NGWA Webinar to Present Results of Well Grouts Study in Nebraska

November 11, 2011

Scientific investigation finds grouts performed differently than expected

The National Ground Water Assn. will host a free webinar Nov. 18 at 11 a.m. EST, which will present the results discovered during a scientific investigation into water well construction practices that will help ensure groundwater is safe to drink.

More than 800 hours of videotape document the progression of the sealing properties of all types of well grouts during a 16-month study in three distinctly different geologic regions of Nebraska. Researchers found that the grouts performed differently than expected and what had been assumed by the groundwater industry for decades. The visual documentation of the grouts provides the industry with a clearer insight of what is needed for adequate groundwater protection.

Webinar presenter Tom Christopherson is program manager for Nebraska’s Water Well Standards and Contractors’ Licensing Program for the Department of Health and Human Services. Christopherson also serves as the 2011 presenter of the William A. McEllhiney Distinguished Lecture Series in Water Well Technology, a program of the National Ground Water Research and Educational Foundation.
