Hydrochemical data from underground water samples from Piracambaia II, Campinas, Brazil

Hydrochemical data from water samples collected in two distinct seasonal periods: 19 samples in a rainy period (April 2019) and 20 samples in a dry period (August 2019). The dataset is characterized by a spreadsheet with a total of 39 lines and 49 columns, where: * The first column (column 0) identifies the water sample collection point; * Column 1 contains the date of sample collection; * Columns 2 to 33 contain the cation variables for each sample collected; * Columns 34 to 38 contain the anion variables for each sample collected; * Column 39 contains the Dissolved Organic Carbon in each sample collected; * Columns 40 to 43 contain the variables of the physical-chemical aspects of the collected samples; * Columns 44 to 46 contain the variables of the isotopic analysis of the collected samples; * Columns 47 and 48 contain the geographic coordinates (in UTM format) of each water collection point. The domestic wells were named ``WX´´, where X is the enumeration given by the researchers who carried out the collections. The collection point for the river's surface water was called ``river´´. The collection point for surface water from the meander was named `meander´´.
