Groundwater Well Blending Survey

Thank you for taking the time to complete the survey below. When responding to these items, please reference the Groundwater Blending Reference Sheet and Blending Scenario Water Quality Table. The Water Quality Table (Table) contains a summary of predicted drinking water quality for four groundwater blending scenarios (percentage of local groundwater blended with purchased SFPUC treated surface water). These scenarios are part of a preliminary investigation of potential changes to the drinking water system due to the drought. At this time we would like to hear comments from our end users with critical water quality needs or sensitive processes. The water will remain safe, potable, drinking water. However, some quality parameters such as alkalinity and conductivity would vary in a blend with groundwater (see the Reference Sheet and Table at the link below).
