A uranium and gross alpha radionuclide removal pilot study was conducted for the City of Grand Island, Nebraska on their South Basin water supply. Naturally occurring radionuclides in the Grand Island's raw water source exceed the current Maximum Contaminant Levels (MCL's) for uranium and gross alpha.
The City of Grand Island selected Water Remediation Technology's (WRT) Z-92® Uranium Treatment Process as a possible cost effective solution to their uranium and gross alpha problem. WRT provided a 1.5 GPM (gallons per minute) treatment system, which was delivered and installed on June 30, 2009.
The purpose of this pilot study is to document the effectiveness of the WRT system on high uranium and gross alpha water and to provide information necessary to meet regulatory compliance.
The treatment system has successfully met uranium and gross alpha compliance at all times during the pilot study. The system was in operation for 93 days prior to writing this report and effectively reduced the level of uranium and gross alpha to less than the MCL.
