Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
This study was conducted to assess the groundwater suitability for drinking and irrigation and to recognize the comprehensive controls of groundwater salinization in the coastal regions of the Thiruvallur district. For this purpose, groundwater from 54 dug and bore wells at locations covering most of the coastal aquifer within 10 km was sampled and analyzed for various physicochemical parameters. The analytical results expose that the groundwater in the study area is slightly alkaline to alkaline, moderately fresh to highly saline, and very high in hardness. The dominance of significant ion concentrations was found in the following order: (Formula Presented). The Water Quality Index (WQI) map shows that 70% of the groundwater samples are unsuitable for drinking due to the enhanced levels of TDS, salinity, and significant major ionic concentrations. However, the rest of the groundwater samples are in excellent to good condition. The Hydrochemical Facies Evaluation Diagram (HFE-D) reveals that many samples show the over-lapping in the mixing line between fresh groundwater and saltwater caused by seawater intrusion.
