BRACS studies

BRACS studies can be conducted in-house by Innovative Water Technologies staff or externally by a consulting firm under contract with TWDB and staff member managing the contract. A study typically consists of:

  • evaluating publically available water well records, geophysical well logs, and geologic reports,
  • entering information into the BRACS Database,
  • comparing top, bottom, and lateral extent of water–bearing geologic formations,
  • interpolating data points from BRACS Database to build new formation structures,
  • mapping the water-bearing portions of the aquifer and their hydraulic properties,
  • estimating salinity from water well records and geophysical well logs,
  • estimating volumes of brackish groundwater,
  • preparing geographic information system files, and
  • writing a report summarizing findings.

The TWDB has completed eight studies and is currently working on eight more studies.
