So, let’s get started!

Main Causes of black particles in well water

1. Mineral Traces

If your well water is black, this can be caused by iron and manganese in the water. A high level of manganese usually appears as black/dark blue sediments in the water.

Health effects of manganese in drinking water

Manganese is mainly consumed from drinking tap water. Showering or bathing in manganese contaminated water doesn’t increase your exposure because chances of skin penetration are very low.

Children aged 15 years and below are prone to absorb more manganese. High concentrations of manganese tend to affect the learning ability of a child and nervous system breakdown. This may ultimately result in a disease that resembles Parkinson’s.
So it’s very important for children and pregnant women to have clean drinking water free from manganese and other contaminants.

2. Water Pipe Corrosion

Rust particles chippings from an old, brown or black plumbing pipe system usually break off from the inner parts of the pipes and wind up in your glass of water.

You can do a D-I-Y inspection to check if your house or city pipes system leading to the house is corroded, by running cold water for a minute or two. You can then check for the presence of black/brown fragments from the water.

Call a plumber or local water authority to check if the steel pipes within your house plumbing system are probably rusty before they can spring a leak.

3. Disintegrating Rubber in Well Water

Experiencing oily, smudgy junks in your tap water? Generally, this should be a rubber hose pipe leading to your water heater that is disintegrating due to the effect of chloramine or chlorine.

Fortunately, the new version of rubber hose pipes is made from water disinfection-resistant lining that protects them from the negative effect of chlorine or chloramine; if your flex hose connection is from the old version, you need to call a plumbing professional to inspect and even replace the hose.

4. Black Sand in Well Water

If you are using a private well as your primary source of water, and notice that the water draw contains small brownish or blackish pieces of silt or sand.

These particles are likely to damage your washing machine, dishwasher and as well, ware out the well pump.

Possible remedies include: for a new well, you may let water run for two to four hours non-stop; this should be for a new well. For an older well, there may be a need for a screen replacement or installation.

5. Granular Activated Carbon

Granular Activated Carbon is currently very popular, and the majority of water filter companies use them as a filtration agent in their cartridges.

The GAC particles are tough, irregularly arranged and shaped like coffee beans.Sediments in Water From Well
These GAC particles have a very short service life, and when they get filled or chocked with contaminants over a while, they loosen from the cartridge and end up on your water glass.

It is thus advisable to check the water filtration system manufacturer instructions for guided steps to take in solving the problem.

From our point of view, you need to test the well water for iron, silica, bacteria, hardness, and manganese.

You can visit your local health or state department’s website for certified laboratory inspection.

2. In a case where you find dark brownish rocks or sand particles when you draw water from your faucet.

It might be that your well pump that is way down below the set standard or a minimum of fifteen to twenty feet high from the bottom of the well. You can resolve this problem by raising the pump shaft thus increasing the distance between the pump shaft and the base of the well.

3. Another source of black sediments in well water might be worn out wall casing. (Casing is a lined PVC plastic placed inside the well wall that allows water to penetrate through and at the same time keep out silt and sand out.)

Over time, the casing screen gadgets; then allowing silt sediment, and sand to get into the well. It is advisable to contact your well driller for further confirmation.
