🤔 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.

🧠 Common causes of Black Sediment in Water

Black sediments in the well water - Causes & Treatment Guide

To remove all the 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 the water. If you have a 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 can easily manifest themselves in water, just like the rust in your water which is bad for health. 

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 black sand or silt in water for proper treatment. For that, you must have knowledge about the types of sediments in the water.

However, it is often asked what are these black specks in the 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.

🧾 Things to follow to remove sediments from black well water

Eliminating Black Sediments from Water

Mostly, the world is facing several problems because of the presence of black stuff in private water as well as municipal water.

As we know, our health mainly depends on the quality of water, thereby, water can improve or damage health according to its quality. That’s why an efficient water system is a need for every person.

Here, some essential steps are written below that you must follow to remove black specks from water:

  • In case you have black sediments in the water, water testing is needed to test the water quality problems. First of all, it is essential to know whether these are sand particles or manganese minerals.
  • Secondly, if you know the type of black silt in well water, you need to install a water filtration system at your home to filter them and avoid the unpleasant odor and bad taste of water. Check this guide to learn how to install whole-house filters.
  • Thirdly, it is necessary to change the corroded pipes of the plumbing fixtures of your home. As many impurities and black specks are caused by bad water pipes, changing them is very beneficial.
  • In addition, moving the location of the pump reduces the number of black specks in your well water. Thereby, a well-placed water pump works wonders and improves the quality of the water.
  • Sometimes an old collapsed well or a faulty filter system results in muddy water that needs to be well repaired to fix the issues.

🤕 What are the effects of Black Silt on your Health?

First of all, you need to know that sand and manganese in your water can badly affect the functioning of the nervous system and might result in many diseases like Parkinson’s and many more.

In addition, children and teenagers absorb these sediments quickly as compared to adults. In this sense, these black particles majorly affect the learning ability of infants.

Moreover, sediments that have disease-causing microorganisms such as viruses will have a negative effect on your physical and mental health. Therefore, if you feel the blackish color of the water, you must test your water as soon as possible.

💭 How to get rid of black sediments in well water?

The black sediments in well water are triggered by many things. However, the primary source of these particles in water is the gravel parts of the well or many home water filter systems. Thereby, when the tap water is grilled, it is mainly linked with iron to act as the screen.

Particularly, the outdated screen allows the sediments to grow in the water and increases iron and manganese. This also shows that your water pump is placed in the wrong place.

✅ Solution – Step-by-Step Approach for Sediment Removal

  • First of all, changing the place of the water pump will surely improve the quality of water which will help eliminate sediments.
  • Secondly, the solution is to lift the pump higher away from the floor of the well. For this, you must drill the well correctly and use the latest screen in the water purification system.
  • Thirdly, install an updated screen on the top of the pump, eliminating all the unwanted sediments from the water before it reaches the tap.
  • Another way to avoid these sediments quickly is to place a sand separator between the pump and the pressure tank on the ground. Thereby, this little gadget spins the water and sets all the black specks at the bottom of the water tank.
  • You can use chlorine or other oxidizing agents to remove the black specks in your water. Moreover, iron filters are also great to protect your well water column if the issue is caused by iron oxide in it.
  • Also, you can install the best sediment filter at the point of entry to remove these black sediments in your water and stains.
  • If old rubber hoses or water pipes are the reason for black particles in your water, replace the hoses and the pipes to fix the issue permanently.
