“…The concentration of NO 3 -N in the Ordos Basin is 4.7 times higher than that in this study. The concentration of NH 4 -N in this study is not different to that in the Netherlands [19], but higher than that in Young-am City [20] and the Ordos Basin [18]. This shows that the hydrochemical components of the shallow groundwater in this study are affected by human activities.…”

In recent years, the impact of the excrement from large-scale poultry farms on the quality of shallow groundwater has attracted widespread attention. In the present study, the hydrogeochemical characteristics of shallow groundwater around poultry farming sites in the town of Zhuxianzhuang in Suzhou, Northern Anhui, China, were investigated using various statistical techniques, a Piper trilinear diagram, ion combination ratios, correlation analysis, and a fuzzy comprehensive evaluation method. The results show that the shallow groundwater in the area is dominantly of the HCO 3 -Ca type. The relative abundances of the major cations and anions in the groundwater are in the order Na + >Ca 2+ >Mg 2+ >K + and HCO 3According to the concentrations and distribution of tri-nitrogen in the groundwater, pollution is mainly associated with domestic wastewater, followed by poultry farm waste. The most severe pollution involves NO 2 -N, and this adversely impacts the potability of the shallow groundwater. The leaching of rocks and silicate weathering are the principal processes responsible for the ionic composition of the shallow groundwater in the study area. Class I, II, and III waters account for 9.52%, 28.57%, and 61.90%, respectively, of the groundwater in the area. The shallow groundwater is suitable for high salinity-tolerant plants or soils associated with good leaching conditions. Future water management in the poultry farming area should prioritize the control of shallow groundwater nitrite pollution.

“…Previous studies have shown that such livestock mortality leachate contains high concentrations of inorganic and organic compounds (e.g., ammonium, alkalinity, chloride, sulfate, BOD, and COD) as a result of carcass decomposition 37 , 55 , 56 . The lower ORP in the leachate (median = -66 mv) compared to the surrounding groundwater (median = 115 mv) is due to anaerobic conditions prevailing in the burial pits 44 , 57 , 58 . The carcass leachate leakage from burial pits thus induces the subsequent increases of ionic concentrations in groundwater, exhibiting positive correlations with EC and TDS concentrations but negative correlations with ORP.…”

This study introduces a novel groundwater pollution index (GPI) formulated through compositional data analysis (CoDa) and robust principal component analysis (RPCA) to enhance groundwater quality assessment. Using groundwater quality monitoring data from sites impacted by the 2010–2011 foot-and-mouth disease outbreak in South Korea, CoDa uncovers critical hydrochemical differences between leachate-influenced and background groundwater. The GPI was developed by selecting key subcompositional parts (NH4+-N, Cl-, and NO3--N) using RPCA, performing the isometric log-ratio (ILR) transformation, and normalizing the results to environmental standards, thereby providing a more precise and accurate assessment of pollution. Validated against government criteria, the GPI has shown its potential as an alternative assessment tool, with its reliability confirmed by receiver operating characteristic curve analysis. This study highlights the essential role of CoDa, especially the ILR -transformation, in overcoming the limitations of traditional statistical methods that often neglect the relative nature of hydrochemical data. Our results emphasize the utility of the GPI in significantly advancing groundwater quality monitoring and management by addressing a methodological gap in the quantitative assessment of groundwater pollution.

“…Principal Component Analysis (PCA) has been widely used to assess groundwater quality and to identify underlying processes such as groundwater contamination [39][40][41][42] . Moreover, it serves as an objective method for calculating water quality indices (WQI) through weighted linear combinations by selecting and weighting important groundwater quality parameters 43 .…”

This study introduces a novel Groundwater Pollution Index (GPI) formulated through compositional data analysis (CoDa) and robust principal component analysis (RPCA) to enhance groundwater quality assessment. Using groundwater quality monitoring data from sites impacted by the 2010–2011 foot-and-mouth disease outbreak in South Korea, CoDa uncovers critical hydrochemical differences between leachate-influenced and background groundwater. The GPI was developed by selecting key subcompositional parts (NH4+-N, Cl−, and NO3-−N) using RPCA, performing ilr transformation, and normalizing the results to environmental standards, thereby offering a more precise and reliable pollution assessment. Validated against government criteria, the GPI demonstrated its potential as an alternative assessment tool, confirmed by receiver operating characteristic (ROC) curve analysis. The study underscores the importance of CoDa, especially the isometric log-ratio (ilr) transformation, in overcoming the limitations of traditional statistical methods by focusing on the relative nature of hydrochemical data. By bridging a methodological gap in groundwater assessment, the GPI represents a significant advancement in groundwater quality monitoring and management. Our results emphasize the importance of considering the compositional nature of environmental data and show the utility of multivariate statistical methods in enhancing the precision and reliability of pollution assessments.
