Hi,
I Live in Aduthurai, near Kumbakonam, Tamil Nadu.
We have dug a 140 feet borewell and tested the water and following are the
results.
Colour - Slightly Yellowish
Odour - Objectionable
Column A Column B Our Borewell reading
======== ======== ==============
Turbidity 1 10 140
Iron as Fe (mg/l) 0.1 1 2.67
Total Dissolved Solids 500 2000 595
pH 7.0to8.5 6.5to9.2 7.1
Alkalinity Total as
CaCO3 200 600 360
Total Hardness as CaCO3 200 600 290
Magnesium as Mg 30 150 36
The Filter report says that
(CPHEEO Standard)
Column A - Desirable Limits
Column B - Permissible Limit in the absence of better alternative source
We have contacted a filter manufacturer. He is willing to install an "Iron Removal Filter" which he says
will remove Colour, Odour, Turbidity and Iron problems.
But for the other chemicals, his "Iron Removal Filter" will not reduce those chemicals. But the technician
says that since they are below "B"-Cause for Rejection, we need not worry.
My Questions:
(1)The filter manufacturer says column A and B are like minimum and maximum. Is he right?
(2)If his "Iron Removal Filter" removes iron, turbidity, colour and odour, will the water be potable with the
other chemicals as above?
Thanks
