Waterbase - Groundwater (5 tables)

Data Table

This page was archived on 16 Jun 2014 with reason: Other (Access to earlier versions of Waterbase-Groundwater data files have been restricted to authorised users only.)

Dataset contains data selected from reporting of member and collaborating countries on chemical quality of groundwater, characteristics of groundwater bodies and sampling sites. Reported data have been assessed and processed by the ETC-Water and the EEA. Disaggregated records were annually aggregated and statistic value calculated. Results of quality assessment have been incorporated into the individual data tables.
