As reported on December 9, 2019, CC&V collected fourth quarter compliance groundwater samples from <br /> monitoring wells SGMW-6B, GVMW-8A,and GVMW-813 on November 12,2019. CC&V received the lab report for <br /> these analyses on December 3,2019,and upon review,determined that SGMW-6B exceeded established numeric <br /> protection limits for fluoride, manganese,and sulfate,GVMW-8A exceeded established numeric protection limits <br /> for fluoride,and GVMW-8B exceeded established numeric protection limits for fluoride. Table 6 below lists the <br /> exceedance for the location and the associated parameter. <br /> Table 6. <br /> Value Table <br /> Location Sample Date Parameter NPL(mg/L) Standard <br /> (mg/L) (mg/L) <br /> SGMW-613 11/12/2019 Fluoride 8.07 2.0 2.0 <br /> SGMW-6B 11/12/2019 Manganese 6.39 3 0.05 <br /> SGMW-613 11/12/2019 Sulfate 992 250 250 <br /> GVMW-8A 11/12/2019 Fluoride 2.05 2.0 2.0 <br /> GVMW-8B 11/12/2019 Fluoride 2.5 2.0 2.0 <br /> As reported on January 16, 2019, CC&V collected fourth quarter compliance groundwater samples from <br /> monitoring well CRMW-313 on December 9,2019.
