USGS and Bell County Cooperative Science

The USGS Texas Water Science Center, in cooperation with the Clearwater Underground Water Conservation District and Bell County Adaptive Management Coalition, is evaluating the hydrogeology and water quality of the surface water and groundwater resources in Bell County. The results provide regional water managers, who are responsible for regulation of water use and drought management strategies, with a more comprehensive understanding of their local streams and aquifers.

 

Data Collection Activities Federal Fiscal Years (October-September)

2012

Collected water quality samples from:

  • Salado Creek
  • 6 springs in Salado Springs complex
  • 2 Edwards aquifer wells (confined and unconfined)
  • 1 well in the upper Trinity aquifer

2013

Installed low-flow streamflow gage on Salado Creek

Collected paired water-quality samples during baseflow conditions and after light rain from:

  • Big Boiling Spring
  • Stagecoach Inn “cave” well

Collected additional unpaired water-quality sample from Big Boiling Spring

2014

Streamflow gage on Salado Creek expanded to full-range

Collected paired water-quality samples under varying hydrologic conditions from:

  • Big Boiling Spring
  • Stagecoach Inn “cave” well
  • Salado Creek

2015

Streamflow gage operation & maintenance

Collected water- quality samples from:

  • Big Boiling Spring during and after 2 rain events (4 samples total)
  • 3 wells in the upper, middle, and lower Trinity aquifer

Collected paired water-quality samples from:

  • Robertson Spring
  • Robertson well

Geophysical borehole logging of 1 well in the lower Trinity aquifer

2016

Streamflow gage operation & maintenance

Resampled the same 6 springs where water- quality samples were collected in 2012 but at a higher baseflow level

2017

Streamflow gage operation & maintenance

Geophysical borehole logging of 5 wells:

  • upper, middle, and lower Trinity aquifer

2018

Streamflow gage operation & maintenance

Geophysical borehole logging

  • 1 well in the upper Trinity aquifer
  • 1 well in the unconfined Edwards aquifer

Analysis of 20 archived samples collected by Baylor University and the Clearwater Underground Conservation District for nitrate and (or) nitrate isotopes

Collected water-quality samples from Salado Creek for

  • nutrients
  • bacteria
  • microbial source tracking

2019

Streamflow gage operation & maintenance

Geophysical borehole logging of 3 wells:

  • upper and lower Trinity aquifer

USGS Science in Bell County

Salado Creek Bacteria Source Tracking Web Site

The USGS Texas Water Science Center (TXWSC) is collecting surface-water samples from Salado Creek to investigate the concentrations of waste-related constituents and identify their sources (human or other animals) using microbial source tracking.
