Kennedy,Jenl(s Consultants <br /> Section 2: Project Approach <br /> This Work Plan includes a methodology for assessment of the flux of water and of constituents <br /> of concern. Soil and crop sampling will provide a direct measure of assimilation in the upper <br /> 5 feet of soil. Soil water balance measurements in the upper 5 feet will provide information <br /> about soil water movement, storage, and adequacy for optimum crop growth. This approach for <br /> monitoring the amount of soil moisture and percolating water is derived from the agricultural <br /> industry where ongoing monitoring of crops and soil moisture is vital for the management of <br /> irrigation to maximize crop yield. <br /> The direct soil, soil moisture, and crop sampling approach will be used to evaluate the <br /> constituent uptake and assimilative capacity of various crops within the land application area. In <br /> addition, this Work Plan proposes deeper soil sampling to provide additional data regarding <br /> a) assimilation of process water constituents within the vadose zone and b) the ability of the <br /> irrigation management strategy to decrease downward flux below the root zone. <br /> The Work Plan will be implemented by establishing three test plots to be used for intensive <br /> measurements of soil and crop processes. The study will be conducted for the 2008 and 2009 <br /> growing seasons. Results of the 2008 growing season will be used to develop initial design <br /> criteria for the phase 3 process water treatment design. Results of the 2009 growing season will <br /> be used to refine the phase 3 design criteria. <br /> Crop Uptake and Assimilative Capacity Work Plan, Page 3 <br /> Woodbridge Winery, Acampo, California <br />
