Abstract

The water source that is widely used to meet the domestic needs of people in the Diwek District, Jombang Regency is ground water through the use of dug wells. The groundwater at this location has the potential to be polluted by industrial waste. To anticipate this, research is needed on assessing the level of intrinsic vulnerability of groundwater to pollution based on the physical properties of rocks. The aim of this research is to assess the level of intrinsic vulnerability of groundwater to pollution and map its distribution. This research was carried out on 24 samples of dug wells in the Diwek District area which were observed periodically for 5 months from July 2023 to November 2023. The assessment of the level of intrinsic vulnerability of groundwater to pollution was carried out using the Simple Vertical Vulnerability (SVV) method based on 3 parameters i.e. the type of water unsaturated zone material (La), recharge/percolation (Wu), and the thickness of the water unsaturated zone (Z). Based on the research results, it can be stated that the SVV index value during the research period ranged from 14.89 to 40.96 with 3 categories of groundwater vulnerability levels, namely medium, high and very high. The distribution of groundwater vulnerability levels in the research location is dominated by medium vulnerability with an area varying from 46% - 48% of the study area.

Abstract

An area of 1,853 ha (65.2%) of land in Megaluh District is used for rice fields. Pesticides and inorganic fertilizers are widely used as plant fertilizers in Megaluh District, where excessive use in rice fields can pollute the groundwater below. This research is aimed at identifying spatially the possibility of groundwater pollution using the hydrogeological approach of the SINTACS method. The SINTACS method has five scenarios that produce different weights for each parameter that can cause groundwater vulnerability. The data used in the SINTACS method are groundwater depth, infiltration rate, unsaturated zone, soil texture, aquifer media, hydraulic conductivity and topography. This research uses variations in the depth of the groundwater level to determine the trend in the level of groundwater vulnerability in Megaluh District during the rainy season and dry season with a severe impact scenario as an approach to environmental conditions in Megaluh District. The results of the analysis show that the level of groundwater vulnerability in Megaluh District is in the range of 143.6 (rather high) – 198 (high). The percentage of rice field area which reached 65.2% resulted in a rather high level of vulnerability of 42.35% and a high level of vulnerability of 57.65%.
