You’ve heard about the unprecedented findings regarding annular seals revealed by the Nebraska Grout Task Force’s nine-year study into the performance of grouting materials — now hear what’s being done about the wells that were constructed prior to this study.
Before 1988, Nebraska had no construction standards for irrigation, livestock, domestic, commercial, or industrial-use water wells. Since 1900, the state has registered 93,105 irrigation wells, 66,084 of which were installed before the adoption of standards. In an effort to address existing water wells with little or no annular seal, Nebraska created the Annular Seals Research Task Force with the mission of how to develop methods to retroactively place meaningful grout materials in the annular space of existing water wells without destroying the wells.
The current research project is focusing on three distinct areas of concern:
The project, scheduled to be completed by early 2014, should provide the state with answers to address the challenges of protecting groundwater where the construction of an active water well predates the regulations. Furthermore, the findings from this study and previous studies will be able to provide significantly improved methods of well construction, rehabilitation, and proper decommissioning.
This study is a joint project of government agencies, the Nebraska Well Drillers Association, the University of Nebraska, industry suppliers of drilling and grout products, and several consultants.
