| Summary: | Quantitative distribution of main ions and other chemical components of groundwater
are characterized by theirs statistical parameters. They depend closely on probability distribution of the data. In this paper, by rocessing 760 analysis results of groundwater samples issued by Department of Geology and Minerals of Vietnam, and by using frequency analysis techniques, the authors show that the distribution of bicarbonate and calcium ions in Pleistocene and Holocene
aquifer in the Red River Delta (RRD) are in accordance with normal distribution, while other ions are in accordance with skew distribution. In the first case, the value of mean equals the value of median, but in the second case, these two values should be determined at the percentile of 50% and 80% respectively. This research also indicated that Pleistocene and Holocene aquifers belong to
bicarbonate ‐ calcium type with total mineralization in Pleistocene aquifer significant less than that in Holocene one. |
