Causes of Brown Well Water

Iron and Manganese

One of the primary reasons for brown well water is the presence of iron and manganese. These minerals can be found in groundwater and can cause discoloration when present in high concentrations. Ferrous iron is soluble and can turn into ferric iron, which is visible as rust particles. Additionally, manganese can cause a brownish-black coloration in your water. To mitigate this issue, you can use iron and manganese filters or oxidation-based water treatments.


Tannins in well water are another common cause of brown water. These natural organic materials come from peaty soil and decaying vegetation. High levels of tannins in your well water can give it a tea-like color and sometimes a bitter taste. While tannins are not usually considered harmful, they can cause aesthetic problems. Consider using carbon filters or anion exchange treatment systems to reduce tannin levels in your well water.

Sediment and Silt

The presence of sediment and silt in your well water can also contribute to brown water. Excessive sand, sediment, or fine particles can cause water to appear murky or muddy. To resolve this issue, you can install sediment filters or pre-filters in your water treatment system to remove such particles before they reach your taps.

Rusty Pipes

Rusty pipes can be a leading cause of brown well water in your system. Older pipes made of iron or steel can corrode over time and release rust particles into your water. Rust in brown well water can cause an unpleasant taste and can stain your fixtures and appliances. Replacing rusted water pipes or adding a filter that captures rust particles before they reach your taps can help alleviate this problem.


Iron bacteria can also contribute to brown well water. These bacteria usually thrive in water containing high concentrations of iron, forming slime and rust deposits. This can cause foul taste, odors, and discoloration. You can eliminate iron bacteria by disinfecting your well using chlorination or adding a continuous chlorination device.

Organic Material

Organic material such as leaves, twigs, and plant debris can enter your well and cause brown well water. When these materials decompose, they might release tannins and other substances that discolor the water. Proper well maintenance, including sealing access points and ensuring proper drainage, can help prevent organic material from entering your well.

By testing your well water for iron, manganese, tannins, and bacteria, you can identify the cause of brown well water and take appropriate action to address the issue.

Solutions for Brown Well Water

Sediment Filtration

One method to tackle brown well water is by using sediment filters. These filters help remove sediment buildup, dirt, and sand from your water. You can install a whole-house sediment filter at the main water supply to ensure clean water throughout your home. Some popular sediment filtration options include:

  • Cartridge filters: Replaceable filters that trap sediment.
  • Spin-down filters: A reusable filter that you can clean when it becomes full of sediment.

Iron and Manganese Removal

If your well water contains a high amount of iron and manganese, using an iron filter or a water softener with iron removal capabilities will be beneficial. Greensand filters are an excellent option – they use potassium permanganate to remove iron and manganese from raw water. In some cases, a combination of chlorine and potassium permanganate (in specific filters) may be used for more effective results.

Tannin Removal

Tannins can cause brown water and lead to a variety of taste and odor issues. Reverse osmosis (RO) systems can effectively remove tannins from your well water. The RO system passes your water through a membrane, which filters out contaminants, including tannins. You may need to combine this with a pre-filter (such as a sediment filter) for optimal performance.

Bacterial Removal

To prevent bacterial contamination in your well water, chlorination is a widely used and persistent disinfecting method. By introducing chlorine into your water, you effectively eliminate harmful bacterial colonies. Regularly chlorinating your water, especially after heavy rainfall, can help guard against microbial and bacterial contamination.
