“…Some regulations such as those of DOI: 10.1002/adsr.202300073 the World Health Organization have been put in place to limit the NO 3 − concentration in potable water to 50.0 mg NO 3 − L −1 (806.0 μm). [6] Therefore, monitoring nitrate levels in groundwater and drinking water is relevant to the public health sector in terms of quality control and prevention of toxicity.…”

The unique electrochemical and electronic properties of CuxO (Cu2O/CuO) give it merit to be used in the development of electronic devices. This paper presents the facile chemical route for the development of a sensitive, accurate, and low‐cost nitrate electrochemical sensor based on undoped and Sn‐doped CuxO thin film electrodes. Various characterization techniques are used to study the physical, electro‐chemical, and electronic properties of the material. Sn‐doping resulted in an increase in the number of electron transfers from 1 to 2 as compared to undoped CuxO. The prepared sensor exhibited a high sensitivity of 100.3 µA mm−1 cm−2, a wide linear concentration range of up to 50.0 mm, a fast response time of <5.0 s is observed at a potential of −1.0 V (vs Ag/AgCl), and a very low limit of detection of 0.1 µm (S/N = 3.0) that outperformed those in the recent literature. The electrode is selective for nitrate in the presence of common interference species and exhibited chemical stability and reproducibility.

Groundwater is crucial for meeting the water needs of rural communities, serving both domestic and agricultural purposes. However, its quality in our study area remains unclear. Therefore, the primary objective of the current study is to evaluate the groundwater quality and ascertain the level of contamination risk associated with the use of septic tanks in rural communities within the Al Hoceima province. This will be achieved by conducting a comprehensive analysis of physicochemical parameters and employing effective indices, including the Water Quality Index (WQI), Nitrate Pollution Index (NPI), and Chronic Health Risk (CHR). In February 2023, we collected samples from 33 wells, spanning densely and sparsely populated regions, to account for potential variations in water quality. The analyzed parameters included pH, total dissolved solids (TDS), electrical conductivity (EC), ammonium (NH 4 + ), nitrates (NO 3 -), nitrites (NO 2 -), sodium (Na + ), potassium (K + ), calcium (Ca 2+ ), magnesium (Mg 2+ ), chloride (Cl -), sulfate (SO 4 2-), bicarbonate (HCO 3 -), phosphate (PO 4 3-), and silica (SiO 2 ). Our findings revealed slightly alkaline groundwater with TDS levels ranging from 1508.63 mg/l to 8289.8 mg/l, with an average of 3223.19 mg/l. The cation dominance sequence observed was Na + > Ca 2+ > Mg 2+ > K + > NH 4 + , while for anions, it followed as SO 4 2-> Cl -> HCO 3 -> NO 3 -> PO 4 3-> NO 2 -. The Water Quality Index (WQI) indicated contamination in 54.55% of the wells, with notably higher NPI values in densely populated regions. This suggests anthropogenic nitrate contamination, likely originating from septic tanks. The assessment of Chronic Health Risk (CHR) revealed non-carcinogenic health risks in 27.27% of samples for children and 15.15% for adults. Given these findings, it is imperative for Moroccan authorities, despite the efforts of the Loukkos Hydraulic Basin Agency (LHBA), to implement strategic measures to protect groundwater quality in densely populated rural regions.

“…These pose a danger to the sustainability of the landuse system. The most notable degradation process is the salinization of groundwater [3]. Therefore, the aim of this study was to identify the problem of water salinity, identify areas at risk, and find solutions for the management of these resources.…”
