Each degree reported up from 7.0 to 14.0 relates to the caustic nature of the water and each degree down from 7.0 down to 0.0 is describes ,the acidity, of the water. Each unit of measurement is 10 times that of the previous number, so if the pH is 4.0, that is 1,000 times more acidic than the neutral pH of 7.0.
