“…Groundwater nitrate vulnerability can be described as the sensitivity of an aquifer's susceptibility to nitrate contamination, based on the redox environment in both the aquifer material and the overlying geological strata 55 , 56 . In groundwater, the presence of nitrate is due to various sources and origins.…”

An increased nitrate (NO3−) concentration in groundwater has been a rising issue on a global scale in recent years. Different consumption mechanisms clearly illustrate the adverse effects on human health. The goal of this present study is to assess the natural and anthropogenic NO3− concentrations in groundwater in a semi arid area of Rajasthan and its related risks to human health in the different groups of ages such as children, males, and females. We have found that most of the samples (n = 90) were influenced by anthropogenic activities. The background level of NO3− had been estimated as 7.2 mg/L using a probabilistic approach. About 93% of nitrate samples exceeded the background limit, while 28% of the samples were beyond the permissible limit of 45 mg/L as per the BIS limits. The results show that the oral exposure of nitrate was very high as compare to dermal contact. With regard to the non-carcinogenic health risk, the total Hazard Index (HITotal) values of groundwater nitrate were an average of 0.895 for males, 1.058 for females, and 1.214 for children. The nitrate health risk assessment shows that about 38%, 46%, and 49% of the samples constitute the non-carcinogenic health risk to males, females, and children, respectively. Children were found to be more prone to health risks due to the potential exposure to groundwater nitrate.

An increased nitrate (NO3-) concentration in groundwater has been a rising issue on a global scale in recent years. Through different consumption mechanisms, it clearly illustrates the adverse effects on human health. The goal of this present study is to assess the natural and anthropogenic NO3- concentration in groundwater and its related risks to human health in the different groups of ages such as children, males, and females. Groundwater samples (n=101) were obtained and analysed for their physicochemical components, along with the nitrate concentration in a semi-arid area of Rajasthan. The results show that most of the samples were influenced by anthropogenic activities. The background and anthropogenic levels had been estimated and marked as 7.2 mg/L and 13.3 mg/L for the background and anthropogenic concentrations, respectively. About 83% of nitrate samples were exceeded the background limit, while 28% of the samples were beyond the permissible limit of 45 mg/L as stated by the Bureau of Indian Standards (BIS). Nitrate health risks were also measured by oral intake and dermal contact sources for the residents in this area. The oral exposure of nitrate was very high as compare to dermal contact. With regards to the non-carcinogenic health risk, the total Heath Index (HITotal) values of groundwater nitrate in the study area varied from 0.045 to 3.153 with an average of 0.964 for males, 0.053 to 3.726 with an average of 1.139 for females, and 0.061 to 4.278 with an average of 1.308 for children. The nitrate health risk assessment shows that about 38%, 46%, and 49% of groundwater samples constitute the non-carcinogenic health risk to males, females, and children, respectively.

“…Suatu potensi atau kondisi dimana sistem airtanah dapat bertahan terhadap sumber pencemar dari permukaan hingga kedalam akuifer dapat didefiniskan sebagai kerentanan airtanah (Harter & Walker, 2001;Putranto et al, 2016). Percepatan pencemaran airtanah dapat dipengaruhi oleh kondisi hidrogeologi dari formasi batuan dalam sifat kelulusan airtanah (Febriarta & Oktama et al, 2020;Voutchkova et al, 2021). Sumber pencemar secara dinamis dapat dipengaruhi oleh sumber pencemar serta kondisi infiltrasi hingga mencapai zona jenuh air, sehingga dapat mengakibatkan risiko pencemaran rendah pada daerah dengan sumber pencemar (polutan) yang tinggi (DPU, 1996;Putranto et al, 2020;Vrba & Zaporozec, 1994).…”

“…Lathamani et al, (2015) menyebutkan bahwa penilaian kerentanan airtanah dapat diperoleh dari kombinasi parameter sifat pembawa air (kondisi geologi). Putranto et al, (2020) dan Voutchkova et al, (2021) menyatakan bahwa parameter hidrogeologi merupakan parameter yang mempengaruhi percepatan penyebaran pencemaran. Oleh karena hal tersebut penilaian kerentanan airtanah terhadap pencemaran dapat diperoleh dari perhitungan multi kriteria dari kecepatan kelulusan airtanah, dengan metode DRASTIC (Aller et al, 1987a;Sugianti et al, 2016).Berkaitan dengan peningkatan akses informasi dalam pembangunan berkelanjutan, maka diperlukan pemetaan tentang sumber daya air secara keruangan (spasial) mengenai potensi, lokasi, sebaran airtanah yang dangkal, dan kondisi kerentanan yang dipengaruhi oleh faktor penysusn batuan yaitu dominasi batugamping bioklastik fragmental dan terumbu, yang rentan terhadap sumber pencemar (polutan) di Pulau Bakalan.…”
