Water-Level Altitudes and Changes in Houston-Galveston Region and Montgomery County; the Scientific Story of Groundwater-Levels, Long-term Changes, and Subsidence

Presentation Materials

Topic: The United States Geological Survey (USGS) has been monitoring water table levels in hundreds of water wells on an annual basis in our region for more than forty years. At July's Network meeting, we will have not one-but two-groundwater experts discuss the results from the latest round of measurements and to demonstrate the overall trends that have developed over the past decades of data collection and analysis. Sachin Shah and Jason Ramage will also "make the connection" between groundwater use (withdrawals), subsidence, and population growth. Don't miss this annual summary of these important scientific findings. Hope to see you there on the 27th.

About the Speakers:

  • Sachin Shah is the Chief of Hydrologic Studies and Research at the U.S. Geological Survey (USGS) Gulf Coast Program. Sachin oversees three primary programs in the region: (1) groundwater and subsidence; (2) coastal studies; and (3) lake studies. Sachin has been with the USGS for 11 years in Atlanta, Georgia, and Austin and Houston, Texas primarily studying groundwater resource issues including international transboundary water concerns, geophysical advances in characterizing hydrogeology, and groundwater resource availability. Before re-joining the USGS, Sachin spent five years with the World Bank Water Program and two years as an Associate Fellow with the Council of Energy, Environment and Water researching existing technical options and policies to determine best practices for increasing water use efficiency in rural India and ultimately improve water management. Sachin graduated with an MA in International Development and Policy from the LBJ School of Public Affairs and an MS in Hydrogeology at the University of Texas at Austin.
  • Jason Ramage is a hydrologist with the U.S. Geological Survey Gulf Coast Program and leads the groundwater, compaction, and subsidence studies in the Gulf Coast aquifer system. The majority of his work focuses on developing potentiometric surfaces of the three primary aquifers in the region and their short- and long-term changes as well as compaction and subsidence in the region. Jason also has been involved in groundwater quality sampling in production wells looking at a variety of constituents from major and minor ions, trace metals, radiochemical isotopes, and age dating isotopes. Going forward, his focus will also include studying the development of the Catahoula aquifer in Montgomery County and the effect on depressurization and water quality with ongoing volumetric withdrawal. Jason graduated with a BS degree in Geology from the University of Houston.

Registration for this event is not necessary. We look forward to seeing you on the 27th.
