Geologic Assessments for Regulated Activities Over the Edwards Recharge/Transition Zone

Frost GeoSciences has performed hundreds of Geologic Assessments along the San Antonio/Austin corridor, and is well-versed in the requirements and standards of the Texas Commission for Environmental Quality (TCEQ), formerly the Texas Natural Resource Conservation Commission (TNRCC).

The services to be provided for the geologic assessment include the following tasks:

  • Researching available geologic maps, Flood Insurance Rate Maps, and topographic maps for the area.
    Researching available soils information published by the U.S.D.A. Soil Survey.
  • Visual reconnaissance of the property to identify any manmade or karst features that could provide potential recharge for the sensitive Edwards Aquifer. The site reconnaissance consists of systematically walking the property to provide an overlapping field of view.
  • Using state of the art Global Positioning System technology combined with the most recent aerial photograpy available to obtain accurate coordinates for potential recharge features located in the field. These coordinates are included in the report to assist the planning engineers/surveyors to prepare a Water Pollution Abatement Plan (WPAP) or Sewage Collection System (SCS) report for submittal to the TCEQ.
  • Marking all potential recharge features identified in the field with flagging so that they may be easily found at a later date by planning engineers/surveyors and/or the TCEQ representatives. The flagging is marked in the field with the same potential recharge feature I.D. number as will be used in the report.
  • Preparing high quality geologic maps along with the TCEQ Geologic Assessment Table that includes all of the above mentioned information.

The results of the geologic assessments will be presented in a high quality report prepared and sealed by a Certified Professional Geologist.
