Multivariate statistical evaluation of dissolved trace elements and a water quality assessment in the middle reaches of Huaihe River, Anhui, China
TLDR
The results of the water quality index (WQI) indicate that water in the Huaihe River is heavily polluted by trace elements, so approximately 96% of the river water is unsuitable for drinking and a health risk assessment suggests that Co, Cd and Pb in the river could cause non-carcinogenic harm to human health.About:

Distribution, Sources and Water Quality Evaluation of the Riverine Solutes: A Case Study in the Lancangjiang River Basin, Tibetan Plateau
TL;DR: The assessments indicate that the river waters in the middle-lower reaches are generally suitable for irrigation and drinking purpose, and will not lead to health and soil problems, such as soil compaction and salinization, and the water quality status can be affected by natural weathering processes in the area without anthropogenic inputs.

Heavy metal pollution and environmental risks in the water of Rongna River caused by natural AMD around Tiegelongnan copper deposit, Northern Tibet, China
TL;DR: In this paper , river water and acid mine drainage data were collected to analyze the distribution characteristics of heavy metals and the phytoplankton community in the Rongna River and the environmental risks of heavy metal were evaluated by single-factor pollution index, Nemerow pollution index and health risk assessment model.

TL;DR: In this paper, the authors evaluated the performance of partial least-square regression (PLSR) and multiple linear regression (MLR) in estimating the pollution load index (PLI) based on data for the four trace elements (nickel (Ni), cobalt (Co), chromium (Cr), and boron (B)).

TL;DR: In this paper, the implications of rainstorm were taken into consideration by investigating spatial and temporal variation of dissolved heavy metals (HMs) in the Lijiang River water, and a total of 68 water samples were collected during low flow (normal) season and high flow (rainstorm) season from 34 sampling sites.

Multivariate statistical techniques for the evaluation of spatial and temporal variations in water quality of Gomti River (India)—a case study
TL;DR: This study presents necessity and usefulness of multivariate statistical techniques for evaluation and interpretation of large complex data sets with a view to get better information about the water quality and design of monitoring network for effective management of water resources.

Application of factor analysis in the assessment of groundwater quality in a blackfoot disease area in Taiwan
TL;DR: The over-extraction of groundwater is the major cause of groundwater salinization and arsenic pollution in the coastal area of Yun-Lin, Taiwan and this model explains over 77.8% of the total groundwater quality variation.

Assessment of seasonal and polluting effects on the quality of river water by exploratory data analysis
TL;DR: In this article, an ANOVA of the rotated principal components has demonstrated that mineral contents are seasonal and climate dependent, thus pointing to a natural origin for this polluting form and pollution by organic matter and nutrients originates from anthropogenic sources, mainly as municipal wastewater.

Ecological risk assessment of heavy metals in sediment and human health risk assessment of heavy metals in fishes in the middle and lower reaches of the Yangtze River basin
TL;DR: Investigation of the middle and lower reaches of the Yangtze River in China found that heavy metals may be mainly derived from metal processing, electroplating industries, industrial wastewater, and domestic sewage, and Hg may also originate from coal combustion.
