North Hollywood West Well Field Water Treatment Project

Document Description: Note: Extended Review Per Lead The LADWP proposes to implement a response action to address releases of 1,4-dioxane in groundwater that are migrating to the North Hollywood West Well Field. This response action would be achieved by installing water treatment equipment at the well field capable of removing the 1,4-dioxane to below identified cleanup levels. It would minimize the spread of contaminant mass, limit further degradation of the groundwater basin directly downgradient of the NHW wells, remove contaminant mass from the aquifer, assist in the restoration of beneficial uses of the groundwater basin, prevent the ingestion of groundwater that exceeds cleanup levels, and restore LADWP's capability to operate its existing NHW Well Field.
