Database Hydrochemistry

Geohydrochemical database of water analyses on different groundwaters and mineral waters. This database currently manages well over 20,000 water analyses spread across the country. More than 11000 analyses were analysed by the DG in its own laboratory. These are full analyses that take into account the full inorganic ingredients of groundwater. These correspond approximately to the parameter catalogue A of the groundwater quality directive 3/93 (HRSG: National Working Group Water). By default, the following ingredients are considered: physical parameters: Conductivity, temperature, ph-value chemical parameters: — Cations — potassium, sodium, calcium, magnesium, iron, manganese — anions — chloride, hydrogen carbonate, sulphate, nitrate — total hardness/carbonate hardness — carbonic acid content since 1990, the metals are also recorded as standard for in-house analyses.
