These waters were subjected to an accelerated corrosion test to classify their corrosivity, and the measured corrosion rates subjected to correlation checks against the chemical species in the sample. It was found that bicarbonate and a negative Longelier Index of the waters were the chief contributors to corrosion. Treatment with lime or removal of oxygen are methods recommended to control the corrosion rate.enThesis
