地下水资源在伊朗卡拉杰平原等大多数干旱/半干旱地区发挥着至关重要的作用。挖掘威尔斯和开采含水层的水资源长期以来一直被认为是供应饮用水、农业和工业用水需求的普通解决方案。在上述地区等许多农业地区，抽水威尔斯井被用于饮用和农业消费，而为监测水质和保护公众健康而采取的措施却非常有限。另一方面，该地区大部分用于饮用的共用抽取威尔斯井都位于农田附近，它们受到农药污染的风险很高。本文首先对饮用水水质指数（DWQI）和灌溉水水质指数（IWQI）的结果进行了论证，然后确定了这两种方法在对威尔斯井进行排序时可能引起的冲突。为了减少冲突的影响，采用了妥协规划法（CP）和逼近理想解排序法（TOPSIS）。据澄清，MCDM在一定程度上缓解了威尔斯等级的矛盾-由DWQI/IWQI确定-并证实这一程序是农业社会水质等级的适当方法。
Groundwater resources play a crucial role in most arid/semi-arid regions such as Karaj plain, Iran. Excavation of wells and exploiting water resources of aquifers have long been known as ordinary solutions to supply water demands for drinking, agricultural and industrial purposes. In many agricultural areas such as the above-mentioned region, extraction wells have been utilized for both drinking and agricultural consumptions, while measures taken for water quality monitoring and protecting public health are seriously limited. On the other hand, most of the shared extraction wells in the region used for drinking purpose have been located near the agricultural lands and they are highly under the risk of getting polluted by Agricultural pesticides. The current paper firstly intends to demonstrate the results obtained from Drinking water Quality Index (DWQI) as well as Irrigation Water Quality Index (IWQI) and secondly determines probable conflicts that may be aroused in ranking of water wells using these two methods Subsequently, Multi Criteria Decision Making (MCDM) techniques such as Ordered Weighted Averaging (OWA), Compromise Programing (CP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) were employed to decrease effects of the conflicts. It was clarified that MCDMs, to some extent, alleviated contradictions in wells’ ranks −determined by DWQI/IWQI- and authenticated this procedure as an appropriate method for water quality ranking in agricultural societies.
