The Borehole water brown stains.

What cause the Borehole water brown stains?

It is iron and manganese that comes in contact with oxygen and then the water turn brown.
The first that people would inform you is that it is the Iron in the borehole water.
Sometimes they will include the word iron or Manganese.
That is a fact and everyone agrees.

My borehole water turning brown after initial white.

That is because the water receive oxygen and the iron or manganese start to oxidize.
The iron and manganese is dissolved and once oxygen reach a certain level it starts to oxidize.

Brown stains from water.

Some time ago a client contacts me and complained that the stuff that’s been washed have brown stains on. She presents me with the latest water analysis of the borehole water.
The Iron reading was 1.4 and the manganese was 1.2.
You would say that it could not be the iron or manganese in the water.
That was my response as well.
While looking to the report I asked the woman if the water is been stored in to water tanks.
Her reply was that they have three ten thousand litres JOJO tanks where the water is been stored.
Plenty of Oxygen and a very small amount of Iron and Manganese in a container for a few days is all that is needed to have a big brown stain problem.

How to treat the cause of brown stains in water.

You need a proper iron and manganese treatment system.
Please don't run to the nearest person that claim that they treat water.
Treatment of iron and manganese is complicated.
There is some things that must be taken in consideration.
Things like the ph, iron and manganese level can show low but you must know the correct level for it.
The SANS standard is for human consumption and not for normal use.
The level for normal use is lower than the SANS standard.
Stay away from the Big Blue Systems, they don't work.

A cause of the Borehole water brown stains.

This is when the water have this brown stuff in.
If the water lay on the grass you will notice a brown mass between the grass.
They are wrong! Yes!
That is not the real cause of the brown stains.
The real cause of the brown stains caused by borehole water is the result of bacteria in the water.
The Bacteria is called “Gallionella ferruginea”.
These bacteria thrive on the Iron and Manganese is the water.
When you see a high iron or manganese reading you see brown.
