Black & Veatch, the engineering firm contracted to administer the ongoing pilot test at Sweeney Water Treatment Plant, has released its monthly update on the pilot test results.
The monthly update shows that breakthrough has now occurred in the Ion Exchange test. As reported previously, breakthrough occurs when filter media fill with compounds and begin to allow those compounds through the filtration process into the drinking water. All filter media will eventually experience breakthrough, and the purpose of the pilot test is to measure how quickly that occurs after regeneration.
Black & Veatch suggests that the next step is to test additional media and longer contact times to ensure that the pilot test is pursuing and evaluating all possible designs.
We have received the results for November 21 from our on-going GenX testing at the Sweeney Water Treatment Plant. Levels of GenX continue to remain below the DHHS health goal of 140 ppt.
