TL;DR: In this paper , the authors focus on those areas with the highest interference between humans and stygofauna: cities, where local pollution by various contaminants and heat strongly stresses the unique groundwater ecosystems.

TL;DR: In this article , the authors reported existence of microcystins (MCs) in groundwater due to surface-water and groundwater interaction and showed that MCs concentrations in these groundwater wells might pose adverse health effects to both adults and children during summer, but not during winter.

TL;DR: In this paper , the authors used the REMChlor-MD model to evaluate how matrix diffusion can serve as an attenuation mechanism for the leading edge of a plume of non-degrading compounds like perfluoroalkyl acids (PFAAs), including perfluorooctane sulfonate (PFOS).

TL;DR: In this paper, the authors reported the existence of microcystins (MCs) in groundwater due to surface-water and groundwater interaction and showed that MCs concentrations in these groundwater wells might pose adverse health effects to both adults and children during summer, but not during winter.

TL;DR: In this article , a well-known thermodynamic-based model for predicting the Aaw-Sw relationship is evaluated through comparisons to literature data collected using various measurement techniques for model sands and a limited number of soils using data collected from the current published literature.

TL;DR: In this paper , the authors employed numerical modeling of density-dependent flow and multiple-species solute transport, and then employed these metamodels in a version of the ensemble Kalman filter (EnKF) termed the 'constrained restart dual EnKF (CRD-EnkF)' algorithm.

TL;DR: In this paper , the authors introduced the use of novel co-processed biomass extracted from the olive tree leaves for the adsorption of lead from contaminated water, and the results showed that the biomass co-processing enhanced the adaption capacity of lead.

TL;DR: In this paper , a Bayesian isotope mixing model (Simmr) was used to reduce the uncertainty in estimating the contributions of different pollution sources in the Yufu River watershed.

TL;DR: In this paper , microplastic pollution in different environments has increasingly been documented in detail in recent times, but it is still poorly studied in caves and karst aquifers.

TL;DR: In this paper , the authors collected microplastic samples from water and sediments during the wet and dry seasons and collected satellite remote sensing images of the algae density in Chaohu Lake.

TL;DR: In this article , the authors examined the groundwater quality and health concerns using a random sampling process, where multivariate statistical and health risk analyses of elements were performed to determine the source of contaminants and their effects on human health.

TL;DR: In this article , the authors explore the deposition kinetics of DNA-tagged silica tracer for different pore water chemistries, flow rates, and sand grain size distributions in a series of saturated sand column experiments in order to predict environmental conditions for which the DNA-tags tracer can best be employed.

TL;DR: In this article , a comprehensive model is established by combining EPIC crop growth module, soil and groundwater water-salt balance models, and multi-objectives 0-1 programming.
