We have also included a copy of your <br /> 15 February 2005 letter as an enclosure. <br /> Chapter 2 — Process Water Characterization Work Plan <br /> Woodbridge recognizes that inorganic dissolved solids or Fixed Dissolved Solids (FDS) are <br /> important to the overall process water characterization evaluation. We have included Total <br /> Dissolved Solids (TDS) and Volatile Dissolved Solids (VDS) analyses in Table 6 of the <br /> Groundwater Protection Work Plan which is a list of the proposed analyses for process water <br /> streams in order to derive the FDS portion by calculation.We have also proposed the necessary <br /> analyses to derive the cation/anion balances for the process water streams. We have not <br /> deemphasized reduction of FDS and it is clearly stated in Chapter 6, Section 6.1.2 that we will <br /> "...compare the results of the process water characterization to the results of the treatment <br /> evaluation, and identify and describe potential process water, salinity, and nitrate reduction, <br /> reuse, recycling, and treatment opportunities." However, it is important to collect information on <br /> many constituents, not just focus on salinity. Also,we need to collect information on degradable <br /> constituents in order to optimize the process water treatment processes. <br /> g:usv Wwa"niat3030123.DO_M tlanl06 wWnMgn ad&nA I.Ooc <br />
