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 between the age of 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 resulting in a disease that resembles Parkinson.

So it’s very important for children and pregnant women to have clean drinking water free from manganese and other contaminants.

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; check if you can see black/brown fragments from the water.

The GAC particles are tough, irregularly arranged and shaped like coffee beans.Sediments in Water From Well

What to do if your well water has black sediment

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 departments website for a 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 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 for 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.)

Overtime, 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.
