Mr. Todd Del Frate - 2 - <br /> FIRST <br /> 2 - <br /> FIRST SEMESTER 2013 GROUNDWATER AND SURFACE WATER MONITORING REPORT; <br /> FOOTHILL SANITARY LANDFILL <br /> Results of the data from the recent"rain year' at the Evapotranspiration (ET) closure cover test pad will <br /> be discussed in the next semiannual report. Previous data show that our ET cover performs twice as <br /> well as an intact prescriptive cover. <br /> Surface water and storm water samples were not available this semester due to lack of rain. <br /> Removal of LFG condensate from the secondary sump of Module 1 continues automatically. Water level <br /> in the secondary sump is maintained below 4 inches by pumping three times weekly. <br /> I certify under penalty of law that I have personally examined and am familiar with the information <br /> submitted in this document and all attachments and that, based on my inquiry of those individuals <br /> immediately responsible for obtaining the information, I believe that the information is true, accurate, and <br /> complete. I am aware that there are significant penalties for submitting false information, including the <br /> possibility of fine and imprisonment. <br /> If you have any questions, please call me at(209) 468-8504. <br /> Sincerely, <br /> W.
