The Fund Expenditure Plan states the risk map will be used by Water Boards staff to help prioritize areas for available SAFER funding. The map is not intended to estimate or predict water quality contaminant at any given location.</span></p> <p style='margin-top:12.0pt; margin-right:0in; margin-bottom:0in; margin-left:0in; background:white;'><span style='font-family:"Arial",sans-serif; color:#4C4C4C;'><span> </span>In accordance with SB-200, the map is made available to the public and updated annually starting January 1, 2021.
