Water Test Report Provided: Potable? Treatment Required?

The following are the parameters of the a water sample from the borewell.

pH at 25 degree C: 7.80

Total Suspended Solids : Nil

Total Dissolved Solids 180 degree C: 1740

Iron as Fe : <.01

Total Hardness as CaCo3 : 560ppm

MG++ hardness CaCo3 : 210 ppm

CA++ hardness CaCo3 : 350 ppm

Calcium ion  : 140 ppm

MG++     : 50.9 ppm

Na+      : 418 ppm

Total alkalinity CaCo3 80 ppm;

P.alkalinity as CaCo3 : Nil

Bicarbonate alkalinity CaCo3 : 80 ppm

Chloride Cl-: 510ppm

Fluoride F-: .38

Sulphate SO4 : 218 ppm

Silica as SIO2 : <.01

Sodium as Na : 418.

My questions are as follows:

1. Is it safe for all usage including drinking or  general usage other than drinking?

2. What effect would it have on the fitted GI water pipelines, any chance of  the lines being choked soon due to use of this water?

3. Kindly suggest if a water softener is required?

Dear Bairaria

1) this water is not suitable for drinking. Water having TDS upto 3000 ppm can be demineralized through reverse osmosis.

2) i have calculated langelier saturation index for this water which comes to be 0.4 to 0.6. This water have scaling tendencies, so choking of GI pipes will take place in short duration. To make this water neither scaling nor corrosive its PH should be 7.4-7.5. I considered 20-30 deg C water temperature for calculating LSI.

3) This water can be treated with reverse osmosis technique. It will lower TDS to 100 ppm. There are many other solutions for lowering TDS but these are complicated and can not be applied in home. so best and easy solution for home is RO treatment.

Dear Rakesh ji,

As per the test report :

1. your water is not suitable for drinking purpose as it is hard and some parameters are present more than acceptable limits which makes it not potable.

2. The G.I.fittings will get chocked soon as the water is high in Chlorides and hardness is also very high.

3. You should go for R.O.treatment of this water to make it suitable for drinking.

Dear Mr.Bairaria,

A scrutiny of the parameters of your bore well water as tested,if compared with BIS-10500 will show that it is not suitable for drinking.It has excessive total hardness and total dissolved solids.The presence of chlorides is also high and this is mostly in theform of Sodium Chloride.The water will be brackish and unpalatable.

The answers to your questions:

1.It would be unpleasant to drink.Since no bacteriological test result is given, can not comment on how safe it will be.At best it could be used for washing yards and gardening.

2.The water will be corrosive and if softened,highly corrosive.Do not use GI pipes,instead use PVC/HDPE or PP pipes as these are all plastic and hence will not corrode.Due to the high TDS level and total hardness, there will be chocking of pipes.

3.As indicated above,softening will make the water very much more corrosive and will not improve the taste in any way. You could try using Reverse Osmosis(RO) to desalinate the water to make it drinkable,but with its high TDS and hardness, most domestic RO systems will have a lot of problems and will not function satisfactorily.

You need to consider Rain Water Harvesting to re-charge the bore well water as it will improve the quality of the water over a period of time.
