Groundwater Lecture Series

The Henry Darcy Distinguished Lecture Series in Groundwater Science fosters interest and excellence in groundwater science and technology. It was established in 1986 and named in honor of Henry Darcy of France for his 1856 investigations that established the physical basis upon which groundwater hydrogeology has been studied ever since.

Each year, a panel of scientists and engineers invites an outstanding groundwater professional to share his or her work with their peers and students through this lecture series. The Darcy Lecture Series is most often presented at universities and professional associations throughout the world.

NGWA regrets to announce that the William A. McEllhiney Distinguished Lecture Series in Water Well Technology will be concluding in 2023. Established in 2000, this prestigious lecture series has played a vital role in promoting excellence in the field of water well technology. Named in honor of William A. McEllhiney, a distinguished groundwater contractor and civil engineer, and the founding president of the National Ground Water Association in 1948, the series has been a source of valuable insights and experiences for the industry.

We extend our heartfelt appreciation to all the past lecturers, participants, and organizers who have contributed to the success and legacy of this lecture series. Though it saddens us to see this chapter close, we take pride in the lasting impact it has had on water well technology.

We encourage everyone to view videos of our past lectures to honor the spirit of excellence that William A. McEllhiney himself embodied, and commemorate the inspiring contributions made by all the distinguished lecturers over the years.

Thank you for your unwavering support, and we look forward to seeing you at one of our other events.
