Any water which has a TDS water level below 500 ppm is good to go. According to WHO, water containing 1000 ppm TDS is acceptable for consumption. However, it is a good decision to always have water with lesser salts. This measure should never go below 30 ppm or else its a risk to our health.

So. 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: Vapor Pressure PPM on Volume Dew Point (Water/Ice in Equilibrium) Basis at 760 mm Relative Humidity PPM on Weight °C °F mm of Mercury of Hg Pressure at 70°F% Basis in Air-90 -130 0.00007 0.0921 0.00037 0.057-88 -126 0.00010 0.132 0.00054 0.082-86 -123 0.00014 0.184 0.00075 0.11-84 -119 0.00020 0.263 0.00107 0.16-82 -116 0.00029 0.382 0.00155 PPM, or parts-per-million, is a way of expressing very dilute concentrations of substances. Usually describes the concentration of something in water or soil. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg). In water solution, the concentration C in parts-per million (ppm) is equal to 1000 times the concentration C in grams per kilogram (g/kg) and equal to 1000000 times the concentration C in grams per liter (g/L), divided by the water solution density at temperature of 20ºC 998.2071 in kilograms per cubic meter (kg/m 3) and approximately equal to Water hardness follows these guidelines: 0 - 4 dH, 0 - 70 ppm : very soft 4 - 8 dH, 70 - 140 ppm : soft 8 - 12 dH, 140 - 210 ppm : medium hard 12 - 18 dH, 210 - 320 ppm : fairly hard 18 - 30 dH, 320 - 530 ppm : hard higher : liquid rock (Lake Malawi and Los Angeles, CA) General hardness is the more important of the two in biological processes. 70 ppm Makeup Alkalinity for Desired pH 70 ppm/4 COC 17.5 ppm Required Reduction in Cooling Water Alkalinity 200 -17.5 182 ppm Sulfuric Acid Required per ppm of Alkalinity Reduction 1 ppm of 93% (66 Baume) Acid per ppm Alkalinity reduction 182 ppm x 1 = 182 ppm Pounds /day of Acid Required for Alkalinity Reduction 182 ppm X 7.
