Water quality is an aspect that is increasingly being considered in water management efforts. This is caused by the increasing frequency of water pollution problems. The purpose of this study was to analyze the quality and chemical type of groundwater in Gringsing District. Water quality analysis used in this study is a quantitative descriptive analysis by comparing the results of water quality analysis with water quality standards. To determine the chemical type of groundwater, the Stuyfzand method was used through analysis of the concentration of the dominant ions of groundwater, i.e. Ca²⁺, Mg²⁺, Na⁺, K⁺, HCO3− , SO42− and Cl^-. The results showed that in general the quality of groundwater in the study area is suitable for use as a source of drinking water. There were only 4 water samples whose concentration did not meet the quality standards. The chemical type of groundwater in the study area varies greatly. There was only 1 type of groundwater found in the 2 samples, i.e. type F/0/Ca²⁺/HCO₃ ^-/+, namely groundwater with a chloride content of less than 150 mg/l or fresh water, the dominant ion being calcium and bicarbonate and the addition of fresh water. and balanced saltwater.

巴塘县 Gringsing 区地下水水质及化学类型

水质是水管理工作中越来越多地考虑的一个方面。这是由于水污染问题日益频繁造成的。本研究的目的是分析格林辛区地下水的质量和化学类型。本研究采用的水质分析是通过将水质分析结果与水质标准进行比较来进行定量描述性分析。为了确定地下水的化学类型，采用Stuyfzand方法通过分析地下水主要离子Ca ²⁺、Mg ²⁺、Na ⁺、K ⁺、 碳酸氢根3- , 所以42− 和^Cl-。结果表明，研究区地下水水质总体适宜作为饮用水水源。仅4个水样浓度不符合质量标准。研究区地下水化学类型差异较大。 2个样品中仅发现1种地下水，即F/0/Ca ²⁺ /HCO ₃ ^- /+型，即氯化物含量低于150 mg/l的地下水或淡水，主要离子为钙和碳酸氢盐以及添加淡水。和平衡盐水。
