The Marina Coast Water District is focused on creating accurate models of groundwater distribution and sediment types to ensure sustainable water management. Due to limited well data, they employ geophysical methods like SkyTEM and Electrical Resistivity Tomography (ERT) to gather comprehensive subsurface information. These methods help map sediment types and water conductivity, crucial for understanding groundwater dynamics and the impact of desalination projects. The district aims to balance water input and output, ensuring long-term resource sustainability.
