This survey is part of California Department of Water Resources’ (DWR) project to conduct airborne electromagnetic (AEM) geophysical surveys throughout the state. The surveys are being conducted to improve the understanding of groundwater resources and support the local and state goal of improved groundwater management and implementation of the Sustainable Groundwater Management Act (SGMA). The surveys are funded through voter-approved Proposition 68 and there is no additional cost to locals. DWR’s video provides more information about EM surveys: https://www.youtube.com/watch?v=HMSZdzzOrUE.
AEM data are collected fringe a large hoop towed beneath a helicopter. the method is safe and surveys have already successfully been conducted in several locations throughout California. Surveys will only be conducted during daylight hours and the helicopter will not fly over business, homes, other inhabitable structures or confined animal feeding operations. The helicopter operator follows all established Federal Aviation Administration rules and regulations, and their highest priority is public safety.
