WebPPM is the US standard unit of measurement in water chemistry. It tells us the density of a given substance dissolved in water. Examples include free chlorine, calcium hardness, and total alkalinity. 1 PPM means that substance is one-millionth of the total amount of water. It seems like a tiny amount–and it is–but water does not always need ...
