New groundwater model predicts clean water in southwest portion of Pleasanton
A new model of the area’s groundwater basin suggests that new wells in southwest Pleasanton could supply PFAS-free water for at least 20 years if built, but questions remain on some of the model’s assumptions. The update, performed by the Zone 7 Water Agency and its consultant, EKI Environment and Water, Inc., collected data from new geophysical studies, pumping tests and third parties to replace the previous 2016 model of the area’s aquifer. … Based on the new model, Zone 7 Water Resources Manager Ken Minn concluded that new wells in southwest Pleasanton would not draw the PFAS plume into the area, nor would they adversely affect existing pumping operations elsewhere in the basin.
