<p style='margin-bottom:0in;'><span style='font-size:12.0pt; font-family:"Arial",sans-serif; color:#4C4C4C; background:white;'>The Aquifer Risk Map is
developed to fulfill requirements of SB-200 (Monning, 2019) and is intended to
help prioritize areas where domestic wells and state small water systems may be
accessing groundwater that does not meet primary drinking water standards
(maximum contaminant level or MCL). In accordance with SB-200, the map is made
available to the public and updated annually starting January 1, 2021. This
layer is part of the 2023 Aquifer Risk Map. The Fund Expenditure Plan states
the risk map will be used by Water Boards staff to help prioritize areas for
available SAFER funding.</span></p><p style='margin-bottom:0in;'><span style='font-size:12.0pt; font-family:"Arial",sans-serif; color:#4C4C4C; background:white;'><br /></span></p>
<p style='margin-bottom:0in; background:white;'><span style='font-size:12.0pt; font-family:"Arial",sans-serif; color:#4C4C4C;'>This layer contains summarized water quality
risk per square mile section for five individual contaminants (nitrate,
arsenic, 1,2,3-trichloropropane, hexavalent chromium, and uranium).</span></p><p style='margin-bottom:0in; background:white;'><span style='font-size:12.0pt; font-family:"Arial",sans-serif; color:#4C4C4C;'><br /></span></p>
<p style='margin-bottom:0in; background:white;'><span style='font-size:12.0pt; font-family:"Arial",sans-serif; color:#4C4C4C;'>The water quality risk is based on
depth-filtered, de-clustered water quality results from public and domestic
supply wells.
