Total acidity, drinking water samples

Acidic Croup Analyses. [COOH] and total acidity values are reported in Table VIII. Two distinct groupings can be recognized according to the two sample categories, although one CFH sample presents a [COOH] value (i.e., CFH-2) similar to at least three values found for the drinking water samples.
