NGA OFFICIAL LAUNCH


The Department of Water and Sanitation (DWS), Directorate: Hydrological Service is delighted to announce the launch of the centralised web-enabled National Groundwater Archive (NGA) to external clients.

The NGA is accessible 24 hours a day. All clients with a direct interest in groundwater can register to search, capture and store data. Registered users can also extract data directly via the Internet.

To register go to: http://www3.dwa.gov.za/nganet
Enquiries: ngaur [at] dwa [dot] gov [dot] za

Currently the main focus of NGA is on point data known as Geosites (boreholes, dug wells, seepage ponds, springs, etc). Groundwater data that can be captured in the NGA module structure include Geosite Information, Casings / Linings, Field Measurements, Operational Recommendations, Pumping Test Details etc.
Geology module will be made available in the near future.
