Groundwater Data Enhancements
The Groundwater Centre (TGWC) has been maintaining a groundwater database for over 20 years. TGWC has merged the
Alberta Environment (AENV) GIC database with its own database. This process
allowed TGWC to dramatically upgrade the existing AENV
groundwater dataset. TGWC continuously updates it's database to reflect the
AENV database changes.Listed below are some of the TGWC enhancements.
(updated March 2006)
