Potential Corrosivity Scores of Untreated Groundwater in Louisiana
Four indices—the Langelier Saturation Index (LSI), Ryznar Stability Index (RSI), Puckorius Scaling Index (PSI), and the Potential to Promote Galvanic Corrosion (PPGC) — in addition to an analysis which normalized the results from the existing indices, the Combined Index (CI), were used to assess the potential corrosivity of groundwater in Louisiana. The text file 'potential corrosivity scores.txt' contains identification, location, depth, and aquifer assignment for each site used in this study along with the calculated score for the five aforementioned indices. The average scores of all samples by index are as follows: LSI, −1.28; RSI, 9.78; PSI, 9.34; and CI, 4.14. The PPGC does not produce a numerical score, but the total percentage of class counts can be used to assign a classification; overall, samples in Louisiana were classified as significant concern for corrosion.
