  • Slide 1
  • An Overview of Groundwater Quality in Texas Cary L. Betz, P. G. Groundwater Planning and Assessment Team, Texas Commission on Environmental Quality
  • Slide 2
  • While much of the spotlight has been focused on determining how much groundwater is available, and where it is found...
  • Slide 3
  • Slide 4
  • Slide 5
  • Sampling and analysis of groundwater quality has also been taking place.
  • Slide 6
  • Groundwater Quality Programs USGS National Water Quality Assessment (NAWQA) Program
  • Slide 7
  • TWDB Ambient Groundwater Monitoring Program Groundwater Quality Programs
  • Slide 8
  • USGS National Water Quality Assessment (NAWQA) Program TWDB Ambient Groundwater Monitoring Program TCEQ Public Water Supply Drinking Water Quality Monitoring Program
  • Slide 9
  • NAWQA South Central Texas
  • Slide 10
  • NAWQA South Central Texas Trinity River Basin
  • Slide 11
  • NAWQA South Central Texas Trinity River Basin High Plains Regional Ground Water Study
  • Slide 12
  • Ambient Groundwater Monitoring 129,826 wells
  • Slide 13
  • Ambient Groundwater Monitoring 129,826 wells Anions, Cations, and Infrequent Constituents
  • Slide 14
  • Ambient Groundwater Monitoring 129,826 wells Anions, Cations, and Infrequent Constituents Major Aquifers
  • Slide 15
  • Ambient Groundwater Monitoring 129,826 wells Anions, Cations, and Infrequent Constituents Major Aquifers Minor Aquifers
  • Slide 16
  • Ambient Groundwater Monitoring 129,826 wells Anions, Cations, and Infrequent Constituents Major Aquifers Minor Aquifers Basis for the groundwater portion of the States Water Quality Inventory (305(b) report)
  • Slide 17
  • Public Drinking Water Monitoring Monitors Entry Points to Public Water Supply Systems
  • Slide 18
  • Public Drinking Water Monitoring Monitors Entry Points to Public Water Supply Systems Large suite of potential drinking water contaminants
  • Slide 19
  • Public Drinking Water Monitoring Monitors Entry Points to Public Water Supply Systems Large suite of potential drinking water contaminants Will be integrated into the 2004 Water Quality Inventory
  • Slide 20
  • The Water Quality Inventory For the past three report cycles, has represented selected Ambient Groundwater Monitoring data in a graphic format using GIS software
  • Slide 21
  • The Water Quality Inventory Nitrate was selected as the contaminant to be represented. Maps were constructed using the most recent data gathered for the major and minor aquifers
  • Slide 22
  • The Water Quality Inventory
  • Slide 23
  • For the 2004 edition of the report, other constituents of concern will be examined and represented graphically
  • Slide 24
  • The Water Quality Inventory For the 2004 edition of the report, other constituents of concern will be examined and represented graphically
  • Slide 25
  • The Water Quality Inventory For the 2004 edition of the report, other constituents of concern will be examined and represented graphically including the infrequent constituents
  • Slide 26
  • The Water Quality Inventory This inventory, because of the relatively limited data that is available, cannot completely characterize the groundwater quality in the state
  • Slide 27
  • The Water Quality Inventory Additionally, the report does not seek to assign potential sources of contamination
  • Slide 28
  • The Water Quality Inventory Additionally, the report does not seek to assign potential sources of contamination
  • Slide 29
  • The Water Quality Inventory Additionally, the report does not seek to assign potential sources of contamination
  • Slide 30
  • The Water Quality Inventory Additionally, the report does not seek to assign potential sources of contamination
  • Slide 31
  • The Water Quality Inventory Additionally, the report does not seek to assign potential sources of contamination
  • Slide 32
  • The Water Quality Inventory As has been state in the report for several cycles, The quality of groundwater in Texas is generally good... which is not to say that we have no concerns.
  • Slide 33
  • The Water Quality Inventory Monitoring programs need to be maintained and enhanced to provide the best picture possible of groundwater quality.
  • Slide 34
  • There is Much Work to be Done
