The Northern California Youth Authority (NCYA) facility is located due north and <br />approximately 1,000 feet downgradient of the Austin Road Landfill monitoring wells <br />AMW 13 and AMW 14. 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, assuming there are no other sources of such contaminants <br />contributing to contamination of the NCYA wells. Furthermore, the <br />tetrachloroethylene in Well #2 has concentrations which at times which exceed the <br />US EPA Primary MCL of 5 ug/I. Well #1, #2 and #4 all exceed the public health goal <br />of 0.06 ug/1 for tetrachloroethylene <br />i. <br />19:0 9 -. 0-o a Z Lai 4 Z 19 -. 9 i <br />• U.S. EPA Primary MCL = 5 ug/I <br />• Public Health Goal = 0.06 uo/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 />11/07 <br />12/07 <br />01/08 <br />02/08 <br />03/08 <br />04/08 <br />05/08 <br />6/08 <br />Well #1 <br />3.2 <br />3.8 <br />3.8 <br />4.0 <br />4.2 <br />3.9 <br />3.8 <br />3.3 <br />Well #2 <br />4.4 <br />4.8 <br />5.4 <br />4.0 <br />5.7 <br />5.4 <br />5.6 <br />6.7 <br />Well #4 <br />1.3 <br />1.5 <br />1.4 <br />1.4 <br />1.5 <br />1.5 <br />1.6 <br />ND <br />• U.S. EPA Primary MCL = 5 ug/I <br />• Public Health Goal = 0.06 uo/I <br />17.
