This facility uses three of their four supply wells as their <br /> means for supplying drinking water to their facility. The facility wells are sampled on <br /> a monthly basis and have consistently shown that the tetrachloroethylene plume <br /> extends past the corrective action monitoring wells AMW 13 and AMW 14 as shown <br /> in the following table. Furthermore, the tetrachloroethylene in Well #2 has <br /> concentrations which at times which exceed the US EPA Primary MCL of 5 ug/I. <br /> Well #1, #2 and #4 all exceed the public health goal of 0.06 ug/I for <br /> tetrachloroethylene <br /> Northern California Youth Authority Wells <br /> Tetrachloroethylene Concentrations (ug/11) <br /> 11/ 07 12/07 01/08 02/08 03/08 04/08 05/08 6/08 <br /> Well #1 3.2 3.8 3.8 4.0 4.2 3.9 3.8 3.3 <br /> Well #2 4.4 4.8 5.4 4.0 5.7 5.4 5.6 6.7 <br /> Well #4 1.3 1.5 1.4 1.4 1.5 1.5 1.6 ND <br /> • U.S. EPA Primary MCL = 5 ug/I <br /> • Public Health Goal = 0.06 ug/I <br /> 17.On 24 April 2007 the California Department of Health Services, Division of Drinking <br /> Water and Environmental Management issued Citation No. 03-10-07C-004 to the <br /> North California Youth Authority for failure to comply with Section 116566 of the <br /> California health and Safety Code. Specifically, the system failed to comply with the <br /> primary drinking water standard for tetrachloroethylene as specified in Section <br /> 64444 Maximum Contaminant Levels - Organic Chemicals of Title 22, California <br /> Code of Regulations during March 2007. Citation No. 03-10-07C-004 has been <br /> attached as Appendix A of this Order. <br />
