depends on whether its contaminated or not, there are UK standards and the world health org standards which set the legal limits on what should be in our drinking water and what shouldn't be in the water. i think it also depends on your water source and how hard your water is.
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.
The maximum acceptable level of contaminants in drinking water is typically set at 0.01 parts per million (ppm). This means that water with 0 ppm of contaminants is considered to be of the highest quality, as it contains no harmful substances that could potentially impact human health.
0.o15 ppm
0.1
Between 50 ppm and 300 ppm is safe. Better below 100 ppm.
5 ppm
it should be below 3.5 ppm
A good parts per million (ppm) level for water quality is typically below 500 ppm. This level ensures that the water is safe for drinking and other uses.
Depends what you call "too much". The current acceptable limit is now 3ppm, but I have seen people drinking with over 8 ppm and not being bothered by it.
The recommended safe level of TDS (total dissolved solids) in drinking water is below 500 parts per million (ppm).
It depends what substance there are 10 parts per million of.
The concentration of chloroform in the drinking water sample can be expressed as 0.0015% by mass. This is because 15 ppm represents 0.0015% of the total mass of the sample.
