Quality and Chemical Type of Groundwater in Gringsing District, Batang Regency

Abstract

Abstract 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+, HCO 3 − , SO 4 2− 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.
