Assessing the groundwater suitability for drinking purposes around disposal area of aluminium slag waste in Jombang Regency, Indonesia– a review.

Aluminum slag wastes are categorized as hazardous waste so that their disposal in the soil without any treatment can cause serious environmental problems, especially groundwater contamination. This paper aims to assess the suitability of groundwater for drinking purposes around aluminum slag waste disposal areas in SumobitoSub district and Kesamben Subdistrict, Jombang Regency. The disposal area that potentially contaminates groundwater is estimated at 31.367 m² with a volume of 96.470 m³. This study executed a comprehensive literature review of aluminum slag waste characteristics, the environmental impact, groundwater contamination, and management. The methods were monitoring results in 28shallow wells around the disposal area using in situ measurement for parameter pH, temperature TDS, conductivity. Results show that groundwater quality in Bakalan Village, Sebani Village, Talun Kidul Village, Carangrejo Village, Kendalsari Village, and Budug Villageexceed the Indonesian standard for drinking water. This paper attempts to provide a preliminary study for decision-making in groundwater management in the affected area. Further study for the heavy metal parameter in groundwater around the disposal area needs to be conducted. [ABSTRACT FROM AUTHOR]
