at the bottom of the well. A sediment filter is an effective solution for removing sediment from your well water. The Springwell Tannins System, mentioned earlier, is also effective at removing sediment along with tannins. Cause #5 - Iron bacteria Iron bacteria are microscopic organisms that live in water and soil. They get their energy by oxidizing iron, manganese, and other metals, which can cause staining, clogging, and discoloration of water. Yellow well water isn’t the only sign of iron bacteria contamination; they also turn water orange, red, and even brown. You can easily identify their presence in your well by a swampy or oily taste. Iron bacteria are difficult to remove and often require a combination of pasteurization, chlorination, and filtration. Therefore, it’s better to call for professional help.
