The results of the sampling <br /> are detailed in this document as follows. <br /> BACKGROUND <br /> The former Spreckels Sugar Plant No. 2 was constructed in approximately 1916. Sugar beets <br /> were transported from the farm to the processing plant via trucks and railcar. The loaded trucks <br /> and railcars were weighed at the scales, and the beets were unloaded at the unloading station. <br /> The Spreckels Manteca plant most recently used a series of conveyors, but formerly utilized an <br /> underground beet flume which utilized water to transport the beets from the unloading area to the <br /> factory. After unloading the beets were washed. The wash water contained soil and other <br /> substances (possibly agricultural chemicals including various herbicides and pesticides) and was <br /> transported to the mud ponds for disposal. <br /> The accumulated pond bottom sludge may have contained elevated concentrations of metals or <br /> other hazardous substances. The sludge from the pond bottoms was periodically removed and <br /> spread on site. In its "Phase I Environmental Site Assessment..." (dated October 18, 1996) <br /> (Kleinfelder File No. 20-3978-01.1`01), Kleinfelder recommended the further assessment of the <br /> pond bottoms and the random areas where sludge may have been spread. <br /> 20-3978-0I.W35/2017R551 Page No. I of <br /> Copyright 1997,Kleinfelder, Inc.
