<br /> iI - Distance to Production Wells - M J Kloberdanz & Associates conducted a survey of
<br /> ' municipal, domestic, agriculture, industry and other water wells within a 2000-foot radius
<br /> of the former diesel tank The survey involved contacting the Water Resources Board
<br /> and a physical search of the area Construction details are provided for the wells on
<br /> ' record at the Department of Water Resources (Appendix B) The majority of the
<br /> identified wells are located outside of the 2000-foot radius (Figure 2) Wells observed
<br /> during the 2000 foot radius survey include an irrigation well-,75 feet southeas f_the
<br /> ' former tank, a domestic well 150 feet south of the former tank, a well at the bus
<br /> maintenance yard (1200 feet so—uff o t e to site), and an abandoned production well at
<br /> the former magnesium plant about 1500 feet west of the site
