"ppm" simply means 'parts per million' and describes the quantity of any substance in water. For example -Iron should be less than 3 ppm.

Pure water is obtained by distillation, demineralization, inverse osmosis; but 7 ppm iron is not so much.
10 ppm mole multiply by molecular weight of water then divided by sample density
A visible sheen can be detected at around 60 ppm oil.
1. Purified water is a homogeneous liquid. 2. Purified water cannot be considered as a mixture because is very pure; impurities are at a level of ppm or less.
ppm by volume is "parts per million" by volume as opposed to ppm by weight. ppm by volume and ppm by weight are not the same thing It has been suggested that the drinking water in West Hampshire be adultery with 1 ppm by volume of fluoride. This is an example of ppm by volume
60 -100 ppm is the currently acceptable hardness level for drinking water in US and Canada.60 -100 ppm is the currently acceptable hardness level for drinking water.
Between 50 ppm and 300 ppm is safe. Better below 100 ppm.
Below 2 PPM
391.03 ppm in November 2012.
The ideal salt level is between 2700-3400 ppm (parts per million) with 3200 ppm being optimal. Before adding salt to your pool, test the water to check your salt level.
115 ppm is 0.0115%.
Residential pools: 1.0 - 3.0 ppm; Commercial pools: 3.0 ppm - 5.0 ppm; Bromine levels: 4.0 - 6.0 ppm
0.o15 ppm
Generally, a TDS level between 50-150 is considered as the most suitable and acceptable. Ans: If the TDS level is about 1000 PPM, it is unsafe and unfit for human consumption.
Basically Water itself in general is pure substance. But most water, including bottled spring water, is a mixture. You can the read the label behind the bottle too. It says: nutrition facts Na....0.1 ppm Cl.....0.2 ppm F......0.05 ppm etc (ppm) means part per million which is good. (PPB) Means part per Billion. (PPT) Means part per trillion. Even natural water has minerals dissolved in it which is good.
Jupiter's atmosphere is composed of the following:Molecular hydrogen (H2) - 89.8% (+/- 2.0%)Helium (He) - 10.2% (+/- 2.0%)Methane (CH4) - 3000 ppm (+/- 1000 ppm)Ammonia (NH3) - 260 ppm (+/- 40 ppm)Hydrogen Deuteride (HD) - 28 ppm (+/-10 ppm)Ethane (C2H6) - 5.8 ppm (+/- 1.5ppm)Water (H2O) - 4 ppm (varies with pressure)Small amounts of aerosols, including ammonia ice, water ice, and ammonia hydrosulfide
0 ppm
