Spatiotemporal Variation of Groundwater Nitrate Concentration Controlled by Groundwater Flow in a Large Basin: Evidence From Multi‐Isotopes (¹⁵N, ¹¹B, ¹⁸O, and ²H)

Abstract Elevated and increasing concentration in groundwater affect supplies China elsewhere. However, how flow affects has yet to be fully understood. Herein, multi‐isotopes ( 15 N, 11 B, 18 O, 2 H) local indicators of spatial association (LISA) were used elucidate the spatiotemporal variation, sources, patterns its response Poyang Lake Basin where agriculture, industry urban coexist. The location hotspots identified by LISA tended move from middle lower reaches Ganfu Plain with flow, area expanded upper Xin River northwest study during transition dry season wet season. Our results revealed that variations regional controlled recharge or mode (vertical lateral), biogeochemical processes sources (sewage manure). In some areas single stratigraphic structure (unconfined aquifer), variation was influenced pollution vertical current precipitation flow). binary structures (confined mainly recharged lateral affected mixing effect upstream groundwater, reflecting human activities rather than activities. lakeside floodplain, attenuated dissimilatory reduction . This provides a novel insight into controlling on distribution scale.

Under pressure from surface water pollution and climate change, groundwater becomes a critical source. Information on quality could contribute to effective management. This study was carried out utilize multivariate statistical analysis the index (GWQI) evaluate in Ca Mau Province, Vietnam. Twenty-five samples residential-urban areas, cemetery landfill saline intrusion areas were collected for this study. Groundwater evaluated using National Technical Regulation Quality (QCVN 09-MT:2015/BTNMT) GWQI. Principal component (PCA) used identify potential polluting sources key variables influencing quality. Cluster (CA) applied cluster quality, sites recommended future monitoring. The results revealed that NH4+-N contaminated area, while area polluted by TDS NH4+-N. classified as excellent, good, poor, very poor accounted 44, 40%, 12%, 4%, respectively. divided into four groups, mainly based presence of TDS. Nine sampling locations be removed current program but still ensuring representativeness result CA. PCA proposed two main variation at each area: landfilling area. parameters (i.e., pH, TDS, permanganate index, NH4+-N, NO3--N, Fe) should continued monitor. Domestic industrial wastewater discharge, leachate cemeteries landfills, nature aquifers, seawater variation. findings provide scientific information local environmental authorities manage monitor Doi: 10.28991/CEJ-2024-010-03-03 Full Text: PDF

Hydrogeochemical features, genesis, and quality appraisal of confined groundwater in a typical large sedimentary plain

Water Environment Research, Год журнала: 2024, Номер 96(8)

Опубликована: Авг. 1, 2024

Abstract The confined groundwater of arid sedimentary plains has been disturbed by long‐term anthropogenic extraction, and its hydrochemical quality is required for sustainable development. present research investigates the characteristics, formation, potential health threats, suitability in central North China Plain. Results show that a slightly alkaline nature study area, predominantly dominated fresh‐soft Cl‐Na HCO 3 ‐Na types. Water chemistry governed water–rock interactions, including dissolution evaporites cation exchange. Approximately 97% sampled groundwaters exceed prescribed standard F − . It mainly due to geological factors such as mineral dissolution, exchange, competitive adsorption may also be released from compacted soils because extraction. Enriched can pose an intermediate higher non‐carcinogenic risk more than 90% population. poses greatest threat population north‐eastern part especially infants children. For development, use irrigation area should avoided, attention paid soil salinization infiltration risks. In are found excellent or good domestic purposes based on Entropy‐weighted Quality Index. However, caused high contents cannot ignored. Therefore, it recommended differential water supplies implemented according spatial heterogeneity ensure scientific rational resources. Practitioner Points hydrochemistry plain extraction was investigated. multiple drinking were evaluated. characteristics formation mechanism under influence revealed.

Which Pollutants Should Be Prioritized for Control in Multipollutant Complex Contaminated Groundwater of Chemical Industrial Parks?

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Март 17, 2025

Increasing chemical pollutants in groundwater within industrial parks pose a critical environmental challenge, necessitating innovative strategies to address contaminants with the highest risks health and ensure sustainable management. Herein, we investigated 277 from 367 sampling points across 10 rounds, totaling 1,016,590 measured data points. An prioritization index (EHPI) was proposed applied integrate multiple criteria: occurrence, migration, persistence, bioaccumulation, acute chronic toxicity, effects rank target for priority control. Thirty were classified as top-priority group 81 high-priority, metals, polycyclic aromatic hydrocarbons, haloalkanes ranking highest, while emerging of concern ranked lower. The top 6 beryllium, benzo(g,h,i)perylene, nickel, benzo(a)pyrene, chrysene, arsenic. EHPI method compared against five other weighting schemes, including AHP (analytic hierarchy process), entropy, AHP-entropy, AHP-TOPSIS (technique order preference by similarity ideal solution), entropy-TOPSIS. effectively captured integrated results more simplistic schemes. Overall, 38 are recommended inclusion control list, focusing on high detection exceedance categories. This framework provides guidance focused monitoring, assessment, highest-risk pollutants, supporting effective human protection.
