This paper is an attempt to utilize the various indices available to assess the degree of corrosivity and calcite formation of groundwater sampled from Indian Mk. II handpumps from the district of Mahoba in Uttar Pradesh. The indices used include Langelier Saturation Index, Ryznar Stability Index, Puckorius Scaling Index, Larson-Skold Index, and Potential to Promote Galvanic Corrosion. Corrosivity of groundwater would cause materials used in construction of pipes to leach into drinking water since the same is used for household activities and drinking purposes. Calcite formation would affect the amount of exertion used to manually pump out required quantity of groundwater from the aquifer as it reduces the convey potential of pipes. One hundred five groundwater samples were collected from Indian Mk. II handpumps tapping shallow aquifer (up to 35mbgl) from different locations that were used by locals for analysis of basic parameters like pH, TDS, EC, ions like calcium, magnesium, sodium, potassium, chloride, carbonate, bicarbonate, sulphate, etc. Overall, majority of the groundwater samples display tendency to deposit calcium carbonate within the pipes, chlorides and sulphates not interfering with natural film formation in pipes and possibility of galvanic corrosion, whereas minority of the samples indicate the alternate scenario.

本文尝试利用各种可用指标来评估从印度Mk采样的地下水的腐蚀性和方解石形成的程度。II泵来自北方邦Mahoba地区。所使用的指数包括朗格里尔饱和指数，Ryznar稳定性指数，Puckorius比例指数，Larson-Skold指数和促进电腐蚀的潜力。地下水的腐蚀性会导致用于管道建设的材料渗入饮用水中，因为该材料用于家庭活动和饮用目的。方解石的形成会影响用来手动从含水层中抽出所需量的地下水的消耗量，因为它降低了管道的输送潜力。从印度Mk收集了155个地下水样品。
