What is the Manganese in Water?

Manganese in Water

If you have a private well system installed, then the quality of water becomes poor from time to time as per the usage. Mainly, this happens because iron or manganese began to grow in water.

Manganese is a heavy mineral found in rocks and soils, and even in groundwater. In case it is present in large amounts in the water, the water from the well or spring loses its pure texture and gives it a very dusty and brownish color over time.

Such contaminated water is also bad for health. You can remove manganese from water as well as hard water by using a good-quality water softener or a home water filter.

Why Is My Well Water Black: Common Causes of Sediment in Water

Black sediments in the well water - Causes & Treatment Guide

To remove all the black sediments from water, it is important to know the causes of these particles first.

Almost every well water may have a small number of sediments in it, but when they increase with time, they can become harmful to your health.

The common causes of these sediments are explained below:

Low Water Table

If the well has a low water table then the black specks increase quickly. The lower water levels cause many sediments like iron, clay, and black sand in the bottom of your well water.

Well having Low Water Table

Furthermore, these sediments also increase when the walls of the aquifer are damaged causing black water in the water wells.

Wrongly placed Well pump

A wrongly placed well pump is also one of the major reasons for the black particles in well water.

If you have a new pump that is too deep or not placed correctly, then indeed, the growth of these sediments increases in the water which can also damage your well pump.

Do note that the black specks and bits can easily manifest themselves in water, just like the rust in your water which is bad for your health. This can be the major reason why is black water coming from the well.

Faulty Filters

Primarily, the purification of water depends mostly on the water filtration system nowadays. Many people have installed filter systems in their houses to get 100% soft and pure water in their fixtures.

But if anyone has installed a poor-quality water treatment system, then surely, it will not perform well, and won’t be able to eliminate black sediments in your well water.

On the other side, an efficient whole-house water filter removes all the black specks and impurities from the water which improves the water quality. You will get safe, healthy, and clean water for drinking from your faucets.

So, you should consider replacing the filter with an effective one that can remove the pieces of sand or silt from the water as soon as possible.

Faulty Water Heater or Pipes

If you find black water only when you turn on the water heater, you should check your water heater and hot water pipes for corrosion.

You can get help from the plumber to check the health and condition of the water heater and the pipes.

If the water pipes are corroded and rusty, the water shows up red, brownish orange, or even black color, you need to get the plumbing system repaired.

Types of Black Specks in Water – What are these?

Types of Black Specks in Water - Black Sediment in Well Water

It is essential to learn more about silt or black sand in well water for proper treatment. For that, you must have knowledge about the different types of sediments in the water.

It is often asked what are these black specks and how to get the sediment out of well water. For this, detailed research is explained below:

Silt or Sand

If the water pump is placed in the wrong place, then sediments will surely grow in the water.

Many people observe tiny sediment growth in the well water, primarily brown or black due to this wrong placement issue. Mainly, these are the particles of sand, silt, or black debris in your water system.

In addition, these sandy sediments are caused due to the presence of screens in well water. In this case, installing a new and superior quality screen will help improve the quality of water.

Unwanted Minerals

According to research, black sediments in water are also unwanted minerals. When mineral deposits are in a water source, they change the texture and taste of the water. Moreover, they also contribute to the development of black-tinged water.

The most common minerals present in water are manganese and iron which make your water taste or smell like metal. You can easily filter them using whole-house iron water filters.

Sometimes, the presence of these two minerals in excess makes the water hard. In addition, they are black and give a rusty color to the well water.

As these minerals are very harmful, they also stain your clothes. In addition, the water pipes of the house will surely be affected by these minerals and become dirty.

Rust Particles

The particles of rust are mostly brown or orange but seem black sometimes in the water. These particles will damage not only the quality of water but also your health.

However, rust particles in water are not always a severe issue because they are effortless to eliminate. For elimination, you just run the water in your faucets for a few minutes.

Run water faucets for a few minutes

Most probably, with a continuous flow of water running out of the tap, these particles will get eliminated from the water.

Granulated Activated Carbon particles

In some cases, GAC is also found in water which is black. Granular Activated Carbon is mainly a substance that is used in small projects of filtration.

However, these GAC substances can be dangerous sometimes if they are in larger quantities in water.

Key Point: Do you know that for eliminating these substances from water, you don’t need to call for a professional plumber?

The reason is that anybody can remove these particles at home easily.

For this, you must check the manual of the system and replace the filtration cartridge. By replacing the cartridge of the filter, these GAC particles escape from the water.
