The report was well written and included <br /> the necessary elements (i.e., Stiff diagrams) which supported the interpretations provided by the <br /> geologists/hydrogeologists. The report was submitted in compliance with Waste Discharge Requirements <br /> (WDRs) Order No. 5-01-148,Provision F.7, which states: <br /> "T The Discharger shall submit to the Board every five years,beginning 1 June 1997, a technical <br /> report which discusses the following issues: <br /> a. A summary of actions taken to reduce the dissolved solids in it s discharge from the plant and <br /> the treatment system to the ponds and irrigation fields. <br /> b. A hydrogeologic analysis on the effects of the reduction in dissolved solids in the <br /> discharge on the semi-perched aquifer, the upper aquifer,the intermediate aquifer, and the <br /> lower aquifer. The analysis should include a determination whether or not the existing <br /> discharge is having a negative impact on the local water quality." <br /> Comments <br /> 1. Introduction: The report references rescinded WDRs Order No. 96-219 and respective Sections. Please <br /> ensure that your consultant(s) has a copy of WDRs Order No. 5-01-148 to ensure that Fox River Company <br /> maintains compliance with the latest version. <br /> 2. Groundwater Quality: As the reports states, in summary,23 percent(%) of the wells onsite show an <br /> increasing trend, 43% show a decreasing trend, and 34% show no trend based on trend analyses using the <br /> Mann-Kendall test. Based upon the analysis using Stiff diagrams for anions and cations in groundwater, <br /> the overall water quality May be improving at onsite monitoring wells. The City of Ripon municipal wells <br /> include MW-3,MW-4,MW-7,MW-9,MW-10,MW-11, and MW-12, which are located all over Ripon <br /> and represent the variation in background water quality throughout the area. Cations from these wells plot <br /> within the cation ranges of Mill wells. Anions, however,plot somewhat differently, especially for wells <br /> MW-10,MW-11, and MW-12. City well MW-11 shows a higher relative percentage of chloride and lower <br /> relative percentage of sulfate, similar to Mill production well PW-8 and wells MW-10 and MW-12 show <br /> lower relative chloride and higher relative sulfate. City well MW-9 is located closest to the site and shows <br /> similar water quality characteristics to the onsite monitoring wells.
