Abstract

There are more than 70 small tofu factories in the Jogoroto District, which generate a large amount of liquid waste from tofu processing that has not been treated optimally. This certainly creates a potential for the waste to contaminate groundwater in the Jogoroto District. The assessment of groundwater vulnerability to contamination can be conducted using the DRASTIC method, which involves 7 parameters.In this study, there are 24 dug well points spread across the entire Jogoroto District, which were monitored periodically over a 5-month period, from July 2023 to November 2023. Based on the resulting groundwater vulnerability distribution map, laboratory tests on groundwater quality were carried out, using parameters from the Minister of Health Regulation No. 2 of 2023 concerning clean water and the Minister of Environment Regulation No. 5 of 2014 on effluent quality standards.The study found that the DRASTIC index value during the research period ranged from 140 to 212, with three levels of vulnerability: moderate, high, and very high. The high vulnerability level dominated the study area. However, based on the validation results, it was found that the groundwater quality in the Jogoroto District, Jombang Regency, is not contaminated.

Abstract

Activities in the Beji River area such as bathing, washing, toilets, industry, and agriculture greatly affect the declinein the quality of the river's. Poor river surface water quality will affect the quality of groundwater in the area around the river.Groundwater and river surface water have a close relationship with each other, especially in areas around riverbanks. Therefore,this study was conducted to identify the interaction between ground air and river surface air at the research location. Based onthe description of the flow pattern identified as a whole, the type of interaction at the research location is in the form of gainstream. The relationship between the two causes similar characteristics as evidenced by the occurrence of similar patterns in thetime series analysis. These similarity characteristics are divided into 2 clusters, namely cluster 1 is influenced by pH and airtemperature while cluster 2 is influenced by TDS and DHL water with correlation values ranging from -0.074 to 0.972. Based onthe PCA analysis, the eigenvalue values obtained range from 1.042 to 1.482 with a cumulative contribution of variables of 79.58%.The hydrochemistry of air in groundwater and river surface water also shows that there are similarities in the chemical propertiesof air, namely that it has non-dominant types of cations and anions.
