The results of the screening tests indicate reactions ranging from very weak to very strong after the addition of
hydrogen peroxide; pHFQX values 1 pH unit below the pHF value measured in nearly all the samples analysed:
and a significant number of samples analysed yielded pHFQX values below 3 pH units.
