Sampling of High Salinity Groundwater in Texas

Project Summary:

The objective is to obtain water quality samples for higher salinity groundwater (3,000 to 35,000 mg/L Total Dissolved Solids [TDS]) from specific aquifers of interest. The USGS will attempt to obtain direct measurements from more saline aquifers by sampling produced water from oil and gas wells or by sampling deeper water wells (like rig supply wells). Collecting higher salinity samples will both expand the publicly available dataset and provide essential data to estimate TDS from geophysical well logs.

The stakeholders will have access to analytic data for high salinity groundwater and estimates of groundwater salinity derived from geophysical well logs.Water quality sampling is typically focused on shallower and fresher portions of aquifers.It is important to obtain data from deeper portions since there is a lack of publicly available data for higher salinity (3,000 to 35,000 mg/L Total Dissolved Solids).
