pH 
The pH value of water, on a scale of 0 to 14, measures the concentration of hydrogen ions. Pure distilled water is considered neutral, with a pH reading of 7. Water is basic if the pH is greater than 7; water with pH of less than 7 is considered acidic. pH is measured on a logarithmic scale, thus a change in 1.0 units of pH is equivalent to a 10 fold change in acidity. Most vulnerable species, such as brook trout, are sensitive to changes in pH; immature stages of aquatic insects and immature fish are extremely sensitive to low pH values.
