Application of Corrosion Indices to Unconfined Aquifer Samples of Mahoba District, U.P. State, India for Domestic Purposes | Chapter 4 | Current Advances in Geography, Environment and Earth Sciences Vol.2
This research seeks to assess the degree of corrosivity and calcite formation in groundwater sampled from Indian Mk. II handpumps in the Mahoba district of Uttar Pradesh, India, using various indices. The study used metrics such as the Langelier Saturation Index, Ryznar Stability Index, Puckorius Scaling Index, Larson-Skold Index, and Potential to Promote Galvanic Corrosion. Because groundwater is corrosive, elements used in pipe construction will leak into drinking water, which is used for both domestic and drinking purposes. Calcite formation reduces the amount of effort required to manually pump out the required volume of groundwater from the aquifer by limiting the convey potential of pipes. A total of 155 samples were collected from Indian Mk. II handpumps accessing shallow aquifers (up to 35 mbgl) in various places for measurement of basic parameters like pH, TDS, EC, and ions like calcium, magnesium, sodium, potassium, chloride, carbonate, bicarbonate, sulphate, and others. Overall, groundwater samples demonstrate a tendency to deposit calcium carbonate within pipes, with chlorides and sulphates not interfering with natural film formation in pipes or the possibility of galvanic corrosion, while a minority of samples show the opposite. Information produced from various corrosion indices can also be used prior to the development of companies that require rigorous water quality parameters for production, and places free of groundwater corrosion potential can be identified for future infrastructure investment.
