Assessment of Groundwater Vulnerability Using GOD Method

Abstract

Mining activities can affect the availability of groundwater both in quantity and quality. Example of mining activities that can cause pollution are overburden stockpiling, construction of haul road facilities and infrastructure, coal processing and stockpiling activities, workshops, and domestic waste disposal. One effort to maintain groundwater is to analyze the groundwater vulnerability. This research was conducted to analyze the vulnerability of groundwater to pollution of PT. X in Balangan, South Kalimantan. The method used to assess groundwater vulnerability in this study is the GOD method (groundwater occurrence or aquifer type, overall lithology of aquifer, and depth of groundwater). Determining the groundwater vulnerability class with this method will be based on three parameters, namely type of aquifer, lithology or rock type, and depth of groundwater table. The GOD method divides each parameter into several classes in consonance to the weight of each parameter corresponding to the effect on groundwater vulnerability. Based on the results of the analysis, it is indicated that the area of PT. X is included in the category of negligible and moderate vulnerability. The results of the analysis can be used for recommendations for groundwater management in the study area. The GOD method can also be used to determine groundwater vulnerability in urban areas that have different land uses.

Groundwater Vulnerability Comparison Using DRASTIC and GOD Methods in Surakarta City

“…Each parameter has a different contribution to the results of the GOD vulnerability level (Djoudi et al, 2019), with its criteria (Sugianti et al, 2017). GOD vulnerability assessment was conducted by calculating the index for the region, according to equation 2 (Rukmana et al, 2020).…”

Tinjauan Literatur Sistematis dan Analisis Bibliometrik Penelitian Kerentanan Airtanah di Indonesia (2013-2021)

“…Penelitian kerentanan airtanah selain memiliki keragaman secara lokasi juga memiliki keragaman secara metode yang digunakan. Hasil tinjauan literatur sistematik menunjukkan ada beberapa metode yang digunakan dalam penelitian kerentanan airtanah di Indonesia diantarnaya GOD (Sukmawati Rukmana et al, 2020;Widodo et al, 2021), DRASTIC (Aribowo et al, 2021b;Kesuma et al, 2017;Koesuma et al, 2021;Machdar et al, 2018;Putranto & Aribowo, 2020;Wicaksono et al, 2013), HGZ (Klaas et al, 2017(Klaas et al, , 2018, COP (Yogafanny & Legono, 2021), APLIS (Syafarini et al, 2021), SVV (Aribowo et al, 2021a), EPIK (Riyanto et al, 2020;Syahidin & Murti, 2021), AVI Putranto & Yusrizal, 2018;Siswoyo & Azhar, 2019), SINTACS dan SINTACS Lu (Ayu Wandari et al, 2020;Primastuti & Kusratmoko, 2018), SI (Marjuanto et al, 2019) , DRANTHVP (Ahadiah & Widyastuti, 2020), PCSM (Putranto & Marjuanto, 2021). Selain satu metode tunggal ada juga yang menggunakan integrasi beberapa metode diantaranya GOD dan DRASTIC , AVI -GOD -SINTACS -DRASTIC (Nugraha et al, 2020)…”

Aquifer Vulnerability: Its Protection and Management—A Case Study in Pangkalpinang City, Indonesia

“…Groundwater level depth is another important parameter in determining groundwater vulnerability [34]. Table 6 shows the depth of groundwater value/rating in the study area.…”

“…Groundwater Confinement. Groundwater confinement is one of the parameters used in the analysis of groundwater vulnerability [34]. Groundwater confinement can be interpreted based on subsurface conditions using vertical electrical sounding (VES).…”
