“…At these places, people are susceptible to diseases like methemoglobinemia in infants, blue baby syndrome, and cancer, due to long-term intake of groundwater [35,36]. Similar results have also been reported in the agriculturally active regions of the world [37,38]. Apart from agricultural sources, sewage effluent has also been observed as a prominent source of nitrate contamination in groundwater in the growing city of Ulaanbaatar, Mongolia [39], which stands true for this region of Jalandhar as well.…”

In the present study, groundwater suitability for domestic and irrigation purposes was analyzed in the alluvial aquifers of the Bist-Doab region of Punjab, India, using various indices such as WQI, WAWQI, MCDA, RSC, SAR, PI, %Na, KR, MH, PS, K, and Ka. Since it is difficult to assess the suitability of groundwater for irrigation based on various indices individually, a composite groundwater quality index for irrigation (CGQII) was used in the study which transforms nine indices to a single value for each sample. Results reveal that the groundwater of a few blocks was found unsuitable for domestic use due to chemical leaching from fertilizers, pesticides, and agricultural and industrial wastes. Whereas, the groundwater of mainly southwestern parts was found unsuitable for irrigation due to long-term water accumulation in aquifers and continuous use of sodium-ion-rich groundwater. The findings conclude that anthropogenic activities have played a significant role in making groundwater unfit for domestic and irrigation purposes in the study area. The present study also emphasizes continuous monitoring and evaluation of groundwater quality, which will help in strategic planning and management for the conservation of groundwater resources in the region.

“…Simple nitrogen-based fertilizers can contain nitrogen in nitric, ammonia, nitric-ammonia and organic forms [11]. Fertilizers with nitrate nitrogen are directly and readily absorbed by plants, while those with ammonia nitrogen, although having the same physiological value, are absorbed directly more slowly, but are mostly used indirectly undergoing transformation into nitrogen in the soil nitrate by nitrifying bacteria [11]. Fertilizers based on organic nitrogen exert their action very slowly, having to undergo successive transformations into ammonia and then nitric nitrogen in the soil.…”

Nitrogen (N) is one of the fundamental elements for plant development: it plays a very important role in biochemical processes, such as chlorophyll photosynthesis, the production of amino acids and proteins, but it is also the most critical element in fertilization. When nitrogen is administered to the soil, in its more complex forms, organic and ureic, it transforms into increasingly simple forms such as Ammonia (NH) and Nitric (NO3) and becomes assailable by plants. Due to its agronomic function, nitrogen represents an element that must be appropriately integrated into the crop cycle through careful fertilization and a careful balance between withdrawals, losses and contributions. The choice of the nitrogen fertilization strategy must obviously aim to guarantee the availability of the element to the crops in the phases in which they need it most, avoiding losses that can represent a threat to the environment or to the crop economic balance. This article has the main purpose of highlighting the impact of the main fertilizations used in the regional agricultural context, in relation to the concentration of nitrogen in its various forms which remains in the soil, thus becoming part of a potential environmental impact both of the matrix itself and of the aquifers. Below, through the analysis of the main crop types. The conclusion is the impact of the main crop type and them fertilization on the soil in particular for the nitrogen compounds.

“…Nitrate pollution in groundwater is a global environmental concern (Cui et al, 2014;Jang et al, 2017;Nai et al, 2020;Torres-Martínez et al, 2021). Despite the development of various measures to control nitrate pollution in groundwater (Gibert et al, 2019;Hu et al, 2019;Zambito Marsala et al, 2021;Gao et al, 2023), effectively controlling the increasing nitrate levels in groundwater remains a persistent and challenging issue.…”

Physical barrier has been proven to be one of the most effective measures to prevent and control seawater intrusion (SWI) in coastal areas. Mixed physical barrier (MPB), a new type of physical barrier, has been shown to have higher efficiency in SWI control. As with conventional subsurface dam and cutoff wall, the construction of MPB may lead to the accumulation of nitrate contaminants in coastal aquifers. We investigated the SWI control capacity and nitrate accumulation in the MPB using a numerical model of variable density flow coupling with reactive transport, and performed sensitivity analysis on the subsurface dam height, cutoff wall depth and opening spacing in the MPB. The differences in SWI control and nitrate accumulation between MPB and conventional subsurface dam and cutoff wall were compared to assess the applicability of different physical barrier. The numerical results show that the construction of MPB will increase the nitrate concentration and contaminated area in the aquifer. The prevention and control efficiency of MPB against SWI is positively correlated with the depth of the cutoff wall, reaching the highest efficiency at the minimum effective dam height, and the retreat distance of the saltwater wedge is positively correlated with the opening spacing. We found a non-monotonic relationship between the change in subsurface dam height and the extent of nitrate accumulation, with total nitrate mass and contaminated area increasing and then decreasing as the height of the subsurface dam increased.The degree of nitrate accumulation increased linearly with increasing the height of the cutoff wall and the opening spacing.Under certain conditions, MPB is 46%-53% and 16%-57% more efficient in preventing and controlling SWI than conventional subsurface dam and cutoff wall, respectively. However, MPB caused 14%-27% and 2%-12% more nitrate accumulation than subsurface dam and cutoff wall, respectively. The findings of this study are of great value for the protection of coastal groundwater resources and will help decision makers to select appropriate engineering measures and designs to reduce the accumulation of nitrate pollutants while improving the efficiency of SWI control.
