Online Course: Management and Interpretation of Water Chemistry Data

PortadaTutorialECA (1).png

The current environmental activity and the demands of regulatory bodies require intense monitoring of the quantity and quality of ground and surface water. Given that, the water cycle processes are spatially and temporally distributed, there is a special emphasis on interpreting water chemistry data in a way that provides "information" about the original state of water resources, natural variations and the impact related the implementation of projects.

Hatarilabs offers the virtual course of Management and Data Interpretation of Water Chemistry for students and professionals of any country. Now you can train in Water Chemistry Data Management and Interpretation without any established schedule anywhere. To access the available material and receive support, you just have to make a payment. The course includes certification.



This theoretical-practical course has the following objectives:

  • Provide tools for the representation of water chemistry data.
  • Provide a theoretical basis on water quality variations associated with spatial and temporal aspects.
  • Analysis and interpretation of the status of water quality in a study area.


Course content

The sessions consist of a theoretical introduction plus a practical part and interpretation. The exercises will be solved with the help of Python and GIS software.


Session 1

Theoretical Part

  • Statistical methods for the evaluation of water quality.
  • Introduction to the standard SQL query language and its application for water chemistry.

Practical part

  • Development of chart of boxes for the temporary representation of variation in water quality components.
  • Queries of SQL databases of georeferenced chemical parameters. Generation of thematic maps in filtered data.

Session 2

Theoretical Part

  • Statistical methods for the evaluation of water quality - continued.

Practical part

  • Analysis of statistical distributions of chemical components with Python.

Session 3

Theoretical Part

  • Larger ionic species and ionic balance. Representation of the chemical composition.

Practical part

  • Development of Piper's diagram and chemical analysis regarding the location of the samples in the quadrants of the diagram for a study area.

Session 4

Theoretical Part

  • Main geostatistical methods in the environment.
  • Analysis of groundwater and surface water interaction in chemical variation in the dry season and wet season.
  • Interconnection of water chemistry with other variables of the water cycle: climate, precipitation, relief and land use.

Practical part

  • Analysis of methods of interpolation of chemical parameters. Generation of thematic maps of isolines of chemical components.
  • Development of a Stiff diagram with the data of a project, spatial representation and analysis of the tendencies of concentrations.

Session 5

Theoretical Part

  • Chemical composition of groundwater and surface water. Main processes that affect the chemistry of groundwater.

Practical part

  • Generation of hydrochemical sections. Analysis of trends with respect to distance to a body or watercourse. Evaluation of the main processes that affect the chemical composition.

Session 6

Practical part

  • Spatial and temporal analysis of nutrient contamination with QGIS and Time Manager.
